Report Key Points 1. Report Industry Investment Rating - Not provided in the given content 2. Core View of the Report - On October 27, 2025, the People's Bank of China announced the resumption of open - market treasury bond trading operations. The restart is a policy choice to address market adjustments and liquidity needs and an important signal to promote the marketization of monetary policy. In the short - term, it benefits the bond market, while in the medium - term, it strengthens the coordination between fiscal and monetary policies. The bond market in the fourth quarter is still mainly affected by fundamentals, the implementation time of the fund fee rate new rules, and institutional allocation forces [1][2][5] 3. Summary by Relevant Catalogs I. Main Reasons for Restarting Treasury Bond Trading - **Improved bond market environment and reasonable yield regression**: Since the third quarter, the 10 - year treasury bond yield has risen from 1.61% at the beginning of the year to 1.84% at the end of October. The yield curve has become more stable, creating a better interest - rate environment for the central bank's operations [6] - **Real - world need for coordinated fiscal and monetary policies**: In 2025, with the approval of an additional 500 billion yuan in government bond quotas, the forward - shifted fiscal expenditure rhythm has put pressure on liquidity. Treasury bond trading can smooth liquidity and reduce the market crowding - out effect of government bond issuance [7] - **Operation need to hedge the fourth - quarter liquidity gap**: The total maturity of MLF and repurchase agreements in the fourth quarter is about 3.6 trillion yuan. Buying treasury bonds can provide a flexible and accurate way to inject base - money, and also help stabilize the bank's liability - side [8] - **Preventing unilateral market fluctuations and risk accumulation**: Since July, the "stock - bond seesaw" effect has led to a rapid rise in long - term interest rates. The central bank's restart of treasury bond trading aims to stabilize expectations and prevent one - sided market fluctuations [10] II. Operation Mechanism and Expected Path - The central bank's treasury bond trading mainly focuses on buying short - term bonds, with a small - scale allocation of medium - and long - term bonds. Considering the concentrated maturity of government bonds and medium - and long - term liquidity at the end of the year, if the renewal scale of MLF and reverse repurchase is limited, the central bank may increase the intensity of treasury bond purchases [11] III. Impact of Restarting Treasury Bond Trading on the Bond Market - **Short - term**: It signals a continued loose monetary policy, directly benefiting the bond market. On the day of the announcement, the 10 - year treasury bond yield dropped by about 4BP, and short - term bonds benefited more from improved liquidity [12] - **Medium - term**: It stabilizes market expectations and the yield center, helps the smooth issuance of treasury bonds, and improves the transmission efficiency of macro - policies. The bond market in the fourth quarter is still mainly affected by fundamentals, the implementation time of the fund fee rate new rules, and institutional allocation forces [12]

Report Summary 1. Industry Investment Rating There is no information provided regarding the industry investment rating in the given reports. 2. Core Viewpoints - For the steel industry, in the long - term, steel prices' upward logic remains unchanged under the increasingly loose macro - environment. However, in the short - term, the actual demand for steel is still weak and unlikely to improve substantially. Attention should be paid to the impact of Sino - US talks and overseas macro - environment changes on market sentiment [2]. - For the iron ore market, the price is expected to fluctuate. Although the supply is increasing and the demand is weakening with the decline of iron - making water production, the positive signals from Sino - US economic and trade consultations and the expected interest - rate cut by the Federal Reserve have an impact on the market [5]. - For the black metal sector, the outlook is not pessimistic. It is considered more cost - effective to look for rebound opportunities after price corrections rather than short - selling. The downward momentum of the black metal sector has significantly weakened after nearly four years of decline [10]. - For industrial silicon, the supply pressure persists, and the demand support is weakening. The price is expected to fluctuate with market sentiment in the short - term, and the cost provides some support [14]. - For polysilicon, the supply pressure may be marginally relieved, and the supply - demand pattern may improve. The price is affected by policy expectations and industry news, and attention should be paid to the actual implementation [16]. - For glass, the futures price rebounded due to short - position exits, and the market's bearish sentiment eased. Attention should be paid to macro - policy trends and the operation of production lines in the Shahe area [19]. - For soda ash, the price is expected to continue narrow - range fluctuations in the short - term due to the combination of cost support and high inventory [21]. 3. Summary by Category Steel - **Market Quotes** - The closing price of the rebar main contract was 3133 yuan/ton, up 42 yuan/ton (1.358%) from the previous trading day. The registered warehouse receipts decreased by 1221 tons to 124,540 tons, and the main contract's open interest decreased by 36,350 lots to 1.894 million lots. The Tianjin and Shanghai aggregated prices increased by 30 yuan/ton and 20 yuan/ton respectively [1]. - The closing price of the hot - rolled coil main contract was 3345 yuan/ton, up 40 yuan/ton (1.210%) from the previous trading day. The registered warehouse receipts increased by 3402 tons to 104,773 tons, and the main contract's open interest decreased by 12,738 lots to 1.461 million lots. The Lecong and Shanghai aggregated prices increased by 30 yuan/ton and 20 yuan/ton respectively [1]. - **Strategic Views** - Macroscopically, real - estate investment will shift from "scale expansion" to "quality improvement", and the new construction area is unlikely to increase significantly. Fundamentally, rebar's supply and demand both increased, and inventory continued to decline; the output of hot - rolled coils decreased slightly, demand improved marginally, and inventory reduction accelerated [2]. Iron Ore - **Market Quotes** - The main contract of iron ore (I2601) closed at 804.50 yuan/ton, up 1.51% (+12.00). The open interest decreased by 6094 lots to 542,900 lots, and the weighted open interest was 916,500 lots. The spot price of PB powder at Qingdao Port was 805 yuan/wet ton, with a basis of 52.06 yuan/ton and a basis rate of 6.08% [4]. - **Strategic Views** - The supply of iron ore is increasing, with the overseas shipment volume at a high level. The demand is weakening as the daily average iron - making water production has dropped below 240,000 tons. The port inventory is increasing, and the price is under pressure. However, positive macro - signals may affect the market [5]. Ferrosilicon and Manganese Silicon - **Market Quotes** - On October 29, affected by the market atmosphere and other factors, the price of ferrosilicon and manganese silicon rebounded. The main contract of manganese silicon (SM601) closed up 1.07% at 5852 yuan/ton, and the Tianjin spot price was 5720 yuan/ton, with a basis of 58 yuan/ton. The main contract of ferrosilicon (SF601) closed up 0.54% at 5594 yuan/ton, and the Tianjin spot price was 5650 yuan/ton, with a basis of 56 yuan/ton [8]. - **Strategic Views** - The supply of ferrosilicon and manganese silicon may be restricted in the future. Currently, steel mills are facing difficulties due to high supply and low demand, and there is a risk of "negative feedback". The outlook for the black metal sector is not pessimistic, and it is more cost - effective to look for rebound opportunities. Manganese silicon and ferrosilicon are likely to follow the black metal sector's trend [9][10]. Industrial Silicon and Polysilicon - **Market Quotes** - The main contract of industrial silicon (SI2601) closed at 9170 yuan/ton, up 2.40% (+215).

The price is expected to fluctuate with market sentiment in the short - term, and the cost provides some support [14]. - For polysilicon, the supply pressure may be marginally relieved, and the supply - demand pattern may improve. The price is affected by policy expectations and industry news, and attention should be paid to the actual implementation [16]. Glass and Soda Ash - **Market Quotes** - The glass main contract closed at 1113 yuan/ton on Wednesday, up 1.64% (+18). The inventory of float glass sample enterprises increased by 233.74 million cases (3.64%) to 66.613 million cases.

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - After Powell's hawkish statement, the prices of gold and silver dropped in the short term. The release of the Fed's loose monetary policy expectations still requires a certain period. However, the Fed Chairman has made a statement on balance sheet expansion. This FOMC meeting sent a signal that the December interest rate cut is still uncertain while strengthening the subsequent monetary policy idea of "rate cut + balance sheet expansion." In the loose monetary policy cycle, it is recommended to buy on dips for silver, which will benefit more. The reference operating range for the main contract of Shanghai Gold is 880 - 966 yuan/gram, and that for the main contract of Shanghai Silver is 10937 - 11690 yuan/kilogram [2]. Summary According to Related Catalogs Market Quotes - Shanghai Gold rose 0.69% to 910.92 yuan/gram, and Shanghai Silver rose 0.64% to 11265.00 yuan/kilogram. COMEX Gold was reported at 3949.30 US dollars/ounce, and COMEX Silver was reported at 47.54 US dollars/ounce. The yield of the 10 - year US Treasury bond was reported at 4.08%, and the US dollar index was reported at 99.13 [1]. - The Fed held an FOMC meeting early today. The tone of this meeting was a "hawkish rate cut." Powell's monetary policy statement was hawkish, and he also made a statement on the final balance sheet expansion [1]. Key Focus Directions of the FOMC Meeting - The statement on the subsequent interest rate path was more hawkish than market expectations. Powell stated that "a rate cut in December is not a certainty," and the lack of economic data could be a reason to pause interest rate adjustments [1]. - The discussion on the balance sheet was more dovish than market expectations in the medium term. Although the FOMC decided to end the balance sheet reduction on December 1st, which was later than market expectations, Powell clearly stated that the Fed would expand the balance sheet again. This was his first key statement on balance sheet expansion in this rate - cut cycle [1]. - The voting was more hawkish than market expectations. Fed Governor Milan voted against as expected and supported a 50 - basis - point rate cut. Governors Bowman and Waller did not support aggressive rate cuts. Hawkish voting member Schmidt voted against and supported keeping the interest rate unchanged at this FOMC meeting [2].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - For crude oil, although the geopolitical premium has dissipated and OPEC's production increase is minimal with supply not yet surging, it's not advisable to be overly bearish on oil prices in the short - term. A range - trading strategy of buying low and selling high is maintained, but it's recommended to wait and see for now, waiting for a decline in OPEC exports to confirm the market [3]. - For methanol, the slow import unloading process has slowed port inventory accumulation. The market's main contradiction lies in the unexpected slow unloading due to previous sanctions and recent weather. Although there are potential bullish factors, the overall market structure is weaker than in previous years. It's recommended to wait and see [4]. - For urea, the supply - side device maintenance is over, and the demand - side compound fertilizer production has increased. The enterprise inventory accumulation has slowed down. The spot price has limited downward space, and there are still some positive factors to be released. It's recommended to wait and see or consider long - position opportunities at low prices [7]. - For rubber, the rubber price is strong. Short - term trading with quick entry and exit is recommended, and partial position - building for the hedging strategy of buying RU2601 and selling RU2609 is suggested [13]. - For PVC, the enterprise's comprehensive profit has declined to a low level, but the supply is strong, and the demand is weak. The export expectation is poor, and there is a continuous inventory accumulation pressure. It's recommended to consider short - position opportunities in the medium - term [16]. - For pure benzene and styrene, the BZN spread has room for upward repair. The port inventory of styrene is at a high level, and the price may stop falling periodically [20]. - For polyethylene, the cost - side supports the rebound of crude oil prices. The inventory is being reduced at a high level, and the price may maintain a low - level shock [23]. - For polypropylene, the cost - side supply is in an oversupply pattern, and the overall inventory pressure is high. There is no prominent short - term contradiction [26]. - For PX, the current load is high, and the downstream PTA has many maintenance operations. The inventory is difficult to continuously reduce, and it mainly follows the fluctuation of crude oil [29]. - For PTA, the short - term supply - side maintenance has decreased, and there is a slight inventory accumulation. The demand - side polyester load is expected to remain high, but there is limited room for improvement. The PXN is under pressure [30]. - For ethylene glycol, the domestic supply is high, and the port is expected to accumulate inventory in the fourth quarter. It's recommended to consider short - position opportunities [32]. 3.
