The National Bank

In banking, the term national bank carries several meanings:

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 of Canada of Montreal, Canada, is a privately owned commercial bank. 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.

Pashtany Bank is the government-owned bank in based in Kabul that controls Da Afghanistan Bank as well as the Afghan National Bank.

Argentina's national bank is the Banco de la Nación Argentina, founded in 1891.

The Commonwealth Bank of Australia was founded by an Australian Act of Parliament in 1911. Bank Nationalisation was the policy of the Andrew Fisher Labor Government. In a rare move for the time, the bank was to have both savings and general bank business. The bank was also the first bank in Australia to receive a Federal Government guarantee.

In 1958 and 1959, there was a controversy concerning the dual function of the bank as the central bank on the one hand and a general bank on the other. As a result of this, the bank was split, giving the reserve bank function to the Reserve Bank of Australia and the general bank function to the Commonwealth Banking Corporation.
