1–3 Year Cash Buffer: How Australians Can Manage Sequence of Returns Risk

Sequence of returns risk is the danger that poor investment returns in the early years of retirement, combined with regular withdrawals, permanently shrink a portfolio’s capacity to recover. It hits anyone drawing an income from savings, not just those with bad luck in the markets generally. The single most important step is to build a cash buffer and agree a flexible withdrawal plan with an adviser before you need either.

TL;DR:

Early negative returns paired with withdrawals can cause lasting damage, especially in the initial five to ten years after retirement.

Building a cash buffer to cover essential expenses and adopting flexible withdrawal rules significantly reduces sequence risk exposure.

A staged asset allocation approach, shifting toward more defensive assets before retirement and adjusting as needed, helps manage sequencing effects.

Mitigating strategies like partial annuitization and smoothed funds provide income stability but may limit growth or liquidity.

Proper planning, including modeling expenses and establishing withdrawal rules in advance, outperforms relying solely on static asset allocations or cash reserves.

What is sequence of returns risk and why does the order of returns matter?

During the years you’re building wealth, the order of your annual returns doesn’t matter much.

Drawdown changes the maths entirely. Once you start withdrawing, a downturn forces you to sell more units at depressed prices just to fund the same dollar amount of spending, leaving fewer units left to ride the eventual recovery. Schwab describes this as the core mechanism behind sequence-of-returns risk: early losses paired with withdrawals do more lasting damage than losses of the same size later on.

Accumulation phase: order of returns is largely irrelevant because there are no withdrawals to interact with.
Drawdown phase: order becomes critical because withdrawals lock in losses that a portfolio would otherwise have time to shake off.
The most dangerous window is what practitioners call the “retirement risk zone”, running from roughly five years before retirement to ten years after it.

A simple example: same average return, very different outcomes

Averages hide a lot. Two retirees can earn identical average returns over ten years and finish with vastly different balances, purely because of when the good and bad years landed.

Retiree A starts with $500,000 and withdraws $30,000 a year. The first two years deliver returns of negative 15% and negative 10%, before settling into steady 7% growth for the rest of the decade.
Retiree B starts with the same $500,000 and the same withdrawal, but the negative 15% and negative 10% years land in years nine and ten instead of years one and two, with 7% growth everywhere else.
Both retirees experience the exact same average annual return over the decade.
Retiree A finishes with a noticeably smaller balance than Retiree B, because early withdrawals during the loss years permanently reduced the capital base that later growth had to work with.

That gap is the whole risk in miniature. It’s why two people who retired eighteen months apart, with near-identical super balances, can end up on completely different financial footings a decade later.

How long does the danger last, and what raises your exposure?

The retirement risk zone spans several years before you stop work and the initial years following retirement, a period the Pension Bible guide to sequence risk identifies as carrying the highest concentration of risk. Balances are typically at their largest in this window, and withdrawals have just begun, so the dollar impact of a market fall is at its peak.

A few signals suggest your exposure is elevated right now: a large lump-sum withdrawal planned within the next two years, a market downturn arriving in the twelve months either side of your retirement date, or an essential income entirely dependent on portfolio performance with no other buffer. Any one of these on its own is manageable. Two or three together deserve a proper conversation with an adviser.

How do you manage sequence of returns risk in practice?

No single tactic removes sequence risk. Fidelity’s adviser research on sequencing risk makes the point that a combination of tools, matched to your own income needs, works far better than betting everything on one approach.

Cash buffer or bucket strategy. Hold a cash buffer covering essential spending in liquid, low-risk assets separate from growth assets. When markets fall, you draw the buffer instead of selling shares at a loss, then top it back up in stronger years. Investopedia’s guide to sequence risk treats this as one of the most practical protections available, and the sizing matters more than the concept: match it to essential spending, not your whole lifestyle budget.

Glide path or lifestyling. Gradually shift towards more defensive assets as retirement approaches, then consider increasing growth exposure again once you’re several years into drawdown and the risk zone has passed. GMO’s research on understanding and dealing with sequence risk argues that dynamic reallocation, responding to returns as they actually unfold rather than following a fixed pre-set path, can improve outcomes further.

Flexible withdrawals. Trim withdrawals after a down year and allow only modest increases after strong ones. Rules in this style, often associated with the Guyton-Klinger approach, have empirical support for extending how long a portfolio lasts compared with a fixed, unchanging withdrawal amount. It’s worth comparing this against a static benchmark like the 4% rule to see how much flexibility actually buys you.

Partial annuitisation or guaranteed income. Covering essential expenses with a guaranteed income stream, and leaving a smaller growth portfolio for discretionary spending, removes market risk from the money you can’t afford to lose.

Smoothed managed funds. These aim to dampen volatility without parking large sums in cash that earns little.

Five sequence risk mitigation strategies

Pro Tip: Size your cash buffer against your essential expenses only, not your total lifestyle spending. A buffer built for discretionary extras as well as necessities usually ends up too large, and excess cash is a quiet drag on your long-term retirement outcome.

What do you give up with each mitigation strategy?

Every one of these tools comes with a cost, and pretending otherwise sets people up for disappointment.

Cash buffers reduce long-term returns because cash rarely beats inflation by much over a decade. A heavier bond allocation smooths volatility but caps the growth that compounds your balance over twenty or thirty years. Flexible withdrawal rules mean your income can vary with the market, suiting those with adaptable budgets more than those with fixed essential expenses. Annuities remove sequence risk from the income they cover, but that money usually can’t be accessed as a lump sum later and won’t form part of your estate.

Your sequence risk checklist: what to do next

Model your essential and discretionary spending against your likely withdrawals, using a tool like the superannuation calculator or a proper adviser review, and check the result against current minimum pension drawdown rules.
Set a cash buffer covering one to three years of essential spending, separate from your invested portfolio.
Agree a glide path and a set of dynamic withdrawal rules with your adviser, written down, so you’re not making decisions under pressure during a downturn.
Consider partial guaranteed income for essential costs, and check how any change interacts with your Age Pension eligibility before you act.

Our retirement planning checklist walks through the broader preparation steps if you’re still a few years out.

How Amber Wealth approaches sequence risk for clients

Every plan starts with the same question GMO’s research frames well: what does your portfolio actually need to deliver, and when? That question shapes everything from asset allocation to how withdrawals get structured, rather than treating “growth” as the only objective.

In practice, a typical combined approach might pair a modest cash buffer with a staged glide path and a partial guaranteed income component covering essential costs, reviewed annually against actual drawdown needs. Our retirement planning and Age Pension strategy advice both feed into this kind of structure, because income needs and pension eligibility are rarely separate questions in practice.

Where the conventional advice on sequence risk falls short

Most of what gets written about sequence risk treats it as a portfolio problem to be solved with the right asset mix. That’s only half right. It’s genuinely a financing problem, as GMO’s research frames it: the question isn’t “what’s the optimal allocation” in isolation, it’s “what does this money need to fund, and when does it need to fund it?” Get that sequencing of needs clear first, and the allocation decision becomes far simpler.

The other gap in conventional advice is the obsession with cash as the default defence. A large cash allocation feels safe, but it’s a genuine drag on lifetime income if you overdo it. The research consistently points to smaller, targeted buffers, sized to essential spending, combined with flexible withdrawal rules and, where it suits your situation, a slice of guaranteed income. That combination beats any single tactic used alone.

If there’s one priority for someone reading this five years out from retirement, it’s this: don’t wait for a downturn to discover you don’t have a withdrawal plan. Build the rules now, while you can think clearly, not while you’re watching a balance fall.
