Abstract:
Interest rates and exchange rates are considered to be one of the most discussed areas
under International Finance. When considering the main theories that explore on these
two variables, Uncovered Interest Rate Parity (UIP) states that the interest rate
differential is an unbiased predictor of the spot exchange rate changes. The impact on
investors’ attitude is that they would be indifferent towards the returns on domestic
and foreign assets denominated in same currency thereby eliminating any short term
arbitrage profits. Studies based on the relationship between these two variables are
rare for developing countries like Sri Lanka. Therefore in order to bridge that gap
identified through search for literature, this study is focused on testing UIP for Sri
Lanka. Monthly data on LKR/GBP exchange rate for the period from 2001-2014 and
three month interest rate for the two countries , were used for this purpose.
Autoregressive Distributed Lags method was employed to test the UIP. The findings
reveal that there is no evidence to prove the existence of the UIP for the selected
currency compared against the Sri Lankan Rupee.
