GazzaBloom said:Interesting article here on cash buffers from Abraham Okusanya, creater of the Timeline.app planning software
Cash Buffers, Sustainable Withdrawal and Bear Markets - Timeline app
The article suggest that cash buffers reduce a portfolio's sustainability. His suggestion for the optimum is a "Good cash buffer" portfolio:- Good Buffer: this portfolio consists of a 60/30/10 in global equity, bond and cash. Withdrawals are only ever taken from cash, which is replenished if the cash allocation drops below 2%. The portfolio is rebalanced if the equity allocation is more than 10% up or down from the original allocation. This approach draws on earlier research (Okusanya, 2018 referenced above) which shows that implementing a cash buffer by reducing ONLY the bond allocation is a more effective strategy.
"Interesting that this was written before this years remarkable drop in bonds and stocks at the same time with bonds not acting as a hedge against the drop this time around."
Interesting in the sense that we've had far worse in the 1970s and Abraham would've included this in his analysis?2 -

What studies do you suggest to show that something other than my strategy with
37% growth equity
30% equity + bonds+infrastructure income funds
17% Wealth Preservation funds
16% Cash (mainly PBs)
would better meet my objectives?
"37% growth equity"
If you mean non "value" shares - this isn't something that has historically been optimal

"17% Wealth Preservation funds"
We don't have sufficient historical data so impossible to say (and some would exclude on that basis).
"infrastructure income funds"

It's about having a variable "cash buffer" as an investment strategy, where the idea is you draw from the cash buffer at times when equities are considered "low" and top up the cash buffer at times equities are considered "high".This is entirely equivalent to maintaining a constant asset allocation in your main portfolio but having a smaller side portfolio which you switch between equities and cash depending on the state of the market. Of course doing that makes it more obvious that you're trying to time the market...
Our cash is 10% of every bean we currently own, excluding house/car etc.
So is this a cash buffer, savings, emergency pot, or part of our portfolio?
Maybe I've just been using the wrong terminology, as to me it's just cash, available to us, alongside our other funds.Like you, I don't consider myself to have a "cash buffer" but I do have cash.Personally, I am spending cash at the moment rather than drawing from my pension or investments as, with the current inflation rates far exceeding interest rates on savings accounts, premium bonds etc then I want to reduce the level of cash that I hold. This isn't part of some fancy strategy but merely a gut response to the different economic weather that we are currently experiencing."When the people fear the government there is tyranny, when the government fears the people there is liberty." - Thomas Jefferson1 -

The analysis is for a 60/30/10 portfolio. I would like to see the same analysis for a 80/20 stocks/cash portfolio, see how that fares.0 -

4) "infrastructure income funds"
Ditto
2) "Growth equity" is intended to signify that long term above inflation growth is the objective. The allocations to countries, company size, sector and growth vs value is a second level decision. I am sympathetic to the arguments for value shares but over the past 10 years finding appropriate funds has not been too easy. Recent events have shown that I need to try harder.
3) My research shows that funds like CGT have met their stated objective of medium term wealth preservation possibly for decades and I am happy to trust fund managers whose objectives match mine and whose asset allocations look appropriate.
4) Infrastructure income funds are generally value oriented with guaranteed incomes rather different to bonds and general equity. So they provide some income diversification. My aim for Income is to get it from as many different sources as possible.4 -

Whereas someone needing to drawdown say 4% or more from their investments without a cash buffer, could be in trouble if there was a poor sequence of returns early on. I certainly wouldn't feel comfortable if I needed to drawdown 4% each year without having a cash buffer.

That's really my point. If you are withdrawing at above a sustainable withdrawal rate, there is no evidence that a cash buffer will increase your chances of success, in fact, it is likely to reduce the chances of success.

The concept of the SWR, if set correctly should negate the need for a cash buffer. Cash buffers are really a soother to calm the nerves during market downturns, but in the cold light of day they only serve to detract from portfolio performance and longevity.1 -

I shall crunch some numbers excluding our cash altogether and see where we're at, at month end.
How's it going, AKA, Nutwatch? - 12 month spends to date = 2.60% of current retirement "pot" (as at end May 2025)0 -

As regards the safety of an SWR would you really put a blindfold on when your 100% investment in VLS60 drops by 40% and say "what's the problem, I am within my SWR"?0 -
If cash is part of the 40 of a 60:40 portfolio, it will be subject to defined rebalancing rules. With a cash buffer there doesn't seem to be any defined rules as to when it should be drawn from and when it should be increased, other than when the market is "down" and when the market is "up".
