China insurers seen driving stock market selloff

The critical shift is in who is doing the selling. Margin financing has already declined and northbound turnover through Stock Connect has weakened, making leveraged traders and foreign “hot money” a less convincing explanation for the latest slide. That leaves long-only institutions — especially insurers — as a more plausible source of the pressure.

That matters because insurers were among the groups policymakers encouraged to channel more money into equities to provide long-term capital to the market. China Life Insurance Co. lifted its equity allocation to 19.2% of portfolio assets by the end of June, up from 16.9% in 2025, while state-owned peers also expanded stock exposure in search of higher returns. But insurers are not the “national team,” Beijing’s stabilizing buyers of last resort. They still have liabilities to meet, and when losses mount, they can be forced to cut risk rather than keep buying.

Authorities have now reportedly told several major insurers to disclose holdings, avoid crystallizing losses and align investments with broader policy goals. That is an awkward turn for Beijing, which is now grappling with an unintended consequence of its own push to make insurers more active stock-market participants. China Pacific Insurance Group has already acknowledged on its earnings call that equity investing has become “complicated,” while third-quarter profits at the country’s five largest listed insurers plunged, largely because of falling domestic stocks.

For investors, the message is that Beijing can lean on policy support, but it cannot easily override the balance-sheet logic of institutional sellers. If insurers are forced to de-risk during sharp drawdowns, then the market’s support base may be less stable than policymakers want. That keeps alive the risk of further forced stabilization measures — and raises the odds that each rally will be met by another round of profit-taking from institutions trying to protect capital.

The broader narrative is increasingly familiar: China has had at least three major bear markets in the past decade that ended in emergency intervention, in 2018, 2024 and now. The unresolved question is whether the next rescue can restore confidence, or whether Beijing will again have to blame outsiders after its own policy mix helped create the conditions for the selloff.
