Currency is another name for money, usually applied in the context of international trade. It serves as a medium of exchange, a unit of account, and a store of value, facilitating economic transactions both domestically and internationally.
Historical Context
The concept of currency dates back to ancient civilizations, where items like shells, precious metals, and even livestock were used as mediums of exchange. The first standardized coins appeared in Lydia (modern-day Turkey) around 600 BCE. The paper currency, on the other hand, originated in China during the Tang Dynasty (618-907 CE).
Types of Currency
Hard Currency
Hard currency refers to currencies that are widely accepted around the world and are stable, usually backed by a strong economy. Examples include the US Dollar (USD), Euro (EUR), and Japanese Yen (JPY).
Soft Currency
Soft currency is less stable and not widely accepted outside its home country. Its value is more susceptible to fluctuations and may be prone to inflation. Examples include the Venezuelan Bolívar (VES) and Zimbabwean Dollar (ZWL).
Trading Currency
Trading currencies are widely used in global trade. The USD, for example, is the most common trading currency due to its global acceptance.
Over-Valued and Under-Valued Currency
- Over-Valued Currency: When a currency’s value is higher than its market equilibrium, it’s termed over-valued. This can harm exports as they become more expensive.
- Under-Valued Currency: Conversely, an under-valued currency is worth less than its market equilibrium, potentially boosting exports by making them cheaper on the international market.
Key Events

This agreement established a system of fixed exchange rates with the USD pegged to gold. It led to the creation of the International Monetary Fund (IMF) and the World Bank.
Nixon Shock (1971)
US President Richard Nixon ended the gold standard, leading to the floating exchange rate system we have today.
