What is Forex Trading and How Does It Work in South Africa?

Forex trading (also called foreign exchange or FX trading) is the act of buying one currency while simultaneously selling another, with the goal of profiting from changes in their exchange rate. It is the most actively traded market on earth, with a daily turnover of more than $7.5 trillion. In this guide we explain exactly what forex trading is and how it works in South Africa, using plain language and simple examples.

What Is Forex Trading?

At its core, forex trading is speculation on the relative value of two currencies. Because you can never buy a currency in isolation, every forex trade involves a pair. When you buy EUR/USD you are buying euros and selling US dollars at the same time. If the euro strengthens against the dollar, your trade gains value.

How Does Forex Trading Work?

Forex trading works through a broker who gives you access to the currency market via a trading platform. You deposit funds, the broker provides leverage, and you open positions by buying or selling currency pairs. Your profit or loss depends on how far the price moves and the size of your position.

Currency Pairs

Every pair has a base currency (the first) and a quote currency (the second). The price shows how much of the quote currency is needed to buy one unit of the base. Pairs are grouped as majors (e.g. EUR/USD), minors (e.g. EUR/GBP) and exotics (e.g. USD/ZAR). South African traders often watch USD/ZAR, GBP/ZAR and EUR/ZAR alongside the global majors.

Pips and Lots

A pip is the smallest standard price movement, usually 0.0001 of the quote currency. Trade sizes are measured in lots — a standard lot is 100,000 units, a mini lot is 10,000 units, and a micro lot is 1,000 units. Beginners should start with micro lots to keep risk small.

Leverage and Margin

Leverage lets you control a large position with a small deposit called margin. With 1:100 leverage, R1,000 of margin controls a R100,000 position. This magnifies profits but equally magnifies losses, so responsible use of leverage is essential. Learn more in our forex trading for beginners guide.

A Simple Forex Trading Example

Suppose USD/ZAR is quoted at 18.50. You believe the US Dollar will strengthen, so you buy one mini lot. If USD/ZAR rises to 18.70, you have gained 20 “big figures” and your position is in profit. If it falls to 18.30 instead, you are at a loss. Using a stop-loss order would automatically close the trade at a level you choose, limiting your downside.

Who Trades Forex?

The forex market includes central banks, commercial banks, hedge funds, multinational companies hedging currency risk, and millions of retail traders. Thanks to online brokers and mobile apps, any South African with a smartphone and internet connection can now participate in the same market as the world’s largest institutions.

A Short History of the Forex Market

To fully understand what forex trading is, it helps to know where the modern currency market came from. For centuries, the value of money was tied to gold and silver. After World War II, the 1944 Bretton Woods Agreement pegged major currencies to the US Dollar, which was in turn convertible to gold. This created relatively fixed exchange rates and left little room for speculation. In 1971, US President Richard Nixon suspended dollar-to-gold convertibility, effectively ending the Bretton Woods system and ushering in the era of floating exchange rates that we still use today.

Once currencies were allowed to float freely, their values began to move according to supply and demand, interest rates and economic performance. Banks and large institutions started trading currencies electronically, and by the 1990s the internet made it possible for retail traders to access the market too. Today, the foreign exchange market is the largest and most liquid financial market in the world, dwarfing global stock markets in daily turnover. For South Africans, this evolution means that trading the US Dollar, British Pound, Euro or the Rand from a laptop or smartphone in Johannesburg, Cape Town or Durban is now completely normal.

Why the Forex Market Grew So Large

Several factors explain the enormous size of the modern forex market. First, international trade requires currency conversion — every time a South African company imports goods from China or exports minerals to Europe, currencies must be exchanged. Second, tourism and remittances move money across borders daily. Third, and most importantly for retail traders, speculation now accounts for the majority of daily volume. Traders and institutions buy and sell currencies purely to profit from price movements, adding depth and liquidity that benefits everyone in the market.

The Four Major Forex Trading Sessions

Because forex is a global market with no single physical location, it operates 24 hours a day across four major trading sessions that follow the sun around the world. Understanding these sessions helps South African traders decide when to trade for the best liquidity and volatility.

Sydney and Tokyo Sessions

The trading day opens with the Sydney session, followed closely by the Tokyo (Asian) session. In South African time (SAST), the Asian session runs roughly from midnight to 09:00. Pairs involving the Japanese Yen and Australian Dollar tend to be most active during these hours. Volatility is often lower than in later sessions, which some beginners find easier to manage.

London and New York Sessions

The London session, which opens around 09:00 SAST, is the single most important period in the forex day because Europe accounts for the largest share of global currency turnover. When the New York session opens in the early afternoon SAST, the overlap between London and New York produces the highest liquidity and the biggest price movements of the day. Many South African traders focus on this London–New York overlap, roughly 14:00 to 17:00 SAST, because tight spreads and strong momentum create excellent trading opportunities.

The Main Participants in the Forex Market

The forex market is often described as a pyramid. At the very top sit the major international banks that trade directly with one another in what is called the interbank market. Below them are smaller banks, multinational corporations, hedge funds, investment managers and central banks such as the South African Reserve Bank (SARB) and the US Federal Reserve. At the base of the pyramid are retail forex brokers and the millions of individual traders who access the market through them.

The Role of Central Banks

Central banks are among the most powerful players in forex. By setting interest rates and controlling the money supply, they directly influence the value of their national currencies. When the SARB raises interest rates, the Rand often strengthens because higher rates attract foreign investment. When the US Federal Reserve changes its policy, the effects ripple through every major currency pair. Retail traders pay close attention to central bank announcements because they frequently trigger sharp market movements.

Retail Traders and Brokers

Retail traders — ordinary people trading their own money — reach the market through online brokers. A broker aggregates prices from liquidity providers and offers them to you on a trading platform, usually adding a small spread as its fee. Choosing a well-regulated broker is one of the most important decisions a South African trader will make, which is why we maintain a detailed comparison of the best forex brokers in South Africa.

How Currency Quotes and Prices Work

Every forex price is a quote of one currency against another. When you see USD/ZAR = 18.50, it means one US Dollar is worth 18.50 South African Rand. The first currency (USD) is the base currency, and the second (ZAR) is the quote currency. If the price rises to 19.00, the Dollar has strengthened against the Rand; if it falls to 18.00, the Rand has strengthened against the Dollar.

Bid, Ask and the Spread

Brokers quote two prices for every pair: the bid (the price at which you can sell) and the ask (the price at which you can buy). The difference between them is the spread, which is effectively the cost of entering a trade. Major pairs like EUR/USD usually have very tight spreads, while exotic pairs like USD/ZAR tend to have wider spreads because they are less heavily traded. Keeping spreads low is important, especially for short-term traders who open many positions.

Going Long and Going Short

One of the most powerful features of forex trading is the ability to profit whether prices rise or fall. Going “long” means buying a pair because you expect it to rise. Going “short” means selling a pair because you expect it to fall. This flexibility means South African traders can look for opportunities in any market condition, although it also means losses can occur in either direction if the market moves against you.

Understanding the Risks of Forex Trading

No honest explanation of what forex trading is would be complete without a frank discussion of risk. The same leverage that can amplify profits can just as easily amplify losses, and it is entirely possible to lose your entire deposit. Research consistently shows that a large majority of retail traders lose money, particularly in their first year. This is not meant to discourage you, but to set realistic expectations.

How Traders Manage Risk

Successful traders survive by managing risk carefully. Common techniques include risking only a small percentage of your account on any single trade (often 1–2%), always using a stop-loss order, avoiding excessive leverage, and never trading with money you cannot afford to lose. Emotional discipline is just as important as technical skill; fear and greed cause more losses than bad analysis. Our forex trading strategies and techniques guide explains risk management in much greater detail.

Forex Regulation in South Africa

In South Africa, forex brokers and financial service providers are regulated by the Financial Sector Conduct Authority (FSCA). The FSCA licenses providers, enforces conduct standards and helps protect consumers. When choosing a broker, South African traders should look for an FSCA licence number or, at minimum, strong regulation from a respected international authority such as the UK’s FCA, Australia’s ASIC or Cyprus’s CySEC. Trading with a regulated broker gives you important protections that unregulated offshore platforms simply cannot offer.

Conclusion

Forex trading works by letting you speculate on the changing value of currency pairs using a broker and a trading platform. It offers genuine opportunity, low barriers to entry and round-the-clock access, but it also carries real risk because of leverage and volatility. Understand the basics, practise on a demo, use strong risk management, and only trade with a regulated broker. Ready to learn more? Explore forex trading for beginners next.
