Foreign exchange trading did not spring fully formed — it evolved from barter to gold, fixed systems and today's trillion-dollar electronic market. Understanding the history explains why forex behaves as it does.
From Barter to Money
Barter required matching needs; money solved it, then international trade demanded ways to exchange currencies — the origin of FX.
Gold and the Gold Standard
Currencies were tied to gold, fixing exchange rates and stabilising trade, until wars and deficits broke the system.
Bretton Woods and Floating Rates
After WWII, fixed-but-adjustable rates pegged to the dollar; when that broke in the 1970s, rates floated and modern FX markets emerged.
The Digital Age
Electronic trading made FX the largest and most liquid market on earth — accessible to retail through brokers.
FAQ
Why do currencies float now?
Because central banks dropped rigid pegs in the 1970s, letting supply and demand set rates.
