The European Central Bank’s immediate problem is higher energy-driven inflation. Its longer-term concern is whether that shock changes wage demands, companies’ pricing decisions and inflation expectations. Officials see a risk that inflation could become more persistent, but the evidence so far does not establish a wage–price spiral.

Why wages are the decisive test
Energy costs can push up headline inflation directly. The ECB describes second-round effects as a separate step: the initial shock feeds into wages, firms’ prices or margins, and inflation expectations, making price increases broader and harder to reverse.
18 In August, euro-area inflation rose to 3.3%, driven almost entirely by higher energy costs, while underlying price pressures remained modest.

Governing Council member Olli Rehn said wage growth was moderate and that second-round effects had been absent so far. Chief Economist Philip Lane has likewise noted that workers recognize the rise in living costs, but employers face constraints on granting compensating pay increases. That helps explain the muted wage response; it does not rule out one later.

Why gas supplies still worry the ECB
Lane says a second wave of increases in both oil and gas prices means the energy shock is likely to last longer than the ECB expected in March. He expects inflation to remain higher for longer before moving back toward the ECB’s target from mid-2027.
17 Gas storage levels well below historical norms add to the risk: efforts to replenish supplies have helped push up gas prices, with potential consequences for household heating and business electricity costs.

A longer shock gives higher energy costs more time to work through the economy. It is not, by itself, proof that wages or other prices will accelerate.

What would justify another rate hike?
The ECB raised its key rates by 25 basis points in September, after a similar increase in June; the September move took the deposit facility rate to 2.50%. Its projections put average inflation at 3.0% in 2026, 2.5% in 2027 and 2.1% in 2028.

Investors have increased their bets on further hikes as energy prices have risen. Vice President Boris Vujčić cautioned, however, that market pricing is being driven mainly by energy and that the ECB will assess a wider set of economic indicators rather than treat those bets as a policy instruction.

Growth strengthens the case for considering another move, not automatically making one. Euro-area GDP surprised on the upside in the second quarter, prompting the ECB to revise up its growth outlook; a September business survey also showed an unexpected acceleration in activity. Stronger activity may give policymakers more room to contain inflation, but the critical question remains whether energy costs are spreading into sustained wage and broader price increases. The provided evidence does not establish a separate effect from global growth data on the ECB’s next decision.
