1. Report Industry Investment Rating - No relevant content provided 2. Core View of the Report - The urea market is in a pattern with support below and suppression above, and the 09 contract is expected to fluctuate weakly. In the short - term, the export of the second batch of urea supports the demand side, and inventories are unlikely to accumulate significantly. However, agricultural demand is gradually weakening, and the fundamentals will continue to face pressure in the second half of the year [4]. 3. Summary According to Relevant Catalogs 3.1 Urea Price Interval Forecast - The price interval forecast for urea in the next month is 1650 - 1950, with a current 20 - day rolling volatility of 27.16% and a 3 - year historical percentile of 62.1%. For methanol, the price interval is 2200 - 2400, with a volatility of 20.01% and a historical percentile of 51.2%. For polypropylene and plastic, the price intervals are both 6800 - 7400, with volatilities of 10.56% and 15.24% respectively, and historical percentiles of 42.2% and 78.5% [3]. 3.2 Urea Hedging Strategy 3.2.1 Inventory Management - When the finished - product inventory is high and there are concerns about a decline in urea prices, companies can short the urea futures (UR2509) with a 25% hedging ratio at an entry interval of 1800 - 1950. They can also buy 50% of put options (UR2509P1850) to prevent a sharp price drop and sell 50% of call options (UR2509C1950) to reduce capital costs [3]. 3.2.2 Procurement Management - When the procurement inventory is low and there are concerns about a rise in urea prices, companies can buy urea futures (UR2509) with a 50% hedging ratio at an entry interval of 1750 - 1900. They can also sell 75% of put options (UR2509P1750) to collect premiums and lock in the purchase price if the price drops [3]. 3.3 Core Contradiction - A large amount of speculative funds left the market on Friday night, and the urea futures are expected to decline, which will put pressure on the spot market. In the medium - term, the second - batch export of urea supports the demand side, and inventories are unlikely to accumulate significantly in the short - term. Factory inventories and pending orders are not under much pressure, and spot prices are slightly fluctuating, which supports the urea price. However, agricultural demand is gradually weakening, and the fundamentals will face pressure in the second half of the year [4]. 3.4利多解读 and 利空解读 - Urea exports have been confirmed, and the futures are expected to show a wide - range shock pattern with enhanced downward support. The domestic policy requires factories to sell urea at low prices, which has a negative impact on the spot market sentiment [5].

Report Overview - Report Name: Nanhua Futures Copper Risk Management Daily Report - Date: July 28, 2025 - Research Team: Nanhua Non - ferrous Metals Research Team [1] Investment Rating - No investment rating for the copper industry is provided in the report. Core Views - Copper prices recently rose and then fell. The rise was due to the positive impact of domestic anti - involution on commodities and increased copper demand expectations from Yajiang Hydropower Station construction. However, the short - term impact of both factors on copper should be limited. The supply side has no significant over - capacity to eliminate, and anti - involution in the downstream is more negative than positive for demand. The long construction cycle of the hydropower station means low initial copper demand. The increase in copper prices was likely a passive rise due to capital overflow from other sectors. In the short term, as the anti - involution hype fades, copper prices may decline slightly. The upcoming week is a macro super - week with significant events that could cause large price fluctuations in copper during the last week of July [3]. Summary by Directory Copper Price and Volatility - The latest copper price is 79,250 yuan/ton, with a monthly price range forecast of 73,000 - 80,000 yuan/ton. The current volatility is 11.64%, and the historical percentile of the current volatility is 22.6% [2] Copper Risk Management Suggestions - **Inventory Management**: For high finished - product inventory and fear of price drops, with a long spot position, it is recommended to sell 75% of the Shanghai Copper Main Futures Contract near 82,000 yuan/ton and sell 25% of the CU2509C82000 call option when volatility is relatively stable [2] - **Raw Material Management**: For low raw - material inventory and fear of price increases, with a short spot position, it is recommended to buy 75% of the Shanghai Copper Main Futures Contract near 75,000 yuan/ton [2] Factors Affecting Copper Prices - **Likely Positive Factors**: Sino - US tariff policy relaxation, lower LME inventory levels, the US dollar index hovering at a low level, and anti - involution benefiting the non - ferrous metals sector [4][7] - **Likely Negative Factors**: Tariff policy reversals, reduced global demand due to tariff policies, and the Fed maintaining high interest rates [7] Copper Futures Market Data | Contract | Unit | Latest Price | Daily Change | Daily Change Rate | | --- | --- | --- | --- | --- | | Shanghai Copper Main | yuan/ton | 79,250 | 0 | 0% | | Shanghai Copper Continuous 1 | yuan/ton | 79,250 | - 640 | - 0.8% | | Shanghai Copper Continuous 3 | yuan/ton | 79,240 | 0 | 0% | | LME Copper 3M | US dollars/ton | 9,796 | - 58.5 | - 0.59% | | Shanghai - London Ratio | ratio | 8.06 | - 0.06 | - 0.74% | [6][8] Copper Spot Market Data | Spot Type | Unit | Latest Price | Daily Change | Daily Change Rate | | --- | --- | --- | --- | --- | | Shanghai Non - ferrous 1 Copper | yuan/ton | 79,450 | - 345 | - 0.43% | | Shanghai Wumaotrade | yuan/ton | 79,535 | - 220 | - 0.28% | | Guangdong Southern Reserve | yuan/ton | 79,380 | - 270 | - 0.34% | | Yangtze Non - ferrous | yuan/ton | 79,640 | - 280 | - 0.35% | | Shanghai Non - ferrous Premium/Discount | yuan/ton | 125 | - 20 | - 13.79% | | Shanghai Wumaotrade Premium/Discount | yuan/ton | 115 | 10 | 9.52% | | Guangdong Southern Reserve Premium/Discount | yuan/ton | 115 | 15 | 15% | | Yangtze Non - ferrous Premium/Discount | yuan/ton | 125 | 0 | 0% | [10] Copper Scrap - Refined Spread Data | Spread Type | Unit | Latest Price | Daily Change | Daily Change Rate | | --- | --- | --- | --- | --- | | Current Scrap - Refined Spread (Tax - included) | yuan/ton | 840.74 | - 463.62 | - 35.54% | | Reasonable Scrap - Refined Spread (Tax - included) | yuan/ton | 1,492.45 | - 5.7 | - 0.38% | | Price Advantage (Tax - included) | yuan/ton | - 651.71 | - 457.92 | 236.3% | | Current Scrap - Refined Spread (Tax - excluded) | yuan/ton | 5,545 | - 470 | - 7.81% | | Reasonable Scrap - Refined Spread (Tax - excluded) | yuan/ton | 6,199.6 | - 39.56 | - 0.63% | | Price Advantage (Tax - excluded) | yuan/ton | - 654.6 | - 430.44 | 192.02% | [12] Copper Warehouse Receipt and Inventory Data - **SHFE Copper Warehouse Receipts**: Total Shanghai Copper warehouse receipts are 16,133 tons, a decrease of 0.31%.

1. Report Industry Investment Rating - No relevant content provided 2. Core View of the Report - The market theme remained clear this week, but the strength of the market exceeded expectations. Some varieties showed signs of taking over the upward trend on Friday. The exchange resolved the position - holding risk of the coking coal 09 contract through position limits and promoted position transfer. The overall market's bullish trend is unlikely to reverse completely due to position limits, but future market movements may not be as intense, and differentiation will be more obvious. The black sector is generally bullish [3][5]. 3. Summary by Related Catalogs 3.1 Week - long Market Data Overview - The market continued the "anti - involution" theme this week. Under the notice of controlled coal over - production, coking coal led the market. The coking coal 09 contract had 4 out of 5 K - lines hitting the daily limit this week. After a sudden news on July 22, it hit the daily limit, with partial short - covering and fluctuations on the 23rd. It added 50,000 lots on the 24th and 25th, maintaining its strength. Many related varieties such as glass, soda ash, PVC, and ferrosilicon also strengthened significantly. However, on Friday night after the Dalian Commodity Exchange limited the position of the coking coal 09 contract to 500 lots, coking coal, glass and other varieties corrected sharply, and the coking coal 09 contract reduced its position by 100,000 lots. Since July 22, the coking coal 09 contract only rose by 92 points (less than 10%) by Friday night's close. The position limit successfully released the potential risk of the coking coal 09 contract's reluctance to transfer positions, but it is unlikely to reverse the trend of the leading variety in the anti - involution market. Similar cases in the past show that position limits are to prevent extreme market risks and do not change the variety's trend, but large fluctuations require risk control [4]. 3.2 Variety Price Movement Structure - From last week's variety price movement structure, low - priced varieties have shown a comprehensive upward trend, and some varieties have signs of continuing the bullish market. This is a systematic market that will not end abruptly due to the position limit on coking coal. Funds may look for new varieties to take advantage of the good market profit - making effect [5]. 3.3 Capital Flow in Different Sectors - The total capital flow was 14.391 billion. Among them, precious metals had a capital flow of 522 million, non - ferrous metals 5.558 billion, black metals 85 million, energy 72 million, chemicals 517 million, feed and breeding - 239 million, oils and fats - 1.769 billion, and soft commodities 164 million [9]. 3.4 Weekly Data of Different Commodity Categories - **Black and Non - ferrous Metals**: Data on price percentile, inventory percentile, valuation percentile, position percentile, position difference percentile, and annualized basis for various black and non - ferrous metal varieties such as iron ore, rebar, hot - rolled coil, coking coal, etc. were provided [9]. - **Energy and Chemicals**: Similar data for energy and chemical varieties like fuel oil, low - sulfur oil, asphalt, etc. were presented [11]. - **Agricultural Products**: Data for agricultural products including soybean meal, rapeseed meal, soybean oil, etc. were given [12].
