China Overhauls Deposit and Loan Interest Rate Rules

China’s central bank has published a sweeping revision of its deposit and loan interest rate regulations, introducing formal definitions for high-interest deposit-taking practices and eliminating rigid penalty interest formulas in a move that experts say marks a decisive shift from industry self-regulation to enforceable legal standards.

The People’s Bank of China (PBOC) released the draft “Regulations on the Management of RMB Deposit and Loan Interest Rates” on June 5, replacing the 1999-era framework that had become increasingly outdated in China’s marketized financial system. The new rules are open for public comment and represent the most significant update to interest rate governance in over two decades, according to Xinhua News.

Cracking Down on High-Interest Deposit-Taking

For the first time, the regulations explicitly define “high-interest deposit-taking” (高息揽储) as an illegal practice, including tactics such as illegal manual interest supplements, breaking self-discipline mechanism interest rate caps, and deposit-loan bundling. These practices had become widespread among Chinese banks—particularly smaller institutions—engaged in intense competition for deposits.

“This inclusion of the definition of high-interest deposit-taking into departmental regulations marks a shift from ‘soft moral suasion’ to ‘hard legal red lines,’ significantly enhancing regulatory binding force,” Tian Xuan, Dean of Peking University Guanghua School of Management, told the Economic Information Daily.

The crackdown builds on an April 2024 initiative by the Market Interest Rate Pricing Self-Discipline Mechanism that banned manual interest supplements. By embedding these definitions in formal regulations, the PBOC creates legal consequences for violations, dramatically increasing enforcement power.

Penalty Interest Overhaul

One of the most significant changes is the elimination of the fixed penalty interest range of 30%-50% above the contracted loan rate for overdue loans—a rule that had been in place since 2003. Under the new framework, penalty interest rates, calculation methods, and grace periods will be negotiated between lenders and borrowers.

An anonymous banking source told Jiemian News that the old system lacked the flexibility needed in a marketized rate environment: “Under the LPR mechanism, loan rates themselves fluctuate significantly. Maintaining fixed percentage surcharges lacks the flexible adjustment mechanism compatible with a marketized rate environment.”

Wang Pengbo, Chief Analyst at Botong Consulting, cautioned that borrower protections should accompany the new flexibility, suggesting banks be required to disclose average penalty interest levels for similar customers to form “soft constraints through transparency mechanisms.”

Mandatory Annualized Rate Disclosure and Calculation Changes

The new rules mandate that financial institutions prominently display annualized interest rates when marketing loan products and in loan contracts—a measure designed to combat “rate illusion” where lenders advertise deceptively low daily or monthly rates.

In a technical but consequential change, the regulations shift interest calculation from a 360-day convention to natural days (365 days, or 366 in leap years), aligning China with international practice and improving transparency.

Implications for China’s Banking Sector

The reforms come at a critical time for Chinese banks. Commercial banks’ net interest margin stood at 1.4% in Q1 2026, down from approximately 2.2% in 2020, though the pace of decline has narrowed significantly.

Lin Yaheng, an analyst at Southern Fund’s Macro Strategy Department, said the new rules will push deposit competition “from ‘competing on price’ to ‘competing on service, products, and customer management capabilities.’” From a macro perspective, this helps promote smoother linkage between deposit rates, market rates, and policy rates, improving monetary policy transmission efficiency.

Small and medium banks, which have historically relied on above-market deposit rates to compete with large state-owned banks, face the greatest adjustment. In the short term, their space to attract deposits through illegal high-interest methods will be compressed. However, as Tian Xuan noted, in the long term, the reforms will force banks to optimize their liability structures and reduce dependence on high-cost deposits.

A Milestone in Interest Rate Marketization

China’s interest rate marketization has been a gradual, multi-decade process—from removing loan rate floors in 2013 to eliminating deposit rate ceilings in 2015 and introducing the LPR benchmark in 2019. These new regulations represent the next logical step: codifying market discipline into enforceable law.

Wang Qing, Chief Macro Analyst at Dongfang Jincheng, told Jiemian News that the central bank is “establishing a clear rule system to gradually build and improve diversified deposit and loan interest rate pricing benchmarks, more effectively constraining irrational competition among financial institutions.”

What to Watch For

Key questions remain about the implementation timeline, enforcement mechanisms, and transition provisions for existing contracts. Market participants will also be watching for any targeted support measures for smaller banks most affected by the changes. The public comment period is now open, with the final regulations expected to take effect later this year.
