ECB Justifies June Rate Hike as Energy Prices Fuel Euro Zone Inflation

ECB Rate Hike and Euro Zone Inflation Analysis

Energy Prices as the Primary Driver of Inflation

FRANKFURT, Sept 1 (Reuters) - The spike in euro zone inflation since the start of the war in Iran has almost entirely been driven by higher energy prices, justifying the European Central Bank's small increase in interest rates in June, new ECB research showed on Tuesday.

The ECB raised rates for the first time in nearly three years and is set to do so again next week as continued disruption to the Strait of Hormuz keeps gas and petrol prices elevated in the energy-importing euro zone.

ECB Research Findings

A new blog post by ECB researchers compared the current spell of high inflation with the one that followed Russia's full-scale invasion of Ukraine in 2022, using variables such as pandemic-related demand and supply imbalances, adverse energy supply shocks, as well as fiscal and monetary policy measures. 

Economists' Statements

"Our estimates suggest that the current increase in headline inflation has so far, until end of May 2026, been driven almost entirely by adverse energy supply shocks," economists Kristina Barauskaitė Griškevičienė and Claus Brand wrote.

Comparison with Previous Inflation Episodes

By contrast, the 2021-22 bout of high inflation was also driven by monetary stimulus at first, and fiscal stimulus later on.

Policy Response and Market Expectations

"This contrast supports the more measured policy response taken so far," the blog said. "The response as delivered to date is consistent with the medium-term orientation of the ECB’s monetary policy and with financial market expectations." 

Outlook and Expectations

Most economists expected the war in Iran to end over the course of the summer.

Key Takeaways

  • ECB researchers found that, unlike the broader Ukraine‑era inflation surge, the current inflation spike was driven nearly entirely by adverse energy supply shocks through May 2026 (ecb.europa.eu).
  • Comparative analysis shows that earlier inflation episodes also reflected strong monetary or fiscal stimulus, reinforcing the appropriateness of the ECB’s ‘measured’ policy response so far (ecb.europa.eu).
  • Ongoing Strait of Hormuz disruptions continue to fuel energy price volatility, amplifying inflationary pressures and underpinning expectations of further ECB rate increases in coming months (ecb.europa.eu).
