The US repurchase market is facing a “big test” of the new 2027 liquidation regulations! Canadian Imperial Bank of Commerce warns that insufficient market preparation may cause interest rate fluctuations

The Zhitong Finance App learned that the Canadian Imperial Bank of Commerce (CIBC) strategists warned that as the deadline for mandatory central settlement of US treasury bond repurchase transactions is getting closer, market participants' preparations are still slow, which may cause financial institutions to concentrate on completing compliance adjustments by the end of June 2027, thereby disrupting market pricing and financing capacity, and driving a phased increase in repurchase interest rates.

According to a report issued by the International Swaps and Derivatives Association (ISDA), with only about eight months left until the mandatory liquidation deadline in June 2027, the central clearing transaction volume of US repurchase agreements has stagnated after growth slowed in the first few months of this year.

The Canadian Imperial Bank of Commerce's strategist team led by Michael Cloherty said in a report released on Friday that this development is deeply disappointing. The strategist pointed out that the main risk facing the market is not that large financial institutions will eventually be unable to meet regulatory requirements, but rather that a large number of institutions may concentrate on promoting compliance before the deadline, thereby impacting market pricing and transaction capacity.

According to the report, this centralized adjustment close to the deadline may push repurchase interest rates to rise before and after the official implementation of the new regulations. According to regulatory arrangements, the deadline for mandatory central clearing of US Treasury bond repurchase transactions is June 30, 2027. Regulators have previously reminded market participants that they should be fully prepared before the deadline.

The so-called central clearing means that both parties to the transaction complete transaction settlement and risk management through the central counterparty clearing agency, and no longer fully rely on bilateral transaction arrangements. This mechanism aims to reduce counterparty risk and improve market transparency and financial system stability.

However, the market's transition to a central clearing model still faces a number of unresolved operational and economic problems. Some of these arrangements may increase transaction costs and increase the amount of collateral that financial institutions need to provide.

Strategists believe that quite a few market participants will face higher costs after switching to central clearing, so they prefer to wait until the regulatory deadline is close to complete the full conversion of the clearing model.

This wait-and-see attitude may further exacerbate the risk of market concentration adjustments. Earlier this month, at a conference held at the International Securities Lending Association (ISLA), the asset management agency revealed that only about 25% of the documents required for central clearing have now been completed.

According to the conference situation quoted by Scott Skyrm, executive vice president of Curvature Securities, the relevant agencies expect to complete another 25% of the documentation work by June next year. This means that when the new regulations are officially implemented by some asset management agencies, only about half of their existing counterparties may complete the connections and preparations under the central clearing framework.

The Canadian Imperial Bank of Commerce believes that this lack of preparation may limit the ability of the market to trade and cause an imbalance between supply and demand for financing in the short term. Meanwhile, the US Securities and Exchange Commission (SEC) has yet to make a final decision on whether some transactions can be exempted from central clearing requirements, which also brings additional uncertainty to the market.

A key issue that the market is currently concerned about is whether regulators will grant broad exemptions to offshore transactions and transactions between related companies. If these transactions are exempted, it may help reduce the risk of market distortions during the implementation of the new regulations.

Conversely, if most related company transactions are also included in mandatory central clearing, the cost of large banks allocating liquidity and collateral between different legal entities may increase significantly.

The strategist pointed out that in this case, financial institutions may need to hold more liquidity separately in different entities within the group to meet central clearing and related risk management requirements.

This will reduce the flexibility of banks' balance sheets and may cause the market to experience more unstable pricing during periods of pressure. For financial institutions that are highly dependent on the repurchase market for short-term financing, this change is particularly noteworthy.

The repurchase market is an important short-term financing channel for the US financial system. Banks, traders, and other institutions obtain capital by using securities such as US Treasury bonds as collateral. Changes in repurchase interest rates not only affect the financing costs of relevant institutions, but may also spread to the wider financial market through the money market.

Although strategists do not expect central clearing reforms to cause sharp fluctuations in repurchase interest rates, Cloherty believes that the possibility of moderate price changes is high enough, and that major repurchase market lenders should consider hedging some financing interest rate risks.

Notably, the market adjustments brought about by the new regulations may not end immediately after the June 2027 deadline. The Canadian Imperial Bank of Commerce pointed out that financial institutions usually take a long time to adapt to changes in the market structure driven by regulations, so the adjustment pain of the US repurchase market may continue until 2028.

The strategist cites the “Basel III” liquidity regulation introduced after the 2008 global financial crisis as a reference. At the time, despite the long transition period set by relevant regulatory requirements, the market experienced obvious pricing distortions before banks completed business restructuring and optimized the efficiency of balance sheet use under the new rules.

According to the Canadian Imperial Bank of Commerce, financial institutions were eventually able to gradually adapt to the new regulatory framework, but this process took several years.

Overall, with the transformation of the US Treasury bond repurchase market to a mandatory central clearing system, the focus of the market's attention is shifting from the regulatory rules themselves to the actual preparation progress of financial institutions. If a large number of institutions continue to delay compliance adjustments, there may be a situation where centralized switching to a settlement model will occur before the end of June 2027, leading to short-term pressure on market financing capacity and increased fluctuations in repurchase interest rates.

However, the SEC's final decision on the scope of exemption from offshore and related company transactions, and whether financial institutions can complete the liquidation documents and counterparty connections in a timely manner will be important factors in determining the extent of the impact of this reform on the US financing market.
