20 South Sudanese Pounds

South Sudan's currency has been in near-continuous crisis since independence in 2011. By the time this note was printed, the country had already entered a second civil war (December 2013), and the pound was losing value rapidly against the dollar on both official and parallel markets. The 2015–2017 date range for this issue reflects the extended print run rather than a stable monetary environment — the central bank was struggling to maintain basic note supply as the economy deteriorated.

De La Rue's involvement here is straightforward contract printing; security feature provision was kept relatively modest for the denomination.
