美国期权清算暗藏雷区：巨头垄断引发担忧！

Core Viewpoint - The U.S. options market is on track for a sixth consecutive year of record trading volume, but concerns are rising among industry players about the market's heavy reliance on a few banks as primary market makers, which poses hidden risks [1][2]. Group 1: Market Dynamics - The Options Clearing Corporation (OCC) processes over 70 million contracts daily during busy trading periods, highlighting the significant volume handled by this central counterparty [1]. - The top five member institutions are expected to contribute nearly half of the OCC's default fund by the second quarter of 2025, indicating a high concentration of risk among a few players [1]. - Major banks like Bank of America, Goldman Sachs, and Dutch Bank dominate the market, taking on most of the market maker positions, which raises concerns about systemic risk if one of these institutions faces a crisis [1]. Group 2: Clearing and Margin Challenges - The OCC reported a 52% year-over-year increase in average daily trading volume in October, leading to a trend of market makers becoming direct members of clearinghouses, which carries its own risks due to their weaker capital compared to banks [2][5]. - Only a few clearing brokers can facilitate cross-margin trading between futures and options, which can reduce required margin sizes, indicating a limitation in the current market structure [5]. - Banks face challenges in providing margin discounts based on net risk levels due to their capital frameworks, which may lead to additional costs for clients [5]. Group 3: Regulatory and Operational Issues - The fragmented regulatory environment complicates the situation, with banks regulated by the Federal Reserve, while brokers and the options market fall under the SEC, and futures markets are overseen by the CFTC [6]. - The rise of zero-day-to-expiry options and increased retail trading volumes present new challenges for clearing members, especially if the market shifts to a 24/7 trading model [6]. - Upgrades and technological investments to handle increased trading volumes and risks may lead to higher costs for clients, as evidenced by Bank of America's increase in clearing fees from $0.02-$0.03 to a maximum of $0.04 per transaction [6]. Group 4: Default Fund Reform - The OCC proposed adjustments to the contribution calculation method for the $20 billion default fund to better reflect the market risks of each broker's portfolio [8]. - The current mechanism bases 70% of the contribution amount on members' ability to handle about 5% market volatility, which the OCC seeks to revise by considering historical market crashes [8]. - There is a call for more institutions to participate in the options clearing space to enhance competition and diversify risk management [8].
