Original Title: Wall Street Pulls Back From Bitcoin』s Money-Spinning Basis Trade

Editor's Note: The once considered 'surefire' Bitcoin basis arbitrage is quietly losing its appeal: the open interest between CME and Binance is shifting, and the spread has narrowed to the point where it barely covers funding and execution costs.
On the surface, this is a squeeze in arbitrage opportunities; at a deeper level, the crypto derivatives market is maturing. Institutions no longer need to rely on 'arbitrage' for returns, and traders are shifting from leverage to options and hedging. The era of high returns through simple strategies is fading, and new competition will emerge in more complex and refined strategies.
Below is the original text:
The crypto derivatives market is undergoing a quiet yet significant change: one of the most stable and profitable trading strategies is showing signs of faltering.
The 'cash-and-carry' trade, commonly used by institutions—buying Bitcoin spot while selling futures to profit from the spread—is collapsing. This not only signals a rapid compression of arbitrage opportunities but also releases a deeper message: the structure of the crypto market is changing. The open interest of Bitcoin futures on the Chicago Mercantile Exchange (CME) has fallen below that of Binance for the first time since 2023, further indicating that the highly profitable arbitrage opportunities of the past are being rapidly eroded as spreads narrow and market access becomes more efficient.
After the launch of spot Bitcoin ETFs in early 2024, CME once became the preferred venue for Wall Street trading desks to execute such strategies. This operation is highly similar to the 'basis trade' in traditional markets: buying Bitcoin spot through ETFs while selling futures contracts to profit from the spread between the two.
In the months following the ETF approval, the annualized return of this so-called 'delta-neutral strategy' often reached double digits, attracting billions of dollars in capital—capital that was indifferent to the direction of Bitcoin's price movement, focusing solely on capturing the returns. However, it was precisely the ETF that drove the rapid expansion of this trade that also sowed the seeds of its demise: as more trading desks rushed in, the arbitrage spread was quickly erased. Today, the returns from this trade are barely enough to cover funding costs.
According to data compiled by Amberdata, the current annualized return for a one-month period is hovering around 5%, near its lowest level in recent years. Greg Magadini, Director of Derivatives at Amberdata, noted that around this time last year, the basis was close to 17%, but has now fallen to about 4.7%, barely enough to cover the threshold of funding and execution costs. Meanwhile, the one-year U.S. Treasury yield is around 3.5%, making the trade increasingly less attractive.
Against the backdrop of narrowing spreads, the open interest of CME Bitcoin futures has fallen from a peak of over $21 billion to below $10 billion, according to data compiled by Coinglass. In contrast, Binance's open interest has remained relatively stable, at around $11 billion. James Harris, CEO of digital asset management firm Tesseract, stated that this change reflects more of a pullback by hedge funds and large U.S. accounts, rather than a broad retreat from crypto assets after Bitcoin prices peaked in October.
Exchanges like Binance are the primary venues for perpetual contracts. These contracts are settled, priced, and margin-calculated continuously, often updated multiple times a day. Perpetual contracts, commonly referred to as 'perps,' account for the largest share of crypto trading volume. Last year, CME also launched smaller-sized, longer-term futures contracts covering crypto assets and equity indices, offering futures positions close to the spot market, allowing investors to hold contracts for up to five years without frequent rollovers.
Harris of Tesseract noted that historically, CME has been the preferred venue for institutional capital and 'cash-and-carry' trades. He added that CME's open interest being overtaken by Binance is 'a significant signal that the market participation structure is shifting.' He described the current situation as a 'tactical reset,' driven by lower returns and thinning liquidity, rather than a loss of market confidence.
According to a statement from CME Group, 2025 is a key inflection point for the market: as regulatory frameworks become clearer and investor expectations for the sector improve, institutional capital is expanding from single bets on Bitcoin to tokens like Ethereum, Ripple's XRP, and Solana.
CME Group stated: 'Our average daily nominal open interest for Ethereum futures in 2024 was about $1 billion, and by 2025, this number has grown to nearly $5 billion.'
Although the Federal Reserve's interest rate cuts have reduced funding costs, this has not driven a sustained rebound in the crypto market since the collective crash of various tokens on October 10. Current borrowing demand is weak, decentralized finance (DeFi) yields are low, and traders are more inclined to use options and hedging tools rather than directly leveraging directional bets.
Le Shi, Managing Director of market maker Auros in Hong Kong, stated that as the market matures, traditional participants now have more channels to express directional views, from ETFs to direct access to exchanges. This increase in choice has narrowed the price differences between trading venues, naturally compressing the arbitrage opportunities that once drove the growth of CME's open interest.
Le said: 'There is a self-balancing effect here.' He believes that as market participants continue to flock to the lowest-cost trading venues, the basis narrows, and the motivation to engage in cash-and-carry trades diminishes accordingly.
On Wednesday, Bitcoin fell by 2.4% at one point to $87,188 before paring losses. This decline briefly erased all gains for the year.
Bohumil Vosalik, Chief Investment Officer of 319 Capital, stated that the era of nearly risk-free high returns may be over, forcing traders to turn to more complex strategies in decentralized markets. For high-frequency and arbitrage-focused institutions, this means they need to look elsewhere for opportunities.
