Coinbase Negative Premium Widens, U.S. Buying Power Remains Muted
Data from Coinglass shows that the Coinbase Bitcoin negative premium index has reversed its mild improvement seen between February and May, weakening again since May 8. The index has recently expanded at a faster pace, hitting -0.1323% at last check, signaling that U.S. market buying power has once again fallen into a sustained slump.
The Coinbase premium index measures the difference between Bitcoin’s price on Coinbase and the global average price. As the largest regulated crypto exchange in the United States, Coinbase’s premium is widely seen as a barometer of domestic market sentiment. A negative premium typically indicates greater selling pressure in the U.S., reflecting lower investor risk appetite, rising risk-aversion, or capital outflows. After experiencing a period of moderate improvement from February through May that briefly hinted at local recovery, the index has deteriorated sharply. Since May 8, it has stayed in negative territory for several consecutive days with the discount widening, underscoring persistently fragile confidence among U.S. investors.
The renewed weakening of the index further confirms sluggish demand for crypto assets in the U.S. and highlights thin buying support, with market sentiment tilting toward conservatism. While other global markets have remained relatively steady, the continued expansion of Coinbase’s negative premium suggests that capital is still rotating out of risk assets, and U.S.-based selling pressure could continue to weigh on the market in the near term.
