Global currency markets experienced significant moves at the start of the week, driven by growing optimism that the United States and Iran are nearing a diplomatic agreement that could reopen the Strait of Hormuz and ease geopolitical tensions in the Middle East. US President Donald Trump stated over the weekend that an agreement with Iran is 'largely negotiated,' including provisions for reopening the Strait of Hormuz, though he later cautioned there is 'no rush for the deal' and that negotiations are ongoing [1][2][3][5]. US Secretary of State Marco Rubio described the current framework as solid and reiterated that diplomacy would be given every chance, but alternative measures remain on the table if a deal cannot be reached [2].
The anticipation of a US-Iran deal has led to a sharp decline in oil prices, with WTI crude falling nearly 6% to around $90, its lowest level in over two weeks [3]. This drop in oil prices has had a pronounced effect on currency markets, particularly benefiting oil-importing economies such as India and Japan. The Indian Rupee rallied, with USD/INR sliding to near 95.20, a two-week low, supported by both the oil price decline and comments from RBI Governor Sanjay Malhotra, who assured readiness to intervene in forex markets if necessary [3]. The Japanese Yen also gained ground, with USD/JPY trading around 158.90, as falling oil prices and a weaker US Dollar provided support. Market participants remain alert to potential intervention by Japanese authorities should the Yen approach the critical 160-per-dollar threshold [4].
The Euro, British Pound, and Canadian Dollar all strengthened against the US Dollar. The EUR/USD held gains around 1.1645, while GBP/USD approached the 1.3500 mark, a one-and-a-half-week high, as the weaker US Dollar and lower oil prices boosted risk sentiment [1][5]. The USD/CAD pair edged lower to around 1.3805, though the Canadian Dollar's gains were tempered by concerns over domestic economic growth [2]. Currency heat maps from multiple sources confirm broad-based US Dollar weakness, with the Greenback losing between 0.33% and 0.39% against the Euro and Pound, and up to 0.59% against the Australian Dollar [1][5].
Market implications were immediate: S&P 500 futures rose nearly 0.9% to around 7,540, reflecting strong risk appetite [1]. The US Dollar Index (DXY) hovered near 99.00, clinging to early losses [1]. The decline in oil prices and improved risk sentiment have also led to a recalibration of Federal Reserve expectations. According to the CME FedWatch tool, the probability of at least one Fed rate hike this year dropped to 57% from 67% on Friday [1], though other sources report a 41% probability of a 25-basis-point hike by year-end [4], and some traders are fully pricing in a hike in January 2027 due to persistent US inflation [5].
Despite the optimism, sources note that key issues remain unresolved between the US and Iran, including blockades on the Strait of Hormuz and Tehran's nuclear program [5]. President Trump emphasized that there is 'no rush' for a deal, which has tempered market enthusiasm and limited further US Dollar losses [1][3][5]. Foreign Institutional Investors continued to sell Indian equities, offloading Rs. 10,386.52 crore over the past four days amid concerns about corporate earnings and energy price shocks [3].
CONCLUSION
Currency and equity markets responded positively to hopes of a US-Iran deal, with risk assets rallying and the US Dollar weakening broadly. However, unresolved issues and cautious statements from US officials suggest that market optimism may be premature. The outlook remains sensitive to further developments in the negotiations and upcoming economic data releases.
