TF Securities(SH:601162) Tianfeng Securities·2025-10-29 23:44Investment Rating - Industry Rating: Outperform the Market (maintained rating) [8] Core Insights - The resumption of government bond trading will primarily lead to asset replacement rather than extending the duration of liabilities for commercial banks. The operations will adjust the asset structure without expanding the balance sheet [2][3][19]. - The impact on the Net Stable Funding Ratio (NSFR) from government bond trading is minimal due to the low net buying scale and the 5% coefficient for government bonds in the NSFR calculation [4][5][26]. - Government bond trading can help alleviate pressure on banks' interest rate risk indicators, providing a feasible option for managing the increasing supply of government bonds [6][28][29]. - The improvement in banks' funding costs from government bond trading is limited, with a potential cost reduction of approximately 1 basis point if the central bank buys 1 trillion yuan of bonds [7][30][32]. Summary by Sections 1. Impact of Government Bond Trading on Bank Asset and Liability Structure - The essence of government bond trading for commercial banks is asset replacement, with liquidity from bond sales being utilized in various ways, including maintaining excess reserves or replacing other monetary policy tools [2][15][19]. - The operations do not lead to a balance sheet contraction but may tighten overall liquidity due to reduced excess reserves [16][19]. 2. Limited Improvement in NSFR - The resumption of government bond trading may not significantly alleviate the pressure on banks' funding costs, as the current high balances of MDS and MLF remain a concern [4][21][22]. - The potential for NSFR improvement is small, with estimates suggesting a reduction in required stable funding of about 500 billion yuan from a net buying scale of 1 trillion yuan [26][27]. 3. Alleviation of Interest Rate Risk Pressure - The increasing supply of government bonds necessitates strategies to manage interest rate risk, including the use of government bond trading as a tool to absorb some of the supply [6][28][29]. 4. Limited Effect on Funding Cost Improvement - The mechanism for improving funding costs involves replacing MDS and MLF with liquidity from bond sales, with a projected minimal impact on overall funding costs [7][30][31].
