Two-Year Bunds Underperform After ECB Hike as 3% Rate Risk Grows
The September hike and another 25bp by December were already close to fully priced. The post-meeting asymmetry sits beyond 2.75%: the two-year German yield rose about 9bp versus roughly 2bp at 10 years, while markets assigned a 36% chance to 3% by Christmas.
The European Central Bank raised its deposit rate 25 basis points to 2.5% on September 10, delivering a move the market had largely discounted in advance. The day before the meeting, traders were already pricing the deposit rate at about 2.73% by December, leaving little yield upside from simply delivering one additional 25bp increase after September.
The meeting barely changed that base case. LSEG pricing after the decision put the probability of another hike by December 17 at 89%. The live risk shifted further out the distribution: markets assigned a 36% probability that the deposit-rate yield reaches 3% by Christmas.
For a euro-rates portfolio, the mechanism is higher expected short-term financing costs if the path extends beyond 2.75%. The two-year German Bund yield rose about 9bp on the day while the 10-year yield rose about 2bp. On those reported moves, the 2s10s yield gap narrowed by roughly 7bp. Front-end duration absorbed much more of the repricing than the 10-year sector.
The ECB's new forecasts give the 3% tail a fundamental basis. Staff kept 2026 headline inflation at 3.0% and projected inflation excluding energy and food at 2.6% in 2027 and 2.3% in 2028, a path that keeps short-term financing-cost pressure alive. Growth was also revised higher, to 0.9% in 2026 and 1.4% in 2027, giving the Governing Council more room to raise financing costs again if the Middle East energy shock migrates into wages and services.
That transmission concern predates this meeting. The ECB's July account said euro-area risk-free yields had risen through both real rates and inflation compensation after the Middle East conflict intensified, with inflation compensation more important at shorter horizons. September did not create the second-hike trade; it left the market with less reason to remove it and a non-trivial tail beyond it.
The position for a euro duration manager is now asymmetric. A move to 2.75% by December is already embedded in the front end. Further losses require the distribution to migrate toward 3%, which needs broader evidence that the energy shock is becoming persistent underlying inflation. The 7bp relative move between reported two- and 10-year yield changes shows where the market is charging for that risk today.
