Assessing the Impact of Rising Inflation and Government Shutdown on US Equity Markets

The U.S. equity market is navigating a complex macroeconomic landscape in late 2025, marked by persistent inflation and the looming threat of government shutdowns. With the Federal Open Market Committee (FOMC) projecting inflation to remain at 3.0% for the year and gradually decline to 2.0% by 2028, according to the FOMC projections, investors must contend with the dual pressures of elevated borrowing costs and fiscal policy uncertainty. Simultaneously, the 2025 government shutdown-furloughing millions of federal workers and disrupting critical economic data-has introduced volatility, with each week of shutdown estimated to reduce annualized GDP growth by 0.1%, according to a White House analysis. This analysis explores how these forces are reshaping sector dynamics and outlines strategic rotations and risk mitigation approaches for investors.

Macroeconomic Headwinds: Inflation and Fiscal Fragility

The U.S. inflation rate, while easing from multi-decade highs, remains above the Federal Reserve's 2.0% target. This environment favors sectors with pricing power and low sensitivity to interest rates. Meanwhile, the fiscal outlook is increasingly precarious, with public debt projected to reach 106% of GDP by 2027 and 200% by 2047 under current policies, as highlighted in the White House analysis. Rising interest rates have exacerbated this challenge, with net interest payments in fiscal year 2025 already exceeding $841 billion-surpassing Medicaid spending and second only to Social Security, according to Deloitte Insights. These trends underscore the need for portfolios to prioritize resilience against both inflationary pressures and fiscal shocks.

Sector Rotation: Winners and Losers in a Deteriorating Environment

Historical data reveals distinct patterns in sector performance during overlapping periods of inflation and government shutdowns. For instance, during the 2013 and 2018–2019 shutdowns, energy, utilities, and consumer staples outperformed, while technology and consumer discretionary sectors lagged, according to a YCharts analysis. This divergence reflects the inherent characteristics of each sector: energy and utilities benefit from inflation due to their ability to pass costs to consumers and their essential nature, whereas growth-oriented tech stocks face valuation headwinds from higher discount rates, as noted by PurelyInvesting.

The 2025 shutdown has further highlighted these dynamics. Defense manufacturers like Lockheed Martin and Raytheon have remained stable, with the defense sector averaging a mere -0.01% decline, the White House analysis finds. In contrast, government services contractors-such as CACI International and Booz Allen Hamilton-have surged, driven by expectations of catch-up spending post-shutdown, according to the same White House analysis. Similarly, the technology sector has shown resilience, with the XLK ETF gaining 0.98% on the first day of the 2025 shutdown, reflecting continued private-sector demand reported in that analysis.

However, not all sectors have fared equally. Financials, for example, underperformed during the 2025 shutdown, with the XLF ETF falling 0.89% as economic uncertainty weighed on banking stocks; the White House analysis attributes this to delayed data releases and elevated policy uncertainty. This aligns with historical trends, where financials often struggle during periods of fiscal instability due to reduced lending activity and delayed regulatory data, as discussed by Deloitte Insights.

Risk Mitigation: Navigating Uncertainty

To mitigate risks in this environment, investors should adopt a dual strategy: hedging against inflation and insulating portfolios from shutdown-related volatility. Defensive sectors like utilities and healthcare-historically up 50% of the time during shutdowns per Deloitte Insights-offer stability. For example, the healthcare sector (XLV) surged 3.09% on the first day of the 2025 shutdown, underscoring its appeal as a safe haven in the White House analysis.

Additionally, investors should consider inflation-linked assets such as Treasury Inflation-Protected Securities (TIPS) and gold, which have gained traction as foreign central banks diversify away from U.S. Treasuries amid rising tariffs and geopolitical tensions, according to Deloitte Insights. Gold's appeal has been further bolstered by the U.S. dollar's weakening against the yen and euro, a trend linked to shifting investor sentiment discussed by Deloitte Insights.

For active investors, opportunities exist in sectors poised to benefit from post-shutdown rebounds. Government services contractors, for instance, often see short-term gains as delayed contracts are fulfilled. Similarly, energy and materials sectors-driven by commodity price inflation-remain attractive, particularly as global supply chains remain fragile.

Conclusion: Strategic Adaptation in a Shifting Landscape

The interplay of rising inflation and fiscal instability demands a proactive approach to portfolio management. While the S&P 500 has historically shown resilience during shutdowns-averaging a slight gain since 1976, per Deloitte Insights-sector-level impacts remain pronounced. By rotating into inflation-protected sectors like energy, utilities, and consumer staples, while hedging against fiscal shocks through defensive assets and active sector bets, investors can navigate this turbulent environment with greater confidence.

As the 2025 shutdown underscores, the key to success lies in agility: anticipating macroeconomic shifts, leveraging historical patterns, and maintaining a diversified, adaptive strategy.
