This is a straightforward strategy intended to reduce the possibility of retirees – particularly those with many years of retirement ahead – having to sell investments at depressed prices to maintain their income in the event of an extended future downturn.

What is a volatility-and-downturn cash bucket?

Retirees and investors approaching retirement often set aside about two to three years of living expenses if possible in a volatility-and-downturn cash bucket. This provides a buffer against being forced to sell assets at the wrong time, which may cut the expected longevity of a portfolio and its ability to produce enough future growth.

In a recent commentary, actuaries Rice Warner emphasises how disciplined investor behaviour is critical to handling a sharp fall in share prices and how a cash bucket can assist them to remain disciplined.

There is typically a close link to market behaviour and investor behaviour. (Regular Smart Investing readers may have read our past discussions of these buckets.)

"The behaviour of stock markets is unpredictable as sentiment big part in short-term price movements," Rice Warner comments. "When people are upbeat about the economy, prices often rise exuberantly; when the market turns down significantly, it is usually fast and without notice.

"So, while we can say that investment markets," Rice Warner adds, "follow a cyclical pattern, no one can predict when the market will rise or fall. We also know that markets usually recover their losses over time, sometimes quite quickly."

And as the commentary says, the impact of a market downturn could be magnified for investors who "lock in losses by moving into more defensive strategies [such as switching to all-cash portfolios] at an inopportune time".

When and how can I create a cash bucket?

Investors often begin to build-up a cash bucket or buffer in their last few years before their planned retirement. For instance, some investors direct a proportion of their super contributions from their last few years in the workforce into a cash bucket within their super funds.

Other opportunities may arise to create a cash bucket including, say, an inheritance or the sale of an investment property. Some investors will simply increase the asset allocation to cash in their super funds – perhaps when periodically rebalancing their portfolios.

How big should I make my cash bucket?

While investors often set aside two to three years of living expenses in their volatility-and-downturn bucket, the size of the buffer and how it is built-up will depend on such personal circumstances as the size of an individual's retirement savings, age, investment timeframe and perhaps professional advice. When determining the size of your cash bucket, keep the age pension in mind if applicable.

How can I top-up my cash bucket?

Some investors direct a proportion of unspent income from their main diversified portfolio, such as a balanced or growth super fund, to top-up their cash bucket from time to time – particularly during stronger-performing years. And proceeds from regular rebalancing of an investor's main diversified portfolio can provide top-up money.
