S&P affirms US credit rating as tariff revenue offsets fiscal concerns

S&P Global affirmed its AA+ long-term and A-1+ short-term credit ratings for U.S. debt, maintaining a stable outlook, predicated on expectations that robust tariff revenue will help offset fiscal pressures and the U.S. economy's continued resilience. While the agency noted the fiscal deficit grew significantly in July despite increased customs receipts, it anticipates bipartisan resolution of issues like the debt ceiling. However, S&P flagged potential downgrade risks over the next 2-3 years if deficits increase due to political inability to contain spending or manage tax changes, or from concerns over long-term policymaking and Federal Reserve independence, yet also outlined conditions for a potential upgrade based on fiscal improvement.

Analysis

S&P Global has affirmed the U.S. long-term credit rating at AA+ with a stable outlook, signaling near-term confidence in the nation's economic resilience. The agency's rationale hinges on the expectation that a significant increase in tariff-related income, which surged to $27.7 billion in July from $7.1 billion a year prior, will help offset fiscal slippage from tax cuts and spending increases. However, this optimism is tempered by the acknowledgment that the government deficit still expanded by nearly 20% to $291 billion in July, with the new tariff revenue making little immediate impact on the budget. S&P explicitly warns of a potential downgrade within the next two to three years if political gridlock prevents the containment of rising deficits. Furthermore, the agency flags significant non-financial risks, including doubts over long-term policymaking and political pressure on the Federal Reserve's independence, which could undermine institutional stability and creditworthiness.

Key Decisions for Investors

• Treat the AA+ rating affirmation as a near-term stabilizing factor for U.S. sovereign debt, but recognize the stable outlook is conditional and does not eliminate underlying fiscal risks.
• Closely monitor the trajectory of the U.S. fiscal deficit and any political gridlock concerning spending or the debt ceiling, as S&P has explicitly flagged these as triggers for a potential downgrade within a 2-3 year timeframe.
• Factor in heightened political risk, particularly concerning challenges to Federal Reserve independence, as this could introduce significant volatility and uncertainty into monetary policy expectations.
