A weak currency is:
i. Good for exports from the country having weak currency
ii. May create difficult conditions for trade with the country having weak currency
iii. Good for import in the country having weak currency
Weak currency encourages exports as the exporter realises more value of the exports. Weak currency reduces terms of trade as the country has to give more of the exporting commodity to get a specific unit of the importing commodity. Weak currency reduces the price of domestic goods in the international market.
