The war involving Iran remains front and center as financial markets head into a week shortened by a U.S. holiday. Fighting that has expanded across the Middle East shows no sign of abating even as U.S. President Donald Trump has signaled that direct talks with Tehran may be making headway. At the same time, the conflict continues to push oil prices far above where they were before hostilities began, adding another layer of uncertainty as the January-to-March quarter draws to a close on Tuesday.
1. Conflict widens in month two
Combat operations continued into a second month with reports of projectiles fired by Iran at Israel and other locations in the Persian Gulf. The scope of hostilities has broadened; Iran-aligned Houthi forces in Yemen have launched strikes that, according to Israeli military statements, included drone attacks intercepted en route to Israel. Analysts and market participants have flagged growing concerns about disruptions to crude shipments, particularly while the Strait of Hormuz remains effectively closed.
Reports in the press have said the White House is weighing a complex military plan to remove almost 1,000 pounds of uranium from Iran. U.S. military movements have also intensified: troops from the U.S. 31st Marine Expeditionary Unit are reported to have arrived in the Middle East, a deployment described as a way to increase Washington's operational choices as leaders evaluate next steps. A separate report noted Pentagon preparations for weeks of ground operations in Iran, while Tehran has publicly warned it would destroy any U.S. forces attempting a ground incursion.
Casualties and injuries from the broader campaign have already been reported: at least 12 U.S. troops were injured in an Iranian strike on an air base in Saudi Arabia over a weekend. The entrance of Houthi forces into the campaign has raised particular apprehension about additional maritime choke points. Analysts at Vital Knowledge warned that if Houthi operations target the Bab al-Mandab Strait - a critical passage connecting the Red Sea to the Gulf of Aden and the Indian Ocean - an existing global shipping crisis created by the effective closure of the Strait of Hormuz would be "dramatically amplif[ied]."
2. Diplomatic language and mixed signals from Washington
President Trump told reporters aboard Air Force One that negotiations with Iran were proceeding "extremely well" and suggested that a deal with Tehran could be near. "I think we’ll make a deal with them, but it’s possible we won’t," he said, adding in response to a follow-up question: "I do see a deal with Iran, could be soon."
Those remarks followed reports of potential U.S. plans that could complicate diplomatic openings, including the aforementioned idea of extracting uranium from Iran. In comments to the Financial Times, the president also said he wants to take Iran's oil and discussed the possibility of seizing Kharg Island, a major export hub for Tehran, telling the newspaper: "Maybe we take Kharg Island, maybe we don’t. We have a lot of options."
Iranian officials have largely denied that direct discussions with Washington have taken place since the start of hostilities and have insisted that a halt to fighting is a precondition for any negotiations.
3. Oil prices remain elevated
With Middle East supplies constrained, Brent crude futures have climbed sharply - rising from roughly $70 a barrel before the conflict began in late February to more than $107 a barrel on Monday. Market watchers and analysts are publicly discussing how interruptions to oil shipments could ripple through other parts of the global economy.
Higher diesel costs, for example, could push food prices up, while fertilizer supplies - which often depend on natural gas inputs and ties to Middle East production hubs - have become scarcer and more expensive for farmers. Industrial inputs are also feeling strain: helium, a key component in the manufacture of semiconductors used across artificial intelligence applications, is reported to be in short supply. Aluminum, widely used in autos and aircraft, has experienced similar constraints.
Those supply squeezes have helped stoke broader inflation worries. The conflict has prompted forecasts for elevated global inflation that could, in turn, trigger further cycles of interest rate increases by central banks. Bond yields worldwide have moved higher, exerting additional stress on equity markets.
Yet not all market strategists believe the fallout is being fully priced in. Thomas Mathews, Head of Markets, Asia Pacific, at Capital Economics, told clients that markets do not seem to be "too concerned, yet, about fiscal and inflation risks." He added that "[t]he war's effects on markets may continue to elude an easy solve."
4. Quarter-end and a turbulent first three months
The Iran conflict is only one of several forces investors have contended with during a volatile first quarter. The January-to-March period, which ends on Tuesday, also featured actions and events that unsettled markets and elevated geopolitical risk concerns.
Among the other headline developments through the quarter were a presidential threat to take over Greenland - a semiautonomous territory belonging to Denmark, a NATO ally - and a dramatic U.S. attack on Venezuela that resulted in the capture of that country's longtime leader, Nicolas Maduro, an event traders spent time analyzing for its wide-ranging consequences for oil and Latin American stability.
Domestically, anxiety over artificial intelligence intensified as new tools and entrants into the sector accelerated technological change. Rapid product updates from new firms, including Anthropic, fed concerns about the pace of disruption. Software-as-a-service firms came under particular stress as market participants debated whether AI-driven advances would reduce demand for established services such as legal advice and data analysis. Some corporations, citing AI among the reasons, have moved to reduce headcount; Block Inc. is named among companies that linked AI to mass layoffs.
The prospect that AI-driven shifts could destabilize credit dynamics has also surfaced. Warnings have been issued about higher default rates in direct lending, pointing to vulnerability in private credit markets that were once considered robust.
5. Economic calendar and the labor market focus
Investors will also be parsing a set of U.S. economic releases this week that could illuminate how the conflict is translating into domestic economic performance. On Wednesday, the Institute for Supply Management's manufacturing gauge for March is scheduled to be published. Wall Street forecasts predict the index will fall but remain in expansionary territory.
Friday brings the closely watched U.S. jobs report for March. Current economist expectations are for the economy to have added 56,000 positions in the month, a rebound from a decline of 92,000 jobs in February. The unemployment rate is projected to remain at 4.4%.
Market participants and policymakers alike may treat the nonfarm payrolls numbers as a key input when assessing monetary policy options. Analysts at ING noted that the labor-market data will be pivotal: "In terms of the U.S. data this week, the focus will be on the labor market," they wrote, adding that Friday's NFP release "should leave the market minded to price [Fed] tightening this year in response to the energy shock. Any surprise weakness could hit the dollar."
Looking ahead
As the first quarter closes, investors must weigh both geopolitical developments and domestic data points in calibrating risk. The ongoing hostilities in and around Iran have introduced material questions about energy supply chains, shipping lanes and commodity inputs that intersect directly with inflation, industrial production and financial conditions. At the same time, the coming week’s economic readings - particularly the ISM manufacturing index and the March jobs report - stand to influence expectations for central bank responses, potentially affecting interest rates, yields and equity valuations.
For market observers, the combination of a widening regional conflict, elevated crude benchmarks and a critical batch of U.S. data makes for a concentrated period in which shifts in sentiment and policy expectations could be swift and consequential.
