Why is a system for exchanging currencies necessary for international trade?

To control the global money supply
To increase trade barriers
To manage price stability and currency risk
To create a universal method for accurate currency exchange

A system for exchanging currencies is necessary for international trade for several reasons:

1. To facilitate transactions: Different countries have their own currencies, and without a currency exchange system, it would be difficult for businesses and individuals to engage in trade across borders. The system allows for the conversion of one currency into another, enabling smooth transactions between buyers and sellers.

2. To manage price stability and currency risk: Currency exchange rates can fluctuate due to various factors such as economic conditions, trade policies, and investor sentiments. A currency exchange system helps in managing these fluctuations and minimizing the risk associated with currency exchange. It provides a mechanism for setting exchange rates and reducing volatility, thereby promoting price stability and predictability in international trade.

3. To ensure accuracy and fairness in currency exchange: A universal method for accurate currency exchange is necessary to ensure fairness and transparency in international trade. It allows businesses and individuals to accurately determine the value of one currency in relation to another and facilitates fair and efficient pricing of goods and services in international markets.

4. To promote trade and economic growth: A currency exchange system plays a crucial role in promoting trade by reducing barriers and facilitating economic transactions. It allows businesses to access foreign markets, import goods, and export products more easily. This system encourages international trade relationships and enables countries to benefit from comparative advantages, leading to economic growth and development.

It is important to note that although a currency exchange system assists in international trade, it does not control the global money supply or increase trade barriers. Rather, it helps in managing currency fluctuations, promoting price stability, and facilitating trade.
