Global bond selloff deepens as US launches fresh attacks on Iran

The United States carried out new airstrikes against Iranian targets, prompting a sharp reaction in global financial markets: oil prices climbed, equity indices slipped and bond yields surged. In particular, Japan’s benchmark 10‑year government bond yield rose to 3 percent, a level not seen since 1996, underscoring the breadth of the sell‑off across major economies.

The market turbulence is being amplified by broader concerns over inflation and sovereign debt burdens. U.S. government debt has now exceeded $40 trillion, fueling worries that fiscal pressures could force higher interest rates, while the Eurozone’s inflation rate jumped to its highest point in three years in August, driven largely by rising energy costs. These macro‑economic strains are intersecting with the geopolitical shock of the attacks, deepening investors’ risk aversion.

The combined effect of the military action and the underlying economic anxieties is a widening bond sell‑off that could constrain borrowing costs for governments and corporations worldwide. Higher yields in Japan and elsewhere signal tighter financing conditions, while the rise in oil prices may further stoke inflationary pressures, potentially prompting central banks to consider more aggressive rate hikes. The situation sets the stage for continued volatility in both currency and debt markets as policymakers grapple with the dual challenges of geopolitical instability and mounting fiscal deficits.
