Report Summary 1. Report Industry Investment Rating No industry investment rating information is provided in the report. 2. Core Viewpoints - The value of floating - rate bonds is affected by factors such as changes in the benchmark interest rate, term spreads, and market expectations of interest rate movements. In a rising interest - rate environment, floating - rate bonds are more resistant to price declines compared to fixed - rate bonds, but they perform relatively weakly in a falling interest - rate environment. - Based on simulations of floating - rate bonds, the market expects the 1 - year LPR to decline steadily in the next two years, reaching a low of 2.8% in April 2027, and then rise to 3.1% by the end of 2027. - Considering the potential for additional interest rate cuts in the second half of the year, the allocation value of floating - rate bonds may be lower than that of fixed - rate bonds. Similarly, the current allocation value of DR007 floating - rate bonds may also be lower than that of fixed - rate bonds [167][177]. 3. Directory Summaries 3.1 China's Floating - Rate Bond Historical Changes - **Issuance Scale**: Over the past 30 years, China's floating - rate bond issuance scale has shown a fluctuating upward trend, with three rounds of expansion and adjustment. The issuance scale reached a historical peak of 637.6 billion yuan in 2021, but has significantly decreased in the past three years [14]. - **Benchmark Interest Rate**: It has evolved from a single benchmark (1 - year fixed - deposit interest rate) to a diversified one. Currently, LPR and DR007 are the mainstream benchmark interest rates [20][27]. - **Bond Types**: Policy - bank bonds and asset - backed securities have alternately dominated the market. Since 2022, policy - bank bonds have once again become the main type of floating - rate bonds [34][41]. - **Issuance Term**: The issuance term has changed from being highly concentrated (7 - 10 years) to gradually diversified and then re - concentrated (2 - 3 years) [46][51]. 3.2 Floating - Rate Bond Valuation Method - **Valuation Principle**: Based on the discounted cash - flow method (DCF), the present value of a floating - rate bond is calculated by discounting future coupon payments and the principal at maturity to the current point in time. However, the difficulty lies in predicting future coupon payments and selecting the discount rate [63][64]. - **Factors Affecting Investment Value**: Changes in the benchmark interest rate and term spreads (∆y) affect the value of floating - rate bonds. Generally, an increase in the benchmark interest rate leads to a decrease in bond value, and vice versa. The impact of term spreads on bond value needs to be analyzed in combination with changes in the benchmark interest rate [77][80]. 3.3 Relative Value of Floating - Rate Bonds - **Comparison with Fixed - Rate Bonds**: In a rising interest - rate environment, the price decline of floating - rate bonds is smaller than that of fixed - rate bonds; in a falling interest - rate environment, floating - rate bonds perform slightly worse than fixed - rate bonds [86][94]. 3.4 Absolute Value of Floating - Rate Bonds (Based on Historical Backtracking) - By observing the historical trends of floating - rate bonds with DR007 as the benchmark, it is found that the value changes of floating - rate bonds are complex and are affected by the fluctuations of the National Development Bank bond rate and DR007. When the two rates move in opposite directions, the direction of the floating - rate bond value change is clear; when they are stable, the value center of the floating - rate bond is stable; when they move in the same direction, the direction of the value change is uncertain [101][134]. 3.5 Future Interest - Rate Cut Path Implied by Current Floating - Rate Bonds - By simulating the cash flows of floating - rate bonds, the market's implied interest - rate cut/ hike path for the 1 - year LPR in the next three years can be predicted. The market expects the 1 - year LPR to decline steadily in the next two years, reach a low of 2.8% in April 2027, and then rise to 3.1% by the end of 2027. The implied interest - rate cut expectations of floating - rate National Development Bank bonds are stronger than those of Agricultural Development Bank bonds [154][162]. 3.6 Investment Value of Floating - Rate Bonds - **1 - year LPR Floating - Rate Bonds**: Considering the potential for additional interest rate cuts in the second half of the year, the allocation value of floating - rate bonds may be lower than that of fixed - rate bonds [167]. - **DR007 Floating - Rate Bonds**: Through scenario analysis, it is found that under most scenarios, the current allocation value of DR007 floating - rate bonds is lower than that of fixed - rate bonds [172][175].
