Is China still accumulating dollar assets through its state banks?
Core argument: China's big state-owned financial institutions added an unprecedented $100bn to foreign assets in December and another $70bn in January, warehousing the dollars China Inc bought in the market.
The formal foreign exchange reserves of China’s central bank have not been rising rapidly, but do not be fooled. The dollars that China Inc bought in the market in the past few months are being warehoused by the country’s big state-owned financial institutions, which added an unprecedented $100bn to foreign assets in December and another $70bn in January. These huge, market-moving numbers showed that China’s massive trade surplus once again flows through the balance sheet of its core state financial institutions. Exporters now want to sell their dollars for renminbi to capture the renminbi’s expected appreciation. To offset that demand for renminbi, China’s state banks had to buy a ton of foreign exchange. [Though] the number of Treasuries that Chinese investors hold in US custodians has fallen sharply over time, that does not mean that China’s state — broadly defined — stopped accumulating dollars. Rather, dollar asset accumulation has shifted from China’s State Administration of Foreign Exchange agency (SAFE) ($3.4tn in foreign exchange reserves,an estimated 50-55% [of which are] in dollars) to the state banks (about $3tn in assets, with maybe 70% in dollars, according to my estimates from China’s own data for the commercial banks). If Chinese state investors are not directly buying Treasuries, they are lending money to other global investors who are. That is the only way the global flow of funds can add up.
