Core Viewpoint - The bond market is experiencing significant adjustments, with fund managers expressing concerns about pressure and actively shortening duration and adjusting structures to cope with future steepening of the yield curve [1][2][4]. Group 1: Market Conditions - The bond market faced a severe downturn on August 18, with 10-year and 30-year government bond yields rising by 5 basis points and 6 basis points respectively, closing at 1.79% and 2.06% [1]. - Despite a brief recovery earlier in August, the bond market has been under pressure again due to increased market risk appetite, with the 10-year government bond yield surpassing the high point from July [1][4]. Group 2: Fund Manager Insights - Fund managers are facing redemption pressures, particularly in bond funds, but they believe that the bond market does not have a foundation for a long-term decline, as the 10-year government bond yield of 1.8% reflects current expectations [2][9]. - The performance of pure bond funds has been poor, with average returns for medium to long-term pure bond funds at -0.19% and short bond funds at -0.03% [7]. Group 3: Factors Influencing the Bond Market - The bond market's adjustment is driven more by expectations rather than changes in the funding environment, with a potential shift from deflation to a mild inflation scenario impacting long-term bonds negatively [4][5]. - There is a notable lack of configuration funds from small and medium-sized banks, with a significant decrease in bond investment balances reported [4]. Group 4: Future Outlook and Strategies - Fund managers are adjusting their strategies to focus on shorter durations and are maintaining a neutral to high duration stance while reducing exposure to long-term rates [9]. - The overall sentiment is that while the bond market may not see significant positive catalysts in the short term, it remains within a range of support and resistance, with a cautious approach recommended [9]. Group 5: Recommendations for Investors - Fund managers suggest that credit bond funds may yield over 2% in the coming year, and investors should consider gradually increasing their exposure to these funds [11]. - For individual investors, maintaining a long-term perspective and potentially increasing allocations during market adjustments is advised, while also considering a balanced portfolio with some equity exposure [11].

Industry Investment Rating - No information provided Core Viewpoints - Since July, the long - end bond yields have risen and the yield curve has steepened. The adjustment of long - end rates is mainly due to the correction of deflation expectations, the rise of the stock market, and the improvement of market risk appetite. It is expected that when the 10 - year Treasury bond adjusts to around 1.80%, the bond market odds will be prominent, institutional trading willingness will increase, and the bond market may stabilize [8][17][29] Summary by Directory 1. Reasons for Recent Interest Rate Increases - The short - end interest rates have not changed significantly due to the continuous low - level of capital interest rates and the loose capital situation. Since April, the capital interest rate DR007 has continued to decline, and the inter - bank certificate of deposit rate has also shown a downward trend. Since August, the 1 - year inter - bank certificate of deposit rate has been running in the low - level range of 1.60 - 1.65% [11] - The "anti - involution" policy has led to an increase in inflation expectations and raised the long - end interest rate center. After the relevant policies were introduced in July, industries such as automobiles, photovoltaics, etc. started "anti - involution" actions, which increased inflation expectations [14] - The continuous rise of the stock market has suppressed the bond market. Since July, the stock market has accelerated its rise, the market risk preference has increased, and the long - end bond market has been suppressed [16] 2. Assessment of Interest Rate Adjustment - From the perspective of stock - bond correlation, the negative correlation between the Shanghai Composite Index and the 10Y Treasury bond yield is still strong. Since April this year, the negative correlation has been strong, and it is expected to remain so in the future, with the rise of equities continuing to suppress the bond market [19] - From the perspective of credit comparison, after the recent adjustment, as of August 15, the 10Y and 30Y Treasury bond yields have returned to a reasonable range compared with credit. The 10Y Treasury bond yield is 1.75%, slightly higher than the actual income of the first - home mortgage, and the 30Y Treasury bond yield is 2.05%, higher than the actual income of the second - home mortgage [20] - From the perspective of term spreads, the long - end interest rates still have room to rise. In previous similar adjustment periods, the term spreads increased by 25BP and 27BP respectively. In this round, from April 29 to August 15, the 10Y - 1Y term spread has increased by 21BP, and there is still 5BP of upward space [24]
