On June 11, the European Central Bank raised its key interest rates by 25 basis points, sending a clear signal: in its view, the risk of inflation getting out of control outweighs the risk of a more pronounced slowdown in euro area economic activity.
This decision comes at a time when growth is already slowing, credit conditions are tightening and long-term interest rates remain high, although they are justifiable in light of economic fundamentals. Moreover, the recent rise in inflation in an economy where domestic demand is not overheating stems primarily from an imported energy shock, linked in particular to the war in Iran and supply disruptions.
Preventing price contagion
The ECB’s decision is not without justification. Headline inflation rose slightly above 3% in May 2026, driven by higher energy prices. The institution’s objective remains both legitimate and unchanged: to prevent an external shock from spreading across the entire range of prices, unanchoring inflation expectations and triggering a wage-price spiral.
The rate increase in Europe is obviously not intended to bring down the global price of oil, but rather to prevent higher energy costs from having a lasting impact on the prices of other goods and services. This is all the more relevant given that the output gap—the difference between actual and potential growth—was recently close to zero, suggesting that the slowdown was not yet particularly alarming.
However, euro area GDP contracted by 0.2% in the first quarter of 2026, following an already sluggish end to 2025. The Purchasing Managers’ Index (PMI), a useful leading indicator of economic activity, stood slightly above 48 in May, its lowest level in eighteen months. Credit surveys point in the same direction: tighter lending standards and a perceived increase in borrowing costs.
Meanwhile, underlying inflation, excluding energy and food, remains relatively contained, at around 2.2%–2.5%. So far, there has been no generalized wage-price indexation process. Brent crude prices, having peaked in early spring, have since declined, suggesting that the energy shock is beginning to ease. The agreement that appears to have been reached between the United States and Iran over the weekend further reinforced this trend at the beginning of the week.
If the Strait of Hormuz reopens on a lasting basis, upward pressure on certain prices should gradually subside.
This does not mean that the ECB is clearly making a mistake, or that there is no risk of inflation getting out of control. We must, of course, hope that its assessment of the resilience of euro area economic activity proves correct.
If the slowdown remains contained and inflation normalizes without spreading more persistently throughout the economy, this 25-basis-point increase will, in retrospect, be seen as a credible signal of vigilance.
If, on the contrary, economic activity deteriorates further, the ECB could find itself in a situation reminiscent of unfortunate precedents: July 2008, followed by April and July 2011, when rate increases prompted by global energy shocks had to be reversed relatively quickly as economic conditions deteriorated.
The decisive dividing line between stagnation and a genuine recovery
Whatever happens, the key issue lies elsewhere. In a Europe suffering from sluggish growth, long-term prosperity depends far less on a 25-basis-point change in short-term interest rates—whether upwards or downwards—than on the ability to raise potential growth sustainably.
Labour-market reforms, pension-system reforms in certain countries, competition regulation, and stronger incentives for investment, innovation and the expansion of productive capacity: these are the areas in which the decisive dividing line between stagnation and a genuine economic recovery will be drawn. Such a recovery is essential to the long-term sustainability of the European social model.
