An ECB rate hike is ‘all but certain’ — but investors divided on what comes next

Christine Lagarde, president of the European Central Bank (ECB), during a rates decision news conference in Frankfurt, Germany, on June 11, 2026. Markets are pricing in a 100% chance of the ECB raising its key interest rate by at least 25 basis points, according to LSEG data. ECB officials have emphasized a meeting-by-meeting approach to monetary policy.

Inflation in the euro zone hit 3.3% in August, with energy inflation surging to 14.3%, driven by geopolitical tensions in the Middle East disrupting commodity transit through the Strait of Hormuz, causing oil prices to spike and remain volatile. Government borrowing costs have risen sharply, with European bond yields hitting multi-decade highs. The ECB raised rates in June for the first time since 2023, bringing the key interest rate to 2.25%, making it the first major central bank to act in response to the war.

ECB President Christine Lagarde noted upside risks for inflation and downside risks for economic growth but stressed policymakers are not pre-committing to a particular rate path. Analysts, such as Felix Feather from Aberdeen, argue an ECB hike is 'all but certain,' but the real question is whether the bank’s tone signals the start of a prolonged tightening cycle. The eurozone economy has shown resilience, while high energy prices, stronger wage trackers, and elevated inflation expectations keep policymakers focused on inflation risks.

However, underlying inflation measures have eased, wage pressures remain contained, and there is little evidence of widespread second-round effects from the energy shock. Analysts also warn that the ECB could face reputational risks if it miscalculates a 'one and done' hike, leaving it behind other major central banks. Additionally, the ECB must navigate accommodating bond spreads across sovereign states while coordinating monetary policy.

Investors remain divided: a Deutsche Bank survey shows no consensus on the ECB’s rate path, with some predicting further hikes to 2.75% or even a terminal rate of 3%.
