The ECB's September 10 decision to raise its key rates by 25 basis points to a 2.50% deposit facility rate addressed persistent inflation pressures tied to Middle East energy shocks, with staff projections showing headline inflation at 3.0% for 2026. Traders assign 93% probability to no change at the late-October meeting because the Governing Council has signaled a data-dependent, meeting-by-meeting stance without pre-committing to further tightening, and recent communications emphasize evaluating transmission effects after the latest adjustment. Incoming data on euro-area inflation, growth resilience, and energy prices will shape the next steps, with December seen as the more likely window for any additional move. A sharper-than-expected inflation uptick or renewed geopolitical escalation could still prompt an October shift, though current pricing reflects limited near-term likelihood.
