The Bahamian dollar is pegged to the U.S. dollar on a one-to-one basis. The Central Bank of The Bahamas states that it uses reserve requirements, changes in the Bank discount rate and selective credit controls, supplemented by moral suasion as main instruments of monetary policy, the objective of which is to keep stable conditions, including credit, in order to maintain the parity between the U.S. dollar and the Bahamian dollar while allowing economic development to proceed.
Although the U.S. dollar (as any other foreign currency) is subject to exchange control laws in The Bahamas, the parity between Bahamian dollars and U.S. dollars means that any business will accept either U.S. or Bahamian currency and many of the businesses that serve tourists have extra U.S. dollars on hand for the convenience of American tourists.
The dollar replaced the pound at a rate of 1 dollar = 7 shillings in 1966. This rate allowed the establishment of parity with the U.S. dollar, due to the sterling/dollar rate then being fixed at £1 = $2.80. It may also explain the unusual 15 cent coin, since this was roughly equivalent to 1 shilling.
