High inflation erodes purchasing power and can lead to currency depreciation. High fiscal deficit can pressure the government's finances and potentially lead to inflationary financing or increased borrowing, impacting currency stability. High crude oil prices negatively affect the currency of net oil- importing countries like India by increasing the import bill and demand for foreign currency. All these factors are interconnected and directly or indirectly influence the supply and demand dynamics in the foreign exchange market, thereby affecting the exchange rate.
