Bitcoin futures carry trades on CME are now offering higher annualized yields than U.S. Treasuries, prompting over $850 million in net inflows to spot Bitcoin ETFs as institutional investors seek new sources of return amid shifting market conditions
Bitcoin futures on the CME are quietly outpacing U.S. Treasuries in annualized yield, drawing renewed attention from institutional investors and driving a surge in spot Bitcoin ETF inflows. According to CryptoSlate, gross annualized yields for Bitcoin futures carry trades reached as high as 7.89% on August 7, well above the 4.19% yield on two-year Treasuries for the same date. This shift is prompting some Wall Street desks to revisit the cash-and-carry trade, where investors buy spot Bitcoin and simultaneously short futures to capture the premium as prices converge.
Futures Carry Outpaces Bonds
Recent data from CME settlement bulletins and the New York Bitcoin benchmark show that the August CME Bitcoin futures contract settled at $65,175, translating to a 7.89% gross annualized basis. September and December contracts offered 6.25% and 5.69% respectively, all exceeding the Treasury benchmark. While analyst Marc Baumann previously noted that Bitcoin's futures basis had lagged Treasuries for over five months, the August 7 figures mark a clear break in that trend. The calculation depends on contract selection, roll conventions, and funding costs, which can vary across trading desks.
Mechanics and Risks of Carry Trades
The Bitcoin cash-and-carry strategy involves buying spot Bitcoin and selling futures, aiming to lock in the difference as the futures premium decays toward expiry. While the gross basis appears attractive, actual returns depend on financing the spot leg, margin requirements, trading fees, and execution costs. The Bank for International Settlements has documented that, at times, one-month CME Bitcoin carry trades exceeded 20% annualized in 2021, but also highlighted risks such as leverage, margin calls, and liquidation that can disrupt positions before convergence. For institutional desks, the net spread after all costs determines whether capital stays in the trade or moves elsewhere.
ETF Flows and Market Structure
U.S. spot Bitcoin ETFs recorded $853.54 million in net inflows for the week ending August 7, with positive flows each day. While these inflows indicate strong demand, public data does not reveal how much of this activity is paired with short futures as part of carry trades. Aggregate position data from the Commodity Futures Trading Commission shows overall market exposure by participant type but does not link ETF purchases to specific futures hedges. According to CryptoSlate, the recurring carry mechanism is visible in market structure, but trader-level data connecting ETF inflows to futures shorts remains unavailable.
For context, the July comparison between daily and monthly ETF flows showed that U.S. spot Bitcoin ETFs took in about $172 million net during July, with some days contributing over $200 million. This highlights the variability in inflows and the challenge of matching ETF activity to futures positioning. The lack of granular data means that while the carry trade is likely a driver, other institutional motives may also be at play.
Bitcoin's price can rise on directional buying even when the carry spread is unattractive, and the most useful institutional gauge is the net basis after funding costs, considered alongside ETF flows and CME positioning.

Market Data and Historical Context
On August 7, the CME August Bitcoin futures contract settled at $65,175, with the September and December contracts at $65,425 and $66,285, respectively. The two-year U.S. Treasury yield was 4.19% on the same date, according to the U.S. Treasury Department. The gross annualized basis for these contracts ranged from 5.69% to 7.89%. U.S. spot Bitcoin ETFs saw $853.54 million in net inflows for the week ending August 7, based on CryptoSlate data. These figures reflect a notable shift in relative yield and institutional positioning compared to earlier in 2026, when Treasuries consistently outperformed Bitcoin carry trades.
Bitcoin futures carry trades are a recurring feature of crypto market structure, but their profitability depends on a complex mix of funding rates, margin requirements, and execution costs. While the current environment favors the strategy over Treasuries, the trade is not risk-free. Market participants must account for the potential impact of volatility, liquidity constraints, and regulatory changes. As institutional capital continues to flow into spot Bitcoin ETFs, the interplay between futures and spot markets will remain a key area to watch for both yield-seeking investors and those tracking broader market dynamics.
