The historical distinction of the world's first formal savings bank is widely attributed to the founding of the Savings and Friendly Society, established in the village of Ruthwell in Dumfriesshire, Scotland, in 1810 by Reverend Henry Duncan. Designed specifically to encourage financial thrift, regular savings habits, and economic self-reliance among working-class laborers and rural families, the institution paid modest interest on small deposits. This revolutionary mutual savings model served as the blueprint for the trustee savings bank movement across Great Britain and directly inspired the creation of early mutual savings institutions in the United States, transforming modern personal finance for ordinary citizens.
