Global Bond Selloff Deepens as Inflation Fears and Deficit Spending Drive Yields to Multi-Year Highs

The Quick Take

• Japan's 10-year yield hit 3%, its highest level since 1996, as global bond markets sold off amid inflation and deficit concerns.
• Rising government debt and war-related deficit spending are compounding upward pressure on interest rates worldwide.
• Higher borrowing costs are tightening financial conditions for both public sector issuers and corporate borrowers globally.

Global bond markets are in the grip of a broad selloff, with Japan's 10-year yield reaching 3%—its highest since 1996—as investors reassess the trajectory of government debt and inflation across major economies. Structural forces including elevated deficit spending tied to defense programs, energy-transition costs, and legacy pandemic obligations are pushing sovereign borrowing requirements higher in parallel. This dynamic is compressing the bond market's traditional safe-haven role and challenging the standard inverse correlation between equities and fixed income.

Rising yields across the US, Europe, and Japan tighten financial conditions globally, increasing the cost of capital for corporate borrowers and reducing the present-value appeal of growth equities. Sectors most exposed to rate sensitivity—real estate investment trusts, utilities, and high-growth technology—face the steepest multiple compression. Simultaneously, banks with long-duration bond portfolios face mark-to-market losses, while floating-rate lenders benefit. Governments facing near-term debt refinancing must roll at higher rates, squeezing fiscal space in economies already running structural deficits.

Monitor upcoming central bank decisions from the Bank of Japan, Federal Reserve, and ECB for any signals of yield-curve control adjustments or rate guidance changes that could arrest the selloff. The macro variable determining thesis durability is inflation trajectory: if core CPI across G7 economies fails to decline as expected through late 2026, yields have room to push higher, amplifying pressure on sovereign and corporate borrowers alike. Japan's 3% threshold is a psychological and technical resistance level that, if sustained, could trigger capital reallocation from Japanese pension funds out of JGBs into global assets.
