Core Viewpoint - The Dalian Commodity Exchange (DCE) is set to launch its first cash settlement for monthly average price futures of linear low-density polyethylene (LLDPE), polyvinyl chloride (PVC), and polypropylene (PP) on January 30, 2026, marking a significant development in the futures market [1][2]. Group 1: Futures Contract Details - The contracts involved are L2602F, V2602F, and PP2602F, with the delivery date coinciding with the last trading day of the contract month, specifically the last trading day of January 2026 [1]. - The settlement price for these contracts will be the arithmetic average of the daily settlement prices during all trading days of the previous month [1]. Group 2: Cash Settlement Mechanism - Unlike traditional physical delivery futures, these monthly average price futures will utilize a cash settlement model, where the DCE will directly transfer profits and losses based on the settlement price, eliminating the need for physical delivery [1]. - The delivery fee for these contracts is set at 1 yuan per hand, but the DCE will waive this fee until December 31, 2026, for all but high-frequency traders [2]. Group 3: Preparatory Measures and Market Impact - To ensure a smooth implementation of the first cash settlement, the DCE has conducted two market-wide tests focusing on the reliability of settlement price calculations and profit-loss allocations [2]. - The DCE aims to complement existing physical delivery futures with this cash settlement mechanism, enhancing the overall chemical derivatives ecosystem [2]. - Market participants are advised to closely monitor market dynamics, positions, and delivery progress to ensure a stable cash settlement process [2].

Core Viewpoint - The introduction of polypropylene monthly average price futures with cash settlement enhances risk management tools for the industry by aligning with the common pricing practices in spot trade [1] Group 1: Cash Settlement Mechanism - Cash settlement means that upon contract expiration, the exchange completes profit and loss settlement through cash transfer rather than physical delivery of goods [1] - The settlement price for polypropylene monthly average price futures is the arithmetic average of the settlement prices of the corresponding physical delivery futures for all trading days in the month prior to the contract month [1] Group 2: Market Functionality - The monthly average price futures financialize the commonly used "monthly average" pricing benchmark in spot trade, filling a gap in the domestic futures market regarding average price management [1] - Plastic processing, modification, and trading companies can lock in or hedge against the average procurement costs of raw materials for future months, mitigating the impact of price volatility on production profits [1] - Upstream refining companies can sell the average price in advance, stabilizing their monthly sales revenue [1] Group 3: Liquidity and Participation - The cash settlement mechanism ensures contract liquidity by eliminating warehouse receipt pressure and delivery default risks, encouraging more financial institutions and quantitative funds to participate [1] - Increased participation enhances the depth and breadth of price discovery in the market [1]

Group 1 - The core concept of stock index futures trading is likened to sailing, where preparation, execution, and risk management are crucial for smooth navigation in the market [1] Group 2 - Prerequisites for stock index futures trading include a minimum margin account balance of 500,000 yuan, basic knowledge of stock index futures, and a record of simulated trading or commodity futures trading [2] - The process of opening a stock index futures account involves selecting a qualified futures company, providing identification and bank details, filling out risk assessment questionnaires, signing agreements, and depositing margin [2][3] Group 3 - Familiarity with trading software is essential, as it includes sections for market data, trading, and positions, similar to a car's dashboard and cockpit [4] - New traders are encouraged to practice in a simulated environment to become proficient before engaging in real trading [4] Group 4 - The main steps in stock index futures trading are opening a position, holding a position, and closing a position, with specific actions required for each step [6] - Different order types include market orders for immediate execution and limit orders for specific price targets [6] Group 5 - Margin management is critical in stock index futures trading, where investors only need to deposit a fraction of the contract value as margin [6] - For example, with a contract value of 900,000 yuan and a margin ratio of 10%, an investor would need to deposit 90,000 yuan [6] Group 6 - During trading, margin requirements may change with contract price fluctuations, and investors must maintain sufficient margin to avoid forced liquidation [7] Group 7 - Stock index futures contracts are settled in cash upon expiration, with automatic calculations of gains and losses based on the settlement price [8] - Investors are advised to close positions before expiration to avoid liquidity issues and increased trading costs [8]

Core Viewpoint - The article explains how the settlement price of stock index futures is determined, emphasizing fairness, transparency, and resistance to manipulation in its calculation methods [1]. Group 1: Calculation Methods - The most common method is the arithmetic average, exemplified by the China Financial Futures Exchange (CFFEX) using the last two hours' average price of the CSI 300 index on the last trading day [4]. - During the last trading day from 13:00 to 15:00, index points are recorded every 5 seconds, and the arithmetic average of all points is taken as the settlement price [5]. - The purpose of extending the calculation period and high-frequency sampling is to reduce the impact of single trades or short-term fluctuations on the settlement price, thus preventing market manipulation [6]. Group 2: Specific Calculation Examples - The Singapore Exchange (SGX) uses the closing price of the index on the last trading day for its FTSE China A50 index futures [7]. - This method is simple but may increase market volatility risk during the closing period due to concentrated trading by participants [8]. - Some exchanges may use a volume-weighted average price (VWAP) that combines price and volume to calculate the average [9]. Group 3: Design Logic - The design logic aims to prevent market manipulation; using only the closing price could allow large players to influence the settlement price through significant trades at the last moment [11]. - The calculation period is typically chosen during active market hours to ensure that prices reflect supply and demand accurately [11]. - The rules for calculating the settlement price are clearly defined at the contract's listing, ensuring transparency and predictability for all participants [12]. Group 4: Role of Settlement Price - The settlement price serves as the basis for cash settlement in stock index futures, directly determining the profit and loss for both long and short positions [12]. - The convergence of the settlement price with the spot index on the expiration date is fundamental for the basis of arbitrage between futures and spot markets [13].
