Oil Heads for 8% Weekly Loss as Tanker Blockage Clears

Crude oil prices slumped on Friday and were on track to close the week down nearly 8%, as supply fears that had flared over the weekend evaporated. Several tankers that had been stranded in the Strait of Malacca – a key chokepoint for global oil flows – started moving again, a sign that the disruption was short-lived.

The blockage had created a temporary premium in oil futures, especially in refined products linked to Asian refineries that rely on the strait. As the logjam broke, that premium unwound. The weekly loss is the steepest in more than a month, wiping out gains built on supply disruption speculation.

For traders, the move underscores how quickly geopolitical or logistical risk premiums can dissipate when the disruption is resolved before it affects actual cargo schedules. The next leg for oil will depend on whether other supply-side catalysts – such as OPEC+ output plans or US inventory draws – re-emerge as the headline risk fades.

The retreat leaves Brent and WTI testing levels that prevailed before the tanker incident, with the market effectively repricing the probability of a broader supply squeeze. Whether that repricing holds will hinge on the next tangible data point, not further speculation about the strait's vulnerability.
