Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core Viewpoints of the Report - In May, the credit bond market had an independent performance. By the end of the month, the valuation yields of urban investment bonds with implicit ratings from 1 - 5 years reached historical lows, and credit spreads also hit lows. Only the 5 - year variety still had compression space. At the end of the month, there was a slight bond - market shock, with a 2 - 3bp retracement in credit bond yields and spreads [1]. - Short - duration spreads hit new lows, while term spreads and grade spreads still have room. The yields of 1 - year varieties in May continued to decline, breaking the low in June 2024. There is still room for compression in grade spreads and term spreads [2]. - Currently, the coupon advantage of credit bonds remains, but the valuation fluctuation risk has started to increase. The main reasons for the stronger performance of credit bonds than interest - rate bonds in May were the decline in the central funds rate and the increased demand for credit bond allocation due to deposit transfer. However, overseas uncertainties and institutional behavior changes at the end of the month and quarter have a growing impact on the market [3]. - In the future, short - duration spreads of various implicit ratings have reached historical lows. Without new expectations, the probability of further decline in the short - term is low. The main capital gain space may come from the compression of grade spreads and term spreads. At the same time, the valuation fluctuation risk of credit bonds is accumulating, and medium - and long - term risks cannot be ignored [3][5]. - Strategically, investors are advised to adopt a duration strategy. Consider 3 - 4 - year credit bonds for riding returns, and also consider extending the duration of high - grade credit bonds to 6 - 7 years. The annualized riding return of AAA - grade bonds is about 2.6% [5]. Group 3: Summary by Related Catalogs Credit Bond Market Performance in May - The valuation yields of 1 - 5 - year urban investment bonds with various implicit ratings reached historical lows, and credit spreads also hit lows. Only the 5 - year variety still had compression space. At the end of the month, there was a slight bond - market shock, with a 2 - 3bp retracement in credit bond yields and spreads [1]. - The yields of 1 - year varieties in May continued to decline, breaking the low in June 2024. The 3 - year AA +, AA, and AA(2) implicit ratings had grade spreads of 7bp, 16bp, and 27bp compared to AAA, with 5 - 10bp compression space compared to historical lows. The historical quantiles of term spreads of 3 - year and 5 - year varieties compared to 1 - year varieties of the same rating were still in the 10% - 20% range [2]. Reasons for Market Performance and Future Outlook - The stronger performance of credit bonds than interest - rate bonds in May was due to the decline in the central funds rate and increased credit bond allocation demand from deposit transfer. But overseas uncertainties and institutional behavior changes at the end of the month and quarter had a growing impact. At the end of May, fund redemptions caused significant bond - market fluctuations [3]. - Short - duration spreads have reached historical lows. Without new expectations, the probability of further decline in the short - term is low. The main capital gain space may come from the compression of grade spreads and term spreads. The valuation fluctuation risk of credit bonds is accumulating, and medium - and long - term risks cannot be ignored [3][5]. Investment Strategy - Adopt a duration strategy. Consider 3 - 4 - year credit bonds for more riding returns. Also, consider extending the duration of high - grade credit bonds to 6 - 7 years. Based on the end - of - month yield curve, the annualized riding return of AAA - grade bonds is about 2.6% [5].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - Since 2021, the logic of the "asset shortage" in the bond market is not applicable this year. Instead, the bond market presents a "liability shortage." The liability gap and structure are the main lines of bond market trading this year [2][5][12]. - The bond market is unlikely to rise trend - wise. Only continuous negative carry can drive the trend - wise correction of long - term interest rates. The probability of a tightening of capital prices in the second quarter is not high, and the market interest rate is expected to fluctuate in the range of 1.5% - 1.6% [2][8][22]. - The bond market has no obvious odds recently. A 10bp positive carry can boost the inter - bank bond market leverage ratio by about 0.1 - 0.2 percentage points. The current positive carry amplitude is insufficient, restricting the market's enthusiasm for leveraging [2][8][30]. - It is recommended to allocate when the 10 - year Treasury bond yield is above 1.65% and the 30 - year Treasury bond yield is above 1.9%. Institutions with stable liabilities can appropriately focus on the coupon opportunities of credit bonds with a term of more than 3 years [2][8][34]. 3. Summary by Related Catalogs 3.1 From "Asset Shortage" to "Liability Shortage", Bond Market Volatility - Before 2024, the "asset shortage" was the main line of the bond market. Due to the downward pressure on the real estate industry and the establishment of the regulatory red line for local implicit debt, credit expansion was constrained. Since this year, with the adjustment of the social financing structure and the relative stability of credit, the "asset shortage" is no longer the main contradiction. The supply of government bonds has increased, and the social financing growth rate has rebounded to 8.7% in April [5][12]. - While the asset supply has increased, the bond market faces a "liability shortage." The central bank's attitude is not the only source of liability pressure. Currently, the market style is more trading - oriented, lacking stable - liability configuration forces. Insurance's premium income growth has declined significantly this year, and its trading attribute has increased; wealth management is undergoing rectification, reducing the allocation of less - liquid credit bonds; public funds have a strong wait - and - see sentiment [8][19]. 3.2 Difficulty in Trend - wise Market, Focus on Curve Trading Opportunities - The bond market is difficult to rise trend - wise. In a relatively stable fundamental situation, only continuous negative carry can drive the trend - wise correction of long - term interest rates. The current fundamental situation is relatively stable, but the real interest rate is high, and there is still uncertainty in the fundamental recovery. The probability of a tightening of capital prices in the second quarter is not high [8][22]. - The bond market has no obvious odds recently. Although the bond market has returned to the positive carry range, the amplitude is insufficient, restricting the market's enthusiasm for leveraging. A 10bp increase in carry can increase the inter - bank bond market leverage ratio by 0.14 and 0.21 percentage points respectively. Since May, the average monthly inter - bank bond market leverage ratio has increased by about 0.2 percentage points compared with April [8][30]. - Before the bond market shows sufficient odds, it is difficult to have a trend - wise market. It is expected that the 10 - year Treasury bond yield will fluctuate around 1.6% - 1.7%. It is recommended to capture trading opportunities along the yield curve. Institutions with stable liabilities can focus on the coupon opportunities of credit bonds with a term of more than 3 years [8][34].
