Muller Says ECB Cannot Rule Out April Interest Rate Hike

Madis Muller confirmed that the European Central Bank could raise interest rates next month. On March 31, 2026, Muller's warning showed that the ECB still saw inflation risk as unfinished. Speaking from Tallinn, the Governing Council member noted that persistent volatility in energy markets makes a policy shift necessary. High prices for natural gas and crude oil, driven by the ongoing conflict in Iran, have forced Frankfurt to reconsider its previous neutral stance. Madis Muller is part of a growing faction within the bank that prioritizes price stability over short-term growth concerns.

Energy costs rose sharply across the continent this morning. Brent crude futures moved past $120 per barrel for the first time since the initial invasion. Supply chains stay vulnerable to any escalation in the Persian Gulf. Pipelines from the region have seen reduced throughput, creating a supply gap that storage facilities cannot easily fill.

Muller Signals Shift in Frankfurt Policy Stance

Policy makers previously expected to hold rates steady through the summer. Muller changed that narrative by suggesting that the ECB can no longer ignore the inflationary pressure from imported energy. Central bank officials are monitoring the war closely to determine if these price spikes are transitory or structural. Consumer price index data for March suggests that inflation in the Eurozone has already reached 5.5%. This figure exceeds the 2% target by a serious margin.

Inflationary pressures often lead to wage-price spirals if left unchecked. Frankfurt must act to prevent secondary effects from embedding themselves in the labor market. While some members of the Governing Council prefer caution, Muller argued that the cost of delay is rising every day. Investors now price in a 40% chance of a 25-basis-point hike at the next meeting.

Eurozone households are feeling the squeeze at the pump and in their heating bills. Retail sales numbers released today showed a 1.2% decline in discretionary spending. Families are reallocating funds to cover essential utilities, which reduces the capital available for the wider service economy. German industrial output also dipped by 0.8% due to high electricity costs.

Iran Conflict Disrupts Global Energy Markets

Conflict in the Middle East has removed over 2 million barrels of daily production from the global market. Ships are avoiding the Strait of Hormuz, opting for longer and more expensive routes around the Cape of Good Hope. Insurance premiums for tankers in the region have increased fivefold since January. These logistical hurdles add another layer of cost to every gallon of fuel reaching European shores. Natural gas prices at the Dutch TTF hub jumped 15% in early trading. Storage levels in the European Union are currently at 42%, which is lower than the five-year average for late March. Governments are scrambling to secure alternative supplies from Norway and North Africa. Muller emphasized that the ECB does not have the tools to increase energy production, but it can limit the resulting inflation. Beyond energy costs, the wider Israel-Iran Conflict has introduced systemic risks to global sovereign debt markets.

“Unless the war ends quickly, a rise in Eurozone interest rates looks inevitable,” the Financial Times stated in its analysis of the current geopolitical environment.

Traders at major investment banks are adjusting their portfolios to account for a more aggressive ECB. Bond yields on 10-year German Bunds rose to their highest level in three years following Muller’s remarks. Short-term debt is seeing even more dramatic movement as the market anticipates an immediate tightening cycle. Liquidity in the sovereign bond market has tightened as participants wait for clearer signals from Frankfurt.

Economic Projections for the Eurozone Recovery

Economic growth across the 20-nation bloc is currently stagnant. Projections for the second-quarter show a meager 0.1% expansion, which is barely enough to avoid a technical recession. Manufacturing sectors in France and Italy are reporting a decline in new orders as global demand softens. Only the tourism sector shows signs of resilience as the spring season begins.

Unemployment in the Eurozone holds steady at 6.5%, providing some cover for the ECB to raise rates. A strong labor market usually gives central banks more room to maneuver without causing a spike in joblessness. Muller believes the economy is strong enough to handle a modest increase in borrowing costs. Small businesses, however, are warning that higher interest payments will limit their ability to invest in new equipment.

Global trade tensions are complicating the ECB’s task. The conflict in Iran has disrupted the flow of goods between Europe and Asia, leading to delays in the delivery of critical components. Port congestion in Rotterdam and Hamburg is increasing as vessels arrive out of schedule. These supply-side shocks are largely outside the control of monetary policy.

Policy Risk for Households

The ECB dilemma reaches households through mortgages, energy bills and business credit. A rate hike can defend credibility against inflation, but it also raises borrowing costs just as conflict-driven prices squeeze disposable income. Muller's warning therefore works as a signal to markets and governments. Fiscal support can soften the shock, yet central bankers will resist any response that lets temporary energy pressure become embedded in wages and prices.
