Crude prices rebound as Washington threatens tougher sanctions on Tehran, while Asian stocks struggle and investors turn their attention to Nvidia’s closely watched results….
Oil prices moved higher in early Asian trading on Tuesday as investors weighed the latest escalation in Washington’s economic campaign against Iran and the continuing uncertainty surrounding the Strait of Hormuz.
Brent crude rose 0.5 per cent to about $92.59 a barrel, while West Texas Intermediate gained 0.7 per cent to $85.57. The modest rebound came a day after both benchmarks suffered losses of more than two per cent as markets assessed the possibility that the United States could favour economic pressure over immediate military action.
The latest developments have added another layer of uncertainty to financial markets, which are already dealing with persistent inflation concerns, elevated bond yields and growing questions over whether the enormous valuations attached to technology and artificial intelligence companies can be sustained.
US steps up pressure on Tehran
Washington has signalled a much tougher approach towards Iran, with US Treasury Secretary Scott Bessent describing the latest campaign as an attempt to cut off the economic channels supporting the Iranian government.
Bessent said the United States would seek to hold countries and entities doing business with Tehran accountable, warning that those who refuse to cooperate with Washington could also face consequences.
The Treasury Department is expected to focus sanctions on several areas of Iran’s economy, including shipping, aviation, technology, gold and digital assets.
President Donald Trump has also been contacting foreign leaders in an effort to discourage economic and diplomatic engagement with Tehran.
The moves come as efforts to reopen the Strait of Hormuz remain stalled. The strategic waterway is crucial to global energy supplies, meaning any serious disruption could have consequences far beyond the Middle East.
For oil traders, the immediate question is whether the confrontation remains primarily economic or develops into another phase of military escalation.
Stephen Innes, global strategist at Quintex Intel, said the latest US strategy appeared designed to put severe financial pressure on Tehran while avoiding an immediate military escalation that could trigger a much larger shock in energy markets.
That distinction has helped prevent an even stronger surge in crude prices, although uncertainty surrounding the region continues to support oil.
Asian markets under pressure
Asian equities were less resilient on Tuesday, with technology companies bearing much of the selling pressure.
South Korea’s market fell sharply at one point, with major chipmakers SK hynix and Samsung among the companies weighing on the index. Hong Kong, Shanghai, Taipei and Manila also traded lower.
Japan, Australia, Singapore and New Zealand, however, recorded gains.
The uneven performance followed another difficult session for technology shares on Wall Street and reflected investor caution ahead of Nvidia’s earnings.
Nvidia has become one of the most closely watched companies in global markets because of its central role in the artificial intelligence boom. Investors have poured enormous amounts of money into AI-related companies and infrastructure, leaving markets increasingly sensitive to any indication that spending may not generate the returns expected.
The challenge for Nvidia is therefore becoming more demanding with every quarter.
A result that simply beats analysts’ estimates may no longer be sufficient if investors believe the company’s outlook does not justify its lofty expectations.
Nvidia earnings take centre stage
Investors will be watching Nvidia’s results closely for evidence of whether demand for AI chips remains strong enough to support the sector’s extraordinary growth.
Other technology companies, including Salesforce and Marvell, are also scheduled to report results, adding to what is already an important week for the sector.
Charu Chanana of Saxo Markets said investors were looking beyond the headline numbers and questioning whether Nvidia could deliver enough upside to support current valuations, particularly while bond yields remain high.
That concern reflects a broader problem for technology stocks: higher yields can make expensive growth companies less attractive because investors have alternatives offering higher returns from relatively safer assets.
Inflation remains a major concern
The oil market’s direction is also being watched closely by central bankers.
A sustained increase in crude prices could feed into transportation, manufacturing and consumer costs, making it more difficult for policymakers to bring inflation under control.
That concern comes as investors await the annual gathering of central bankers, economists and policymakers in Jackson Hole, Wyoming.
Federal Reserve Chair Kevin Warsh is expected to attract particular attention, with investors looking for signals about the direction of US monetary policy.
Markets are especially sensitive to those comments because inflation remains stubborn while borrowing costs are already elevated.
The US Treasury has also indicated that it plans to increase purchases of its own debt, a move aimed at easing pressure in parts of the bond market after the 30-year Treasury yield climbed to its highest level in nearly two decades.
Trade tensions add to uncertainty
Markets are also monitoring the worsening trade relationship between the United States and Canada.
The Canadian dollar edged higher on Tuesday after falling against the US dollar a day earlier, when Trump threatened to double tariffs on vehicles imported from Canada.
The threat followed the failure of US and Canadian officials to reach an agreement that would have prevented new 50 per cent US tariffs on certain Canadian goods.
Ottawa has already outlined retaliatory measures, raising the possibility of another major dispute between two closely connected economies.
With geopolitical tensions, trade disputes, inflation and technology valuations all competing for investors’ attention, markets are entering a particularly sensitive period.
For now, oil remains heavily influenced by developments involving Iran and the Strait of Hormuz, while equities are looking increasingly towards corporate earnings and interest-rate expectations.
The next major moves could depend on whether Washington’s economic campaign succeeds in containing the Iran crisis—or whether tensions eventually spill back into the energy market with much greater force.
