Exchange rate uncertainty, along with the intensification of cost and psychological pressures, is considered one of the most important drivers of inflationary expectations instability in the Iranian economy. On the other hand, controlling inflationary expectations is very crucial for establishing stability in the country's economy. Given the importance of this issue, the aim of the present study is to investigate the effect of exchange rate uncertainty on inflationary expectations in the complex conditions of the Iranian economy, using seasonal data from 2016 to 2025. Since numerous economic, political, social, and cultural factors can be effective in the formation of inflationary expectations, the fuzzy regression method has been used in the present study to estimate the model. Because this method has a high ability to examine correlation in conditions of uncertainty and uncertainty. The findings of this study showed that exchange rate uncertainty has a positive and strong effect on inflation expectations, such that the role of this factor in the formation of inflation expectations in the Iranian economy is 26 percent.
