Shares of AIA slipped almost 9 %, while Prudential’s Hong Kong‑listed stock fell close to 6 % after a 6.4 % drop in London. HSBC and Standard Chartered fell 2.3 % and 1.7 % respectively. The decline followed a Caixin report that Beijing and Hangzhou applied a 20 % income‑tax rate on dividends and interest from offshore insurance policies.

The policies, large cash cows for insurers selling to mainland Chinese savers, resemble long‑term investment products and are a popular means to move wealth outside China’s capital controls. “More clarity around tax collection is probably what’s driving this, rather than preventing capital movement,” a Hong Kong insurance insider said. Insurers are holding “emergency meetings” as the tax shift threatens a major revenue source.

Runs also include tighter rules on offshore trusts, a 20 % rate at multiple stages, and a global hunt for unpaid taxes on overseas assets. Hong Kong insurers posted a record $42 bn in new life‑insurance business last year, with HSBC and Hang Seng leading the market. Citi analysts say the change resolves a longstanding ambiguity but warn the sell‑off may be “panic‑driven and overdone,” noting structural demand remains intact.
