In this puzzle, only some of the countries listed under each currency use that currency officially. These countries are highlighted below. To avoid confusion, no nations with similar-sounding currencies were included.
If the correct nations are taken as 1 and the incorrect nations are taken as 0, the table can be converted to binary, giving 00110, 00001, 01100, 10011, 00101, 00101, 00011, 01111, 01110, 01111, 01101, 11001. In decimal, that is 6, 1, 12, 19, 5, 5, 3, 15, 14, 15, 13, 25, which can be translated to the letters FALSE ECONOMY.
Astute solvers may have noticed that USD seems out of place, both in terms of name and alphabetically. This was a late change to replace the South African RAND, which is used in South Africa, as well as Eswatini, Lesotho, and Namibia, but those countries each have another national currency as well, which was causing confusion. Rather than rewrite the entire puzzle, I substituted the US dollar, which is the official currency in a surprising number of nations.
