Foreign exchange plays a critical role in international trade by enabling market participants to achieve their corporate and individual goals and objectives, thereby fulfilling their foreign exchange strategies and minimising balance sheet risks.
Central banks manage forex reserves to achieve specific objectives and strategies in support of their local currencies and foreign exchange control regulations and policies. These policies are mandated by constitutional provisions and Acts of Parliament.
Foreign exchange control regulations and policies depend on the following factors, among others:
1. Imports
The more locals purchase goods and services from global counterparties, the greater the pressure on the domestic currency. Increased foreign purchases strengthen foreign currencies relative to the local currency, which may depreciate unless there is a sustainable supply of forex reserves to support and stabilise it. In some cases, exchange control regulations and import/export policies are implemented to manage volatility in the domestic currency.
2. Exports
Selling goods and services to foreign entities generates much-needed foreign currency, which can strengthen the local currency relative to foreign currencies. Some countries implement favourable policies for exporters to enhance foreign currency earning capacity. Special economic zones created for specific industries support export-oriented companies by reducing taxes, easing entry barriers, providing government guarantees and facilitating access to foreign markets.
3. Gross Domestic Product (GDP)
GDP represents the total value of goods and services produced by a country. Strong GDP growth can lead to currency appreciation, while weak GDP growth may lead to depreciation. Forex markets react to these macroeconomic indicators.
4. Interest Rates
Central banks adjust interest rates in response to economic conditions. They raise rates to cool the economy and lower rates to support a declining economy. Forex rates respond to movements in interest rates, and traders should anticipate and position themselves accordingly.
5. Balance of Payments
The balance of payments records a country’s inflows and outflows in international transactions. It influences central bank exchange rate policy through surplus or deficit positions.
Foreign Exchange Defined
Foreign exchange is the buying and selling of currencies. It involves exchanging one unit of currency for another, with value and delivery determined by contractual terms and applicable international and local exchange control regulations.
Foreign Exchange Terms
Spot
Spot trading refers to the exchange of two currencies with settlement typically two business days after the trade date. For example, a deal concluded on Monday, 19 January 2026, with spot value will settle two business days later (excluding weekends and holidays), on Wednesday, 21 January 2026. Counterparty and settlement risks must be carefully managed to avoid losses.
Forward Transactions
These are transactions with settlement dates beyond spot and include:
- Forward Contracts
Two parties agree privately to transact at a predetermined price and quantity for delivery after the spot date. - Futures Contracts
These are standardised contracts traded on an exchange. Settlement occurs through the exchange’s clearing mechanisms. Futures require margining, and positions are marked-to-market daily until closure or expiry. A party in deficit after mark-to-market must post variation margin. If the margin falls below maintenance levels, additional margin is required.
Pip
A measure of price movement in a currency pair.
Spread
The difference between the buying and selling price of a currency pair.
Mechanics of Trading Forex
Always identify the base currency in a currency pair. A client’s instruction to buy or sell relates to the base currency.
For example, in USD/ZAR, USD (United States Dollar) is the base currency. If a client instructs the purchase of USD using ZAR, the broker will sell ZAR and buy USD on the client’s behalf. Understanding which side of the pair to activate is essential when trading independently.
Factors to Consider When Trading Forex
1. Liquidity
Liquidity allows traders to enter and exit positions easily. Illiquid currency pairs exhibit low trading activity, limiting flexibility.
2. Trading Plan
A trading plan should align with defined goals and constraints. It includes time horizon, capital allocation, exit strategy and entry criteria. Trading without a plan allows emotion to dominate, which can result in avoidable losses.
3. Risk Management
Risk management is essential in varying economic environments. A trader’s ability to anticipate and apply appropriate risk mitigation strategies is crucial in containing losses and protecting gains. Stop losses, position sizing and hedging are important tools.
4. Leverage
Leverage can magnify both profits and losses. It should be used cautiously and within predefined limits in a trading plan.
5. Brokers
Choose legal and registered brokers regulated by the Financial Sector Conduct Authority (www.fsca.co.za). Be cautious of unregulated online trading platforms. Always verify a broker with relevant regulatory authorities before committing funds. Select a broker whose cost structure aligns with your trading strategy.
Commentary
Many individuals lose money by entering forex trading without proper training and education.
Irresponsible use of technology, including artificial intelligence, has also resulted in losses due to inadequate understanding.
Conclusion
Understanding local and foreign exchange control regulations, structuring a clear trading plan, mastering the mechanics of trading and applying sound risk management principles are prerequisites for successful forex trading. Risk mitigation is vital in minimising losses and enhancing returns in different economic environments.
