The U.S. dollar recorded its poorest monthly performance in nearly a year during April. As market expectations grew for a de-escalation of tensions between the U.S. and Iran and prospects for peace negotiations improved, investors reduced their bets on safe-haven assets, contributing to the dollar's weakness. Data showed that the Bloomberg Dollar Spot Index fell by 1.9% over the month, its largest decline since June of last year. Much of the drop occurred after a ceasefire agreement was reached between the U.S. and Iran earlier in the month. However, the dollar's decline moderated as oil prices climbed again recently and markets renewed bets that the Federal Reserve may raise interest rates next year. Analysts noted that the dollar had strengthened significantly in March due to escalating Middle East conflicts, but its safe-haven appeal diminished noticeably as the situation eased. U.S. President Donald Trump recently stated that port blockades against Iran would not be lifted until a nuclear agreement is reached, while military options remain under consideration, indicating ongoing uncertainty. On Thursday, the dollar fell by 0.8% at one point after Japanese authorities intervened in the currency market to support the yen. At the same time, Brent crude futures retreated from a four-year high, further weakening support for the dollar. That day, G10 currencies broadly strengthened, with the Japanese yen leading gains, while the Swiss franc, Australian dollar, and New Zealand dollar each rose more than 1%. Interest rate expectations also influenced the dollar's movement. The Federal Reserve held rates steady and suggested that economic impacts from the war could limit future rate cut possibilities, prompting markets to increase bets on a rate hike next year, which temporarily supported a dollar rebound. In contrast, other major central banks have taken clearer stances on fighting inflation. Markets anticipate that the Reserve Bank of Australia and Norges Bank may raise rates sooner, driving the Australian dollar and Norwegian krone to gains of over 4% this month. Strategists at Deutsche Bank noted that energy price shocks could prompt several central banks to accelerate policy tightening, while the Fed's relatively cautious approach has weakened the dollar's status as a high-yield currency. Against a backdrop of elevated energy prices, currencies linked to commodities have performed more strongly. Analysts recommend shorting the U.S. dollar while going long on the Australian dollar, Norwegian krone, and emerging market currencies such as the Brazilian real and Mexican peso, which are tied to commodity prices. Meanwhile, the euro also rebounded in April. Although Europe's high reliance on Middle Eastern energy had previously pressured the euro as oil prices rose, the European Central Bank's increasingly hawkish stance helped the euro gain about 1.6% against the dollar this month. Nathan Thooft, Senior Portfolio Manager at Manulife Investment Management, suggested that the dollar may continue to face pressure going forward, but given the relative strength of the U.S. economy and persistent global uncertainties, declines are likely to be limited, with the currency expected to trade in a range-bound pattern. Viraj Patel, Strategist at Vanda Research, also pointed out that if markets further reinforce expectations that U.S. rates will remain high for longer, the dollar could rebound; however, in the absence of a clear catalyst, it is likely to maintain a sideways trend.
