Sudan's economy was in freefall during this note's active years. The secession of South Sudan in 2011 had stripped Khartoum of roughly 75% of its oil revenues, and by 2019 the country was grappling with triple-digit inflation that made high-denomination notes necessary almost immediately upon issue. The 500 Pound denomination, worth a fraction of its face value within months of release, was itself superseded when Sudan redenominated and introduced a new pound series as part of broader post-Bashir transitional reforms.
The cotton substrate and colour-shifting elements suggest a specification ordered from an established security printer, though the precise printer for this series has not been publicly confirmed by the Central Bank.
