利率走廊收窄的债市含义 20251118 理想中的短期利率走廊应具备以下特征：一是能够有效控制市场基准利率如 DR007 等波动区间，使其围绕政策目标稳定运行；二是具有灵活且透明的调控 机制，以便及时应对市场变化；三是涵盖广泛，包括商业银行及非银机构，以 确保全面覆盖金融体系各类参与者。 可以借鉴美联储经验。在 2008 年次贷危 机前，美联储通过日常 OMO 操作使实际联邦基金有效利用 EFFF 围绕目标波动， 实现精准管控。次贷危机后，由于 QE 导致银行间流动性过剩，美联储创设 IORB 与 ONRRP 组成新的地板系统，通过这些工具调整市场流动性。因此，我 国央行可考虑类似方式，通过日常精准投放与新型工具组合，提高资金面稳定 性与预见性，从而增强金融服务实体经济效能。 收窄短期利率走廊会对债市产生哪些具体影响？ 潘功胜行长在十五规划学习材料中提到要收窄短期利率走廊的宽度，这对央行 货币政策操作和债市定价有何影响？ 潘功胜行长提到收窄短期利率走廊的宽度，这将对央行货币政策操作和债市定 价产生深远影响。目前，人民银行已初步形成以 7 天逆回购利率为基准政策利 率、DR007 为基准市场利率的货币政策调控框 ...

Report Summary 1) Report Industry Investment Rating No industry investment rating is provided in the report. 2) Core Viewpoints of the Report - The adjustment of the 14D OMO reverse - repurchase tender method can better stabilize the short - end fluctuations of the yield curve and maintain the abundance of bank system liquidity [2]. - It is expected that 14D OMO operations will be more frequent than before, and the first 14D OMO operation after the change of the tender method may be carried out on September 22, 2025 [2]. - Attention should be paid to real - time DR and CD interest rates rather than privately inquired winning bid rates of 14D OMO, as the latter contains limited monetary policy information and is often lagging [3]. - Moderately narrowing the interest rate corridor can reduce DR fluctuations and improve the efficiency of interest rate regulation, and currently, there are basic conditions to narrow the interest rate corridor by moderately reducing the SLF interest rate [3][4]. 3) Summary by Relevant Catalogs Event - On September 19, 2025, the People's Bank of China announced that, starting from that day, the 14 - day reverse - repurchase operation in the open market would be adjusted to fixed - quantity, interest - rate tender, and multi - price winning bids [1]. Comment - The 7D OMO interest rate is the main policy interest rate in China. The new combination of 7D OMO (fixed - interest, quantity tender) and 14D OMO (fixed - quantity, interest - rate tender, multi - price winning bids) can better stabilize the short - end fluctuations of the yield curve and maintain the abundance of bank system liquidity [2]. - It is expected that 14D OMO operations will be more frequent than in previous years, not limited to before the Spring Festival and National Day. The first 14D OMO operation after the change of the tender method may be carried out on September 22, 2025. In the future, some investors may be interested in privately inquiring about the winning bid rate of 14D OMO, but these rates contain limited monetary policy information, and attention should be paid to real - time DR and CD interest rates [2][3]. - 7D and 14D OMO are the "new partners" for maintaining liquidity abundance, and the interest rate corridor is the "old assistant" for suppressing short - end fluctuations. Moderately narrowing the interest rate corridor can reduce DR fluctuations and improve the efficiency of interest rate regulation. There are two ways to narrow the interest rate corridor: the natural compression when the 7D OMO interest rate and SLF decline together, and the reduction of the spread of the SLF interest rate above the OMO interest rate [3]. - Currently, there are basic conditions to narrow the interest rate corridor by moderately reducing the SLF interest rate. From May to August 2025, the SLF operation volume was much smaller than the inter - bank pledged repurchase trading volume. The minimum value and 10% quantile of the spread between the 7D SLF and DR007 from early 2024 to September 19, 2025, were at a moderate and relatively large level [4].
