PBOC Solicits Comments on New Interest Rate Rules; Positive for Bank NIMs

Overview

This report interprets the draft 'Rules on the Administration of RMB Deposit and Loan Interest Rates' released by the People's Bank of China (PBOC) on June 5, 2026. Morgan Stanley believes these new regulations aim to establish a clearer market-based pricing rule system and combat unfair competition by clarifying financial institutions' independent pricing rights and the PBOC's regulatory responsibilities. The research team holds a positive view, believing the new rules will help optimize the banking sector's competitive environment, support net interest margin (NIM) trends, and thereby drive revenue recovery and stable profit growth in China's banking industry.

Core views

The core of the new regulations lies in establishing principles of market-based pricing and fair competition. The draft explicitly allows financial institutions to independently set deposit and loan rates based on PBOC regulations and commercial principles, while emphasizing that the PBOC and its branches should strengthen supervision and guide the market interest rate self-regulatory mechanism. On the deposit side, the new rules explicitly prohibit high-interest deposit solicitation, including unauthorized manual interest subsidies, breaches of self-regulatory caps, and deposit-loan linkages, to prevent disorderly competition in the deposit market. On the loan side, lending institutions are required to clearly display the annualized comprehensive cost, including interest and related fees, as well as the annualized penalty interest rate; the previous fixed base-plus-points model for penalty interest is adjusted to a negotiated rate. In terms of industry impact, the report views these new regulations as a positive catalyst for the banking sector. By regulating competition on the liability side and increasing transparency in asset-side pricing, the new rules are expected to alleviate the pressure from irrational price wars previously faced by banks, thereby improving NIM performance on both asset yield and funding cost fronts. This institutional improvement is seen as a comprehensive upgrade to the outdated 1999 framework, integrating scattered interest calculation and settlement rules and removing administrative restrictions on interest rates other than those for deposits and loans. This marks a new stage in interest rate liberalization reform, laying an institutional foundation for the long-term steady operation of China's banking sector.

Analysis framework

The report adopts an analytical approach combining policy interpretation with fundamental industry transmission mechanisms. It first outlines the institutional changes in the new regulations compared to the 1999 framework, identifying two core regulatory directives: 'prohibiting high-interest deposit solicitation' and 'transparency of loan costs.' Subsequently, it maps these policy changes onto a key metric in bank financial statements—the Net Interest Margin (NIM)—deducing potential impacts on bank profitability from two dimensions: maintaining asset-side yields and controlling liability-side costs, ultimately deriving an investment view at the sector level.

Methodology notes

  Decomposition of NIM Drivers

  Net Interest Margin is a key indicator measuring bank profitability, calculated as the difference between the average yield on interest-earning assets and the average cost of interest-bearing liabilities. This report analyzes the dual impact of regulatory policies on 'asset-side yields' and 'liability-side costs' to assess the combined effect of the new rules on bank NIM trends, representing the most core analytical paradigm in banking sector research.

  Analysis of Capital Price Competition Under Regulatory Constraints

  In the banking sector, deposits are a core supply factor. When regulation loosens, vicious competition such as 'high-interest deposit solicitation' can easily emerge, driving up industry-wide costs; conversely, when regulation tightens (as with the current ban on unauthorized interest subsidies), it essentially reshapes competition rules on the capital supply side. Understanding this shift in supply-side constraints is key to determining whether banks can realize policy dividends.

Impact & implications

The report suggests that the implementation of the new regulations will provide structural benefits to China's banking sector. On one hand, strictly prohibiting high-interest deposit solicitation helps reduce banks' rigid liability costs and curb disorderly competition in the deposit market. On the other hand, standardizing and increasing transparency in loan pricing helps reduce implicit concessions and irrational low-price lending, protecting reasonable asset yield levels for banks. Overall, this shift in the policy environment is viewed as a crucial institutional safeguard supporting the continued recovery and stable profit growth of China's banking sector, reinforcing the attractiveness of current sector allocation.
