An examination of Iran's economic developments over the past five decades has shown that Iran's economy has always had a high inflation rate. Therefore, it is important to pay attention to the factors affecting inflation in the country. The purpose of this study is to investigate the relationship between macroeconomic variables including liquidity, monetary base, oil revenues, budget deficit, economic growth and inflation in Iran in the period 1370-1399. For this purpose, two approaches of combining the discrete wavelet maximum overlap approach - Granger causality and the wavelet coherence based on the continuous wavelet approach have been used. The advantage of using the wavelet approach is that it allows the analysis of variables in two dimensions of time and frequency. The results of the analysis of both approaches showed that in the short run, the growth of liquidity and oil revenues will increase inflation. The results of long-term research show that the rate of inflation increases the growth of liquidity. Also, in the long run, the budget deficit is the cause of inflation, and in the short run, the inflation rate has been a factor influencing the growth rate of the budget deficit. A study of the analysis of phase differences in the time series of economic growth and inflation showed that in the long run, economic growth without oil and inflation are non-phase.In other words, the concept of non-phase in relation to these two variables means that economic growth without oil and inflation did not move in the same direction.
