ECB’s Rehn Signals Potential Rate Hikes in Adverse Scenario to Preserve Credibility

European Central Bank (ECB) Governing Council member Olli Rehn stated on Tuesday that raising interest rates may become necessary in an adverse economic scenario to maintain the central bank’s credibility. The remarks, made during a speech in Helsinki, underscore the delicate balancing act facing policymakers as they navigate persistent inflation risks against a backdrop of slowing growth.

Context and Rationale

Rehn, who also serves as the Governor of the Bank of Finland, emphasized that the ECB’s primary mandate remains price stability. While the current baseline projection does not foresee immediate rate increases, Rehn cautioned that a deterioration in economic conditions—such as a renewed supply shock or wage-price spiral—could force the Governing Council to act. “In an adverse scenario, we must be prepared to raise rates further to ensure that inflation expectations remain firmly anchored,” he said.

The comments come as the eurozone grapples with above-target inflation, currently hovering around 2.4%, and weak economic momentum. Markets have priced in a potential rate cut in June, but Rehn’s hawkish tone suggests that the ECB is not ready to declare victory over inflation.

Market and Policy Implications

Rehn’s statement adds to a growing chorus of ECB officials warning against premature easing. The central bank raised rates aggressively in 2022-2023 to combat double-digit inflation, but has held rates steady since September 2023. The key deposit rate stands at 4.00%, a record high.

Analysts interpret Rehn’s remarks as a signal that the ECB is prioritizing credibility over short-term growth support. “The ECB is acutely aware that losing credibility on inflation would be far more costly than a mild recession,” said Carsten Brzeski, global head of macro at ING. “Rehn’s comments reinforce the view that rate cuts are not imminent, especially if data surprises to the upside.”

What the Adverse Scenario Looks Like

Rehn outlined several factors that could trigger an adverse scenario: a sharp escalation of geopolitical tensions disrupting energy supplies, a sustained rise in services inflation, or a rapid increase in wages outpacing productivity gains. Under such conditions, the ECB would need to tighten policy further, even if it means slowing economic activity.

This is not a hypothetical risk. The eurozone narrowly avoided a recession in the second half of 2023, and the recovery remains fragile. Germany, the bloc’s largest economy, is still contracting. A new rate hike cycle could deepen the downturn, but Rehn argued that the alternative—unchecked inflation—would be worse.

Conclusion

Rehn’s warning serves as a reminder that the ECB’s fight against inflation is not over. While markets are focused on the timing of the first rate cut, policymakers are preparing for the possibility of further tightening. For investors and businesses, the key takeaway is that the ECB will not hesitate to raise rates if price pressures re-emerge, even at the cost of slower growth. The central bank’s credibility, Rehn stressed, is non-negotiable.
