U.S. debt-limit deadlock is making this favorite asset more scarce

The U.S. debt-ceiling impasse since January has led to a shrinking supply of Treasury bills, a favored asset for the $7.4 trillion money-market-fund industry, the second-largest investor in the $6 trillion T-bill sector. As the supply of T-bills dwindles (estimated to have shrunk by $375 billion through May), competition increases, potentially leading to shrinking yields, with the 3-month Treasury bill already down to 4.35%. While the Senate considers a bill to raise the debt limit, Barclays analysts anticipate a potential $1.4 trillion to $2 trillion deluge of new bill issuance through 2026 upon resolution, which would be a positive for the money-market-fund industry.

Analysis

The ongoing U.S. debt-ceiling deadlock, in effect since January, has significantly constrained the supply of Treasury bills (T-bills), a crucial asset class for the burgeoning $7.4 trillion money-market-fund industry, which ranks as the second-largest investor group in the $6 trillion T-bill market. This scarcity, with an estimated $375 billion reduction in outstanding T-bills through May according to Barclays, is fostering increased competition for the available assets, thereby exerting downward pressure on yields. For instance, the 3-month Treasury bill yield has declined to 4.35%, down from approximately 5.4% a year prior, a move also influenced by Federal Reserve rate cuts last year. While the House has passed a bill to raise the debt limit by $4 trillion, its progression through the Senate remains pending, and negotiations are ongoing. The Treasury is consequently approaching its "X date," estimated around mid-August, when it may exhaust emergency cash-management measures. In response to the dwindling T-bill supply, some money-market funds are diversifying into longer-duration Treasury securities and repurchase agreements. Despite U.S. stock indexes nearing record highs, investor appetite for cash-like havens remains strong, with money-market fund assets reaching a record $7.4 trillion in early June. A resolution to the debt-ceiling impasse is anticipated by Barclays to unleash a substantial $1.4 trillion to $2 trillion in new T-bill issuance through 2026, a development viewed positively by industry participants like Federated Hermes, as it would alleviate current supply-induced yield distortions and benefit money-market funds.

Key Decisions for Investors

• Investors should closely monitor U.S. debt-ceiling negotiations, as a resolution is pivotal for the resumption of normal T-bill issuance and potential stabilization or improvement in short-term yields.
• Money-market fund investors, particularly those in funds with a narrow T-bill focus, should anticipate continued modest yields until supply constraints ease; funds with broader mandates for government-related assets may offer more resilience.
• Upon a debt-ceiling resolution, a significant increase in T-bill supply is expected, which could present opportunities to invest in new issues at potentially more favorable yields than those currently suppressed by scarcity.
• Consider the broader market implications of the approaching "X date", as heightened uncertainty could introduce volatility across various asset classes, warranting a cautious stance or a review of portfolio hedging strategies.
