Findings: The findings indicated that interest rate (β3=0.52939, P=003) have significant positive effect on share price volatility. The study recommended that the monetary committee at CBK should maintain stable interest rates in order to encourage borrowing as it would foster investment in the NSE and other sectors.

This approach allows businesses and investors to make more effective investment plans, as they can predict the cost of borrowing over time. Additionally, the monetary committee at the Central Bank of Kenya (CBK), responsible for setting the policy rate, should take into account how their decisions influence short-term interest rates in the economy. This consideration is important for the well-being of businesses, investors and the Nairobi Securities Exchange (NSE).
