Crypto rallied as Powell opened the door to a policy adjustment

Federal Reserve Chair Jerome Powell used his August 22, 2025 address at Jackson Hole to say that a changing balance between inflation and employment risks could justify an adjustment in monetary policy. Digital-asset markets rallied alongside other risk assets: CoinMarketCap’s August 22 historical snapshot placed bitcoin at $116,874.09, up 3.96% over its displayed trailing 24-hour window, while ether stood at $4,831.35, up 14.40%.

That pairing—not a crypto-specific policy decision—was the consequential development for the date. It showed how strongly a mature digital-asset market was trading on expectations about dollar liquidity and U.S. interest rates. The speech did not promise a September cut, and the price record alone cannot prove that Powell’s remarks caused every part of the move.

What Powell actually said

Powell described an economy with competing risks. The July employment report showed average payroll growth of 35,000 per month over the preceding three months, down from 168,000 per month during 2024. Unemployment was 4.2%, while the Fed’s estimates put 12-month total personal consumption expenditures inflation at 2.6% and core PCE inflation at 2.9% through July.

His policy message was conditional. The federal funds rate was still in restrictive territory, he said, but the baseline outlook and shifting risk balance “may warrant adjusting” the policy stance. He also said policy was not on a preset course and that the Federal Open Market Committee would base decisions on incoming data and the outlook.

That distinction matters. On August 22, markets received permission to price a greater possibility of easing; they did not receive a rate-cut decision. The next scheduled FOMC meeting remained a separate institutional event.

Crypto joined a broad risk rally

The crypto move was broad rather than confined to bitcoin. In the same CoinMarketCap snapshot, solana was $200.65 with an 11.30% trailing 24-hour gain, XRP was $3.0758 with a 7.90% gain, and dogecoin was $0.2406 with a 12.03% gain. Ether’s 14.40% increase exceeded bitcoin’s 3.96% move over that provider’s measurement window.

Traditional markets pointed in the same direction. Associated Press market coverage reported that the S&P 500 gained 1.5%, the Dow Jones Industrial Average rose 846 points, or 1.9%, and the Nasdaq Composite added 1.9% on August 22. That cross-asset response supports the interpretation that the crypto rally was part of a wider repricing of monetary-policy expectations rather than evidence of a new blockchain development.

The comparison has limits. Crypto trades continuously across venues, while U.S. equity indexes have a defined cash session. CoinMarketCap’s page is an aggregated historical snapshot with trailing 24-hour percentages; it is not a single-exchange closing auction, and the page does not expose an intraday sequence sufficient to isolate the speech’s effect. Prices and percentage changes may differ on another venue or under a different UTC cutoff.

Why the signal mattered

Interest-rate expectations affect the discount rates, funding conditions and risk appetite that reach both conventional and digital markets. The August 22 reaction therefore supplied a clear institutional lesson: crypto’s largest assets were behaving as macro-sensitive risk instruments even when the catalyst came from outside the industry.

The verified record supports a narrower conclusion than claims that Powell had guaranteed easier money or validated cryptocurrency. He had done neither. He identified rising downside employment risks, persistent upside inflation risks and room to consider a policy adjustment. Markets responded forcefully, with ether leading the major crypto assets in the cited snapshot, but the final policy decision and its consequences remained unknown on August 22, 2025.
