Foreign exchange risk (also known as FX risk, exchange rate risk or currency risk) is a financial risk that exists when a financial transaction is denominated in a currency other than that of the base currency of the company. Foreign exchange risk also exists when the foreign subsidiary of a firm maintains financial statements in a currency other than the reporting currency of the consolidated entity. The risk is that there may be an adverse movement in the exchange rate of the denomination currency in relation to the base currency before the date when the transaction is completed. Investors and businesses exporting or importing goods and services or making foreign investments have an exchange rate risk which can have severe financial consequences; but steps can be taken to manage (i.e., reduce) the risk.
A firm has transaction exposure whenever it has contractual cash flows (receivables and payables) whose values are subject to unanticipated changes in exchange rates due to a contract being denominated in a foreign currency. To realize the domestic value of its foreign-denominated cash flows, the firm must exchange foreign currency for domestic currency. As firms negotiate contracts with set prices and delivery dates in the face of a volatile foreign exchange market with exchange rates constantly fluctuating, the firms face a risk of changes in the exchange rate between the foreign and domestic currency. It refers to the risk associated with the change in the exchange rate between the time an enterprise initiates a transaction and settles it.
Applying public accounting rules causes firms with transactional exposures to be impacted by a process known as "remeasurement". The current value of contractual cash flows are remeasured at each balance sheet date. If the value of the currency of payment or receivable changes in relation to the firm's base or reporting currency from one balance sheet date to the next, the expected value of these cash flows will change. U.S. accounting rules for this process are specified in ASC 830, originally known as FAS 52. Under ASC 830, changes in the value of these contractual cash flows due to currency valuation changes will impact current income.
A firm has economic exposure (also known as forecast risk) to the degree that its market value is influenced by unexpected exchange rate fluctuations. Such exchange rate adjustments can severely affect the firm's market share position with regards to its competitors, the firm's future cash flows, and ultimately the firm's value. Economic exposure can affect the present value of future cash flows. Any transaction that exposes the firm to foreign exchange risk also exposes the firm economically, but economic exposure can be caused by other business activities and investments which may not be mere international transactions, such as future cash flows from fixed assets. A shift in exchange rates that influences the demand for a good in some country would also be an economic exposure for a firm that sells that good. Economic Exposures cannot be hedged as well due to limited data, and it is costly and time-consuming. Economic Exposures can be managed by, product differention, pricing, branding, outsourcing, etc.
