On July 6, 2016, OCC, along with 30 other exchanges, clearing organizations, and market participants, sent a letter to the Basel Committee on Banking Supervision regarding the Consultative Document on Revisions to the Basel III Leverage Ratio Framework. The letter states that unless the Standardized Approach for Counterparty Credit Risk (SA-CCR) method is allowed as a replacement for the Current Exposure Method (CEM) in the leverage calculation for exchange-traded derivative exposures, the application of the leverage ratio will result in vastly increased capital requirements for general clearing members offering clearing services to market makers and liquidity providers. The letter says this action will fundamentally threaten their business models and impact the liquidity and stability of global financial markets, and would be contrary to the G20 commitments on central clearing.
