Valuation
Pegged withSDR (1:1)
WAUA is defined by WAMA as equal to the IMF SDR.

WAMA states that 1 WAUA is equivalent to 1 SDR, making WAUA’s valuation anchored to the IMF’s SDR valuation framework.

History

WACH was established in 1975 as a multilateral payment facility to promote intra-subregional trade; it was transformed into WAMA in 1996. United Nations Economic Commission for Africa (UNECA) describes WAUA as an artificial unit of account linked to the IMF SDR, used as a benchmark in the WACH clearing mechanism.

Use

WAUA has been used for pricing/settlement in regional clearing arrangements and for monitoring exchange-rate movements within the ECOWAS monetary cooperation process. WAMA notes that it facilitates settlement within the sub-region through the introduction and use of WAUA and operates a clearing and payments system among member central banks.

Valuation

WAMA defines the relationship as 1 WAUA = 1 SDR. The IMF publishes official SDR valuation and reference exchange rates, which can be used to express WAUA in major currencies given the 1:1 equivalence.

Exchange rates

WAMA publishes daily exchange rate summaries that include WAUA alongside major currencies (such as USD, GBP and EUR) and other reported rates.
