The Central Bank of the Solomon Islands will release an updated SBD 100 banknote in October 2026. The note retains its existing design but adds an enhanced security thread that changes from green to red when tilted and produces a pulsing movement effect. Other security features include raised ink, an eagle portrait watermark visible when held to light and hidden elements that glow in two colors under ultraviolet light. The updated note will be available through commercial banks and will circulate alongside the existing SBD 100 banknote.
