BIS flags AI exuberance and debt fragilities as dual headwinds

The Bank for International Settlements told markets this week that AI exuberance and rising debt loads are compounding existing fragilities in the global financial system. The intervention comes as sovereign wealth funds managing $29 trillion pivot away from public equity and toward private credit, infrastructure, and energy assets—a reallocation driven by both national security concerns and stock market concentration risk.

The BIS warning centers on stretched valuations in a narrow cohort of AI-exposed names. That concentration has made public benchmarks more brittle, and sovereign investors are responding by exiting. According to the Financial Times, many of the largest funds now see private markets as the better path to capture AI capex without the volatility of a few dozen mega-cap stocks. The IMF's outgoing chief economist added that shifting trade ties and persistent uncertainty are making the macro backdrop harder to read, even for institutions with decade-long time horizons.

At the same time, European money markets are repricing rate expectations. Three-month Euribor hit a fresh seven-and-a-half-year high this week, a signal that interbank funding costs remain elevated despite hopes for a dovish turn from the ECB. The combination of tighter European funding conditions and continued dollar strength is forcing allocators to reassess currency exposures and liquidity buffers.

Sovereign funds' move into energy and infrastructure reflects more than portfolio diversification. It is a bet that real assets will outperform paper claims in an environment where geopolitical fragmentation is accelerating and monetary policy remains unsettled. The BIS has now named that shift as part of the risk map, not a hedge against it.
