Oil edges higher as Israel-Lebanon fighting raises regional supply fears

Brent and WTI climb after Israeli advance in southern Lebanon; traders remain cautious over Strait of Hormuz flows

By Marcus Reed

Oil prices climbed in Asian trade as renewed combat between Israel and the Iran-backed Hezbollah in Lebanon heightened concerns about potential disruptions to Middle East oil supplies. Brent and WTI each gained 2.1% after steep weekly declines, while uncertainty around U.S.-Iran negotiations and shipping through the Strait of Hormuz kept traders on edge.

Oil edges higher as Israel-Lebanon fighting raises regional supply fears

Key Points

  • Brent and WTI futures both gained 2.1% in Asian trade, trading at $92.99 and $89.20 per barrel respectively - moves that followed recent steep weekly declines of roughly 10% for each contract.
  • An Israeli order to push deeper into southern Lebanon escalated fighting with Hezbollah, reviving fears the conflict could spread and threaten energy infrastructure or shipping routes.
  • Negotiations toward a more permanent U.S.-Iran truce appeared stalled, and uncertainty over approval from the U.S. president kept traders wary of potential disruptions through the Strait of Hormuz, which handles about one-fifth of global oil shipments.

Oil futures rose in Asian trading on Monday amid renewed clashes between Israel and the Iranian-backed Hezbollah group in Lebanon, reviving concerns over supply risks in the Middle East.

Price moves - As of 19:49 ET (23:49 GMT), Brent crude futures for August delivery were up 2.1% at $92.99 per barrel, while West Texas Intermediate (WTI) crude futures also gained 2.1% to trade at $89.20 per barrel.

The gains followed steep weekly declines for both contracts. Each contract fell roughly 10% over the prior week - their sharpest weekly drops in several weeks - after reports emerged that Washington and Tehran were discussing a possible ceasefire framework that could ease disruptions around the Strait of Hormuz.

Market momentum shifted over the weekend, however, when Israeli forces ordered troops to advance deeper into southern Lebanon. That move intensified Israel's campaign against Hezbollah despite earlier ceasefire efforts and raised the prospect that the fighting could widen across the region or endanger energy infrastructure and shipping lanes.

At the same time, talks toward a more permanent truce between the U.S. and Iran appeared to have stalled. Iranian officials indicated that significant issues remained unresolved, and reports noted any extension of a ceasefire agreement would still require approval from U.S. President Donald Trump. The lack of clarity around those negotiations contributed to trader caution.

Traders remain particularly watchful of flows through the Strait of Hormuz, a key maritime choke point that handles roughly a fifth of global oil shipments. Observers noted that, while prices had fallen on Friday amid reports of progress toward a U.S.-Iran understanding, shipping activity through Hormuz remained below normal levels and supply concerns had not been fully eliminated.

Oil markets have experienced sharp swings recently as participants reacted to a mix of military developments and diplomatic headlines. The combination of heightened regional military activity and uncertainty about diplomatic progress left market participants jittery about the prospect of further interruptions to oil flows.


Key context provided in this report:

  • Brent and WTI each rose 2.1% to $92.99 and $89.20 per barrel, respectively, as of 19:49 ET (23:49 GMT).
  • Both contracts had posted weekly drops of about 10% prior to Monday's gains, their largest weekly declines in several weeks.
  • Renewed military action in southern Lebanon and stalled U.S.-Iran truce talks contributed to elevated market uncertainty.

Risks

  • Escalation of the Israel-Lebanon conflict could further threaten energy infrastructure and shipping routes - impacting oil producers, refiners, and maritime shipping operators.
  • Stalled negotiations between the U.S. and Iran create uncertainty around any long-term ceasefire - posing downside or upside risk to oil supply stability and energy market forecasts.
  • Continued below-normal shipping activity through the Strait of Hormuz keeps the risk of supply interruptions elevated - affecting global oil logistics, tanker operators, and downstream fuel markets.
