The government bond safe haven failed during the March 2026 risk-off episode as stocks and long-term sovereign bonds fell together. Federal Reserve researchers said inflation pressure and the type of economic shock determine whether bonds protect a diversified portfolio.
The Federal Reserve staff note published October 16 examined the United States, euro area and United Kingdom. Authors Canlin Li and Emre Yoldas stressed that the findings are staff analysis, not a monetary-policy decision.
Government Bond Safe Haven Breaks in March
During the March 2–31 risk-off episode, U.S. stocks fell 5.13% while the estimated return on 10-year government bonds was negative 1.97%. Euro-area stocks lost 6.51% and bonds lost 2.04%, while U.K. stocks fell 5.60% and bonds declined 3.79%.

The chart uses the Federal Reserve’s accessible data rather than estimating missing observations. It shows why investors should not assume that government debt will automatically offset every equity selloff.
Inflation Changes the Government Bond Safe Haven
When inflation is close to target, central banks have more room to cut rates after a negative growth shock. Falling yields can then lift bond prices while equities weaken, supporting the government bond safe haven.
The relationship changes when an adverse supply shock raises energy prices and inflation expectations. Investors may anticipate tighter policy even as growth deteriorates, allowing stock prices and bond prices to fall together.
The researchers found that higher-than-expected U.S. inflation has raised 10-year Treasury yields about three times more since 2021 than before the pandemic. The spillover to euro-area and U.K. yields also became statistically significant in the later period.
What Bond Investors Should Monitor
Investors should track near-term inflation expectations, energy-driven supply shocks and the sensitivity of long yields to inflation releases. Fusion Market News’ October FOMC guide outlines the next U.S. policy checkpoint, while the fed funds liquidity analysis covers funding-market signals.
Cross-border demand can also affect Treasury pricing, as shown in the latest foreign capital inflow report. None of these measures guarantees a hedge, but together they show whether inflation risk or flight-to-quality demand is dominating markets.
