The reopening of the Strait of Hormuz by Iran has significantly impacted global markets, leading to a sharp decline in oil prices and a weakening of the US Dollar. Iranian Foreign Minister Abbas Araghchi announced that, in line with the ceasefire in Lebanon, passage for all commercial vessels through the Strait is now open for the remaining period of the truce, with transit coordinated by Iran’s Ports and Maritime Organisation [2]. This development has alleviated immediate fears of prolonged oil supply disruptions, causing West Texas Intermediate (WTI) crude prices to plunge more than 10%, with prices dropping to near $83.00 per barrel [1][2].
The US Dollar Index (DXY) has lost momentum near 98.00 as safe-haven demand fades on the reopening news, though downside remains limited due to lingering geopolitical risks [1]. The USD was the strongest against the Euro, but overall, it weakened against most major currencies, with USD/JPY falling to around 158.18, down 0.61% on the day [1][2][3]. The Japanese Yen strengthened, benefiting from both a softer USD and easing oil prices, which is particularly supportive for Japan given its reliance on imported energy [2].
Market sentiment has improved on hopes of a potential US-Iran peace deal, but uncertainty persists due to unresolved issues, especially regarding nuclear negotiations [2]. The sharp drop in oil prices is easing immediate inflation risks and reviving expectations for Federal Reserve (Fed) rate cuts, while also reinforcing the Bank of Japan’s gradual policy normalization path [2]. Technical analysis indicates that USD/JPY holds a bearish near-term bias, with downside momentum outweighing buying interest as the pair trades below key moving averages and technical indicators remain negative [2].
Federal Reserve Governor Christopher Waller commented that the ongoing Middle East conflict increases inflation and job risks, and that the job market break-even rate is likely around zero [3]. Waller emphasized the difficulty in analyzing the job market amid recent shocks and stated that periods of negative job growth might not indicate a recession [3]. He also warned that a prolonged conflict could lead to a lasting inflation impact, while a quick resolution would allow markets to look through the energy price shock [3]. Waller projected that March headline PCE inflation is likely to hit 3.5% year-over-year [3].
According to [1], while the Strait of Hormuz is currently open, Iran has warned it may consider closing it again if the United States maintains its naval blockade, which would be seen as a violation of the ceasefire. This ongoing uncertainty keeps markets fluctuating between relief and renewed caution.
CONCLUSION
The reopening of the Strait of Hormuz has triggered a sharp drop in oil prices and a weakening of the US Dollar, with markets reacting positively to the reduced risk of supply disruptions. However, persistent geopolitical risks and unresolved US-Iran issues continue to weigh on sentiment. Forward-looking statements from the Federal Reserve highlight ongoing concerns about inflation and job market stress, suggesting that volatility may persist.
