During his years leading Berkshire Hathaway, Warren Buffett became known for holding billions of dollars in cash reserves.

The famed investor has long favored a cautious stance, maintaining a cash cushion in case markets decline. At the same time, he has also suggested that he keeps substantial cash available so he can move quickly when the right opportunities appear.

Retirement savers do not manage sums anywhere near Buffett’s scale, but they can still apply lessons from his approach to strengthen their own plans. Relying only on cash can leave wealth exposed to inflation, while holding too little can force investors to sell during downturns, locking in losses and missing the benefit of a rebound. Buffett’s method blends aggressive investing with enough cash on hand to weather difficult periods.

Why cash is not always as safe as it looks

Cash can appear safe because its face value does not change, but that can be misleading. If you leave $100,000 in the bank and do not touch it for 10 years, the nominal amount will still be $100,000.

Even so, that $100,000 will not buy as much in 10 years as it does now. Prices of assets, goods, and services tend to rise over time. Food and housing are among the costs that have become more expensive over the past decade.

In addition to losing purchasing power, cash means missing out on potential investment growth. If that $100,000 earned an annualized 10% return, it could grow to $259,374 over 10 years. Many low-cost index funds can deliver returns in that range. Keeping money in cash means giving up those possible gains.

Why too little cash can create retirement risk

Holding too much cash carries risks, but the opposite extreme is not ideal either. If your entire net worth is invested in stocks, you may need to sell assets to cover everyday costs or unexpected bills such as medical expenses. That may not be a problem when markets are rising, but it can become painful during a sharp correction, when selling means realizing losses and reducing your ability to benefit from the next recovery.

There is also sequence-of-returns risk to think about when building a retirement portfolio. If withdrawals are required during a downturn in the early years of retirement, recovery becomes more difficult.

Ideally, the opening years of retirement go smoothly, but no one can predict how the market will behave. A common guideline is to keep enough cash to cover one to two years of living expenses before retiring. That reserve can help you stay invested through downturns and give your portfolio time to rebound.

What Buffett’s approach points to

Buffett’s habit of keeping sizable cash reserves served him well for years. It allowed his stock holdings time to grow without interruption while still leaving him ready to pursue new opportunities without draining all of his liquidity.

The strategy strikes a balance between stability and growth. His cash provides flexibility to handle expenses and remain committed to long-term positions. Retirees can take a similar approach by setting aside one to two years of living expenses in cash. That money can also be held in a high-yield savings account, certificates of deposit (CDs), or short-term bonds that pay interest.

Having that cushion can make it easier to keep part of a portfolio invested in stocks, which may deliver strong long-term returns and help support a retirement lifestyle for many years, or even decades.
