As a medium in the transmission mechanism of monetary policy makes the banking industry needs to be heavily regulated. Indonesian Bank policies to strengthen the capital structure through a merger or consolidation will reduce the number of existing bank and affect the market structure of the banking industry as a whole, then affect the level of competition. The ability of monetary policy to influence interest rates will determine the effectiveness of monetary policy transmission. Using Vector Error Correction Model (VECM), this study aimed to identify whether the market structure of the banking industry affect the effectiveness of monetary policy transmission through the interest rate channel. The data used is monthly time series of BI Rate, deposits rate, lending rates , and concentration ratio of the four largest bank (CR4) start from January 2008 until October 2012. CR4 has positive impact on bank lending rates, so that the higher degree of concentration in the banking industry will reduce the effectiveness of monetary policy.
