Fed Note: Bond Safe-Haven Role Shifts With Inflation Pressures
A Federal Reserve note finds government bonds' hedging property depends on inflation pressures and the type of economic shock, with post-2021 dynamics differing from the low-inflation era.
What you need to know
A Federal Reserve FEDS Note argues that government bonds' safe-haven property is not fixed but depends on the inflation environment and the mix of economic shocks. Post-2021, negative stock-bond correlations in the U.S., euro area and U.K. reflect inflationary pressures and adverse supply shocks rather than a fundamental change in bond characteristics.
- Stock-bond correlations turned negative post-2021 in the U.S., euro area and U.K., the note says.
- Post-2021, higher-than-expected U.S. inflation news raises U.S. 10-year yields about three times as much as in 2000-2019.
- The note says the post-2021 deterioration in bonds' hedging property reflects the economic environment, not a fundamental change in bond characteristics.
What the note finds
The FEDS Note, published October 16, 2026, examines stock-bond correlations and inflation forecasts across the United States, the euro area and the United Kingdom. It reports that correlations were deeply negative in the early 1990s, positive for most of 2000-2021, and negative again in recent years. The authors link these shifts to three inflation regimes rather than to a permanent change in how government bonds trade.
The note concludes that bonds provide reliable hedging when inflation is near target and expectations are anchored, because central banks can ease in response to adverse shocks. When inflationary pressures build and inflation expectations are at risk, adverse supply shocks can push investors to expect tighter policy, undermining the traditional flight-to-quality dynamic.
Event-study evidence
The note's event study estimates asset responses to inflation surprises from Bloomberg indices. During 2000-2019, bond yields showed modest sensitivity to inflation news and stock returns did not react significantly. Post-2021, a higher-than-expected U.S. inflation surprise raised U.S. 10-year yields about three times as much as before and also significantly lifted euro-area and U.K. yields. Stock returns fell significantly on own-country inflation surprises in the post-2021 period.
The authors attribute the amplified yield sensitivity to inflation news as the central mechanism breaking bonds' traditional safe-haven dynamics. They suggest that if inflationary pressures abate and adverse supply shocks become less frequent, bonds' hedging property is likely to improve.
Why have government bonds stopped hedging stock losses as reliably?
A Federal Reserve note says bonds hedge when inflation is near target and expectations are anchored. With inflationary pressures higher after 2021, adverse supply shocks can raise expectations of tighter policy, so stocks and bonds can fall together.
