The strength of the dollar in March is a typical repricing of global macro-assets amid the shocks of "war-energy-growth-policy" variables. On the surface, it appears as a return to safe-haven assets; on a deeper level, it reflects that even as global growth expectations weaken, oil prices surge, and policy paths are disrupted, capital still tends to embrace U.S. currency and assets. Bloomberg summarized this trend as the Bloomberg Dollar Spot Index recording its best monthly performance since July last year, while Reuters emphasized that this rebound so far is merely a "modest recovery," insufficient to completely overturn the long-term narrative of a weaker dollar over the past year.
How War Changes Dollar Logic
In recent years, structural concerns about the dollar mainly stemmed from U.S. fiscal deficits, policy uncertainty, and discussions of global de-dollarization. However, the situation with Iran has brought the market back to a more traditional framework in a short time: when global risk assets decline and energy-importing countries face greater inflation shocks, the dollar still enjoys a natural advantage. On March 4, Reuters pointed out that this dollar upswing did not begin as a "typical safe haven" but was rather like a forced covering of previous short positions; by late March, as oil prices stayed above $100 and risk assets were under pressure, this covering gradually evolved into broader safe-haven buying and pricing of energy advantages.
Cross-Asset Implications
This dollar rebound is not an isolated event. It coincided almost simultaneously with the rise in crude oil, the erratic performance of gold and U.S. bonds, and the pressure on global stock markets. Reuters wrote quite plainly on April 1: When the market believes that the war may be nearing its end, the entire trading logic is "played in reverse"—oil prices fall, stock markets rise, bonds rebound, and the dollar weakens. In other words, the current dollar is not an asset driven by unilateral U.S. economic strength but a link in the entire war trading chain. As long as this chain reverses, the direction of the dollar will quickly turn around.
Medium to Long-Term Outlook
In the medium to long term, the conclusions from Reuters' foreign exchange survey remain cautious: the recent dollar rebound may gradually fade, with the euro expected to rise to 1.20 over the next year; analysts also warn that the U.S. is not entirely immune to the impact of high oil prices, and a weaker labor market along with consumer real income pressures may ultimately limit the dollar's further appreciation potential. This implies that the dollar's "comeback" is better understood as a condition-driven, event-driven resurgence, rather than an already confirmed long-term supercycle. If the Middle East situation cools and oil prices continue to fall from March highs, the safe-haven and energy premiums enjoyed by the dollar are likely to diminish simultaneously.
