Most of businesses financing in the country done by the banking network and banking network play a very important role in achieving macroeconomic goals. Accordingly, in the present study, the effect of fluctuations of asset markets (exchange rate, oil price and stock market index) on financial instability index over a period of 2009-2018 monthly is investigated by using the Markov Switching model. The wavelet transform model is used to extract exchange rate fluctuations, oil prices and stock market index. The results show that the effect of exchange rate fluctuations in different regimes and different time periods is different, so that in the short run the exchange rate fluctuations in the high regime of the financial instability index have a different effect than the other periods. Oil price fluctuations have a positive and significant effect in the medium- and long-term periods and in all regimes, and this effect will be stronger in the long run. Also, fluctuations in the stock market have a negative and significant effect only in the short run and under conditions of low regime of financial instability index. These results show that fluctuations have different effects with respect to time period as well as level of financial instability. Therefore, the management of foreign exchange rate and stock markets should take into the account of financial instability level and the timeframe for fluctuations.

The main goal of this study is survey and testing effects of asymmetric exchange rate fluctuations (in terms of positive and negative momentum) on private sector investment in Iran. At first, for exchange rate shocks, we used Hodrick-Prescott filter and positive and negative predicted and non-predicted shocks have been obtained. In addition, in specification of private sector investment equation, the effect of other variables such as gross domestic product (without oil) and public investment has been considered. For this purpose, using Auto Regressive Distributed Lag method (ARDL) and Error Correction Model (ECM), long run and short run relationship between private sector investment and factors affecting it during the years 1978 to 2010 have been evaluated. the results show that there is an asymmetric effects of exchange rate fluctuations on private sector investment but exchange rate positive shocks are more effective than negative shocks.
