Asian AI Stocks Slide as Rising Financing Costs Rattle Spending Boom

Asian stocks tied to artificial intelligence infrastructure fell in the October 17 session after a Bloomberg report flagged rising financing costs as a threat to the industry's spending boom. The AI buildout across chipmakers, data-center operators and power suppliers has leaned heavily on debt and capital markets to fund expansion, and higher borrowing costs cut into the economics of projects that assume years of heavy upfront investment before returns arrive. The move adds to a broader debate about whether AI capital expenditure plans, many of which stretch into the early 2030s, can be financed on the terms investors have assumed. It also lands the same week TSMC's results drew commentary that the AI boom is bigger and longer-lasting than expected, a split in market view that underscores how unsettled sentiment on AI financing has become. What remains unresolved is whether this is a one-session reaction to financing cost headlines or the start of a repricing of AI-linked credit risk more broadly.
