1. Report Industry Investment Rating - No information provided in the report 2. Core Viewpoints of the Report - After the recent adjustment, the allocation value of bonds has started to emerge, and the attractiveness of 30 - year treasury bonds to allocation - type institutions has increased. The market will focus on key events such as the Central Economic Work Conference and the Political Bureau Meeting in December, which may provide new directional guidance. In the short - term, the pattern of a capped and floored bond market is difficult to break, and the yield of 10 - year bonds may remain in the range of 1.75% - 1.85%. If the expectation of interest rate cuts in early next year is strengthened, the bond market is expected to rise [8]. - In the medium - to - long - term, insufficient effective demand is the main challenge in China's economic development. In the new normal stage where the marginal benefits of land finance and debt - driven economic growth decline, the asset - liability tables of residents and enterprises are impacted, and new economic growth drivers are still being cultivated. With the potential impact of trade frictions in the Trump 2.0 era, total demand is unlikely to recover fundamentally in the short term, and deflation is likely to continue. Therefore, the fundamentals are still favorable for bond futures. The coordinated strengthening of monetary and fiscal policies, with monetary policy taking the lead, and a low - interest - rate environment are crucial for policy implementation, making it difficult for bond yields to rise significantly [8]. 3. Summary by Relevant Catalogs 3.1 Main Views - Last week, the performance of treasury bond futures across different maturities was divergent. Ultra - long - term treasury bond futures tumbled, while other maturities weakened slightly, and the long - term trend did not show an obvious inflection point. Negative factors such as the new regulations on public fund sales, year - end policy expectations, central bank bond - buying scale, and regulatory investigations led to concentrated profit - taking and early liquidation, increasing market volatility, especially in the more speculative maturities. The main institutional holders of ultra - long - term treasury bonds had insufficient buying willingness or limited capabilities. On Friday, ultra - long - term bonds stabilized slightly but had weak rebound momentum [4]. - The table shows the closing price, weekly change rate, weekly trading volume, change in weekly trading volume, weekly open interest, and change in weekly open interest of various treasury bond futures contracts [5]. 3.2 Liquidity Tracking - The report presents data on open - market operations (quantity and price), medium - term lending facility (quantity and price), reverse repurchase rate, and various interest rates such as deposit - type pledged repurchase, SHIBOR, and bond - pledged repurchase rates, as well as data on MLF maturity volume, policy rates, and market rates, and also shows the trends of treasury bond yields, treasury bond term spreads, US treasury bond yields, and US treasury bond term spreads [10][12][18][29][34][37] 3.3 Treasury Bond Futures Arbitrage Indicator Tracking - The report provides data on treasury bond futures basis, net basis, implied repo rate (IRR), and implied interest rates for 2 - year, 5 - year, 10 - year, and 30 - year treasury bond futures contracts [44][52][59][65]
