A short history of money and markets

Knowing how markets came to be makes today's complexity feel logical rather than arbitrary.

From barter to money

Before money, people bartered — trading goods directly. The problem was the coincidence of wants: a fisherman wanting bread had to find a baker who happened to want fish. Money solved this by becoming a universally accepted middle step — first commodities like salt and metals, then coins, then paper backed by precious metals, and finally fiat money whose value rests on trust in the issuing state.

The first markets

As trade grew, merchants needed ways to fund voyages and share their risks. Out of this came:

• Bills of exchange and early banking in medieval and Renaissance Europe.
• Joint-stock companies in the 1600s — most famously the Dutch East India Company — which let many investors pool capital and share profits, the direct ancestor of the modern share.
• The first stock exchanges, such as Amsterdam, where those shares could be traded among investors.

The modern era

The 19th and 20th centuries brought central banks, standardized regulation, and eventually electronic trading, which collapsed distance and cost. In Brazil, organized exchanges trace back to the late 1800s; decades of mergers led to today's single exchange, B3, formed in 2017.

The thread through all of it is the same: each step made it easier, safer and cheaper to move money between savers and borrowers — exactly the purpose described in the previous lessons.
