# Global bond market volatility from AI and government debt > Live situation record from CLSTR: https://clstr.news/situations/global-bond-market-volatility-from-ai-and-government-debt > Updated: 2026-08-18T06:21:54.000Z. Sources: 13. Developments: 5. 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. By August 2026, the competition for investors intensified as the U.S. national debt approached $40 trillion. Major technology companies are increasingly utilizing debt markets to finance massive investments in data centers and chips, with some estimates suggesting Big Tech borrowing now accounts for roughly 25% of Treasury net bond sales to private investors. This surge in corporate debt issuance continues to contribute to higher Treasury yields; the 30-year U.S. Treasury yield reached 5.27%, while the 10-year yield hit a 19-month high. The increased supply of corporate paper from ‘hyperscalers’ is forcing yields higher as investors demand greater returns to accommodate the influx of new borrowers. ## Claims - U.S. 30-year real yields are near 18-year highs at approximately 3%.
