Regulations are not written in stone. The benefits derived from them, along with the costs of compliance for affected institutions and of enforcement for regulators, are likely to evolve. When this happens, regulators may seek to modify the regulations to better suit the specific risk profiles of regulated entities. In this post, we consider the Economic Growth, Regulatory Relief, and Consumer Protection Act (EGRRCPA) passed by Congress in 2018, which eased banking regulations for smaller institutions. We focus on one regulation—the Liquidity Coverage Ratio (LCR)—and assess how its relaxation affected newly exempt banks’ assets and liabilities, and the resilience of the banking system.
