Abstract The Strait of Hormuz, as one of the world’s most strategic energy chokepoints, plays a vital role in the maritime trade of crude oil and natural gas, and many Asian economies are heavily dependent on it. Following the onset of the 2026 tensions and conflicts, vessel traffic in the strait has sharply declined, with more than 95% of shipping flows disrupted. Daily vessel crossings have dropped from several per day to nearly zero, with only a few limited transits permitted under special authorization. The absence of effective alternative routes—especially for countries reliant on energy exports through this passage—has placed significant pressure on global markets and heightened concerns about the stability of supply. Under such circumstances, Asian markets, the primary destination for oil and gas passing through Hormuz, face the greatest vulnerability. If this situation persists, rising transportation costs and escalating geopolitical risks could seriously challenge the stability of the global energy market. The geopolitical importance of the strait means that any disruption extends far beyond the region, producing immediate consequences for energy and financial markets as well as national economies. For energy exporters, this results in reduced foreign‑exchange revenues, while energy importers face higher costs, inflationary pressures, and slower economic growth.

Abstract This article examines the relationship between crude oil trade, economic growth, and the real exchange rate in Iran from 1979 to 2023, utilizing the Autoregressive Distributed Lag (ARDL) approach. The findings indicate that crude oil exports have a negative and statistically significant influence on the real exchange rate. Conversely, crude oil imports have a positive and significant effect on the real exchange rate. Additionally, the budget deficit from the previous period has positively impacted the real exchange rate. Gross Domestic Product (GDP) has also demonstrated a significant positive effect on the real exchange rate. In contrast, the monetary base has shown a significant negative effect on the real exchange rate. Long-term analyses reveal that oil export variables negatively affect the real exchange rate, while crude oil imports contribute positively. Over the long term, GDP maintains a significant positive effect on the real exchange rate, whereas the budget deficit and monetary base variables do not significantly influence the real exchange rate. Short-term dynamics suggest that the real exchange rate from the previous period positively and significantly affects the current real exchange rate. Moreover, the budget deficit variable in the current period negatively and significantly impacts the real exchange rate. The monetary base also has a significant negative effect on the real exchange rate; Central Bank assets have been utilized as a proxy for the monetary base.
