20 Sucres

Ecuador's 20 Sucre notes of this period were issued against a backdrop of severe economic stress — inflation was accelerating sharply through the late 1980s, and the denomination was already losing practical purchasing power faster than the printing cycle could keep pace with. Within a few years, the sucre would require notes in the tens of thousands to conduct ordinary transactions.

Thomas De La Rue's London presses handled the series, with watermark security as the primary anti-counterfeiting measure — modest by contemporary standards, though adequate for a denomination that inflation was rapidly rendering negligible anyway.
