Sovereign Debt Yields Plummet as Inflation Fears Fuel Bond Selloff

A global sovereign bond selloff has reached its sixth consecutive session, driving borrowing costs to multi-year and multi-decade peaks. The market is reacting to a toxic combination of military escalation in the Middle East, corporate debt issuance for artificial intelligence, and persistent central bank hawkishness.

In the US, benchmark Treasury yields have reached fresh highs across the curve, with the 10-year yield advancing to 4.787%, its highest level since 2025. This represents an aggressive hurdle rate for capital allocation, where risk-free sovereign debt offers guaranteed 5% annual yields, making risk assets less attractive.

Europe's policy-sensitive two-year Schatz yield rose to hit 2.983%, its highest level since 2024, while long-end core yields suffered a sharper drop in price. France's 10-year OAT yield escalated to 4.244%, reaching levels not seen since the 2008 global financial crisis.

Himanshu Sahay, Arch Lending's co-Founder and chief revenue officer, said: 'When traditional borrowing costs climb like this, people holding appreciating assets start asking a simple question.' He added that it's not about timing markets, but rather not wanting to give up long-term upside just to cover a short-term cash need.

The fixed-income rout has also extended deep into the Asia-Pacific region, where Australia's benchmark 10-year government bond yield jumped to 5.205%, its highest since 2011. Japan's 10-year government bond yield hovered above 3.000%, anchoring at its highest point since 1996.

The global wave of bond selling reflects a fundamental breakdown in traditional asset dynamics, as sovereign paper is being aggressively dumped by institutional allocators due to geopolitical crises and inflation shocks.
