On October 27, 2017, the Office of the Comptroller of the Currency (OCC) published a proposed rule that would have made several revisions to its stress testing regulation. The OCC is now adopting the proposed rule as final. The final rule changes the range of possible "as-of" dates used in the global market shock component to conform to changes already made by the Board of Governors of the Federal Reserve System (Board) to its stress testing regulations. The final rule also changes the transition process for covered institutions with $50 billion or more in assets. Under the final rule, a covered institution that becomes an over $50 billion covered institution, as that term is defined in the OCC stress testing regulation, before September 30 will become subject to the requirements applicable to an over $50 billion covered institution beginning on January 1 of the second calendar year after the covered institution becomes an over $50 billion covered institution, and a covered institution that becomes an over $50 billion covered institution after September 30 will become subject to the requirements applicable to an over $50 billion covered institution beginning on January 1 of the third calendar year after the covered institution becomes an over $50 billion covered institution. The final rule also makes certain technical changes to clarify the requirements of the OCC's stress testing regulation.
