A Supply Shock That Shows Up First in Energy

Europe's benchmark natural gas contract hit 100 euros per megawatt-hour, a threshold unseen since December 2022. On the consumer side, new tariff schedules published in Belgium in November show fixed energy contracts up by as much as 115% since March. Oil remains elevated too: Brent for December delivery traded at $104.60 a barrel in mid-October, after a 2.0% decline during the session.

The origin of this tension is identifiable. The steady rise in fuel prices since February 2026 is tied to tensions in the Middle East. This is therefore a supply shock, not a reflection of overheating demand. For a central bank, the distinction is essential: you cannot cool a shortage, you can only prevent it from contaminating the rest of the economy.

The Mechanics of Transmission

This risk of contamination follows a familiar sequence. Energy first feeds headline inflation. It then spreads to other prices, with a lag whose duration varies by sector. US data, the only detailed point of comparison in the file, illustrate this lag. Airline tickets absorbed most of the shock, with increases of more than 2% per month in July and August and 25% year-on-year. Fuel accounts for 17% to 21% of an airline's operating costs. In most other sectors, pass-through can take several months, even several quarters. The US core index, expected at 2.4% year-on-year, has remained largely unaffected.

These figures do not describe the euro area, and transposing them as-is would be improper. They do, however, supply the logic that European officials invoke: as long as companies have not passed on their costs, the absence of visible second-round effects may be nothing more than a respite.

The ECB Between Pause and Tightening

This is precisely the argument of Peter Kazimir, governor of the National Bank of Slovakia and a leading figure among advocates of restrictive monetary policy. The ECB raised rates in June and again in September, before holding them unchanged last week. To justify its pause, it cited the absence of second-round effects, moderate wage growth and the risks that rising financing costs pose to the economy.

Peter Kazimir disputes the significance of these signals. In his view, cost pressures can accumulate before companies pass them on, and "waiting for certainty is not necessarily good policy." He also warns that slower growth does not mechanically weaken price increases, since these pressures have been building for months. According to him, the question is no longer whether new measures will be needed, but how many. Markets anticipate two to three rate hikes over the coming year, and he believes they may still be underestimating the effort required.

The debate thus pits two readings of the same picture against each other. One holds that the absence of second-round effects justifies patience. The other sees in that absence a lagging indicator that proves nothing until transmission is complete.

What Demand Reveals

Available activity indicators describe an economy moving without momentum. The French car market, a thermometer of household consumption, recorded 1,384,293 registrations over ten months, up 4.37% from a year earlier. The recovery remains modest: volume is still about a quarter below its 2019 level, and analyst Arnaud Aymé describes a market "in convalescence." The energy shock is mainly reshaping the composition of demand: the electric share rose from 24% to 41% in a year, against a backdrop of more expensive fuel.

On the corporate side, the signals are more mixed. In Belgium, Pieter Timmermans, managing director of the FEB, calls the country's economic situation "particularly worrying." Conversely, demand for services is holding up: tourism spending in the Balearic Islands rose 4.7% in 2025, faster than the number of visitors (+1.7%), and air traffic at Palma rose 2% in September 2026. As for Alstom, which cut its delivery target from 4,500 to 4,000 cars and whose free cash flow is negative at 1.248 billion euros, its case stems from execution errors on German contracts. It does not signal a general cyclical downturn.

The Limits of the Analysis

The file contains no official figures for inflation, GDP growth, unemployment or wages for the euro area. The effect of the energy shock on these variables can therefore only be inferred from energy prices, market expectations and scattered sectoral signals. The most precise transmission data are American. The ECB's arguments for patience, namely the absence of second-round effects and moderate wages, are cited but not quantified. Finally, the resilience of certain demand segments, such as tourism and automobiles, nuances the scenario of an abrupt slowdown.

A Trajectory Hanging on Transmission

What the facts establish is a massive and long-running supply shock, rates already raised twice and markets expecting more. They also establish a fundamental disagreement over how to read underlying inflation signals. They demonstrate neither persistently entrenched inflation nor a recession in the making. The outcome will depend on the coming months: if energy costs spread to non-energy prices, as tightening advocates fear, pressure for further rate hikes will intensify. If not, the ECB's caution will look justified in hindsight. Until then, households and businesses must cope with expensive energy and potentially costlier credit.
