Massive AI and cloud infrastructure spending by tech giants is flooding the market with new debt. For the first time since the 2008 crisis, this oversupply, not macroeconomic fears, is becoming a primary driver of market volatility and repricing risk for existing corporate bonds.
The deleveraging that followed the 2008 financial crisis—simpler bank balance sheets, more corporate cash, and tighter lending—created a multi-year environment where corporate bond supply was constrained. This scarcity insulated markets from supply-driven volatility, a condition that is only now ending.
Tech giants are issuing massive amounts of highly-rated debt at a discount to fund AI expansion. This makes existing, lower-rated corporate bonds from other sectors look less attractive by comparison, forcing a repricing of risk and higher borrowing costs across the credit spectrum.
