Temporary Truce Between US and Iran Sends Dollar Lower
Market sentiment improved markedly following news of a temporary ceasefire between the United States and Iran. While doubts over the prospects for the long-term peace still loom, the positive shift in risk appetite has placed significant downward pressure on the US dollar.
The US Dollar Index (DXY) fell from around the 100.00 level to 99.06 on Wednesday (April 8), as investors moved into riskier assets following the announcement of a two-week ceasefire agreement between Washington and Tehran. The development reduced demand for the dollar's traditional safe-haven appeal.

US President Donald Trump expressed his willingness to delay planned military strikes against Iran for two weeks. He also opened the door for dialogue regarding the 10-point demands from the Iranian side, provided that access to the Strait of Hormuz is reopened.
In an official statement, Trump described the agreement as a reciprocal step that reflects the achievement of key military objectives while creating an opportunity for broader peace negotiations across the Middle East.
The announcement came just ahead of the expiration of his previously issued ultimatum. From the Iranian side, Foreign Minister Abbas Araghchi confirmed that a preliminary understanding had been reached through mediation efforts led by Pakistan. He stated that the suspension of US military actions would be met with a halt to Iran’s defensive operations.
Araghchi also indicated that shipping lanes through the Strait of Hormuz would be partially reopened during the ceasefire period, coordinated under the supervision of Iranian military authorities.
Financial markets reacted swiftly to the geopolitical shift, particularly across energy and foreign exchange sectors. Brent crude prices briefly plunged by as much as 15% and were last trading near $97.20 per barrel. Meanwhile, major rivals of the US dollar strengthened.
The AUD/USD and NZD/USD pairs each recorded an increase of about 1.2%, while USD/JPY weakened by about 0.7% to trade near the 158.29 level.
Analysts: Long-Term Peace Still Uncertain
Further negotiations between the United States and Iran will be held in Islamabad, Pakistan. Although market participants welcomed the move, analysts caution that long-term stability remains far from assured.
Ray Attrill, Head of FX Strategy at National Australia Bank, noted that the reopening of the Strait of Hormuz could reinforce the ongoing risk-on trend. However, he cautioned that many factors still need to be confirmed in the next two weeks, so the market should remain cautious and maintain a skeptical stance.
