How did private bankers support the Dutch trading economy?

During the 17th century, as the Dutch economy expanded rapidly, modern banking institutions emerged to support its vast trading network. While the Amsterdamsche Wisselbank (Exchange Bank) was established in 1609 to facilitate monetary exchange and provide a secure system for settling accounts, it did not function as a lending institution for the general public.12

Private bankers played a crucial role in filling this gap by providing necessary credit to merchants and businesses. In addition to supplying capital, these private bankers acted as brokers in various financial transactions, helping to sustain the liquidity and efficiency required for the Dutch Republic's extensive international commerce.12
