Businesses that operate internationally often face the challenge of fluctuating currency exchange rates. These fluctuations can impact their profitability when they need to pay or receive money in foreign currencies. To mitigate this risk, they can use a financial tool called an Average Rate Option (ARO). This article will explain what AROs are, how they work, their benefits and risks, and who uses them.
What is an Average Rate Option?
An ARO is a type of foreign exchange (FX) derivative. It’s designed to act as a hedge against unfavorable changes in currency values. Instead of using a fixed exchange rate, an ARO uses an average exchange rate calculated over a specific period. The “strike price” for this option isn’t fixed upfront; it is determined by averaging the spot exchange rates during the life of the option. This means the buyer will receive a cash payout if the average exchange rate is more favorable than the strike price at the expiry date. If the average rate is equal to or worse than the strike rate, the option expires with no value.
How AROs Function: A Simplified Explanation
Imagine a business that needs to make regular payments in a foreign currency. Here’s a breakdown of how an ARO would work:
- Agreement: The business (the buyer) enters into an ARO contract with a seller, agreeing on a specific currency pair, a payment schedule, and a strike price mechanism.
- Premium: The buyer pays a premium to the seller for the right to use the option.
- Payment Period: The buyer makes their regular foreign currency payments in the open market during the defined period.
- Expiry: At the maturity date, the average rate paid during the contract period is calculated. This is compared to the strike rate that was determined at the expiry.
- Settlement: If the calculated average exchange rate is less favorable than the strike price, the seller will pay the difference to the buyer. If it is equal to or more favorable than the strike rate, the option expires with no payout.
Why Are AROs Called “Exotic” and “European”?
Due to their fluctuating strike price, AROs are referred to as exotic options, setting them apart from standard options. They’re also classified as European options because the ability to exercise the option is limited to the contract’s expiry date.
Who Benefits from Average Rate Options?
Businesses that regularly engage in international transactions and have to deal with multiple currencies are the primary users of AROs. These businesses are vulnerable to currency fluctuations that can affect their profit margins.
Example: A U.S. company buying raw materials from China and paying in yuan is a perfect example. AROs allow the US company to set a “worst-case” exchange rate scenario, protecting themselves against a weakening dollar.
Benefits of Average Rate Options
- Protection against unfavorable FX movements: AROs safeguard against negative currency fluctuations that result in unfavorable exchange rates compared to the agreed strike price.
- Worst-case rate: Businesses can effectively calculate the worst-case exchange rate for their transactions.
- Potential for profit: If currency fluctuations are advantageous, businesses still benefit.
- Flexibility: AROs can be sold in the spot market if the need for the option no longer exists.
Risks Associated with Average Rate Options
- Premium cost: The initial premium paid for the option is non-refundable and is lost if the option expires worthless.
- Depreciation of value: The option’s value can decrease as it approaches maturity.
- Limited Refund: If the option is terminated before the expiry, there may be limited to no refund of the initial cost.
Beyond Currency: Other Average Options
It’s worth noting that averaging is not limited to currency options. Average Strike Options can be used to manage price volatility in various assets like stocks over a specified period.
Who Uses AROs?
AROs are not traded on any regulated stock exchange. They are generally considered an institutional financial instrument, making them a common choice for larger investors looking to manage risk. Due to their complex nature, AROs are generally not used by individual retail investors.
Conclusion
Average Rate Options provide a valuable tool for businesses to manage foreign exchange risk and protect their bottom line. While they have costs and risks, they can be beneficial when used as part of a comprehensive risk management strategy. This explanation should give you a basic understanding of what AROs are and why they are used in the global financial landscape.
