Bundesbank's Nagel Says Iran Conflict Could Force ECB to Raise Rates

Persistent high energy prices linked to Middle East tensions increase the likelihood of further tightening unless inflation shifts materially

By Marcus Reed

Bundesbank President Joachim Nagel warned that the conflict in Iran and elevated energy costs could prompt the European Central Bank to raise interest rates. Nagel said rate hikes are becoming more likely if the inflation outlook does not change significantly, noting supply shocks can ripple through many categories of goods and that the euro-area economy's weakness complicates policy decisions.

Bundesbank's Nagel Says Iran Conflict Could Force ECB to Raise Rates

Key Points

  • Bundesbank President Joachim Nagel said high energy prices tied to the Iran war raise the likelihood of ECB interest-rate hikes unless the inflation outlook changes fundamentally.
  • Economists and markets expect two ECB rate moves in 2026 (June and September), with a potential third move priced in by year-end; any decision next month would coincide with updated economic forecasts.
  • Nagel warned that supply shocks from higher energy costs can take up to 18 months to affect all goods categories, increasing the risk of broader inflation pressure - a concern for sectors sensitive to energy and input costs, including transport and manufacturing.

Overview

Bundesbank President Joachim Nagel said the European Central Bank may need to lift interest rates in response to the Iran war and its effect on energy prices. Speaking to Handelsblatt, Nagel stressed that while he hopes for a de-escalation in the Middle East, high energy costs cannot be ignored and may push the ECB toward additional tightening.

Timing and market expectations

Nagel pointed to market and economist expectations that envisage two policy moves in 2026 - in June and September - with traders pricing in a possible third increase by the end of the year. He also noted that any action at the next ECB meeting would arrive alongside fresh economic projections, emphasizing the role of updated forecasts in the decision-making process.

Shift in projection scenarios

Referencing the ECB's March projections, Nagel warned that the economy no longer aligns with the Eurosystem's baseline path and is instead moving toward what the institution outlined as its adverse scenario. That shift, he said, contributes to the heightened probability of further rate increases unless the inflation picture changes fundamentally.

On inflation risks

Nagel cautioned that the inflationary impact from higher energy costs may extend beyond fuel. "It’s likely that price increases won’t be limited to fuel," he said, adding that experience shows a supply shock can take up to 18 months to spread across all categories of goods. That timeframe, he suggested, could lengthen the period of inflationary pressure.

Balancing growth and price stability

While acknowledging that a fragile euro-area economy complicates the choice to raise rates - "Nobody likes to raise rates when growth is under intense pressure" - Nagel reiterated the primacy of the ECB's remit. "But our mandate is price stability. And in the long run, it’s better for everyone if it’s clear that we take our inflation target seriously and keep the inflation rate close to 2% over the medium term. We will do our job - no ifs, ands, or buts."

Implications

Nagel is regarded as one of the more hawkish members of the ECB's Governing Council. His comments frame the Iran war and its influence on energy prices as potential catalysts for policy tightening, albeit conditioned on how inflation and growth evolve ahead of upcoming meetings.

Risks

  • Persistently high energy prices could keep inflation elevated, complicating the ECB's path to its 2% medium-term target - impacting consumer goods and energy-intensive industries.
  • Inflationary pressure may spread beyond fuel to other categories over time, potentially increasing cost pressures for supply chains and logistics operators.
  • A weak euro-area economy could make policymakers hesitant to tighten policy, creating uncertainty for bond markets and businesses reliant on stable financing conditions.
