The primary regulator of all federally chartered and many state-chartered thrift institutions, which include savings banks and savings and loan associations. The goal of the OTS is to ensure that thrift institutions donÂ’t default and to support their role as home mortgage lenders and providers of community credit and financial services. It was established as a bureau of the U.S. Department of the Treasury on August 9, 1989, and has four regional offices located in Jersey City, New Jersey; Atlanta, Georgia; Dallas, Texas; and San Francisco, California. The office is funded by assessments and fees levied on the institutions it regulates.
