- Major currencies including the euro, yen, pound, and antipodean dollars strengthened versus the U.S. currency

The greenback experienced a significant decline on Wednesday following President Donald Trump’s declaration of a two-week truce with Iran. Global currencies and digital assets rallied as market participants rotated out of defensive positions.
Trump had earlier issued threats of extensive strikes targeting Iran’s civilian infrastructure. He declared that “a whole civilization will die tonight” unless his conditions were satisfied, prompting widespread international criticism.
The truce came fewer than two hours ahead of Trump’s ultimatum deadline for Iran to reopen the Strait of Hormuz. Markets immediately pivoted toward risk-seeking behavior following the announcement.
The U.S. Dollar Index, measuring the currency’s performance versus six major peers, declined roughly 1% to 98.943. This marks its weakest reading since March 11 and positions it for its largest single-session decline since April 21, 2025.
The greenback typically draws capital flows during periods of geopolitical stress. As tensions subsided, appetite for the dollar as a defensive asset diminished.
The euro advanced 0.7% to $1.1677. The British pound increased 0.8% to settle at $1.3403. The Japanese yen appreciated 0.7% versus the dollar, changing hands at 158.50 per dollar.
The Australian dollar rallied 1.2% to $0.7063. The New Zealand dollar surged 1.1% to $0.5795. These currencies carry risk-sensitive characteristics, typically appreciating when market sentiment improves.
Digital Assets Participate in Broader Gains
Bitcoin rose 3.2% to $71,514.03. Ethereum gained 5.7% to $2,235.35. The advances occurred alongside broader movements into assets carrying higher risk profiles.
Cryptocurrency markets have shown growing correlation with global risk appetite, with Wednesday’s trading session demonstrating this relationship.
Energy Markets and Inflation Considerations
The possibility of resuming Strait of Hormuz shipping operations also pressured oil prices. The waterway represents a vital conduit for global petroleum transport.
Declining oil prices reduce concerns about rising inflation. When inflationary pressures diminish, the rationale for central banks to tighten monetary policy weakens. Reduced interest rates typically depress the dollar’s value, as international bonds become more appealing to foreign capital seeking superior returns.
Ray Attrill, head of FX strategy at National Australia Bank in Sydney, indicated the ceasefire could extend the risk-positive environment if shipping lanes reopen. However, he cautioned that exchange rates remain susceptible to sudden shifts during the 14-day truce period.
“Markets still need to proceed with a degree of scepticism,” Attrill said.
The Dollar Index has now declined for three consecutive sessions. The ceasefire has delivered a near-term catalyst for markets, though strategists emphasize that developments over the coming fortnight will prove critical.
