For a percentage point change in interest rate spread, savings increases by 6.6 percent, investment increases by 8.4 percent and consumption by 1.1 percent. The study concluded that there is a significant relationship between interest rate spread on savings, investment and private consumption in Nigeria. Base on the findings, the study recommended that the Central Bank of Nigeria should put in place measures to monitoring interest rate spread related measures such as lending rate, deposit rate, operation efficiency, liquidity risk, provision and gross domestic rate to boost financial system in Nigeria.
