Political Instability and the U.S. Markets: Navigating Risks and Opportunities in Defense and Safe-Haven Assets

A line chart illustrating the inverse relationship between U.S. political stability indices (2023–2025) and gold prices, with annotations highlighting key geopolitical events such as the 2025 government shutdown and regional conflicts.

The United States, long a beacon of economic and political stability, now finds itself in a precarious position. According to the World Bank's political stability index, the nation's Political Stability and Absence of Violence/Terrorism index ranked at 35.07% in 2023, a stark decline compared to its historical standing. This erosion of stability, driven by domestic polarization, civil unrest, and foreign influence, has sent ripples through financial markets, reshaping investment strategies and asset allocations. For investors, the question is no longer whether political instability matters-it is how to navigate its consequences.

The Defense Sector: A Fractured Defensive Edge

The defense sector, traditionally a haven during geopolitical turbulence, has shown unexpected fragility in 2025. Data from the U.S. Department of Defense and market analyses reveal that major contractors like Lockheed Martin and Northrop Grumman have underperformed, with stock values dropping by 10% year-to-date, according to an MSM Times analysis. This decline is attributed to rising production costs, policy uncertainty, and a shift in global defense spending dynamics. European firms such as Germany's Rheinmetall and South Korea's Hanwha Aerospace have outperformed their U.S. counterparts, gaining 30% and 15% respectively, as regional governments diversify away from American suppliers, per Morningstar data.

The 2025 government shutdown further exposed the sector's vulnerabilities. While traditional defense manufacturers held steady, government services contractors like CACI International surged by 3.28% amid expectations of post-shutdown catch-up spending, according to a YCharts analysis. This divergence underscores a critical shift: investors are no longer treating the defense sector as a monolith. Instead, they are parsing subsectors based on exposure to policy risks, operational flexibility, and regional demand.

Safe-Haven Assets: Gold's Resurgence and the Dollar's Waning Dominance

As political instability mounts, safe-haven assets have gained renewed traction. Gold prices, for instance, have reached record levels in 2025, with investment demand surging 170% year-over-year, according to an Observer analysis. Historical correlations between geopolitical risk and gold prices remain robust: each 100-unit increase in the Geopolitical Risk Index corresponds to a 2.5% rise in gold prices, per a World Gold Council analysis. The 10-Year U.S. Treasury yield, meanwhile, has dipped to 4.12%, reflecting a flight to safety during the government shutdown, according to the YCharts analysis.

Yet the U.S. dollar's dominance is showing cracks. The Dollar Index Spot has fallen nearly 9% year-to-date, signaling a loss of confidence in the greenback as a traditional safe-haven currency; the Observer piece likewise notes growing investor interest in alternatives. Investors are increasingly diversifying into non-U.S. assets, including European government bonds and alternative commodities. This shift is not merely a reaction to short-term volatility but a recalibration of long-term portfolio strategies in an era of persistent uncertainty.

Strategic Implications for Investors

The interplay between political instability and market dynamics demands a nuanced approach. For defense stocks, the key lies in identifying firms with diversified revenue streams and exposure to high-growth technologies like AI and cybersecurity. As noted by BlackRock's Geopolitical Risk Dashboard, companies with strong R&D pipelines and regional partnerships are better positioned to weather policy shifts.

In the safe-haven space, gold remains a cornerstone, but its role is evolving. With gold ETF holdings experiencing sharp fluctuations, investors must balance its allure with hedging strategies that account for liquidity risks. Similarly, the U.S. Treasury market's appeal is waning, prompting a reevaluation of currency allocations and the inclusion of non-traditional safe-havens like Swiss francs or Japanese yen.

Conclusion

Political instability is no longer a peripheral concern for U.S. markets-it is a defining feature of the investment landscape. The defense sector's fragmentation and the reconfiguration of safe-haven preferences highlight the need for agility and diversification. As the U.S. grapples with domestic and global challenges, investors must remain attuned to the evolving interplay between governance, markets, and macroeconomic forces. In this environment, the winners will be those who adapt-not just to the risks, but to the opportunities they create.
