Crude oil benchmarks posted modest gains on Friday despite lingering concerns about the durability of a freshly brokered peace accord between Washington and Tehran, highlighting the fragile nature of geopolitical settlements and their outsized influence on global energy markets. The rally, however, came against a backdrop of significant weekly losses and reflected the tension between initial optimism over the agreement and emerging signs of its vulnerability, as key diplomatic engagements were postponed and regional hostilities continued to escalate.

Brent crude futures climbed 51 cents to settle at $80.36 per barrel, representing a 0.64% gain, while West Texas Intermediate crude rose more sharply by $1.28 to $77.88 per barrel, a 1.7% increase. The urgency was underscored by the expiration of the front-month WTI July contract on Monday, which added tactical buying pressure to the market. More actively traded August WTI futures advanced 59 cents to $76.44 per barrel. Yet despite Friday's recovery, both major benchmarks remained on track for weekly declines of approximately 8%, reflecting the broader uncertainty that has permeated trading desks across Asia and beyond.

The cancellation of planned talks between US and Iranian negotiators in Switzerland proved a critical turning point, with Vice President JD Vance abandoning his intended travel to the Swiss location. This withdrawal signalled potential fissures in the recently concluded interim understanding and raised questions about whether the agreement, signed just days earlier by both nations' leaders, possessed sufficient foundation to withstand the pressures of implementation. The postponement amplified doubts among traders who had begun to price in a more stable Middle East trajectory.

Analysts characterised the development as a warning sign that institutional support for the peace framework might be less solid than headline announcements suggested. Vandana Hari, founder of Vanda Insights, a specialised oil market analysis firm, observed that crude prices may have established a temporary floor but were vulnerable to renewed volatility as structural cracks appeared in the memorandum of understanding. She cautioned that the geopolitical environment offered little reassurance about normalised shipping through the Strait of Hormuz, one of the world's most critical energy corridors through which roughly a fifth of global oil and liquefied natural gas had flowed before hostilities intensified.

Israel's acceleration of military operations against Hezbollah in Lebanon presented perhaps the gravest risk to the credibility and longevity of the US-Iran pact. The continued escalation in Lebanese territory suggested that regional powers remained locked in confrontational postures despite the headline agreement, raising the prospect that the peace deal might prove insufficient to de-escalate underlying tensions. This dynamic created a ceiling on how much confidence oil traders could place in any supply normalisation thesis.

On Thursday, both crude benchmarks had touched their lowest levels since early March as vessels began transiting the Strait of Hormuz following the presidential accord. Three Saudi-flagged tankers carrying a combined 6 million barrels of crude navigated the strait hours after the deal was formalised, suggesting initial momentum toward renewed commerce. However, Friday's cautious moves indicated that traders remained unconvinced such movements would represent a sustained pattern rather than an isolated occurrence.

The strategic importance of restored Hormuz traffic cannot be overstated for the global energy system and Southeast Asian economies dependent on stable crude supplies. Industry analysts had projected that a successful agreement could unlock more than 85 million barrels of crude currently stranded in Middle Eastern Gulf storage facilities and injection into international markets. The lifting of US sanctions on Iranian oil sales would further expand available supply, potentially depressing prices if the political framework held firm. For Malaysian and regional energy-importing economies, such additions to global supply could provide welcome relief from price pressures, though the uncertain outlook complicated planning.

Tim Waterer, chief market analyst at KCM, articulated the market's wait-and-see posture, noting that traders sought concrete evidence of normalised tanker movements before committing to additional downside price moves. The psychological dimension of crude markets ensures that confidence in supply security often matters as much as actual barrel flows. Until shipping patterns demonstrably returned to pre-conflict norms, price discovery would remain anchored by caution.

Middle Eastern producers had begun mobilising to resume export operations. Kuwait Petroleum Corporation lifted all force majeure declarations issued during the conflict as of Thursday, signalling confidence in returning to full operational capacity. Iraq's oil minister Basim Mohammed announced that the nation's oilfields stood prepared to gradually restore production to previous levels. Such statements represented necessary preconditions for a genuine supply rebound, yet their credibility depended entirely on sustained political stability in the region.

The dichotomy between supply-side readiness and geopolitical fragility encapsulates the central challenge confronting crude markets. Infrastructure and operational capacity could be restored relatively quickly, but the political foundations required to sustain that restoration remained visibly fragile. Every cancelled diplomatic meeting and every escalating Israeli operation in Lebanon transmitted doubt back through the supply chain and into traders' calculations. Until the peace agreement demonstrated resilience through successive weeks and months of implementation, oil prices would likely remain range-bound and volatile, with each geopolitical tremor triggering sharp movements in either direction. For Malaysian importers and consumers, this uncertainty prolongs the period of pricing unpredictability.
