Bond Markets Reprice As Inflation And Geopolitics Drive Q1 Volatility: Eurex Report
Global bond markets entered 2026 with expectations of monetary easing, but that narrative shifted during the first quarter as geopolitical tensions and renewed inflation concerns forced investors to reassess the outlook for interest rates. Data from Eurex shows that March became a turning point, with energy market disruptions triggering a repricing across fixed income markets.
The shift was driven primarily by developments in the Middle East, where escalating conflict translated into a supply shock that pushed energy prices higher and reintroduced inflation as the central concern for markets. That change reversed the disinflation trend that had begun to take hold at the end of 2025 and set off a broad sell-off in government bonds.
Energy Shock Reverses Disinflation Expectations
The link between geopolitics and inflation became the central theme of the quarter. As energy supply constraints emerged, inflation expectations moved higher across major economies, prompting investors to question how quickly central banks could cut rates. That shift had a direct effect on bond pricing, with yields rising across the curve in both the United States and Europe.
The reaction in fixed income markets showed how sensitive bond valuations remain to inflation signals tied to commodity markets. Rather than focusing on growth risks, investors adjusted positions based on the potential for sustained price pressures driven by energy costs. That adjustment led to a sell-off that affected both short and long maturities, though longer-dated yields moved more sharply.
This repricing also reflected a broader change in market assumptions. At the start of the quarter, expectations had leaned toward rate cuts, particularly in the United States. By March, those expectations were being reassessed as inflation risks returned to the forefront of macro thinking.
Central Banks Hold Rates As Markets Shift Expectations
During the quarter, both the Federal Reserve and the European Central Bank held policy rates unchanged, with the Fed at 3.75 percent and the ECB at 2.15 percent. Despite volatility, the ECB maintained that inflation remained in a stable position prior to the energy shock, suggesting that underlying trends had not fully reversed.
Markets, however, moved ahead of central banks. Earlier expectations for rate cuts in the United States were scaled back, while pricing in Europe began to reflect the possibility of further tightening. This divergence highlighted how regional dynamics can influence rate expectations differently, even when both economies face similar external shocks.
The gap between policy signals and market pricing is a recurring feature in periods of volatility. Investors tend to adjust positions based on forward-looking risks, while central banks move more gradually, relying on confirmed data. In this case, the energy-driven inflation shock pushed markets to react faster than policymakers.
Yields Rise And Curves Steepen
The bond sell-off led to higher yields across the curve, with German Bunds and U.S. Treasuries both reflecting the shift in inflation expectations. The increase was not limited to short-term rates, as long-term yields also moved higher, resulting in a steeper yield curve.
In the United States, the spread between two-year and ten-year yields reached 53 basis points, while in Germany the equivalent spread stood at 40 basis points. The steepening indicates that long-term inflation expectations played a larger role in pricing than short-term policy expectations during the quarter.
At the same time, euro area peripheral debt showed resilience. The spread between Italian 10-year bonds and German Bunds narrowed to 90 basis points, suggesting continued demand for higher-yielding assets even as overall rates increased. That behavior points to a search for yield that remains active despite volatility in core markets.
Trading Activity Expands As Volatility Increases
The shift in macro conditions was reflected in derivatives markets, where trading activity increased alongside volatility. Eurex reported an 18 percent year-on-year rise in volumes across long-term interest rate futures, with open interest also growing across major contracts.
Growth was particularly strong in German and Italian markets, where open interest increased by 20 percent and 31 percent respectively, while French contracts saw a 27 percent rise. The data suggests that investors used futures markets to reposition portfolios and manage risk as conditions changed rapidly.
Average trade sizes remained stable across key contracts such as Euro-Bund, Euro-Bobl, and Euro-Schatz futures, indicating that participation held up even as price movements intensified. Median trade sizes showed variation, reflecting a mix of tactical adjustments and risk management activity.
Liquidity conditions also shifted during the quarter. Market depth reached high levels during stable periods, with top-of-book sizes in Bund futures exceeding 1,000 lots. However, during contract roll periods and episodes of heightened geopolitical tension, liquidity tightened, with sizes dropping to around 190 lots as market participants reduced exposure.
Despite these fluctuations, execution remained stable. Trade impact increased during volatile periods but stayed within manageable ranges, suggesting that markets continued to absorb activity without significant disruption. This resilience points to the role of electronic trading and liquidity provision in maintaining function even under stress.
Outlook Shaped By Inflation And Geopolitical Risk
Looking ahead, the outlook for bond markets depends largely on how geopolitical developments evolve and whether energy prices stabilize. Inflation has reasserted itself as the main driver of policy expectations, and any further shocks could lead to additional volatility in rates markets.
Central banks are expected to maintain a cautious stance, balancing inflation risks against broader economic conditions. For investors, that creates an environment where positioning needs to adjust quickly to new information, particularly when external events shift the macro narrative.
The experience of the first quarter shows how rapidly expectations can change. A market that began the year anticipating rate cuts moved within weeks to question whether easing would be delayed or reversed. That pattern is likely to continue if geopolitical risks remain unresolved.
