Rising US interest rates and a surge in artificial intelligence (AI) spending by major tech companies have caused significant disruptions in financial markets. In just nine months since January 2024, tech sector borrowing has reached approximately $500 billion, with Goldman Sachs predicting this figure will rise to $1.2 trillion by 2027. This borrowing binge is straining the market for US Treasury bonds and driving up interest rates, affecting everything from mortgages to car loans.

Story summary
The tech sector has seen a significant increase in borrowing since January 2024, with companies like Google, Meta, Amazon, and Microsoft raising debt to fund AI infrastructure. In just nine months, the total amount borrowed reached around US$500 billion (S$639.7 billion), compared to almost nothing in the previous year. This borrowing spree is causing ripples in the financial market, including an impact on US Treasury bonds. Goldman Sachs predicts that by 2027, this figure could rise to US$1.2 trillion, making AI sector borrowing exceed historical benchmarks for infrastructure development. Chris Della Fave from Post Oak Group estimates that currently, AI accounts for about 25% of all corporate bond issuance, up from just 4% two years ago. This trend is unprecedented and could have significant implications on global financial stability and market dynamics.
