1. Report Industry Investment Rating - No relevant information provided 2. Core Viewpoints of the Report - The iron ore 2601 contract is expected to fluctuate in the short - and medium - term, and show a slightly weaker fluctuation in the intraday trading. Attention should be paid to the pressure at the MA20 line. The demand has certain resilience, and the ore price will fluctuate at a high level [1]. - The supply and demand of iron ore have both increased. The steel mill production is stable, and the terminal consumption of ore has rebounded from a high level, providing support for the ore price. However, the steel mill profits are shrinking, and there are continuous production - restriction disturbances. The supply of overseas ore has increased significantly, and domestic ore production is recovering. The fundamentals of iron ore have not improved substantially, and the high - valued ore price has limited upward driving force. The subsequent trend is expected to continue to fluctuate at a high level, and the performance of finished steel should be monitored [2]. 3. Summary by Relevant Catalogs 3.1 Variety Viewpoint Reference - For the iron ore 2601 contract, the short - term view is "fluctuation", the medium - term view is "fluctuation", and the intraday view is "slightly weaker fluctuation". The reference view is to pay attention to the pressure at the MA20 line, and the core logic is that the demand has certain resilience and the ore price fluctuates at a high level [1]. 3.2 Market Driving Logic - The supply and demand of iron ore have both increased. The terminal consumption of ore has rebounded from a high level, but the steel mill profits are shrinking and there are production - restriction disturbances. Overseas ore supply has increased significantly, and domestic ore production is recovering. The fundamentals have not improved substantially, and the high - valued ore price has limited upward driving force. The subsequent trend will continue to fluctuate at a high level, and the performance of finished steel should be noted [2]

Report Summary 1. Investment Rating No investment rating for the industry is provided in the report. 2. Core View The report concludes that from a fundamental perspective, there has been an increase in both shipments and arrivals this period. Shipments from Australia have steadily recovered, while there are significant increases in shipments from Brazil and non-mainstream mines, leading to increased overall supply pressure. On the demand side, the current pig iron output is 240.7 million tons, showing a week-on-week increase of 0.34 million tons, and it is expected to continue a slight upward trend in the next period. Overall demand remains at a high level but fluctuates. The production restrictions in the north before September 3 will have a phased impact on demand, so attention should be paid to relevant production restriction policies. In summary, after the basis of iron ore narrows, there is clearly insufficient upward momentum. In the short term, the spot and futures prices may continue to fluctuate and adjust, and the basis may strengthen. It is expected that the 01 contract will fluctuate between 90 - 100 US dollars [9]. 3. Summary by Directory 3.1 Fundamentals and Conclusions - **Price**: Last week, the prices of mainstream iron ore spot products showed slight fluctuations. For example, the price of Carajás fines increased by 6, while PB fines decreased by 6. As of August 15, the Platts 62% index closed at $101.8, up $0.3 week-on-week, equivalent to approximately 851 yuan after currency conversion. The optimal deliverable product is Newman fines, with a current price of around 767 yuan/ton, and the converted warehouse receipt (factory warehouse) is around 792 yuan/ton. The 09 iron ore contract is at a discount to the spot [6]. - **Inventory**: The iron ore inventory at 47 ports in China has increased week-on-week but is lower than the same period last year. As of now, the total inventory at 47 ports is 143.8157 million tons, an increase of 1.14 million tons week-on-week, a decrease of 12.29 million tons compared to the beginning of the year, and 12.71 million tons lower than the same period last year. Considering the unloading end, the arrivals are expected to decline; from the demand side, the pig iron output has slightly increased, and the average daily port clearance volume has increased. It is predicted that the overall unloading and warehousing volume at 47 ports in the next period may be lower than the outbound volume, and the port inventory may slightly decrease [6]. - **Supply** - **Shipments**: The total global iron ore shipments this period are 34.066 million tons, an increase of 3.595 million tons week-on-week. The total shipments from 19 ports in Australia and Brazil are 26.697 million tons, an increase of 2.419 million tons week-on-week. Australia's shipments are 16.042 million tons, an increase of 0.238 million tons week-on-week, of which the volume shipped to China is 13.475 million tons, a decrease of 0.181 million tons week-on-week. Brazil's shipments are 10.655 million tons, an increase of 2.181 million tons week-on-week [7]. - **Arrivals**: From August 11 - 17, 2025, the total arrivals at 47 ports in China are 27.031 million tons, an increase of 1.315 million tons week-on-week; the total arrivals at 45 ports are 24.766 million tons, an increase of 0.947 million tons week-on-week; and the total arrivals at six northern ports are 12.525 million tons, an increase of 0.495 million tons week-on-week [7]. - **Demand**: The average daily pig iron output of 247 sample steel mills has increased this period, reaching 240.66 million tons per day, an increase of 0.34 million tons per day compared to last week, 0.54 million tons per day higher than the beginning of the year, and 11.89 million tons per day higher than the same period last year. One new blast furnace is under maintenance this period, located in the Northeast region, due to weakening downstream demand for finished products. It is expected to last until the end of the month. Blast furnaces that resumed production in the previous cycle have gradually reached full production this week, so the pig iron output has slightly increased. According to the blast furnace start - up and shutdown plans, the pig iron output may continue to increase slightly in the next period. As of August 15, in the long - process spot market, the cash - inclusive cost of long - process rebar in East China is 3134.5 yuan, with a point - to - point profit of around 138 yuan, and the long - process cash - inclusive profit of hot - rolled coils is around 225.5 yuan. In the electric furnace market, the flat - rate electricity cost of electric furnaces in East China (according to Fubao) is around 3368 yuan, and the off - peak electricity cost is around 3240 yuan. The flat - rate electricity profit of rebar in East China is around - 138 yuan, and the off - peak electricity profit is around - 10 yuan [8]. 3.2 Data Sorting - **Iron Ore Warehouse Receipt Price**: Details of the chemical indicators, quality premiums, brand premiums, spot prices, and converted factory warehouse receipt prices of various iron ore varieties are provided.

Report Overview - Report Type: Iron Ore Daily Review [1] - Date: June 25, 2025 [2] - Research Team: Black Metal Research Team [3] 1. Investment Rating - No investment rating information is provided in the report. 2. Core Viewpoints - In the short term, steel mills are still in the process of production cuts, but due to their weak willingness to control losses and production, and the support of downstream demand under the effect of export rush, the production cut pace is expected to be tortuous, and the iron ore price will generally show a volatile and weak state with short - term support at the bottom [12]. - In the medium and long term, the real estate investment is still declining at a rate of about 10%, and the growth rate of infrastructure investment is difficult to make up for the real estate gap. After the 90 - day suspension period in the United States, the uncertainty of exports will gradually appear in the data. The high steel production may not be sustainable. Coupled with the gradual release of the incremental supply of iron ore after the Xipo project is put into production, the chain of "terminal demand decline - steel enterprise profit narrowing - steel enterprise production cut - iron ore price trend decline" may appear in the second half of the year [13]. 3. Summary by Directory 3.1 Market Review - **Futures Market**: On June 24, the main 2509 contract of iron ore futures fluctuated weakly. After a sharp decline at the opening, it oscillated, and then fell again in the afternoon, closing at 703.0 yuan/ton, down 0.42%. Other steel futures contracts also showed varying degrees of decline [7]. - **Spot Market**: On June 24, the main iron ore outer - disk quotes were flat compared with the previous trading day, and the prices of main - grade iron ore at Qingdao Port were lowered by 0 - 5 yuan/ton compared with the previous trading day [9]. - **Technical Analysis**: The daily KDJ indicator of the iron ore 2509 contract showed a divergent trend, with the J - value turning down and the K - value and D - value continuing to rise; the red column of the daily MACD indicator of the iron ore 2509 contract has been expanding for two consecutive trading days [9]. 3.2 Market Outlook - **Short - term**: Although steel mills are in the process of production cuts, due to good profit levels, the production cut pace is tortuous. Last week, the daily average pig iron output rebounded, and the blast furnace capacity utilization rate and operating rate both increased, indicating strong support on the demand side of iron ore. The supply of iron ore is expected to be loose until mid - July [12]. - **Medium - and Long - term**: Real estate investment is declining, and the uncertainty of steel exports will increase after the 90 - day suspension period in the United States. The high steel production may not be sustainable, and the supply of iron ore will increase after the Xipo project is put into production, which may lead to a decline in iron ore prices [13]. 3.3 Industry News - In May 2025, China's coal imports continued to decline both year - on - year and month - on - month. The import volume dropped to 3604.0 million tons, a month - on - month decrease of 178.5 million tons (4.7%) and a year - on - year decrease of 777.6 million tons (17.7%) [14]. - On June 24, local time, the Israeli military claimed to have detected Iran launching missiles at Israel after the cease - fire agreement took effect, and the Israeli defense minister ordered a strong response. Iran denied the claim [14]. 3.4 Data Overview - The report provides a series of data charts, including the prices of main iron ore varieties at Qingdao Port, the price differences between high - grade, low - grade ores and PB powder, the basis between iron ore spot and the September contract, the shipping volume of Brazilian and Australian iron ore, the arrival volume at 45 ports, etc. [19][23][30]

Report Information - Report Type: Iron Ore Daily Review [1] - Date: June 18, 2025 [2] - Research Team: Black Metal Research Team [3] - Researchers: Zhai Hepan, Nie Jiayi, Feng Zeren [3] 1. Report Industry Investment Rating - Not provided in the report 2. Core Viewpoints - The iron ore market is currently in a situation where supply is becoming more abundant and demand is gradually declining, leading to a weakening trend in ore prices. However, due to the relatively good profitability of steel enterprises, the decline in ore prices may be limited in the short term. In the long term, factors such as the continuous decline in real estate investment and potential uncertainties in steel exports may lead to a downward trend in ore prices [10][11] 3. Summary by Directory 3.1 Market Review and Future Outlook - **Market Review**: On June 17, the main iron ore futures contract 2509 showed a weak and volatile trend, closing at 699.0 yuan/ton, down 0.07%. The main iron ore outer - market quotes decreased by 0.5 - 1 US dollars/ton compared with the previous trading day, and the prices of iron ore with main grades at Qingdao Port showed mixed changes, with a fluctuation range of - 5 to + 5 yuan/ton. Technically, the KDJ indicator of the iron ore 2509 contract showed a divergent trend, and the MACD red column began to narrow [7][9] - **Future Outlook**: In the short term, although the iron ore market is weak, there is still some support below due to the relatively good profitability of steel enterprises. In the long term, factors such as the continuous decline in real estate investment, potential uncertainties in steel exports after the 90 - day suspension period in the US, and the release of increased iron ore supply from the Xipo project may lead to a downward trend in ore prices [10][11] 3.2 Industry News - From June 9 to June 15, the total transaction (signing) area of newly - built commercial housing in 10 key cities was 1.6088 million square meters, a month - on - month increase of 24% and a year - on - year decrease of 3.6%. From June 17 to 21, a new round of heavy rainfall will occur from Southwest China to the Huanghuai and Jianghuai regions. On June 17, relevant departments issued multiple meteorological warnings and the Ministry of Transport launched a level - 4 defense response to heavy rainfall [12] 3.3 Data Overview - The report presents multiple data charts related to the iron ore market, including the prices of main iron ore varieties at Qingdao Port, the price differences between different grades of iron ore, the shipping volume of iron ore from Brazil and Australia, the arrival volume at 45 ports, and other data [16][18][24]
