1.Interest rates
The interest rate level is moved higher or lower by a country's central bank to either stimulate or slow down an economy. Higher interest rates impose a more costly fee to borrow money while lower interest rates lessen the fee and usually spur more borrowing
2.Economic growth
The strength of an economy can go a long way to boosting the strength of the nation's currency. A strong growth rate in a country will see a growing demand for products and services with better job prospects for workers as well as being an attractive destination for capital and investments.
3.Inflation
When a product rises in price, it signals that there is an underlying demand for that product. Higher prices may not seem good to a consumer, but it is generally considered healthy for a country to have a moderate increase in inflation in a growing economy.
