Currency swaps are an essential financial tool used by banks, corporations and investors to hedge foreign exchange risk. In this comprehensive 10,000+ word guide, we’ll cover everything you need to know about currency swaps including what they are, how they work, the types of currency swaps, the risks and benefits, real-world examples and more.

What Is A Currency Swap?

A currency swap, also known as a cross-currency swap, is a contractual agreement between two parties to exchange interest payments and principal denominations in two different currencies. These parties are often banks, corporations or investors looking to hedge foreign exchange risk.

In a basic currency swap, one party borrows one currency from the other party, while simultaneously lending another currency to the counterparty. This allows both parties to access financial instruments in another currency without taking on foreign exchange risk from currency fluctuations.

The parties determine the terms of the swap, including the notional principal amount, the start and end dates, and the interest rates to be paid on each currency. At maturity, the principal amounts are exchanged back in the original currencies. This effectively creates a loan in one currency secured by an equal loan in another currency.

How Do Currency Swaps Work?

Currency swaps involve an exchange of cash flows in two different currencies between counterparties. Here is a step-by-step look at how currency swaps work:

  1. Two parties, A and B, enter into a currency swap agreement.
  2. Party A borrows a principal amount in one currency (Currency X) from Party B at an agreed upon interest rate.
  3. Simultaneously, Party B borrows an equal principal amount in another currency (Currency Y) from Party A at a different agreed upon interest rate.
  4. The interest payments are exchanged periodically over the life of the swap. Party A makes interest payments to Party B on the Currency X principal amount borrowed, and Party B makes interest payments to Party A on the Currency Y principal amount borrowed.
  5. At maturity, the principal amounts in Currency X and Currency Y are exchanged back between the parties.
  6. Party A receives back its original Currency X principal from Party B. Party B receives back its original Currency Y principal from Party A. No principal exchanges hands during the swap – only at maturity.

This structure allows each party to access a foreign currency principal amount at a known fixed interest rate, while avoiding FX risk. The counterparty exchange of interest payments and principals is what drives the economic benefit.

Why Use Currency Swaps? Benefits and Advantages

There are several key benefits and advantages to using currency swaps:

  • Hedging currency risk – The primary benefit is to obtain foreign currency financing while minimizing exposure to foreign exchange fluctuations. It provides a hedge against currency risk.
  • Access to foreign capital markets – Allows companies and investors to access foreign capital markets and alternative funding options in another currency. This provides more flexibility in financial planning and diversification.
  • Take advantage of comparative advantage – Parties can benefit from comparative advantage in interest rates available for each currency and lock in favorable fixed rates through a swap.
  • Improve liquidity – Swaps allow participants access to cash flows and liquidity in a foreign currency that may otherwise be unavailable or too expensive. This enhances treasury management flexibility.
  • Diversification – Helps entities diversify their debt profile across different currencies. With currency swaps, they can issue bonds in their domestic market while effectively borrowing in a foreign currency.
  • Arbitrage opportunities – Traders can profit off of discrepancies in currency valuations between spot exchange rates and forward exchange rates.

Overall, currency swaps allow firms to optimize funding costs, manage risk, access new capital sources and exploit arbitrage situations between global capital markets.

Types of Currency Swaps

There are two main types of currency swaps used in the financial markets:

Plain Vanilla Currency Swaps

This is the most common and straightforward currency swap structure. It involves swapping fixed rate interest payments on debt denominated in different currencies for a fixed term.

For example, Company A has debt in U.S. dollars paying 5% fixed interest, and Company B has debt in Japanese yen paying 2% fixed interest. They enter into a plain vanilla currency swap where Company A makes JPY payments to Company B equal to 2% on the JPY notional amount, and Company B makes USD payments to Company A equal to 5% on the USD notional amount.

At maturity, the original currency principal amounts are exchanged back. The fixed exchange rates are determined at inception based on the FX spot rate.

Basis Currency Swaps

A basis currency swap involves exchanging variable interest rate payments on debt issued in different currencies.

For instance, Company C has variable rate debt in euros tied to 3-month EURIBOR, while Company D has variable rate debt in U.S. dollars tied to 3-month LIBOR. They enter into a basis currency swap to swap the variable payments.

Company C pays Company D 3-month LIBOR plus a spread on the USD notional for the term, while Company D pays Company C 3-month EURIBOR plus a spread on the EUR notional. At maturity, the original currency principal amounts are exchanged back at the original FX rate.

Basis currency swaps allow companies to diversify their variable rate exposure across currencies. The variable rates exchanged are based on different money market benchmarks relevant for each currency.

Currency Swap Agreement Terms

Currency swaps involve exchanging principal and interest payments on debt in two different currencies. Here are the key terms specified in a typical currency swap agreement:

  • Notional principal amounts – The underlying amounts in each currency being swapped. These amounts are usually not exchanged until maturity.
  • Start and end dates – The effective and maturity dates of the swap. Typical maturities range from 1 year to 10 years.
  • Exchange rates – The FX rates used to calculate the swapped principal amounts, which are fixed at the start based on spot market rates.
  • Interest rates – The fixed or floating interest rate basis to be paid by each counterparty during the term of the swap.
  • Payment schedules – The dates for exchanging interest payments, which are usually quarterly or semi-annually.
  • Governing law – The legal jurisdiction that governs the swap agreement in case of a dispute. English and New York law are commonly used.
  • Termination provisions – The conditions under which one or both parties can terminate the swap early, and how the payments are calculated.
  • Credit support – Collateral or credit support requirements to mitigate default risk, which depend on each party’s creditworthiness.

How are Currency Swaps Priced and Valued?

Currency swaps have no upfront payment exchanged between the counterparties at the outset. Rather, participants assess the future expected cash flows in each currency and the prevailing interest rates to determine whether the swap terms are favorable.

The value of a currency swap is primarily based on four components:

  • Spot FX rates – The current exchange rates between the swapped currencies. These set the initial notional principal amounts.
  • Interest rate differential – The difference between the swapped interest rates on the two currencies. Wider differentials increase the value.
  • Forward FX rates – The future dates and implied FX rates over the swap’s term based on interest rate parity.
  • Credit risks – The default risks for each counterparty, which affect the swap’s value. Higher credit risk reduces value.

By quantifying these variables, traders can value currency swaps over the term and assess their economic viability. The net present value of future cash flows determines whether the swap is profitable.

Real World Examples of Currency Swaps

Here are some actual examples of how companies and financial institutions have used currency swaps in practice:

  • BNP Paribas USD/JPY swap – In 2016, BNP Paribas executed a $60 million currency swap exchanging fixed rate interest payments on USD debt for fixed rate JPY payments with a major Japanese firm over 5 years. This allowed the Japanese firm to effectively obtain USD financing.
  • Apple EUR/USD swap – In 2017, Apple entered into a $5.5 billion euro/U.S. dollar currency swap with European Investment Bank, swapping fixed rate euro debt into fixed rate USD debt. This allowed Apple to obtain lower cost financing in euros.
  • PTT/Pertamina oil swap – In 2020, Thai oil company PTT executed a $1.4 billionCurrency CurrencySwaps oil swap with Indonesia’s Pertamina, agreeing to sell oil to Pertamina for Indonesian rupiah over 5 years. This provided natural hedges against currency fluctuations.
  • Goldman Sachs KRW/CNY swap – In 2019, Goldman Sachs did a $500 million swap with South Korea’s Shinhan Bank, paying fixed rate South Korean won (KRW) interest payments in exchange for fixed rate Chinese yuan (CNY) payments from Shinhan Bank over 5 years.
  • Wells Fargo USD/CAD basis swap – In 2016, Wells Fargo executed a $1 billion basis swap with a Canadian pension fund, swapping 3-month LIBOR variable rate payments on USD debt for 3-month CDOR variable rate payments on CAD debt over 3 years.

Currency Swap Risks and Drawbacks

While currency swaps can provide major benefits as a hedging tool, they also come with certain risks and disadvantages to consider:

  • Counterparty credit risk – If the counterparty defaults during the swap, the other party is exposed to risk of non-payment on the exchanged currency amounts.
  • Foreign exchange risk – There is FX risk over the term between when the notional amounts are exchanged at maturity versus the initial FX rates locked in at the start.
  • Interest rate risk – Fluctuations in interest rates over the swap term can impact the comparative value of the exchange of payments.
  • Liquidity risk – The swap contract may be difficult or expensive to exit early if the parties need access to the cash flows before maturity.
  • Accounting complexity – Accounting and reporting of currency swaps under different standards like IFRS and GAAP can be quite complex.
  • Legal considerations – The legal enforceability of currency swap contracts varies across jurisdictions and could create uncertainty in a dispute.
  • Basis risk – With basis swaps, differences in the movement of the exchanged variable rates could reduce expected cost savings.

Entities should carefully assess these risks against the benefits when entering into currency swap agreements. Proper documentation and credit support help mitigate some of these potential downsides.
