The US dollar index is down by 0.3% at 99.97 as of 7:51 a.m. ET.
"Participants appear to be growing increasingly frustrated with emerging priorities of the new US Administration," Marc Chandler, the global head of currency strategy, wrote in commentary.
"They want to hear more details and discussion of the tax reform, deregulation, and infrastructure plans," he continued. "However, the priority today is on authorizing the construction of a wall between the US and Mexico and possible action on immigration from"terror-prone" countries, according to press reports."
Separately, the FHFA House Price Index will be released at 9 a.m. ET.
As for the rest of the world, here's the scoreboard as of 7:47 a.m. ET:
- The Mexican peso is up by 0.4% at 21.4400 per dollar. Mexico's Economy Minister Ildefonso Guajardo told the Televisa network, "There are very clear red lines that must be drawn from the start" as he prepared to meet with US officials in Washington on Wednesday and Thursday. Asked whether the Mexican delegation would walk away from the negotiating table if the wall and remittances are an issue, Guajardo said: "Absolutely."
- The British pound is up by 0.5% at 1.2588 against the dollar. The currency is at its best level since mid-December. Still, a group of analysts at UBS argue that the pound's recent mini-rally will be short lived. "Our strategists are pricing in more weakness to come. Again, we've gone a long way, and yet the uncertainty that the Article 50 procedure is likely to bring further weakness," UBS Investment Bank's Chief European Economist Reinhard Cluse said.
- The euro is up by 0.2% at 1.0753 against the dollar. Earlier, the German Ifo Business Climate index came in at 109.8 in January, below expectations of 111.3, and below the prior month's reading of 111.0.
- The Russian ruble is little changed at 59.2213 per dollar, while Brent crude oil, the international benchmark, is down by 1.0% at $54.88 per barrel.
