During ancient times, Indians were masters of seaborne trade between Europe, Asia, and Africa. They exported fine cotton, silk, spices, indigo, sugar, drugs, precious stones, and art in exchange for gold and silver. An indigenous banking system operated in India, which involved individuals and private firms receiving deposits and lending money. However, the advent of British rule and later nationalization of banks led to a decline of indigenous banking. Some major indigenous banks included Gujarati and Multani shroffs, as well as Chettiars and Marwari kayas.
