Sequence of Returns Risk in Cryptocurrency Portfolios
Published 2026-02-05
Sequence of returns risk describes a simple but easily overlooked mathematical fact: when you are adding money to a portfolio, the order of good and bad years barely matters to your final result — but when you are withdrawing money from it, the order matters enormously.
Consider two retirees who both average the same return over a 20-year withdrawal period, but experience their returns in opposite order. Retiree A gets strong returns early and a crash late; Retiree B gets a crash early and strong returns late. Despite identical long-run averages, Retiree B typically ends up meaningfully worse off, because early withdrawals during a crash force the sale of more assets at depressed prices, permanently shrinking the base that could otherwise benefit from the later recovery.
This risk is magnified in crypto because the swings are larger. A traditional 60/40 stock/bond portfolio might see a bad year in the -10% to -20% range; Bitcoin has seen single-year and multi-year drawdowns well beyond -70% from peak. A crash of that magnitude early in a withdrawal period, combined with ongoing withdrawals, can push a portfolio to zero far faster than the same average return spread evenly across the years would suggest.
This is precisely what a Monte Carlo simulation is designed to reveal that a single average-return projection cannot: by randomizing the order of returns across 1,000 separate simulated paths, it surfaces the range of possible outcomes — including the unlucky sequences — rather than hiding them behind one optimistic average.
Frequently Asked Questions
Can sequence of returns risk be reduced?
Common approaches include holding a cash buffer to avoid selling depreciated assets during a downturn, reducing withdrawal amounts flexibly during bad years, or lowering the overall withdrawal rate relative to the portfolio's expected volatility.
Does sequence risk matter during the accumulation phase too?
Much less. While contributing money, a bad year early actually lets you buy more at lower prices, which can help long-run results. Sequence risk is primarily a decumulation (withdrawal) phase concern.
