突发，上调！

Core Viewpoint - Huayin Securities announced an increase in the financing margin ratio to 100% for securities listed on the Shanghai and Shenzhen stock exchanges, effective from October 13, 2025, to manage business risks and adapt to business development [2][5]. Group 1: Margin Ratio Adjustments - Huayin Securities is not the first brokerage to take such action; Guojin Securities previously raised its margin ratio from 80% to 100% starting August 27, 2023, citing operational considerations [5]. - The increase in margin ratio affects the amount investors can finance; moving from an 80% to a 100% margin means that investors now need 100 million yuan to buy 100 million yuan worth of securities, reducing the leverage ratio from 1.25 to 1 [5]. - The adjustment is seen as a measure to alleviate liquidity pressure faced by some small and medium-sized brokerages amid rising financing demand in the current active margin trading market [6]. Group 2: Market Activity and Trends - As of October 13, the total margin trading balance reached 2.444 trillion yuan, reflecting a daily increase of 25.94 billion yuan, with the margin balance accounting for 2.55% of the A-share market's circulating value, indicating high leverage activity [8]. - Several brokerages, including Huayin Securities, have raised the upper limit of financing business scales in response to strong demand; Huayin Securities increased its credit business limit from 62 billion yuan to 80 billion yuan within six months [8]. - The overall leverage level in the margin trading market is considered stable, with the expectation that the margin trading business will remain active as the A-share market continues to perform well [9].
