Weekend reading: Bengen bails on the 4% rule

What caught my eye this week.

I am a couple of weeks late to this. But I can’t be the only investing nerd who hadn’t heard – and was surprised to learn – that Bill Bengen has broken his own 4% rule.

For those new to these parts, a short summary.

In the early 1990s Bengen interrogated the historical return data for US shares and bonds. He determined that a 4% withdrawal rate from a retirement pot – increased with inflation after the first year – would nearly always see you through a 30-year retirement without you running out of money.

For more detail read our articles on sustainable withdrawal rates [1].

I’m not delving into the specifics today. What’s fascinating to me is the man made famous for partially solving the retirement problem / neatly branding a nifty bit of data-mining (pick your poison) has bailed on it in his 70th year.

Alas the primary source for the Bengen revelation lies behind a Wall Street Journal [2] paywall (though a reader letter [2] in response is viewable). I picked up the news on a recent Animal Spirits [3] podcast.

In the podcast retirement demigod Wade Pfau says he hopes the news that Bengen was now 70% in cash will make people realize there’s no one-size-fits-all approach to income after work.

Indeed Pfau estimates that only about a third of the population have the right mindset for an equity-heavy total return drawdown strategy in retirement.

If that’s right then it means most people should be doing something different!

There’s not one rule to rule them all

Too often discussions of alternative approaches to retirement income (such as our old contributor The Greybeard’s equity income [4] trust preference) get talked down as irrational or atavistic.

But in my view the only investing that ever works long-term is the style that works for you.

And as I’ve said many times before, in retirement a different set of problems may mean you’re best off turning to a different solution.

Of course if people making unfounded claims – that dividend income gives you a free lunch, or that an annuity is the only sensible way to invest your retirement pot, or that buy-to-let properties guarantee superior results, or that you need active managers to get you through a bear market (Merryn Somerset-Webb’s latest [5] in the FT ) – then such specifics can be challenged.

My point is simply that there are trade-offs and advantages to all the approaches.

And that includes the ‘4% of a total return’ route – which might still, equally, be exactly right for you.

For once though you don’t have to take my word for it. Just look at the lived reality of Bill Bengen.

The man who wrote the rule on retirement investing is breaking that rule in spectacular fashion, because it turned out not to work for him. I commend him for sharing this so (sort-of) publicly.

Have a great weekend!
