0654 GMT - The dollar edges higher as U.S.-Iran tensions persist. Treasury Secretary Scott Bessent said in an opinion piece for the Financial Times that an "economic D-Day" was coming for Iran. Bessent is expected to provide details on sanctions at a news conference later in the day. "The dollar's reaction is likely to depend on the scope and severity of the sanctions," Commerzbank's Volkar Baur says in a note. The dollar could fall if several countries with economic ties to Iran are affected by sanctions, he says. The DXY dollar index rises 0.1% to 98.871, having reached a three-month low of 98.557 Thursday after the Treasury announced increased buybacks of long-term debt. (renae.dyer@wsj.com)

0606 GMT - 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)

0603 GMT - Bond markets remain vulnerable as oil prices are still elevated and fiscal fears are mounting, Commerzbank's Hauke Siemssen says in a note. "Global bond markets remain vulnerable with yields across the curves testing multi-year highs," the rates strategist says. While this morning's consolidation is encouraging, a lasting turnaround seems unlikely for now as there is no easy fix to the underlying drivers, he says. The strategist expects input for the markets from U.S. PCE inflation data and guidance from the Kansas City Fed's annual Jackson Hole symposium this week, adding that the data and the symposium "should become intriguing."

0600 GMT - RBC BlueBay Asset Management continues to advocate for inflation-linked bonds and swaps to outperform while the prospect of a peace deal in the Middle East is elusive, says fixed income head Mark Dowding in a note. Money markets price in a full 25-basis-point Federal Reserve rate hike in December, according to LSEG. "In the Middle East, hopes for a peace deal continue to diminish and it appears that we are set to remain in a grey zone for an extended period, with trade flows through the Strait of Hormuz staying at a fraction of the levels seen prior to the start of the war," Dowding says.

0546 GMT - U.S. Treasury yields decline in Asian trade, but nonetheless remain at elevated levels as oil prices also move lower. "Last week it was all about U.S. Treasurys and [Treasury Secretary Scott] Bessent's announcement on increased long-end buyback, prompting a mid-week rally," Danske Bank's Jesper Fjarstedt says in a note. "But as markets digested this and concluded that the structural drivers remain the same, the initial move was reversed and long-dated yields closed the week broadly unchanged," the senior analyst says. The 10-year Treasury yield falls 2.2 basis points to 4.714%, while the 30-year yield, which hit a 19-year high of 5.337% last week, declines 2.7 basis points to 5.248%, according to Tradeweb. Brent falls 1.36% to $93.11 per barrel. (emese.bartha@wsj.com)

0534 GMT - Federal Reserve Chairman Kevin Warsh is likely to argue for reducing the Fed's use of forward guidance, which he views as a source of past policy mistakes, Barclays rates strategists say in a note. At the Kansas City Fed's annual symposium at Jackson Hole between Aug. 27 and Aug. 29, Warsh may also provide insights on balance sheet policy, they say. They also expect Warsh to emphasize long-run drivers of the economy, particularly productivity trends and their effects on potential growth. Warsh is unlikely to provide near-term policy guidance, but markets will look for clarity on how the FOMC intends to return inflation to the 2% goal, the strategists say. Warsh is more likely than not to affirm that rate hikes are possible if inflation fails to improve. (emese.bartha@wsj.com)

0534 GMT - 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. (james.glynn@wsj.com; @JamesGlynnWSJ)

0523 GMT - The recent rise in commodity prices can't serve as the sole explanation for the latest decline in bond prices, LBBW's Elmar Voelker says in a note. A key factor contributing to this assessment is the observation that most upward pressure on yields on both sides of the Atlantic was concentrated in the long-term segments, the senior fixed income analyst says. A clear trend toward rising term premiums has continued in recent days, apparently on a global scale, he says. The yield on the 10-year German Bund exceeded 3.25% for the first time since early summer 2011 and this can't be explained solely by growing fears of inflation, he says. (emese.bartha@wsj.com)

0523 GMT - The German 10-year Bund yield has already reached Societe Generale rates strategists' fourth-quarter target of 3.25%, but this isn't the end of the selloff, they say in a note. "Term premium rebuilding still has a long way to go, with the 10-year Bund term premium remaining well below pre-QE [quantitative easing] levels," they say. This keeps Societe Generale's 3.40% mid-2027 target firmly in place and leaves the 3.60-3.75% range increasingly plausible by late 2027, they say. The 10-year Bund yield closed at 3.25% on Friday, according to Tradeweb. (emese.bartha@wsj.com)

0517 GMT - The U.S. Treasury's decision last week to increase buybacks of long-end securities, alongside other recent Treasury actions, is a signal that the U.S. Treasury is uncomfortable with current yield levels, J.P. Morgan analysts say in a note. "Absent genuine fiscal consolidation, however, we doubt such measures can deliver a durable decline in yields and could actually lift term premium if U.S. Treasury issuance becomes more opportunistic and less predictable," they say. With risks of a further U.S. selloff, thin summer liquidity and persistently high energy prices, J.P. Morgan analysts prefer to remain cautious on European duration. They close longs in 10-year Bunds but keep the cross-market longs versus U.S. Treasurys and remain neutral on U.K. gilts.
