From "Good Place" to High Alert

As recently as December 2025, the ECB projected headline inflation at just 1.9% for 2026, a mild undershoot of its 2% target. President Christine Lagarde described the eurozone economy as being "in a good place." By January 2026, annual inflation had actually fallen to 1.7%, driven by easing energy costs and softer goods prices. Rate hikes were not on anyone's agenda.

That picture changed sharply with the outbreak of conflict in the Middle East and its rapid impact on global energy markets. Oil and gas prices surged, supply route risks intensified, and the ECB was forced to revisit its entire projection framework heading into March.

The March Decision: Hold, but Vigilant

The Governing Council's decision to keep rates unchanged on March 19 was widely expected. What caught markets off guard was the tone. The official ECB statement read directly: "The war in the Middle East has made the outlook significantly more uncertain, creating upside risks for inflation and downside risks for economic growth."

Lagarde retired her "good place" framing entirely. At the press conference she stressed that the ECB is "particularly alert to so-called second-round effects, where an initial energy shock spreads beyond fuel costs into wages, services and core inflation.

The institution's formal stance remains data-dependent and meeting-by-meeting. But the shift in language, from reassurance to explicit vigilance, carries a clear signal.

What the Projections Show

The March 2026 Eurosystem staff projections document the scale of the revision. Headline inflation is now forecast at 2.6% in 2026, 2.0% in 2027, and 2.1% in 2028. Core inflation, excluding energy and food, is projected at 2.3% in 2026. These numbers are revised upward from December, especially for 2026, because energy prices will be higher owing to the war in the Middle East.

On growth, the picture is weaker. GDP is now projected at just 0.9% in 2026, down from 1.2% three months ago, with only a gradual recovery to 1.3% in 2027 and 1.4% in 2028. The downward revision reflects the drag on commodity markets, real incomes, and business confidence from the ongoing conflict.

Most striking is what the alternative scenarios show. Under a severe energy shock, headline inflation could reach 4.4% in 2026, remaining 2.8 percentage points above the baseline through 2027. These tail-risk figures are explicitly driving the hawkish turn in Governing Council rhetoric.

Voices on the Council

Governing Council member Peter Kazimir stated that the Iran war and its impact on inflation risk forcing the ECB to raise rates sooner than anticipated. Fellow member Madis Muller acknowledged that the chances of a rate hike have risen but urged against hasty action given the uncertainty around the conflict's duration and scale.

The Governing Council is not unified. Hawks point to the 2022 Russia-Ukraine precedent, when delayed ECB action allowed energy-driven inflation to embed itself into wages and services, requiring an aggressive catch-up cycle. Doves argue that the same energy shock suppressing purchasing power may do part of the ECB's disinflationary work without any intervention.

Market Repricing

The shift in market positioning has been decisive. ECB-dated OIS now prices approximately 40 basis points of hikes through year-end 2026, having previously maintained a modest easing bias. Expectations for rate cuts have been abandoned entirely. Forward curves fully discount a first hike by September, though trader conviction about a second move remains limited, reflecting skepticism about the ECB's willingness to tighten into a weakening economy.

The Core Risk: Second-Round Effects

The ECB's deepest concern is not the energy price spike itself but whether it embeds into wage demands and service prices, replicating the inflationary spiral of 2021 to 2022. The ECB's adverse scenario models explicitly incorporate stronger indirect and second-round effects than standard estimates, accounting for non-linearities observed during the last energy crisis.

For now, long-term inflation expectations remain anchored and negotiated wage growth indicators point to further easing in labour costs through 2026. But this reassurance is conditional. If energy prices stay elevated long enough for firms and workers to revise their pricing and wage-setting behaviour, the ECB's window to act pre-emptively narrows fast.

Conclusion

The ECB enters the second quarter of 2026 in a position it had not anticipated three months ago: above-target inflation, weakening growth, and an active geopolitical shock creating non-linear upside risk to prices. The March meeting marks a clear turning point in tone. Whether that turn translates into action at April or June will depend on how energy markets and second-round indicators evolve over the next six weeks. What is no longer in doubt is that the rate-cut cycle that defined 2025 is over.

Frequently Asked Questions

  1. Why did the ECB hold rates in March 2026? The ECB held at 2.0% as the medium-term impact of the energy shock remains uncertain and core inflation expectations are still anchored.
  2. What is driving the upward inflation revision? Higher energy prices from the Middle East conflict pushed the 2026 forecast from 1.9% to 2.6%, with some indirect pass-through into goods and services.
  3. What are second-round effects? They occur when an energy shock triggers wage demands and broader price rises across the economy, creating a self-sustaining inflation cycle as seen in 2021 to 2022.
  4. When is the next ECB meeting and could rates rise? The April 29 to 30 meeting is live, with markets pricing roughly 50% probability of a hike. June is considered the more likely timing for a first move.
  5. What does the severe scenario mean for the eurozone? ECB modelling shows inflation could hit 4.4% in 2026 if energy disruption persists and second-round effects intensify, remaining well above target through 2027.
