The basis arbitrage trading in U.S. Treasury bonds is surging, posing risks to financial markets.

Currently,Basic procedures for individual foreign exchange transactions the size of basis trade arbitrage in US Treasury securities has reached a record $1 trillion. Hedge funds are heavily betting on this trade, drawing significant market attention. This trade essentially involves shorting volatility, and if market fluctuations intensify, it could lead to massive liquidations, triggering cross-asset sell-offs and further exacerbating financial market volatility.

In recent years, many hedge funds have engaged in arbitrage between the small price differences in US Treasury spot and futures markets, but to enhance returns, they generally employ high leverage. This has inflated the scale of transactions to dangerous levels. If the market experiences intense volatility, these high-leverage positions may be forced to liquidate, affecting other financial sectors.

Experts point out that the scale of this arbitrage trade is now more than double the size that required Federal Reserve intervention in 2020, posing heightened systemic risk to the market. Hedge funds with high leverage are in highly aggressive positions in the current trading environment, and even slight changes in market spreads could force these funds out of the market.

Among the issues, resolving the debt ceiling could become a key factor in market volatility. If the debt ceiling issue is resolved, the US Treasury will reissue Treasuries that could not be issued due to the ceiling, leading to a sudden increase in Treasury supply. This could trigger three effects: rising interest rates, a liquidity drain effect, and a large-scale unwinding of basis trades. Experts believe that this supply shock could ignite significant market volatility.

In the face of this potential risk, some experts suggest that the Federal Reserve consider a "hedged bond buying" strategy instead of traditional quantitative easing (QE). This method could inject liquidity while avoiding market distortion risks associated with excessive Treasury purchases. Experts argue that this targeted policy tool will help address the risks faced by highly leveraged hedge funds and prevent large-scale asset sell-offs in the market.

Nevertheless, some opinions suggest that this strategy may encourage hedge funds to take on more risks, thus careful consideration is required before its implementation.
