The short answer
The foreign exchange (forex) market is where currencies are exchanged for each other. It has no central building or single exchange. Most trading happens over the counter (OTC), which means directly between parties through dealer networks and electronic platforms. See OTC vs exchange for the difference.
The main forex market participants are:
- central banks
- commercial and investment banks
- corporations
- funds, such as asset managers, hedge funds, pension funds and sovereign funds
- retail traders, who trade through brokers
They trade for different reasons. Many have no interest in profit from price moves and need a currency only to pay for something. For background, read how forex works.
- Central banks and governments set interest rates and sometimes intervene.
- Large banks trade currencies with each other (the interbank market).
- Liquidity providers stream buy and sell prices to brokers.
- The broker shows its clients a bid and an ask price.
- Retail traders, companies and funds trade through brokers and banks.

Central banks
A central bank manages a country's money. In Pakistan this is the State Bank of Pakistan (SBP). Central banks hold foreign currency reserves, may buy or sell currency to slow sharp moves, and set the policy rate.
Motive: policy, not profit. They aim for stable prices, orderly markets and enough reserves to pay for imports and debt.
Influence: large, even when they do not trade. A change in the policy rate changes the return on holding a currency. That shifts the decisions of every other participant. The most recent SBP decision on our records is: SBP policy rate raised by 50 bps to 12% with effect from 27.10.2026 (MPC). For context, see SBP rates and economy.
Commercial and investment banks
Large banks form the core of the market, often called the interbank market. They quote buy and sell prices to each other and to their clients. The gap between those prices is the spread (see bid and ask).
Motives:
- Market making: quoting prices both ways and earning the spread.
- Client flow: carrying out currency exchanges for companies, funds and smaller banks.
- Own-account trading: taking positions with the bank's own capital, within internal limits.
Size: the largest by volume. A small group of global dealer banks handles a large share of all turnover. Their quotes are the base for the prices that brokers show further down the chain.
Corporations
Exporters, importers, airlines, oil companies and multinationals trade currency because their business requires it. A textile exporter paid in dollars must convert into rupees to pay staff. An importer of machinery must buy foreign currency to pay suppliers.
Motives: payments and hedging. Hedging means locking in a rate in advance, often with forwards or swaps, so that a currency move does not wipe out a business margin.
Influence: steady and real. Corporate demand reflects trade flows, so it ties exchange rates to the real economy over the long run.
Funds
This group includes several types:
- Asset managers and pension funds buy foreign stocks and bonds. They need the currency for those assets and may hedge the currency risk.
- Hedge funds take active positions on currencies, often based on interest rate differences and economic data (see fundamental analysis).
- Sovereign wealth funds invest a state's surplus abroad.
Size: large. Flows from big funds can move rates for days or weeks, especially when many funds act on the same view.
Retail traders
Retail forex traders are individuals who trade with their own money through a broker, usually by computer or phone. In most cases they do not exchange real currency. They trade contracts that follow the price, such as CFDs (see what is a CFD), often with leverage.
Motives: short-term speculation, meaning trying to profit from price changes.
Size: small in market share. Retail is the most visible group online, but it is a minor part of total turnover.
Risk: leveraged CFD and forex trading can lose money fast, and many retail accounts lose. See why traders lose.
Why retail does not move the market
There are several reasons:
- Order size. A single retail position is tiny next to a bank's or a fund's.
- Position in the chain. Retail orders reach the market through a broker. Depending on the model (see broker execution models and what a broker does), the broker may offset them internally or pass them on, often combined with others. They rarely reach the interbank market as separate orders.
- Price takers, not price makers. Retail traders accept the prices that dealers quote. The deep liquidity of major pairs absorbs their orders.
- Scattered direction. Retail traders buy and sell in different directions, so much of their flow cancels out.
For a retail trader, the practical point is this: the price will move for reasons set by central banks, banks, corporations and funds. Your trade will not change it.

Frequent questions
Who trades forex the most?
Large commercial and investment banks, by volume. Funds and corporations follow. Retail traders account for a small share.
Are banks in the forex market for profit or for clients?
Both. Most bank activity is quoting prices and handling client orders. Some banks also trade with their own capital within limits.
Can a central bank decide the exchange rate?
It can strongly influence the rate through the policy rate and by buying or selling currency. How far it does so depends on the country's exchange rate regime.
Do retail forex traders trade real currency?
Usually not. Most trade CFDs or similar contracts that follow the price, settled in cash through the broker.
Can many retail traders together move a price?
Not on major pairs in normal conditions. Their orders are small, pass through brokers and often offset each other.
