Core Viewpoint - The article discusses the dual pressures of expected interest rate cuts and the impact on bank interest margins, highlighting the focus on the structural reduction of banks' funding costs [3]. Group 1: Interest Rate and Deposit Management - The recent discussions around the self-discipline mechanism for market interest rate pricing aim to strengthen management of interbank deposits, particularly focusing on limiting the proportion of interbank demand deposits exceeding the 7-day reverse repo rate [4]. - The self-discipline management of interbank demand deposit rates is expected to be upgraded, with previous initiatives having already led to a significant reduction in interbank funding costs for listed national banks by approximately 30-40 basis points [4][5]. - The rapid growth of non-bank deposits, which increased by 2.84 trillion yuan in the first two months of the year, has raised concerns about the transparency and pricing of interbank deposits [3][8]. Group 2: Regulatory Impact and Market Dynamics - The new regulations have led to a sharp decline in the growth rate of interbank deposits from 44% in November 2024 to 5.3% in January 2025, although the growth rate rebounded to 48.9% by January this year [5]. - Analysts suggest that the impact of the new regulations is primarily a one-time effect, and further upgrades to the self-discipline requirements are necessary to ensure long-term constraints on interbank deposit pricing [5][6]. - The current assessment method for interbank demand deposit pricing may shift from a weighted average to a single transaction assessment, which could address the issue of excessive deviation from policy rates [7]. Group 3: Bank Funding Costs and Market Position - As of the third quarter of 2025, the total scale of interbank deposits for listed banks was approximately 29 trillion yuan, with the overall market scale estimated at 40-50 trillion yuan [11]. - The potential adjustment of interbank demand deposit rates could lead to a reduction in funding costs, with estimates suggesting a decrease from 1.5%-1.6% to around 1.4%, which would have a limited overall impact on banks' net interest margins [11][12]. - The major state-owned banks and joint-stock banks are expected to be the most affected by the regulatory changes, as they hold a significant portion of the interbank demand deposits [12].
