Foreign exchange risk is the risk that a business's financial performance or position such as AASB Financial Instruments: Recognition and Measurement. model the potential impact of exchange rate movements on its foreign currency.
Alternatively, it could be exposed to currency risk even if it sold only in the eurozone but with UK competitors producing in British pounds. The German brewing company exporting to the United States cannot use financial instruments to hedge the structural risk because of the size and duration of the exposure it would require hedging the full amount of dollar-denominated revenues for all future years in business.
The only effective way to reduce structural exposure is to reduce the underlying mismatch of cash flows. For example, automobile manufacturers from Germany and Japan having shifted production to the United States, thereby lowering their structural exposure to the dollar. Similarly, arranging local funding of foreign operations will mitigate structural exposure although the impact is usually limited, as financial expenses tend to be a small fraction of the total cost base.
The German brewer can only sell its beer as a premium import in the US market if it is brewed in Germany. Transaction risks. As the most visible currency risks a company faces, transaction risks are also the simplest to measure and manage.
These occur as a result of timing differences between a contractual commitment and actual cash flows. Suppose a company manufactures a product in China and sells it in the United States for a price set in dollars.
Note that downloading-power parity does not help in reducing transaction risk: Transaction risks typically affect short-term cash flows and are unlikely to put a company into financial difficulties except for extreme cases—for example, when it commits to very large downloads or sales that are fixed in a foreign currency.
Managing transaction risk is relatively straight-forward with financial instruments because each transaction is clearly definable and mostly short term. Many companies have hedging programs for their operating cash flows from foreign operations.
Companies may have good reasons for managing currency risk—for example, to facilitate planning and performance management or for tax purposes. In general, they should not manage currency risk just for the sake of lowering cash-flow volatility or boosting share price.
Shareholders are well aware of the currency risks faced by the companies they invest in and can manage any associated volatility themselves by appropriately diversifying their investment portfolio.
Furthermore, in the long term, currency fluctuations tend to be offset by price changes, thereby reducing currency risk in real terms. As academic research shows, investors therefore do not require a risk premium for bearing currency risk, and companies with lower currency risk will not experience a lower cost of capital.
See, for example, Piet Sercu, chapter 19, in International Finance: Theory into Practice , first edition, Princeton, NJ: Princeton University Press, Instead, managers should focus on those currency risks that could lead to financial disruption or distress.
Deciding how much currency risk is acceptable should be similar to deciding how much debt is acceptable: That risk appetite could be expressed as a target default probability, cash flow at risk, or simply a target coverage ratio or credit rating. Given the target, managers should identify which currency risks are acceptable and which are not. Rather than enumerating yet another set of steps, we offer instead several higher-level recommendations for managers.
Currency risks should not be managed in isolation, as they may well offset one another. For example, if a European airline were to order a Boeing aircraft, priced in dollars, for delivery a year from now, it might download the dollars it will need today or enter into a forward contract to download them in a year.
But if the airline also has long-term net cash inflows from passenger tariffs set in dollars, then that transaction hedge effectively increases, rather than decreases, its exposure to changes in the dollar.
Unfortunately, current accounting practices do not draw the attention of managers and investors to the most important types of currency risk. The most important impact of currency changes, which comes from structural risk, finds its way into the income statement through movements in revenues and costs but not as an explicit line item.
Financial instruments such as futures, swaps, and options can effectively hedge well-specified, short-term currency risks such as transaction risks. But the most important risks are often not as well specified or long term. Take the example of a US consumer-goods company exporting to China. Its cash-flow exposure to changes in the renminbi exchange rate depends on competitor actions and consumer preferences.
Moreover, since the company has made long-term investments in consumer brands and distribution channels, its exposure is large and stretched out over many years. Indeed, the size and duration of such risks make it impossible to effectively hedge with financial instruments. In some cases, hedging short-term structural risks can download time for management to react with operational or strategic measures, such as renegotiating pricing contracts, finding opportunities for cost reductions, or relocating production.
For example, airlines can hedge their fuel costs, but such a move is only effective for about 12 to 18 months. That reprieve can secure cash flows for fixed commitments, giving airlines time to cut costs or raise prices to respond to fuel-price changes.
Companies today often describe their currency-hedging strategy in detail in their financial reports. Unfortunately, these strategies mainly address transaction or short-term structural risks and fail to provide shareholders any real insights into the type and size of long-term structural risks a company faces—or which of them it actively manages and why.
And they often focus on the accounting impact of currency risk and their efforts to mitigate it rather than the impact on cash flow. Investors are better off when companies report the past impact of currency fluctuations on their operating earnings or, even better, on their operating cash flow. If relevant, this disclosure could be by business segment and by currency. Philips, for example, discloses key factors affecting its operating earnings, including currency changes.
Ideally, this would be followed by an estimate of how the exchange rate would affect future revenues and operating profits.
Alcoa includes estimates of the sensitivity of its net income to changes in five major exchange rates Exhibit 2. This would also fit with best practice in forward revenue and earnings guidance: It is surprising how few large international companies explain their key assumptions underlying forward guidance—an easy way to discuss risks and uncertainties with shareholders.
Companies are susceptible to a range of currency risks, but not all of them are risks they can or should try to manage. Forward contracts are mutual agreements to deliver a certain amount of a commodity at a certain date for a specified price and each contract is unique to the downloader and seller. For this example, the farmer can sell a number of forward contracts equivalent to the amount of wheat he expects to harvest and essentially lock in the current price of wheat. Once the forward contracts expire, the farmer will harvest the wheat and deliver it to the downloader at the price agreed to in the forward contract.
Therefore, the farmer has reduced his risks to fluctuations in the market of wheat because he has already guaranteed a certain number of bushels for a certain price. However, there are still many risks associated with this type of hedge. For example, if the farmer has a low yield year and he harvests less than the amount specified in the forward contracts, he must download the bushels elsewhere in order to fill the contract.
This becomes even more of a problem when the lower yields affect the entire wheat industry and the price of wheat increases due to supply and demand pressures. Also, while the farmer hedged all of the risks of a price decrease away by locking in the price with a forward contract, he also gives up the right to the benefits of a price increase. Another risk associated with the forward contract is the risk of default or renegotiation. The forward contract locks in a certain amount and price at a certain future date.
Because of that, there is always the possibility that the downloader will not pay the amount required at the end of the contract or that the downloader will try to renegotiate the contract before it expires. Future contracts are another way our farmer can hedge his risk without a few of the risks that forward contracts have.
Future contracts are similar to forward contracts except they are more standardized i. These contracts trade on exchanges and are guaranteed through clearinghouses. Clearinghouses ensure that every contract is honored and they take the opposite side of every contract.
Future contracts typically are more liquid than forward contracts and move with the market. Because of this, the farmer can minimize the risk he faces in the future through the selling of future contracts. Future contracts also differ from forward contracts in that delivery never happens. The exchanges and clearinghouses allow the downloader or seller to leave the contract early and cash out.
So tying back into the farmer selling his wheat at a future date, he will sell short futures contracts for the amount that he predicts to harvest to protect against a price decrease. The current spot price of wheat and the price of the futures contracts for wheat converge as time gets closer to the delivery date, so in order to make money on the hedge, the farmer must close out his position earlier than then.
On the chance that prices decrease in the future, the farmer will make a profit on his short position in the futures market which offsets any decrease in revenues from the spot market for wheat.
On the other hand, if prices increase, the farmer will generate a loss on the futures market which is offset by an increase in revenues on the spot market for wheat. Instead of agreeing to sell his wheat to one person on a set date, the farmer will just download and sell futures on an exchange and then sell his wheat wherever he wants once he harvests it.
A stock trader believes that the stock price of Company A will rise over the next month, due to the company's new and efficient method of producing widgets.
He wants to download Company A shares to profit from their expected price increase, as he believes that shares are currently underpriced. But Company A is part of a highly volatile widget industry. So there is a risk of a future event that affects stock prices across the whole industry, including the stock of Company A along with all other companies.
Since the trader is interested in the specific company, rather than the entire industry, he wants to hedge out the industry-related risk by short selling an equal value of shares from Company A's direct, yet weaker competitor , Company B.
The first day the trader's portfolio is:. If the trader was able to short sell an asset whose price had a mathematically defined relation with Company A's stock price for example a put option on Company A shares , the trade might be essentially riskless.
In this case, the risk would be limited to the put option's premium. On the second day, a favorable news story about the widgets industry is published and the value of all widgets stock goes up. The trader might regret the hedge on day two, since it reduced the profits on the Company A position. But on the third day, an unfavorable news story is published about the health effects of widgets, and all widgets stocks crash: Nevertheless, since Company A is the better company, it suffers less than Company B:.
The introduction of stock market index futures has provided a second means of hedging risk on a single stock by selling short the market, as opposed to another single or selection of stocks. Futures are generally highly fungible and cover a wide variety of potential investments, which makes them easier to use than trying to find another stock which somehow represents the opposite of a selected investment.
Employee stock options ESOs are securities issued by the company mainly to its own executives and employees. These securities are more volatile than stocks. An efficient way to lower the ESO risk is to sell exchange traded calls and, to a lesser degree, [ clarification needed ] to download puts. Companies discourage hedging the ESOs but there is no prohibition against it. Airlines use futures contracts and derivatives to hedge their exposure to the price of jet fuel.
They know that they must download jet fuel for as long as they want to stay in business, and fuel prices are notoriously volatile. By using crude oil futures contracts to hedge their fuel requirements and engaging in similar but more complex derivatives transactions , Southwest Airlines was able to save a large amount of money when downloading fuel as compared to rival airlines when fuel prices in the U.
As an emotion regulation strategy, people can bet against a desired outcome. A New England Patriots fan, for example, could bet their opponents to win to reduce the negative emotions felt if the team loses a game. People typically do not bet against desired outcomes that are important to their identity, due to negative signal about their identity that making such a gamble entails.
Betting against your team or political candidate, for example, may signal to you that you are not as committed to them as you thought you were. Hedging can be used in many different ways including foreign exchange trading. The stock example above is a "classic" sort of hedge, known in the industry as a pairs trade due to the trading on a pair of related securities.
As investors became more sophisticated, along with the mathematical tools used to calculate values known as models , the types of hedges have increased greatly. Examples of hedging include: A hedging strategy usually refers to the general risk management policy of a financially and physically trading firm how to minimize their risks. As the term hedging indicates, this risk mitigation is usually done by using financial instruments , but a hedging strategy as used by commodity traders like large energy companies, is usually referring to a business model including both financial and physical deals.
In order to show the difference between these strategies, let us consider the fictional company BlackIsGreen Ltd trading coal by downloading this commodity at the wholesale market and selling it to households mostly in winter. Back-to-back B2B is a strategy where any open position is immediately closed, e. If BlackIsGreen decides to have a B2B-strategy, they would download the exact amount of coal at the very moment when the household customer comes into their shop and signs the contract.
This strategy minimizes many commodity risks , but has the drawback that it has a large volume and liquidity risk , as BlackIsGreen does not know how whether it can find enough coal on the wholesale market to fulfill the need of the households. Tracker hedging is a pre-download approach, where the open position is decreased the closer the maturity date comes. If BlackIsGreen knows that most of the consumers demand coal in winter to heat their house.
A strategy driven by a tracker would now mean that BlackIsGreen downloads e.
The closer the winter comes, the better are the weather forecasts and therefore the estimate, how much coal will be demanded by the households in the coming winter. A certain hedging corridor around the pre-defined tracker-curve is allowed and fraction of the open positions decreases as the maturity date comes closer.
Delta-hedging mitigates the financial risk of an option by hedging against price changes in its underlying. It is called like that as Delta is the first derivative of the option's value with respect to the underlying instrument 's price. This is performed in practice by downloading a derivative with an inverse price movement. It is also a type of market neutral strategy.
Only if BlackIsGreen chooses to perform delta-hedging as strategy, actual financial instruments come into play for hedging in the usual, stricter meaning. Risk reversal means simultaneously downloading a call option and selling a put option.
This has the effect of simulating being long on a stock or commodity position. Many hedges do not involve exotic financial instruments or derivatives such as the married put. A natural hedge is an investment that reduces the undesired risk by matching cash flows i. For example, an exporter to the United States faces a risk of changes in the value of the U.
Another example is a company that opens a subsidiary in another country and borrows in the foreign currency to finance its operations, even though the foreign interest rate may be more expensive than in its home country: Similarly, an oil producer may expect to receive its revenues in U. One common means of hedging against risk is the download of insurance to protect against financial loss due to accidental property damage or loss, personal injury, or loss of life.
There are varying types of financial risk that can be protected against with a hedge. Those types of risks include:. Equity in a portfolio can be hedged by taking an opposite position in futures.
To protect your stock picking against systematic market risk , futures are shorted when equity is downloadd, or long futures when stock is shorted. One way to hedge is the market neutral approach. In this approach, an equivalent dollar amount in the stock trade is taken in futures — for example, by downloading 10, GBP worth of Vodafone and shorting 10, worth of FTSE futures the index in which Vodafone trades.
Another way to hedge is the beta neutral. Beta is the historical correlation between a stock and an index.
Futures contracts and forward contracts are means of hedging against the risk of adverse market movements. These originally developed out of commodity markets in the 19th century, but over the last fifty years a large global market developed in products to hedge financial market risk.
