Quick Answer<\/strong><\/p>\n

The crude oil price today on 18 August 2026 moved higher as hopes for a lasting US-Iran peace deal faded significantly, with Iran announcing it will adopt a fully offensive military posture and Washington ruling out extending the temporary ceasefire. Brent crude futures rose 0.3% to $91.14 per barrel, their highest level since July 30, while WTI gained 0.3% to $85.04 per barrel. This move is being driven entirely by the geopolitical risk premium that returns whenever Strait of Hormuz supply routes face credible threats.<\/p>\n<\/div>\n

Global energy markets on 18 August reflect a sharp recalibration of geopolitical risk in energy markets. Brent crude futures climbed 27 cents, or 0.3%, to $91.14 per barrel in early Asian trading on 18 August 2026, the highest level since July 30. US West Texas Intermediate crude futures were up 42 cents to $85.04 per barrel, at their highest since July 31. Earlier in the session WTI had risen as high as $85.37, indicating that buyers are aggressive in pricing in the deteriorating Iran-US situation. This is therefore not a demand story but a supply-risk story.<\/p>\n

The catalyst is clear. Iran has informed major powers that it will shift to a fully offensive military posture because efforts to negotiate a permanent end to its conflict with the US and Israel have stalled, a senior Iranian official confirmed to Reuters on Monday. Washington simultaneously ruled out extending the temporary ceasefire agreement that had briefly allowed diplomatic discussions to take place. With the ceasefire window closed and Iran taking a harder military line, the path to a peace-related resumption of oil tanker traffic through the Strait of Hormuz is now significantly less clear. This is why Brent and WTI have risen to multi-week highs despite no physical supply disruption having occurred yet.<\/p>\n
