2026年首调融资保证金100%，杠杆率回落至1倍，两融余额已创2.67万亿新高

Core Viewpoint - The China Securities Regulatory Commission has approved an increase in the minimum margin ratio for margin financing from 80% to 100%, effective January 19, 2026, as a response to the rapid growth of leveraged funds in the market [1][3]. Group 1: Policy Adjustment - The new margin ratio applies only to newly opened financing contracts, while existing contracts will continue to follow the previous margin requirements [3]. - The adjustment is linked to the recent active financing transactions and relatively ample market liquidity, with the margin financing balance reaching a historical high of 2.67 trillion yuan as of January 12 [3]. Group 2: Historical Context - The margin ratio has been adjusted in response to market conditions historically, with previous increases and decreases occurring in November 2015 and September 2023, respectively [3]. - The current increase from 80% back to 100% is seen as a regulatory measure to manage the rapid expansion of leveraged funds [3]. Group 3: Impact on Investors - The adjustment directly affects the leverage ratio for investors; for example, with a margin of 1 million yuan, the financing amount decreases from 1.25 million yuan (leverage of 1.25) to 1 million yuan (leverage of 1) [3]. - This indicates a reduction in the funding leverage capability for new financing [3]. Group 4: Market Reactions - Historical data shows that the market's short-term performance following previous adjustments has been mixed, with limited fluctuations in the CSI 300 index [4]. - The exchanges emphasize that the increase in the margin ratio is intended to lower leverage levels and protect investors' rights, promoting long-term market stability [4].
