1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - From July 28 to August 1, treasury bond yields first rose and then fell due to multiple factors, with the yield curve showing a flattening trend. The resumption of VAT on bonds has a limited negative impact on the bond market, and credit bonds may see value re - evaluation opportunities. The tax advantage of public funds over bank self - operations is further enhanced, which may drive the outsourcing demand of bank self - operations. Next week, fund rates are expected to remain stable, while the supply pressure of treasury bonds will increase. The current bond market strategy suggests maintaining a defensive stance and seizing structural opportunities [2][3][7]. 3. Summary According to the Directory 3.1 Bond Market Weekly Review - From July 28 to August 1, treasury bond yields first rose and then fell. The fund - side was first loose and then tight, remaining generally loose. Important policy events were successively implemented, and the manufacturing PMI in July fell below the boom - bust line. Overall, yields of treasury bonds across various maturities generally declined. For example, the yields of 1 - year, 10 - year, and 30 - year treasury bonds decreased by 1.01BP, 2.65BP, and 2.35BP respectively, and the yield curve showed a flattening trend [2][12]. 3.2 Bond Market Data Tracking 3.2.1 Fund - side - From July 28 to August 1, the central bank's open - market operations had a net injection of 69.00 billion yuan. The central bank conducted 16,632.00 billion yuan of open - market reverse repurchases, with 16,563.00 billion yuan maturing. The fund - side was stable across the month, and the fund rate center declined. The differences in fund costs between non - bank institutions and banks increased, and the term spread of FR007S5Y - FR007S1Y converged [23][24]. 3.2.2 Supply - side - From July 28 to August 1, the total issuance of interest - rate bonds decreased, while the net financing increased.

For credit bonds, seize the value re - evaluation opportunities brought by the resumption of VAT on interest - rate bonds. In the convertible bond market, focus on equity - balanced varieties. This week, pay attention to the primary - market issuance results of local government bonds on August 8, the central bank's liquidity injection through various tools in July, and inflation data [7][61]. 3.4 Global Major Assets - As of August 1, 2025, yields of US treasury bonds generally declined, and the term spread widened.
