The People’s Republic of China has a “national team” of investors who work at the government’s behest to maintain a measure of stability in the PRC’s stock market.

The group is known by market players as the “national team,” and it functions as a market stabilization fund. It has been a fixture in the Chinese stock market for more than a decade, usually buying exchange-traded funds, and was widely noted when it intervened to prop up prices during a 2015 crash. After Trump announced his “liberation day” tariffs in April 2025, triggering a global stock selloff, the national team stepped in to relieve the pain as a buyer of index funds.

In any event, it’s also textbook investing: buy low and sell high. Either way, this is making a lot of money for the PRC government, which in turn provides serious money for subsidizing its cost of goods production and for offsetting the effects of foreign (mostly US) tariffs on PRC exports. More the former, most likely, since the PRC has been able to increase its exports to Europe and South America, to their economic dependency peril.
