US-Iran Strikes Spark Oil Surge and Dollar Weakness Amid Market Jitters

US President Donald Trump announced that any strikes on Iran would be limited, emphasizing that the Strait of Hormuz remains 'in extremely good shape' with 'a lot of oil coming out of Hormuz.' Trump noted that ships passed through the Strait with Navy assistance, averaging 30 ships a night, underscoring the continued flow of oil despite heightened tensions in the region [1].

The escalation of the US-Iran conflict led to a jump in energy prices, with West Texas Intermediate (WTI), the US oil benchmark, surpassing the $85.00 threshold following strikes by both the US and Iran [2]. This surge in oil prices contributed to a deterioration in risk appetite, as investors grew more cautious amid geopolitical uncertainty [2].

Despite the risk-off sentiment and higher energy prices, the US Dollar weakened, with the US Dollar Index (DXY) falling by 0.25% [2]. The Mexican Peso appreciated by about 0.20% against the US Dollar, with USD/MXN trading at 16.99 after reaching a daily high of 17.04 [2]. The FX market reaction was notable, as traders punished the Greenback even as broader sentiment soured [2].

Market participants are also focused on upcoming US economic data releases, including ISM Manufacturing and Services PMIs and Nonfarm Payrolls for August, which could provide further insight into the strength of the US labor market [2]. In Mexico, ongoing USMCA free trade agreement talks and the release of August Consumer Confidence data on September 3 are key events for the Peso [2].

Technical analysis indicates that USD/MXN remains in a bearish trend, trading below key moving averages and trend lines, with the Relative Strength Index at 38.8 suggesting persistent selling pressure [2].

CONCLUSION

The US-Iran conflict has triggered a surge in oil prices and a risk-off mood, yet the US Dollar weakened as traders shifted away from the Greenback. The Mexican Peso benefited from this dynamic, appreciating against the Dollar. Market attention now turns to upcoming economic data and ongoing trade negotiations, which could further influence currency movements.
