20 Dollars HSBC

HSBC's position as one of three note-issuing banks in Hong Kong is a legacy of the colonial banking framework that survived the 1997 handover intact — an arrangement unique among major financial centers. The 2018 series was the first complete redesign HSBC had undertaken in over a decade, introducing updated security architecture as Hong Kong's HKMA pushed all three issuing banks toward a common modernization schedule.

Thomas De La Rue has printed HSBC's Hong Kong notes for well over a century, a relationship that has outlasted empires, occupations, and currency crises.
