This study examines the relationship between stock price and the interest rate during the period from July
2012 to December 2015. Average daily stock prices calculated by Colombo Stock Exchange (CSE) and
Sri Lanka Interbank Offer Rates (SLIBOR) are used as dependant variable and independent variable
respectively. Accordingly, all Share Price Index (ASPI) and the Standard of CSE is used to analyse the
overall impact of interest rate on stock prices whereas Standard and Poor Price Index (S & P) of CSE is
used to measure the relation between stock prices of selected companies (Blue Chips) and interest rate.
Regression is mainly used to examine the relation between stock prices and interest rates. As theory
suggest, the study finds that both share prices reflected by ASPI and S&P negatively correlate with the
interest rate. The findings urge policy makers and other interested parties to assess the impact of interest
rate as a significant macroeconomic variable.
