WASHINGTON — On Thursday morning, Brent crude oil prices surged past $125 per barrel amid growing uncertainty surrounding U.S.-Iran negotiations, casting doubt on the reopening of the Strait of Hormuz and the possibility of permanently ending the ongoing war in Iran.

In the commodities market, Brent crude for June delivery saw a significant increase of 6.2%, reaching $125.36 per barrel, while the July delivery also experienced a rise, climbing 3.1% to $113.85.

Meanwhile, the benchmark U.S. crude experienced a 2.3% hike, reaching $109.38 per barrel.

At the outset of the conflict in late February, Brent crude was approximately $70 per barrel, showcasing the impact of the prolonged hostilities. Now in its ninth week, the war in Iran shows no signs of abating. The United States continues to enforce a blockade on Iranian ports, and the closure of the Strait of Hormuz has contributed to the climbing oil prices. Recent reports on Thursday suggested that U.S. President Donald Trump might be considering an escalation, further diminishing hopes for a swift resolution to the conflict.

The Iran war, which is in its ninth week, still sees no clear path to an end. The U.S. has continued its blockade of Iranian ports while the Strait of Hormuz is closed, pushing oil prices higher. Reports Thursday suggesting a possible escalation by U.S. President Donald Trump doused hopes for a quick end to the conflict.

“The breakdown of talks between the U.S. and Iran, along with President Trump reportedly rejecting Iran’s proposal for a reopening of the Strait of Hormuz, has the market losing hope for any quick resumption in oil flows,” ING Bank strategists Warren Patterson and Ewa Manthey wrote in a research note.

Oil prices vary depending on the type of crude oil, where it is being traded and under what terms, for futures contracts. By some measures, Brent has hit its highest level since its peak of $147.50 per barrel in 2008 during the global financial crisis.

With the war rattling world markets, the U.S. dollar surged to 160.51 Japanese yen, its highest level in nearly two years. It closed at 160.44 yen on Wednesday.

The dollar has gained against other major currencies partly due to its status as a haven for investors in times of risk, and partly because U.S. interest rates have remained relatively high as the Federal Reserve strives to balance a need to boost the economy with the higher prices that are partly a result of the war.

The Fed’s decision to keep interest rates steady at its policymaking meeting Wednesday further supported the dollar.

Japanese officials would be likely to intervene in the market if the yen drops much more, analysts said.

The euro fell to $1.1663 from $1.1675.

U.S. futures and share prices in Asia retreated following a muted performance on Wall Street on Wednesday.

Tokyo’s Nikkei 225 shed 1.6% to 58,967.07 and the Kospi in South Korea fell 1.1% to 6,615.51.

China’s factory activity for April slowed slightly but remained in expansion territory for the second month, despite the global energy shock prompted by the Iran war, an official survey showed.

Australia’s S&P/ASX 200 was down 0.3% to 8,665.50.

Taiwan’s Taiex edged 0.1% lower while India’s Sensex lost 1.2%.

On Wednesday, U.S. stocks were mixed. The benchmark S&P 500 edged down less than 0.1% to 24,673.24. The Dow Jones Industrial Average fell 0.6% to 48,861.81, while the Nasdaq composite edged less than 0.1% higher to 24,673.24.
