Much of what you desire to know will be summed up by researching both the history of Marine Insurance, perhaps starting with the founding of Lloyd's Coffee House in about 1688; the history of the early trading companies such as
United East Indian Company (aka Dutch East India Company) (1602) - ; and
The Governor and Company of Adventurers Trading into Hudson's Bay (1670) ;
as well as the early banking arrangements established by Europe's key trading cities (eg Amsterdam in 1609, Hamburg in 1619, and Nuremberg in 1621) modelled after the Venetian Initiative already proven by Venice, Genoa and Barcelona.
Note that by the beginning of the 17th century all of Europe west of the Dvina-Dnieper line (at least) had a well established banking system offering Bill of Exchange (ie chequing) services and Foreign Exchange markets (also here) . Antwerp has a functioning Stock Exchange starting from 1531, and all those East India Companies were simply long-lived extensions of the limited liability concept that had long been used to finance risky maritime trade on a voyage-by-voyage basis. Somewhat coarsely, the financing which Antonio provides to Bassanio in Shakespeare's Merchant of Venice illustrates the mechanism.
