Key Takeaways

• Headline CPI accelerates: Eurozone annual inflation rose to 3.2% in May from 3.0% in April — in line with expectations.
• Monthly pace slows: Month-on-month CPI eased to 0.1% from 1.0% — as anticipated — offering some comfort.
• Energy the key driver: Annual energy prices surged 10.8% — matching April’s pace — driven by Hormuz closure and attacks on Gulf gas infrastructure.
• Iran deal offers relief: Oil prices have declined since the peace framework was announced; the deal’s signing on Friday could ease the energy shock.
• ECB already acted: The central bank raised rates last week, citing Iran war inflation pressures as the primary driver.
• ECB’s inflation forecasts raised: Now sees headline CPI averaging 3.0% in 2026, 2.3% in 2027, and 2.0% in 2028 — up from 2.6%, 2.0%, and 2.1%.
• Growth forecasts cut: Eurozone GDP is now seen at 0.8% this year, down from the prior 0.9% projection.
• Lagarde’s inflation target: The ECB president said inflation would return to target in autumn 2027 — but warned more persistent energy costs could push it higher.
• “Growth is absent or under threat”: Lagarde’s stark description of the current Eurozone economic environment.
• Core CPI surprises higher: The underlying annual measure rose to 2.6% from 2.2% — above the 2.5% forecast — signaling energy is seeping into the broader economy.
• Monthly core eases: The month-on-month core gauge fell to 0.3% from 0.9%, matching estimates.

Eurozone consumer price growth accelerated on an annualized basis in May, yet slowed month-on-month, as policymakers attempt to assess the impact of an energy shock induced by the Iran war.

The headline consumer price index for the 21-member currency area rose 3.2% in the 12 months to May — faster than 3.0% in April and in line with expectations — according to Eurostat data released on Wednesday.

On a monthly basis, the measure slowed as anticipated to 0.1% from 1.0%.

Energy the Dominant Force

Annualized energy prices, in particular, surged by 10.8% — equaling the rate notched in April. The closure of the Strait of Hormuz following the start of the joint U.S.-Israeli assault on Iran in late February, as well as attacks on critical natural gas production facilities in the Gulf, have led to a spike in energy costs across Europe.

Oil prices remain above pre-war levels but have declined since the announcement of a framework peace deal between the United States and Iran. The agreement — due to be signed on Friday — would reopen the Strait of Hormuz and lift an American blockade of Iranian ports, media reports said.

ECB Already Moved; Lagarde Warns on Growth

The European Central Bank raised interest rates last week, warning of the inflationary pressures being generated by the war in the Middle East.

New Eurosystem staff projections predicted that headline inflation will average 3% this year, 2.3% in 2027, and 2% in 2028 — up from prior forecasts of 2.6%, 2.0%, and 2.1%, respectively.

Eurozone growth forecasts, meanwhile, were slashed. GDP in the region is now seen at 0.8% this year, compared to prior predictions of 0.9%.

Speaking after last week’s decision, ECB President Christine Lagarde predicted that inflation would come back down to target in the autumn of 2027, although she noted that if energy costs were to rise more or for longer, price growth would increase further. She also described the current economic environment as one in which “growth is absent or under threat.”

Core Inflation Surprises to the Upside

ECB officials — like their counterparts at central banks around the world — have been watching for signs that the spike in energy prices is seeping into the broader economy.

Stripping out items like energy, food, alcohol, and tobacco, the underlying gauge of inflation came in at 2.6% year-on-year — above the 2.2% recorded in the preceding month and the 2.5% consensus forecast. The month-on-month core gauge eased to 0.3% from 0.9%, matching estimates.
