The dollar clung to modest gains against major currencies on Tuesday, as investors' appetite for riskier assets remained subdued amid evolving developments in the Middle East conflict.

The dollar, which surged in recent sessions after U.S.-Israeli strikes on Iran sent oil prices soaring, gave up some of those gains after President Donald Trump suggested on Monday the conflict could end sooner than expected.

Trump said the war could end well before the timeline he initially laid out, but threatened to escalate attacks should Tehran block oil shipments from the Strait of Hormuz.

Trump's comments helped ease concerns, reducing buying pressure on the dollar and sending oil prices down about 15% on Tuesday, a day after they soared to their highest levels since 2022.

"I think this is largely a reflection of the FX complex reacting to the easing in energy prices, which if prolonged could lessen the inflationary implications of the current commodity shock, thus lessening some degree of pressure in terms of heavy energy-importer economies," Michael Brown, senior research strategist at Pepperstone in London, said.

The euro EUR= was 0.1% lower on the day at $1.16252 after sinking to a more than three-month low of $1.1505 in the prior session. The dollar was 0.1% up against the yen at 157.86. JPY=

Some strategists warned optimism about a quick resolution may be premature.

"We're still in a market where almost everything is still tightly correlated to developments in the crude complex, and where participants retain a laser-like focus on incoming geopolitical headlines," Pepperstone's Brown said.

Iran's Revolutionary Guards dismissed Trump's remarks as "nonsense" and said the blockade would continue until attacks from the U.S. and Israel end.

Meanwhile, G7 energy ministers stopped short of agreeing on a release of strategic oil reserves on Tuesday and instead asked the International Energy Agency to assess the situation before acting.

The pound was 0.1% lower against the dollar at $1.34265.

The pound has been pressured by subdued economic data and domestic political turbulence in recent weeks.

The Canadian dollar rose about 0.1% to $1.3575 on Tuesday, and the yield on benchmark government debt climbed, as the firming risk appetite helped make up for falling crude prices.

"The CAD has appreciated 2% since November, largely a reflection of rising crude oil prices. Despite persistent risks from U.S. tariffs, stronger oil prices should bolster the loonie," strategists at global macro research and advisory firm Numera Analytics said in a note.

"Our forecast points to appreciation from 1.37 to 1.33 per USD over the next 12 months," they wrote.
