Core Viewpoints of the Report - The bond market is still in a long - position channel in the second half of 2025. The exchange - rate constraint has weakened significantly. With the coordinated efforts of monetary and fiscal policies, liquidity is expected to remain loose. The decline in institutional liability costs is expected to bring incremental funds to the bond market. The weak economic fundamentals suggest a low possibility of short - term fiscal policy intensification, and inflation improvement may occur in the fourth quarter [1]. - The allocation value of 10 - year treasury bonds is prominent. They are suitable for asset allocation, with better market depth and breadth. Compared with medium - short - term and ultra - long - term treasury bonds, they have advantages in duration and risk - return ratio [1]. - The Shanghai Stock Exchange 10 - year Treasury Bond Index can connect treasury bond futures and spot markets. It has high return stability, low volatility, and low risk [1]. - The Guotai Shanghai Stock Exchange 10 - year Treasury Bond ETF has investment value, including low fees, good tracking effect, scarcity, diverse trading mechanisms, and excellent investment performance [1]. 3. Summary by Directory 3.1 Bond Market Review and Future Outlook 3.1.1 Review of the Interest - Rate Bond Market in the First Half of 2025 - The yield curve of treasury bonds first experienced a "bear - flat" and then a "bull - flat" trend. In Q1 2025, long - term bonds corrected due to tightened funds and bank liability pressure. In April 2025, the bond market quickly turned bullish. From May to June 2025, after the yield declined to a low level, the focus was on exploring spreads [7]. - The bond market in 2025 has three new features: the central bank's policy rate is the bottom of the money market; short - term bonds perform weakly, and long - term bonds are difficult to trade; the overall fundamentals are stable, but tariff pulses have a large impact [13]. 3.1.2 The Bond Market Remains in a Long - Position Channel in the Second Half of 2025 - Liquidity is expected to remain loose in July. The decline in institutional liability costs will bring incremental funds to the bond market, including the reset of bank time deposits and the potential reduction of insurance product preset interest rates [17][21]. - The weak economic fundamentals suggest a low possibility of short - term fiscal policy intensification. Inflation may bottom out in the third quarter, and improvement may occur in the fourth quarter. The bond market is still in a long - position window, but the odds are limited, and the current trading logic may continue to focus on exploring spreads [1][29]. 3.1.3 The Allocation Value of 10 - Year Treasury Bonds is Prominent - 10 - year treasury bonds are suitable for asset allocation as their pricing is based on fundamentals, and their pricing logic is different from that of stocks and commodities [37]. - The 10 - year treasury bond market has better depth and breadth, with large scale, wide participation, high trading activity, and a good futures - spot linkage effect. Its market position may be further consolidated in the future [45]. - Compared with medium - short - term treasury bonds, 10 - year treasury bonds have duration offensive advantages and a coupon safety cushion. Compared with ultra - long - term treasury bonds, they have a better risk - return ratio [49][57]. 3.2 Shanghai Stock Exchange 10 - Year Treasury Bond Index: A Bridge Connecting Treasury Bond Futures and Spot Markets 3.2.1 Index Compilation Scheme - The index was launched on March 7, 2013.
