The Retirement Number Nobody Talks About: Sequence of Returns Risk

Most retirement conversations focus on one number: the corpus. But reaching a target corpus is only one part of the problem. Once regular employment income stops and you begin withdrawing money, the order in which investment returns occur can matter much more than many investors realise.

What is sequence of returns risk?

Sequence of returns risk refers to the possibility that the order of investment returns can materially affect the outcome of a portfolio when withdrawals are being made. Two portfolios can experience the same average returns over a period but produce different outcomes if the sequence of those returns is different.

Why does withdrawal change the equation?

Before retirement, a market decline can potentially be followed by future contributions and a longer recovery period. During retirement, the investor may be withdrawing money while the portfolio is also declining. That combination can put greater pressure on the remaining capital.

A simple illustration

Imagine two retirees with similar portfolios and similar long-term average returns. One experiences strong returns in the first few years of retirement and weaker returns later. The other experiences a sharp decline early in retirement followed by stronger returns. Their final outcomes can be very different even if the average return over the full period looks similar.

The early-years problem

The first few years after retirement can be especially important because withdrawals are beginning at the same time that the investor may have less ability to replace capital through employment income.

Why a market fall can hurt more during withdrawals

Suppose a portfolio falls 20% while the investor needs to withdraw money for living expenses. Some units or assets may need to be sold at lower prices. The remaining portfolio then has fewer assets available to participate in a future recovery.

This does not mean market falls are always disastrous

The outcome depends on the portfolio, withdrawal rate, asset allocation, liquidity, other income sources and how long the retirement lasts. The point is that withdrawals change the mathematics of market volatility.

The retirement corpus is not the whole plan

A retirement plan should consider expenses, inflation, longevity, other income, healthcare, debt, taxes, asset allocation, liquidity and withdrawal strategy. A corpus number without these assumptions can create false confidence.

Inflation makes the problem harder

Retirement expenses can rise over time. A withdrawal amount that feels comfortable today may need to increase later if the cost of living rises.

Longevity matters

A retirement portfolio may need to support a person for several decades. The longer the retirement period, the more important it becomes to consider the interaction between withdrawals, investment returns and inflation.

Other income can reduce pressure

Pension income, rental income, part-time work or other reliable cash flows can reduce the amount that needs to be withdrawn from the investment portfolio.

Liquidity can create flexibility

Having a portion of the portfolio or household finances positioned for near-term spending can reduce the need to sell volatile assets immediately after a market decline. The exact structure depends on the individual's circumstances.

Asset allocation still matters

Retirement does not automatically mean moving everything into low-risk assets. Nor does it mean maintaining an aggressive allocation indefinitely. The appropriate mix depends on spending needs, risk capacity, time horizon and other resources.

The danger of a one-dimensional retirement rule

Rules such as 'I need ₹X crore' or 'I can withdraw Y%' can be useful starting points, but they are not complete retirement plans. Their suitability depends on assumptions about returns, inflation, spending and longevity.

What about the withdrawal rate?

A sustainable withdrawal approach should consider the portfolio's risk, expected spending needs, flexibility in expenses, other income and the length of retirement. A fixed percentage is not automatically suitable for every household.

Flexible spending can matter

Some retirees may be able to reduce discretionary spending during difficult market periods. That flexibility can potentially reduce the amount withdrawn while the portfolio is under pressure.

Essential and discretionary expenses are different

Housing, food, utilities, healthcare and necessary family support may be difficult to reduce. Travel, large purchases and some lifestyle expenses may be more flexible. Separating these categories can make retirement planning more realistic.

A cash-flow plan can be more useful than a corpus headline

Instead of asking only 'How much do I need?', ask 'How much will I need each year, which income sources will cover it, and which assets will fund the gap?'

What if retirement is still far away?

Sequence risk is most directly associated with the period when withdrawals begin, but the lesson can influence planning earlier. Building an appropriate asset allocation and periodically reviewing the path toward retirement can improve preparedness.

The retirement glide-path idea

As a goal approaches, investors may review whether the portfolio should gradually change its risk profile. This does not imply a universal formula. It means recognising that the ability to recover from a large loss may change as the goal gets closer.

What if markets fall just before retirement?

A large decline close to retirement can change the amount of capital available and may require a review of the retirement date, spending assumptions, asset allocation or other sources of income. It is a planning problem, not necessarily a reason to panic.

What if markets fall just after retirement?

This is where sequence risk becomes particularly relevant. The response should focus on liquidity, spending flexibility, other income and whether the portfolio was designed to withstand such a period.

Don't confuse this with predicting the market

Nobody can reliably know which years will produce strong or weak returns. Retirement planning should therefore focus on resilience rather than trying to forecast the perfect market cycle.

What this does NOT mean

Sequence of returns risk does not mean retirees should avoid equity completely, that markets will definitely fall after retirement, that one withdrawal rule works for everyone or that a particular asset allocation guarantees safety.

A better retirement framework

RETIREMENT GOAL → EXPENSES → INFLATION → OTHER INCOME → LIQUIDITY → ASSET ALLOCATION → WITHDRAWAL APPROACH → STRESS TEST → REVIEW.

The retirement stress test

Ask: What happens if markets fall significantly in the first few years? What if inflation is higher than expected? What if retirement lasts longer? What if healthcare costs rise? What if one expected income source disappears? A plan becomes more useful when it is tested against uncomfortable scenarios.

The 'first five years' conversation

Instead of focusing only on the retirement date, pay special attention to the early years after retirement. How much cash flow is required? Which assets will fund it? How flexible are expenses? What happens if markets

are weak?

North Horizon perspective

Retirement planning is not simply about reaching a large number and hoping the portfolio behaves. It is about creating a structure that can provide income across uncertain markets and an uncertain lifespan.

A simple framework to remember

RETIREMENT ≠ CORPUS ONLY. CORPUS + CASH FLOW + TIME + INFLATION + WITHDRAWALS + RESILIENCE.

The North Horizon takeaway

The number you retire with matters. But so does what happens after you retire. Sequence of returns risk is a reminder that accumulation and withdrawal are two different phases — and your financial plan should recognise the difference.
