ECB raises interest rates to 2.5% and warns Middle East conflict will keep inflation elevated into 2027

The European Central Bank raised its main interest rate by 25 basis points to 2.5% on September 10, 2026, marking the highest rate since March 2025. ECB President Christine Lagarde said in the decision that "we believe inflation will be longer lasting than we had anticipated," citing Middle East conflict as a driver of sustained energy price pressures. Lagarde said that "headline inflation is expected to return to around target towards the end of 2027, supported by the effects of higher interest rates," according to Guardian reporting. This represents a significant shift from previous ECB forecasts and signals that conflict-driven energy shocks have altered the central bank's inflation timeline. The ECB simultaneously lifted its forecast for eurozone economic growth in 2026 to 0.9%, up from 0.8% in June, according to Guardian reporting. The bank now expects inflation to average 3% in 2026. Lagarde warned that food inflation, which had remained low at 1.2%, was likely to increase in response to higher oil and gas prices, according to Guardian reporting. Energy markets have moved sharply in recent days. Brent crude oil passed $105 a barrel before settling around $104.50, representing a 3.3% rise on the day of the rate decision, according to Guardian reporting. British natural gas prices rose above 203 pence per therm, the highest level since December 2022, per Guardian reporting. The Dutch wholesale gas price passed 80 euros per megawatt hour for the first time since January 2023, with the front-month contract trading 3.4% higher at 82.56 euros per megawatt hour, according to the same reporting. These energy moves coincide with Middle East escalation. BBC reporting also noted that Iran-aligned Houthi forces were reported to have seized Yemen's port of Mokha, a key Red Sea port. The ECB's decision immediately rippled through government bond markets. Germany's 30-year government bond yield rose 2.5 basis points to 5.08%, the highest since December 2003, according to Guardian reporting. The German 10-year yield hit 3.45%, the highest since April 2011, per the same source. France's 10-year government bond yield reached 4.344%, the highest since October 2008, according to Guardian reporting. In the United Kingdom, the yield on benchmark 10-year government bonds hit 5.36%, the highest since August 2007, according to Guardian reporting. BBC reporting noted that yields on UK 20- and 30-year bonds reached levels not seen since 1998. EU gas storage is currently at 67% capacity, well below the five-year average of 84%, according to Guardian reporting. In the UK, Ofgem's price cap is due to increase by 3.6% at the start of October, with the next change scheduled for January, per BBC reporting. Across the Atlantic, the U.S. 10-year Treasury yield rose to a three-year high. U.S. Treasury Secretary Scott Bessent announced that the U.S. would buy back $6 billion worth of government debt to alleviate a sell-off in the bond market, according to Guardian reporting. However, the size of the buyback package was considered inadequate by bond market participants, per the same reporting.
