Despite the efforts of the Bank of Finland, Swedish money remained widely used in Finland until 1840, when Finland went on the silver standard (following Russia), and the remaining Swedish paper money was withdrawn from circulation.
After this milestone, the notes issued by the Bank of Finland became the dominant means of payment in the country and the circulation was effectively controlled by the Bank of Finland. Finland obtained its own currency unit, the markka in 1860 – i.e. well before the country became independent.
