Foreign exchange reserves

Foreign exchange reserves (also called forex reserves or FX reserves) are cash and other reserve assets such as gold held by a central bank or other monetary authority that are primarily available to balance payments of the country, influence the foreign exchange rate of its currency, and to maintain confidence in financial markets. Reserves are held in one or more reserve currencies, nowadays mostly the United States dollar and to a lesser extent the euro. Foreign exchange reserves assets can comprise banknotes, bank deposits, and government securities of the reserve currency, such as bonds and treasury bills. Some countries hold a part of their reserves in gold, and special drawing rights are also considered reserve assets. Often, for convenience, the cash or securities are retained by the central bank of the reserve or other currency and the "holdings" of the foreign country are tagged or otherwise identified as belonging to the other country without them actually leaving the vault of that central bank. From time to time they may be physically moved to the home or another country. Normally, interest is not paid on foreign cash reserves, nor on gold holdings, but the central bank usually earns interest on government securities. The central bank may, however, profit from a depreciation of the foreign currency or incur a loss on its appreciation. The central bank also incurs opportunity costs from holding the reserve assets (especially cash holdings) and from their storage, security costs, etc. Foreign exchange reserves are also known as reserve assets and include foreign banknotes, foreign bank deposits, foreign treasury bills, and short and long-term foreign government securities, as well as gold reserves, special drawing rights (SDRs), and International Monetary Fund (IMF) reserve positions. In a central bank's accounts, foreign exchange reserves are called reserve assets in the capital account of the balance of payments, and may be labeled as reserve assets under assets by functional category.

Currency crisis

A currency crisis is a type of financial crisis, and is often associated with a real economic crisis. A currency crisis raises the probability of a banking crisis or a default crisis. During a currency crisis the value of foreign denominated debt will rise drastically relative to the declining value of the home currency. Generally doubt exists as to whether a country's central bank has sufficient foreign exchange reserves to maintain the country's fixed exchange rate, if it has any.

Bank of France

Floating exchange rate

In macroeconomics and economic policy, a floating exchange rate (also known as a fluctuating 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 events. A currency that uses a floating exchange rate is known as a floating currency, in contrast to a fixed currency, the value of which is instead specified in terms of material goods, another currency, or a set of currencies (the idea of the last being to reduce currency fluctuations).
