The European Central Bank decided on September 10 to increase all three key interest rates by 25 basis points, lifting the deposit facility rate, main refinancing operations rate, and marginal lending facility rate to 2.50%, 2.65%, and 2.90%, respectively, effective September 16. This marks the ECB's second rate hike in 2026, driven by inflationary pressures fueled by energy prices.

Energy Shock Lifts Inflation

The ECB stated that ongoing conflict in the Middle East continues to generate inflationary pressure, with euro area inflation projected to remain significantly above the 2% medium-term target for an extended period. Euro area inflation rose to 3.3% in August from 2.9% in July, with energy prices surging 14.3% year-on-year, serving as the primary driver of accelerated price growth. Core inflation, excluding energy and food, edged down slightly to 2.4% from 2.5%.

The central bank noted that wages have yet to respond significantly to the energy shock, but the longer energy costs remain elevated, the greater the risk of transmission to other goods prices, wages, and inflation expectations. The ECB staff's latest baseline projections indicate headline inflation in the euro area will average 3.0%, 2.5%, and 2.1% in 2026, 2027, and 2028, respectively. Core inflation, excluding energy and food, is projected at 2.5%, 2.6%, and 2.3% over the same period. Headline inflation is expected to return near target only by late 2027.

Economic Resilience Opens Room for Tightening

The ECB raised its 2026 euro area growth forecast to 0.9%, with expectations of 1.4% growth in 2027 and 1.5% in 2028. Both the 2026 and 2027 projections were revised upward from June, reflecting stronger-than-anticipated economic performance in the euro area. ECB President Christine Lagarde noted that second-quarter growth spanned multiple countries and sectors, with manufacturing supported by defense and infrastructure spending, while recovering consumer confidence helped services rebound from the energy shock.

The euro area unemployment rate held steady at 6.4% in July. Meanwhile, higher rates are gradually transmitting to financing markets. The average interest rate on corporate bank loans rose to 3.8% in June and July, up from 3.6% in May, while mortgage rates remained unchanged at 3.5% over the same period.

No Pre-Set Path for Future Rate Moves

This rate hike received unanimous support from the ECB's Governing Council. Lagarde stated that the decision was clearly necessary, but the Governing Council did not discuss any pre-set trajectory for future rate moves. The ECB will continue to decide on a meeting-by-meeting basis, guided primarily by the inflation outlook and associated risks, underlying inflation dynamics, and the strength of monetary policy transmission.

The central bank also cautioned that further disruptions to energy supply, low natural gas inventories, or unusually cold winter weather could keep inflation elevated for longer. Conversely, energy shocks and tighter global financial conditions could weigh on economic growth.
