债市短评：债市可能与股市逐步脱钩

1. Report Industry Investment Rating - The report is bullish on the bond market in the short - term, expecting the 10Y Treasury yield to return to around 1.65% in the next six months and the 5Y national and regional bank secondary capital bonds to reach below 1.9% [1][2] 2. Core View of the Report - The bond market may gradually decouple from the stock market as the long - term bond holdings of securities firms' proprietary trading and bond funds decline significantly. The recent bond market correction is due to the systematic active reduction of duration by bond funds and securities firms' proprietary trading, not related to the economic fundamentals [1] - Since 2010, only stock bull markets driven by fundamentals have led to bond bear markets, while those driven by funds have not. The current stock market rally may be driven by funds and has a weak relationship with fundamentals [1] - The diversion of funds from the bond market by the stock market is limited. The growth of the bond investment of bank proprietary trading is significant, and the scale growth of wealth management products is less affected by the stock market [1] - There are multiple reasons to be bullish on the bond market in the short - term, including continuous central bank easing, increasing economic downward pressure, possible restart of central bank's Treasury bond purchases, continuous decline in bank liability costs, and the passing of the peak of government bond net issuance [1][2] 3. Summary by Relevant Catalogs 3.1 Bond - Stock Relationship - From July 1 to August 22, 2025, in the secondary trading of inter - bank market interest - rate bonds, securities firms' proprietary trading net - sold 479 billion yuan, including 114.6 billion yuan of bonds with a remaining maturity of over 20 years; public funds (excluding money - market funds) net - sold 436 billion yuan of interest - rate bonds, including 60.5 billion yuan of those with a maturity of over 20 years. As the long - term bonds held by bond funds and securities firms' proprietary trading are transferred to insurance funds and other allocation players, the impact of the stock market on the bond market will weaken [1] - Since 2010, there have been three major stock market bull markets: the 14Q4 - 15Q1 bull market was driven by funds, resulting in a bull market for both stocks and bonds; the 2017 and 2020 - 2021 bull markets were driven by economic recovery, leading to a bear market in bonds. The 2024 "924" stock market rally led to a rapid adjustment in the bond market, but the bond market stabilized quickly after the stock market peaked on October 8 [1] 3.2 Diversion of Funds - As of the end of July 2025, the bond - holding scale of bank proprietary trading reached 99 trillion yuan, accounting for 52% of the total scale of China's bond market. In the first seven months of 2025, the net issuance of Chinese bonds totaled 14.3 trillion yuan, and the bond investment balance of the banking industry increased by 9.6 trillion yuan, accounting for 67.5% [1] - The diversion of funds from the bond market by the stock market is mainly reflected in the possible moderate increase in the stock investment ratio and decrease in the bond investment ratio of flexible allocation funds, annuities, and insurance funds during a stock bull market, but the actual diversion scale is limited. The scale growth of wealth management products is due to the substitution of deposits and is less affected by the stock market [1] 3.3 Reasons for Bullish on the Bond Market - Central bank's continuous easing: Since 25Q2, the DR001 and DR007 interest rates have dropped significantly, indicating a shift from "de - facto interest rate hike" in 25Q1 to "de - facto interest rate cut". It is expected that the capital interest rate will remain low and have low volatility in the next six months [1] - Increasing economic downward pressure: Consumption subsidies may overdraw the demand for household appliances, the consumption growth rate started to decline in July, the real estate market remains sluggish, and the investment growth rate has dropped significantly, so the economic downward pressure may increase significantly in the second half of the year [1] - Possible restart of central bank's Treasury bond purchases: Considering the recent significant rebound in Treasury bond yields, indicating an oversupply of Treasury bonds, the central bank may restart Treasury bond purchases when the 10Y Treasury yield reaches above 1.8% [1][2] - Decrease in bank liability costs: As the deposit interest rates have been significantly reduced in the past few years, the bank liability cost rate is expected to decline quarter - by - quarter. The 10Y Treasury bonds have certain allocation value for most bank proprietary trading, and the weak credit demand may prompt banks to increase bond investment [1][2] - Passing of the peak of government bond net issuance: As of August 22, the net issuance of government bonds since the beginning of the year has reached 10.4 trillion yuan, accounting for 75% of the annual plan, and the net issuance scale in Q4 is expected to be small [2]
