The European Central Bank’s first rate rise since 2023 was driven by a renewed deterioration in the inflation outlook, rather than by strength in the eurozone economy. At its June meeting, the ECB raised rates by 25 basis points, taking the deposit rate to 2.25%, the main refinancing rate to 2.40% and the marginal lending facility rate to 2.65%, effective from 17th June. The decision followed a series of higher inflation readings linked to rising energy prices caused by the Iran conflict.
The central issue for the ECB is that the energy shock risks becoming more persistent. Higher oil and gas prices feed directly into headline inflation, but they can also affect food, goods and services prices through higher transport, production and input costs. Euro area inflation rose to 3.2% in May, up from 3.0% in April, with energy inflation running at 10.9%, compared with services inflation of 3.5% and non-energy industrial goods inflation of 0.9%. This underlines how much of the immediate inflation pressure is energy-related, although the ECB’s concern is that it does not remain confined to energy.
The Governing Council’s decision was also notable because it was unanimous. President Christine Lagarde described the move as “necessary” and a “signal”, with no alternative proposal put forward, while the ECB’s official statement said the rise was “robust across a range of scenarios” for how the shock could affect the medium-term outlook. That wording is important as it suggests the ECB was not trying to start an aggressive tightening cycle but judged that a modest pre-emptive rise was justified across several plausible inflation paths.
This explains why the ECB chose to act despite a weaker growth backdrop. Its updated projections show inflation has been revised higher for 2026/27, reflecting a higher expected path for energy prices. Headline inflation is now forecast at 3.0% in 2026 and 2.3% in 2027, before returning to the 2% target later in 2027 and into 2028. Core inflation has also been revised up, with the ECB expecting it to remain at 2.5% in both 2026 and 2027 before easing to 2.2% in 2028. Staff explicitly attributed the upward revisions to a higher path for energy prices, which is expected to feed into food, goods and services inflation.
The growth backdrop makes the decision more finely balanced. Eurostat’s revised data show euro area GDP contracted by 0.2% in Q1 2026, after growth of 0.2% in Q4 2025, while the ECB now expects GDP growth of just 0.8% in 2026 and 1.2% in 2027. However, the Q1 figure was heavily affected by Ireland, where GDP fell 12.1% because of a sharp contraction in multinational-dominated sectors; Ireland’s modified domestic demand rose by 0.6%. This means the headline euro area contraction probably overstates the weakness in underlying demand, though the overall picture remains subdued.
Market pricing has nevertheless moved to reflect the risk of further tightening, although not immediately. As at 26th June, WIRP data showed only a limited probability of a July move, with around 0.045 hikes priced for the July meeting. Pricing then rises more materially, with around 0.65 hikes priced by September, 0.75 by October and close to one full 25 basis point increase priced by December. This suggests markets expect the ECB to retain a tightening bias, but not necessarily to move at every meeting.
The impact on wider bank rates will be most direct for euro-denominated products. The ECB deposit rate anchors euro money market rates such as €STR and Euribor, so higher policy rates should feed through to government treasury bills, wholesale funding costs, floating-rate lending and Euribor-linked facilities. Euro deposit rates may also rise, particularly for corporate and institutional balances, although the extent of pass-through will depend on each bank’s liquidity position and appetite for funding.
The implications for UK banks are more indirect. Sterling lending and deposit rates remain primarily driven by Bank of England policy and SONIA expectations, not the ECB. However, UK banks with euro funding needs, euro-denominated loan books or European subsidiaries may see higher euro funding costs and repricing of euro-linked facilities. More broadly, the same energy shock is affecting other currency areas: UK CPI was 2.8% in May, with transport inflation at 6.8%, while US CPI was 4.2%, with energy prices up 23.5% and core inflation at 2.9%. The policy response will differ by central bank, but the inflation impulse is global.
Euro-denominated deposits, investments and borrowing costs are likely to be affected most clearly, while sterling products should only be influenced indirectly through broader market sentiment and any read-across to Bank of England expectations.
