What Does Excess Bank Liquidity Say About the Loan Market in Less Developed Countries?

Evidence about developing countries’ commercial banks’ liquidity preference suggests the following about their loan markets: (i) the loan interest rate is a minimum mark-up rate; (ii) the loan market is characterized by oligopoly power; and (iii) indirect monetary policy, a cornerstone of financial liberalization, can only be effective at very high interest rates that are likely to be deflationary. The minimum rate is a mark-up over a foreign interest rate, marginal transaction costs and a risk premium. A calibration exercise demonstrates that the hypothesis of a minimum mark-up loan rate is consistent with the observed stylized facts.
