Võtmevaluuta

Võtmevaluuta, also known as key currency, is a foreign currency that is held in significant quantities as part of a country's foreign exchange reserves. These currencies are widely used in international trade and finance and are considered stable and reliable. The most common examples of võtmevaluuta include the US dollar, the Euro, the Japanese Yen, and the British Pound Sterling.

The primary function of a võtmevaluuta is to facilitate international transactions. Countries use them to settle trade debts, invest in foreign assets, and manage their own currency's exchange rate. The dominance of a particular currency as a võtmevaluuta often reflects the economic strength and global influence of its issuing country. For instance, the US dollar's status as the world's primary reserve currency is largely due to the size and stability of the US economy.

Holding võtmevaluuta provides several benefits to a country. It allows for easier access to international capital markets and can act as a buffer against economic shocks. Central banks often intervene in foreign exchange markets using their holdings of võtmevaluuta to influence their own currency's value. However, over-reliance on a single võtmevaluuta can also expose a country to risks associated with the economic policies and stability of the issuing nation. The composition of a country's foreign exchange reserves, including its holdings of võtmevaluuta, is a key indicator of its financial standing and economic strategy.
