In dual releases published on January 25, 2017, the Financial Stability Board (FSB) expressed concern that re-use of collateral and re-hypothecation of client assets may pose financial stability issues. The financial crisis demonstrated that collateral re-use and re-hypothecation can transmit and amplify shocks to financial markets. While regulators have responded and prime brokers and clients have improved their risk management and practices since the crisis, the FSB has formulated recommendations to address residual financial stability risks associated with collateral re-use. In these releases, the FSB finalizes its data collection plans, and also explores whether uniform implementation of its recommendations is truly necessary, or whether a more flexible principles-base approach might be more effective.
