Traders bet ECB tightening will extend well beyond Thursday’s expected rate hike

The European Central Bank is widely expected to raise its deposit rate by 25 basis points to 2.50% when it announces its monetary policy decision on Thursday, September 10. The move would mark the ECB's second rate increase of 2026, after policymakers lifted the deposit rate to 2.25% in June amid mounting inflation pressure from surging energy prices tied to the US-Iran conflict.reuters+1

The decision comes after Eurostat data showed eurozone inflation accelerated to 3.3% in August, up from 2.9% in July, driven almost entirely by higher energy costs. Energy prices alone rose at an annual rate of 14.3% in August, up from 10.3% the prior month.europa+1

Markets Price In More Tightening

Financial markets have fully priced in Thursday's quarter-point increase, but traders are now positioning for a more extended tightening cycle than most economists expect. According to Bloomberg, swaps pricing suggests around 90 basis points of ECB rate increases by December 2027, implying three quarter-point hikes with a 60% chance of a fourth. That would push the deposit rate toward 3% or above — well beyond the ECB's own signaling.bloomberg

A Reuters poll published last week found that roughly 91% of economists surveyed expect the deposit rate to end 2026 at 2.50%, with most viewing Thursday's hike as the final move in what would be the ECB's shortest tightening cycle in 15 years. A Bloomberg survey reached a similar conclusion, with a majority of respondents seeing the deposit rate holding at 2.50% through 2027.bloomberg+1

Commonwealth Bank of Australia offers a middle path, forecasting one additional 25-basis-point hike in December, which would take the deposit rate to 2.75%, citing elevated energy prices persisting longer than initially expected.commbank

Energy Prices and Geopolitical Risk

The gap between economist forecasts and market pricing reflects uncertainty over the trajectory of energy costs. Brent crude has climbed back near $100 a barrel as the US-Iran conflict continues to disrupt Middle Eastern oil supply routes. ING's global head of macro, Carsten Brzeski, characterized the expected Thursday move as "another insurance rate hike" — or, as he put it, "a dovish rate hike".fxstreet+1

The ECB's decision will be followed by a press conference from President Christine Lagarde, where markets will scrutinize forward guidance for any indication of whether the September hike is the last or whether further tightening lies ahead. Signals from Frankfurt in recent weeks have pointed toward potential additional action, suggesting policymakers are already laying groundwork for their next move. With the Federal Reserve decision due the following Tuesday and the Bank of England meeting on September 17, the coming eight days represent the most concentrated stretch of central bank policy risk markets have faced this quarter.globalbankingandfinance+1
