CORPORATE FX RISK:
IDENTIFICATION, MEASUREMENT AND MANAGEMENT
by Ang Thiam Huat, Honorary
Secretary, Association of Corporate Treasure, Singapore
Foreign
Exchange Risk is regarded as the effect that unanticipated exchange rate
changes have on the value of the firm. Currency fluctuations will impact upon a
firm's business, cash flows and value of its assets and liabilities.
Consequently, foreign exchange risks must be Identified, Measured and Managed.
How
do we measure the currency exposures? Exposures are usually classified under
transactional, translation and economic exposures. Every firm's exposure
differs given the nature of its commercial transactions and geographical
coverage. Ultimately the decision as to the set of most effective and efficient
instruments and techniques for the firm would depend on how well the firm's
financial and economic interests are protected and enhanced.
The
availability of Foreign exchange products depends on the location the firm is
operating from, and the currency regime it operates under. Broadly speaking in
international financial markets, hedging alternatives ranges from the choice of
currency of debts and assets, currency spot, forwards, futures, swaps, options,
exotic options and structured products.
What is Foreign Exchange Risk?
Foreign
Exchange Risk is a potential gain or loss that occurs from unanticipated change
in foreign exchange rate. At an individual level, if a Chinese national owns
IBM stocks denominated in USD, the USD/RMB exchange rate is then of great
interest to this investor. After all, the relevant returns measure is in RMB,
since he is a PRC resident. In other words, the basic objective of any entity
must be to at least preserve purchasing power, be it from a local or
international perspective.
One
may think that a PRC company that procures raw material locally, manufactures
and sells locally does not have to face currency risks. But it does. If over
time the RMB strengthens against foreign currencies, the relative
competitiveness of PRC firms viz-a-viz foreign firms may encourage foreign
firms selling more into the PRC market. It is likely that market share and
sales volumes would also change given the RMB exchange rate dynamics.
Often
besides contractual cash flows, companies also hedge anticipated cash flows.
The key is to judge the level of certainty as to the anticipated cash flows.
Companies with long business experience are likely to be able to gauge their
raw material, sales volumes in various currencies quite well. As to how far out
in time should these anticipated cash flows be based upon, this issue is
company specific and depends on how confident the firm is in terms of the
accuracy of the projections.
Difficulties Faced In Managing Foreign Exchange Risk
Many
firms refrain from active management of their foreign exchange exposure, even
though they understand that exchange rate fluctuations can affect their
earnings and value. They hold this view for a number of reasons.
The
management team may not fully understand financial markets and instruments.
They may view the use of risk management products, such as forwards, futures,
swaps and options, as speculative. A lack of understanding and news of
financial scandals further add to the fear of financial products. Such fears
are unwarranted, since financial risks is inherent in the commercial activities
and putting on hedges simply neutralizes the risks.
Currency
exposure is often complex and difficult to measure. Despite such difficulties,
businesses should continue to improve on their foreign exchange processes and
not throw up their hands in despair. It is important to train our colleagues in
the commercial department as to the importance of foreign exchange management
and the need for good commercial forecasts.
From
a transactional perspective, foreign currency receivables and payables may be
hedged, but foreign exchange rate movements will invariably affect the business
competitiveness of the firm.
Some
suggest that there are economic justifications for firms to do nothing about
their foreign exchange risk. They believe that firms cannot improve shareholder
value by financial manipulations and that investors can hedge corporate exchange
exposure by taking out forward contracts in accordance with their ownership in
a firm. This of course is not how the real world works, since investors are not
privy to the firms' operational exposures, let alone putting on hedges to
neutralize the exposures. Some very large multinationals however take the view
that since they are exposure in a wide range of currencies worldwide,
appreciation in some currencies and depreciation in others would even out the
profit and loss effect, and as such they choose not to hedge. By not hedging
they also save on the transactions cost of putting on the hedges. There aren't
many such firms.
Identifying Foreign Exchange Exposure
It
is in the best interest of the firm and its shareholders to ensure that
corporate foreign exchange risk is managed well. It is important to identify
the nature and magnitude of the firm's foreign exchange exposures.
Firms
have receivables, payables, inventories, plant and equipment and other tangible
assets in various countries. To gauge impact of exchange rate changes on a
firm, we need to measure its exposure or the amount at risk by looking at
future cash flows and their associated risk profiles.
Tools and Techniques for the Management of Foreign Exchange Risk
Let
us consider the relative features and merits of several different foreign
exchange products used for hedging exchange risk, including forwards, futures,
debt, swaps and options. Most foreign exchange products enable the firm to take
a long or a short position to hedge an opposite short or long position which
resulted from a commercial transaction. The cost of these instruments may
differ in terms of default risk or transactions costs.
Foreign
Exchange Forwards
The
forward rate is a price for foreign currency set at the time of the transaction
but with delivery taking place at a specified future date. While the
transaction amount, the value date, the payments procedure, and the exchange
rate are all determined in advance, no exchange of money takes place until the
actual settlement date. This commitment to exchange currencies at a previously
agreed exchange rate is a forward contract.
Forward
contracts are the most common means of hedging transactions in foreign
currencies. As the timing of commercial requirement changes, forward contracts
can be rolled forward or backward to dovetail into the commercial requirement.
Forward contracts require future performance and subject to counter-party
risks. If the counter-party is unable to perform on the contract, the hedge
disappears and it could be at great cost to the hedger.
Currency
Futures
Outside
of the inter-bank forward market, the best-developed market for hedging
exchange rate risk is the currency futures market. In principle, currency
futures are similar to foreign exchange forwards in that they are contracts for
delivery of a certain amount of a foreign currency at some future date and at a
known price. In practice, they differ from forward contracts in important ways.
One difference between forwards and futures is standardization.
Forwards
are for any amount the counter-party is willing to quote. Futures are traded in
standard amounts, each contract being far smaller than the average forward
transaction. Futures are also standardized in terms of delivery date. The
normal currency futures delivery dates are March, June, September and December,
while forwards are private agreements that can specify any delivery date that
the parties agree on.
Another difference is that forwards are
traded by phone and through internet FX portals and are completely independent
of location or time. Futures, on the other hand, are traded in organized
exchanges.
But
the most important feature of the futures contract is not its standardization
or trading organization but in the time pattern of the cash flows between
parties to the transaction. In a forward contract, whether it involves full
delivery of the two currencies or just compensation of the net value, the
transfer of funds takes place once at maturity. With futures, cash changes
hands every day during the life of the contract, or at least every day that has
seen a change in the price of the contract. This daily cash compensation or
margining feature largely eliminates default risk.
Thus
forwards and futures serve similar purposes, and tend to have identical rates,
but differ in their applicability. Most big companies would use forwards;
futures tend to be used whenever credit or counter-party risk may be an issue.
Use
of Debt instead of Forwards or Futures
Borrowing
in the currency to which the firm has exposure in or investing in
interest-bearing assets to offset a foreign currency payment is a widely used
hedging tool that serves much the same purpose as forward contracts.
For
example instead of selling USD receivables forward, we can borrow USD and
convert into EUR in the spot market, and holding EUR in deposit for say, two
months. When payment in USD is received from the customer, the USD proceed is
used to pay down the USD debt. Such a transaction is termed a money market
hedge.
The
cost of this money market hedge is the difference between the USD interest rate
paid and the EUR interest rate earned. According to the interest rate parity
theorem, the interest differential equals the forward exchange premium or
discount, the percentage by which the forward rate differs from the spot
exchange rate. The cost of the money market hedge should be the same as the
forward or futures market hedge. In practice, the forward market is usually
more efficient than a money market hedge, as there are heftier spreads in the
loan and deposit markets.
Currency
Options
Many
companies use forward FX contracts extensively. With a forward contract one can
lock in an exchange rate for the future. There are a number of circumstances, however,
where it may be desirable to have more flexibility than a forward provides.
A
foreign exchange option is a contract for future delivery of a currency in
exchange for another, where the holder of the option has the right to buy (or
sell) the currency at an agreed price, but is not required to do so. For such a
right he pays a price called the option premium. The option seller receives the
premium and is obliged to make (or take) delivery at the agreed-upon price if
the buyer exercises his option.
Futures
and forwards are contracts in which two parties oblige themselves to exchange
currencies in the future. They are thus useful to hedge or convert known
currency exposures. Options, in contrast, provide the only convenient means of
hedging or taking position in volatility risk.
Unmanaged
exchange rate risk can cause significant fluctuations in the earnings and the
market value of an international firm. At some level, the currency change may
threaten the firm's viability, bringing the costs of bankruptcy to bear. To
avert this, it may be worth buying some low-cost options that would pay off
only under unusual circumstances that would particularly hurt the firm.
Controlling
Corporate Treasury Trading Risks
In
a company it is difficult to ensure that every risk is perfectly hedged. Not
every transaction can be matched, international trade and production are both
complex and uncertain. Flexibility is called for, and management must
necessarily give discretion to the corporate treasury department in charged of
managing foreign exchange risks. However, limits must be imposed on the trading
activities of the corporate treasury, losses can get out of control even in the
best companies.
Management
must elucidate the goals of exchange risk management in operational terms. The
risks of in-house trading must be recognized. These include losses on open
positions from exchange rate changes, counterparty credit risks, and operations
risks. For all net positions taken, the firm must have an independent method of
valuing and marking-to-market the financial instruments traded. This is
necessary to prevent the hiding of losses. Wherever possible, marking to market
should be based on external, objective prices traded in the market. As in all
these things, any attempt to cover up losses should be severely penalized.
Finally,
counterparty risks resulting from over-the-counter forward or swap contracts
should be evaluated in precisely the same manner as is done when the firm
extends credit to customers.
