The People’s Bank of China (PBOC) has adjusted its open market operations, ending a two-month run of expanding its three-month buyout reverse repo instruments and switching to an equal-volume rollover model. Announced on September 4, the central bank will inject 500 billion yuan via a three-month term to match an identical volume maturing during the month, signaling a precise calibration of short-term banking liquidity.
PBOC Shifts Open Market Operations as 3-Month Buyout Reverse Repos Transition to Equal-Volume Rollover
The Bottom Line
- Policy Pivot: The central bank terminated consecutive two-month expansions of 200 billion yuan injections, opting instead for a 500 billion yuan equal-volume rollover of maturing three-month buyout reverse repos.
- Short-Term Tightening: To prevent market rates from drifting too far below policy benchmarks, the PBOC scaled back short-term seven-day operations, achieving a net liquidity withdrawal of 1411.5 billion yuan for the week ending September 4.
- Stability Indicators: Benchmark money market gauges such as the DR001 weighted average rate held soft at 1.3593% at the September 4 close, reflecting ample early-month banking sector liquidity.
Calibrating the Liquidity Taps: Inside the PBOC Shift
The monetary authority’s latest operational calendar reveals a distinct shift toward fine-tuning rather than aggressive net injection. According to an announcement made on September 4, the PBOC will conduct a 500 billion yuan buyout reverse repo operation on September 7 using fixed-quantity, rate-tendering, and multiple-price winning methods. Because exactly 500 billion yuan in similar three-month instruments mature this month, the transaction represents a flat, equal-volume rollover.
Here is the math. Over July and August, the central bank utilized these three-month tools as a net expansion mechanism, boosting operations by 200 billion yuan each month. By freezing that expansion at 500 billion yuan for September, the PBOC is signaling a deliberate cooling of medium-term liquidity injections. But the balance sheet tells a broader story across the entire weekly liquidity cycle.
Wind statistics show that for the week spanning August 31 to September 4, the PBOC executed 816 billion yuan in total reverse repo operations, including limited seven-day short-term tools. Against that injection sat a massive 2227.5 billion yuan in maturing operations, yielding a net weekly withdrawal of 1411.5 billion yuan.
| Indicator / Instrument | Volume / Rate (as of Sept 4) | Operational Trend |
|---|---|---|
| 3-Month Buyout Reverse Repo (Sept 7 Operation) | 500 billion yuan | Equal-volume rollover (matching maturing volume) |
| Prior 3-Month Operations (July–August) | +200 billion yuan monthly expansion | Terminated in favor of flat rollover |
| Weekly Net Liquidity (Aug 31–Sept 4) | -1411.5 billion yuan net withdrawal | 816 billion yuan injected vs. 2227.5 billion yuan matured |
| DR001 Weighted Average Rate | 1.3593% | Stable, trading below 1.40% policy rate |
| DR007 Weighted Average Rate | 1.3726% | Aligned tightly with short-term corridor |
Targeting the Policy Corridor and Managing Short-End Rates
Market watchers note that the adjustment is designed to keep key money market rates tethered to official policy targets. Facing minimal short-term maturities for the week of September 7 to 11—totaling just 10 billion yuan split across Monday and Tuesday—the PBOC proactively reined in its short-term footprint.
The central bank dropped its seven-day reverse repo injection to a meager 5 billion yuan on September 1, followed by three consecutive days of complete suspensions from September 2 to September 4. This sequence was deployed to stop market yields from sliding excessively below official benchmarks.
“9月3个月期买断式逆回购等量续作，也在一定程度上体现了这一调控取向,” Wang Qing, Chief Macro Analyst at Orient Gold Credit Rating (东方金诚), observed regarding the flat rollover. Wang pointed out that benign early-month liquidity combined with modest government bond issuance kept the DR001 hovering near 1.35%, noticeably softer than the 1.40% policy rate.
Data from the close of trading on September 4 underscores this tranquil pricing environment. The DR001 weighted average rate settled at 1.3593%, while the DR007 landed at 1.3726%. Concurrently, overnight Shibor and seven-day Shibor rested at 1.3620% and 1.3760% respectively.
Forward Outlook and Fiscal Coordination
Ming Ming, Chief Economist at CITIC Securities, emphasized that the central bank is practicing forward-looking liquidity management, matching tool volumes directly to actual banking sector demand while one-year negotiable certificates of deposit remain anchored near 1.48%.
Wang Qing added that upcoming macroeconomic support will likely shift toward growth-stabilization efforts. Accelerated government bond issuance and the deployment of 800 billion yuan in novel policy financial instruments will require robust central bank backing. Consequently, market participants anticipate that medium-term tools such as the Medium-term Lending Facility (MLF) and buyout reverse repos could resume expansionary rollovers to facilitate sovereign debt absorption and commercial bank lending.
