• Banque de France Governor Emmanuel Moulin warns that the Middle East energy shock is spilling into global financial markets, pushing up borrowing costs even for fiscally strong nations.
  • He suggests rising long-term bond yields may already be tightening conditions enough to warrant a more moderate ECB response, though a December hike remains possible.
  • The ECB held rates steady last week after two increases this year, but policymakers discussed further action if inflation fails to improve.

Spillovers Beyond Borders

Rising long-term government bond yields are transmitting the energy shock across borders, threatening to tighten financing conditions globally, Bank of France Governor Emmanuel Moulin said, warning that the impact is not confined to countries directly involved in the conflict. Speaking at a conference in Paris earlier this month, Moulin—who also sits on the European Central Bank’s Governing Council—highlighted the correlation between oil prices, US Treasury yields, and European interest rates. His remarks, first reported by Bloomberg, underscore growing concerns that higher oil prices are feeding inflation expectations and lifting borrowing costs worldwide.

“What we are seeing is a shock that started in energy markets but is now spreading to financial markets,” Moulin said, according to people familiar with the matter. “Even countries with strong public finances are not immune to higher global rates.”

ECB’s Measured Approach

The warning came ahead of the ECB’s October 29-30 meeting, where policymakers left rates unchanged after increases in June and September. Moulin, who has advocated a data-dependent, meeting-by-meeting approach, argued that higher market yields were already “doing the job” of restraining demand, potentially reducing the need for further policy tightening. He stopped short of endorsing market expectations of three additional rate hikes, according to two officials who spoke on condition of anonymity.

Still, the central bank discussed another increase and could act in December if the inflation outlook fails to improve, Bloomberg reported, citing people familiar with the deliberations. An ECB spokesperson declined to comment on internal discussions. The central bank has faced pressure to balance fighting imported inflation against the risk of unnecessarily weakening growth.

Fiscal Pressures Beyond the ECB’s Reach

While the ECB sets short-term policy rates, long-term yields are driven by markets—and those yields have risen sharply since the summer as energy prices climbed. For France, the challenge is compounded by domestic political uncertainty and a deteriorating fiscal position. Moulin has argued that France’s budget problems require a national solution rather than reliance on the ECB. He noted that higher rates are adding almost €10 billion annually to France’s interest costs, according to remarks made in October.

“Monetary policy cannot substitute for fiscal responsibility,” he said at the time, adding that France’s borrowing premium partly reflects its political and fiscal situation. The IMF’s latest outlook projects global growth of 3.1% in 2026 and 3.4% in 2027, with headline inflation at 4.7% and 4.1% respectively, though it warns of renewed inflation pressure and divergent growth.

The central policy debate now hinges on whether the energy shock proves short-lived or becomes embedded in broader prices and wages. Moulin has advocated looking through a temporary spike but stands ready to support a stronger response if inflation expectations become unanchored. For now, his message is clear: the fallout from the energy shock extends far beyond the region, and no economy is fully insulated.
