超长信用债行情能持续多久

Report Industry Investment Rating - Not provided in the content Core Views of the Report - The trading volume and liquidity of ultra-long credit bonds have significantly increased in the past two weeks, approaching the historical high in July and August 2024. The market's pursuit of duration for returns is expected to continue this week. The ultra-long credit bond strategy has a certain probability of success but a low odds. Short-duration credit enhancement remains a highly certain strategy [5][8]. - The convertible bond market has a relatively cautious style. In an environment where the equity market is expected to fluctuate, the upward momentum of convertible bonds is limited. However, the current valuation of convertible bonds is not significantly overestimated, and there may be opportunities for capital inflow into high-quality, low-volatility individual bonds. The potential credit risk in June is coming to an end, and if unexpected events occur, the opportunities are considered greater than the risks [5][19]. Summary According to Relevant Catalogs 1 Credit Bond and Convertible Bond Views: How Long Can the Ultra-Long Credit Bond Market Last? - When short-term trading becomes crowded, the market starts to seek returns from duration. This phenomenon is expected to continue this week. The narrowing of short-term spreads has reached an extreme level, forcing liquidity to shift to longer-term bonds of medium-quality issuers. The expansion of fixed-income asset management products and the increasing insurance allocation willingness are expected to bring incremental funds, and the market's offensive on long-term credit bonds is unlikely to end soon [5][8]. - The ultra-long credit bond strategy has execution problems, such as the need for significant interest rate declines or spread compressions to achieve better returns and the lack of stable institutional investors, resulting in rapid loss of liquidity during market corrections. Short-duration credit enhancement is a more certain strategy, and if the liability side is stable, extending duration through secondary perpetual bonds is recommended rather than ultra-long credit bonds [5][13]. - The convertible bond market has a cautious style, with high-rated and low-priced convertible bonds performing better. The three characteristics of the convertible bond market in 2025 remain unchanged. In an environment where the equity market is expected to fluctuate, the upward momentum of convertible bonds is limited, but the long-term allocation logic remains valid, and there may be opportunities for high-quality, low-volatility individual bonds. The potential credit risk in June is ending, and if unexpected events occur, the opportunities are greater than the risks [5][19]. 2 Credit Bond Review: The Spread Compression Market is Becoming More Extreme 2.1 Negative Information Monitoring - There were no bond defaults or overdue payments during the week from June 16 to June 22, 2025. Several companies had their主体评级 or展望下调, and some overseas companies had their ratings downgraded. There were also several significant negative events, such as companies being issued warning letters by regulatory authorities and being listed as dishonest被执行人 [21][22][23]. 2.2 Primary Issuance: Net Financing Continues to Remain at the Billion-Level - From June 16 to June 22, 2025, the primary issuance of credit bonds reached 411.4 billion yuan, with a net financing of 105.4 billion yuan, maintaining a billion-level net financing for three consecutive weeks. Three credit bonds were canceled or postponed for issuance, with a total planned issuance scale of 3.6 billion yuan. The primary issuance costs of medium and high-grade bonds showed a differentiated trend last week [24]. 2.3 Secondary Trading: Liquidity Continues to Strengthen, and Urban Investment Slightly Outperforms Industry - The valuation of credit bonds declined across the board, and the risk-free interest rate curve flattened bullishly. Except for the passive widening of the spreads of low-grade long-term bonds, the spreads of other bonds narrowed or remained unchanged. The term spreads of each grade were mainly flat, but the 3Y - 5Y part of medium and low-grade bonds slightly underperformed. The long-term grade spreads were under pressure to widen. The credit spreads of urban investment bonds in most provinces narrowed by 1 - 3bp last week, with Qinghai having the largest narrowing of 4bp. The industry bonds slightly underperformed urban investment bonds, and the real estate industry's spreads continued to widen by 27bp. The liquidity of credit bonds continued to strengthen, with the turnover rate increasing by 0.27 percentage points to 2.31% [26][30][33]. 3 Convertible Bond Review: The Equity Market Pulled Back, and the Convertible Bond Index Slightly Declined 3.1 Overall Market Performance: The Stock Market Fluctuated and Closed Lower, with Banks and Communications Leading the Gains - From June 16 to June 20, 2025, the Shanghai Composite Index, Shenzhen Component Index, and other major indices mostly closed lower. Only the banking, communications, and electronics sectors rose, while the beauty care, textile and apparel, and pharmaceutical sectors had the largest declines. Most of the leading convertible bonds outperformed their underlying stocks, and the list of popular individual bonds changed little [36]. 3.2 Convertible Bonds Slightly Declined, and the Opportunities Outweighed the Risks - Last week, the convertible bonds slightly declined, with the average daily trading volume significantly decreasing to 61.305 billion yuan. The CSI Convertible Bond Index decreased by 0.17%, the parity center decreased by 1.6% to 94.5 yuan, and the conversion premium rate center increased by 2.2% to 28.7%. High-rated, low-priced, and low-premium convertible bonds performed better, while high-priced, low-rated, and small-cap convertible bonds underperformed. The view on convertible bonds has changed little. In an environment where the equity market is expected to fluctuate, the upward momentum of convertible bonds is limited, but the current valuation of convertible bonds is not significantly overestimated. The long-term allocation logic of the convertible bond market remains valid, and there may be opportunities for capital inflow into high-quality, low-volatility individual bonds. The potential credit risk in June is ending, and if unexpected events occur, the opportunities are greater than the risks [39].
