Report Industry Investment Rating No relevant content provided. Core Viewpoints - On August 22, 2025, key - term treasury bonds were newly issued after the levy of coupon VAT. The coupon rate of 10Y25 Treasury Bond 16 (2516) is 1.83%, and that of 30Y25 Ultra - long Special Treasury Bond 06 (25T6) is 2.15%. Whether 2516 and 25T6 can become active bonds is the key to the rationality of their issuance pricing [1][7]. - For 30Y treasury bonds, there are three possibilities for the next active bond: 25 Ultra - long Special Treasury Bond 02 may remain active throughout the year; the active bond may switch to 25T6; or it may switch to 25 Treasury Bond 02. If 25T6's actual issuance scale is close to the estimated scale, it is likely to become the next active bond and has investment value [2][10]. - For 10Y treasury bonds, 25 Treasury Bond 11 may remain active for some time due to market investment habits, but 2516 has the possibility of quickly switching to the active bond. If it switches successfully, it has certain cost - effectiveness with an implied tax rate of 3.77% when priced with reference to the active bond [3][16]. Summary by Relevant Catalog 1.1 Subsequent 30Y Treasury Bond Active Bond Possibility Analysis - **Estimated Scale of 25T6**: According to the issuance plan, 25T6 will have three more consecutive issuances in September and October. Assuming 20Y and 50Y consecutive issuances are based on the recent issuance scale of 35 billion yuan, 25T6's total scale may reach 317 billion yuan, higher than 25 Ultra - long Special Treasury Bond 05 but slightly lower than 25 Ultra - long Special Treasury Bond 02 [8]. - **Estimated Scale of 25 Treasury Bond 02**: In 2025, 25 Treasury Bond 02 will have two consecutive issuances in November and December. Assuming each issuance is 78 billion yuan, its final scale is expected to reach 273 billion yuan, less than the estimated scale of 25T6 [9]. - **Next 30Y Treasury Bond Active Bond Possibility**: Since 2020, most 30Y treasury bonds can remain active for over 150 days after becoming active bonds, and generally become active within 60 days after the first issuance. The average proportion of the issuance scale when becoming an active bond to the final scale is 54%. There are three possibilities for the next active bond: 25 Ultra - long Special Treasury Bond 02 may remain active, in which case 25T6 may have low value; the active bond may switch to 25T6, which has high cost - effectiveness; or it may switch to 25 Treasury Bond 02, but the probability is low. If 25T6's actual scale is close to the estimated one, it is likely to become the next active bond [2][10]. 1.2 Subsequent 10Y Treasury Bond Active Bond Possibility Analysis - **Historical 10Y Treasury Bond Active Bond Situation**: Since 2020, 10Y treasury bonds generally remain active for about three months after becoming active bonds and usually become active within one month after issuance. Since 2024, the issuance scale has become an important factor affecting whether a 10Y treasury bond can become an active bond [15]. - **Estimated Scale of 2516**: If 2516 is issued consecutively based on the current issuance scale, its final scale is expected to be 462.03 billion yuan, slightly lower than the current active bond 25 Treasury Bond 11, but still a large - scale 10Y treasury bond [15]. - **Possibility of 2516 Becoming Active Bond**: 25 Treasury Bond 11 may remain active for some time due to market investment habits, but 2516 has the possibility of quickly switching to the active bond. After the first consecutive issuance, if it switches successfully, it has certain cost - effectiveness with an implied tax rate of 3.77% when priced with reference to the active bond [3][16].
