The US Dollar Index (DXY) remained in positive territory, hovering around 99.00 after paring earlier gains during Asian trading hours on Monday, as safe-haven demand for the Greenback increased following the failure of US-Iran peace talks in Islamabad. US Vice President JD Vance confirmed that the negotiations ended without a deal after 21 hours, and US President Donald Trump announced that Washington would begin blockading all ships entering or leaving the Strait of Hormuz. The US Central Command (CENTCOM) stated that operations targeting maritime traffic to and from Iranian ports would commence at 10 AM ET (14:00 GMT) Monday [1][3][4].
The collapse of the talks and the subsequent US blockade announcement heightened geopolitical tensions, leading to a sharp rally in crude oil prices. West Texas Intermediate (WTI) opened the week with a bullish gap, trading about 7.5% higher near $97.10 per barrel. This surge in energy prices revived inflationary concerns and reinforced expectations that the Federal Reserve (Fed) may delay rate cuts or even tighten policy further [2][3][4]. The US Bureau of Labor Statistics reported that annual CPI rose to 3.3% in March from 2.4% in February, with a monthly increase of 0.9% after 0.3% previously. Core CPI rose 0.2% month-over-month and 2.6% year-over-year, matching expectations [1][4]. San Francisco Fed President Mary Daly stated that if inflation remains elevated, the Fed will hold rates steady until price stability is achieved, but a rate cut is possible if the Iran conflict eases quickly and oil prices decline [1].
The risk-off sentiment pressured risk-sensitive currencies. The AUD/USD pair opened with a bearish gap, trading around 0.7030 and down 0.50% for the day, while the NZD/USD pair traded around 0.5800, both weighed down by the stronger US Dollar and global risk aversion. Technical analysis indicated that AUD/USD buyers were defending the 0.7000 area, while NZD/USD remained under pressure despite a slight recovery from daily lows [2][3]. According to a table of percentage changes, the US Dollar was the strongest against the Australian Dollar, gaining 0.51% [3].
The surge in the US Dollar and higher yields also impacted commodities. Silver (XAG/USD) halted its five-day winning streak, falling over 2.5% and trading around $73.80 per troy ounce. The non-interest-bearing metal lost appeal as the effective shutdown of the Strait of Hormuz drove energy prices higher, heightening inflation and reinforcing expectations for a higher-for-longer Fed stance [4].
Despite the escalation, reports indicated that regional countries are working to bring the US and Iran back to the negotiating table within days, keeping the door open for further diplomacy and capping the US Dollar's gains [2][3].
CONCLUSION
The failure of US-Iran peace talks and the subsequent US blockade of the Strait of Hormuz triggered a surge in the US Dollar and crude oil prices, dampening risk sentiment and weighing on risk-sensitive assets. Stronger US inflation data and rising energy prices reinforced expectations for a hawkish Fed, reducing the likelihood of near-term rate cuts. While diplomatic efforts may resume, markets remain focused on geopolitical risks and inflationary pressures.
