From Goldman’s Yu Song:
Domestic media (Sina) reported that the PBOC conducted RMB 500bn of Standing Lending Facility operations with the big 5 commercial banks (ICBC, BOC, BoCOM, CCB, ABC). The reports note that the duration is 3 months and the RMB 500 bn is evenly split among the banks. This amount is roughly the same as a 50 bps cut to RRR for the whole banking system on a static basis (though the impacts of RRR cuts tend to be larger because they have ongoing effects).
