In banking, the term national bank carries several meanings:

  • especially in developing countries, a bank owned by the state
  • an ordinary private bank which operates nationally (as opposed to regionally or locally or even internationally)
  • in the United States, an ordinary private bank operating within a specific regulatory structure, which may or may not operate nationally, under the supervision of the Office of the Comptroller of the Currency.

In the past, the term "national bank" has been used synonymously with "central bank", but it is no longer used in this sense today. Some central banks may have the words "National Bank" in their name; conversely if a bank is named in this way, it is not automatically considered a central bank. For example, National-Bank AG in Essen, Germany is a privately owned commercial bank, just like National Bank of Canada of Montreal, Canada. On the other side, National Bank of Ethiopia is the central bank of Ethiopia and National Bank of Cambodia is the central bank of Cambodia.
