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. Nicolas Cary is an American businessman, best known as the co-founder of Blockchain.info and a philanthropist.

A fictional currency is some form of currency defined, or alluded to, in works of fiction.  The names of units of such currency are sometimes based on extant or historic currencies (e.g. "Altairian dollars" or "Earth yen") while other names, such as "Kalganids" in Asimov's "Foundation" series, may be wholly invented.  A particularly common type, especially in science fiction, is electronically managed "credits".  In some works of fiction, exchange media other than money are used.  These are not currency as such, but rather nonstandard media of exchange used to avoid the difficulties of ensuring "double coincidence of wants" in a barter system. A community currency is a type of complementary currency that is used by groups with a common bond, like members of a locality, or association, and designed to meet their needs.

Virtual currency, also known as virtual money, is a type of unregulated, digital money, which is issued and usually controlled by its developers, and used and accepted among the members of a specific virtual community.  The Financial Crimes Enforcement Network (FinCEN), a bureau of the US Treasury, defined virtual currency in its guidance published in 2013.  In 2014, the European Banking Authority defined virtual currency as "a digital representation of value that is neither issued by a central bank or a public authority, nor necessarily attached to a fiat currency, but is accepted by natural or legal persons as a means of payment and can be transferred, stored or traded electronically". The moving average rate procedure is a proven procedure within development cooperation to convert locally used currency of the projects (voucher currency) to the currency used at the head office (company currency). A floating exchange rate or fluctuating exchange or flexible exchange rate is a type of exchange-rate regime in which a currency's value is allowed to fluctuate in response to foreign-exchange market mechanisms.  A currency that uses a floating exchange rate is known as a floating currency.  A floating currency is contrasted with a fixed currency whose value is tied to that of another currency, material goods or to a currency basket.
