Report Summary 1. Industry Investment Rating - Not provided in the report. 2. Core Views High-Sulfur Fuel Oil - **Core View**: Neutral with a slight positive bias. Recent drivers are on the supply side. OPEC+ is expected to increase production by about 550,000 barrels per day. Chevron has regained the license to produce oil in Venezuela, and Venezuelan crude oil shipments to Asia have decreased. As the deadline for the US-Russia agreement approaches and Russian refineries are attacked, the high-sulfur price is relatively supported. Attention should be paid to recent high-sulfur spot procurement and digestion, as well as tariff sanctions and crude oil quotas [4]. - **Spread**: Neutral with a slight negative bias. Affected by tariff sanctions, as the US-Russia negotiation deadline approaches and Russian oil exports are blocked, the supply risk premium rises. The high-sulfur spread fluctuates at a high level of around -$3 per ton, weaker than last week [4]. - **Price Difference**: Neutral with a slight negative bias. The decline in international crude oil prices drags down the fuel oil price [4]. - **Supply**: Negative. The global total shipment is expected to be loose. Western arbitrage cargoes are arriving in Singapore successively, and the arrivals in Singapore are high, with still large inventory pressure [4]. - **Demand**: Neutral with a slight negative bias. The power generation demand is gradually weakening [4]. - **Inventory**: Neutral. Singapore's fuel oil has started to destock but remains at a high level [4]. Low-Sulfur Fuel Oil - **Core View**: Neutral with a slight negative bias. OPEC+ continues to increase production, and the crude oil price weakens. In the short term, the low-sulfur fuel oil price is expected to fluctuate. The arrivals of low-sulfur fuel oil in Singapore in August are at a high level, and Kuwait's low-sulfur shipments are stable, with no obvious increase in low-sulfur supply. The low-sulfur market in China has sufficient supply, and the demand is dominated by rigid demand. The domestic marine fuel market is in a stalemate. In July, CNOOC's low-sulfur quota was exhausted, and the production scheduling expectations of Sinopec and PetroChina are weak. Attention should be paid to the recent adjustment or issuance of low-sulfur quotas [5]. - **Spread**: Neutral with a slight negative bias. Affected by tariff sanctions, as the US-Russia negotiation deadline approaches and Russian oil exports are blocked, the supply risk premium rises. The low-sulfur spread fluctuates slightly in the range of $8 - $9 per ton, slightly down from last week [5]. - **Price Difference**: Negative. The spot price difference of low-sulfur fuel oil is weak, and in the short term, it is under pressure. The price difference between high and low-sulfur fuel oils narrows [5]. - **Supply**: Neutral. The departures from Brazil in July and August are low. The early return of Dangote RFCC leads to a reduced expectation of low-sulfur supply. Continued attention should be paid to the arrivals [5]. - **Demand**: Neutral with a slight positive bias. The summer power generation demand for low-sulfur fuel oil is weakening, and the marine fuel demand is stable and improving, but due to sufficient supply, the bunkering profit is average [5]. - **Inventory**: Neutral. Singapore's fuel oil inventory remains at a high level [5]. 3. Summary by Relevant Catalogs Core Logic - **Russia**: In July, the offline refining capacity was adjusted upwards. From July to August, it reached the annual maintenance low, providing strong support for high-sulfur exports in the next three months. The offline primary refining capacity in August is expected to drop to 3.74 million tons (a month-on-month decrease of 260,000 tons). As of August 14, 2025, Russia's weekly high-sulfur exports are about 650,000 tons. The EU passed the 18th round of sanctions against Russia in July 2025, including a reduction in the Russian oil export price from $60 to $47.6 per barrel and a ban on new transactions of the Nord Stream 1 and 2 gas pipelines. The US imposed an additional 25% tariff on India, raising the tax rate to 50%. According to EA analysis, India may reduce its Russian crude oil imports to less than 1 million barrels per day [9]. - **Latin America**: As of August 10, 2025, the high-sulfur fuel oil exports from Latin America are about 270,000 tons, a month-on-month decrease. In July 2025, the crude oil processing volume of Mexican refineries increased slightly. On July 25, Chevron regained the license, and the crude oil flowing from Venezuela to Asia is expected to decrease. On August 7, 2025, a new coking unit of the Tula refinery started operation, with a residue processing capacity of 100,000 barrels per day. After the commissioning, the crude oil processing volume of Tula increased from the previous 150,000 tons per day to 170,000 barrels per day [11]. - **Middle East**: In July 2025, the high-sulfur fuel oil exports from the Middle East were 4.36 million tons, at a historical low for the same period. Saudi Arabia's high-sulfur fuel oil exports increased significantly to 210,000 tons in July (+34.5%), mainly shipped to Singapore, Malaysia, and South Asia. As of August 10, 2025, the floating storage of fuel oil in the Middle East increased slightly to 1.17 million tons (+140,000 tons). The power generation demand in July was not high. The tension in the Israel-Iran conflict has subsided, and there are no new variables in the high-sulfur fuel oil exports from the Middle East. The large-scale maintenance of Middle East refineries has ended, and the maintenance capacity of refineries in July was between 12.6 million and 18.9 million tons [14]. - **Singapore**: As of August 10, 2025, the floating storage of high-sulfur fuel oil in the Pan-Singapore region is about 1.18 million tons (a month-on-month increase of 60,000 tons), at a high level. This week, the arrivals of fuel oil in Singapore are 675,000 tons (a month-on-month increase of 100,000 tons), mainly from Russia and the Middle East. The departures are 100,000 tons (a month-on-month increase of 60,000 tons), mainly flowing to China and Southeast Asia [19][22]. - **China**: Shandong Province is piloting an increase in the tax refund amount for some independent refineries' fuel oil, and the expected increase in the fuel oil consumption tax deduction ratio is 25%, leading to a decline in the feedstock cost of fuel oil. Under the tax reform pilot, China's high-sulfur fuel oil imports rebounded from the low in May. The imports in June were about 1.05 million tons, and in July about 700,000 tons. As of August 10, 2025, the imports of high-sulfur fuel oil in China are about 390,000 tons (a month-on-month decrease of 140,000 tons) [37]. Inventory - As of August 15, 2025, the inventory in Singapore is 3.88 million tons (a month-on-month decrease of 260,000 tons), in the US 3.1 million tons (a month-on-month decrease of 10,000 tons), in Fujairah 1.16 million tons (a month-on-month decrease of 360,000 tons), in ARA 1.03 million tons (stable), and in Zhoushan 1.18 million tons (a decrease of 60,000 tons). As of August 14, 2025, the total fuel oil warehouse receipts are 80,710 tons (Yangshan Petroleum -5,000 tons, Sinochem Xingzhong -7,000 tons), and the total low-sulfur fuel oil warehouse receipts are 16,080 tons (Yangshan Petroleum -4,970 tons) [92][94][97].

Report Summary 1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints - Last week, international crude oil trended downward, and fuel oil prices mostly fluctuated lower. High - sulfur fuel oil closed at 2,709 yuan/ton, down 2.06% for the week, while low - sulfur fuel oil closed at 3,484 yuan/ton, up 0.87% for the week [5]. - Ample supply continues to suppress the fundamental of the low - sulfur fuel oil market. Traders expect a surge in Western arbitrage cargoes to boost inventories in Singapore. Due to the short - term inventory increase expectation, the spot spread of 0.5% sulfur marine fuel has fallen to the lowest discount level in more than four months. Despite the continuous closure of the arbitrage window for compliant 0.5% sulfur marine fuel from Northwest Europe to Singapore, low - sulfur blending components from the market west of Suez still flow in continuously. Meanwhile, weak downstream demand will continue to suppress the market fundamentals in the coming weeks [5]. - For high - sulfur fuel oil, although the immediate supply is sufficient and the seasonal public demand weakens, which continues to suppress the Asian high - sulfur fuel oil market, the premium of downstream high - sulfur fuel oil in Singapore is boosted by stable demand and moderate shipping schedules. Additionally, the expected supply reduction from September may support the market [5]. - Next week, international crude oil prices may have room to fluctuate higher, and Singapore fuel oil prices will continue to fluctuate narrowly following the market. Operationally, trade high - sulfur fuel oil in the 2,650 - 2,800 range and low - sulfur fuel oil in the 3,400 - 3,550 range in the short term [5]. 3.

Report Industry Investment Rating - High-sulfur fuel oil: Neutral [4] - Low-sulfur fuel oil: Bearish [5] Core Views High-sulfur fuel oil - OPEC+ is expected to increase production by about 550,000 barrels per day. Chevron has regained the license to produce oil in Venezuela, and the crude oil logistics from Venezuela to Asia has decreased. Currently, the high-sulfur supply in Asia is sufficient and inventories are accumulating. The bunker fuel加注 volume in Fujairah has weakened month-on-month. As the deadline for the agreement set by the US on Russia approaches, the high-sulfur price is relatively supported. Attention should be paid to the recent high-sulfur spot procurement and digestion, tariff sanctions, and crude oil quotas [4]. Low-sulfur fuel oil - OPEC+ continues to increase production, and the crude oil price is weakening. In the short term, the low-sulfur fuel oil price is expected to fluctuate. The low-sulfur arrivals in Singapore reached a high in August, and the low-sulfur shipments from Kuwait are stable, with no obvious increase in low-sulfur supply. The low-sulfur market in China has sufficient supply, and demand is mainly driven by rigid needs. The domestic bunker fuel market is at a standstill. In July, CNOOC's low-sulfur quota was exhausted, and the production scheduling expectations of Sinopec and PetroChina are weak. Attention should be paid to the recent adjustment or issuance of low-sulfur quotas [5]. Summary by Category High-sulfur fuel oil - **裂差**: Under the influence of tariff sanctions, as the negotiation deadline between the US and Russia approaches, Russian oil exports are受阻, and the supply risk premium has increased. The high-sulfur crack spread is at a high level and has strengthened compared to last week [4]. - **价差**: The decline in international crude oil prices has dragged down the fuel oil price [4]. - **供应**: The global total shipments are expected to be loose, and the arrivals in Singapore are relatively high [4]. - **需求**: The power generation demand weakened after reaching its peak in August [4]. - **库存**: Inventories at the ports of Singapore and Zhoushan have significantly increased [4]. Low-sulfur fuel oil - **裂差**: Under the influence of tariff sanctions, as the negotiation deadline between the US and Russia approaches, Russian oil exports are受阻, and the supply risk premium has increased. The low-sulfur crack spread fluctuates slightly within the range of $10 - $12 per ton and has rebounded slightly compared to last week [5]. - **价差**: The spot spread of low-sulfur fuel oil is weak and under short-term pressure, and the spread between high and low-sulfur fuels has narrowed [5]. - **供应**: The global low-sulfur supply has not changed much. Dangote Refinery cancelled its maintenance in June, and the increase in Brazilian exports has remained stable. The low-sulfur exports from Al-Zour have recovered with the end of technical problem maintenance, and recent outbound shipments have remained at a high level. In July, CNOOC's low-sulfur quota was exhausted, and the production scheduling expectations of Sinopec and PetroChina are weak [5]. - **需求**: The low-sulfur power generation demand in summer has weakened, the bunker fuel demand remains stable, and downstream buyers take delivery based on rigid needs [5]. - **库存**: The arrivals of low-sulfur fuel oil in China have continued to rise to a historical high [5].

Report Summary 1. Report Industry Investment Rating No information provided. 2. Core View of the Report - Last week, international crude oil trended downward, and fuel oil prices mainly oscillated lower. High - sulfur fuel oil closed at 2776 yuan/ton, down 4.80% for the week, and low - sulfur fuel oil closed at 3464 yuan/ton, down 4.97% for the week [5]. - Due to sufficient supply and competitive spot cargo quotes, the spot premium of 0.5% sulfur marine fuel oil fell to a more than four - month low. With Western arbitrage cargoes arriving in Singapore, the regional inventory in Singapore will significantly accumulate in August. More low - sulfur blending components are expected to flow into the Asian market from the markets west of Suez in August [5]. - For high - sulfur fuel oil, although the immediate supply in the Singapore area remains sufficient, stable downstream bunker demand provides some support. However, traders are still worried that the decline in seasonal power generation demand from utilities will suppress the market fundamentals. With many uncertainties, crude oil prices will continue to oscillate, and fuel oil prices are still under pressure. Operationally, trade high - sulfur fuel oil in the 2740 - 2900 range and low - sulfur fuel oil in the 3400 - 3550 range [5]. 3. Summary by Directory 3.1 Week - ly View - International crude oil declined last week, fuel oil prices oscillated lower. High - sulfur fuel oil dropped 4.80% to 2776 yuan/ton, and low - sulfur fuel oil dropped 4.97% to 3464 yuan/ton [5]. - Low - sulfur fuel oil spot premium hit a four - plus - month low. Singapore's inventory will accumulate in August, and more low - sulfur components will flow into Asia [5]. - High - sulfur fuel oil has stable bunker demand but faces pressure from fading power generation demand. Crude oil price uncertainty keeps fuel oil prices under pressure. Suggested trading ranges are given [5]. 3.2 Futures and Spot Prices - **Futures Prices**: The FU main contract's previous value was 2918, the current value is 2823, down 95 or 3.26%.
