What Happens If Markets Fall in Your First 5 Years of Retirement?

The Most Dangerous Years

You've spent decades saving. You've built a portfolio. You've picked a retirement date. And then, in your first year of freedom, markets drop 20%.

This isn't a hypothetical. It happened to people who retired in 2000, 2008, and 2022. And the damage it does is far worse than the same drop happening ten years into retirement.

The reason is straightforward but widely misunderstood: when you're withdrawing from a falling portfolio, you're selling more units to generate the same income. Those units are gone. When markets eventually recover, you have fewer shares to benefit from the rebound.

This is sequence-of-returns risk — and the first five years of retirement are where it hits hardest.

A Tale of Two Retirements

Consider two people who both retire with £500,000 and withdraw £20,000 per year (a 4% withdrawal rate). Both experience an average annual return of 6% over 20 years. The only difference is when the bad years fall.

Retiree A hits a rough patch early — markets fall 15%, then 10%, then return 2% in years one to three. After that, strong returns follow for the remainder.

Retiree B gets decent returns in the first decade, then experiences the same downturn in years 11-13.

After 20 years:

• Retiree A has roughly £280,000 left
• Retiree B has roughly £510,000 left

Same average return. Same withdrawals. A difference of over £230,000 — driven entirely by the order in which returns arrived.

Retiree A was selling into a falling market when their portfolio was at its largest. The early losses carved away the base that everything else was supposed to compound from. Retiree B experienced the same losses, but by then they'd had a decade of growth and their portfolio could absorb the hit.

Why Recovery Doesn't Fix It

"But markets always recover" is the standard reassurance. And it's true — historically, major indices have always recovered from downturns given enough time. But recovery doesn't undo the damage if you were withdrawing throughout the fall.

Here's why. If your £500,000 portfolio drops 30% to £350,000, it needs a 43% gain just to get back to £500,000. That's the maths of percentage losses — they're asymmetric.

Now add withdrawals. If you're taking £20,000 per year during the downturn, your portfolio isn't just falling with the market — it's falling faster because you're pulling money out at the bottom. By the time markets recover, your pot might be at £300,000 instead of the £500,000 it started at. A full market recovery doesn't mean a full portfolio recovery.

This is the fundamental problem with treating retirement as a long-term investment. Over 30 years, the long run might look fine. But you're not investing a lump sum and leaving it. You're spending from it every month — and the early years have an outsized influence on whether it lasts. You can test how your plan holds up in a downturn — it takes a few minutes and it's free.

What History Tells Us

The UK market has experienced several significant downturns that would have severely tested early retirees:

• 2000–2003: The dot-com crash. The FTSE 100 fell roughly 50% from peak to trough. A retiree starting in 2000 would have been withdrawing through three consecutive years of losses.

• 2007–2009: The global financial crisis. UK equities fell around 45%. Anyone who retired in 2007 saw nearly half their portfolio value disappear within 18 months while still needing to fund living expenses.

• 2022: A combined equity and bond sell-off — unusual because bonds, traditionally a safe haven, fell alongside equities. A 60/40 portfolio offered little protection. UK gilt prices collapsed, and the FTSE 100 was relatively flat while global equities dropped.

In each case, the retirees who were hurt most were those in the first few years of drawdown. Those who had been retired for a decade or more had already built a buffer through earlier growth.

The Psychological Toll

The financial damage is measurable. The psychological damage is harder to quantify but equally real.

Watching your portfolio drop 25% when you're 35 and still earning feels uncomfortable but manageable. Watching it drop 25% when you're 66, no longer earning, and relying on it for income is terrifying. The natural response is to cut spending dramatically — cancelling holidays, reducing lifestyle, deferring home maintenance — even when the rational move might be to stay the course.

Some retirees panic and move to cash, locking in losses and missing the recovery. Others reduce withdrawals so aggressively that they live far below their means despite having enough. Both responses are understandable, but both lead to a worse retirement than was necessary.

This is another reason why planning matters. If you've modelled the bad scenarios in advance — if you've seen what a 30% early drawdown looks like in a simulation and know that your plan can survive it — you're far less likely to make emotional decisions when it actually happens.

What Can You Do About It?

You can't control markets. But you can control your exposure to sequence risk. Several strategies can reduce the damage:

Hold a cash buffer

Keeping one to three years of spending in cash or near-cash means you don't have to sell equities during a downturn. You live off the buffer while markets recover, then replenish it when conditions improve. This is conceptually simple and psychologically powerful — it turns a crisis into a waiting game.

Reduce withdrawals in down years

Rather than rigidly withdrawing the same inflation-adjusted amount every year (as the 4% rule suggests), consider flexible withdrawal strategies. If your portfolio drops 15%, reducing your withdrawal by 10% for a year or two can dramatically improve long-term sustainability.

This requires spending flexibility — which is easier if you've planned for it in advance and know which expenses are essential and which are discretionary.

Use the State Pension as a floor

The State Pension is a guaranteed, inflation-linked income that arrives regardless of market conditions. It acts as an income floor — the minimum you'll receive no matter what. If your essential spending is covered by the State Pension plus any defined benefit pensions, your portfolio only needs to fund discretionary spending, which is easier to reduce temporarily.

Manage your asset allocation

Your mix of equities, bonds, and cash matters more in the first five years than at any other point. Some retirees adopt a "rising equity glide path" — starting with a more conservative allocation at retirement and gradually increasing equity exposure over time. Research by Kitces and Pfau suggests this can reduce sequence risk because your highest equity exposure comes when your portfolio has had time to grow and can better absorb volatility.

Model the worst case

The most important thing you can do is understand your exposure before it materialises. Running your retirement plan through a Monte Carlo simulation that includes severe early downturns shows you what happens to your portfolio — and your income — under stress.

If a simulation shows you have a 95% chance of success but the bottom 5% of scenarios involve running out at age 82, that's information you can act on now. Adjust your withdrawal rate, build a bigger buffer, or delay retirement by a year. These are small changes made calmly, not desperate reactions made in a crisis.

The First Five Years Set the Tone

Retirement planning isn't just about how much you save. It's about how your portfolio behaves in the critical early years — and whether your plan can absorb a shock at the worst possible time.

The retirees who navigate this best aren't the ones who get lucky with timing. They're the ones who planned for bad timing and built a strategy that doesn't depend on markets cooperating from day one. You can stress-test your own plan for free and see how it holds up when markets don't cooperate.
