1. Report Industry Investment Rating No information provided in the content. 2. Core Viewpoints of the Report - The over - rise of bond interest rates at the beginning of the year has been digested, but the bond market repair may not come quickly and is likely to gradually repair in fluctuations. The report suggests a dumbbell - shaped operation, i.e., short - term credit/certificates of deposit + long - term interest rates, and conduct high - selling and low - buying band operations on long - term interest rate positions. The 10 - year treasury bonds with yields above 1.8% still have allocation value, and the long - term bond interest rates may decline more smoothly in the second half of the fourth quarter, with the interest rates expected to hit new lows this year [6][20]. 3. Summary According to Related Content Bond Market Interest Rate Trends This Week - This week, bond interest rates rose again. The yields of the 10 - year and 30 - year treasury bond active bonds 250011.IB and 2500002.IB increased by 2.5bps and 5.5bps respectively compared with last week, reaching 1.79% and 2.08%. The 10 - year treasury bond active bond once exceeded the key point of 1.8%. The interest rates of certificates of deposit and credit also increased. The 1 - year AAA certificate of deposit interest rate rose 1.1bps to 1.68%, and the 3 - year and 5 - year AAA - secondary capital bond interest rates soared 10.0bps and 9.7bps to 2.02% and 2.14% [1][9]. Reasons for the Bond Market's Volatility This Year - In the first three quarters of this year, the overall bond market fluctuated and adjusted, making it difficult to obtain stable investment returns. Although affected by factors such as fundamental changes, large - bank bond selling, rising commodity prices due to anti - involution policies since the third quarter, the continuous strengthening of the stock market, and the recent public - fund fee - rate new regulations, the major background was that the over - rise of interest rates at the beginning of the year over - exhausted the subsequent space to some extent [1][9]. Evidence of Interest Rate Over - rise at the Beginning of the Year - From the perspective of capital return rate, interest rates are still in a downward trend. Since 2010, the enterprise return rate has been in a downward trend, with EBIT/total assets dropping from 10.4% in 2010 to 4.4% this year, with an average annual decline of about 40bps. The corresponding interest rates, especially the loan interest rates, have also been in a downward trend, with an average annual decline of 30bps since 2011. The loan interest rates are highly consistent with the bond interest rates. From October last year to January this year, the 10 - year treasury bond interest rate dropped by 56bps in total, resulting in a decline in the relative cost - effectiveness of the bond market and forming the continuous fluctuation pattern of the bond market this year [2][10]. Evidence that the Interest Rate Over - rise Has Been Digested - **Trend perspective**: If the 10 - year treasury bond interest rate drops by about 30bps annually, the bond market was basically over - rising in the first half of this year. By September this year, if the year - on - year interest rate decline is 30bps, the 10 - year treasury bond interest rate should be around 1.8%, which is consistent with the current level, indicating that the over - rise part has basically been digested [3][11]. - **IRS implied interest - rate cut expectation perspective**: Currently, the IRS no longer contains interest - rate cut expectations, and the expectation of monetary easing has basically been digested. Since the beginning of 2025, the IRS - FR007 spread once widened to about 50bp, but since August 5th, the FR007 - IRS (MA20) spread has been continuously positive, indicating that the market does not imply expectations of looser funds or interest - rate cuts in the next year [3][13]. - **Term spread perspective**: At the beginning of the year, the over - rise of long - term bonds and the tightening of funds led to a significant inversion of the yield curve. As of August 29th, the spread between the 1 - year certificate of deposit and R007 (20D MA) expanded to 16.2bps, significantly higher than the 2024 average of 6.2bps. The spread between the 10 - year treasury bond and the 1 - year AAA certificate of deposit reached 17.3bps, which is very close to the 2024 average of 17.5bps. With the normalization of the curve, the short - end loose liquidity is expected to protect long - term bonds from short to long [4][16]. - **Fundamental and explainable perspective**: By fitting and explaining the 10 - year treasury bond interest rate with GDP growth rate, the average of CPI and PPI, the capital price R007, and the time - trend term, it is found that although the interest rate dropped below one standard deviation of the fitting value in the first half of this year, indicating a certain degree of over - rise in the bond market, it returned to the one - standard - deviation fluctuation range after the interest - rate adjustment in the third quarter, indicating that the interest rate has entered the range explainable by fundamentals [5][17]. Factors Affecting the Bond Market in the Short Term - The stock market trend is uncertain. Although the stock - bond correlation has weakened, a rapid rise in the stock market may still impact the bond market when non - banks still hold a certain position. Public - fund fee - rate new regulations and quarter - end capital impacts may also affect the bond market in the short term. Additionally, the bond market is often seasonally weak in September and October [5][19][20].
