Interest rates can affect currency rates significantly. Higher interest rates tend to attract more foreign investments, thereby increasing the demand for the domestic currency. This makes the domestic currency appreciate. Conversely, when the interest rates are lower, investors may seek better returns elsewhere, causing the domestic currency’s demand to fall and its value to depreciate.

Fundamentally, currency exchange rates represent the value of one currency in terms of another. These rates are determined by the demand and supply forces in the foreign exchange market. They are affected by many factors like economic indicators, political stability, trade balances and interest rates.

Currency exchange rates are crucial for various purposes like investments, international trade and even economic stability. They allow you to compare prices across countries, make global transactions possible and determine how economically competitive a nation is. Furthermore, exchange rates also impact inflation, tourism and FDI.

Market forces like demand and supply in the foreign exchange market primarily determine currency exchange rates. That said, central banks and governments also influence these rates indirectly through monetary policies and interest rate adjustments.
