The central bank has tightened liquidity to a record level, putting pressure on the bond market.

Overview

Deutsche Bank has issued a fixed-income Asia chart alert, noting that the People’s Bank of China (PBoC) is tightening medium-term liquidity at a record pace. Although the central bank has been injecting short-term liquidity via seven-day open market operations (OMO) to maintain market stability, the continued net drainage of medium-term liquidity signals the ongoing normalization of monetary policy. The report argues that this trend, coupled with the impending maturity of large-scale policy tools and the issuance of government bonds, will tighten liquidity conditions, push up short-term interest rates, and keep the yield curve steep.

Core views

Unprecedented Tightening of Liquidity: Recently, the central bank has net‑withdrawn RMB 1 trillion through buy‑back reverse repos (ORR), marking the largest monthly net withdrawal since this tool was introduced in October 2024. Although it simultaneously injected a modest RMB 100 billion via the Medium-term Lending Facility (MLF), this represents the third consecutive month of net liquidity drainage at the medium term, with cumulative net withdrawals exceeding RMB 2.5 trillion—underscoring the central bank’s clear intent to tighten liquidity over the medium horizon. A “Short‑Long Mix” for Policy Balance: While tightening medium‑term liquidity, the central bank has deployed 7‑day open market operations (OMO) to inject short‑term liquidity, aiming to dampen volatility and maintain market stability. This stance comes amid broadly ample interbank liquidity; with deposit growth outpacing loan expansion, interbank lending rates remain below the central bank’s policy benchmark, providing room for targeted structural adjustments. Outlook for Tighter Liquidity: The report projects that medium‑term liquidity will continue to trend toward net withdrawal in the coming months, driven by two key factors: first, the normalization of monetary policy as the central bank shifts away from an accommodative stance; and second, substantial maturity pressures, with MLF and ORR maturities totaling RMB 5.7 trillion over the next three months. In addition, an aggressive government bond issuance schedule is expected to further absorb market liquidity. Collectively, these dynamics are likely to push the 7‑day repo rate higher and keep the yield curve steep.

Analysis framework

Institutions primarily assess marginal changes in liquidity by monitoring the People’s Bank of China’s open-market operations data, including the net injection or withdrawal amounts associated with instruments such as the ORR, MLF, and OMO. The analytical framework follows the “quantity–price relationship”: first, it identifies the magnitude and persistence of medium-term liquidity withdrawals (the quantity dimension), then, by factoring in the outstanding maturities of these instruments (a supply shock) and the government bond issuance schedule (fiscal drainage), it infers the implications for short-term money‑market rates—such as the 7‑day repo rate—and the shape of the yield curve (the price dimension). This approach represents a quintessential fixed‑income analysis grounded in central bank balance‑sheet dynamics and the interplay between liquidity supply and demand.

  Assessing Liquidity Conditions and Policy Stance

  By examining the divergent operational stances of the central bank’s short-term OMO instruments versus its medium-term MLF/ORR facilities, we can assess whether policy is in a “loose monetary” or “tight monetary” phase and whether structural adjustments are underway. In this analysis, the combination of medium-term tightening alongside short-term stability underscores the finely calibrated calibration inherent in the policy normalization process.

  Yield Curve Steepening

  When short-term liquidity tightens due to liquidity drainage and maturing obligations, the rise in short-term interest rates may outpace that of long-term rates, or the long end may lag behind in responding to economic expectations, leading to a steepening yield curve. Based on this, the research report forecasts an increase in the 7-day repo rate and a steepening of the yield curve.

Key data

• ORR’s monthly net liquidity withdrawal amountRMB 1 trillionSetting a new record since the tool was launched in October 2024.
• Cumulative net withdrawal of medium-term liquidity> RMB 2.5 trillionThe cumulative total after three consecutive months of net liquidity withdrawal
• Outstanding maturities of MLF and ORR over the next three monthsRMB 5.7 trillionThe substantial pressure from maturing debt rollovers will further exacerbate liquidity strains.
• Monthly net MLF injectionRMB 100 billionIts scale is relatively small, insufficient to offset the ORR’s liquidity withdrawal.

Impact & implications

For the fixed-income market, the central bank’s continued net drainage of medium-term liquidity implies that monetary conditions will tighten marginally. With the maturation of a massive RMB 5.7 trillion in policy instruments coinciding with a peak in government bond issuance, excess reserves in the interbank market could come under pressure, thereby pushing up short-term funding costs—such as the 7-day repo rate. The yield curve is expected to remain steep, suggesting that valuation pressures on short‑term bonds may outweigh those on long‑term maturities. Investors should remain vigilant about the risk of capital losses stemming from rising short‑term interest rates.

Risks

• If the central bank unexpectedly increases its short-term liquidity injections to offset maturing obligations, it could result in a smaller-than-expected rise in short-term interest rates.
• If macroeconomic data weaken significantly, it could compel the central bank to revert to a more accommodative stance, thereby altering the current normalization trajectory.

What to watch

• The rollover situation for MLF and ORR maturities over the next few months
• The deviation of the 7-day reverse repo rate (DR007) from the policy rate
• The pace and scale of government bond issuance
• Changes in the growth differential between interbank deposits and loans
