Global banking official warns AI spending is built on hidden debt

The head of the Bank for International Settlements, a group that coordinates central banks worldwide, said companies are borrowing huge amounts to fund the AI buildout, but a lot of that debt isn't clearly visible or tracked. He's worried that if AI investments don't pay off, the fallout could ripple through the wider financial system.

Crypto often moves with the broader market's mood about risk, so a warning like this can rattle stocks and crypto together even though it's not about crypto directly.

Nothing to act on here. This is a big-picture warning about the traditional financial system, not a crypto-specific event, so there's no security risk or urgent decision to make.
