What are the financial markets?
Market Basics — Lesson 1 of 5 · 4 min read
A financial market is not a building or a screen — it is an agreed place where someone who wants to sell meets someone who wants to buy. When you buy dollars at a bureau de change you are inside a financial market; when a bank buys a billion euros it is in the same market. Only the size and the plumbing differ.
What makes a market a market is three things: an instrument that trades (a currency, a share, gold, a contract), a price the two sides agree on at that moment, and liquidity — enough buyers and sellers that you can get in and out whenever you want.
Why do these markets exist at all?
Markets were not built for speculation but out of genuine need. An importer paying in local currency needs euros; a refinery needs to lock in the price of oil it will buy in six months; a pension fund needs to put its members’ money into company shares. All of them deal because their business requires it.
The speculator came later, and — contrary to what people assume — plays a useful role: they are the side willing to buy when everyone wants to sell, providing liquidity and narrowing the gap between the buy and sell price.
The markets individuals trade today
- The currency market (forex) — the largest of all; daily turnover is measured in trillions of dollars.
- Metals — gold, silver and platinum, gold above all for its role as a haven in troubled times.
- Energy — crude oil in its two grades, and natural gas.
- Indices — baskets representing the performance of a large group of shares, such as the Dow and the Nasdaq.
- Stocks — ownership stakes in listed companies.
- Crypto — Bitcoin, Ethereum and others; the newest and the most volatile.
An important point: these markets are not separate. When the US central bank raises rates, the dollar, gold, the indices and Bitcoin all move in the same instant. Someone who understands several markets reads the picture more clearly than someone who confines themselves to a single pair.
What are you actually buying?
When you open a buy on gold from a trading account, you almost certainly do not own a bar in a vault. You have entered a contract on the price difference between you and your broker: if price rises you take the difference; if it falls you pay it. This is called a contract for difference, and it gets a full lesson of its own in this chapter — understanding it is the condition for understanding everything that follows.
