• ECB policymakers are likely to raise rates in September to counter inflation risks from higher energy costs linked to Iran-war disruptions.
  • There is little appetite to signal further tightening beyond that move, with market expectations shifting toward more hikes in 2026.
  • The energy shock is complicating the ECB's inflation and growth forecasts for the eurozone.

A Rate Hike on the Horizon

According to people familiar with the matter, ECB policymakers are preparing to raise interest rates at their September meeting, a move aimed at stemming the inflationary side effects of the ongoing Iran conflict. The war has driven oil prices up sharply, feeding into higher energy costs across the euro area and pressuring the central bank to act decisively.

"The energy shock is real and persistent," one source said, speaking on condition of anonymity. "We need to respond to prevent it from becoming embedded in inflation expectations."

Limited Appetite for Further Moves

However, sources indicate that there is little appetite among policymakers to signal additional tightening beyond September. "The September hike is almost a done deal, but we are wary of committing to a longer path," another official noted. This cautious stance reflects uncertainty over the conflict's duration and its impact on growth.

Market expectations have already shifted, with investors pricing in possible further moves in 2026 as energy-driven inflation remains elevated. The European Central Bank's own forecasts are being revised to account for the higher energy prices, complicating the outlook for both inflation and economic growth in the bloc.

Balancing Act for the ECB

The ECB finds itself in a delicate position. While it must address inflation, it also risks slowing an already fragile economy. "We are walking a tightrope," a third source said. "The inflation numbers are worrying, but we can't ignore the growth risks."

The central bank has been in contact with market participants and officials, though no formal announcements have been made. The situation remains fluid, with the conflict's evolution a key variable.

As one observer put it, "September is set, but beyond that, it's anyone's guess." The ECB's next move will be closely watched, not just for its immediate impact, but for signals about the future path of monetary policy in a volatile geopolitical environment.
