Market Power and Interest Rate Spreads in the Caribbean

This paper investigates the determinants of the high bank spreads observed in the Caribbean over the financially liberalised period of the 1990s. A theoretical model is formulated and tested using panel data. Among other factors, market power is found to be one of the main influences on these large spreads. A major conclusion of the paper is that to reduce interest rate spreads, alternatives to commercial banks' loans should be encouraged, and the recent move to impose monetary regulations on non-banks be discouraged.
