油气板块为何持续走强?机构认为存长期逻辑支撑
Huan Qiu Wang· 2026-02-28 02:37
同时,大量资金借道基金抢筹布局油气板块。Wind数据显示,开年以来超80亿元资金净流入油气ETF, 国泰石油ETF、鹏华石油ETF分别获得29.91亿元、15.42亿元净流入。 招商证券认为,抛开短期地缘催化,市场对全球能源需求的持续增长与产能瓶颈存在的明显认知差是油 服行业更为关键的长期成长逻辑。东莞证券进一步分析表示,2025年原油市场因供给阶段性偏松呈累库 状态,2026年随OPEC+强化减产、供给端显著缩量,叠加需求持续复苏,市场进入去库阶段,供需格 局从宽松转向紧平衡。原油需求复苏的持续性与库存去化的确定性形成双重基本面支撑,进一步夯实国 际油价中期偏强运行的基础,为油气企业资本开支落地、油服设备需求释放筑牢核心逻辑。(闻辉) 【环球网财经综合报道】开年以来,受全球宏观周期转向、地缘风险溢价等因素影响,油气板块持续走 强,成为市场关注焦点。年初至今,通源石油涨超170%,洲际油气、招商轮船等多只个股涨幅超 50%,中证油气资源指数整体上涨超33%。 2月27日,油气板块再度上扬,和顺石油涨停,杰瑞股份、胜通能源等个股涨幅超5%。从更长时间维度 看,全球油气板块集体走高,ICE布油价格从去年末的58. ...

1. Report Industry Investment Rating - Not provided in the given content 2. Core Views of the Report - The market is in a clear off - season pattern, with steel prices fluctuating weakly. Glass and soda ash markets also show a weakening trend due to shrinking downstream demand. The double - silicon market in the black sector is in a state of consolidation [1][3] - The glass market has an increasing expectation of production line cold - repair in the Shahe area, which provides some support to the market. The soda ash supply pressure is increasing with new projects, and the downstream consumption is seasonally declining [1] - The fundamentals of silicon manganese have improved slightly, but the inventory pressure is still high. The fundamentals of silicon iron are controllable, and the demand is expected to improve marginally [3] 3. Summary by Related Catalogs Glass and Soda Ash Market Analysis - Glass: The main glass contract fluctuated weakly yesterday, and the trading volume decreased approaching the Spring Festival. The spot price was stable, and downstream enterprises mainly made purchases based on rigid demand [1] - Soda Ash: The main soda ash contract continued to show a weakening trend, and the market sentiment was cautious. In the traditional off - season, the spot market mainly had transactions based on rigid demand [1] Supply - Demand and Logic - Glass: There is a strong expectation of production line cold - repair in the Shahe area, which supports the market. However, the fundamental contradictions have not been effectively resolved, and attention should be paid to cold - repair progress, terminal demand recovery, and coal price impact on costs [1] - Soda Ash: The current production of soda ash is high, and the supply pressure is increasing with new projects. Downstream consumption is seasonally declining, the total inventory of domestic soda ash manufacturers is high, and the de - stocking process is slow. Attention should be paid to new project situations [1] Strategy - Glass: Expected to fluctuate [2] - Soda Ash: Expected to fluctuate weakly [2] Double - Silicon (Silicon Manganese and Silicon Iron) Market Analysis - Silicon Manganese: The silicon manganese futures weakened yesterday, and the spot market was filled with a festive atmosphere. The price of 6517 in the northern market was 5580 - 5680 yuan/ton, and in the southern market was 5700 - 5750 yuan/ton [3] - Silicon Iron: The silicon iron futures fluctuated downward, the market was weak, and the sentiment of cautious waiting and seeing was strong. The ex - factory price of 72 - grade silicon iron in the main production area was 5250 - 5350 yuan/ton, and the price of 75 - grade silicon iron was 5850 - 6000 yuan/ton [3] Supply - Demand and Logic - Silicon Manganese: The fundamentals have improved, and the demand is expected to increase marginally. However, the inventory pressure is still high, and the supply - demand pattern is relatively loose. The South African tariff policy may increase the manganese ore cost, and attention should be paid to cost support and inventory changes [3] - Silicon Iron: The fundamental contradictions are controllable, and enterprises have actively reduced production loads. Considering the resumption of steel mills, the demand is expected to improve marginally. The overall over - capacity suppresses the price increase, and attention should be paid to the de - stocking situation and power price policies in production areas [3] Strategy - Both silicon manganese and silicon iron are expected to fluctuate [4]

1. Report Industry Investment Rating - No information provided in the report 2. Core Viewpoints - The main contract price of rebar oscillated downward with a daily decline of 0.65%, and the volume and open interest increased. Currently, both the supply and demand sides of rebar have weakened, the fundamental weakness remains unchanged, and steel prices in the off - season continue to be under pressure. The relative positive factor is cost support. It is expected to continue the trend of oscillating to find the bottom, and attention should be paid to the inventory accumulation during the holiday [5]. - The main contract price of hot - rolled coil oscillated weakly with a daily decline of 0.43%, and the volume and open interest decreased. At present, the supply of hot - rolled coil is at a high level, while the demand has weakened, and the fundamentals are weak. The price of hot - rolled coil will still be under pressure and oscillate at a low level. Attention should be paid to the demand performance and beware of the pressure caused by the intensification of the contradiction of weakening demand [5]. - The main contract price of iron ore declined weakly with a daily decline of 1.23%, and the volume and open interest decreased. Currently, the demand for iron ore is weakly stable, while the supply pressure still exists. The fundamentals of iron ore continue to weaken, and the inventory is rising at a high level. Under the dominance of the real - world logic, the price of iron ore is under pressure and runs weakly. Attention should be paid to the shipping situation of miners [5]. 3. Summary of Each Section 3.1 Industry Dynamics - In January 2026, the global manufacturing PMI was 51%, up 1.5 percentage points from the previous month, ending the continuous 10 - month running trend below 50%. By region, the manufacturing PMI in Africa decreased to 49.6%, that in Europe rose to 50%, that in Asia slightly decreased to 51%, and that in the Americas rose to 51.8% [7]. - In January 2026, the average monthly working hours of China's main construction machinery products were 72.5 hours, a year - on - year increase of 23.9% and a month - on - month decrease of 5.19%, among which excavators were 62.8 hours. The average monthly start - up rate of main construction machinery products was 48.1%, a year - on - year decrease of 2.63 percentage points and a month - on - month decrease of 3.63 percentage points, among which excavators were 48.6% [8]. - Anglo American raised its iron ore production target for 2026. The total iron ore output in the fourth quarter of 2025 was 15.1 million tons, a year - on - year increase of 6% and a quarter - on - quarter increase of 5%. The total iron ore sales volume in the fourth quarter was 16.17 million tons, basically flat year - on - year and a quarter - on - quarter increase of 12%. The annual iron ore output in 2025 was 60.8 million tons, a slight year - on - year decrease of 2%, and the cumulative annual iron ore sales volume was 61.54 million tons, a year - on - year increase of 1%. The annual iron ore production guidance target for 2026 was raised to 55 - 59 million tons (previously 54 - 58 million tons). Among them, the output of the Kumba mine is 31 - 33 million tons, and that of the Minas - Rio mine is 24 - 26 million tons [9]. 3.2 Spot Market - The spot prices of rebar in Shanghai, Tianjin and the national average were 3,190, 3,160 and 3,306 respectively; the spot prices of hot - rolled coil in Shanghai, Tianjin and the national average were 3,250, 3,150 and 3,284 respectively; the price of Tangshan billet was 2,930; the price of Zhangjiagang heavy scrap was 2,160; the coil - rebar price difference was 60, and the rebar - scrap price difference was 1,030. The price changes of rebar, hot - rolled coil, Tangshan billet and Zhangjiagang heavy scrap were 0, - 10, 0, 0 respectively [10]. - The price of PB powder at Shandong ports was 756 with a change of - 9; the price of Tangshan iron concentrate was 767 with a change of - 1; the sea freight from Australia and Brazil was 8.34 and 23.57 respectively with changes of - 0.01 and - 0.39; the SGX swap price was 100.90 with a change of - 1.60; the iron ore price index (61% FE, CFR) was 100.30 with a change of - 1.95 [10]. 3.3 Futures Market - The closing price of the rebar futures active contract was 3,077, with a decline of 0.65%, the highest price was 3,111, the lowest price was 3,074, the trading volume was 723,307, the volume difference was 41,902, the open interest was 1,915,253, and the open interest difference was 67,582 [14]. - The closing price of the hot - rolled coil futures active contract was 3,251, with a decline of 0.43%, the highest price was 3,270, the lowest price was 3,250, the trading volume was 276,669, the volume difference was - 7,206, the open interest was 1,484,610, and the open interest difference was - 10,036 [14]. - The closing price of the iron ore futures active contract was 760.5, with a decline of 1.23%, the highest price was 772.0, the lowest price was 760.0, the trading volume was 216,259, the volume difference was - 115,477, the open interest was 514,745, and the open interest difference was - 10,368 [14]. 3.4 Related Charts - The report presents charts of steel and iron ore inventories, including weekly changes and total inventories of rebar and hot - rolled coil, as well as iron ore inventories in 45 ports, 247 steel mills, and domestic mines [16][22]. - It also shows charts of steel mill production, such as the blast furnace start - up rate and capacity utilization of 247 sample steel mills, the start - up rate of 94 independent electric furnace steel mills, the proportion of profitable steel mills among 247 steel mills, and the profitability of 94 independent electric arc - furnace steel mills [31][33]. 3.5 Market Outlook - For rebar, both supply and demand have seasonally weakened, and inventory has continued to accumulate. The weekly output of rebar decreased by 81,500 tons month - on - month, and the supply has shrunk, but the inventory level is significantly higher than the same lunar period last year, and the pressure relief is limited. The demand for rebar continues to be seasonally weak, and the weekly apparent demand and high - frequency daily transactions have both shrunk significantly. Considering that there is no improvement in downstream industries, the weak demand pattern is difficult to change. The relative positive factor is the policy expectation after the holiday. It is expected to continue the trend of oscillating to find the bottom, and attention should be paid to the inventory accumulation during the holiday [39]. - For hot - rolled coil, the supply - demand pattern has changed little, and the inventory has increased again. The production of plate mills has stabilized, the weekly output of hot - rolled coil decreased by 50 tons month - on - month, and the overall level remains relatively high, and the inventory level is high, so the supply pressure remains. The demand for hot - rolled coil has weakened, the weekly apparent demand decreased by 58,700 tons month - on - month, and the high - frequency daily transactions have continued to run at a low level. The relative positive factor is that the output of downstream cold - rolled products remains at a high level, which supports the demand for hot - rolled coil. However, attention should be paid to the potential pressure from the intensification of demand - weakening contradictions, and attention should be paid to the demand performance [39]. - For iron ore, the supply - demand pattern remains weak, and the inventory continues to rise. The production of steel mills has stabilized, and the terminal consumption of iron ore has slightly rebounded. The daily average pig iron output and the daily consumption of imported ore of sample steel mills have both increased this week. However, considering that the profitability of steel mills has not improved and the contradictions in the steel market have accumulated, the demand improvement is limited. At the same time, the arrival volume at domestic ports is weakly stable, but the shipping volume of miners continues to increase, and the overseas supply of iron ore has stabilized and rebounded. Even though the domestic supply of iron ore has seasonally shrunk, the supply pressure remains under the high - inventory situation. The price of iron ore is under pressure and runs weakly under the dominance of the real - world logic, and attention should be paid to the shipping situation of miners [40].
