The recent downgrade of the US credit rating by Moody's from AAA to Aa1 has brought renewed attention to the nation's fiscal stability.

The downgrade coincides with a critical report from researchers at Yale University, which scrutinizes the growing fiscal imbalance in the United States.

Current fiscal challenges include a significant annual budget deficit exceeding $2 trillion, which persists despite a period of strong economic growth and low unemployment under the Biden administration.

This deficit has led to net interest costs consuming an estimated 18% of federal revenue.

The Yale report warns that the proposed fiscal legislation under consideration by Congress could exacerbate the debt issue significantly.

Specifically, it projects that the legislation could add $3.4 trillion to the national debt from 2025 to 2034 and a staggering $15.3 trillion from 2025 to 2055. Should these provisions become permanent rather than temporary, the nation’s debt-to-GDP ratio could reach 200% by 2055, surpassing only countries like Sudan and Japan, while a debt-to-GDP ratio of 180% would place the US in a predicament similar to that of Venezuela or Singapore.

Furthermore, the report notes that the fiscal plan does not consider the optimistic revenue projections anticipated from tariffs under the Trump Administration.

Even factoring in these tariff revenues as they stood in May 2023, the new debt incurred would total $913 billion from 2025 to 2034, and $5.1 trillion from 2025 to 2055.

The Committee for a Responsible Federal Budget, a nonpartisan group advocating for reduced deficits, also emphasizes the potential fiscal implications of the new legislation.

They estimate that the fiscal imbalance for 2027, the first full year of policy implementation, could increase by nearly $600 billion, equating to 1.8% of GDP. This figure reflects approximately $770 billion in new borrowing against $180 billion in offsets.

The legislative proposals include various tax provisions, such as MAGA accounts that would allow parents to transfer more money to their children free of tax, the elimination of a special tax on firearms, and increased limits on state and local tax deductions up to $30,000.

Additionally, the bill incorporates several campaign promises from President Trump, including a lack of taxes on tips and overtime pay.

Despite the alarming fiscal outlook, analysts caution that worsening debt ratios may not present an immediate funding crisis for the US Treasury.

Bond investment mandates do not universally require AAA ratings for US Treasury bonds, and many central banks continue to regard US Treasuries favorably due to their liquidity.

Some analyses suggest it is unlikely that the downgrade will trigger forced bond sales, although it could impact market confidence.

The US retains a high credit rating, and Treasury bonds remain considered the safest dollar-denominated asset.

The continuing strength of US capital markets, the dollar's status as a reserve currency, and the considerable wealth of American households support the notion that the US will continue to meet its debt obligations.

With the White House's budget proposal currently facing a slim majority in the House of Representatives, some Republican legislators are demanding further spending cuts, while others express reluctance to reduce Medicaid funding.

A Congressional Budget Office study estimates that the proposed legislation could cause an additional 8.6 million Americans to be uninsured by the end of the decade while cutting federal healthcare spending by over $700 billion during the same timeframe.

The fiscal landscape of the US continues to prompt serious discussions as stakeholders navigate the implications of proposed legislative changes.
