BIS Fires the Warning Shot: AI Euphoria Has a Price

Goldman Sachs is buying Indian government bonds. China's central bank just set a rate below what anyone expected. Stocks are climbing because bargain hunters decided the weekend's tension in the Persian Gulf was survivable. And somewhere in the background, the Bank for International Settlements — the central bank of central banks, the institution that exists precisely to say what no one else will — dropped its annual report and pointed at the thing everyone in the room has been carefully not discussing.

The BIS named the AI trade.

Not gently. The report flags rich equity valuations, investor complacency, circular financing structures, and the risk of contagion into credit markets. That last part matters more than the others. When the concern is only about stock prices, it stays in the financial pages. When the concern reaches credit — when it's about the plumbing, the loans, the leverage underneath the excitement — it becomes a question about the economy itself. The BIS has watched enough cycles to know that the distance between "AI boom" and "AI correction" is not just a market problem. It's a hiring problem, a lending problem, a pension problem.

Here's the mechanism worth understanding. A significant portion of the AI investment cycle is internally self-referential: tech firms issue equity to fund AI infrastructure, AI infrastructure companies use that capital to buy services from tech firms, and analysts value the whole chain on the assumption that the demand is real and growing. That's not fraud — it's not even unusual. It's how every technological investment wave looks from the inside before you know whether the underlying productivity gains materialise. The BIS is not saying they won't. It's saying the market is priced as if they already have.

Meanwhile, the Fed is not helping. Chairman Kevin Warsh has spooked emerging-market bond investors with hawkish signalling at a moment when falling energy prices had briefly opened the door to easing. The US-Iran ceasefire gave markets a week of optimism — lower oil, lower inflation expectations, breathing room. Then came the weekend: more tension in the Persian Gulf, gold back near $4,000, and the ceasefire looking considerably less permanent than it did on Friday. The window opened. The window may already be closing.

My call: the BIS is right to flag the AI valuation risk, and it will be ignored for another quarter. These warnings always are — until they aren't. The signal worth watching is not the stock price of any AI name, but whether credit conditions tighten for companies that are adjacent to the trade. That's where the stress shows first. If you are sitting on a pension that has significant equity exposure and haven't checked your fund's concentration in tech recently, the Malta pension calculator is a reasonable place to start asking the right questions.

The map is changing. The generals are still studying last year's terrain.
