Svmuureported that the Coinbase Bitcoin Premium Index has been in a negative premium range for 20 consecutive days, with the latest reading at -0.0467%. This index measures the deviation of Coinbase (a major US-compliant platform) BTC price relative to the global average price. A sustained negative value indicates heavier sell-side pressure in the US market, declining risk appetite, capital outflows, or heightened risk aversion. Historical data shows that prolonged negative premiums often accompany the withdrawal of US institutional capital, warranting caution against short-term correction pressures.
