Bank of England Probes Asian Equity Exposure: Concerns Over AI Concentration

The Bank of England, the central bank of the United Kingdom, has launched an investigation as investment banks (IBs) operating in London rapidly increase their exposure to Asian equities. The move aims to prevent excessive concentration of Asian equity investments in a small number of artificial intelligence (AI)-related companies.

On July 29 (local time), the Financial Times (FT) reported that the Prudential Regulation Authority (PRA), a subsidiary of the Bank of England, has begun reviewing the prime brokerage operations of London-based financial firms. Sources explained that the review is intended to determine whether exposure to Asian equities is overly concentrated in specific stocks.

Prime brokerage refers to the comprehensive suite of financial services provided by securities firms to institutional clients such as hedge funds, including securities lending, margin lending, and custody services. Once considered a niche business, prime brokerage has scaled up as the valuations of AI-related firms have soared. As clients' equity values have risen, the size of loans collateralized by these holdings has also grown.

The Bank of England is expressing concern over the rapid growth of Asian equity exposure among UK prime brokers. In particular, it sees investment risks as being excessively concentrated in a handful of AI-related companies.

Institutional investors, such as hedge funds, are rapidly ramping up investments in key players within the AI semiconductor industry, including SK hynix, Taiwan's TSMC, and China's Cambrian (Cambricon). However, these stocks are highly volatile, and if their share prices plummet, the risk of losses could spread to major banks. This is because, in leveraged investments, rapid losses could leave clients unable to repay their debts. On July 28, the share price of SK hynix plunged roughly 15%, wiping out over 100 billion dollars in market capitalization.

Concerns have also been raised that prime brokerage clients are expanding high-risk leveraged investments in the Asian market using options. Some reportedly raise funds from Asian retail investors—who can withdraw capital rapidly in a crisis—to use in their trading activities.

Depending on the findings of its inspection of banks and investors, the Bank of England may send letters to each company’s Chief Risk Officer (CRO). Additionally, the FT reported that if the central bank deems a general industry warning necessary, a senior official could issue a public address. However, sources noted that if the issue is confined to select banks, it is likely the authorities will respond through direct supervisory consultations with the relevant firms.
