Global bond yields and credit spreads have risen significantly due to a massive increase in debt issuance from both governments and artificial intelligence companies. Initially, credit spreads for AI-linked hyperscaler bonds widened markedly against U.S. Treasury yields. The 10-year credit spread for these providers reached approximately 121 basis points above the U.S. 10-year Treasury rate, exceeding the broader investment-grade corporate bond index. This trend reflected investor concerns regarding high financing costs for massive AI-related spending. As the situation progressed, real yields reached decade-high levels across major economies. This surge was driven by a competition for capital as AI hyperscalers, including Alphabet, Amazon, and Meta, issued nearly $220 billion in bonds, more than doubling the volume seen in 2025. This influx of corporate supply coincided with heavy government borrowing to fund deficits in the United States, France, and Britain, pushing 30-year real yields in the U.S. toward 18-year highs. ~~The AI investment boom is now impacting broader sectors, including data center expansion, industrial equipment, and infrastructure. While technology stocks have seen gains,~~ By August 2026, the ~~massive volume of new tech-related debt is putting pressure on credit spreads.

This surge in corporate debt issuance continues to contribute to higher Treasury yields; the 30-year U.S. Treasury yield reached 5.32%, its highest level since 2007. Similar surges are evident in Europe, with French borrowing costs hitting levels not seen since 2008, German yields returning to 2011 levels, and British gilts approaching 6%. Japan 5.27%, while the 10-year yield hit a 19-month high.
