French financial stability faces inflation, sovereign debt risks

The French financial system, while resilient, now confronts the fallout from the war in Iran, which began on February 28. The conflict triggered a negative supply shock in commodity markets, particularly after the closure of the Strait of Hormuz, impacting 20 percent of global hydrocarbon consumption.

Despite high inventories limiting crude oil price surges, broader price pressures are affecting various commodities, leading to upward revisions in inflation forecasts.

The Banque de France, in its June macroeconomic projections, raised its 2026 inflation forecast to 2.5 percent, an increase of 0.8 percentage points from March's interim projections.

This follows 0.9 percent inflation in 2025.

Market participants now anticipate further monetary policy tightening by the Eurosystem; as of June 12, 2026, they were pricing in one to two additional 25-basis-point rate hikes by year-end, building on the increase decided by the ECB Governing Council on June 11.

The rise in long-term interest rates across G7 countries has heightened vulnerabilities in government finances.

Expectations of further euro rate hikes have pushed up sovereign yields, with the French ten-year government bond reaching 3.75 percent on June 12, a 40-basis-point increase since the war's onset.

Despite this, the spread to the German Bund widened by only 8 basis points, reflecting persistent demand for French debt.

However, this demand must absorb growing financing needs.

Failure to reduce the budget deficit to at least 5 percent of GDP could erode support for sovereign debt, increasing downgrade risks and potentially leading to higher volatility and reduced liquidity, amplified by short-term, procyclical strategies from hedge funds active in repo markets.
