Investigating the role of economic growth in the effect of oil revenue shock and exchange rate on the efficiency of Iran's banking network (Self-vector regression)

In the present study, the impact of positive and negative shocks of oil revenues, inflation and exchange rate in different economic growth states on the efficiency of the banking network using threshold structural vector autoregression model in the period of 1398:4-1387:1 It was discussed seasonally, according to the results, the effect of a positive shock to oil revenues in economic recession and boom is similar to the efficiency of the banking network, and it had a positive effect in the short term and a negative effect in the medium term. But the effect of positive shock to inflation and exchange rate on banking efficiency depends on different regimes of economic growth. The positive shock of inflation in the recession has had a negative effect in the short term and a positive effect in the medium term on the efficiency of the banking network. In the conditions of prosperity, inflation has had a positive effect on the efficiency of the banking network in the short and medium term. The positive shock of the exchange rate in recessionary conditions has only a short-term negative effect on the efficiency of the banking network, but in the conditions of prosperity, the positive shock of the exchange rate has a positive effect on the efficiency of the banking network in the short term and a negative effect on the efficiency of the banking network in the medium term.
