FX Spot vs. FX Forwards

What is the FX Market?

The FX or Foreign Exchange market facilitates the global exchange of currencies. It operates 24 hours a day and involves transactions between currencies. The market is highly liquid and includes participants such as central banks, asset managers, retail investors, commercial banks, corporations, and hedge funds.

What Is the Difference Between Spot and Forward Transactions?

Spot transactions involve the immediate exchange of currencies at the current spot rate, typically settling within two business days (T+2). Forward transactions, on the other hand, involve an agreement to exchange currencies at a future date beyond the spot date at a predetermined forward rate.

What is an FX Spot?

An FX spot transaction involves the immediate exchange of currencies at the current spot rate. It typically settles within two business days (T+2). For example, if you buy euros at today’s spot rate, you will receive the euros and pay the corresponding amount in another currency within two business days. Some currencies settle quicker, such as the USD/CAD which takes one business day.

Applications of FX Spot

FX spot transactions are widely used in various financial and business contexts due to their immediate settlement nature. Here are some key applications:

1. Payment Facilitation: FX spot transactions are commonly used to facilitate international payments. For example, a company may need to pay an overseas invoice in a foreign currency. By using an FX spot transaction, the company can convert its domestic currency into the required foreign currency at the current spot rate and make the payment immediately.
2. Risk Management: Businesses use FX spot transactions to manage currency risk. For instance, if a company has a payment due in a foreign currency shortly, it can use an FX spot transaction to lock in the current exchange rate and avoid potential losses due to unfavourable currency movements.
3. Speculation: Traders and investors use FX spot transactions to speculate on short-term currency movements. By buying or selling currencies at the current spot rate, they can take advantage of anticipated changes in exchange rates to make a profit.
4. Diversification: FX spot transactions allow investors to diversify their portfolios by including foreign currencies. This can help spread risk and potentially enhance returns by taking advantage of favourable currency movements.

What is an FX Forward?

An FX forward is an agreement to buy or sell a currency at a price agreed upon today, with settlement at an agreed-upon date after the spot date. It is used to lock in an exchange rate for a future transaction, protecting against exchange rate fluctuations.

The historical context of FX forwards includes significant events such as the collapse of Bankhaus Herstatt in 1974, which highlighted the risks associated with time zone differences in FX settlements. This event led to the development of global clearing and settlement systems to enhance the safety and efficiency of currency transactions.

Applications of FX Forwards

FX forwards are versatile financial instruments used for various purposes. Here are some key applications:

1. Hedging: FX forwards are commonly used by businesses to hedge against currency risk. For example, a European exporter expecting a payment of $100 million in three months can enter into a 3-month EUR/USD forward contract to lock in the exchange rate, ensuring that the payment value remains fixed regardless of any USD/EUR exchange rate movements.
2. Speculation: Traders and investors use FX forwards to speculate on future currency movements. By locking in a forward rate, they can potentially profit from favorable exchange rate changes.
3. Arbitrage: FX forwards can be used to exploit arbitrage opportunities. If there are discrepancies between the spot and forward rates, traders can buy and sell currencies to take advantage of the price differences.
4. Interest Rate Parity: FX forwards help maintain interest rate parity by ensuring that the difference in interest rates between two countries is reflected in the forward exchange rate. This prevents arbitrage opportunities and keeps the market balanced.
5. Risk Management: Businesses and financial institutions use FX forwards to manage their exposure to currency risk. By locking in exchange rates for future transactions, they can protect themselves from adverse currency movements.

Comparison with Other Financial Instruments

FX forwards and spots are compared with other financial instruments such as FX swaps, cross-currency swaps, and options. Here are some key differences:

• FX Spot vs. FX Forwards: FX spot transactions involve the immediate exchange of currencies at the current spot rate, typically settling within two business days (T+2). In contrast, FX forwards involve an agreement to exchange currencies at a future date beyond the spot date at a predetermined forward rate.
• FX Swaps: FX swaps involve the exchange of currencies at an initial rate and then exchanging them back at a later date. This means that FX swaps consist of two legs: a spot transaction and a forward transaction. FX spot transactions, on the other hand, only involve the immediate exchange of currencies. FX forwards involve an agreement to exchange currencies at a future date beyond the spot date at a predetermined forward rate.
• Cross-Currency Swaps: cross-currency swaps involve the exchange of principal and interest payments in different currencies. They are typically used to manage currency and interest rate risk. FX spot and FX forwards transactions do not involve interest payments and are used for immediate currency exchange.
• Options: these provide the right, but not the obligation, to buy or sell a currency at a fixed strike price within a specified period. FX spot transactions involve the immediate exchange of currencies at the current spot rate without any optionality.  FX forwards involve a binding agreement to exchange currencies at a future date at a predetermined rate without any optionality.

What Determines FX Forward Prices?

FX forward prices are primarily driven by interest rate differentials and the direction of adjustment. The calculations for forward prices are based on the principle that if there are two or more ways to achieve the same outcome, the prices of these alternatives must be identical.

How to Calculate FX Forward Rate?

FX Forward Rate Formula

FX forward rate = FX spot rate x  (1 + iquoted  x days / basis) / (1 + ibase  x  days / basis)

The formula for calculating the FX forward rate takes today’s spot rate and multiples it by the domestic spot rate divided by the foreign interest rate. We can use this formula to price a one-year forward for the GBP/USD rate at 1.36 with UK interest rates at 4.25% and US interest rates at 4.5%. This would be calculated as:

This takes into account the interest rate differential between the two currencies involved. If the calculation was required over a specific period rather than a year then this can be added into the formula. The greater the interest rate differential, the larger the gap between the spot and forward prices.

What Is the Difference Between FX Spot and FX Outright?

FX spot transactions involve the immediate exchange of currencies at the current spot rate, while FX outright transactions involve an agreement to exchange currencies at a future date beyond the spot date at a predetermined forward rate.

What is an FX Spot Forward Swap?

An FX spot forward swap involves the purchase of a currency at the spot rate and the sale of the same currency at a forward rate. For example, buying euros at today’s spot rate and selling the same euros six months later at a fixed forward rate.

What is Interest Rate Parity?

Interest rate parity is a financial theory that suggests the difference in interest rates between two countries is equal to the difference between the forward exchange rate and the spot exchange rate. This principle ensures that there is no arbitrage opportunity from the difference in interest rates between two countries.

Conclusion

Understanding the distinctions and applications of FX spot and forward transactions is crucial for effective currency management and risk mitigation. FX spots provide immediate currency exchange, while FX forwards offer a way to lock in future exchange rates, protecting against market volatility. By leveraging these financial instruments, businesses and investors can navigate the complexities of the FX market with greater confidence and precision.
