Euro zone inflation climbed back above 3% in August, driven by surging energy costs tied to the ongoing Iran war and Strait of Hormuz disruption.
Headline inflation in the euro area rose to 3.3% in August, up from 2.9% in July, marking the highest level since September 2024.
The data came from a flash estimate published by Eurostat, the European Union’s official statistics office, on Tuesday.
Energy inflation was a primary driver, accelerating sharply to 14.3% in August from 10.3% the previous month.
The euro zone, as a net importer of energy, has been hit particularly hard by the Iran conflict’s ripple effects on crude oil, refined products, and natural gas markets.
Core inflation, which strips out volatile components including energy, food, alcohol, and tobacco, actually dipped slightly to 2.4% from 2.5%.
Markets moved quickly to price in a response from the European Central Bank, with LSEG data showing a 98.9% probability of a 25 basis point rate hike at the ECB’s September 10 meeting.
Such a move would bring the ECB’s key rate to 2.5%, following the central bank’s June hike to 2.25%, which was its first increase since 2023.
The ECB raised borrowing costs in June in direct response to global inflationary pressures stemming from the Iran conflict, and policymakers now face renewed pressure to act again.
Joe Nellis, head of economic research at MHA, warned that the central bank must remain alert to the risk that short-term inflation pressures become structural, feeding into wages and services prices.
“The ECB faces a dilemma: a trade-off between higher interest rates and economic cost,” Nellis said in emailed comments. “Higher borrowing costs will continue to squeeze heavily indebted households, weaken housing markets and make investment more expensive for businesses.”
Nellis also flagged particular concern for smaller enterprises already operating under financial strain across the region.
“For SMEs in particular, another increase in financing costs could mean investment plans being indefinitely postponed or abandoned altogether,” he said.
The back-to-back inflation prints of 2.8% in June and 2.9% in July had already signaled a building trend before August’s sharper acceleration confirmed it.
Businesses and households across the euro zone now face the compounding pressure of elevated energy bills and the prospect of tighter credit conditions heading into the autumn.
