For a long time we couldn’t compare the rates of interest on cash in investment accounts for one simple reason.

Brokers weren’t paying any interest on cash!

Rising rates have so dominated the news for the past 18 months that it’s easy to forget that interest rates were near-zero for more than a decade.

Even savings accounts at your bank paid no interest. So your online broker1 was more likely to send you a Christmas hamper from Fortnum and Mason than to cough up interest.

But now the Bank of England’s rate is 5% and everyone is giddy about cash again. (Let’s leave aside the fact that inflation in the UK is still nearly 9%…)

As a consequence, many investment accounts do now pay some interest.

Not all of them, not always very much, and it’s often difficult to find out exactly what interest rate they are paying – but it’s better than nothing.

You still won’t find these interest rates featured in our broker comparison table though.

You can blame the platforms for that.

(Don’t) show me the money

It’s easy to point the finger at faceless corporations for making life hard for the little guy.

And believe me, I have been blaming not them but my co-blogger The Accumulator for the past few months for the lack of an interest rate column in our table.

“Let’s include interest on cash in investment accounts in our broker table,” I intoned from my lofty throne, like Zeus commanding the lesser gods to do his bidding.

The Accumulator looked up.

“Um, that’s an interesting idea *cough* something *cough*,” he said, before going back to doing whatever he wanted to do as usual.

This time The Accumulator was engrossed in a couple of months of deep-diving into commodity correlations.

What a thrill-seeking hedonist, I snorted. Why can’t he simply collate the interest paid on cash in investment accounts with the rest of the data he trawls to keep our table updated?

“Fine! I’ll do it myself!” I harrumphed.

Yeah that was a stupid idea.

The Accumulator is a platform maven. My co-blogger navigates the Byzantine information silos that pass for a broker’s help pages like a spaniel sniffing for truffles.

So at the least he would have confirmed the woeful job some platforms do of highlighting their rates of interest on investment accounts much quicker than I did.

But I don’t think he would have found all the data. In fact I suspect he knew this was a Sisyphean nightmare – hence his evasive action.

And so even as Monevator readers too called for rate data to be included in our modestly famous comparison guide, The Accumulator bumped around in his fat-suit, plotting lean hog futures against corporate bonds and keeping his head down.

Interest on cash in investment accounts at a few platforms

Maybe you’re thinking that this is where I’ll reveal that – after a week spent combing the platforms, calling their service desks, and meeting their hired representatives in the shadows of Canary Wharf – I’ll now unveil a comprehensive guide to interest rates at every broker out there?

Reader, your faith is touching.

But unfortunately I ran out of puff.

For example I spent half an hour digging around Lloyds Banking Group’s website to no avail. Both when navigating its own menus and when swooping in over the walls with a targeted Google raid.

At the time of writing I still don’t know if Lloyds pays interest on investor cash! Perhaps I’m missing something obvious but the information has eluded me.

At least its High Street rival Barclays clearly states it pays no interest on cash in investment accounts. And it only took me a couple of minutes to find that out.

It was similarly hit and miss with the other platforms.

Maybe this isn’t entirely nefarious obfuscation on certain platforms’ part. I get the impression today’s much higher interest rates have caught some platforms on the hop, like they have the rest of us.

Remember how Vanguard seemed to almost accidentally be paying a high interest rate earlier this year? And then how it at least appeared to revise the rate down when we noticed?

It could be a factor, but remember that uninvested cash left lying around in customers’ accounts is a profit center for most financial services companies. Pooled together, it can earn a decent chunk of interest that boosts their bottom line – at the expense of our own.

So they do have business reasons not to want their customers thinking too hard about interest.

Okay, now show us the money

Just to complicate matters, most of the platforms that do pay interest will give you a different rate depending on how much cash you have on their platform.

Which clearly makes doing any side-by-side comparison even trickier.

So for now I’ll just post a taster comparison. Focusing shamelessly on those platforms who offer us an affiliate fee should anyone sign-up, as compensation for my suffering.

But we will revisit and expand this table in a few months when – like a mother who gets broody again after she’s forgotten the experience of child birth – I have forgotten the pain.

Note: Rates are changing frequently. These are the latest as I write.

Examples of rates of cash on investment accounts: ISAs

As I discuss below, big gobs of cash should really be held in a cash ISA. But here’s what you’ll get with a few different investing platforms with a share ISA.

Platform	Interest rates (range)	Notes
AJ Bell	1.7% to 2.2%	Better rate is above £10,000
Bestinvest	4.1%	High rate on all accounts
Dodl by AJ Bell	0%	Free dealing quid pro quo?
Hargreaves Lansdown	2.5% to 3.5%	Four tiers up to £100,000+
Interactive Investor	1.5% to 3.5%	Three tiers up to £100,000+
InvestEngine	0%	Free dealing quid pro quo?
Plum	2.99% to 3.82%	Higher with premium plans, cash must be moved into ‘pocket’

Examples of rates of cash on investment accounts: SIPPs

Rates of interest on cash held in pensions are generally a little higher. That’s good, given the difficulty of accessing or moving money held in a SIPP.

Platform	Interest rates (range)	Notes
AJ Bell	2.95% to 3.45%	Better rate is above £10,000
Bestinvest	4.1%	High rate on all accounts
Dodl by AJ Bell	0%	Free dealing quid pro quo?
Hargreaves Lansdown	3.2% to 4%	Tiered, higher in drawdown
Interactive Investor	2.25% to 3.5%	Three tiers up to £100,000+
InvestEngine	n/a	Doesn’t offer SIPPs yet
Plum	2.99% to 3.82%	Higher with premium plans, cash must be moved into ‘pocket’

Where else to stash your cash

Excuse me for stating the obvious, but you don’t need to have your portfolio’s cash allocation kept in an investment account with your broker.

You’ll generally earn better interest elsewhere.

Cash can just accidentally accumulate with your broker, of course. Especially if you’re an active investor or you own a lot of income funds without dividend reinvestment switched-on.

But I also see people holding cash with their brokers as a result of mental accounting.

They think “I have £200,000 in my stocks and shares ISAs and I want some of that in cash as a safety cushion”.

Really they’d be better off holding that cash elsewhere and thinking of their assets holistically.

Sometimes you may have a good reason to hold cash in an investment account.

Perhaps you’re building up dividends for a particular purchase, or maybe you’re a naughty active investor indulging in a bit of (ill-advised) market timing. Or you’ll hold cash in your pension because you reason that adding to that bucket has special constraints – yet you want to really dial down the risk.

Still, the rate of interest on cash in investment accounts is so low that it is unlikely to be your best choice on even a short-term time horizon.

On a longer timescale it will cost you for sure.

So where should you be parking your cash for the longer-term?

Cash ISAs and savings accounts

You can get a much higher rate of interest with cash ISAs and standard savings than at your broker.

In an ideal world any strategic cash allocation – held say as part of a Permanent Portfolio-style plan – would be nestled inside a cash ISA, where it can grow unmolested by HMRC.

With interest rates now half-decent, beware that you won’t need a vast balance in a non-tax-sheltered saving account before you’ll be paying tax on interest.

Anyway, just don’t make the mistake of thinking you need cash in the same account as your shares or similar. Think holistically about your investing (and your net worth for that matter).

I do this via a master spreadsheet. It pulls together all my ‘pots’ and other assets – including my own home – via a bunch of dedicated sub-sheets.

Money market funds

If for some reason you don’t want to (or can’t) keep your portfolio’s long-term allocation to cash in a proper cash ISA, then money market funds may pay you a higher rate than your platform.

My co-blogger’s view is the teeny-tiny risk that comes with even the best of these funds – because they are funds, not cash – is not worth a slightly higher interest rate.

Read his comprehensive piece on money market funds to find out why.

I’m a little more sanguine. I wouldn’t keep all my cash in a money market fund (and my cash would only usually be a relatively small part of my portfolio, anyway) but I don’t think a toe in this pond will hurt in 99.99% of alternative histories. Legitimate money market funds almost never fail.

And even if something should go wrong, it’ll probably only cost you a delay in access or – worst case – a couple of percent in a very dire scenario. (I don’t think anything as bad as the latter has ever happened with a mainstream UK/US money market fund, for context.)

Still, there are risks. From market turbulence to incompetence to fraud and more.

Cash is cash and nothing else is cash.

Index-linked and conventional gilts

As I write you can earn more than 5% on a one-year gilt held to maturity.

That’s very hard to beat. There are tax advantages too if your cash is outside of a shelter.

Index-linked gilts pay a much higher real yield (because your 5% nominal on a vanilla gilt or cash in the bank is -4% in real terms with inflation at 9%). But they come with other complications.

Bonds have been terrible assets to own for the past couple of years. But over the long-term they’ve beaten cash on an annualized basis, and you’d expect them to do so in the future.

However even short-term conventional gilts are relatively volatile compared to cash.

Everything is volatile compared to cash!

So if you want your cash-like allocation to be unchanged day-to-day, then it has to be cash.

Other kinds of bond funds, and alternatives

Corporate bonds, high-yield bonds, REITs, absolute return hedge funds, infrastructure trusts…

…whatever bracket you want to include these in, they are not even close to cash.

Generally you should think of them as part of your equity allocation – not fixed income – when you think about your portfolio’s risk profile.

I won’t write more here because – yes – only cash is cash. These ‘cash proxies’ certainly aren’t.

How much interest on cash does your favourite broker pay?

To wrap up, you may have noticed that I have used the phrase ‘interest on cash in investment accounts’ several times in this article.

That’s because as mentioned we will eventually collate and update a table of rates for all the major brokers. And my SEO minions (um, that’s me and TA, armed with Google) have told us to put down a marker in advance, which we will revisit when we have all the data.

(This, incidentally, is also why you might feel like you’ve read the same story about your favourite 1990’s film star’s new spouse a dozen times. It’s a sorry side-effect of the modern Internet.)

Anyway, how about we crowdsource a few more brokers’ interest rates payable?

If you – whether as a user or an employee disguised as a user – can point me in the comments below to a URL that clearly lays out the interest on cash in investment accounts at a particular broker, then I will gratefully include it when we revise this post.

(Bonus marks if you can embarrass me by pointing to the rates at Lloyds…)

In the first instance we’ll add to the tables here. Later we can embed them on the broker comparison page.

Unfortunately the multitude of different tiers the brokers use mean it’ll probably be too much to ever expect a clear column making it easy to compare the different platforms’ rates.

Which, cynically, I expect is by design not accident.

Do you know the secret spot where your coy broker reveals what it pays in interest on cash in investment accounts? Let us know in the comments below.

What caught my eye this week.

A new study from The Centre for Policy Research reckons the UK citizenry has £1.8 trillion (yes, that’s with a ‘t’) tucked away in cash and National Savings and Investments accounts.

That’s comparable to the total market capitalization of the entire UK stock market.

With inflation near-9% and even the best cash accounts still paying only 5-6%, cash is hardly a bankable strategy to solve all our savings needs. Especially when most of it won’t be earning anything like Best Buy interest rates.

What’s more, the implication that the British public could swap all their cash savings to become the collective owners of Great Britain PLC – as listed, anyway – is beguiling.

As a card-carrying capitalist, that’s the kind of taking back control I could get behind.

Opportunity cost

To quote from the report’s executive summary:

Britain’s neglect of retail investing is surprising in both practical and ideological terms.

In practical terms, incentivising more retail investors, and encouraging more retail investment, should increase the amount of deployable capital available across the UK economy. It should help individual companies achieve their full potential, support economic growth at a national level and, in turn and in time, reward those who have made those investments.

In a 2017 paper for the Centre for Policy Studies (CPS) on the retail bond market, Rishi Sunak pointed out that 55% of the US population was then invested in the stock market, vs just 19% of Britons. ‘That division,’ he said, ‘represents a vast store of underworked capital.’

Little has changed since then; recent statistics from UK Finance suggest that 10.6% of UK household financial assets are currently held in equity, compared to 36.2% of US households.

Moreover, thanks to modern technology and the growth of investment apps the barriers to entry are historically low – certainly when compared to buying property. The ideological arguments are equally strong. Retail investing can be rewarding on an individual level, in terms of self-actualisation and self-worth. But it also gives people an opportunity to shape the companies they invest in – to literally become an owner, which includes the right to vote on corporate pay, environmental issues and governance. More retail investment gives people a stake in the society and the economy of which they are part.

All music to my ears. Obviously we’re champions for long-term investing in equities and other assets, and for people taking charge of their own finances.

The report’s recommendation to scrap the distinction between cash and shares ISAs seems especially overdue.

And encouraging a stronger connection between people’s thinking about capitalism and the bounty we enjoy would be an almighty win.

I’ve long-lamented how so many prosper under our market system and free trade while simultaneously moaning about and decrying it – blaming corporations for everything rotten on the left, or turning to nationalism and protectionism on the right.

A true shareholder democracy could be run more for the many than the few(er).

Reality returns

However even as the site’s resident (naughty) active investor, I do wonder about some of the report’s other proposed solutions to getting more people invested.

Deliberately trying to involve more everyday punters in IPOs, say. Or curbing the risk disclaimers around investment products.

These things are only a panacea in an ideal world, where people do even half as much research about investing as they put into planning their holidays – and where the typical financial advisor is more like a doctor than an estate agent, or worse.

Two decades of writing and talking about investing at Monevator leads me to suspect that a dash for retail’s cash would cause as many problems for everyday investors as it would solve.

If we could get several million more people investing more in low-cost index funds then sure, that’d be great.

If millions more people learned about and followed a sensible path to financial independence, the only downside from my perspective would that this website would be out of a job.

But you hardly need to be Martin Scorsese to picture what directing £1.8 trillion in cash towards far-riskier assets gate-kept by a freshly-deregulated financial services sector could look like.

Not so much The Wolf of Wall Street as The Silencing of the Lambs.

Tell Sid to leave the fantasy stockpicking-for-all stuff back in the 1980s.

Have a great weekend!
