The European Central Bank left its main interest rate unchanged at 2.25% on Thursday, a decision that broadly matched market expectations. Even so, attention quickly turned to what comes next, with traders increasingly looking at the possibility of a September rate hike.
That shift in expectations is tied to concerns that higher energy prices could keep inflation under pressure across the euro area. If energy costs continue to rise, investors appear to believe the ECB may need to respond with tighter policy later this year rather than stay on hold for long.
ECB President Christine Lagarde added to that focus by saying the bank expects inflation to remain well above target until the first half of 2027. That outlook suggests policymakers still see price pressures lasting longer than many had hoped, even after choosing not to move rates at this meeting.
For markets, the key question is whether the recent energy price spike becomes a temporary shock or a more persistent inflation problem. The answer is likely to shape expectations for the ECB's next decisions and for borrowing costs across Europe in the months ahead.
