The short version: XRP ($XRP) has dropped 7.1% in seven days, and the cause is a Federal Reserve rate hike bet. A rate hike is a decision by the U.S. central bank to raise the cost of borrowing across the economy, and traders on Polymarket now put 83% odds on that happening on September 16. The token traded at $1.35 on September 12, 2026, down 10.0% from its late-August peak above $1.50, with a market capitalization of $84.65 billion.
XRP is a high-beta asset. In plain terms, that means it swings wider than the broader market when macro traders pull back. Over the seven days to September 12, XRP's decline was 3.9 times Ethereum's drop of 1.8%. In a single day, XRP fell 2.4 times as far as Bitcoin's 1.3% loss. Bitcoin fell 5.2% over the week. BNB fell 1.3%. XRP fell 7.1%.
Over 30 days, the ranking flips. XRP is up 32.2%, ahead of Ethereum's 30.2%, Bitcoin's 20.9%, and BNB's 16.4%. The same characteristic produced both the worst seven-day number and the best 30-day number among the four tokens.
How oil became an XRP problem
The chain from crude oil to crypto prices runs through inflation and Fed policy. Brent crude reached $107 a barrel after U.S. strikes on Iran resumed on September 2 and Iran's oil exports fell to zero. Higher oil pushes up gasoline, freight, and food costs, which feed into the consumer price index. The September 11 CPI printed core inflation at 0.3% month over month against an expected 0.2%. That pushed Polymarket's September hike odds to 83%, up from 62% the day before, when the September 10 wholesale price index had already shown annual wholesale inflation at 5.4% year on year. The 10-year Treasury yield reached 4.95% on September 10, its highest in a year. When a government bond pays close to 5%, some money shifts away from assets that pay nothing. XRP pays no yield. The federal funds upper bound already sits at 3.75%.
Positioning data ahead of the Fed decision
XRP's funding rate reached -0.0094% as of September 12, the most negative reading since June 28, 2026, per CoinGlass. A funding rate is a small periodic payment that keeps perpetual futures contracts aligned with the spot price. A negative reading means short sellers are paying long holders to keep their positions open.
ETF inflows into XRP went to zero on September 11, after $12.29 million on Tuesday and $5.14 million on Wednesday. U.S. spot Bitcoin ETFs ran four straight outflow days through September 11. The institutional money that carried both coins through August is sitting out the Fed.
XRP's Bollinger Bands, which measure how tightly price swings around its 20-day average, compressed into a narrow horizontal line as of September 12. The last time that happened, XRP drifted sideways for 236 days before its August 31 breakout. Ripple added AI agents to its treasury platform on September 10, and co-founder David Schwartz made bullish comments on September 9. Neither development moved the price. The Fed announces its decision at 2 p.m. Eastern on September 16.
