On Feb 26, Coinglass data shows Coinbase’s Bitcoin Premium Index flipped positive yesterday (Feb 25) at 0.0159%—ending a 40-day streak of discounts—before turning negative again today, though the gap has narrowed to -0.0033%. This signals warming buying sentiment in the U.S. market. BlockBeats Note: The Coinbase Bitcoin Premium Index measures the spread between Bitcoin’s price on Coinbase (a top U.S. exchange) and the global market average. It’s a key indicator for tracking U.S. capital inflows, institutional investment enthusiasm, and shifts in market sentiment. A positive premium means Coinbase’s price is above the global average, typically signaling: strong U.S. buying interest, active inflows from institutions or compliant funds, ample USD liquidity, and broadly optimistic sentiment. A negative premium (Coinbase price below the global average) usually reflects: notable U.S. selling pressure, reduced investor risk appetite, rising market risk aversion, or capital outflows.
