By David Barwick – FRANKFURT (Econostream) – The European Central Bank’s monetary policy decision on Thursday was consistent, at least at first glance, with the “one-and-watch” scenario we outlined ahead of the meeting.

The core decision was not the question, with the 25bp hike essentially a foregone conclusion. More relevant was whether the Governing Council would make the move appear to be the first step toward a broader tightening sequence after June.

On the basis of the decision statement alone, it did not. The ECB said the hike was “robust across a range of scenarios” for how the Middle East shock could affect the Eurozone, a somewhat defensive-sounding formulation that we suspect was designed to preempt the charge that a move would be vulnerable to quick exposure as a mistake.

The ECB also said that the outlook remained uncertain, “with upside risks for inflation and downside risks for economic growth.”

“This uncertainty is also reflected in the broad range of outcomes for inflation and growth in the updated illustrative scenarios,” the ECB said, a comment that further underscores the difficulty of setting monetary policy in advance and would support our expectation that President Christine Lagarde will tread carefully at the press conference.

Unsurprisingly, the ECB retained its meeting-by-meeting, data-dependent approach and said explicitly that it was “not pre-committing to a particular rate path.”

The updated projections supported the move but underscored how unsettled the question is of which of the countervailing forces will prevail; inflation was revised up for 2026 and 2027 and core inflation remained above target in 2028. At the same time, growth was revised down for 2026 and 2027, reflecting the war’s impact on commodity markets, real incomes and confidence.

That combination is broadly in line with the pre-meeting picture, neither counterindicating today's move nor by itself amounting to any roadmap for further tightening.

While noting that the conflict’s implications would depend on the possible scale of indirect and second-round effects, the statement did not claim that such effects had already become entrenched.

The fuller signal will come from Lagarde’s press conference. Based on the statement alone, the ECB has moved from vigilance to action, but not from optionality to a post-June path.
