Bitcoin futures carry has fallen to about 3%, below average 2-year Treasury yields, undermining the basis trade even as tighter spreads and lower volumes point to a more efficient market.
Glassnode said Bitcoin's 3-month futures basis has remained below the yield on the 2-year U.S. Treasury since February, with its Sunday chart showing the basis underperforming the note for 157 straight days. The relationship is closely watched as a gauge of the cash-and-carry trade, in which investors buy spot Bitcoin or a spot exchange-traded fund and sell futures to capture the basis. That trade, which yielded 20% or more during the 2021 bull market and at times ran above 30%, now returns about 3%, versus an average 3.8% yield on two-year Treasuries. The compression has reduced the incentive to deploy capital into bitcoin futures arbitrage and has coincided with a sharp drop in trading activity. Coinglass data cited in the report showed bitcoin futures trading volume peaking at $1.47 trillion in February 2026 before falling to about $880 million in July 2026. Analysts say the shrinking basis reflects weaker sentiment in a broader crypto bear market, but it also points to tighter spreads, better liquidity, easier hedging and fewer arbitrage opportunities as the futures market becomes more efficient.
