Traders see September rate hike as European Central Bank mulls energy price spike

The European Central Bank held its main interest rate at 2.25% on Thursday, matching market expectations, while President Christine Lagarde warned inflation will remain "well above target" until the first half of 2027. Traders are now pricing in a September rate hike as energy price spikes threaten to keep upward pressure on prices across the eurozone.

The decision keeps the deposit facility rate unchanged after the ECB's previous tightening cycle. Lagarde's extended inflation timeline—pushing normalization nearly three years out—marks a significant shift from earlier ECB projections and signals the central bank's struggle to anchor price pressures despite holding rates at restrictive levels.

Energy costs remain the primary concern, with recent spikes complicating the ECB's inflation fight. The gap between current price pressures and the ECB's 2% target appears wider and more persistent than policymakers anticipated earlier this year.

Markets are repricing ECB terminal rate expectations, with September futures now reflecting increased odds of another 25-basis-point hike. The euro faces pressure from prolonged inflation uncertainty and the prospect of tighter monetary policy extending deeper into 2025.
