——2025年12月债券托管数据点评：交易盘减配态势延续杠杆率季节性上升

1. Report Industry Investment Rating - No information about the industry investment rating is provided in the report. 2. Core Viewpoints of the Report - In December 2025, the bond market remained weak. The ultra - long - end interest rates continued to rise while the short - end rates recovered, steepening the yield curve. The trading desks, represented by securities firms and broad - based funds, continued to reduce their bond allocations, but the reduction intensity of securities firms weakened and they started to increase their allocation to interest - rate bonds. The allocation - oriented institutions such as banks and insurance companies increased their bond allocations, but the scale was limited and difficult to reverse the overall interest - rate trend. The top signal of interest rates might need to wait until the allocation power strengthened to the point where the selling pressure from trading institutions could no longer push interest rates significantly higher [3][13]. 3.
