1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - Since the second quarter, the bond market has been in a sideways shock. After the double - cut in May, the interest rate increased slightly, with the 10Y Treasury bond yield rising from 1.62% to 1.72%. During this period, there are two characteristics of institutional behavior: banks' bond allocation reached a record high, and institutions' overall willingness to hold bonds is strong [3]. - In May, the bond allocation of banks reached a record high, mainly due to the peak of supply and changes in the caliber. The net financing of Treasury bonds exceeded 90 billion yuan, and commercial banks' holdings of Treasury bonds increased by over 90 billion yuan, with the increase in all bond types reaching about 1.72 trillion yuan, a record high for commercial banks. Adjusting for the caliber change, the high increase in banks' bond holdings in May may indicate that their willingness to sell bonds to adjust floating profits in the second quarter is relatively controllable [3]. - Institutions' overall willingness to hold bonds is strong, different from previous months. In previous months when interest rates rose, non - bank institutions such as broad - based funds usually reduced or decreased their bond allocation. However, in May, the bond allocation scale of broad - based funds was still significant, with a monthly托管 increase of over 90 billion yuan. Broad - based funds are showing trading characteristics of allocating to certificates of deposit, reducing holdings of Tier 2 capital bonds, buying local government bonds, and conducting band - trading on Treasury bonds and policy - financial bonds. Insurance institutions had a relatively low overall allocation scale in May, securities companies slightly reduced their positions, and foreign investors' holdings of certificates of deposit declined [4]. 3.
