Dollar holds firm as Middle East ceasefire hopes rise

The dollar largely held steady on Wednesday as investors grew cautiously optimistic about prospects ​for a ceasefire in the Middle East conflict, though mixed signals kept markets on edge.

The yen has recovered from this year's ‌low of 160.46 per dollar, moving back through the psychologically important 160 level that had fanned concerns about intervention by Japanese authorities. The euro hit more than a one-week high.

"Looking at the market as a whole, expectations for a ceasefire are basically rising, so I think the reversal of the long-running 'buy dollars, sell yen' trade is likely to ​continue," said Sho Suzuki, market analyst at Matsui Securities.

Still, Suzuki added the move has not become a one-way shift into the yen ​gaining momentum due to concerns that the conflict may not wind down easily.

The dollar index , which measures the greenback ⁠against a basket of currencies including the yen and the euro, was last down 0.03 percent at 99.70, slipping to a one-week low. The euro edged ​up 0.2 percent at $1.1574.

The Japanese yen was flat against the greenback at 158.63 per dollar. Sterling strengthened 0.29 percent to $1.3261.

The White House said US President Donald Trump would ​address the nation "to provide an important update on Iran" at 9 p.m. EDT on Wednesday (0100 GMT on Thursday). The president said earlier in the day the US could end its military campaign against Iran within two to three weeks, while Secretary of State Marco Rubio told Fox News Washington could see the "finish line" in the Iran war.

At the same time, ​there were signs of escalation in the conflict. US Defense Secretary Pete Hegseth said the next few days in the war against Iran would be ​decisive and warned Tehran that the conflict would intensify if it did not make a deal.

The Wall Street Journal also reported the United Arab Emirates is preparing to help ‌the US ⁠and other allies open the key Strait of Hormuz waterway by force. The Israel Defense Forces said a surface-to-air missile downed an Israeli military drone during operational activity in southern Lebanon overnight, and missiles and drones continued to strike across the Gulf.
