Core Viewpoint - The recent Central Financial Committee meeting emphasized the need to regulate low-price disorderly competition among enterprises, guide companies to improve product quality, and promote the orderly exit of outdated production capacity. This policy signal has led to a noticeable recovery in the sentiment of the bulk commodity market, with some investors anticipating market benefits similar to those from the supply-side structural reforms of 2016 [3][4]. Policy Impact Analysis - Different periods may have varying policy focuses, necessitating an in-depth analysis of the core impact range of policies. Attention should be directed towards industries with severe overcapacity, widespread losses, high proportions of outdated capacity, and strong policy constraints [4]. - Industries such as polysilicon, industrial silicon, and PVC currently exhibit persistently low profit levels, aligning with the main objectives of policy regulation. The sustainability of profit improvement in these industries hinges on the enforcement strength of policies and the effectiveness of actual capacity clearance [4][5]. Historical Context - The aluminum industry serves as an example where strong policy constraints successfully led to sustained profit improvements during the last capacity reduction phase. Historical experience indicates that there is a certain lag between policy issuance and market rebound, ultimately relying on strict enforcement to achieve profit redistribution within the industry chain [4]. Current Industry Status - Leading companies in industries like polysilicon are beginning to formulate capacity optimization plans. However, due to differences in company nature, interest conflicts, and market constraints, the realization of substantial capacity clearance in the industry will require more time for validation [5]. Profit and Capacity Overview - A summary of key indicators for various bulk commodities, including profit levels, capacity concentration, and the nature of enterprises, has been compiled for reference [6]. - For example, the profit margins and capacity concentration for several commodities are as follows: - PVC: -13% profit margin, 40% capacity concentration, state-owned enterprises [9] - Polysilicon: -13.5% profit margin, 82.23% capacity concentration, private enterprises [10] - Urea: 20% profit margin, 28% capacity concentration, state-owned enterprises [9] - Copper products show varying profit margins, with electrolytic copper at 0.31% and lithium battery copper foil at 26.07% [10].

Market Overview - The A-share market is currently lacking catalysts, leading to increased volatility pressure. The downward space for large-cap stocks is relatively limited under the support of the Central Huijin Investment. Short-term focus is recommended on defensive sectors such as banks and low-volatility dividend stocks [2][4] - New consumption and innovative pharmaceuticals are facing higher adjustment risks in the short term, suggesting that investors should wait for risk release before seeking more cost-effective investment opportunities [2][4] Stock Market Factors - The large-cap value style remains dominant in the market, while the volatility of both large and small-cap styles has decreased. The volatility of value and growth styles is at a near-year low [6][8] - The excess return dispersion of industry indices is at a near-year low, with a decrease in the proportion of rising constituent stocks and an increase in industry rotation speed [6][8] - Market activity remains low, with the market volatility at a near-year low and a slight increase in turnover rate [7][8] Commodity Market Factors - In the commodity market, the trend strength of black and precious metals has decreased, while the trend strength of agricultural products has increased. The basis momentum of precious metals and non-ferrous metals has rapidly declined [19][22] - The volatility of energy and precious metals has slightly increased, while other sectors remain at near-year low volatility levels. Liquidity performance is mixed across sectors, with the energy sector at a near-year high in liquidity [19][22] Options Market Factors - The implied volatility levels of the SSE 50 and CSI 1000 show no significant trend, with the implied volatility of CSI 1000 remaining at historically low levels. The skewness of put options for CSI 1000 has increased, indicating a temporary alleviation of market concerns regarding small-cap stocks [28] Convertible Bond Market Factors - In the convertible bond market, valuations continue to rise, with the premium rate for bonds converting at 100 yuan increasing and approaching the peak seen in May. The proportion of bonds with low conversion premiums has significantly decreased, while market transaction volume remains stable within a fluctuating range [31]

Core Viewpoint - Geopolitical conflicts provide a new opportunity for shorting energy and chemical commodities, with expectations that the current conflicts are unlikely to escalate into prolonged wars, and the short-term price surges are driven more by panic than substance [4][43]. Group 1: Geopolitical Conflict and Energy Market - The current geopolitical tensions, particularly the Israel-Iran conflict, are expected to have a short-term impact on energy prices, with the potential for a new bear market to emerge as the situation cools down [6][7]. - The closure of the Strait of Hormuz is deemed unlikely, as it would harm both Iran and unrelated major powers, and current oil flow levels remain normal [7]. - The energy price surge is characterized as an event-driven emotional cycle, with expectations of a gradual de-escalation of conflicts leading to a return to normal pricing levels [7][43]. Group 2: Energy Consumption Trends - China's transition to renewable energy has reached a critical point, with significant declines in coal and oil consumption, indicating a peak in fossil fuel usage that will negatively impact future global demand growth [12][45]. - The increase in traditional energy production is being driven by China and OPEC+, with China's output rising despite demand peaking, contributing to downward pressure on energy prices [17][19]. Group 3: Global Economic Pressures - The combination of tariffs and high debt levels is expected to suppress global demand, with the U.S. shifting from a consumer to a more protectionist stance, which will further impact global trade dynamics [21][28]. - The high levels of debt across major economies limit their ability to stimulate domestic demand, exacerbating the challenges posed by reduced U.S. consumption and trade deficits [25][28]. Group 4: Market Strategy and Outlook - The overall outlook for energy and chemical commodities remains bearish, with expectations that prices will first decline in upstream markets like crude oil and methanol before affecting downstream products [34][41]. - The strategy suggests shorting crude oil and methanol at high points, while monitoring the market for signs of inventory accumulation and weakening basis levels [34][45].

Report Summary 1. Industry Investment Ratings No industry investment ratings are provided in the report. 2. Core Views - The short - term pig price may have a small - scale rebound, but in the long - term, it will maintain a weak trend due to the supply - demand imbalance [1][2]. - The sugar price will stop falling and rebound in the short - term but will be in a weak oscillation in the medium - to - long - term as the global sugar market is expected to be in surplus [3][4]. - The crude oil price will fluctuate at a high level in the short - term due to the escalation of the Middle East situation, but will decline in the long - term as the supply increases and demand is restricted [5][7]. - PVC will run strongly in the short - term due to the impact of the Israel - Iran conflict, but its price may face pressure in the long - term as its supply - demand fundamentals are not strong [8][9]. 3. Summary by Variety Pig - **Supply**: As of June 20, the average weight of national pig slaughter was 123.78kg, down 0.18kg from the previous week. Due to policy and temperature factors, scale enterprises are accelerating the weight reduction of pigs [1]. - **Demand**: On June 20, the slaughtering rate was 28.13%, slightly up from the previous week. However, consumer demand for pork is low in summer, limiting the further increase of the slaughtering rate [1]. - **Strategy**: The short - term view is a continued rise, the medium - term view is a weak operation after a phased rebound, and the recommended strategy is to sell short on rallies [1][2]. Sugar - **International**: Tensions in the Middle East have pushed up oil prices, increasing the proportion of Brazilian sugar mills producing ethanol and reducing sugar supply. Brazil's sugar production in the second half of May increased year - on - year. India is expected to have a large increase in production in the new season, and Thailand is expected to produce 1005 million tons of sugar in the 2025/26 season [3]. - **Domestic**: As of the end of May 2025, the cumulative sugar production was 11.16 million tons, an increase of 1.2 million tons year - on - year.

Crude Oil - **Supply**: The US's raid on Iranian nuclear facilities has escalated the Middle East situation. Although the probability of Iran completely blocking the Strait of Hormuz is low, there is a risk of oil prices reaching $100 per barrel. Non - OPEC resources are expected to expand, and OPEC+ is maintaining a production - increasing strategy [5][6]. - **Demand**: In the US, the refinery operating rate has returned to normal levels, but the downstream demand is poor. In China, the operating rate of major refineries is approaching 80%, and the gasoline consumption has slightly improved, while diesel demand has decreased [6]. - **Inventory**: US commercial crude oil inventories have declined for four consecutive weeks, while fuel inventories have increased for three consecutive weeks. Oil inventories are expected to accumulate, suppressing the upside of oil prices [6]. - **Strategy**: The short - term view is high - level fluctuations, the medium - term view is a downward - pressured operation, and the recommended strategy is a combination of short futures positions and buying call options [5][7]. PVC - **Cost**: The supply of calcium carbide in the northwest region is tightening, and the demand from downstream is weakening. As of June 23, the price of calcium carbide in Wuhai, Inner Mongolia remained flat [8]. - **Supply**: The 200,000 - ton/year PVC device of Haohua stopped production last week. As of June 20, the weekly operating rate of the PVC industry was 78.62%, a decrease of 0.63 percentage points from the previous week [8]. - **Demand**: Some downstream enterprises have replenished their stocks, but the overall purchasing enthusiasm is not significantly improved. The export situation is expected to improve in the second half of the year, but the current orders have not increased significantly [8][9]. - **Inventory**: As of June 20, the social inventory of PVC was 355,100 tons, a decrease of 0.08% from the previous week and a decrease of 41.19% year - on - year [9]. - **Strategy**: The short - term view is range - bound fluctuations, the medium - term view is limited driving force for continuous growth, and the recommended strategy is to sell out - of - the - money call options on PVC at an appropriate time [8][9].
