The Dow Jones Industrial Average edged up 0.09%, while the S&P 500 slipped 0.21% and the Nasdaq Composite dropped 0.53% in Monday's early session. US equities traded modestly lower as declines in major technology stocks offset the positive momentum generated by falling Treasury yields.

The semiconductor sector weighed heavily on stock index futures during Monday's trading. Micron Technology shares fell more than 3%, while Advanced Micro Devices and Broadcom retreated nearly 2% and about 1%, respectively. The iShares Semiconductor ETF also declined close to 2%. Other technology names followed the downward trend, with Coherent, Lumentum Holdings, and SanDisk all dropping 5%. Corning shares slid nearly 3%, and Seagate Technology pulled back approximately 4%.

Treasury yields moved lower after reports suggested the US Treasury Department may tap its General Account balances to fund bond repurchase operations. The 10-year Treasury yield declined 4 basis points to 4.7%, while the 30-year yield—which had briefly surpassed 5.3% last week to reach its highest level in nearly two decades—retreated 4 basis points to 5.23%.

Prior to these developments, US Treasury Secretary Scott Bessent had indicated last week that the department's bond buyback program in the coming months could exceed the $40 billion scale announced earlier this week. The initial policy announcement provided temporary relief at the long end of the US yield curve, but that positive momentum proved short-lived.

Rising global bond yields continue to pressure equity markets, with government debt yields in Japan, France, and Germany all climbing to multi-year highs. Meanwhile, concerns persist that ongoing US-Iran tensions could drive oil prices higher and intensify inflationary pressures.

"The Treasury is attempting to suppress long-end rates by issuing more short-term bills as a financing tool. However, this approach would tie the government's interest expenses more closely to the Federal Reserve's federal funds rate," said Peter Buchvar, Chief Investment Officer at One Point BFG Wealth Partners. "Fed Chair Kevin Warsh's speech on Friday may not address this directly, but it represents a new variable he must contend with."

Chair Warsh is expected to deliver remarks at the Federal Reserve's annual symposium in Jackson Hole, Wyoming. Additionally, investors will receive the July Personal Consumption Expenditures (PCE) price index—a key inflation gauge—scheduled for release on Wednesday.

The artificial intelligence sector also commands significant market attention this week, with Nvidia and Marvell Technology set to report earnings on Wednesday and Thursday, respectively. Bloomberg reported over the weekend, citing sources, that Nvidia has informed customers that server pricing featuring Vera Rubin and Blackwell chips will increase by more than 15%, adding context to the upcoming earnings releases.

The US dollar staged a modest rebound amid rising trade tensions with Canada. The dollar index gained 0.2% to 98.983, recovering from 98.557—a three-month low—hit last Thursday. The euro slipped 0.1% against the dollar to 1.16655, following a 0.9% weekly gain last week.

Bloomberg strategist David Savage noted that global equities could rally this week as investors reposition for a "dollar depreciation trade," with multiple catalysts on the horizon including Nvidia's earnings, the core PCE data, and the Jackson Hole central bank symposium.

"The dollar's reaction may depend on the scope and severity of sanctions," said Volkmar Baur, analyst at Commerzbank. He suggested that if multiple countries with economic ties to Iran are also affected by sanctions, the dollar could actually decline.

US-Canada trade relations continue to show signs of prolonged frost. The dollar gap higher against the Canadian dollar in early Asian trading reflects growing pessimism over near-term resolution of trade disputes. Canadian negotiation teams believe the likelihood of resuming talks before the US midterm elections remains low and are preparing a domestic support package to assist local businesses in navigating extended trade friction—measures that could potentially persist beyond the remainder of the current administration's term.

US Trade Representative Jamieson Greer acknowledged that it remains difficult to determine when negotiations might restart, confirming that no new talks are currently scheduled—a stance largely aligned with Ottawa's tempered expectations.
