交易所出手：上调涨跌停板幅度！

Core Viewpoint - The Shanghai Futures Exchange has announced adjustments to the trading margin ratio, price fluctuation limits, and trading limits for tin futures due to increased volatility in non-ferrous metal futures [2][4].

Group 2: Market Conditions and Price Trends - Tin prices have been on the rise, with the main tin futures contract on the Shanghai Futures Exchange reaching historical highs [8]. - Despite expectations for the Wa State region to lift the ban on tin mining, the actual recovery progress has not met market expectations, leading to tight supply conditions and low processing fees for tin ore [10][11]. - The demand from high-tech products remains relatively insensitive to tin price fluctuations, while capital expenditures from leading U.S. tech companies continue to expand rapidly, supporting a stable overall market for tin [11].
