The amount of credit bonds with a downgraded implied rating in the ChinaBond market increased year - on - year, while the amount of upgraded ones was lower than the same period last year [9][37][38]. Summary by Relevant Catalogs Valuation Curve: Yields Fluctuated Widely and Rose - As of September 23, 2025, the yields of 1 - year Treasury bonds, 10 - year Treasury bonds, and 10 - year China Development Bank bonds changed by 30BP, 20BP, and 30BP respectively.

The 10 - 1 curve flattened [10]. Treasury Bond Yields Presented an "N"-shaped Trend - **January - mid - March**: At the beginning of the year, the central bank suspended Treasury bond trading and reduced open - market investment to stabilize the exchange rate. The tightened capital led to an upward trend in bond market yields. After the Two Sessions, the market adjusted its expectations, and the 10 - year Treasury bond yield reached a high of 1.90% [11][12]. - **Late March - April**: The capital became looser, and the Sino - US tariff "tug - of - war" began. The 10 - year Treasury bond yield dropped to the 1.63% - 1.67% range [16]. - **May - early July**: In early May, the central bank's RRR cut and interest rate cut, along with positive results from tariff negotiations, led to a slight increase in long - end interest - rate bond yields. In June, the central bank's reverse - repurchase operations improved the capital situation, and bond yields fluctuated downward [16]. - **Mid - July - September**: The "anti - involution" policy raised inflation expectations, the equity market strengthened, and the bond market was suppressed. Bond yields rose, but short - end yields were stable, resulting in a "bear steep" pattern [16]. Credit Spreads - Credit Spreads of All Grades First Narrowed and Then Widened - **January - mid - March**: At the beginning of January, interest - rate bonds quickly adjusted upward, and credit spreads were passively narrowed. Before the Two Sessions, the market expected an RRR cut and interest rate cut, and credit spreads widened briefly. After the Two Sessions, credit spreads narrowed rapidly again [17]. - **Late March - April**: The bond market recovered quickly, and credit spreads widened slightly [17]. - **May**: Credit spreads narrowed to the lowest point of the year due to the implementation of monetary policy tools and looser capital [17]. - **June - early July**: Short - end Treasury bond yields declined, and credit spreads first widened slightly and then narrowed [17]. - **Mid - July - September**: The bond market adjusted, and credit spreads widened slightly [17].
