Energy Is Up 12.4% and Real Wages Are Falling. La Rentrée Is When French Households Feel the Iran War

The French economy has spent six months absorbing a war 5,000 kilometres away. In August, households start paying for it in the same month the school bills land.

INSEE's provisional estimate put consumer price inflation at 2.1% year-on-year in July, up from 1.8% in June, driven by accelerating service prices — particularly accommodation and communications — and by energy, pulled higher by gas and petroleum products. The harmonised index used for European comparison ran hotter still at 2.4%, against 2.0% in June. Month-on-month, prices rose 0.6% after a 0.3% fall in June, a rebound INSEE attributes to seasonal increases in transport and accommodation.

The headline understates what households actually experience. Energy prices are up 12.4% over twelve months. Fresh produce rose 3.8% year-on-year in July, accelerating from 2.7% the previous month, even as overall food inflation held at 0.9%.

For context on how sharp the turn has been: French inflation averaged 0.9% across the whole of 2025.

The number the government isn't leading with

The Banque de France's June central scenario expects the average wage per head to rise 2.1% in gross terms in 2026 — below its projected inflation of 2.5%. In plain terms, wage purchasing power falls this year. The central bank expects a catch-up from 2027 as energy pressure dissipates.

Households appear to have priced that in already. INSEE's consumer confidence indicator stood at 82 points in May, well below its long-run average and the lowest reading since March 2023.

Bercy's response to the July print was that the rise remains contained, consistent with June, in a context where growth reached 0.2% in the second quarter — adding that the government remains mobilised in its efforts to protect French purchasing power.

Growth of 0.2% and confidence at a three-year low are not obviously a story about containment.

Gas rose twice in five weeks

The energy line isn't an abstraction. Regulated gas prices went up 7.5% on 1 July, followed by a further 0.2% on 1 August.

France imports its energy, and the cushioning available is limited to tariff-shield mechanisms that only partially absorb the shock. A string of changes took effect on 1 August covering the Livret A rate, electricity pricing and the allocation de rentrée scolaire, with the new LEP rate published in the Journal officiel — a cluster of adjustments arriving precisely as families face back-to-school costs.

Why a Hormuz deal won't rescue la rentrée

With Washington and Tehran circling an agreement on the Strait of Hormuz, the temptation is to assume the energy premium drains and the squeeze resolves. The timing doesn't work that way.

Crude reprices in minutes. Regulated gas and electricity tariffs are set administratively and adjust on a lag. Wage negotiations run to their own calendar. And borrowing costs are moving the wrong way: mortgage rates held steady in August, but a rise from la rentrée is now considered credible.

There's also a question over how much premium is left to release. The economist Sylvain Bersinger, founder of Bersingéco, notes that INSEE's mid-June forecast of 2% average inflation for 2026 assumed a barrel at €85 — roughly where it has been trading. On that reading, absent further escalation, the trajectory stays manageable, but the relief case is smaller than the headline drama suggests.

Which leaves the awkward possibility that the market gets its good news in August and households get theirs in 2027.

The political arithmetic

This lands on a minority government. Sébastien Lecornu's administration passed the 2026 budget only by surviving two no-confidence motions, and the state deficit widened to €106.8 billion in January–June from €100.4 billion a year earlier, with spending up 5.4% against revenue up 3.7%.

Falling real wages, confidence at a three-year low, and no fiscal room to compensate — heading into a united-left primary in October and a presidential campaign in which purchasing power has decided French elections before.

Not financial advice.
