- The ECB had reached its 2 percent inflation target before the Iran war began in February. Energy prices are now pushing short-term inflation expectations higher even as the Council holds its benchmark deposit rate at 2.00 percent.
- The Governing Council adopted a meeting-by-meeting approach, explicitly refusing to pre-commit to any path — a signal that the next move could be a cut or a hike depending on how the conflict evolves.
- The Transmission Protection Instrument remains on standby to counter disorderly market dynamics in any euro area member state that might face disproportionate pressure from global volatility.
The European Central Bank kept its deposit facility rate at 2.00 percent, the main refinancing rate at 2.15 percent, and the marginal lending rate at 2.40 percent at its April 30 meeting — the first hold after a series of cuts that had brought rates down from a peak of 4 percent in 2023. The decision reflected a rapidly changed inflation context: the euro area had entered 2026 with headline inflation at approximately 2 percent, consistent with the Council’s target, but the Iran war launched in February has driven energy prices sharply higher, pushing short-term inflation expectations above that level.
The ECB statement described the situation carefully: “Inflation expectations over shorter horizons have moved up significantly” but “long-term expectations remain anchored.” The Council is essentially betting that the energy shock is a temporary disruption rather than a persistent inflationary force, while acknowledging that its durability depends entirely on a geopolitical variable — the length and intensity of the Iran conflict — that no monetary model can predict with precision.
The eurozone’s double exposure
Europe faces the Iran war’s economic consequences through two channels simultaneously. Energy costs are rising because Gulf supply disruptions and tanker rerouting via the Cape of Good Hope have pushed natural gas and oil import costs higher. Simultaneously, export demand is softening because global growth forecasts have been revised downward, American tariffs on European manufactured goods remain in force, and consumer confidence has deteriorated as energy bills rise. The combination — rising costs, falling growth — is one that monetary policy cannot address with a single instrument.
The ECB’s APP and PEPP bond portfolios continue declining as reinvestments from maturing securities stop — a passive tightening that continues in the background regardless of rate decisions. The Council has left the Transmission Protection Instrument available to deploy if sovereign spreads in any member state widen disruptively, but has not activated it. Italy’s spread over German Bunds has widened modestly since February, not dramatically.
What comes next
The ECB’s next meeting is in June, and by then the Middle East picture may have clarified. The Trump-Xi summit’s Hormuz agreement, if it translates into genuine pressure on Iran’s naval activity, would reduce energy volatility and allow the Council to resume cutting. A further escalation of tanker harassment or a Hormuz incident would do the opposite. The ECB is, in practical terms, waiting on geopolitics for permission to do monetary policy.
