Global Demand for US Treasuries Amid Geopolitical Uncertainty: Assessing Resilience in a Fractured World

The global financial landscape in 2025 is marked by a seismic shift in the perceived safety of US Treasuries. Once the bedrock of global capital markets, these instruments are now facing a reckoning. The confluence of geopolitical fragmentation, fiscal overreach, and policy uncertainty has eroded the "convenience yield" that historically made Treasuries the default refuge for investors. This article examines the forces reshaping demand for US debt, the evolving role of alternative safe-haven assets, and the strategic implications for investors navigating a fractured world.

The Erosion of Trust: Fiscal and Geopolitical Catalysts

The US debt-to-GDP ratio has surged to 123% in 2025, a level that has triggered a recalibration of risk perceptions among global investors. The May 2025 downgrade of the US sovereign credit rating by Moody's from Aaa to Aa1 underscored concerns about fiscal sustainability. This move was not an isolated event but part of a broader narrative of declining confidence in the US's ability to manage its debt burden.

Geopolitical tensions have further compounded these concerns. The "Liberation Day" tariff announcements, coupled with the specter of Trump 2.0-style protectionism, have introduced policy volatility that contradicts the stable, predictable environment Treasuries are meant to represent. Central banks and sovereign wealth funds—key holders of Treasuries—are now diversifying their portfolios, reducing exposure to US debt in favor of alternatives perceived as less entangled in geopolitical risk.

A striking indicator of this shift is the breakdown of the historically positive correlation between US Treasury yields and the US dollar. In 2025, rising yields have coincided with a weakening dollar, a pattern more typical of emerging markets. This divergence signals that investors are interpreting higher yields not as a sign of economic strength but as a reflection of systemic risk—a stark departure from prior decades.

The Rise of Alternative Safe-Havens

As confidence in Treasuries wanes, investors have turned to alternative safe-haven assets. The Japanese yen (JPY) and Swiss franc (CHF) have outperformed during periods of market stress, maintaining negative equity betas and delivering modest returns during equity downturns. Gold, long a barometer of systemic risk, has surged by over 9% in early 2025 amid Treasury market instability and a weakening dollar.

Short-duration sovereign bonds have also gained traction. These instruments, less sensitive to inflation and interest rate volatility, offer a pragmatic hedge in an environment of rising yields. The 60/40 portfolio model, which relied heavily on long-duration Treasuries for downside protection, is increasingly being replaced by diversified 60/20/20 allocations that include gold, safe-haven currencies, and shorter-dated bonds.

Regional Dynamics and Central Bank Behavior

The regional breakdown of foreign holdings reveals a fragmented picture. Asia remains the largest holder of US Treasuries, with Japan ($1.135 trillion) and China ($756.3 billion) as dominant players. However, China's holdings have declined for four consecutive months, reflecting a strategic rebalancing of its foreign exchange reserves.

Europe's role is equally significant. The United Kingdom, with $809.4 billion in holdings, has emerged as the second-largest holder of US debt, overtaking China in early 2025. This growth is partly attributed to custodial flows, but it also highlights Europe's continued reliance on Treasuries despite growing fiscal concerns.

Strategic Implications for Investors

For investors, the key takeaway is clear: the era of relying solely on long-duration Treasuries as a safe-haven asset is over. A regime-aware approach is now essential. Here's how to adapt:

1. Diversify Defensive Allocations: Blend traditional Treasuries with alternative safe-havens like gold, JPY, and CHF. Short-duration sovereign bonds should also be considered to mitigate duration risk.
2. Monitor Fiscal and Policy Signals: Track inflation volatility, debt sustainability metrics, and central bank policy shifts. These factors will increasingly drive correlations between risky assets and safe-havens.
3. Rebalance Portfolios Dynamically: A static 60/40 model is no longer sufficient. Investors should adjust allocations based on real-time macroeconomic signals, such as rising geopolitical tensions or unexpected credit rating changes.

Conclusion: A New Normal in Safe-Haven Investing

The 2025 landscape underscores a fundamental shift in global capital flows. While US Treasuries retain their role in liquidity and collateral markets, their status as the dominant safe-haven asset is being challenged. Investors must now navigate a world where geopolitical fragmentation, fiscal uncertainty, and evolving market dynamics demand a more nuanced, adaptive approach. The future of safe-haven investing lies in diversification, flexibility, and a keen awareness of the interconnected forces shaping global markets.
