A weaker currency makes international purchases more expensive as you need to pay more rupees for the same product than you did previously. For example, if you were getting a foreign product for $1 in January, then you had to pay 74 rupees back then. But with the Indian currency weakening to 80 per dollar, you would not need to pay 80 rupees for the same product. The current trend suggests prices of foreign goods could rise further on expectations of more rupee weakening ahead.
India imports over 80 per cent of its oil needs, and a weakening currency adds to the cost of international oil and energy products. That will result in higher fuel and energy prices for consumers in India as oil refineries and marketing companies pass on the additional exchange rate burden.
A weakening currency will mean that you would now have to pay more for the same foreign education and international travel than you did before. For example, if the cost of travelling to an international country in January was $1,000, that translated into ₹ 74,000 back then, but now you would have to pay ₹ 80,000 for the same trip.
The rupee has weakened by over 7 per cent this year against the dollar, suggesting US education and travel has become 7 per cent more expensive in just the last six months.
A weakening currency helps exports and makes Indian goods competitive in international markets. Exporters who were getting ₹ 74 in exchange for a product worth $1 would now get ₹ 80 for the same.
