U.S. stock futures opened lower Tuesday as Wall Street contended with geopolitical tensions between the U.S. and Iran, surging oil prices, and rising Treasury yields that fueled inflation concerns. Key global bond yields reached multi-decade highs, reflecting widespread anxiety, while investors also await crucial economic data and Home Depot earnings.
U.S. stock futures experienced a downturn early Tuesday, extending Wall Street's losing streak from the start of the week. Renewed tensions between the U.S. and Iran, coupled with escalating inflation concerns, drove Treasury yields higher and pressured equity markets.
Dow Jones Industrial Average futures saw a decline of 73 points, while S&P 500 futures fell 0.32%, and Nasdaq-100 futures dropped 0.59%.

Across Asia, market performance was mixed. South Korea's benchmark Kospi surged 1.9% on Tuesday, but Japan's Nikkei 225 ended 0.94% lower. Australia's S&P/ASX 200 posted a modest gain of 0.19%, while Hong Kong's Hang Seng Index slipped 0.19%, and the CSI 300 lost 0.12%.
The pullback in U.S. futures followed a challenging session for stocks on Monday, primarily driven by a more than 2% jump in oil prices. This surge was sparked by uncertainty surrounding a U.S.-Iran ceasefire that expired, with negotiations stalled and President Donald Trump issuing strong warnings about potential military action against Oman if it intervened.
The rising cost of oil exacerbated inflation fears, pushing longer-dated Treasury yields to multi-year highs. Notably, the 30-year Treasury bond yield reached a level not seen since June 2007.
On Monday, both the Dow and S&P 500 led the declines, each dropping 0.5%. The Nasdaq demonstrated relative resilience, though it still retreated by 0.3%.
Despite the recent turbulence, Sonali Basak, chief investment strategist at iCapital, expressed confidence in the market's remaining upside, particularly as the rally diversifies beyond the technology sector. "You look around and there's still more room to run," Basak remarked in an interview on CNBC's "Closing Bell." She noted that the S&P Equal Weight index has yet to outperform the Nasdaq or the SOXX, suggesting underappreciated value elsewhere.
Investors are also keenly awaiting key economic data for July, including import and export pricing figures, housing starts, and pending home sales. Additionally, Home Depot is scheduled to release its second-quarter earnings report before the market open.
U.K. unemployment rate holds steady
In the United Kingdom, the unemployment rate remained at 4.9% during the three months ending in June, slightly above the 4.8% consensus forecast. The number of payrolled employees increased by 83,000 in the period, falling short of the Reuters poll estimate of 129,000. Average weekly earnings grew 4.1% year-on-year, aligning with expectations.
Following the jobs report, the pound traded 0.13% lower against the dollar at $1.35.
Global bond yields rise to record levels
Resurgent inflation anxieties are driving government borrowing costs higher globally, with many longer-maturity bond yields hovering near multi-decade peaks. Early Tuesday, U.S. 30-year Treasury yields climbed 1 basis point to approximately 5.324%, marking their highest level since 2002.
Japanese long-dated government bond yields neared levels last seen in May, which were 40-year highs. Germany's 30-year bond yield reached its highest point since 2011, while its British counterparts approached a multi-decade high. French 30-year government bond yields also ticked up to a post-2008 high.

As of 6:30 a.m. London time (1:30 a.m. ET), European stock futures largely indicated a negative open. Futures tied to the regional Stoxx 50 were down 0.5%, German DAX index futures were about 0.6% lower, while French CAC 40 and FTSE 100 futures remained flat.
Yield on 30-year Treasurys hovers near 19-year high as bond sell-off deepens
U.S. Treasury yields continued their ascent on Tuesday, with longer-dated yields maintaining positions near multi-decade highs amid an ongoing government bond sell-off. The 30-year Treasury yield advanced approximately 1 basis point to 5.32%, hovering around its highest since 2007. The 20-year yield climbed to 5.316%, and the benchmark 10-year Treasury yield added roughly 1.2 basis points to 4.736%.
Concerns over the U.S. fiscal outlook and a substantial supply of government debt, combined with elevated oil prices and renewed geopolitical tensions, have driven yields upward. Mark Newton, a technical strategist at Fundstrat, predicted that "Long-term yields look likely to push up to 5.60-5.70% and likely move up at a quicker pace than normal."
He also highlighted Japan's recent economic data, where weaker-than-expected growth was accompanied by a hotter-than-expected GDP deflator. The subsequent rise in Japanese government bond yields impacted U.S. Treasurys, further lifting longer-duration yields.
Oil rises amid worries over renewed hostilities as U.S.-Iran ceasefire lapses
Oil prices gained on Tuesday amidst growing concerns about supply disruptions and the potential for renewed conflict in the Middle East. This followed President Donald Trump's decision not to extend the Iran ceasefire. Futures for international benchmark Brent crude for October delivery rose 0.48% to $91.31 a barrel, while U.S. West Texas Intermediate futures for September advanced 0.62% to $85.02 per barrel.
President Trump's Monday comments, stating the U.S. would "bomb the s--- out of" Oman if it "gets in the way," further fueled worries about escalating regional tensions. José Torres, a senior economist at Interactive Brokers, noted that "Crude prices are rising on renewed geopolitical tensions triggered by President Trump threatening Oman with military strikes and communicating that he is in no rush to end the Iran war." Torres also cited a "fresh burst of violence in Lebanon" as a contributing factor to market participants' concerns.
Yen holds steady at 159 per dollar; U.S. has ample firepower for more yen intervention, Macquarie says
The Japanese yen stabilized around 159 against the dollar on Tuesday, having surrendered a significant portion of its gains from last month's coordinated U.S.-Japan intervention. Macquarie estimated that U.S. authorities sold approximately $500 million worth of euros for yen on July 31, a modest amount compared to Japan's estimated $85 billion spent buying yen with dollars over July 30 and 31.
Gareth Berry, Macquarie's head of FX and rates strategy, suggested that Washington's intervention primarily served as a signal to markets rather than being impactful due to its size. However, Berry indicated that the relatively small U.S. operation leaves Washington with substantial capacity for further intervention should the yen weaken again. Macquarie estimates the U.S. Treasury and Federal Reserve hold another $25.9 billion in euro-denominated reserves for potential EUR/JPY deployment, and an "almost limitless" capacity for direct USD/JPY intervention.
China 10-year government bond yield gap widens with U.S. Treasurys
The yield spread between China's 10-year government bonds and U.S. 10-year Treasurys is expanding once more, highlighting increasing economic divergence between the world's two largest economies. The spread reached 303 basis points on Monday, matching July 31 levels and approaching the 315 basis points recorded in January 2025 (Wind Information data since 2007).
As China's economy contends with weak domestic demand, its 10-year government bond yield has consistently traded below that of the U.S. 10-year Treasury yield since 2022. Weaker-than-expected Chinese economic data released Monday has heightened expectations for further policy easing, which could further widen this yield spread.
Conversely, in the U.S., Treasury yields rose, with the 30-year yield hitting its highest since June 2007, as rising oil prices compounded investor concerns about elevated inflation and government debt levels.
South Korea stocks rise at open, Japanese benchmarks fall
Asia-Pacific markets displayed a mixed performance on Tuesday, with South Korean stocks defying a broader regional decline after a holiday break. South Korea's benchmark Kospi jumped 2%, driven by strong gains from chip giants Samsung Electronics and SK Hynix, which climbed 3% and 5% respectively.
Meanwhile, Japan's Nikkei 225 was down 0.9%, and the Topix declined 0.28%. Australia's benchmark S&P/ASX 200 opened flat.
Asia-Pacific markets set to open lower as investors assess U.S.-Iran tensions
Asia-Pacific markets were poised for a lower open on Tuesday as investors reacted to escalating U.S.-Iran tensions. President Donald Trump ruled out extending a 60-day ceasefire with Iran, which had provided a fragile truce, and also issued threats of military action against Oman.
Japan's Nikkei 225 Chicago futures contract was at 68,990, with its Osaka counterpart at 68,970, both below the index's previous close of 69,220.25. Hong Kong's Hang Seng index futures last traded at 25,355, beneath the benchmark's close of 25,453.23.
Futures for Australia's S&P/ASX 200 were at 8,976, compared to the index's last close of 9,073.2.
Trump commented that informal discussions were ongoing with Iran's Revolutionary Guard but that he was "not in a hurry" to finalize an agreement. He characterized the Iranians as "good poker players, but they're dying." Hours later, he confirmed to reporters that he would not seek to extend the temporary truce.
L3Harris ousts CEO
Shares of defense contracting giant L3Harris Technologies fell over 4.5% in regular trading after the company announced the removal of CEO Chris Kubasik. L3Harris stated that Kubasik engaged in "certain conduct ... that was not consistent with the values of the Company." Sam Mehta has been appointed as the new chief executive officer and president. Following Monday's close, shares saw a marginal recovery.
Stock futures open little changed
Dow Jones Industrial Average futures traded 32 points lower. S&P 500 futures and Nasdaq-100 futures also registered marginal declines.
