Inflation protection is costly

Rampant inflation is Public Enemy No 1 for most investors. (That is assuming you’ve already got yourself and the active fund industry behind bars).

Our standard defence? Index-linked government bonds – affectionately known as ‘linkers’ in the UK.

Linkers are a special type of government bond1 that automatically pump up your regular coupons and ultimate principal payouts in line with RPI inflation.

The easiest way to buy ‘em? Index-linked government bond tracker funds.

But there’s a problem with these funds in the UK – a potential mismatch between what you may think you’re buying and what you’re actually buying.

There’s a danger that your inflation protection could be drowned out by interest rate risk – that is, the possibility that your bond fund suffers large capital losses if market interest rates do take off.

The reason for this is that the UK’s index-linked bond funds are stuffed full of linkers that mature many decades from now.

These long-dated bonds (maturing in the 2030s, ’40s, ’50s and ’60s) are highly sensitive to market interest rate changes.

Fluctuating prices and yields

When market interest rates fall, bond prices rise because their coupons (that is the rate of regular interest they pay) are more competitive compared to new issues coming on to the market.

Investors buy more of the more generous-paying bonds, driving up their prices and reducing their yield, until they trade in line with their peers and the new, lower interest rate regime.

The same is true in reverse. When interest rates rise, a bond’s price falls as its fixed coupon now compares less impressively with the vigorous income-bearers hitting the scene.

Investors will no longer pay as much for existing bonds, given their yields looks a bit skinny compared to the competition. Hence prices fall, until again yields are trading appropriately across the spectrum of bonds in issue.

See old Monevator articles from the attic for more on bond prices and yields.

Note that for very liquid government bonds, these fluctuations usually happen near instantaneously as the market’s perception about future interest rates changes all the time.

It’s kinda like a non-stop debutant’s ball, with the older bonds looking more or less lustrous versus the new generation, depending on how well nourished they are.

So far, so just-about-simple. But wait – don’t go calling Goldman Sachs just yet thinking you’re the next big thing in bond trading. There’s more!

The vast majority of government bonds are issued with a fixed lifespan, with the government promising to repay a particular tranche of bonds’ face value on some far-flung future date.

This date is indicated in the bond’s name.

For instance the UK Gilt Treasury 4.5% 2034 bond will be redeemed in 2034, which at the time of writing is just shy of 18 years away. Until then this particular bond will pay 4.5% a year (although as described above, the actual yield you’ll get from you bond will depend on the price you paid for it).

But here’s the bit that’s on the test as far as today’s article is concerned: The greater the number of coupon payments your bond has still to make until it matures, the more its price will fall or rise with interest rates.

That’s because a so-called long bond is stuck with its relative advantage or disadvantage for more years into the future than is the case with a short bond.

(A long bond is one where there’s a long time until it matures and is redeemed – at least ten years or more. A short bond is one that will mature in the next few years).

Duration and risk

The critical metric for this is called duration.

Your bond fund’s duration should be published on its factsheet. It tells you how susceptible the fund is to market interest rate changes.

The longer the maturity dates of the fund’s bond holdings – and the lower their coupons – the bigger the duration number. The bigger the duration number, the more volatile the fund.

In simple terms2 a duration of 23 means that if market interest rates go up 1% then the fund loses roughly 23% of its value.

Equally, if interest rates fall by 1% then the fund would gain roughly 23%.

And here’s the rub – the average duration figure of every UK linker fund available to DIY investors (whether passive or active) is in this risky high-duration ballpark.

To give just one example: Vanguard’s UK Inflation-Linked Gilt Index Fund has a duration of 23. Fully 80% of its holdings mature beyond the next ten years and its longest dated security matures in 2068!

I’ll be quite mature myself by then and only a few years short of my birthday telegram from King William V.

But, hey, these funds have been fine so far because market interest rates have trended down since the early 1980s. The rate falls mean linkers have climbed in price, enabling the L&G All Stocks Index Linked Gilt Index Trust to smash the FTSE All-Share over the last 10 years – bringing home an annualised return of 8.7% for the linkers compared to just 5.5% for the shares.

But there comes a point… the world and his wife is waiting for interest rates to rise again…

And while the world and his wife may not be right, if they are right then big capital losses in long-dated linker funds could render their inflation protection moot.

Which is a bummer, because the point of your bond asset allocation is to offer stability, not volatility.

How far could rates rise?

First of all it’s important to mention that these ‘market interest rates’ I keep going on about are not the same thing as the interest rate set by the Bank Of England, which is known (in a rare instance of clarity) as Bank Rate.

Rather, market interest rates refer to the going yields on the whole universe of bonds across the yield curve, reflecting the returns that investors demand for bearing the risk of holding any particular bond.

Market interest rates are strongly influenced by Bank Rate, to be sure. But they are also influenced by the interaction of supply and demand, market expectations on the economic outlook, the credit worthiness of the bond issuer, any particular bond’s maturity date, and more besides.

In other words if the Bank Of England jacks its interest rate up by 1% over the next few years, that doesn’t mean your fund with a duration of 23 will automatically lose 23% of its value.

What actually matters is the prevailing real yield. This is the annual average return investors demand for holding any particular tranche of linkers after accounting for inflation. This is the market interest rate we’re concerned with here and it’s historically been much higher than it is now.

The graph below plots the real yield from linkers3 since they were introduced in 1981. It’s our best clue as to where we might expect yields from linkers to be in ‘normal times’.

UK real yield

Source: Sarasin & Partners Compendium of Investment 20th Edition, p.37

As you can see, the real yield hasn’t sat above 2% since the early 2000s. Since then it has drilled deep into negative territory. It was around -1% at the end of 2015, and it’s been even lower since.

A return to a 2% real yield on linkers would see the value of a typical long duration bond fund plummet. This is why the risk ratings in linker fund KIIDs4 are as high as for most equity funds, despite UK government bonds being seen as a safer assets class than shares.

But don’t just take my word for it – listen to someone with skin in the game. Paul Rayner who manages Royal London’s UK Index Linked Government Bond fund counsels:

If inflation gets out of control, the Bank of England would have to react by pushing base rates up sooner and faster, meaning real yields would have to go up more.

Because you are in the longest-dated bonds, the real yield move would have offset any protection you had from inflation. You would actually lose money.

Rayner actually believes that long duration UK linker funds are more suited to pension funds than retail investors:

We really stress this when we talk to investors in the fund. Most inflation products out there are not inflation-protected bond funds but real yield funds.

With 19 years of duration, the biggest driver [of fund returns] is what happens to real yield, not inflation.

Distorted market

So look, this all sounds pretty grim, and almost like anyone with a linker fund in their portfolio might as well be on a long-haul flight with a time bomb in their suitcase.

However there’s no certainty that real yields on UK linkers will head north anytime soon.

Why? Because UK pension funds are on an all-you-can-eat linker binge that shows no signs of abating.

I could quote any number of institutions on this topic, but here’s just one view from global bond specialist Pimco:

Put simply, it is the seemingly insatiable demand from UK pension schemes that has pushed valuations to extreme levels.

These schemes feel they have no choice but to accept ever lower yields as they seek to immunise their inflation-linked liabilities.

In short, regulation has forced UK pension funds to explicitly link their liabilities to inflation. Whereas previously the industry earned high returns from equities, the closure of many schemes and their diminishing time horizon has prompted a shift to larger inflation-linked gilt allocations in order to reduce risk.

The resultant demand from the pension industry for linkers far outstrips government supply. Hence their yields have continued to fall.

The pension funds care more about controlling their risk than generating strong returns. While regulation can change and inflation-focused derivative products have been introduced to ease the logjam, asset managers Schroders believe that yields are stuck fast:

Pension funds waiting for index-linked gilt yields to rise to ‘attractive’ levels are fighting a losing battle.

The imbalance is structural and yields are likely to remain depressed relative to economic fundamentals for the foreseeable future.

Tectonic forces are at work in the UK linker market. Real yields have never been lower but a rapid and one-way rebound is not inevitable. Even then yields would have to rise faster than expected to catch the market out.

What’s the answer?

Even if a bloodbath is not inevitable, it’s pretty obvious by now that long duration linker funds are not the anti-inflation defence most of us are looking for.

So where else can we turn for inflation protection?

Your options are to invest in:

  • Short-dated UK linker funds with shorter durations.
  • A ladder of individual linkers (i.e. not a fund) that you hold to maturity.
  • Real assets like property, gold, or commodities that are famed for their inflation deflecting powers.

Let’s deal with each of these in turn (as quickly as possible, because that 2068 bond is in danger of maturing before this post ends!)

Short-dated UK linker funds

I can’t find any of these in the active or passive space that are suitable for us DIY passive investors.

True, there’s the Dimensional Sterling Inflation Linked Intermediate Duration Fixed Income Fund – which has a duration of 9.6 – but that’s only available through a Dimensional-approved financial advisor.

There’s also a St James’ Place Index Linked Gilt Unit Trust that also looks like an intermediate fund (duration isn’t given). But, again, that one doesn’t seem to be available beyond an approved network of financial advisors. Oh, and its Ongoing Charge is an eye-watering 1.2%.

If anyone knows of anything more suitable then please let us know in the comments below.

A linker ladder

This strategy is called a ladder because you buy a series of individual linkers with maturity dates that match your future spending needs.

For example, if you estimate your spending to be around £25,000 in 2026 (seriously!) then you’d buy enough of the linker that will mature in that year to cover you when it pays out. That’d be Treasury 0.125% Index-Linked 2026, then.

The amount that you’ll actually receive will be adjusted in line with RPI. This is why linkers are so valuable to anyone exposed to inflation risk, such as retirees.

The point is by holding your linkers to maturity, you can safely ignore any intervening capital losses (or gains) caused by interest rate movements because you are guaranteed a known payout (plus the inflation rate) on maturity.

With a ladder, the inflation protection works as advertised, except that there are frequent two year and occasional three year gaps between available maturity dates. Calculating income requirements for three years worth of inflation is negligible at current levels, but it will be less so if the money-munching inflation monster is on the loose and it’s wearing a 1970s-style kipper tie.

You’ll also have to accept buying inflation-protection in the current climate means buying into a negative real yield. You will be losing a percentage point or two every year in order to immunise yourself against the threat of unbridled inflation in the future.

That’s not necessarily a terrible bargain given the havoc inflation can wreak – and anyway, you won’t escape negative yields by buying equivalent nominal bonds or funds either, given their current paltry payouts.

But obviously it’s not going to turn you into Bridlington’s answer to Warren Buffett.

Rolling short-term linkers

Another thing you can do with your maturing linker ladder is to reinvest it… in more linkers.

Let’s say you invest your inflation-linked allocation in index-linked gilts covering the next five years. As each linker pays out income and eventually matures, you reinvest the proceeds into new linkers that mature further down the line.

For example, when your index-linked bond 2017 matures, you reinvest the proceeds into the 2022 issue to keep the ladder extended out to five years.

This is known as a rolling ladder, and it’s effectively a DIY short-term bond fund. Your rolling ladder will have relatively limited exposure to capital losses (if you were forced to sell for some reason) thanks to the shorter duration. But it’s also a lot less convenient than a bond fund, as you have to manage it yourself.

I haven’t worked out the platform / dealing fee implications, so I’m not saying “Do this!” But it is an option worthy of further research if you’re interested. (Please do share your comments below if it’s a strategy you’ve investigated or implemented).

Other real assets

Gold, commodities, property, and equities are all touted as assets that can protect you against inflation.

But while there is some truth to the claims, there is plenty of evidence to suggest that none of the above are truly good inflation hedges.

For example, while equity returns have beaten inflation over the long-term, they can be severely damaged by high inflation conditions over shorter timeframes. (Think the 1970s again.)

The chart below shows that only the returns of commodities, timber, and short-term linkers correlate particularly well with inflation in periods of three years and under.

Assets vs inflation

Source: Global Inflation-Linked Products, Barclays Capital, p.227

Does that sound half promising? Well, the author of the table goes on to say that the volatility of commodity returns make them a poor inflation defender across any time period, and that the short data sample is a strike against timber.

This is but one of many commentaries I’ve read warning against investing in commodities. And there are plenty more still that lay waste to the notion that gold returns bear any resemblance to inflation.

On the other hand, investing grandees William Bernstein and Jeremy Grantham have written about the potential of precious metal and natural resource commodity producers to put up a stiff fight against inflation.

It’s a whole other post really, so for now you can read Grantham’s take and make your own mind up.

Shorter duration global inflation linked bond funds

Okay, now these look like a good option for accumulators, so long as the fund’s returns are hedged back to Sterling to eliminate currency risk from the equation.

Global inflation-linked funds invest in linkers from other developed world countries (not emerging markets) with the bulk coming from the US while the long tail is made up of France, Italy, Germany, Canada, Japan, the ANZACs and others.

The shorter durations of these funds mean less exposure to volatility should interest rates spike. The trick is to hold funds with a duration that matches or undershoots your time horizon.

Developed world inflation rates are related to each other (first cousins perhaps) but aren’t dead ringers. For instance here’s US CPI vs UK RPI over the last 50 years:

UK RPI vs US CPI

The two measures bear a resemblance, but UK RPI has been wilder at times. For this reason, if I was a retiree in need of precision inflation protection I’d think linker ladders first.

But as accumulators, most of us have time to ride out inflation – we’re more interested in diversification across asset classes.

In this scenario, global linkers can make a positive difference:

  • They have a relatively low correlation with other asset classes.
  • They offer a positive return but with less volatility than domestic linker bonds as interest rate movements across multiple markets mitigate financial shocks in any one country.
  • Higher inflation countries (hello UK) could benefit from a so-called ‘positive carry’ on the currency hedge, which could lower the mismatch in inflation rates over the medium term.

One among a number of sources extolling the virtues of global linkers is Barclays Capital. In its Global Inflation-Linked Products – A User’s Guide, the bank writes:

A currency-hedged global linker portfolio maintains the most attractive features of a domestic inflation-linked bond portfolio, specifically: better diversification, enhanced returns and low risk.

However, global inflation-linked bonds add a further diversification benefit to a portfolio, even if this already includes domestic inflation-linked bonds, leading us to see a global linker portfolio as the best way to capture the strategic benefits of owning linkers.

Both Tim Hale and Monevator’s own Lars Kroijer have global linkers on their list of acceptable assets, too.

Bear in mind that you shouldn’t have to pay tax on the inflation uplift received on income from index-linked gilts (assuming your fund is based in the UK). This is not the case for global linkers, so it could well be worth stashing them in your tax shelters.

There are a few Sterling hedged global inflation-linked products that are worth a look, although I have to say none look like my dream fund.

In the passive camp we have:

L&G Global Inflation Linked Bond Index I

  • OCF 0.27%
  • Duration – not given. Perhaps around 11 – 13? Contact L&G to find out for sure.
  • The fund holds 11% BBB rated linkers, which are below the UK’s AA- credit quality but still investment grade (just).

db X-trackers iBoxx Global Inflation Linked ETF

  • OCF 0.25%
  • Duration is 13.
  • The index is composed of 8% BBB rated linkers.
  • It’s a synthetic ETF.

Okay, well that’s the end of the passive contenders. With the choice is scarce so on this occasion – and with a clothes peg on my nose – I’m prepared to look over the active side of the fence:

Standard Life Investments Short Duration Global Index Linked Bond Fund

  • OCF 0.68% (Expensive!)
  • Duration not published – I judge around 9, but check.
  • Only 70% of holdings are actually inflation linked, 6% are corporate bonds, 2% are BBB.
  • 29% in UK bonds.
  • Active fund.

Royal London Short Duration Global Index Linked Bond Fund

  • OCF 0.33%
  • Duration is given as 5 in the brochure.
  • Only launched in February 2016 and info is scarce. There’s not so much as a factsheet available. I’d hold off until they reveal more.
  • 21% in UK bonds.
  • Active fund.

And that’s your lot, unless you know better? Again, please share your fund finds in the comments below.

Extra mature

Well, I don’t know about you but this post has certainly aged me. And if interest rates do jump up on those long-duration linker funds then I’ll probably add a few more grey hairs still.

How I wish the Government would release more NS&I index-linked certificates. They truly are the ideal antidote to the problem of inflation for small investors.

In the meantime, as a result of my latest research I now plan to pare back the allocation to linker funds in Monevator’s Slow & Steady portfolio to no more than 25% of its bond holdings. Perhaps less. I’m keeping them only as a diversifier as they are relatively uncorrelated with other asset classes.

The remainder of the linker asset allocation will go to a shorter duration global index-linked fund, which offers some inflation proofing and more diversification for the portfolio.

For retirees or near retirees, a linker ladder or inflation-linked annuity (as expensive as those options look) seem like a better bet. A small dose of commodity producer equities may warrant further investigation, if you can buy them cheaply.

Few areas in investing life are more important than inflation protection – I’m only sorry the options aren’t more comforting. As ever, we’ll just have to do the best we can.

The problem with low interest rates

A spaceman floating through space representing how low interest rates may have taken away the gravity from investing.

Very low interest rates have been with us for nearly a decade. There are strong arguments to justify their use.

But that doesn’t mean we have to like them.

In trying to address various ills, low interest rates may cause their own problems. I think there are signs that politicians and central bankers are getting more concerned about these downsides.

Prompted by readers, I’ve looked before at how and why rates got so low. Today we’ll consider the fallout.

Let’s keep things simple. This is a thorny issue, and as prone to myths and crank theories as, say, gold. Often from the same people!

So for the record I don’t think low interest rates are a conspiracy to defraud the middle-classes.

Nor do I think central bankers are stupid or crooked. (They may be prone to hubris.)

Whisked forward in a time machine, I suspect 2009’s central bankers would be surprised to find rates still at 0.5% or lower in the UK, the US, and Europe.

But what else were central bankers to do? With low rates and quantitative easing (QE), they’ve used a limited tool set to salve battered economies.

Elsewhere political leadership has been notable by its absence. Regulators have often made things worse.

Outside of London house prices, there’s been little sign of inflation. There have even been deflationary scares. It’s not like bankers kept rates low in an overheating economy.

So I’m not going to rant about the motives of central bankers.

Instead let’s take a tour of the problems the low rate strategy may have caused, and that may prompt a rethink.

The lowdown on rates

If you’re under 25, you might wonder what I’m on about when I say ‘low interest rates’.

Aren’t interest rates always close to zero? Am I thinking of how the Bank of England recently halved its rate to 0.25%?

We need to look further back that that.

It is true rates have had an inferiority complex for years since the financial crisis.

But as recently as 2007 you could still get 5% on your cash savings – and much more if you shopped around.

Also, this topic goes further than the rates paid by High Street banks.

In part one we saw how central bank rates influence the yields on investments such as government and corporate bonds.

But investors who buy and sell such bonds on the open market also influence their yield.

Remember how to calculate yields? As investors bid up the prices of bonds their yields fall, and vice versa. So bond yields are set by supply and demand from the whole market.

Now here I’m already straying into disputed territory.

Those who doubt the efficacy of today’s bond market point to central bank manipulation. Central banks have bought huge quantities of government bonds through their QE programmes. They are distorting prices and yields.

Indeed, the point of QE is to lower market yields!

You can see how UK government bond yields have collapsed in this graph:

UK real yield

Source: Sarasin & Partners Compendium of Investment 20th Edition, p.37

In Europe, Japan, and the UK, central banks have even started buying corporate bonds. (In Japan they’re buying equities!)

All this central bank buying does complicate talk about market-driven rates.

But pension funds and commercial banks do influence yields through their trading activities. Central bank rate setting and bond buying is only part of the picture. (Albeit a bit like a cartoon of an 800-pound gorilla sprayed onto a Gainsborough by Banksy).

Yields would rise if the bond market revolted against central banks and stopped buying. It’s hard to buck central banks, but it’s not impossible if their actions are at odds with reality.

So in buying and holding low-yielding bonds over the past few years, investors may be agreeing that low rates are appropriate.

On the other hand, banks, pension funds, and others don’t have much choice about government bonds. They’re required to hold them for regulatory reasons.

They also knew central banks would be big, price insensitive buyers. Whatever their own views about the wisdom of high prices and low yields, it might have made sense to buy anyway.

I don’t want to go too deep into the weeds here. Just know that all kinds of buyers and sellers – both domestic and foreign – influence bond yields.

Central banks respond to these yields, as well as looking to influence them.

10 problems with today’s low interest rates

In part one I featured a graph tracing 5,000 years of ups and downs in interest rates. Much of that chart was guesswork.

We can be surer of recent history. Bond prices and yields represent the wisdom of uncounted bankers, traders, and investors. At $100 trillion, the global bond market is bigger and deeper than the stock market. Its gyrations are well documented.

(Passive investors who wouldn’t dream of timing the stock market seem happy to take a view on bonds. At least know what you’re betting against!)

Here’s a graph of government bond yields over a (shorter) long-term:

A century and a bit of global government bond yields.

A century and a bit of global government bond yields.

Source: Deutsche Bank

You can see government bond yields in the advanced nations are at historic lows. Whatever this situation we’re in represents, it’s unprecedented.

Let’s consider some of the potential problems it may be causing.

1. Savers are not rewarded

Some question the moral overtones of casting savers as the good guys and debtors as the bad. But most of us believe prudent saving is the more responsible choice.

Yet consider the lessons of the past 10 years.

Low rates hit savers hard. But they enriched those in debt – whether companies, spendthrifts, or mortgage holders.

Meanwhile lifelong pension savers faced plummeting quotes when they came to buy an annuity.

The pension freedoms that sought to address this were welcome. But many pensioners would have preferred a safe and reasonable regular income.

As for cash, banks have slashed the rates of even their best savings accounts to below 0.25%.

The Sunday Times recently reported that customers with less than £25,000 in their Natwest cash ISA get a rate of 0.01%.

Invest the full £15,240 at the start of the year in that ISA and you’ll make £1.52 in interest.

Save monthly and you’ll earn 83p!

The financial crisis was all about reckless lending and borrowing.

Has the decade of near-zero interest rates that followed it educated people to save or to spend?

2. Hard to generate a risk-free real return on capital

The lack of a return on cash and other safe assets isn’t a case of money illusion.

Money illusion refers to how we tend to think of currency in nominal rather than real1 terms.

When we look back at the higher returns from cash in the past, we may forget that inflation was also higher.

But this tendency doesn’t excuse away today’s lousy returns from cash.

Yes, inflation is low. But interest is nearly non-existent.

This graph isn’t the clearest, unfortunately. But squint and you’ll see how real interest rates turned negative around 2009:

Real interest rates are negative in the UK.

Real interest rates are negative in the UK.

Source: World Bank data.

Negative real interest rates mean your cash shrinks in value every year.

True, there are various ways to eek out a higher return. You can use regular savings accounts or current accounts with various hurdles. Peer-to-peer lending offers higher returns, but they come with much more risk.

The safe quirky cash options don’t scale. Anyway, the World Bank data above shows the average rate earned on cash. Whatever you’re doing, most people aren’t moving cash around the best accounts. Their cash is languishing in accounts that erode its spending power.

This relentless shrinking is not normal. The long-term real return from cash is about 1%2.

That’s not massive, but it was something.

For government bonds, the picture is more complicated.

The long-term average real return on UK gilts was 1.3% over the past 116 years3. But investors did much better in recent decades than history or theory would suggest.

UK government bonds actually beat shares over some lengthy periods ending in recent years. Such long-term out-performance makes no sense given bonds are much safer than shares.

So what happened?

As interest rates plunged, bond prices soared. This delivered high capital gains, which for long-term holders made up for shrinking yields.

A 10-year government bond today sports a yield to maturity of around 1%. In contrast, when the FTSE 100 first breached 7,000 at the turn of the century, the same bond paid 6%.

The investing world has been inverted. UK investors now buy equities for income and have seen capital gains from their bonds.

But the Bank of England expects inflation to head above 2% in the coming years.

Buying a 10-year government bond today seems to all but guarantee a negative real return.

3. People may save too much

There’s actually not much sign of this – savings rates in the US and the UK have been trending lower.

But in theory, if people don’t believe today’s low yields will growth their wealth enough, they may compensate by saving more.

That’s fine on an individual level. (In fact I was encouraging it just the other day here on Monevator).

But if you’re a central banker implementing low rates, it is counter-productive. You’re trying to get money moving again through the economy.

It’s worth saying that the household savings ratios are so broad they might not give us a true picture here.

4. People nudged into unsuitable or too-risky investments

Interest rates are puny. Locking in a 1% bond yield is about as attractive as buying a timeshare in a termite-infested tree house.

Many investors have instead sought higher returns. They’ve bought corporate and high yield bonds, property, shares, and other assets.

They have ‘moved along the yield curve’, in other words.

This may well have been prudent – and it’s what central banks have been trying to get us to do. In theory it means less money sitting in cash and more money invested in more productive assets.

Yet with those higher potential returns come greater risks. This is true, whatever your motivation for seeking yield.

The following graph shows how riskiness increases as potential returns increase.

As we move into riskier investments (X-axis) returns increase (Y-axis).

As we move into riskier investments (x-axis), potential returns increase (y-axis).

Imagine we now pull down the left hand end of the curve. We do this to reflect how the returns from cash today are near zero and bonds not much better.

In response, teed-off investors move along the curve seeking higher returns. As they do so their incoming money bids up the price of assets and pulls down yields.

Probable returns fall all along the yield curve. But the relative riskiness of the different assets doesn’t change:

The grey line represents how likely returns are lowered across the yield curve.

The grey line represents how likely returns are lowered across the yield curve.

Readers tell me they’re putting all their money in shares because cash pays “nothing” and bonds are “guaranteed to lose money”.

If you hold more shares because you can’t stand the prospect of a 1% yield to maturity from gilts, I think that’s understandable. I’m similar.

But you must do so understanding shares are still riskier. They can still crash 50%. And their returns will likely be lower than in a world where bonds were yielding say 4-6%.

Ignoring this is what we mean when we say low interest rates may have encouraged people to take on too much risk.

5. Low rates can also encourage bad investments by businesses

It’s not just you and me finding it hard to make profitable investments these days.

Slow economies and low inflation makes it hard for companies to make good returns on capital.

One solution is to use cheap debt to juice up the lowly returns from a ho-hum investment.

I won’t go into the maths here. Suffice to say a project that delivers a 6% return on capital is more exciting when funded with debt costing 3%.

This is one of those It’s Complicated issues. But the summary is a lot of low-quality debt-fueled expansion may be taking place.

Some believe companies’ enthusiasm to buy back shares and pay dividends despite low growth may be part of this phenomenon, too.

The FTSE 100 saw its total dividend payout uncovered by earnings in the early months of this year. That hardly fills one with confidence.

(I suspect the post-Brexit weakness of the pound might have boosted foreign earnings enough to plug the gap for now).

6. Dampens creative destruction, and curbs productivity

Low interest rates mean some indebted companies that would have gone bust don’t. Instead they limp along meeting the low interest payments on their debts.

So what? It’s rare anyone high-fives news of a company closing down.

So what? It’s rare anyone high-fives news of a company closing down. Many are aghast at a retail chain closing or a steelworks shuttering due to the job losses.

Well, such closures are grim for those individuals involved. But from a macro-economic perspective, it’s vital bad businesses fail.

We want capital to flow to the better companies – those that have discovered more efficient ways to deliver the goods and services we need. This is how productivity and innovation improves all our living standards. It’s also how capitalism rewards entrepreneurs and investors for their risk taking.

Zombie companies clinging to markets, facilities, employees, and capital slow down creative destruction. This is one way low interest rates could be prolonging slow growth in the developed world.

It was worth avoiding a global depression in the wake of the financial crisis through low rates.

But do we want to drag the pain on for decades?

7. Banks find it harder to make money through normal banking

Fair warning. Whether low interest rates hurt bank profits – and zero interest rates flatten them – is a thorny topic.

Indeed if there’s a Fight Club where analysts go to let of steam, then this is the topic that gets them pumped up.

“You see that punk over there? He thinks all that matters is a bank’s net interest margin. He says this can move up and down regardless of the level of market interest rates. I hope you’re going to hit him where the QE don’t shine!”

I’ve grappled with this in my own stock picking. Resolving the debate is well beyond the scope of this article.

Suffice to say that if you want to know what the market thinks about it, look at US bank share prices. They go up when it seems the US Federal Reserve is about to raise rates, and they slump when it doesn’t.

Let’s say for the sake of argument that low rates do hurt bank profits. Again, you might argue, who cares? Nobody likes a banker these days, right?

But it’s a bit like the waste pipes heading out of your lavatory. You might not like to think about it, but banking is the economy’s plumbing. All kinds of bad things might happen if normal banking profits aren’t possible.

For instance, banks might hoard capital instead of lending it into the economy. This could undo the easing efforts of central bankers. They might only invest in super-safe prospects, taking us back to slowing productivity. Or they may try to make more money through opaque means, such as unreasonable fees or similar. (PPI shows us this is nothing new!)

If banking is broken, more money might flow into the so-called shadow banking system, or into peer-to-peer lending. These areas are not be so well regulated. Their growth could introduce instability into the financial system.

Let’s not forget the low rate policy began with trying to restore financial stability. If banks can’t make profits – if they struggle to attract capital – they can become a source of instability. Successive waves of drama on the continent have demonstrated that.

To show my hand, I have a hunch central bankers worry about bank profitability. I think this may be what reverses the march into zero interest rates. When the ECB last cut rates, it included measures to support bank profitability. It wouldn’t have included them if it had no concerns. There are signs that Japan’s central bankers may be reaching the same conclusion.

8. Insurers find it hard to make money

This one is a bit more obscure, but it could prove relevant if low rates persist for a long time.

If insurers can’t make an adequate return from the bonds they must invest in, then they may withdraw from the market. Alternatively, they may introduce charges that make their products bad deals.

Teetering insurers would not be good for financial stability any more than shaky banks.

But there’s another issue.

If insurers can’t provide the services we need, we might decide to self-insure instead.

This takes us back to that potential for excessive savings. It’s also inefficient. It’s more burdensome to insure your own liabilities (or those of your company) when the costs and risks are not widely shared. Insuring your health, life, and property more efficiently is one of the benefits of capitalism.

9. Pension deficits are skyrocketing

On a related note, low yields are causing big headaches for pension funds.

Low yields make it hard for pension funds to match their assets to their future liabilities.

If real terms payouts from bonds are low, then a scheme’s investment in bonds won’t go so far in meeting the payouts promised to pensioners.

This problem reached its apex when gilts soared (and hence yields fell) in the wake of Brexit.

As The Telegraph reported:

“Britain’s generous defined benefit pensions have plumbed further depths during August, reaching another record-breaking deficit of £459.4bn as the scramble for bond assets and the interest rate cut sent their liabilities soaring […]

“A rush for safe-haven bonds around the world has sent the yields on sovereign bonds through the floor – meaning a fall in the regular income that pension funds use to pay their retirees their defined benefits, sometimes known as final salary pensions.

The Bank of England’s rate cut to 0.25pc has worsened the shortfall.”

As I’ve said, I don’t believe low yields are due to central bankers alone.

Factors such as regulation, demographics, technology, and globalisation are in the mix. Yields were falling before the crisis, and pension deficits are nothing new.

But I do think the low rate strategy of central banks has put the boot in. To the extent that the policy may be up for a rethink, pension schemes in crisis seems a likely motivation.

10. Makes it hard to value other assets

This article is a monster, and this final point could amount to a series of articles in itself.

So I’ll be brief. Low interest rates may be influencing – or distorting – the valuations of all assets.

This is not just because of the “reach for yield” I discussed above.

It may be rational for a given investor to pay more for an office block, a factory – or a global tracker fund– when rates look likely to stay lower for longer.

But a further problem may arise from plugging low yields into asset valuation models.

Discounted cash flow models try to estimate the cash due from a company or property. They then compare this to the yield you could get from the lowest risk asset – a government bond.

Plug a historically low risk-free rate into such a model and you can get extreme valuations. It’s possible to argue that everything from shares to housing is cheap.

This would strike many people as pretty odd. Other metrics suggest valuations are at least fair. And instinctively we doubt that low interest rates will persist.

Yet there could be even deeper problems.

As the name suggests, a discounted cash flow model puts a discount on the future cash due. This reflects the uncertainty about future profits, as well as inflation and interest rates.

Normally, distant payouts are deeply discounted. But with the risk-free rate so low that doesn’t happen so much.

Why does this matter?

Because uncertain future forecasts have grown in importance compared to near-term cash flows. A discount rate of 2% doesn’t have much impact until you get far out.

This makes the present value of an asset even harder than usual to determine with confidence. Because future cash flows assume greater importance, the valuation is based on more finger-in-the-air guesswork.

It’s a nerdy-sounding but important point that may mean market valuations are wildly off. Even a modest rise in rates could cause a crash in all sorts of assets beyond what we’d expect.

Or it might not. Markets are not stupid, and they may have taken this into account. Time will tell.

Conclusion

I hope this long romp gives those who asked for it an idea of the problems low interest rates may cause.

How will they be unwound – and what are the consequences for our portfolios? That’s the $100 trillion question.

I stressed in part one that people have got egg on their faces for years trying to call the top of the bond market. (That is to say, the bottom for yields).

But I hope it’s clear that if yields do rise sharply, a fall in the value of your government bond fund could be your least concern.

If there is a bond bubble, it’s probably also reflected in equity, property, and other markets.

So swapping all your bonds for shares might be a case of jumping out of the frying pan and into the fire.

Then again, the long-term potential from shares, say, does look much better than from bonds. Government bonds are on historically tiny yields, which point to low future returns.

But you must buy shares knowing you have the stomach to endure steep stock market crashes. If you can accept that, equities may be much better value than bonds.

A diversified portfolio will be the best pragmatic response for most. That means owning cash, bonds, global equities, commercial property, and perhaps some gold.

‘Hero’ bets on one asset or another make for good articles and spunky anonymous blog comments. But we’re deep into unknown territory and we may be at a turning point if central bankers are having a rethink.

I think a bit of humility might be a wise investment.

Weekend reading: Screw it, let’s not do it

Weekend reading logo

Good reads from around the Web.

The national disaster that is Brexit keeps delivering. This week’s barrel-scraper was outrage at a High Court ruling that Parliament must be allowed a vote before the UK can start to leave the EU.

Remember: The high-minded veneer grafted onto the murky motivation for Brexit was we must ‘take back control’ from Europe and follow our own laws.

Yet when a British court says what the British law is, the judges are called “enemies of the people” by the Daily Mail.

daily-mail-cover

The Mail has been on the wrong side of history for 100 years, so no great surprise there.1

But the rest of the right-wing press also panted with fury at British law being ruled upon by British judges.

And this being Brexit, there was further nastiness.

The MailOnline was outraged at the ruling from an “openly gay” judge in repeated references it has since removed (after a backlash).

Meanwhile The Sun highlighted how some of those who brought the case to court were foreign-born.

Not that Brexit has anything to do with intolerance and xenophobia, you understand.

Let’s get elitist on their ass

I’ve had enough of this nonsense, and of arguing with Leave voters. Nine out of ten of the vocal ones online are angry and incoherent. Their vitriolic response to the High Court ruling puts me in a counter-revolutionary mood.

Can we not call the whole thing off, and leave these people to go back to shouting at cyclists?

We’re often told Brexit was a kick out against the globe-trotting London elite who run the country for their benefit.

If that’s true, then isn’t it time we pressed the Elite Mode cheat button?

Of course some Leave voters will be upset if we cancel Brexit:

  • Sovereignty-minded Leavers – By far the most respectable Brexiteers, they would be legitimately aggrieved by us wriggling out of Brexit. The hypocritical response to the High Court ruling does curb my sympathy, however.
  • Provincial protest voters – Would be angry, but I believe they’ve shot themselves in the foot with their protest vote. Brexit won’t help them.
  • Grumpy old men – Barry Blimp will be angry whatever we do. No Brexit will go far enough for him, he’d need a time machine for that. Calling off Brexit will give him something to moan about forever, besides climate change and women doing the football commentary.
  • Free-trade zealots – The vision of a Singapore-styled Britain as a privateer on the global seas of capital is sunk if we stay in the EU. But few voters want it, anyway.
  • Anti-immigration voters – Unlike some, I don’t call all these people automatically racist. Britain isn’t the biggest country in the world, there are pressures on our housing and services, and transnational migration isn’t going away. However on balance I don’t think pulling up the drawbridge unilaterally via Brexit is the best solution. Perhaps we could leverage our not leaving into a rethink on 100%-free movement?
  • Racists – Brexit won’t be enough for them.
  • Numpties – Maybe we could send them their old-fashioned blue British passports and just pretend we’d done a Brexit?
  • Pensioners – The statistics show the older you are, the more likely you voted to Leave. Drag the exit out for long enough and this problem goes away. Clever young people can then return to thinking about where in a continent of 500 million people they might want to find the love of their lives, make their home and their livelihood, and all the rest of an inheritance that’s being thrown away by Brexit.

I had a dream

Sadly, I think we will almost certainly enact some sort of Brexit. A few politicians will make principled resignations, but most blow with the wind. Populism is in the air, and even many Remain voters who were as dismayed as me about the referendum result would be aghast at it being blatantly disregarded.

Well, respect. I guess that’s the price you pay for being more reasonable than your opponents.

Just maybe though, the High Court decision could be the start of throwing enough grit into the wheels that we can trundle towards a softly softly Brexit, as opposed to the hard exit the government seems hellbent on accelerating into.

The markets appear slightly more optimistic. UK-focused shares such as banks and housebuilders soared after the High Court ruling, as rumours of their demise suddenly seemed premature. The pound rallied a tad too. There are even calls for an early General Election. (One it’s unlikely an anti-Brexit coalition would win, unfortunately, especially with Labour in such a shambles.)

I was totally wrong about the immediate impact of Brexit on the economy. Uncertainty is almost always bad news, but so far that hasn’t held (perhaps because we were doing even better than I thought before the vote, despite, you know, being “shackled” to Europe… And of course there has been the short-term boost from the Brexit-weakened pound).

But I’ve not changed my medium to long-term view that any hard Brexit would be a bad outcome for most.2 As for the social downsides, they’re escalating.

The Brexit train has left the station, but we don’t have to drive it off a cliff.

Mob handed

Were I to allow them the opportunity (I’m pretty busy this weekend, so won’t) I’d get plenty of vitriol from certain Leave voters for this post.

This despite Monevator being a personal blog, and my commentary being far milder than the rhetoric I’ve cited from national newspapers selling millions and claiming objectivity.

Of course, I’d expect a rebuttal to any suggestion we might simply note and move on from the Referendum result. That would be fair enough. It’s the frothing and foaming that isn’t.

From The Guardian:

Former ministers warned that the febrile tone of media coverage […] risked poisoning public debate.

Dominic Grieve, the Conservative former attorney general, said reading hostile coverage in the Mail and the Daily Telegraph “started to make one think that one was living in Robert Mugabe’s Zimbabwe … I think there’s a danger of a sort of mob psyche developing – and mature democracies should take sensible steps to avoid that”.

Labour also raised concerns about the absence of a ministerial response to the media coverage.

Lord Falconer, who was lord chancellor under Labour between 2003 and 2007, said faith in the “independence and quality” of the judiciary was being undermined “by this Brexit-inspired media vitriol” in an article written for the Guardian.

Those who are quick to laud the will of ‘the people’ and wave the populist flag should at least be acquainted with the Reign of Terror, Gaius Marius and the fall of the Roman Republic, Yellow Journalism, and, well, the obvious.

And who knows, maybe the next President of the United States.

Weekend reading: Beat the market by saving more

Weekend reading: Beat the market by saving more post image

Good reads from around the Web.

The US investment advisory firm Research Affiliates made headlines this week when it predicted that American savers have a 0% chance of hitting their desired 5% or greater annual returns from a standard 60/40 portfolio over the next decade.

From Bloomberg:

Research Affiliates’ forecasts for the stock market rely on the cyclically adjusted price-earnings ratio, known as the CAPE or Shiller P/E.

It looks at P/Es over 10 years, rather than one, to account for volatility and short-term considerations, among other things.

Research Affiliates is a respectable outfit, but I’m not convinced that anything that spits out a ‘zero’ probability for investment returns should be taken as gospel. (I’m also somewhat skeptical of the utility of CAPE these days, but that’s for another article.)

What I’m sure of is that trying to do better by investing in active funds will serve most US thrill seekers poorly.

Yet as markets have climbed that has been the industry’s siren call (even as the data piles up showing ever more money ignoring them and migrating to passive funds).

Don’t beat yourself up

Remember, active investing at the stockpicking level is a zero sum game.

It’s true in theory that particularly perspicacious managers could sell out of some markets and move into others and generally juggle assets to receive better than 5% returns, but the evidence is very slim – well, non-existent – that more than a handful will manage it.

So the odds your chosen active manager will be one of the few are extremely poor.

By way of illustration, the average hedge fund returned just 0.7% in the decade ending 2014. Indexing guru Larry Swedroe has pointed out that means they under-performed every single major equity and bond asset class in existence.

Josh Brown at The Reformed Broker offered his usual robust retort to the chatter from active managers who claim passive investing “sheep” are about to be slaughtered:

If you’re a purveyor of high-cost, high-tax, high-transaction, high-bullshit, wannabe macro-genius strategies, you might want to look into the things you have so much to say about before mocking others who are doing the best they can to save and invest rationally.

You’re either pretending not to understand this in an attempt to mislead others or you’re genuinely uninformed yourself.

Save the day by saving more

As a long post by the robo-adviser Betterment spells out, the rational approach to low expected returns is not to try to find the next Warren Buffett, but rather to save more money.

It says doing better than average by even 1% a year through investing returns would require a fund investor to pick one of the one-in-three funds that beat the market in a particular year, and then successfully do it again and again for the next 10 years.

For those for whom maths is not a strong suite, let’s just say the odds of achieving that are not worth discussing further.

On the other hand, saving more is guaranteed to boost your final pot, compared to if you’d spent the money instead.

In their worked example, increasing the savings rate by just 8.5% delivered the same outcome as achieving that wildly improbable run of annually switching your money from winners to winners for a decade.

Same difference

Remember, these people are all commenting on the US market. I think our stock market looks cheaper personally and our bond market more stretched – but as always what do I know.

Anyway, many sensible passive investors are in world market trackers these days, and they are massively weighted towards the US market. So the outlook is relevant.

The bottom line is saving a few more quid probably isn’t going to hurt. The alternative responses might well do.
