SEC Implements Sweeping Reforms to Enhance Stability of the US Treasury Market

The Securities and Exchange Commission (SEC), in a decisive 4-1 vote, is set to introduce pivotal changes to the regulatory framework of the US Treasury market, which has a profound effect on the global financial landscape. These changes are geared towards reducing systemic risk in the $26-trillion market through the implementation of rules requiring more transactions, particularly involving cash treasury and repurchase agreements, to be settled via central clearing houses.

This decision marks the most substantial reform in the structure of the US Treasury market for decades and is part of a government-wide initiative aiming to address underlying structural issues that have been contributing to volatility and liquidity challenges.

Key to these reforms is the influence on hedge funds and proprietary trading firms that have come to represent a significant portion of the market. These entities, engaged in speculative 'basis trades' and often employing substantial levels of leverage, have been a particular focus for regulators. The overreliance on debt-fueled positions by these players posed a potential risk of market disruption if there were sudden and large-scale liquidations.

Moody’s Investors Service validated the regulatory proposition, suggesting that a centric clearing entity, which serves as a counterparty to all buyers and sellers, can function to suppress these risks by ensuring trade commitments despite defaults.

SEC chair Gary Gensler emphasized that the initiative aims to fortify the market's resilience under both stable and stressed conditions. These measures expand the obligations to clear trades, making it a requirement for clearing houses to clear cash Treasury transactions involving their members, primarily large broker-dealers, as well as dictate the clearing of repo and reverse repo transactions.

A central aspect of the reform is its impact on hedge fund activities in the repo markets. The practice entails exploiting discrepancies between future contracts and actual prices of Treasury bonds. The basis trade commonly used by macro hedge funds involves leveraging fundamental strategic discrepancies for profit.

Market analysis reveals the pervasive use of borrowed funds by hedge funds, frequently without adequate security, or 'haircuts,' indicating the potential risks from overleveraging in the market.

Highlighting the precariousness, Gensler outlined current practices' reliance on a “risky foundation of trades” and the significant leverage featured in relationships among banks, brokerages, and hedge funds.

In a measured response to industry concerns, officials from the SEC acknowledged a softening in their approach, particularly regarding treasuries bought and sold between broker-dealers and hedge funds or leveraged accounts. Central clearing will not be mandatory for these trades as the associated risks are broadly covered by repo trade clearing essentials, mitigating concerns that margin or collateral requirements could affect market liquidity.

The Fixed Income Clearing Corporation, the nation’s exclusive clearer of treasuries, and its members are provided with staggered timelines to align with the new regulations; March 2025 for risk management, asset protection, and access to services, and phases leading up to June 30, 2026, for repo transactions.

Market stakeholders have acknowledged these changes with cautious optimism, while recognizing the extensive work required to ensure effective and efficient implementation.
