MONETARY POLICY PASS-THROUGH, EXCESS LIQUIDITY AND PRICE SPILLOVER: A COMPARATIVE STUDY OF CONVENTIONAL AND ISLAMIC BANKS OF PAKISTAN
This study investigates the comparative pass-through of policy rate to the retailprices, spillover of prices between Islamic and conventional banking systems, and theimpact of excess liquidity on these pass-throughs using data from interbank marketof Pakistan. The results suggest that the monetary policy shock affect retail prices ofIslamic banks similar to conventional banks, confirming the results of earlier studies.Moreover, there is a strong spillover between the prices of two systems; Islamicbanks are following (leading) the conventional banks in pricing the lending (deposit)products. Islamic bank has acquired advantage in the deposit pricing by taping thereligious depositors, which also may have promoted financial inclusion therebycontributing to the economic growth and improved income distribution in the society.Our findings suggest that the presence of excess liquidity have no effect on passthroughof policy rate in the Islamic system, which is contrary to the prevalent notion.However, excess liquidity significantly affects the spillovers of prices between thesystems. These results support the hypothesis that the Islamic banks are investing ininterest-based government securities indirectly via conventional banks. Our findingsmay help in enhancing the regulatory efficiency of the central banks and the conduct ofthe monetary policy in the countries where dual banking system exists.
