The Bank of England is investigating rapid growth in London-based investment
banks' exposure to Asian equities; officials say they want to avoid highly
concentrated bets on a handful of AI-related names. Hedge funds and other
institutions have been channeling capital into companies supplying AI
semiconductor infrastructure in Asia, including SK Hynix and TSMC. The central
bank says these Asian stocks are becoming an increasingly significant part of
major UK brokers' books and appear concentrated in a small set of AI-linked
firms. Clients may be taking additional risk through high‑leverage option
positions in Asian markets, and some institutions may be raising capital from
Asian retail investors to fund trading — a potential liquidity vulnerability if
those retail holders sell quickly in a stress event.
