French bond market instability may be contributing to a temporary easing of borrowing costs in the United States. As investors divested from French government bonds due to growing fiscal and political uncertainties, they redirected funds toward perceived safe-haven assets like US Treasurys and German bunds, according to Vishnu Varathan, head of macro strategy for Asia Pacific at Mizuho.
“The initial reaction seems to reflect a flight to safety (favoring Bunds and USTs) rather than broad-based contagion,” Varathan noted in a report released on Thursday.
This shift hasn’t caused Treasury yields to decline. In fact, they rose slightly overnight, but the increased appetite for secure investments is helping cap those gains, he explained.
On Thursday morning, the 10-year US Treasury yield hovered around 5.3%, while France’s 10-year OAT yield stood at 4.9%. Both yields approached levels not seen since 2002.
France has emerged as the latest focal point of a worldwide bond sell-off driven by persistent inflation, rising energy prices, and expanding debt levels, as market participants voice growing concerns over the nation’s fiscal outlook.
The surge in artificial intelligence investment is intensifying these pressures, with investors anticipating that productivity improvements will fuel economic expansion and sustain elevated interest rates for an extended period.
Large-scale corporate financing to support data centers and other AI-related infrastructure is also vying with government bonds for investor capital, contributing to upward pressure on yields.
Despite these overarching challenges, France’s bond market distress has not yet sparked widespread financial contagion that would compel the European Central Bank to take immediate action, Varathan observed.

Should market conditions deteriorate further, the ECB might opt to decelerate its bond repurchase program unwind to stabilize markets.
Varathan also anticipates that government borrowing expenses will remain high as investors seek higher returns to offset the risks associated with long-term debt holdings.
For US Treasurys, this temporary relief may prove short-lived given America’s own fiscal vulnerabilities and geopolitical uncertainties, leaving it susceptible to comparable market scrutiny.
“Bond vigilantes will simply choose when and how to launch their campaigns,” Varathan concluded.
