Investors see worsening US deficit outlook as tax bill heads to Senate

Investors are concerned that the U.S. debt could increase further as a tax and spending bill moves through the Senate, potentially leading to higher bond yields; the House version of the bill is projected to add $3.8 trillion to the federal debt over the next decade. The market's sensitivity to the U.S. debt profile was recently highlighted by Moody's downgrade of the U.S. sovereign credit rating. While some investors anticipate growth from tax cuts and tariffs, others are skeptical, fearing that increased government debt funding costs could offset any potential benefits.

Analysis

Investor apprehension is growing regarding the U.S. fiscal outlook, primarily driven by a proposed tax and spending bill anticipated to significantly increase the national debt, which currently stands at $36.2 trillion. The House version of the bill alone is projected by the Congressional Budget Office to add approximately $3.8 trillion to the debt over the next decade. This development follows Moody's recent downgrade of the U.S. sovereign credit rating on May 16, which has heightened market sensitivity to the nation's debt profile. Consequently, long-dated U.S. bonds have experienced pressure, evidenced by a tepid response to a 20-year auction and the 30-year bond yield reaching its highest level since October 2023. Market participants, such as Brian Nick of NewEdge Wealth, express concern that as the bill progresses through the Senate, spending cuts may be reduced and stimulus added, further exacerbating deficit growth and potentially leading to higher bond yields and a steeper yield curve. While the Trump administration emphasizes $1.6 trillion in spending cuts and projects $2.5 trillion in new revenue from economic stimulus, analysts like Mohit Mittal at PIMCO suggest the final bill could add $50 to $75 billion more per year to the deficit than markets anticipated. Morgan Stanley notes potential benefits for U.S. companies with high capital expenditure in sectors like industrials, communications services, and energy, and estimates tariffs could generate $2 trillion in revenue over 10 years, though this is subject to ongoing trade talks. However, strategists like Naomi Fink from Nikko Asset Management caution that if tax cuts don't stimulate demand faster than they escalate government debt funding costs, the intended benefits may not materialize. Investors like Thanos Bardas at Neuberger Berman find the steeper yield curve attractive for long-term returns, while others like Mike Reynolds at Glenmede believe yields have not yet peaked. The legislative process, particularly the Senate's actions post-Memorial Day recess and President Trump's July 4 target for the bill, remains a key focus, with lawmakers expected to monitor both voter sentiment and market reactions, especially concerning consumer lending rates.

Key Decisions for Investors

• Investors should anticipate continued upward pressure on long-dated U.S. bond yields and a steeper yield curve due to increased deficit concerns stemming from the proposed fiscal legislation, warranting a cautious stance on duration risk.
• Monitor developments in the Senate closely, as modifications to the House bill's spending cuts and stimulus provisions could significantly alter deficit projections and market reactions, with softer economic data potentially reducing the appetite for fiscal austerity.
• Evaluate sector-specific exposures, noting potential beneficiaries like U.S. industrials, communications services, and energy companies with high capital expenditures, but weigh these against the broader macroeconomic risks of rising borrowing costs and increased fiscal uncertainty.
• Given the heightened sensitivity to the U.S. debt profile and the recent sovereign credit downgrade, investors should demand adequate risk premia for holding U.S. debt, particularly longer-maturity instruments.
