Group 1: Investment Rating - There is no information about the industry investment rating provided in the report. Group 2: Core Views - Last week, the bond market adjusted continuously. Credit bonds experienced an unexpected "steep decline" with larger drops than interest - rate bonds. Affected by the "anti - involution" sentiment, the equity and commodity markets strengthened, causing the bond market to weaken due to the "see - saw" effect. Tightening liquidity in the second half of the week and strong profit - taking in funds and wealth management also contributed to the decline. The central bank's liquidity support on Friday stabilized the bond market temporarily [2][11]. - The adjustment of ultra - long - term credit bonds exceeded that of interest - rate bonds of the same maturity, with the highest adjustment in perpetual and secondary capital (perpetual and Tier 2, "Perp & T2") ultra - long bonds. The yields of AAA/AA + 10Y medium - term notes, AAA/AA + 10Y urban investment bonds, and AAA - 10Y bank Tier 2 capital bonds all increased significantly [3][12]. - The Perp & T2 bond market weakened and showed a "volatility amplifier" characteristic, with the declines of 3Y and above maturities exceeding those of general credit and ultra - long - term credit bonds of the same maturities. The trading sentiment was weak throughout the week, only easing on Friday [4][17]. - The selling intention of ultra - long - term credit bonds was strong, while the buying intention was weak. High - activity trading was mainly concentrated in 3 - 5Y low - quality urban investment bonds and some short - term real estate and financial bonds with flaws [5][22]. - Public funds continued to reduce their credit bond holdings, especially for bonds with maturities over 5 years. However, the turnover rate of 3 - 5Y Perp & T2 bonds increased significantly, indicating a shift to more liquid varieties. The trading value of credit - market - making ETFs decreased by nearly 4 billion, and the growth rate of the trading value of sci - tech innovation bond ETFs slowed down [5][27]. - In the short term, liquidity is still the key strategy. After the steep decline, 3 - 5Y bank Tier 2 capital bonds present certain investment opportunities, and there are also good opportunities for 1 - 3Y low - quality urban investment bond sinking and riding strategies. It is recommended to wait for better entry points for ultra - long - term bonds [5][27]. Group 3: Summary by Directory 1. Bond Market Adjustment and Performance - From July 21 to July 25, 2025, the yields of 1Y - 5Y treasury bonds increased by 3.5BP, 5.5BP, 7.3BP, 7.9BP, and 7.9BP respectively, while the yields of the same - maturity AAA and AA + medium - term notes increased more significantly [11]. - The yields of 10Y AAA/AA + medium - term notes, AAA/AA + urban investment bonds, and AAA - 10Y bank Tier 2 capital bonds increased by 11.99BP, 9.99BP, 11.14BP, 10.14BP, and 14.47BP respectively, while the 10Y treasury bond yield only increased by 6.72BP [3][12]. 2.

Report Overview - Report Type: Fixed Income Report - Release Date: July 2, 2025 - Analysts: Liang Weichao, Li Shukai 1. Industry Investment Rating No industry investment rating is provided in the report. 2. Core View - The ultra-long-term credit bond market cooled down in the last week of June after two consecutive weeks of heating up, but it is only a temporary adjustment without signs of a market reversal. - In the short term, one can be more optimistic about the opportunities to participate in ultra-long-term credit bonds, especially considering the potential incremental space from the expansion of bond ETF products, which may improve the liquidity of ultra-long-term bonds. - However, the thin coupon protection makes them less resistant to fluctuations, and the vulnerability of the liability side of public fund products should not be ignored. A strategy of quick entry and exit and staying ahead of the news may be a good choice [5][26]. 3. Summary by Directory 3.1 Ultra-long Term Temporarily Cools Down - **Market Performance in the Last Week of June**: The bond market entered a consolidation phase, with interest rates first weakening and then strengthening. Credit bonds performed worse than interest rate bonds, with larger declines. Affected by the "stock-bond seesaw" effect, the short - and medium - term yields of interest rate bonds fluctuated downward, while the long - and ultra - long - term yields adjusted. Credit bonds had different trends from interest rate bonds, with relatively larger adjustment amplitudes [3][10]. - **Performance of Ultra-long-term Credit Bonds**: After two consecutive weeks of rising, ultra-long-term credit bonds adjusted, with the adjustment amplitude even exceeding that of the same - term interest rate bonds. The yields of AAA/AA+ 10Y medium - term notes increased by 2.5BP and decreased by 1.5BP respectively, and the yields of AAA/AA+ 10Y urban investment bonds increased by 3.7BP and 1.7BP respectively, while the 10Y treasury bond yield only increased by 0.7BP [3][10]. - **Curve Morphology**: The steepness of the 1 - 2 year for medium - and high - grade bonds and the 2 - 5 year for low - grade bonds was the highest, but overall it was slightly lower than at the end of May, and the short - end remained flat [12]. - **Absolute Yield and Credit Spread**: The coupon value remains low. In terms of credit spreads, there may be opportunities around the 3 - year mark. After a week of adjustment, the short - term 1 - year still lacks cost - effectiveness, while the protection of the 3 - year has strengthened [14]. - **Performance of Perpetual and Tier 2 Bonds**: The market of perpetual and tier 2 bonds weakened. The decline of those within 5 years was similar to that of the same - term general credit bonds, and the performance of those over 7 years was comparable to that of ultra-long - term credit bonds. The yield of 4 - 10 year AAA - bank tier 2 capital bonds increased by 1.98BP, 0.36BP, 1.38BP, 4.01BP, 3.69BP, 3.85BP, and 2.62BP respectively [4][16]. - **Active Trading of Perpetual and Tier 2 Bonds**: The trading sentiment fluctuated throughout the week, being poor on Tuesday and Wednesday and better on the other days. The proportion of low - valuation transactions and the average trading duration also fluctuated. The trading amplitude of low - valuation and discount transactions was small [18][19][21]. - **Selling and Buying Intentions of Ultra-long-term Credit Bonds**: Institutions' selling intention increased compared with the previous week, but the discount amplitude was mostly within 3BP, not an urgent selling situation. The market's buying intention was not weak, with about 43% of the low - valuation transactions having an amplitude of 4BP or more, indicating the existence of allocation demand [5][22][24].
