Wall Street liquidity radar: U.S. bitcoin discount deepens as prime volume jumps 122%

U.S. spot bitcoin traded at a deeper discount to offshore markets, even as institutional trading through Coinbase Prime rose sharply. Price sentiment and actual execution remained split, leaving the market short of a clear directional signal. Coinbase premium moved from -0.1099% on Oct. 9 to -0.0935% on Oct. 10, then to -0.1132% on Oct. 11, -0.1313% on Oct. 12 and -0.2236% on Oct. 13. A positive Coinbase premium indicates U.S. investors are paying more than offshore buyers, while a negative reading means U.S. spot prices are cheaper.
