China’s Surprise Reserve Requirement Cut: Liquidity Fine‑Tuning or Policy Shift?

When the People’s Bank of China (PBOC) cut its reserve requirement rate (RRR) by 1% for China’s banks recently, the central bank said its “prudent and neutral policy stance” remained in place, since the overall quantity of excess reserves would not change much. Indeed, the PBOC will maintain a relatively high reserve requirement for China’s banks.

Still, the move caused China’s entire yield curve to drop by 15 basis points (bps) and raised interesting questions about the PBOC’s policy intent.

We believe the action sent an important signal that China’s policymakers will be careful not to overtighten ahead of an expected growth slowdown in 2018. Although it is too early to call this the beginning of an easing cycle, the RRR cut confirms the end of 18 months of continuous liquidity tightening by the PBOC, and thus makes the PBOC’s policy stance not only more neutral but also more flexible.

Lower reserve requirement: a form of monetary easing

Announced on 18 April, the PBOC’s cut lowers the reserve ratio for large Chinese banks to 16% from 17%, effective on 25 April.

According to the PBOC, the 1% reduction will release CN¥1.3 trillion ($206 billion) in excess reserves. While the PBOC will require banks to use the funds to repay CN¥900 billion to its mid-term lending facility (MLF), the remaining CN¥400 billion in reserves will be released to the banks, with the goal of increasing loans to small companies, in particular.

Effectively, this is a loosening of monetary policy by the PBOC. The impact on interbank funding costs are clearly accommodative; banks currently pay an annual rate of 3.30% to borrow from the PBOC’s one-year MLF, so the release of CN¥1.3 trillion in deposit reserves (the PBOC pays 1.62% on required reserves and 0.72% on excess reserves) will lower interbank borrowing costs. We estimate wholesale funding costs should drop by 15 bps – 20 bps after the RRR cut. So the market’s knee-jerk reaction of driving down the yield curve in the days after the announcement was in line.
