Do interest rate controls work? Evidence from Kenya

摘要

This paper reviews the impact of interest rate controls in Kenya, introduced in September 2016. The intent of the controls was to reduce the cost of borrowing, expand access to credit, and increase the return on savings. However, we find that the law on interest rate controls has had the opposite effect of what was intended. Specifically, it has led to a collapse of credit to micro-, small-, and medium-sized enterprises; shrinking of the loan book of the small banks; and reduced financial intermediation. Because of their adverse effects on bank lending, we estimate that the interest rate controls have reduced economic growth by 1/4-3/4 percentage points on an annual basis. We also show that interest rate caps reduced the signaling effects of monetary policy. These suggest that (1) the adverse effects could largely be avoided if the ceiling was high enough to facilitate lending to higher-risk borrowers and (2) alternative policies could be preferable to address concerns about the high cost of credit.
