The story of the Office of the Comptroller of the Currency (OCC) and its role in the federal banking system begins in 1863, when the National Currency Act was passed by Congress and signed into law by President Abraham Lincoln.

For more than 150 years, the OCC has played a vital role in supervising national banks (and, since July 2011, federal savings associations) to ensure that they operate in a safe and sound manner and comply with applicable laws and regulations.
