A currency union (also known as monetary union) involves two or more states sharing the same currency without them necessarily having any further integration (such as an economic and monetary union, which would have, in addition, a customs union and a single market).

Three types of currency unions exist:

  1. Informal – unilateral adoption of foreign currency[citation needed]
  2. Formal – adoption of foreign currency by virtue of bilateral or multilateral agreement with the issuing authority, sometimes supplemented by issue of local currency in currency peg regime
  3. Formal with common policy – establishment by multiple countries of a common monetary policy and issuing authority for their common currency

The theory of the optimal currency area addresses the question of how to determine what geographical regions should share a currency in order to maximize economic efficiency.

Currency unions

Additionally the autonomous and dependent territories, such as some of the EU member state special territories, are sometimes treated as separate customs territory from their mainland state or have varying arrangements of formal or de facto customs union, common market and currency union (or combinations thereof) with the mainland and in regards to third countries through the trade pacts signed by the mainland state.[9]
