Exports and imports of goods and services have grown rapidly since the World War II. Foreign trade is more important for all the countries to increase the foreign exchange holdings of all the economies in the current days. An increasing volume of trade for a country benefits the standard of living of our population as well as economic development in several ways. In spite of the steady growth in international trade, there are some frequent concerns about the impact of exchange rate, inflation rate and MIBOR movements on foreign trade on export and import activities of a country. This paper empirically investigates the impact of exchange rate, inflation and MIBOR volatility on the exports and Imports in terms of current account, capital account and overall account position in India.
Keywords: Foreign Trade, Export, Import, Exchange Rate, Inflation Rate, MIBOR
Import and Export have been growing importance of vibrant and emerging economies in the global trade and the share of total output in the globe. In the early 1970s, the collapse of the Bretton Woods System triggered on whether the exchange rate variability is a curb of global trade. Recently, 1997 Asian financial crisis and 2008 global financial crisis were rekindled on exchange rate, inflation and MIBOR effects on trade; thereby the overall trade activity is an aggregation of decisions of individual firms of any nation. India has launched its policy reform agenda and implemented a host of liberalization reforms, primarily targeting the foreign exchange market and the tradable sectors. India shifted to a more market oriented exchange rate system through devaluations and deregulations in 1992-93. Since then the exchange rate has mostly been under a managed floating regime with the Reserve Bank of India intervening from time to time to stabilize the nominal exchange rate.
An exchange rate is the price of one currency in terms of another. Exchange rate, like price of any other commodity, is determined in a market called Foreign Exchange market. Foreign exchange market is an international financial market meant for exchange of various national currencies. It is said that the Sun never sets on the foreign currency market like on the erstwhile British Empire. Real exchange rate is commonly known as a measure of international competitiveness. It is also known as index of competitiveness of currency of any country and an inverse relationship between this index and competitiveness exists. Lower the value of this index in any country, higher the competitiveness of currency of that country will be.
Inflation not only creates problems within the economy, but also in the sphere of external trade of a country, that is, countries trade balances with the rest of the World. Country’s trade relations with the other countries involve exports and imports of goods and services and how much a country will export and import depends, amongst other thing, on the domestic price level and variation in it, that is, the rate of inflation.
The interest rate at which banks can borrow funds, in marketable size, from other banks in the Indian interbank market is called MIBOR. The Mumbai Interbank Offered Rate (MIBOR) is calculated everyday by the National Stock Exchange of India (NSEIL) as a weighted average of lending rates of a group of banks, on funds lent to first-class borrowers. The MIBOR was launched on June 15, 1998 by the Committee for the Development of the Debt Market, as an overnight rate. Since the launch, MIBOR rates have been used as benchmark rates for the majority of money market deals made in India.
The study with the objective of the exchange rate, inflation rate and MIBOR effects on foreign trade with respect to import and export of current account, capital account and overall positions of the trade. Using annual time series data, the Multiple Regression analysis has been carried out for the period 2005-06 to 2013-14. The study has taken independent variables i.e., exchange rate, inflation rate and MIBOR and dependent variables i.e., exports and imports. Hence in order to understand the effects of exchange rate, inflation rate and MIBOR changes on trade balance, it is important to analyze how exchange rate, inflation rate and MIBOR fluctuations affect the global trade.
The multiple correlation co-efficient indicates that the correlation among the independent and dependent variables is positive and the statistic, which ranges from -1 to +1, does not indicate statistical significance of this correlation. The analysis of variance information provides the breakdown of the total variation of the dependent variable in to the explained and unexplained portions. The SS Regression is the variation explained by the regression line; SS Residual is the variation of the dependent variable that is not explained. The F-statistic is calculated using the ratio of the mean square regression (MS Regression) to the mean square residual (MS Residual). The results of the estimated regression line include the estimated coefficients, the standard error of the coefficients, the calculated t-statistic, the corresponding p-value, and the bounds of both the 95% confidence intervals.

The coefficient of determination, R2, is 81.06% and it means that close to 81% of the variation in the dependent variable (Export) is explained by the independent variables (Exchange Rate, Inflation Rate and Mumbai Interbank offered Rate). The adjusted R-square, a measure of explanatory power, is 0.6971. The standard error of the regression is 1201880.632, which is an estimate of the variation of the observed Export in billions, about the regression line.

The exchange rate and MIBOR have significant negative impact on exports and imports, but inflation rate has significant positive impact on exports and imports of current account, capital account and overall account in India. It reveals that these factors are playing crucial role on import and export of our economy. The government and the authority should concentrate on the control over volatility in exchange rate, inflation rate, MIBOR will give positive impact on foreign trade in India. Hence, the stability in exchange rate, inflation rate, MIBOR will increase the export and decrease the import activities in India.
