Oil prices experienced a slight decline on Tuesday following a significant surge the day before, prompted by US President Donald Trump’s assertion that he had facilitated a cessation of Israeli military operations in Lebanon. Brent crude fell by 0.6% to $94.45 per barrel, retracting some of the gains made on Monday, while West Texas Intermediate (WTI) hovered around $90.60 during Asian trading hours.
Market Fluctuations Following Political Claims
The recent fluctuations in oil prices can be traced back to a tumultuous Monday, which saw Brent crude rise by 4.2%, closing at $94.98 per barrel, marking its highest performance since early May. WTI also enjoyed a robust 5.5% increase, finishing at $92.16, its most significant daily gain since late April. The initial surge was largely attributed to reports from Iran’s semi-official Tasnim news agency, which indicated that Tehran had suspended indirect negotiations with the US in response to Israeli actions in Lebanon.
The situation intensified as reports emerged that Iran, alongside its allies in Yemen, Lebanon, and Iraq, aimed to completely obstruct critical shipping routes such as the Strait of Hormuz and the Bab el-Mandeb Strait—key channels through which around 20% of global oil and gas supplies transit. Furthermore, an Axios report highlighted Iran’s deployment of additional naval mines in the Strait, fuelling concerns over a potential prolonged disruption.
Trump’s Diplomacy and Market Reactions
However, the market retraced some of its gains on Tuesday after President Trump claimed he had not been informed about Iran’s decision to halt discussions. He asserted that negotiations were ongoing “at a rapid pace,” following conversations with Israeli Prime Minister Benjamin Netanyahu and Hezbollah representatives. Trump declared that both parties had reached an agreement to cease hostilities, stating on Truth Social, “There will be no troops going to Beirut,” and adding that Hezbollah had consented to halt all fire.

In a separate statement, Netanyahu communicated to Trump that Israel would target locations in Beirut if Hezbollah did not cease its attacks on Israeli cities, maintaining that Israeli military operations would continue as planned in southern Lebanon. Meanwhile, Lebanon’s presidency announced that discussions would persist throughout the week to extend a US-brokered ceasefire across the entire nation, beyond just southern Lebanon.
In an interview with ABC News, Trump mentioned the possibility of finalising a memorandum of understanding with Iran to reopen the Strait within a week, although he acknowledged that “a few more points” needed to be settled.
Cautious Optimism Amidst Uncertainty
Despite Trump’s optimistic outlook, analysts voiced scepticism regarding the likelihood of a successful resolution. Fabien Yip, a market analyst at IG in Sydney, noted the frequent false starts in ceasefire negotiations since April. “The market has become accustomed to the back-and-forth,” Yip remarked, indicating that current progress may not signify a lasting breakthrough.
Asian stock markets also reflected this uncertainty, with the MSCI’s index of Asia-Pacific shares outside Japan dipping 0.6%. The Nikkei 225 index in Japan fell by 1.9%, while South Korea’s KOSPI experienced significant volatility, dropping as much as 3.3% before regaining some ground. South Korea’s consumer price inflation reached a two-year high in May, raising expectations for a potential interest rate hike by the Bank of Korea in its upcoming meeting.
In the US, the S&P 500 closed up 0.3% after manufacturing activity in May reached its highest level in four years, likely driven by businesses anticipating rising prices and supply shortages due to the ongoing conflicts in the region. This marked the index’s ninth consecutive week of gains.
Why it Matters
The dynamics surrounding oil prices are intricately linked to geopolitical developments. As tensions in the Middle East continue to shape market sentiments, any sign of diplomatic progress—or lack thereof—could dramatically influence global oil supply and pricing, affecting economies worldwide. The interplay between political decisions and market reactions underscores the delicate balance that policymakers must navigate, with the potential for significant economic repercussions riding on the outcome of these negotiations.
