Bitcoin's Coinbase premium sinks to one-month low, here’s why

Bitcoin’s Coinbase COIN$172.07·Market Closed premium has fallen to its lowest level in four weeks, suggesting weakening U.S. demand as investors confront a setback for crypto legislation and the prospect of tighter monetary policy.

The premium measures the difference between bitcoin’s dollar price on Coinbase and its USDT price on Binance. CryptoQuant’s Coinbase Premium Index tracks that gap as a percentage of price. Tuesday’s reading of around -0.07% works out to roughly $50 on a $75,900 bitcoin - a thin margin but one that points to relatively weak buying demand on the U.S. exchange.

The discount has deepened to around -0.07% on Tuesday from roughly -0.02% a day earlier, as the Clarity Act failed to pass on Tuesday. That marks a reversal from late August and early September, when the premium turned positive for the first time in months, as bitcoin climbed towards $80,000. Bitcoin has since retreated to around $75,000.

Monetary policy presents another headwind. The Federal Reserve announces its decision later Wednesday, with markets widely expecting a 25-basis-point increase that would lift the federal funds target range to 3.75% to 4%.
