French Inflation Accelerates to 2.8% in May, Highest in Over Two Years

French consumer prices rose 2.8% year-on-year in May, their highest level since February 2024, according to INSEE. The figure confirmed a preliminary reading and marks a sharp acceleration from April's 2.5% harmonized rate, raising new fears about a French economy already slipping into contraction.
The jump is driven almost entirely by energy costs, which surged 16.6% year-on-year in May, up from 14.3% in April, Reuters reported. At the same time, France's economy shrank 0.1% in the first quarter of 2026, making this a rare and uncomfortable mix of rising prices and falling growth.
The biggest culprit behind May's inflation spike is energy. Gas prices alone jumped 10.3% in a single month, INSEE confirmed in its June 12 report. That compares to just a 0.7% monthly rise in April. Energy's overall year-on-year gain of 16.6% dwarfs every other category in the basket.
Food inflation, by contrast, actually eased slightly to 1.1% from 1.2%. Core inflation — which strips out energy and food — rose to 1.5% from 1.2%. Services prices climbed to 2.1%. The data makes clear that this is an energy-led shock, not a broad overheating of the French economy.
The root cause traces back to March 2026, when conflict in the Middle East led to the effective closure of the Strait of Hormuz. That waterway carries roughly 20% of the world's petroleum. When it shut down, global oil and gas prices spiked to levels not seen since 2023, hitting French households directly at the pump and on their energy bills.
The Bank of France's new governor, Emmanuel Moulin, said earlier forecasts of 1.7% annual inflation were now "overly optimistic," Bloomberg reported. He warned that France faces a period of "less growth and higher inflation" — a toxic combination sometimes called stagflation.
The European Central Bank responded on June 11 by raising its deposit rate by 25 basis points to 2.25% — its first hike since 2023. ECB President Christine Lagarde said "the war in the Middle East is generating inflation pressures" while also noting that "labour demand has cooled further," according to Yahoo Finance.
The timing is difficult. France's GDP shrank 0.1% in Q1 2026, revised down from an earlier flat reading. Analysts at Aberdeen Investments noted the ECB described itself as "well-positioned," hinting that this may be a one-off hike rather than the start of a sustained tightening cycle, MarketScreener reported.
French Economy Minister Roland Lescure urged "vigilance without alarmism." He told BFM TV that French inflation remains "contained, notably compared with our European neighbors" — pointing out that Spain is running at 3.6% and Italy at 3.3%, according to Xinhua. Household confidence has fallen to 82 points, a three-year low.
The far-right National Rally saw a political opening. Party leader Jordan Bardella accused the government of "inaction" over the energy crisis. Marine Le Pen called for slashing VAT on energy from 20% to 5.5%, calling it a "good of primary necessity." With France's 2027 presidential race already in view, purchasing power is now a front-line political issue.
