Explain how exchange rates are formed in the market.it is to do with economics
Exchange rates are formed by supply and demand, just like the prices of most other commodities. The more demand there is for a given currency, the higher its exchange rate will be.
Typically, demand for a currency will occur for one of two reasons. First, people from other countries may want to buy goods from a given country. They have to buy that country's money in order to buy its goods.
Second, people fror foreign countries may want to invest in another country -- buy its stocks and bonds, for example. In this case too, they must buy that country's currency so they can use it to invest in the things they want.
