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

The spread between bitcoin's dollar price on Coinbase and its USDT price on Binance has widened, driving the CryptoQuant Coinbase Premium Index to its weakest level in four weeks. Tuesday's reading was about -0.07%, a slim discount that translates to roughly $50 on a bitcoin priced near $75,900, and marks a deeper gap compared with the prior day's roughly -0.02%.

Market participants point to several factors behind the move. U.S. buying interest appears to have cooled following the failure of the Clarity Act to pass on Tuesday, reversing a trend from late August and early September when the Coinbase premium briefly turned positive as bitcoin approached $80,000. The retreat in bitcoin has left the premium in negative territory as domestic demand softens.

Macro developments are compounding the pressure. Traders widely expect the Federal Reserve to announce a 25-basis-point increase to lift the federal funds target range to 3.75%–4% later this week, tightening financial conditions. At the same time, benchmark U.S. 10-year Treasury yields have climbed above 5%, and oil prices remain elevated — Brent near $108 a barrel and WTI around $104 — amid Middle East tensions.

Analysts say the combination of regulatory uncertainty, higher yields and expensive energy creates a challenging backdrop for bitcoin and other risk assets. Higher borrowing costs can damp growth and raise financing costs for companies, while persistent energy-price pressure may sustain inflation, factors that can weigh on investor appetite for cryptocurrency exposure.
