- ECB raised its key interest rate by 0.25 percentage points to 2.25% on Thursday, marking its first hike since 2023.
- ECB said the increase was needed to offset inflationary pressures generated by the U.S.-Iran war, which is pushing up energy prices that feed into food, goods and services costs.
- ECB lifted its headline inflation forecast for the euro zone to an average of 3% in 2026, then 2.3% in 2027 and 2% in 2028.
- ECB trimmed its growth outlook, now expecting average euro‑zone growth of 0.8% in 2026, 1.2% in 2027 and 1.5% in 2028.
- Lagarde reiterated that the war creates upside inflation risks and downside growth risks, and the bank is not pre‑committing to a specific rate path.
- Euro‑zone inflation rose to 3.2% in May, according to flash data, driven by higher energy costs.
- German bund yields fell by two basis points, and the euro was flat against the dollar and the pound after the announcement.
Why it matters: The hike raises borrowing costs for households and firms across the euro zone, aiming to curb inflation that has surged due to the Iran war’s energy shock, while the trimmed growth outlook signals tighter economic conditions; bond markets reacted with lower yields as investors reassess policy direction.
