200 Ouguiya

Mauritania's switch to polymer for this series was partly driven by the country's climate — extreme heat and wind-blown sand degrade cotton-paper notes rapidly in the Saharan interior. G+D's Leipzig facility has handled polymer substrate printing for a number of West African central banks, and the 200 Ouguiya was among the earlier Mauritanian denominations converted under the new format adopted ahead of the 2018 currency redenomination, which dropped two zeros and introduced the new ouguiya at 1:10 against the old.
