Group 1: Report Overview - The report is a fixed - income report released on July 14, 2025 [1] - Analysts are Liang Weichao and Li Shukai [2] Group 2: Industry Investment Rating - No industry investment rating is provided in the report Group 3: Core Viewpoints - In the second week of July, the bond market entered a consolidation phase. Credit bonds declined less than interest - rate bonds. After the adjustment, the short - term participation window for ultra - long - term bonds has likely passed, and the 3 - 5 - year weak - quality riding strategy may offer better cost - effectiveness. Also, 1 - 2 - year short - duration sinking is a good choice [3][5][30] Group 4: Market Performance Summary Overall Bond Market - In the week from July 7 to July 11, 2025, due to multiple negative factors, the "stock - bond seesaw" effect was in play, with the equity market strengthening and interest - rate bonds weakening. Credit bonds followed the trend of interest - rate bonds but declined less [3][10] Yield Changes of Major Bond Types - For Treasury bonds, the 1Y, 2Y, 3Y, 4Y, and 5Y maturity yields increased by 3.40BP, 4.61BP, 3.67BP, 3.58BP, and 3.63BP respectively. For AAA medium - and short - term notes, the yields changed by - 0.58BP, 1.46BP, 3.34BP, 3.59BP, and 3.87BP respectively; for AA+ medium - and short - term notes, they changed by - 1.58BP, 0.46BP, 1.34BP, 4.59BP, and 2.87BP respectively [10][12] Ultra - long - term Credit Bonds - Ultra - long - term credit bonds were also adjusted. The adjustment of urban investment ultra - long - term bonds was the highest. Only AA+ 10Y medium - term notes performed well with a continued decline in valuation yield. AAA/AA+ 10Y medium - term note yields increased by 2.62BP and decreased by 1.38BP respectively. AAA/AA+ 10Y urban investment yields increased by 3.36BP and 4.36BP respectively, while the 10Y Treasury bond yield only increased by 2.20BP [3][11] Perpetual and Secondary Bonds (Er Yong Bonds) - The market of Er Yong bonds weakened and showed the characteristic of a "volatility amplifier". The decline of those with a maturity of less than 5Y was greater than that of general credit bonds of the same maturity, and the decline of those with a maturity of 7Y and above slightly exceeded that of ultra - long - term credit bonds. The yields of 1 - 5Y, 7Y, and 10Y AAA - bank secondary capital bonds increased by 3.94BP, 5.14BP, 5.79BP, 5.32BP, 5.44BP, 4.35BP, and 4.78BP respectively [4][17] Group 5: Market Feature Analysis Curve Shape - The steepness of the 1 - 2Y for all ratings and 3 - 5Y for low - ratings was the highest, but it was slightly lower compared to the end of May, and the 1 - year segment remained relatively flat [13] Historical Quantiles - The ticket - coupon value of credit bonds remained low. In terms of credit spreads, there may be opportunities for participation in the 3Y - 5Y segment. The yields of 1Y - AAA, 3Y - AAA, etc. were at relatively low levels since 2024, and after a week of adjustment, the short - end 1Y still had no cost - effectiveness, while the protection of 3Y - 5Y was enhanced [15] Active Trading - The trading sentiment of Er Yong bonds was relatively weak. The proportion of low - valuation transactions from July 7 to July 11 was 100.00%, 2.44%, 46.34%, 100.00%, 80.49% respectively, and the average trading durations were 5.90 years, 0.59 years, 2.14 years, 6.25 years, 4.02 years respectively. The trading margin of Er Yong bonds below the valuation was small, generally within 3BP; the discount trading margin was also small, generally within 2BP [19][20][22] Ultra - long - term Credit Bonds - Institutions' willingness to sell ultra - long - term credit bonds increased significantly compared to the previous week. The proportion of discount transactions was 2.44%, 85.37%, 70.73%, 95.12%, 60.98% respectively, and the discount margin was mostly within 3BP. The market's willingness to buy ultra - long - term credit bonds weakened, and the trading focus returned to the 3 - 5 - year riding transactions of low - quality urban investment bonds. Although the market adjusted, institutions' willingness to buy was still strong, with about 45% of the transactions below the valuation having a margin of 4BP or more [5][25][26]
