Treasuries Lose Safe-Haven Status as Iran Conflict Exposes Fiscal Credibility Crisis
Institutional investors sold long-dated US bonds during geopolitical escalation, marking a historic inversion of flight-to-safety mechanics amid rising fiscal concerns
Institutional investors simultaneously exited long-duration US Treasuries and reduced equity hedges during the Iran military escalation in early March 2026, signaling a fundamental breakdown in the traditional safe-haven mechanics that have anchored global markets for decades. The 10-year Treasury yield surged to 4.26% by mid-March even as geopolitical risk spiked, inverting the expected flight-to-quality response and exposing deepening market anxiety over US fiscal sustainability.
When Safe Havens Turn Toxic
The market response to escalating Middle East tensions in early March defied six decades of precedent. Geopolitical conflict would typically cause Treasury prices to rise and yields to fall, but concerns about rising oil prices’ impact on inflation and the potential for a drawn-out conflict trumped the safe-haven bid, per CNBC. The benchmark 10-year Treasury yield rose 8 basis points to 4.044%, while the 30-year Treasury bond added more than 5 basis points to yield 4.688% in the initial days following US-Israel strikes on Iran.
US Treasurys exhibited “no signs of safe haven demand,” according to Tim Baker, macro strategist at Deutsche Bank. The 10-year yield was below the 4% level prior to the war, making the subsequent climb particularly jarring for institutional allocators who had positioned for traditional crisis dynamics.
As the crisis deepened, the benchmark 10-year note reached 4.26% by mid-March, the highest level seen in nearly a year, as investors aggressively priced in a new era of long-term inflation risk triggered by the escalating military conflict, according to analysis published by Market Minute.
“The bond market has said, ‘I’m more worried about inflation, than I am about growth, than I am about flight to quality.'”

The Fiscal Credibility Problem
The breakdown in traditional safe-haven behavior reflects mounting concern over US debt dynamics colliding with geopolitical stress. Bond vigilantes, concerned by a US national debt that surpassed $38.6 trillion in February, are demanding a higher term premium. Federal interest payments are projected to exceed the total national defense budget in FY2026 for the first time, and as yields rise, the cost of servicing $38.6 trillion in debt increases exponentially.
Deficit concerns are beginning to filter through prices for longer-maturity US government bonds, with investors charging more to hold longer-term government securities, known as the term premium, according to Goldman Sachs research.
A fiscal deficit projected to exceed $1.7 trillion in 2026 (over 6% of GDP), concerns over central bank independence and an upcoming Supreme Court decision on tariff authority all appear poised to keep the term premium elevated and the yield curve steep, according to analysts at Parametric Portfolio Associates.
The term premium represents additional compensation investors demand for holding longer-maturity bonds rather than rolling over short-term securities. A rising term premium during geopolitical crises—when investors historically sought long-duration bonds—signals fundamental doubt about the issuer’s fiscal trajectory. The current environment marks the first time since the 1970s oil shocks that US Treasury term premiums have widened during acute military conflict.
Foreign Holders Retreat
Foreign Treasury holdings in the United States decreased to $9,270.90 billion in December from $9,359.30 billion in November of 2025, according to Trading Economics data. Foreign investors, who have long been major buyers of US Treasury debt, have seen that demand become more uneven, with some foreign central banks, including the People’s Bank of China, selling off their holdings of Treasuries in substantial monthly quantities, per reporting by International Banker.
Investors selling long-dated government debt have started to demand a risk premium for investing in long-term bonds as insurance against inflation risks and against the trajectory of Fiscal Policy, which is considered too expansionary, according to Nicolò Bragazza, associate portfolio manager at Morningstar Wealth.
Duration Strategies Unwind
The crisis exposed institutional duration positioning as structurally misaligned with the new fiscal reality. Persistent pressure on long-term rates has limited the ability of duration-based strategies to protect portfolios in the event of a crisis. Managers who had extended duration in anticipation of Federal Reserve rate cuts found themselves offside as war-driven inflation fears collided with fiscal sustainability concerns.
Investors are growing worried that the Iran war will drive up expenditures and swell budget deficits, sparking a selloff in long-term government bonds that has driven the 30-year Treasury yield to close to 4.90%, the highest in a month, according to Bloomberg.
The Gold Rotation
As Treasuries failed, institutional capital flowed into alternative stores of value. Gold was valued at $5,184 per ounce on March 4, 2026, representing a $2,265 gain over the past year, according to Fortune. “The long-term trend of official reserve and investor diversification into gold has further to run,” said Natasha Kaneva, head of Global Commodities Strategy at J.P. Morgan, with the firm forecasting prices toward $5,000/oz by year-end 2026 and averaging $5,055/oz by the final quarter.
The combination of falling yields, elevated geopolitical stress and a pronounced flight-to-safety during severe downturns could create exceptionally strong tailwinds for gold, with investment demand via gold ETFs remaining a key driver, noted the World Gold Council.
| Asset | Direction | Change | Traditional Crisis Response |
|---|---|---|---|
| 10-Year UST Yield | ↑ | +32 bps | Should fall |
| 30-Year UST Yield | ↑ | +20 bps | Should fall |
| Gold | ↑ | ~5% | ✓ As expected |
| WTI Crude | ↑ | +66% | ✓ As expected |
| VIX | ↑ | Spike | ✓ As expected |
Credit Default Swap Signals
The derivatives market reflected the dual-risk pricing dynamic. While specific current CDS spreads for March 2026 were not immediately available in search results, historical context shows concerning patterns. During the 2023 debt ceiling crisis, spreads broadly rose to levels consistent with sovereign-debt default risk, with the term structure inverting as 1-year CDS approached 180 basis points while 10-year CDS reached 60 basis points, according to Lombard Odier.
Current CDS spreads on US sovereign debt show that even before the latest debt-ceiling renegotiations, fiscal concerns were weighing on the budget deficit, with the CDS market broadly elevated and the term structure losing its upward slope, declining from 20 to 15 basis points.
Equity Hedge Adjustment
Simultaneously, institutional investors reduced traditional equity protection strategies, reflecting reassessment of correlation assumptions. Market positioning for June maturity indicated traders were preparing for potential volatility by establishing deep out-of-the-money hedges at the 5000 level, with data collectively indicating increased institutional demand for downside protection following geopolitical developments in early January 2026, according to CME Group analysis.
Yet the traditional Treasury hedge component failed to perform. Many institutional investors note that traditional diversification of stocks and bonds may be insufficient in today’s environment of correlated risks, prompting consultants to build multi-layered risk mitigating frameworks that segment strategies into First Responders such as long-duration Treasuries, Second Responders like systematic trend-following, and Diversifiers such as global macro, according to Chief Investment Officer.
