The People's Bank of China (PBoC) announced on Thursday a 500 billion yuan ($70.6 billion) swap facility to "promote the healthy and stable development of the capital market." The facility will support qualified securities, funds and insurance companies to exchange assets such as bonds, stock ETFs and CSI 300 index constituent stocks for assets including treasury bonds and central bank bills.
The PBoC said it could expand the size of the operation if needed. The applications for the facility were open immediately.
