This research has focused on examining the connection between uncertainties in economic policies and exchange rates. This research extends the literature to this field by analyzing the impact of small to large negative along with small to large positive variations in the economic policy uncertainty on the currency rates. For this purpose, this research uses the Granger causality in the quantile test and a newly constructed multiple asymmetric threshold nonlinear ARDL (MATNARDL) model. When a nonlinear ARDL model is utilized, our results confirmed the nonlinear impact in three nations only. In contrast, when the MATNARDL technique is utilized, these findings do confirm the nonlinear effect for all nations. Furthermore, when the Granger causality in the quantile test is applied, the impact differs over various quantiles. In general, the enhanced framework encourages us to analyze better how EPU affects the exchange rate in the emerging seven (E7) nations. The findings of our research may be useful for state banks to design policies to make interventions in the foreign currency market.
