China is sitting on a $6 trillion pile of money, half of which is "hidden", and that presents a new kind of risk to the global economy, citing American economist Brad Setser news agency Bloomberg reported. The former US trade and Treasury official wrote in a report on The China Project, a New York-based news platform that a lot of the country’s foreign-exchange reserves don’t show up in the official books of the People’s Bank of China. Instead, what can be called "shadow reserves" appear among the assets of entities such as state commercial lenders and policy banks, Setser said, while adding, while official reserves have flat-lined over recent years, the "hidden" variety have likely pushed higher alongside China’s export surplus.


Setser, who is now a senior fellow at the Council on Foreign Relations, a New York-based think tank, wrote that China’s lack of transparency here is a bit of a problem for the world. "China structurally is so central to the global economy that anything it does, seen or unseen, will eventually have an enormous impact on the rest of the world," he said.


An example of the influence China's reserves can have is their role in funding the country’s Belt and Road Initiative, which stemmed from a post financial-crisis push to diversify holdings, according to the former Biden administration trade adviser.


"They are powerful enough of an economic force such that an entire, global, decades-long infrastructure plan was in some ways, just a side effect of a 2009 decision to find new ways to manage China’s foreign exchange," he wrote. "Well, China is so big an economy – and such an unbalanced economy – that all its activities just have an outsized global impact."


Institutions reporting to the central government probably have closer to $6 trillion in foreign assets, Setser said. That compares with the $3.1 trillion in official reserves the State Administration of Foreign Exchange reported at the end of last year, he added.


The scale of these hidden reserves “highlights an important fact that is often forgotten amid all the talk of China’s domestic debt problems,” he wrote. “Globally China is still a massive creditor, and the weight of China’s massive accumulation of foreign exchange is still felt around the globe.”
