Oil prices experienced a slight decline on Tuesday after a significant surge the previous day, following US President Donald Trump’s announcement that he had facilitated a cessation of Israeli military operations in Lebanon. Brent crude fell by 0.6 per cent to $94.45 per barrel, reversing some of the gains made on Monday. Meanwhile, West Texas Intermediate (WTI) hovered around $90.60 per barrel during Asian trading.
Market Reaction to Trump’s Claims
On Monday, oil prices had surged more than 5 per cent, driven by escalating tensions in the Middle East. The spike was initially prompted by reports from Iran’s semi-official Tasnim news agency, which indicated that Tehran had suspended indirect negotiations with Washington in response to Israeli actions in Lebanon. On that day, Brent crude finished at $94.98 per barrel, marking a 4.2 per cent increase—the largest since early May. WTI also experienced a significant jump of 5.5 per cent, closing at $92.16 per barrel.
The situation intensified as reports emerged that Iran and its allies had plans to obstruct key shipping routes, including the Strait of Hormuz and the Bab el-Mandeb Strait, crucial channels for global oil transport. Concerns grew following allegations that Iran had deployed additional naval mines in the Strait, signalling a potential prolonged disruption in oil supplies.
However, Trump’s comments on Tuesday reversed some of the market’s optimism. He asserted that he had not been informed of any suspension of talks by Iran and claimed that negotiations were proceeding “at a rapid pace.” Trump stated he had spoken with both Israeli Prime Minister Benjamin Netanyahu and representatives of Hezbollah, asserting that both parties had agreed to cease hostilities. In a post on Truth Social, he declared, “There will be no troops going to Beirut,” and indicated that Hezbollah had consented to halt all firing.
Mixed Signals from the Region
Despite Trump’s optimistic assertions, Netanyahu provided a more cautious perspective, stating that Israel would continue its military operations in southern Lebanon if Hezbollah did not cease its attacks. Lebanon’s presidency announced that negotiations would persist throughout the week to expand the US-brokered ceasefire beyond southern Lebanon to encompass the entire nation.

In an interview with ABC News, Trump speculated that a memorandum of understanding with Iran regarding the reopening of the Strait could be reached within a week. However, he acknowledged that a few points still required resolution.
Analysts Remain Skeptical
Market analysts expressed doubt regarding the sustainability of the ceasefire talks. Fabien Yip, a market analyst at IG in Sydney, noted that the negotiations have been riddled with false starts since April, suggesting that the market has become accustomed to the ongoing back-and-forth. “Today’s lack of progress is no exception,” he remarked, echoing concerns about the credibility of the current diplomatic efforts.
As oil prices fluctuated, broader Asian stock markets showed a downward trend. The MSCI index for Asia-Pacific shares outside Japan fell by 0.6 per cent, with Japan’s Nikkei 225 dropping 1.9 per cent. South Korea’s KOSPI index saw significant volatility, swinging up to 3.3 per cent lower before recovering slightly. This fluctuation coincided with new data indicating that South Korea’s consumer price inflation reached a two-year high in May, raising expectations for an interest rate hike from the Bank of Korea.
On the other side of the Pacific, the S&P 500 on Wall Street finished the day 0.3 per cent higher, buoyed by strong manufacturing activity which hit a four-year high in May. This increase is believed to be linked to companies rushing to place orders amid fears of rising prices and supply shortages stemming from the ongoing conflict.
Why it Matters
The fluctuation in oil prices is not merely a reflection of market speculation; it has profound implications for global economies and consumers alike. The geopolitical tensions in the Middle East, particularly involving key players like Iran and Israel, can significantly impact oil supply and prices, which in turn affect everything from fuel costs to inflation rates. As negotiations continue to evolve, the world watches closely, understanding that stability in this region is crucial for economic predictability across various sectors. The ongoing situation underscores the interconnectedness of global markets and the potential repercussions of diplomatic developments.
