Coinbase Bitcoin premium negative for record 47 straight days

The Coinbase Bitcoin Premium Index has been negative for 47 consecutive days since May 19, setting a new all-time record for its longest negative streak, according to data from Coinglass. The index, which measures the price difference between BTC on Coinbase and the global average, is a key indicator of U.S. institutional investor fund flows and sentiment. A sustained negative reading suggests that selling pressure is relatively strong in the U.S. market, reflecting a weakening appetite for risk assets, capital outflows, or dampened investor sentiment. Historically, prolonged periods of a negative Coinbase premium have often coincided with U.S. institutional funds exiting the market, leading to analysis that suggests caution is warranted regarding potential short-term price corrections.
