European stocks erased gains to trade lower as strikes on Iranian energy facilities pushed oil prices higher, reviving inflation fears and prompting traders to price two interest-rate hikes from the European Central Bank this year. The attacks on the South Pars gas field, a major energy hub, triggered immediate market reactions, with benchmark indices across Europe closing in the red. This surge in oil costs, the primary driver of inflation in Europe, forced investors to reassess central bank policies, particularly the ECB's trajectory toward tightening monetary conditions to combat rising prices.

Traders are now pricing in two rate increases from the ECB this year, reflecting heightened expectations of aggressive policy tightening. The attack on Iran's energy infrastructure disrupted supply chains, causing immediate price spikes at the pump and in energy futures markets. This development amplifies concerns about sustained inflationary pressures across the Eurozone, potentially forcing the ECB to accelerate its withdrawal of emergency liquidity measures and raise borrowing costs sooner than previously anticipated.

The market turmoil underscores the vulnerability of European economies to geopolitical shocks in key energy-producing regions. While the ECB has maintained a cautious stance, the sudden oil price surge forces policymakers to balance inflation control against economic growth risks. The immediate impact is clear: European equities are retreating, and the path for monetary policy is becoming steeper as the threat of sustained high energy costs looms large over the region's economic outlook.
