Why U.S. budget deficits could soon go from stock-market friend to foe

Concerns are rising that widening U.S. budget deficits, exacerbated by the proposed Republican budget plan, could negatively impact U.S. stocks as bond markets react with rising Treasury yields, with the 30-year yield exceeding 5%. Some analysts draw parallels to the market turmoil in the U.K. following unfunded spending plans, while others, like Capital Economics, suggest the deficit impact may be offset by new tariffs, leaving it near 6% of GDP. Wednesday saw U.S. stocks decline, with the S&P 500 down 1.3%, following a weak 20-year Treasury bond auction.

Analysis

Growing concerns center on the potential for wide U.S. budget deficits, potentially exacerbated by the proposed Republican budget plan, to negatively impact U.S. equities. This apprehension is fueled by the bond market's adverse reaction, evidenced by rising Treasury yields; notably, the 30-year Treasury yield has surpassed 5%, a level historically correlated with stock market distress, such as the correction in September-October 2023. This trend isn't isolated to the U.S., as yields on long-dated Japanese government bonds have also reached multi-decade highs. The market impact was visible on Wednesday, with the S&P 500 declining 1.3% to 5,863, the Nasdaq Composite falling 1.1% to 18,937, and the Dow Jones Industrial Average dropping 1.9% to 41,890, following a disappointing 20-year Treasury bond auction. Joseph Wang of Fedguy.com warns that the upcoming spending bill, typically equity-positive, could have the opposite effect, referencing the U.K.'s market turmoil in 2022 under Liz Truss due to unfunded fiscal plans as a more fitting comparison than Germany's recent deficit-fueled equity rally. Compounding these concerns, the Federal Reserve remains on hold, with expectations for rate cuts continually deferred, unlike the previous year when Fed signals helped stabilize markets. However, Capital Economics offers a counterpoint, suggesting the budget plan might not significantly increase the deficit, projecting it to remain near 6% of GDP due to new tariffs potentially offsetting tax cuts, though the debt-to-GDP ratio is still forecast to reach nearly 120% by 2034.

Key Decisions for Investors

• Investors should closely monitor developments in U.S. fiscal policy, particularly the progress of the Republican budget plan and its perceived impact on the federal deficit, as these are key drivers of current market anxiety.
• Heightened attention should be paid to Treasury yield movements, especially if the 30-year yield sustains levels above 5%, a historical precursor to increased equity market volatility and potential downturns.
• Consider re-evaluating equity allocations and exploring defensive or hedging strategies if fiscal concerns escalate and bond yields continue to rise, while also monitoring the effectiveness of proposed offsetting measures like tariffs, which could mitigate some downside risk.
