The guns may have gone quiet, but the energy bill hasn’t. European Central Bank officials are warning that the mid-June ceasefire between the US and Iran, while welcome, won’t be enough to unwind the inflationary damage already baked into the eurozone economy.

ECB President Christine Lagarde and her colleagues have made clear that elevated energy costs, supply chain disruptions, and restocking challenges will keep inflation sticky for months. The central bank backed up that assessment with action: a 25 basis point hike to the deposit rate, bringing it to 2.25%. It’s the first rate increase since 2023.

Peace on paper, pain at the pump

The US-Iran ceasefire, announced around June 15, did produce the expected reaction in oil markets. Prices fell on the news. But a ceasefire doesn’t magically refill depleted inventories or unsnarl supply chains that have been under stress for months.

The Strait of Hormuz, one of the world’s most critical chokepoints for energy shipments, was at the center of escalating tensions throughout the conflict. Even with hostilities paused, ECB officials have flagged that normalization of energy flows through the strait could take considerable time.
