1. Report Industry Investment Rating - No information provided in the document. 2. Core Views of the Report - This week, fuel oil prices rose significantly, with the price center gradually reaching a two - month high. For high - sulfur fuel oil, market transactions improved slightly, the premium increased, Middle East shipments remained high, but Russian exports continued to decline. Due to recent attacks and sanctions, nearly one - third of Russian refinery capacity was offline, so supply factors still supported high - sulfur fuel oil. If Russian exports continue to face obstacles, high - sulfur fuel oil valuations may continue to rise. For low - sulfur fuel oil, there is no obvious supply gap in the Asia - Pacific region, and spot shipments are normal. The August Singapore bunker sales data was good, providing some support on the demand side. On the domestic market, the quota issue has been fully priced in by the market, but inventory continued to accumulate in the Zhoushan area, and there were still warehouse receipts on the futures market. In the short term, the price may be relatively weaker than that of high - sulfur fuel oil. - Valuation: FU is estimated to be in the range of 2700 - 3000, and LU is estimated to be in the range of 3400 - 3650. - Strategies: 1) Unilateral: FU will continue to be strong in the short term, and LU will mainly follow the upward trend. 2) Inter - period: FU and LU will maintain the current structure. 3) Inter - variety: FU cracking will fluctuate at a high level; the LU - FU spread may still contract slightly in the short term.

Group 1 - Fuel oil futures main contract showed weak fluctuations, closing at 2784.00 yuan with a decline of 1.21% [1] - Demand remains sluggish in the Asian fuel oil market, with Northeast Asian refineries experiencing slower sales [1] - Taiwan's Formosa Petrochemical's 76,000 barrels per day residue fluid catalytic cracking unit is under maintenance until the end of October, impacting supply [1] Group 2 - High sulfur fuel oil prices are influenced by ongoing sanctions and recent attacks on Russian refineries, leading to a significant increase in high sulfur exports to India [2] - Singapore's fuel oil inventory has decreased by 4.2%, while ARA and Fujairah inventories have also seen reductions [2] - The EU is expected to introduce the 19th round of sanctions against Russia in the coming weeks, which will be a key focus for high sulfur fuel oil [2]

Report Overview - Report Title: Fuel Oil and Low-Sulfur Fuel Oil Weekly Report - Report Date: September 21, 2025 - Analyst: Liang Kefang from Guotai Junan Futures Research Institute [1] 1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints - This week, the prices of fuel oil and low-sulfur fuel oil still fluctuated, but the amplitude significantly narrowed. For high-sulfur fuel oil, Middle East exports remained high, and the spot market transaction premium in the Asia-Pacific region continued to be below 0. There is a possibility of shipments from Northwest Europe to Asia, making it difficult for the Asia-Pacific low-sulfur market price to improve. For low-sulfur fuel oil, the previous strength of the Asia-Pacific low-sulfur price has basically disappeared. The shutdown of downstream facilities in Nigeria may continue to provide support in the future, but due to high port inventories and the price difference between the domestic and foreign markets, the domestic LU futures price is unlikely to turn strongly bullish. - The estimated value range is 2650 - 2900 for FU and 3300 - 3500 for LU. - Strategies include: 1) Unilateral: The bottom support of FU is emerging, while LU is weakening marginally. 2) Inter - period: FU and LU will maintain their current structures. 3) Inter - commodity: The cracking spread of FU will fluctuate at a high level; the LU - FU spread may still contract slightly in the short term.

Report Overview - Report Title: Fuel Oil and Low-Sulfur Fuel Oil Weekly Report [1] - Author: Liang Kefang from Guotai Junan Futures Research Institute [1] - Date: September 14, 2025 [1] 1. Report Industry Investment Rating - Not provided in the content 2. Core Views - This week, the prices of fuel oil and low-sulfur fuel oil fluctuated widely with increased volatility, and the price center generally moved downward. For high-sulfur fuel oil, Middle East exports remained high, and the window transaction premium was weak, indicating weak spot market transactions. The domestic inventory was replenished in the early stage, and the near-month contracts were continuously suppressed. The domestic and international prices are expected to have limited improvement in the short term. However, there is a possibility that the US and Europe may increase sanctions on Russia, which will bring significant uncertainty to the high-sulfur supply and support prices. For low-sulfur fuel oil, in addition to the continuous supply recovery in Japan, Brazil's exports to the Asia-Pacific region also increased since the end of August. Coupled with some European arbitrage supplies in transit, the Asia-Pacific spot prices are expected to remain weak. The amount of the new quota is still one of the core factors affecting LU valuation. If the quota increases significantly year-on-year, given the high inventory in Zhoushan, the pattern of loose or even surplus supply will have an obvious negative impact on the LU market. Since the issuance time and specific scale of the new quota are still highly variable, continuous observation is needed [4]. - Valuation: FU is estimated to be in the range of 2650 - 2900, and LU in the range of 3300 - 3500 [4]. - Strategies: 1) Unilateral: FU is expected to oscillate strongly in the short term, while LU is relatively weak. 2) Inter-period: FU and LU will maintain their current structures. 3) Inter-variety: The cracking spread of FU will oscillate at a high level; the LU - FU spread may rebound [4]. 3.

In terms of spreads, the domestic FU and LU were relatively stronger than the overseas market, and the premium increased [80]. - **Logic**: This week, the spot prices at home and abroad generally declined. Due to the high inventory in the Singapore market, the overseas spot prices were generally weak. In the domestic market, after the delivery, the inventory on the futures market was digested to some extent, which supported the prices of FU and LU and made them relatively stronger than the overseas spot prices. The premium of FU and LU relative to the Singapore market increased [80]. - **Spot and Futures Market Spreads**: Data on the 380 and 0.5% spot and futures market spreads between domestic and Singapore fuel oil from 2021 - 2025 are presented [84][85][88][89][90]. - **FU and LU Position and Volume Changes**: Data on the trading volume and open interest of fuel oil main contracts, low - sulfur fuel oil continuous and first - month contracts from 2020 - 2025 are presented [93][95][98][100][101]. - **FU and LU Warehouse Receipt Quantity Changes**: Data on the changes in the quantity of FU and LU warehouse receipts from 2020 - 2025 are presented [104][105].

Group 1: Report Industry Investment Rating - No information provided Group 2: Core Views of the Report - Asian near - term high - sulfur supply and inventory remain at a high level. Ukrainian bombings of Russian refineries have entered a continuous stage, affecting some refinery capacities and favoring high - sulfur to some extent. Mexican high - sulfur exports are continuously declining, and the supply pressure of high - sulfur in the third quarter is slightly less than expected. On the demand side, the decline in high - sulfur cracking and the increase in China's fuel oil consumption tax deduction are beneficial to the growth of high - sulfur feedstock demand, while the seasonal power generation demand for high - sulfur is gradually decreasing. [7] - Low - sulfur fuel oil spot premiums continue to decline. The increase in spot window sellers and near - term supply growth have hit low - sulfur spot prices. Low - sulfur supply continues to recover, and there is no specific driver for downstream demand. Attention should be paid to the near - term low - sulfur export logistics changes and the adjustment and issuance rhythm of low - sulfur quotas in the Chinese market. [7] Group 3: Summary by Relevant Catalogs First Part: Relevant Data - On August 13, 2025, the FU main contract was 2730, down 40 from the previous day; the LU main contract was 3463, down 39 from the previous day. The FU main contract position was 145,000 lots, down 4,000 lots from the previous day; the LU main contract position was 51,000 lots, unchanged from the previous day. The FU warehouse receipt was 92,710 tons, unchanged from the previous day; the LU warehouse receipt was 21,050 tons, unchanged from the previous day. [3] - The FU9 - 1 spread was - 42, down 12 from the previous day; the LU10 - 11 spread was 12, up 5 from the previous day. The LU - FU main contract spread was 733, up 1 from the previous day. The FU09 - foreign market 08 spread was - 15.8, up 0.2 from the previous day; the LU10 - foreign market 09 spread was 7.6, up 4.8 from the previous day. [3] Second Part: Market Research and Judgment - **Market Overview**: A piece of important news is that on Wednesday, the Russian authorities said that the debris of a destroyed drone caused a small fire at the Slaviansk refinery in the Krasnodar region of Russia, and the fire was quickly extinguished. [6] - **Market Judgment**: As mentioned in the core views, the supply and demand situation of high - sulfur and low - sulfur fuel oil is analyzed, and the changes in spreads in the Singapore paper market are also mentioned, such as the high - sulfur Sep/Oct month - spread dropping from 4.8 to 3.3 US dollars/ton, and the low - sulfur Sep/Oct month - spread dropping from 3.5 to 2.0 US dollars/ton. [7] Third Part: Relevant Attachments - There are six graphs including Singapore high - sulfur spot premium, Singapore low - sulfur spot premium, Singapore high - and low - sulfur spread, Singapore LSFO - GO, high - sulfur fuel oil cracking, and low - sulfur fuel oil cracking, with data sources from Galaxy Futures and Reuters. [9]

Group 1: Report Industry Investment Rating - No relevant information provided Group 2: Core Viewpoints of the Report - The supply shortage of 0.5% sulfur marine fuel oil may last until July, and the weakening crack spread may prompt some Asian refineries to increase raw material procurement for this fuel oil grade [3]. - The high - sulfur fuel oil has a spot premium over the futures, and the Singapore fuel oil inventory decreased in the week of June 4, which is bullish. The price is below the 20 - day line and the 20 - day line is flat, which is neutral. The high - sulfur main position changed from short to long, while the low - sulfur main position increased short positions [3]. - Overnight crude oil rose and then fell, which is expected to drive fuel oil to open lower. The EIA short - term report lowered next year's US crude oil production but predicted a shift from supply - demand balance to oversupply this year, so the fuel oil is under pressure, and it will fluctuate weakly in the short term. The FU2509 will operate in the range of 2900 - 2960, and the LU2508 will operate in the range of 3530 - 3600 [3]. - The market is driven by the uncertain supply - side production cuts and neutral demand [4]. Group 3: Summary by Directory 1. Daily Prompt - The high - sulfur fuel oil's Singapore price is 435.05 dollars/ton with a basis of 245 yuan/ton, and the low - sulfur fuel oil's Singapore price is 499.5 dollars/ton with a basis of 115 yuan/ton. The high - sulfur fuel oil's main position changed from short to long, and the low - sulfur fuel oil's main position increased short positions. The expected operating ranges for FU2509 and LU2508 are given [3]. - The futures prices of FU and LU increased by 0.68% and 0.57% respectively, and the bases decreased by 5.02% and 26.15% respectively [5]. - The spot prices of various fuel oils in different regions increased, with the increase range from 0.20% to 1.98% [6]. 2. Multi - Short Concerns - Bullish factors: OPEC+ additional production cuts continue (but implementation needs to be tracked), and China's import quotas are released [4]. - Bearish factors: The optimism on the demand side remains to be verified, and there is a possibility of relaxing sanctions on Russia [4]. 3. Fundamental Data - The supply of 0.5% sulfur marine fuel oil may remain tight until July due to the closed East - West arbitrage window, and the weakening crack spread may lead to increased raw material procurement [3]. 4. Inventory Data - The Singapore fuel oil inventory on June 4 was 2140.9 million barrels, a decrease of 61 million barrels compared to the previous period [3][8]. 5. Spread Data - There is information about the historical spread between high - sulfur and low - sulfur fuel oil futures [14].
