When the price of a full tank of gas or a shopping cart rises week after week, the question of purchasing power quickly comes back to the table. In France, the inflation forecasts for 2026 published by INSEE paint a tighter picture than in 2025, with concrete mechanisms affecting households, businesses, and public policies.
Strait of Hormuz and tariffs: the geopolitical drivers of inflation 2026
Before looking at the raw numbers, it is essential to understand what is pushing prices up this year. Two geopolitical factors weigh heavily on the French economy, and competitors discuss them little with this level of detail.

The first is the tensions surrounding the Strait of Hormuz. This maritime passage concentrates a massive share of global oil traffic. Allianz Trade, cited by Le Monde in April 2026, presents a clear scenario: if the flows in the strait do not unblock by June, France could enter recession. This is not an abstract hypothesis. It means that the price of energy, transportation, and many imported products remains under direct pressure.
The second factor is the American tariffs. INSEE, in its economic note from March 2026, dedicates an entire section to the evolution of tariffs between the United States and Europe. These trade barriers increase the cost of exchanges and fuel the rise in prices for certain industrial and consumer goods.

Inflation in France: what INSEE measures in the first half of 2026
Have you noticed that inflation figures vary depending on the sources? This is because there are several indices. INSEE uses the consumer price index (CPI), while the European Central Bank refers to the HICP (harmonized index of consumer prices).
In March 2026, the HICP in France reached 2%, compared to an initial estimate of 1.9%. This modest upward revision reflects a trend: inflation is accelerating compared to the levels at the end of 2025.
INSEE titles its economic note from March 2026 “Revived Inflation, Fragile Growth.” The choice of words is not trivial. It confirms that the price dynamics are picking up while growth is stagnating. In the first quarter of 2026, French GDP growth was zero, according to data reported by Boursorama.
An uneven spread across sectors
BNP Paribas noted in early May 2026 that inflation is gradually spreading but still spares certain everyday consumer goods. Specifically, energy is driving prices up, while other spending categories remain relatively stable. This sectoral concentration masks the reality faced by households who allocate a significant portion of their budget to fuel or heating.
Minimum wage, purchasing power, and the price-wage loop: direct consequences for households
When inflation crosses certain thresholds, an automatic mechanism is triggered in France: the minimum wage is revalued. UNSA confirmed in April 2026 that an automatic increase in the minimum wage would occur following the observed inflation level.
This revaluation protects employees on minimum wage. It also creates tension for businesses, particularly SMEs, whose labor costs rise without necessarily seeing their revenue follow suit.
This is what economists call the price-wage loop:
- Prices rise, eroding households’ purchasing power
- Wages are revalued to compensate, increasing production costs
- Businesses pass these costs onto their selling prices, which reignites the increase
This spiral does not automatically trigger with every inflation push, but the context of 2026, with zero growth and high energy costs, creates a conducive environment.
Stagnant growth and scenarios for the second half of 2026
The French government has lowered its growth forecast for 2026 from 0.9% to 0.8%. An adjustment of 0.1 points that may seem marginal but reflects the consideration of the ongoing geopolitical shock.
François Villeroy de Galhau, Governor of the Bank of France, provided a telling range in May 2026: between 0.3% and 0.9% growth depending on the scenario. In the most favorable case, France avoids recession. In the least favorable, it brushes against it.
What shifts the scenario from one to another
Three variables determine the trajectory for the second half:
- The evolution of tensions in the Strait of Hormuz, which conditions the price of imported energy
- The final level of transatlantic tariffs, still under negotiation
- The reaction of the European Central Bank regarding its key rates, which influences credit and household consumption
If oil flows normalize and trade barriers stabilize, household consumption could gradually recover. Otherwise, the combination of high inflation and zero growth recalls a stagflation scenario.
French households’ budget: where inflation is felt daily
Beyond average indices, inflation does not affect all spending categories in the same way. Energy (fuel, gas, electricity) remains the main driver of increases in 2026. Services, on the other hand, experience a more moderate but steady progression.
For a household that spends a significant portion of its income on energy and food, the inflation felt often exceeds the average index published by INSEE. This is one of the limitations of the CPI: it measures an average basket that does not necessarily correspond to the consumption habits of every household.
The automatic increase in the minimum wage partially compensates for this loss of purchasing power for the lowest-paid employees. For the middle classes, whose salaries do not benefit from this automatic mechanism, the adjustment depends on salary negotiations within companies, which are often slower.
The year 2026 places the French economy in an uncomfortable position: rising prices, nearly zero growth, and budgetary levers constrained by public deficit. The trajectory for the second half will largely depend on external factors over which France has little direct control.
