US stock markets fell Wednesday after President Donald Trump declared the ceasefire with Iran “over” during a NATO summit in Turkey. The announcement triggered a sharp surge in oil prices, with Brent crude jumping more than 5% to crest $80 a barrel, raising fears that renewed Middle East conflict could force the Federal Reserve to maintain higher interest rates.
Trump’s NATO Summit Remarks and the Ceasefire Collapse
The volatility in global markets followed President Donald Trump’s address at the NATO summit in Ankara, where he signaled a decisive end to recent diplomatic efforts. Trump criticized Iran’s leadership as “sick people” and expressed frustration regarding Tehran’s military alliance with Spain.
The President’s stance has left investors questioning the viability of any long-term peace.
“As far as I’m concerned, it’s over,” Trump said, though he noted that US negotiators had expressed a desire to continue talks.
While Trump suggested that the US-Israel offensive had effectively cut off Iran’s naval and air capabilities, the geopolitical landscape remains precarious. Israel’s leader, Benjamin Netanyahu, offered a more cautious assessment, stating the offensive was “not done yet” before initiating a new wave of strikes on Tehran on Tuesday.
Oil Surges as Middle East Tensions Escalate
Energy markets reacted violently to the news of potential renewed combat. Brent crude, the global benchmark, jumped more than 5% to crest $80 a barrel, while West Texas Intermediate (WTI) futures traded just below $72. The instability is compounded by a standstill in tanker traffic in the Strait of Hormuz, a critical waterway for global supply.
Analysts warn that the supply buffer is dangerously thin.
Any assumption of a swift return to normalized Persian Gulf exports is certainly being challenged. Given the reduced supply buffer of already low global reserves and inventories, any further escalations are likely to re-enforce a higher geopolitical risk premium in oil prices – even when negotiations eventually resume.

The impact is already being felt at the consumer level. US gas prices at the pump currently average $3.79 per gallon, which is $0.65 higher than a year ago.
Broadcom and Nvidia Drive Nasdaq Gains
Despite a massive selloff in industrial and materials sectors, the tech-heavy Nasdaq managed to avoid a steep decline, closing up 0.20% at 25,870.65 points. This resilience was largely fueled by a rally in semiconductor stocks.
Broadcom surged 4.8% following news that Apple plans to spend more than $30 billion as part of a chip-supply agreement. Additionally, Nvidia rose 3.65% amid reports that China may permit its top AI firms to purchase a limited number of the company’s H200 chips.
“Any time you get an announcement from Apple about using your equipment, it’s pretty positive — especially when you have 2.5 billion Apple devices in people’s hands around the globe,”

However, not all tech-adjacent names fared well. SpaceX fell 0.8% to $148.38, marking its lowest close since its Wall Street debut on June 12.
Federal Reserve Faces Pressure Amid Inflation Risks
The combination of rising energy costs and geopolitical instability has intensified the debate over interest rate policy. On Wednesday, the Dow Jones Industrial Average dropped 1.09% to 52,348.39 points, while the S&P 500 fell 0.28% to 7,482.71 points.
Recent minutes from the Federal Reserve’s June meeting reveal a central bank grappling with persistent price pressures. Officials noted both total and core inflation were higher than a year earlier, driven by higher energy costs from the Middle East conflict and demand from the AI buildout.
The economic outlook is being revised downward globally. The International Monetary Fund lowered its global economic growth forecast to 3%, down from 3.1% in April.
As traders look toward this week’s jobs report and upcoming inflation data, the primary concern remains the duration of the conflict.
Duration is the key here. How long does this go on? If we see damage to Iranian infrastructure, the market may have to respond more seriously to that because there’s likely Iranian retaliation.
