According to Coinglass data, the Coinbase Bitcoin Premium Index has been in negative territory for 30 consecutive days, marking its longest losing streak so far in 2026, currently at -0.0566%. The Coinbase Bitcoin Premium Index measures the difference between the price of Bitcoin on Coinbase (a major US trading platform) and the global market average price. This index is an important indicator for observing fund flows, institutional investment activity, and market sentiment changes in the US market. A positive premium indicates that the Coinbase price is higher than the global average, typically signifying strong buying pressure in the US market, active participation from institutional or compliant funds, ample dollar liquidity, and optimistic investment sentiment. A negative premium indicates that the Coinbase price is lower than the global average, typically reflecting significant selling pressure in the US market, decreased investor risk appetite, increased market risk aversion, or capital outflows.
