• Brent crude prices have surged above $90 per barrel amid rising U.S.-Iran tensions.
• Only four vessels transited the Strait of Hormuz on Sunday, signaling disrupted oil shipments.

• Analysts warn that current oil market reactions may be complacent regarding potential inventory impacts.

Oil prices climbed sharply as the continued conflict between the United States and Iran intensified, pushing Brent crude to over $90 per barrel. Prices increased 3% on these tensions, reaching up to $90.79 by the end of trading, which extended a prior surge of 15.9% last week, marking the largest weekly gain since April, according to Reuters and India Times.

The ongoing conflict has raised concerns regarding crude supply disruptions in the Strait of Hormuz, a critical waterway that handles about one-fifth of global oil trade. Recent military actions have created a significant decline in shipping activity, with only four vessels reported traversing the strait on Sunday, compared to eight the previous day. Analysts indicate that this reduction will have major implications for oil supplies, particularly as the U.S. military enforces a naval blockade on Iranian ports while Iran targets vessels it deems as violators of its navigation rules, as shared by India Times and Los Angeles Times.

The U.S.'s military involvement escalated with airstrikes on Iran being conducted for the ninth consecutive night, following the unfortunate death of an American service member in Iraq. Iran has launched retaliatory attacks targeting U.S. allies in the region, such as Bahrain and Kuwait, raising alarms of a widening conflict. As military tensions grow, oil prices reflect these uncertainties, with concerns about global inventory levels intensifying. Barclays analyst Amarpreet Singh noted that the oil market appears to be complacent about potential fallout from these geopolitical events, according to Reuters and Los Angeles Times.

As shipping routes become increasingly volatile, the ramifications on oil exports and market stability deepen. A vessel reported a fire early Monday near Oman's coastline, further complicating transit. The U.S. military is urging vessels to reroute closer to Oman, although Iran's ongoing retaliatory actions pose significant risks to maritime movement. With these developments, analysts highlight the need for close monitoring of oil markets amidst these tensions, citing that current price levels are substantially below the 2026 peak of $126 a barrel seen earlier in the conflict, according to Reuters and Los Angeles Times.
