Asian Clearing Union (ACU) is a form of payment arrangements whereby the participants settle payments for the transactions among the participating central banks on a multilateral basis.

The main objectives of a clearing union are: to facilitate payments among member countries for eligible transactions, to economize on the use of foreign exchange reserves and transfer costs, to promote trade among the participating countries.

The ACU is a clearing union among other clearing houses/payments arrangements operating in various regions of the world.


The ACU was established as an initiative of the United Nation Economic and Social Commission for Asia and the Pacific (UNESCAP). The decision to establish the ACU was taken at the Fourth Ministerial Conference on Asian Economic Cooperation held in December 1970 in Kabul. The Draft Agreement Establishing the ACU was finalized at a meeting of the senior officials of the governments and central banks held at ESCAP Meeting, Bangkok, in December 1974 after five central banks (India, Iran, Nepal, Pakistan, and Sri Lanka) signed the Agreement. Bangladesh and Myanmar were the sixth and seventh signatories to this Agreement.Bhutan signed the Agreement in 1999. As the ninth member, the Maldives joined the ACU in 2009.

Relations with Other Organizations and Clearing Arrangements

Currency Swap Arrangement

The main objective of the SWAP arrangement is to extend short-term foreign exchange support by providing participants access to the international reserves of other participants in times of temporary liquidity problems. The potential benefits of the SWAP facility are:

·         Easy access by participants to international reserves of other participants at a time when foreign exchange support is needed;

·         Availability of the facility on a multilateral basis rather than on a bilateral basis; and

·         The opportunity for further monetary cooperation among the participants.
