EUR/USD advanced solidly above 1.1600 on Monday, trading near 1.1610 and appreciating approximately 0.4% for the day, as the U.S.-Iran peace framework diminished the safe-haven demand for the dollar and triggered risk-on flows across the market. The greenback declined to a 10-day low as the war premium that had supported it for weeks dissipated. The euro quickly filled the void following Trump’s confirmation that the Strait of Hormuz would reopen toll-free and the naval blockade would be lifted. The argument presented here challenges the typical instinctive response. This is primarily a move driven by dollar weakness, and in contrast to the usual relief bounce, the euro benefits from a solid fundamental advantage: a hawkish European Central Bank that has already raised rates and continues to indicate further increases, juxtaposed with a Federal Reserve constrained by disinflation from an oil crash, sluggish growth, and a president advocating for cuts. The policy divergence leans in favour of the euro. The issue lies within the chart. EUR/USD remains constrained beneath its 50-day and 200-day moving averages around the 1.1670 to 1.17 range. The RSI is positioned in the 30s, and the pair has recorded lower lows for two consecutive weeks. Until it reclaims 1.1700 on a closing basis, this represents a dollar-driven bounce within a downtrend — well-supported by the macro narrative, yet unconfirmed by the price action.
Strip the pair down, and Monday’s strength is predominantly a dollar narrative rather than one centred on the euro. The greenback had emerged as the most reliable safe haven during four months of conflict — each escalation headline, every threat from Hormuz, and every diplomatic setback drove capital into the dollar for protection. The peace framework abruptly pulled that bid in a single Sunday-night announcement, leading to a decline in the dollar index to a 10-day low as the safety premium diminished across the board. The mechanics are straightforward. The EUR/USD pair stands as the most actively traded in the global market, with approximately 31% of all foreign-exchange transactions involving the euro. Consequently, when the dollar experiences a decline, the euro naturally emerges as the primary beneficiary due to the significant volume of transactions. The risk-on rotation that boosted stocks, crypto, and even gold diminished the dollar’s defensive allure, while the euro benefited from the discount. The 0.4% daily gain may appear modest compared to equities surging between 1.5% and 2.4%, yet in the realm of currency movements, a 0.4% session in EUR/USD signifies a substantial repricing. This shift predominantly stemmed from the dollar’s performance rather than an influx of euro demand.
The second-order effect of the peace deal is where the real value resides. Crude experienced a significant decline on Monday, with WTI dropping below $80 for the first time in two months and Brent approaching $82.90, effectively removing the war premium from the energy market. Energy emerged as the primary catalyst behind the elevated inflation figures that prompted market speculation regarding a possible Fed rate increase before the year’s end — and a significant decline in crude oil prices swiftly alleviates those rate hike concerns. That is detrimental to the dollar, straightforward and clear. The greenback had garnered support from the expectation of a Federal Reserve compelled to tighten amidst persistent inflation, leading to an influx of investments in predictions of a rate hike that would have expanded the rate differential in favour of the dollar. The decline in oil prices has altered the economic landscape — lower crude costs alleviate inflationary pressures, strengthen the rationale for the Federal Reserve to maintain current rates or potentially reduce them in the future, and diminish the argument for the dollar’s strength based on rate differentials. Every dollar the barrel falls undermines the higher-for-longer narrative that supported the greenback, and EUR/USD rises as that support weakens.
The euro is not merely a passive recipient of dollar weakness on Monday; the ECB aspect contributes significantly as well. Governing Council member Martins Kazaks indicated earlier in the session that the central bank is prepared to increase rates, cautioning about potential inflationary pressures despite the finalisation of the U.S.-Iran deal. That statement reflects a strong stance on a day when the peace agreement could have provided support for the more conciliatory approach, and it emphasises the differing narratives that are influencing the pair. The context amplifies the impact of the remark. The ECB has taken action, implementing a rate hike on June 11 accompanied by assertive guidance. Additionally, it has revised its inflation forecasts upward — headline inflation is now projected at 3.0% for 2026 and 2.3% for 2027, while core inflation remains steady at 2.5% for both years. Euro-area inflation at 3.0% provides the hawks with the necessary leverage to maintain their stance, while Kazaks highlighting potential upside risks, even after the peace deal, signals to the market that the ECB’s actions are far from complete. A central bank continuing to tighten amidst above-target inflation creates a favourable environment for the currency, allowing the euro to benefit from a monetary policy that contrasts with the current trajectory of the dollar.
When comparing the two central banks, the divergence clearly emerges as the fundamental basis for the bullish argument. The ECB is increasing rates with assertive guidance and highlighting inflation risks. The Fed finds itself in a state of paralysis — Warsh steps into a committee grappling with inflationary pressures on one side and sluggish growth on the other, all while a president is vocally advocating for lower rates, which stands in stark contrast to the tightening measures that would typically be warranted. One bank is adopting a restrictive approach; the other is caught in a web of conflicting pressures with no clear direction. That gap provides EUR/USD with a fundamental support that a standard dollar-weakness rebound does not possess. Currency pairs operate based on rate differentials. When one side is increasing rates while the other remains stable or leans towards cuts, the calculations favour the currency that is tightening. The combination of Fed paralysis and ECB optionality on further hikes creates a meaningful divergence in the euro’s favour heading into the week. The catch is timing — the divergence represents a gradual advantage, while the Fed decision on Wednesday acts as an immediate catalyst, and the pair must navigate the short-term event before the underlying narrative can take hold.
