What is the purpose of a currency swap?

In the case of swaps being made by businesses and institutions the reason currency swaps are done is typically as a hedge, or as a way to get cheaper financing. In the investing world a currency swap might be sought after by buying a high-yielding currency such as the Australian dollar, while simultaneously selling a low yielding currency like the Japanese Yen. So long as the movement in the pair is flat or advantageous to the trader, they can continue holding the pair while also collecting the swap, or the difference in interest rates between the two currencies.

What's the greatest advantage of currency swaps for investors?

While using a currency swap as a way to generate income can be useful, the greatest advantage of a currency swap for retail investors is the ability to hedge against volatility in the currency markets. With a currency swap an investor can reduce the volatility in their overseas holdings, thus improving their risk-return profile and smoothing out the ups and downs in their portfolio. Because currency rates are always changing currency swaps can help to smooth out profits and losses in any portfolio.

What are the potential downsides to currency swaps?

There are a few negatives that can also be associated with currency swaps. In the case of an investor hedging their position, any positive movement in the currency will be muted in the results of the investment because the hedge is protecting from volatility in both directions. Those holding a position to collect the swap (such as AUD/JPY) could get wiped out by a sudden adverse movement in the currency pair. In the case of businesses doing swaps there is a credit and interest rate risk, particularly with swaps that stretch over several years.

What is a Cross Currency Swap?

A currency swap, or a cross-currency swap, is a contract between two parties to exchange interest payments and principal amounts in two different currencies at a pre-agreed rate of exchange. So, how does currency swap work? At the outset of the contract, the two parties exchange specific amounts of two currencies, and they then repay them according to a pre-agreed structure. Although considered derivatives, currency swaps are not used for speculation; rather they are utilised to lock in a fixed exchange rate or hedge against fluctuations. The payable interest rates are highly customisable. That is, they can be fixed, variable, or even both.

Types of Cross Currency Swaps

There are two main types of cross-currency swaps: exchange of principal and exchange of interest. In the first case, two companies exchange principal amounts that determine their desired or agreed rate of foreign exchange. Let us look at a currency swap example here. A US Company A agrees to give a UK Company B $15,000,000 in exchange for £10,000,000. This effectively means that the GBPUSD exchange rate is or has been set at 1.5000. At the end of the contract length, the companies will pay back the principal amounts they owe each other. This will protect both companies from the risk of exchange rate fluctuations. However, both companies can agree to pay each other some interest rate values when the forex rate substantially changes during the life of the contract.

In the second case, two parties agree to exchange their interest rate payments obligations on underlying loans. There is no principal exchanged at the outset, and the two parties are in a legally binding contract independent of the underlying lenders. The interest rate payments can be fixed or variable. Companies can agree to exchange interest rate payments to reduce the cost of borrowing or to guard against other uncertainties related to the underlying principal amount.

Currency Swaps Explained

In finance, a currency swap, also known as cross-currency swap, is a legal contract between two parties to exchange two currencies at a later date, but at a predetermined exchange rate. Usually, global banks operate as the facilitators or middlemen in a currency swap deal; but they can also be counterparties in currency swaps as a way to hedge against their global exposure, particularly to foreign exchange risk.

Benefits of Currency Swaps

Currency swaps have always been very convenient in finance. They allow for the redenomination of loans or other payments from one currency to the other. This comes with various advantages for both individuals and companies. There is the flexibility to hedge the risk associated with other currencies as well as the benefit of locking in fixed exchange rates for a longer period of time. For large corporations, currency swaps offer the unique opportunity of raising funds in one particular currency and making savings in another. The risk for performing currency swap deals is very minimal, and on top of that, currency swaps are very liquid, and parties can settle on an agreement at any time during the lifetime of a transaction. Early termination of a currency swap deal is also possible through negotiation between the parties involved.

Real-World Examples of Currency Swaps

IBM–World Bank Swap (1981)

Significance: Demonstrated how two parties with complementary needs could reduce borrowing costs via a currency swap.

Federal Reserve Central Bank Swap Lines (2007–2009; 2020)

Mechanics: The Fed provided USD to these central banks in exchange for their local currency, which was swapped back at maturity at the same exchange rate, plus interest.
Impact: Helped stabilise global dollar funding markets and reduce volatility.

China’s Renminbi Swap Agreements

Overview: The People’s Bank of China (PBoC) has entered into multiple bilateral currency swap arrangements with countries such as Argentina, Indonesia, and Russia.

Corporate Hedging Examples

Apple Inc. (Various Years): Uses currency swaps to hedge exposures in EUR, GBP, JPY, etc., given its global sales distribution.
Toyota Motor Corporation (2015): Entered into cross-currency swaps to manage interest costs on USD-denominated bonds while keeping net exposure in JPY.

Forex Swap

In online forex trading, a swap is a rollover interest that you earn or pay for holding your positions overnight. The swap charge depends on the underlying interest rates of the currencies involved, and whether you are long or short on the currency pair involved. If you open and close a trade within the same day, swap interest will not apply. Some of the high (positive) yielding currencies in forex include the Australian dollar (AUD) and New Zealand dollar (NZD); while low (negative) yielding currencies include the Japanese yen (JPY) and the euro (EUR). Basically, if you buy a high yielding currency against a low yielding one, you will earn positive swap interest, but note that it can also go the other way around. There’s an option to avoid swaps whatsoever by opening a swap-free Islamic trading account.
