DTCC

Overview

DTCC is the U.S. post-trade market-infrastructure institution named in the source’s explanation of why Robinhood restricted purchases during the 2021 GameStop volatility.

Current Profile

In the episode’s account, DTCC raised deposit requirements as concentrated, volatile, unsettled trades increased member exposure. This turns clearing into a visible constraint: a broker may offer immediate trading to customers while still needing enough capital to cover settlement and counterparty risk before trades complete.

Key Characteristics

• Sits in the clearing and settlement chain behind customer-facing brokerages.
• Uses member deposits or collateral to contain unsettled-trade risk.
• Can transmit volatility into immediate broker funding needs.
• Became central to the public legitimacy dispute around GameStop purchase restrictions.

Evidence

• Deposit pressure: EP159-GameStop：股票投资娱乐化/为什么价值投资不吃香了？ reports that DTCC sought substantially higher deposits from members during extreme GameStop trading.
• Broker response: EP159-GameStop：股票投资娱乐化/为什么价值投资不吃香了？ links the requirement to Robinhood’s effort to reduce new one-way exposure by limiting purchases.
