Warren Buffett rarely talks about Social Security itself, but he has spent years warning about something that affects every person who depends on it: inflation. He often calls rising prices a "silent tax" because it eats away at what you can buy, even when your income doesn't change.

In the next sections, we explain Buffett's main inflation warnings and how they affect your benefit and your plans to retire comfortably.

How rising prices shrink the value of your check

Warren Buffett has warned for decades that inflation can shrink your wealth even when you're not spending more.

He once explained that the mix of inflation and taxes creates what he called an "investor's misery index." If that index rises faster than your returns, your real wealth can shrink. Your balance may look the same, but it buys less.

Buffett has also cautioned that "substantial inflation lies ahead," even while admitting that no one can predict the exact rate.

If you rely on Social Security, this warning matters even more. Your benefits rise with a yearly cost-of-living adjustment, but COLAs don't work in real time. They use last year's CPI-W (Consumer Price Index for Urban Wage Earners and Clerical Workers) data, which means they often lag behind actual price spikes.

You can see that in recent increases: 3.2% in 2024, 2.5% in 2025, and 2.8% in 2026. These boosts help, but many core expenses, especially health care and housing, have risen faster. In mid-2024, for instance, health care inflation even outpaced the broader CPI.

To protect yourself, you may want to take steps that give your income more room to handle rising prices:

Delay claiming if you can, since waiting can boost your monthly check
Work a little longer to add higher-earning years to your record
Pick up small amounts of part-time income to cover rising costs

These steps won't eliminate inflation, but they can help your Social Security check stretch further as prices climb.

Why fixed income leaves retirees vulnerable

Buffett has warned that relying too much on fixed income or cash can backfire when prices rise.

He once said, "Today, people who hold cash equivalents feel comfortable. They shouldn't. They have opted for a terrible long-term asset, one that pays virtually nothing and is certain to depreciate in value."

Basically, if your income stays the same while everything around you gets more expensive, you slowly lose buying power.

You can see this play out with Social Security, where your monthly check works a lot like a long-term bond.

It gives you a steady amount each month, and aside from the annual COLA, you don't have a way to raise it when your expenses grow. That means inflation plays a big role in how far your benefit actually goes.

If prices rise faster than your COLA, you feel the gap almost immediately. For example, if prices rise 4% but your benefit increases 3%, your buying power slips a little. The number on your check is bigger, but it doesn't stretch as far. That difference shows how fixed payments can lose value when costs keep climbing.

Why you need more than government benefits to stay secure

No matter how steady Social Security feels, depending on one fixed government benefit can leave you exposed when prices rise.

Even though Social Security benefits include annual COLAs, the adjustment only happens once a year. If inflation jumps in the middle of that cycle, your monthly check loses purchasing power right away, and you feel the difference long before the next increase arrives.

That's why treating Social Security as your only income source can be risky.

Having more than one income source, such as a pension, part-time work, annuities with inflation features, or withdrawals from savings, can help spread that risk. If one source comes under pressure, you have others to help steady your budget.

You also need to think about how long retirement might last and how taxes may affect what you keep. A longer life means more years of rising costs, and Social Security can be taxed if you have other income.

Building savings or creating extra income sources can help you stay ahead of those pressures instead of reacting to them later.

Bottom line

Buffett's long-running message on inflation comes down to staying aware and staying flexible. Prices rise over time, and Social Security, as useful as it is, covers only part of what you need.

You can strengthen your position by saving regularly, investing with care, and choosing the right time to claim your Social Security benefits.

When you build extra income sources and keep an eye on inflation, you protect more of your buying power and keep your retirement plan steady, even in the kind of price environment Buffett has warned about for years.
