The greenback experienced a significant decline on Wednesday following President Donald Trump’s announcement of a temporary two-week truce with Iran. This development triggered gains across global currencies and digital assets as market participants rotated out of defensive positions.
Prior to the ceasefire announcement, Trump had issued stark warnings of extensive strikes targeting Iranian civilian infrastructure. His statement that “a whole civilization will die tonight” unless his conditions were satisfied generated widespread international criticism.
The truce declaration came with less than two hours remaining before Trump’s ultimatum for Iran to reopen the strategically vital Strait of Hormuz. Markets immediately responded with a decisive shift toward riskier assets.
The Dollar Index, which measures the U.S. currency’s performance against a basket of six major rivals, declined roughly 1% to settle at 98.943. This marks the index’s weakest reading since March 11 and positions it for its most substantial daily retreat since April 21, 2025.
Typically, the greenback benefits from capital inflows during periods of geopolitical instability. As tensions subsided, the dollar’s appeal as a refuge weakened considerably.
The euro appreciated 0.7% to reach $1.1677. Sterling advanced 0.8%, touching $1.3403. Japan’s yen firmed up 0.7% against its American counterpart, changing hands at 158.50 per dollar.
Australia’s dollar climbed 1.2% to $0.7063. New Zealand’s currency jumped 1.1% to $0.5795. These commodity-linked currencies are particularly sensitive to shifts in risk appetite, typically advancing when market optimism increases.
Digital Assets Join Broad-Based Rally
Bitcoin rose 3.2% to trade at $71,514.03. Ethereum posted a 5.7% gain, reaching $2,235.35. The cryptocurrency advances mirrored the wider market rotation into higher-risk investments.
Digital currency markets have shown growing correlation with global risk sentiment in recent months, with Wednesday’s trading session exemplifying this relationship.
Energy Markets and Inflation Implications
Expectations surrounding the potential reopening of the Strait of Hormuz also pressured oil prices lower. This waterway serves as a crucial conduit for international petroleum shipments.
Declining energy costs help alleviate inflation pressures. As inflation expectations moderate, central banks face reduced pressure to implement interest rate increases. Softer rate expectations typically weaken the dollar, as international investors seek higher-yielding opportunities in overseas bond markets.
Ray Attrill, head of foreign exchange strategy at National Australia Bank in Sydney, noted that the ceasefire could sustain the rally in risk assets if the shipping lane reopens. However, he cautioned that currency markets remain susceptible to sudden reversals throughout the 14-day ceasefire period.
“Markets still need to proceed with a degree of scepticism,” Attrill said.
The Dollar Index has now posted losses for three consecutive sessions. While the ceasefire has provided near-term support to markets, strategists emphasize that the outlook over the coming fortnight remains uncertain.
