PANews reported on June 7th that, according to Coinglass data, the Coinbase Bitcoin Premium Index has been in negative territory for 20 consecutive days, with the latest value at -0.0467%. This index measures the deviation of Coinbase's (a major compliant US platform) BTC price from the global average. A sustained negative value indicates heavy selling pressure in the US market, declining risk appetite, capital outflows, or increased risk aversion. Historical data shows that prolonged negative premiums often accompany the departure of US institutional funds, suggesting potential short-term downward pressure.
