PBoC keep 7-day reverse repo amount at zero, but injects CNY 470bln via overnight reverse repo operations

Shifting the composition of daily operations between tenors is a familiar PBoC technique for managing liquidity without sending a rate signal. Holding the 7-day reverse repo at zero while injecting through the overnight tenor keeps the banking system funded but shortens the maturity of that funding, which rolls off immediately and gives the central bank maximum flexibility to adjust or withdraw support day to day. In past episodes this pattern has appeared around quarter-end, tax payment dates, or government bond issuance, when transient cash demand rises but the authorities are reluctant to expand the structural liquidity footprint; the 7-day rate, not the volume mix, remains the operative policy signal. The distinction worth drawing is between liquidity provision and policy stance: large gross injections at short tenors have historically coexisted with a neutral or even tight bias, since the overnight leg must be renewed to persist. What matters next is whether the overnight operations repeat and grow, which would point to a genuine funding squeeze in the interbank market, or whether the 7-day returns at an unchanged rate, which would confirm this as routine smoothing. Money market rates such as the 7-day repo fixing and the DR007 spread to the policy rate are the established tells.
