1000 Francs 9th series

The 9th series was conceived as a complete redesign — not an incremental refresh — and took years longer to complete than originally announced, with the 1000 franc note arriving last in 2019 despite the 2017 series date. Switzerland's 1000 franc note has long held the distinction of being the highest-denomination banknote in regular circulation among developed economies, a fact that periodically draws international scrutiny given its utility in large cash transactions.

Durasafe, developed by Landqart, bonds a polymer core between two layers of cotton paper — giving the note tactile properties familiar to Swiss users while substantially increasing resistance to soiling and mechanical wear.
