What Are Foreign Exchange Reserves?
Foreign exchange reserves are assets held on reserve by a central bank in foreign currencies. These reserves are used to back liabilities and influence monetary policy. It includes any foreign money held by a central bank, such as the U.S. Federal Reserve Bank.
- Foreign exchange reserves are assets denominated in a foreign currency that are held by a nation’s central bank.
- These may include foreign currencies, bonds, treasury bills, and other government securities.
- Most foreign exchange reserves are held in U.S. dollars, with China being the largest foreign currency reserve holder in the world.
- Economists suggest that it’s best to hold foreign exchange reserves in a currency that is not directly connected to the country’s own currency.
How Foreign Exchange Reserves Work
Foreign exchange reserves can include banknotesdeposits, bonds, treasury bills and other government securities. These assets serve many purposes but are most significantly held to ensure that a central government agency has backup funds if their national currency rapidly devalues or becomes entirely insolvent.
It is a common practice in countries around the world for a central bank to hold a significant amount of reserves in its foreign exchange. Most of these reserves are held in the U.S. dollar since it is the most traded currency in the world. It is not uncommon for the foreign exchange reserves to be made up of the British pound (GBP), the euro (EUR), the Chinese yuan (CNY) or the Japanese yen (JPY) as well.
Economists theorize that it is better to hold the foreign exchange reserves in a currency that is not directly connected to the country’s own currency in order to provide a barrier should there be a market shock. However, this practice has become more difficult as currencies have become increasingly intertwined as global trading has become easier.
Foreign exchange reserves are not only used to back liabilities but also influence monetary policy.
Example of Foreign Exchange Reserves
The world’s largest current foreign exchange reserve holder is China, a country holding more than $3 trillion of its assets in a foreign currency. Most of their reserves are held in the U.S. dollar. One of the reasons for this is that it makes international trade easier to execute since most of the trading takes place using the U.S. dollar.
Saudi Arabia also holds considerable foreign exchange reserves, as the country relies mainly on the export of its vast oil reserves. If oil prices begin to rapidly drop, the country’s economy could suffer. It keeps large amounts of foreign funds in reserves to act as a cushion should this happen, even if it’s only a temporary fix.
U.S. foreign exchange reserves totaled $247 billion, as of March 25, 2022, compared to China’s over $3 trillion.
Russia’s foreign exchange reserves are held mostly in U.S. dollars, much like the rest of the world, but the country also keeps some of its reserves in gold. Since gold is a commodity with an underlying value, the risk in relying on gold in the event of a Russian economic decline is that the value of gold will not be significant enough to support the country’s needs. As of February 2022, Russia’s foreign exchange reserves totaled some $630 billion. However, sanctions imposed by the European Union (EU), the U.S., and other nations in response to Russia’s invasion of Ukraine in February 2022 rendered most of those reserves inaccessible to the central bank.
Another danger of using gold as a reserve is that the asset is only worth what someone else is willing to pay for it. During an economic crash, that would put the power of determining the value of the gold reserve, and therefore Russia’s financial fallback, into the hands of the entity willing to purchase it.
