EUR/USD rebounds as dollar safe-haven bid fades

The euro is gaining ground on 1 April, but the question hanging over currency markets is whether this is a genuine turning point or a relief rally built on fragile foundations. A single report — that President Trump has indicated the campaign against Iran could end sooner than previously suggested — has unwound weeks of safe-haven dollar demand, yet the structural forces that drove EUR/USD to a three-month low remain firmly in place.

The pair gained around half a percent to trade back in the mid‑$1.15s, partially reversing a March that ranks among the worst months for the euro in nearly a year.

A brutal quarter for the euro

The euro fell roughly around 2.5% against the dollar in March, its steepest monthly decline since July, and shed close to 2% over the first quarter — the worst quarterly performance since Q3 2024. That erosion came almost entirely from a single source: Europe's acute vulnerability to elevated oil prices.

When US and Israeli strikes on Iran triggered a surge in Brent crude in late February, the euro became one of the hardest-hit major currencies. Unlike the United States, which has been a net energy exporter for nearly a decade, the eurozone is heavily dependent on crude imports. Every dollar added to the oil price functions as a tax on European growth, and with Brent pushing above $100 per barrel for much of March, traders aggressively reduced euro exposure. The dollar, simultaneously benefiting from safe-haven flows and its relative insulation from energy disruption, posted a gain of around 2.5% over the month — also its best since July.

The ECB's impossible position

The European Central Bank's stance has added another layer of complexity. The ECB held its deposit rate at 2.0% at its February meeting, marking the fifth consecutive hold, and March projections reinforced a data-dependent, meeting-by-meeting approach. Analysts note that ECB staff projections leave limited room for further euro strength without risking inflation undershooting the 2% goal, while a prolonged oil shock could simultaneously weaken growth.

That stagflationary bind left the ECB with limited room to manoeuvre. Futures markets had, at points in March, begun pricing the possibility of ECB rate hikes as early as July — a dramatic reversal from the rate-cut expectations that opened the year. Analysts at JPMorgan noted that currency moves to date had not yet reached levels the ECB would consider alarming, but cautioned that deteriorating growth data or a sharper euro decline could change that assessment quickly.

Technical picture: a bounce from damage

From a technical standpoint, EUR/USD had approached support near $1.1505 — a more than three-month low — before de-escalation reports triggered the current recovery. The bounce toward $1.1532–1.1543 has brought the pair closer to near-term resistance. The dollar index, holding near 99.96–100.00, remains elevated relative to its pre-conflict levels, suggesting the market has not fully abandoned its preference for the greenback.

The yen staged a parallel recovery alongside the euro, with USD/JPY easing back from recent highs in the high‑150s after Japanese officials repeated warnings against speculative yen selling and hinted they were watching markets closely.

Contradictory signals cloud the outlook

Strategists note that the pair has tracked oil prices with unusual sensitivity throughout the conflict, and any renewed escalation could rapidly reverse today's gains. That risk appeared live on 1 April itself: senior U.S. officials warned that the next few days would be decisive and threatened intensified strikes if Tehran did not stand down — comments that landed on the same day as reports of Trump’s willingness to wind down operations. Iranian forces were also reported to have attacked an oil tanker in Gulf waters, a reminder that physical disruption to shipping has not abated.

Analysts have described EUR/USD as caught between two forces. The dollar's safe-haven premium built during the Iran conflict is beginning to deflate. But Europe's energy import dependence means that even a partial Strait of Hormuz reopening may not be sufficient to fully restore confidence in eurozone growth.

What traders are watching next

The March US non-farm payrolls report, due 3 April, will be the first major read on how labour markets have absorbed the oil shock. March CPI, scheduled for 10 April, will clarify whether energy prices have fed through to core inflation. The ECB's late-April policy meeting could shift the Governing Council's tone on inflation risks and set the trajectory for EUR/USD through Q2.

Beyond data, any development in the Iran conflict — ceasefire progress or renewed escalation — may prove the single most decisive factor for the pair. For now, the euro's recovery reflects hope rather than resolution. The conditions that drove it to recent lows have not materially changed. What has changed is the narrative — and in currency markets, that can be enough, until it is not.
