The purpose of this paper is investigation of monetary policy shock effects on stock market price index in Iran. We used legal deposit ratio, banks debt to central bank and private sector debt to banks as measurements of monetary policy. Also, Tehran stock Exchange Price Index (TEPIX) was used as an index of stock market changes. Portfolio theory and asset price channel are our theoretical view of subject. Also we added house price index and exchange rate to our variables because of their role and importance in people portfolio. Quarterly data from 1370q1 to 1389q3 used for this study Cointegration and Vector Error Correction Model were applied for statistical inference. For investigating shocks effect we used Impulse Response Function (IRF) and Variance Decomposition (VD). Our results showed that monetary policy has positive but narrow effect in stock market changes. Among monetary variables, bank debt to central bank is more powerful than other variables affecting stock price index.

The aim of this paper is to consider the effects of monetary policy on production and prices through asset price channel (the housing price index) in Iran during 1368Q1 to 1387Q4. By Vector Error Correction (VEC) Model, the effect of monetary policy has been considered through this channel. In general, the results show that the debt of banks to the central bank as instruments of monetary policy through the housing price index, at least in the short run could increase the production level and decreases prices. Thus central bank with given facilities to banks can directly and through the housing price index strengthen production level and control prices in the short run. Also we found that shock of the required reserve ratio in general, directly affects production levels and don’t have any effect on production level and prices through the housing price index. Therefore, in using of these tool as instruments of monetary policy, the housing price index channel in monetary transmission policy, has a little effect and only on the production.
