100.000 So'm

The 100,000 so'm note was Uzbekistan's highest denomination at issue and reflected a currency that had been chronically undervalued for years — by the mid-2010s, the black market rate for the US dollar ran at roughly double the official rate, a gap the Mirziyoyev government officially closed with the September 2017 liberalization. That single policy decision collapsed the parallel market overnight and forced a rapid rethink of the denomination structure; notes of this face value became practical necessities rather than curiosities.

Cotton substrate is consistent across the current Uzbek series, sourced domestically — Uzbekistan remains one of the world's major cotton producers, which gives the choice a certain logic beyond tradition.
