Assessing the Risk of a US Default: An Analysis of Treasury Bill Markets

 

Introduction

The ongoing negotiations over the US statutory debt ceiling have created uncertainty in the Treasury bill markets. While there has been a more positive tone in the discussions between the White House and Congressional leadership, investors remain cautious. This article delves into the current situation and provides an analysis of the key indicators to watch for insights into the risk of a US default.

1. The Bills Curve

Investors closely monitor the yield curve for Treasury bills, particularly those due shortly after the US reaches its borrowing capacity. Higher yields on these securities indicate heightened concerns about default risk. Presently, significant yield premiums are observed for securities maturing in early June, the period when the US government is most at risk of non-payment. However, even if the June danger zone is surpassed, the risk of default persists throughout the US summer if no legislative resolution is reached.

2. X-Date Predictions

Estimations of the government's exhaustion of funding options, referred to as the X-date, vary among analysts. While the administration suggests a potential shortfall as early as June, Wall Street forecasters have adjusted their estimates to align more closely with the government's guidance. Some analysts remain hopeful that the Treasury can extend its resources until late summer, considering factors such as cash flows, tax receipts, and spending projections.

3. The Cash Balance

The Treasury's ability to meet its obligations hinges on its cash balance. Daily fluctuations occur based on spending, tax receipts, debt repayments, and borrowing activities. If the cash balance nears zero, it could pose a problem. Fortunately, the US government experienced a modest increase in available funds at the end of last week, offering temporary relief as it strives to secure funding while resolving the debt-limit impasse. Attention should also be given to the extraordinary measures employed by the Treasury to maximize its borrowing capacity. These accounting maneuvers have already been utilized significantly, leaving approximately $92 billion as of the middle of last week.

4. Insuring Against Default

In addition to Treasury bills, credit-default swaps (CDS) for US government debt serve as indicators of default risk. CDS instruments function as insurance for investors in the event of non-payment. Notably, the cost of insuring US debt has risen above that of countries such as Greece, Mexico, and Brazil, which have experienced multiple defaults and possess lower credit ratings than the US.

Conclusion

While negotiations between the US government and Congressional leaders offer some hope, the risk of a US default has not been completely alleviated. Treasury bill markets continue to exhibit caution, with elevated yields observed for securities maturing in early June. Monitoring the bills curve, X-date predictions, the cash balance, and CDS pricing provides insights into the level of concern among investors and the potential timeline for a resolution. While the chances of a default are considered remote, navigating the upcoming political challenges remains critical to ensuring the stability of the US economy and financial markets.
