Oil Prices Surge 5% as Trump Declares Iran Ceasefire 'Over', Global Stock Markets Tumble

Global financial markets were rocked on Wednesday after U.S. President Donald Trump declared that the ceasefire with Iran was effectively "over," reigniting fears of a broader conflict in the Middle East.

The renewed tensions sent oil prices soaring by more than 5% while major stock markets across Europe, Asia, and the United States recorded sharp losses as investors rushed toward safer assets.

The latest escalation follows renewed attacks on commercial vessels in the Strait of Hormuz, one of the world's most important oil shipping routes. The United States responded with extensive military strikes on Iranian targets earlier this week after the attacks, prompting fresh retaliation against American military bases in the Gulf.

Speaking during the NATO summit in Turkey, Trump said the ceasefire had collapsed but indicated that diplomatic negotiations could still resume.

Brent Crude Climbs Above $77 as Oil Supply Fears Intensify

The worsening security situation immediately impacted global energy markets.

International benchmark Brent North Sea Crude climbed more than 5% to $77.93 per barrel, while West Texas Intermediate (WTI) surged 5% to $73.95 per barrel, as traders priced in the growing risk of disruptions to global oil supplies.

Adding to market uncertainty, Washington revoked a temporary sanctions waiver that had allowed limited Iranian oil exports, further tightening global supply expectations.

Kathleen Brooks, Research Director at XTB, noted that geopolitical risks are once again dominating investor sentiment.

According to Brooks, Brent crude could rise above $80 per barrel if tensions escalate further, particularly if the United States imposes a naval blockade in the Strait of Hormuz that prevents Iran from exporting crude oil.

Global Stock Markets Slide as Investors Dump Risk Assets

The spike in oil prices triggered widespread selling across global equity markets.

European markets traded sharply lower:

- FTSE 100 (London): -1.4%

- CAC 40 (Paris): -2.0%

- DAX (Frankfurt): -2.1%

Asian markets also suffered significant losses.

South Korea's Kospi Index plunged 5.4%, extending losses after reaching record highs only weeks ago. Japan's Nikkei 225 dropped 2.1%, while China's Shanghai Composite slipped 0.5%.

Hong Kong was the lone bright spot, with the Hang Seng Index jumping 3% as bargain hunters snapped up beaten-down technology stocks.

Samsung, SK Hynix Extend Tech Sell-Off

Technology stocks remained under heavy pressure as investors continued to question whether the massive spending on artificial intelligence can be sustained.

Despite forecasting a nearly 19-fold increase in second-quarter operating profit, Samsung Electronics fell around 6%, extending Tuesday's heavy losses.

Chipmaker SK Hynix also dropped roughly 6% as investors continued to take profits following months of AI-driven gains.

Market analysts say concerns over stretched valuations and excessive investment in AI infrastructure are prompting investors to rotate away from technology stocks.

Dollar Strengthens as Inflation Concerns Return

The U.S. dollar gained against major global currencies as rising oil prices renewed fears that inflation could remain higher for longer.

Higher energy prices could complicate the Federal Reserve's monetary policy, potentially delaying interest rate cuts or even forcing policymakers to maintain tighter financial conditions for longer than previously expected.

Outlook

With military tensions escalating in the Middle East and uncertainty surrounding global oil supplies, investors are preparing for increased market volatility in the coming weeks.

Analysts warn that any further disruption to shipping through the Strait of Hormuz or additional military action involving the United States and Iran could drive oil prices even higher, deepen stock market losses, and intensify inflationary pressures across the global economy.
