Treasury Market Trades Continue to Attract Scrutiny for a Variety of Reasons

Within the expansive $26 trillion Treasury market, renowned for its depth and liquidity in government debt, a specific trading strategy continues to attract attention as the year-end approaches – the "basis trade." This tactic involves capitalizing on the price differentials between Treasurys and Treasury futures, where seemingly minute differences can lead to substantial profits or losses, especially when leverage comes into play.

‍

In essence, the basis trade adopts an arbitrage approach by leveraging funds borrowed from the repo market for financing. The strategy entails assuming a short position in Treasury futures and a long position in actual Treasury securities, aiming to profit from the price gaps between the two. Typically, futures contracts trade at a premium to cash Treasurys, creating an opportunity for traders.

‍

Recognizing the potential risks associated with such trades, the Securities and Exchange Commission (SEC), under the leadership of Gary Gensler, has taken steps to enhance oversight. In a recent move, the SEC mandated that transactions involving repurchase agreements utilize a clearinghouse, positioned between buyers and sellers, with the objective of mitigating systemic risk.

‍

This heightened scrutiny follows concerns raised by the Federal Reserve in August, which emphasized the need for vigilant monitoring of leveraged Treasury trades by hedge funds. The Fed staff's report suggested that the unwinding of such trades may have contributed to market instability in March 2020. Strategist Steven Zeng of Deutsche Bank echoed these concerns, particularly regarding the potential consequences of a rapid unwinding of basis trades.

‍

Despite the current environment of elevated U.S. interest rates, the use of the basis trade persists. Market observers suggest that any rapid unwinding of these positions is more likely to occur due to forced selling by a specific firm rather than as a response to prevailing interest rate conditions.

‍

Ben Emons, senior portfolio manager and head of fixed income at NewEdge Wealth in New York, acknowledges the SEC and Fed's scrutiny, noting the highly leveraged nature of these trades. While recognizing the potential idiosyncratic nature of a rapid unwinding, Emons speculates that the SEC's new central-clearing requirement could also influence the dynamics of the basis trade.

‍

However, not everyone views the basis trade negatively. The Committee on Capital Markets Regulation, backed by the financial industry, contends that concerns surrounding the basis trade are overstated. They argue that current trading activity is below the peaks observed in 2019-2020 relative to total Treasury debt outstanding.

‍

In November, Ken Griffin, head of the investment fund Citadel, suggested regulators focus on banks rather than hedge funds to safeguard the financial system against risks arising from arbitrage trading of U.S. government bonds. Rostin Behnam, chairman of the Commodity Futures Trading Commission, downplayed media attention on the basis trade, asserting that the sizes of the futures and cash markets for Treasurys align with historical patterns.

‍

Recent reporting by Bloomberg identified several firms with traders considered key players in the basis trade, including Citadel, Tudor Investment Corp., Balyasny Asset Management, and Kedalion Capital Management. However, these firms declined to comment when approached by MarketWatch. Other firms mentioned in the Bloomberg report did not respond to requests for comment, including ExodusPoint Capital Management, Millennium Management, Capula Investment Management, and Symmetry Investments.

As the Treasury market experienced little change in yields during Friday's pre-holiday shortened session, the scrutiny and debates surrounding the basis trade persist, underscoring the ongoing importance of monitoring and regulating these complex financial maneuvers.
