Market Talks covering the impact of U.S. Politics and White House policies on companies and markets. Published exclusively on Dow Jones Newswires throughout the day.

0413 ET - The dollar is at risk of falling ahead of remarks from Treasury Secretary Scott Bessent and the Federal Reserve's Jackson Hole symposium, MUFG Bank's Derek Halpenny says in a note. Bessent could provide information on fiscal consolidation plans later Monday after the Treasury announced increased buybacks of long-dated securities last week. Fed Chair Kevin Warsh is due to speak at Jackson Hole on Friday. Warsh could continue to provide little signals about future policy, Halpenny says. "That could see the long-end of the bond market suffer especially if by then there has been no credible measures announced on fiscal consolidation." The DXY dollar index last trades up 0.2% at 98.966, having reached a three-month low of 98.557 Thursday. (renae.dyer@wsj.com)

0337 ET - Oil prices fall more than 1.5% as investors await details on expected U.S. sanctions on Iran. "The move could further tighten global oil supplies, with Iranian exports already disrupted and offers to China reduced," analysts at Saxo Bank say. In early European trading, Brent crude is down 1.7% to $91.01 a barrel, while WTI futures slide 2.1% to $85.20 a barrel. Both benchmarks closed last week more than 6% higher as talks to reopen Hormuz hit a stalemate and President Trump announced plans to tighten the economic squeeze on Tehran. U.S. Treasury Secretary Scott Bessent is set to ​hold a press conference at 2 p.m. Eastern time when he is expected to announce details about new economic sanctions against Iran.

0336 ET - The Canadian dollar falls after trade talks between the U.S. and Canada collapsed. New U.S. tariffs against Canada came into effect at the weekend following the breakdown of negotiations on Friday, while Canada said it would impose reciprocal levies. "As a smaller, more open economy, Canada has more to lose from this, but Prime Minister Mark Carney seems to have opened the door to more fiscal stimulus to support affected business," ING's Chris Turner says in a note. The U.S. dollar rises 0.5% to a five-day high of 1.3831 Canadian dollars and ING sees scope for it to reach 1.3910 before U.S. dollar sellers return. (renae.dyer@wsj.com)

0206 ET - The fact that the U.S. Treasury is buying bonds to lower yields could prevent markets from fully pricing inflation and fiscal risk, and from reacting fully to Fed policy decisions, says Ipek Ozkardeskaya, strategist at Swissquote. As such, it could make the Fed's job of bringing inflation back toward its 2% target harder--something that Fed Chair Kevin Warsh probably wants to avoid. He won't want to look like a fool in front of the entire world, she adds. This week's Jackson Hole gathering might bring some clarity on how the Fed will fit into the administration's plans, she says. (james.glynn@wsj.com; @JamesGlynnWSJ)

0134 ET - The U.S. Dollar Index remained heavy near 98.8 points in Asia, says Samara Hammoud, foreign-exchange strategist at CBA. Concerns about U.S. fiscal dominance, the sustainability of government debt, and U.S. dollar debasement appear set to continue to weigh on the currency this week, she adds. Treasury Secretary Scott Bessent has raised expectations that a budget consolidation program will be released this week. However, the poor experience with DOGE, the Department of Government Efficiency, in 2025 illustrates how difficult it is to rein in government spending or raise taxes, Hammoud adds. A modest consolidation would disappoint market expectations and further weigh on the U.S. dollar, she says.
