China banks: China bank daily: bank bond buying remained large in August as the PBOC reaffirmed moderately loose policy

Overview

This China-bank daily reviews August bond-custody flows, the PBOC's policy message, and the nationwide rollout of cross-border cash pooling. It also provides UBS's existing valuation and rating snapshot for covered A- and H-share banks.

Core views

China's bond market continued to expand in August, although the pace slowed. Total custody increased RMB1.51trn month on month, RMB750bn less than the July increase. Commercial banks supplied more than half of the incremental demand, making RMB857.4bn of net purchases, slightly below July's level, with a preference for rate bonds rather than credit bonds. Broader funds remained active, adding RMB484.7bn, RMB120bn more than in July, while overseas institutions and insurance companies reduced custody positions. The slowdown was broad across bond categories. Rate-bond custody increased RMB1.08trn, down RMB500bn from the prior month, and credit-bond custody rose RMB233.9bn, down about RMB156bn. Negotiable certificate of deposit custody reached RMB19.47trn; its monthly increase narrowed RMB56.4bn to RMB130.74bn. Overall bond-market leverage fell 0.15 basis points month on month to 105.28%. On policy, UBS highlights Pan Gongsheng's statement that the PBOC will implement moderately loose monetary policy to support an environment favorable to economic growth. The PBOC also emphasized two-way market access and improved cross-border payment services to facilitate RMB internationalization. Separately, the nationwide centralized cross-border cash-management rules introduced on 14 September have enabled foreign lenders including HSBC, Standard Chartered and DBS to launch initial nationwide cash-pooling transactions. The framework reduces entry barriers, streamlines registration and allows more flexible pool ratios, which the report says can improve corporates' liquidity allocation and lower funding costs. Other sector developments include growing foreign participation in China's interbank bond market: Panda-bond issuance totaled RMB213.98bn in the first eight months and 29 additional foreign institutions obtained access. The report also notes continued rural-bank consolidation: the total number of rural banks fell to 986, more than 600 below the 2021 peak, with 183 exits through mergers, restructurings or dissolutions in 2026. It cites SPDB and Minsheng as acquiring rural subsidiaries for conversion into direct branches, while state-owned banks have largely completed exits from rural-bank entities. The accompanying valuation table presents UBS's existing ratings and price targets across China-bank coverage as of 22 September 2026. UBS values H-share China banks using a three-stage dividend discount model and A-share banks, including Bank of Ningbo, through a P/B-to-ROE methodology. The table shows a range of implied outcomes, including Buy-rated MSB-A at 34.3% implied upside, CMB-A at 29.8%, and Sell-rated Huaxia at negative 18.3%; these are security-specific coverage figures rather than a new sector call.

Analysis framework

The report compiles recent market and policy news, compares August bond-custody changes with July, breaks flows down by investor type and bond category, and links policy and cross-border operating changes to banking-sector conditions. Its accompanying coverage table applies DDM valuation to H shares and P/B-to-ROE valuation to A shares.

Methodology notes

• Valuation methodsDDM (Dividend Discount Model)

  Three-stage dividend discount model for H-share China banks

  UBS derives H-share bank price targets by estimating dividends through three stages and discounting them to present value.

• Valuation methodsPB valuation

  P/B-to-ROE valuation methodology for A-share China banks

  UBS sets A-share bank valuation by relating price-to-book multiples to expected return on equity.

Impact & implications

The report presents continued, though slower, bank demand for bonds alongside a moderately loose policy stance. It also indicates that easier cross-border cash management may support corporate liquidity efficiency and funding-cost management, while consolidation continues to reshape the rural-bank landscape.

Risks

• China-bank asset quality could deteriorate if the macro environment and domestic property activity weaken.
• Capital, liquidity and off-balance-sheet regulation could create regulatory risk for banks.
• Loan rollovers and longer asset duration could weaken funding structures and balance-sheet liquidity.
• Medium-term interest-rate liberalization could pressure bank profitability.
