PBoC injects CNY 258bln in overnight reverse repos, while 7-day reverse repo volume is at zero

PBoC injects CNY 258bln in overnight reverse repos, while 7-day reverse repo volume is at zero.

Open market operations of this kind are the PBoC's routine instrument for smoothing interbank liquidity, and the shape of the operation matters more than the gross size: what is priced is the net injection after maturing repos, not the headline number. A shift toward overnight tenor while the standard 7-day operation runs at zero has in past episodes signalled an intent to meet short-dated funding pressure without committing to a longer addition of liquidity, a pattern seen around month-end, tax payment windows, government bond issuance, and holiday cash demand. Concentrating provision at the shortest tenor also keeps the maturity profile rolling over daily, preserving the authorities' discretion to withdraw the support quickly. The channels to watch are the repo fixings and the spread of money market rates over the 7-day policy rate, since persistent tension there despite injections has historically preceded adjustments to standing facilities or reserve requirements rather than a change in the policy rate itself. The follow-ons are the net daily position across the rest of the week, any resumption of 7-day operations, and where the operation sits in the monthly cycle relative to the medium-term lending facility roll.
