Oil Prices Jump Above $107 as Trump Rejects Iran's Strait of Hormuz Reopening Proposal

Global oil markets reacted sharply on Monday after United States President Donald Trump dismissed an Iranian proposal that would have seen the Strait of Hormuz reopened within a week, sending crude prices climbing more than 3 percent during Asian trading hours.

Brent crude, the international benchmark for oil pricing, approached $108 a barrel before easing somewhat later in the day. By late morning in London, November futures for Brent were changing hands at $107.35 a barrel, reflecting sustained uncertainty about the future of one of the world's most critical energy chokepoints.

The market movement followed Trump's weekend announcement that Tehran's latest offer to bring an end to the ongoing US-Israel war on Iran was unacceptable. The proposal, which Iran unveiled at the United Nations General Assembly on Friday, had outlined a series of reciprocal measures aimed at de-escalating the conflict.

Under the terms of Iran's plan, Washington would have released frozen Iranian financial assets, lifted economic sanctions, and terminated its naval blockade of Iranian ports. In return, Tehran would have reopened the Strait of Hormuz and returned to the negotiating table to discuss its nuclear programme, all within a seven-day timeframe. Trump's rejection of the deal means those measures will not proceed, leaving the waterway's status unresolved and markets on edge.

The Strait of Hormuz holds immense strategic significance for global energy supplies. Before the US and Israel launched military strikes on Iran in late February, roughly one-fifth of the world's oil supplies passed through the narrow waterway, which connects the Gulf to the Gulf of Oman and the Arabian Sea. Any disruption to traffic there reverberates across energy markets worldwide, affecting everything from fuel prices to inflation expectations.

Shipping activity in the strait has fallen dramatically since the war began, with numerous attacks on commercial vessels in the Gulf region. Most of those incidents have been attributed to Iran or groups aligned with it. The decline in traffic has tightened supply conditions and contributed to the volatility that has characterised oil markets in recent months.

According to maritime intelligence platform MarineTraffic, vessels completed 132 transits of the strait between September 21 and 27, up from 116 the previous week. While that represents a modest improvement, it remains a fraction of normal levels. Before the conflict started, the waterway typically saw approximately 130 crossings every single day, underscoring how far traffic has fallen.

The ripple effects of the oil price surge were visible across Asia Pacific equity markets, which posted a mixed session. Wall Street had ended the previous week on a positive note, with the benchmark S&P 500 gaining 0.5 percent on Friday, but Asian investors appeared more cautious as they assessed the implications of the failed diplomatic opening.

Japan's Nikkei 225 index dropped 0.73 percent, while South Korea's Kospi fared worse, falling 2.70 percent. South Korea is particularly sensitive to energy price movements given its heavy reliance on imported crude for its industrial economy. Hong Kong's Hang Seng Index managed a gain of 0.54 percent, and Australia's S&P/ASX 200 edged up 0.17 percent, suggesting that the sell-off was not uniform across the region.

The rejection of Iran's proposal marks another setback in efforts to wind down a conflict that has already reshaped energy flows and heightened geopolitical tensions. Trump's decision signals that Washington is seeking more far-reaching concessions from Tehran before agreeing to any easing of pressure, particularly regarding Iran's nuclear ambitions and its role in regional security.

For Iran, the failed initiative leaves its economy under continued strain from sanctions and the naval blockade, while its leadership must weigh whether to offer further concessions or adopt a more confrontational posture. The coming weeks will be closely watched for signals about whether either side is willing to revive negotiations or whether the standoff will deepen further.

Oil traders are likely to remain focused on developments surrounding the Strait of Hormuz, as any sign of renewed hostilities or further restrictions on shipping could push prices even higher. Conversely, any diplomatic breakthrough would probably trigger a rapid price correction. Uncertainty about the duration of current supply disruptions is expected to keep markets volatile in the near term.

The broader global economy also faces risks from sustained high energy costs. Elevated oil prices feed through to transportation, manufacturing, and consumer goods, complicating efforts by central banks to manage inflation. Asian economies that depend heavily on Middle Eastern crude imports are especially vulnerable to prolonged disruption.

With the diplomatic window appearing to close, the Strait of Hormuz remains both a vital economic artery and a flashpoint in the wider US-Iran confrontation. How the standoff evolves will shape not only energy markets but also the geopolitical landscape of the Middle East for months to come.
