- At the end of May, the Chinese bill market saw a significant rebound in rediscount rates on the last trading day. The one-month short-term bill rate jumped sharply from near-zero levels of 0.01% earlier in the week to about 0.7%. The six-month national bank acceptance bill rate also rose to around 0.72% to 0.73%, reflecting that financial institutions' credit scale adjustments at the end of the month may have largely concluded.
- This overall rise in rates occurred against a backdrop of persistently weak effective credit demand. Although the People's Bank of China (PBOC) had given verbal guidance to some commercial banks last week to increase credit issuance, banks mainly relied on boosting bill assets to meet regulatory assessments and internal targets due to pressure on real financing willingness.
- Market traders are divided on future trends. Some institutions believe the rebound in rediscount rates may suggest that short-term allocation funds are largely in place. Others point out the expectation of new counter-cyclical adjustment policies over the weekend, with the direction of interest rates after the month-end still depending on the initiation of June credit projects.
End-of-Month Supply and Demand Reversal Drives Rate Increase
This week, the Chinese bill market experienced significant volatility. In previous trading days, due to the lack of significant improvement in May's real economy financing demand, most commercial banks bought large amounts of bills in the secondary market to fill end-of-month credit scales, causing a severe supply-demand imbalance. As a result, rediscount rates fell sharply, with one-month short-term bill rates even hitting historical lows. However, on May 29, major banks suddenly tightened their buying, leading to a rapid rebound in bill rates across all maturities, with major maturities returning to the 0.6% to 0.7% range. Traders noted that this broad rebound largely indicates that major financial institutions have mostly achieved their scale allocation targets.
Pressure on Real Financing Demand Triggers Institutional Volume Boosting
The current volatility in the bill market reflects deeper structural issues at the macroeconomic level. After a negative growth in new RMB loans in April, credit issuance in May still faces significant resistance. Although sources revealed that regulators initiated window guidance last week, urging banks to strengthen credit support for the real economy, in the absence of quality credit projects, commercial banks often choose to expand bill discounting and rediscounting to avoid assessment pressure. This structural volume boosting behavior is particularly evident in the middle and end of the month, directly leading to a temporary deviation between bill rediscount rates and overall market rates.
Rising Policy Expectations and Cross-Month Funding Game
Regarding the unusual rebound on the last trading day, there are speculations within the market about policy changes. Some traders believe that mere completion of scale adjustments cannot fully explain such a sharp overall rate increase, and the market may be pricing in risks for the upcoming weekend policy window. If more targeted monetary or fiscal support measures are introduced in the coming days, market expectations for the start of June credit will be reassessed. In the short term, routine cross-month funding changes typically cause seasonal rate increases, but since rediscount rates are currently at relatively high levels, further upward space is expected to be constrained by supply and demand willingness on both ends.
Regulatory Evolution and Market Structure Deepening
Over a longer time span, the operational mechanism of China's bill market has undergone significant institutional optimization in recent years. Since the China Banking and Insurance Regulatory Commission and the People's Bank of China revised relevant management measures in November 2022, the maximum maturity of commercial bills has been strictly limited to within six months, with a substantial strengthening of real trade background review requirements. Meanwhile, since the national unified bill trading platform, the Shanghai Bill Exchange, officially opened in December 2016, its functions have continued to deepen, and it successfully completed the integration of paper and electronic bill trading in 2018. These foundational improvements have made the bill market's signal effect in conveying central bank monetary policy intentions and reflecting the liquidity surplus or shortage in the banking system more sensitive and transparent.
