The PBoC now has a larger dollar balance sheet (on the asset size) than the Fed. It holds around a trillion dollars of Treasuries and Agencies (over $950b can be identified using the TIC data, and the TIC data understates China’s holdings … ). The Fed has around $900 billion in assets — $940 billion, to be precise.
