It’s the cause of changes and fluctuations in consumer and wholesale price indices that are calculated as the basis of inflation. The present study investigates the instability of the exchange rate on the private sector's consumption using annual data for the period 1352-1390. In this regard, values of the real exchange rate volatility using the pattern of generalized autoregressive conditional heteroskedasticity (GARCH), and then the impact of the real exchange rate instability on private sector consumption is surveyed by using the method of Autoregressive-Distributed Lag (ARDL). The results of estimations show that in long term, Disposable income, liquidity, real exchange rate and the volatility of the real exchange rate have positive effect and Real interest rates have a negative impact on private sector consumption.
