Exchange rate is considered to be influenced by the crude oil price, foreign exchange reserves and trade balances especially for oil importing countries. This monograph addresses this aspect in the context of South Korea and Bangladesh. The findings suggest that there is no short-run relationship between oil price and exchange rates in both Bangladesh and South Korea, however, oil prices influence exchange rate in the long-run only in Bangladesh. Evidence of the effects of foreign exchange reserve and trade balances is also mixed for these two countries.
