BEIJING — China’s central bank injected liquidity into the money market through reverse repos on Jan 15 to offset the impact of a tax payment peak this month.

The People’s Bank of China (PBOC) conducted 80 billion yuan ($11.84 billion) of seven-day reverse repos at an interest rate of 2.55 percent and 100 billion yuan of 28-day reverse repos at 2.85 percent.

No reverse repos will mature on Jan 15, meaning the net market injection was 180 billion yuan.

The PBOC said in a statement that the operation on Jan 14 was aimed at maintaining reasonable and sufficient liquidity in the banking system.

With the peak of tax payments kicking in this month, the PBOC expects liquidity in the banking system to slide fast in the coming days.

Reverse repos enable the central bank to purchase securities from commercial banks through bidding with an agreement to sell them back in the future.

According to an announcement earlier this month, the PBOC will cut the reserve requirement ratio (RRR) for RMB deposits by 0.5 percentage points on Jan 15 before reducing it by another 0.5 percentage points on Jan 25.

Additionally, the medium-term lending facility (MLF) set to mature in the first quarter of 2019 will not be continued, which will unleash about 800 billion yuan of capital into the market.

Given that the 0.5-percentage point RRR cut on Jan 15 will unleash about 750 billion yuan, while a 390 billion yuan batch of MLF will mature, the net liquidity injected into the banking system will stand at 360 billion yuan, Wang Qing, chief analyst with Golden Credit Rating International, told Securities Daily.

The central bank has been using the MLF to channel funds more directly to sectors of the economy that need it most.
