The European Central Bank just raised interest rates for the first time since 2023. And one of its newest policymakers is already suggesting that more hikes could be on the way.
Ulo Kaasik, who became Governor of Eesti Pank on June 7 and immediately joined the ECB’s Governing Council, said the central bank may need additional interest rate increases to keep inflation under control. His comments come days after the ECB lifted its benchmark rate by 25 basis points to 2.25% on June 11, a direct response to the inflationary pressures unleashed by the ongoing war in Iran.
The inflation picture is getting worse, not better
Eurozone inflation hit 3.2% in May, up from 3.0% in April and roughly double the sub-2% levels that prevailed before the conflict began.
The culprit is energy prices. The Iran war, which started with US and Israeli strikes on February 28, has disrupted oil supplies in a region that accounts for a significant share of global production.
Kaasik emphasized that the ECB needs to remain flexible and prepared to act if economic data warrants further tightening.
Why the ECB reversed course
The ECB spent the better part of 2024 and 2025 cutting rates, easing monetary policy as inflation appeared to be cooling toward target levels. Then the Iran conflict changed the calculus entirely. The June 11 rate hike marked the first upward move since 2023, effectively ending the easing cycle. Multiple ECB policymakers have indicated that a potential July rate hike is on the table, suggesting this wasn’t a one-and-done decision.
Kaasik is a fresh voice on the Council, having taken the Eesti Pank governorship just days before the rate decision.
What this means for investors
Rising interest rates in the eurozone have implications that extend well beyond government bond yields. Borrowing costs increase for businesses and consumers, equity valuations come under pressure, and the relative attractiveness of cash and fixed-income instruments improves.
For crypto markets, monetary tightening cycles have historically correlated with reduced appetite for risk assets. When the ECB and Federal Reserve embarked on aggressive rate-hiking campaigns in response to post-pandemic inflation and the energy shock from the Russia-Ukraine war, crypto markets suffered significant drawdowns. Bitcoin and other digital assets didn’t bottom until the tightening cycle showed signs of peaking.
The key variable to watch is whether inflation continues accelerating or stabilizes. If the 3.2% May reading proves to be a near-term peak, the ECB may pause after one or two more hikes. If energy disruptions worsen and inflation pushes toward 4% or beyond, the tightening cycle could become more aggressive.
