The currency exchange rates are determined by the market. The currency is free-floating and as a result its rate is not fixed as was done before. The rates in the market are determined by the extent of demand and supply of the currency in the market. As a result, its rates constantly changed and fluctuated. Earlier the currency rate was based on the fixed exchange rate when a currency was fixed with reference to another by the government who could change or devalue this rate as and when needed. Between World War II and 1966 the Western European countries fixed the exchange rates to the dollar. The market based exchange was adopted later.

Whenever there is a change in the value of one currency, the exchange rate with another currency will change. When the demand for a currency increases and is more than the supply, it becomes more valuable. But when the demand is lower than the supply, the value of the currency declines. The increase in demand for a currency can be due to many reasons. There could be an increase in the transaction demand for the currency. Or there could be an increase in the speculative demand for the currency. The transaction demand is related to the level of business activity of the country, the employment levels and the gross domestic product (GDP). When more people are employed, the more will be the spending on goods and services.

The change in the demand for currency as a result of business activity is adjusted by the central banks by adjusting the available money supply. It is difficult for the central banks to adjust to the demand for money from speculation. They try to do this by adjusting the interest rates. With higher interest rates, there is an increase in the purchase of that currency. The demand for the currency increases. Currency speculation is considered to undermine the economy of a country as large currency speculators can unduly influence the exchange rates.

Investment is central to business management as well as finance and economics. Instead of consuming the resources, when these resources are allocated for the creation of future benefits, then such allocation is called investment. Earning of profit and future income is the basic motive for investment. Assets that fulfill these are the objects of such investments by individuals or organizations. Moreover it is the assets that have a lower risk with a potential of profit or income that are where investments are most likely to be made. But if the asset or instrument is not properly analyzed for its risk and potential benefits with the real possibility of even the loss of the principal invested, and yet investment is made, then this is speculation and not investment.

Investments differ in economics and finance. In economics, investment mean investing on productive real assets such as tangible goods as a factory, machines or a house or intangibles as education or training. In finance, investment refers to financial assets as investment in bank deposits, money markets or capital markets or even in liquid assets as precious metals, real estate, shares, equity, bonds, foreign currencies, or collectibles.

Investments can be made indirectly through intermediaries. These intermediaries include banks, mutual funds, pension funds, insurance companies, collective investment schemes, and investment clubs. These intermediaries then make investment decisions either on real assets or financial assets to earn an income or profit which then are shared with the original investors. Alternatively, investors can invest directly in shares or buy assets. Investment comes with a risk of capital loss.

Foreign exchange market is where currency is traded. When trade in goods and services were limited as in olden days, the system of transaction was through barter. Barter was a system where the transaction was carried out by exchange of goods. But with the expansion of trade, this form of transaction became quite cumbersome. An intermediate between the goods traded was invented. Formerly this was in the form of coins made of metals which had intrinsic value such as gold, silver and copper. The use of coins to buy and sell goods became convenient. The problem was when the value of goods sold or bought were high. It required that much more coins which was just too cumbersome posing a practical problem. Moreover trade further expanded. Something easier to handle had to be invented. That was how banknotes made its appearance to substitute coins. Initially the banknotes were pegged to valuable metals such as the gold standard. But this was later de-linked. Now the value of banknotes comes from the value decreed by governments. These banknotes are issued by banks that are controlled by national governments.

Each country had its own currency. Trade between countries required that the transactions had to be carried out in multiple currencies. The expansion of international trade in goods and services required that the central banks and governments purchase more of the currencies of countries with which they carried out trade. Currency trading emerged and soon became a distinct economic activity. The exchange rate becoming determined by the market, the demand and supply regime, more and more players entered the market such as currency traders, financial institutions, and money managers.
