Oil Prices Above $100 as Iran-US Conflict Fuels Supply Fears


    By Dalal Street Investment Journal (DSIJ)

    Summary :


    Brent crude has moved above $100 per barrel as escalating Iran-US tensions and tanker attacks raise concerns over global oil supplies. The disruption around key shipping routes, including the Strait of Hormuz, has increased worries about inflation and market volatility.

    Oil Prices Cross $100 as Iran-US Conflict Raises Supply Concerns

    Oil markets had their most dramatic session in months on September 10, 2026. Brent crude surged past $106 a barrel, while WTI crossed the $100 mark for the first time since May. Neither move came out of nowhere; the market had been watching the Iran-US situation deteriorate for weeks, and a fresh wave of shipping attacks finally pushed prices over the edge.

    What Actually Happened?

    The trigger was a significant escalation in tanker attacks near the Strait of Hormuz. Iran reported strikes on ten vessels after the US targeted five Iranian oil tankers. That back-and-forth was enough to unsettle traders who had been hoping for some kind of ceasefire. Those hopes are now largely gone. Since early August, Brent has climbed more than 40%, a move that tells you just how quickly sentiment shifted once the conflict resumed.

    The pressure did not stop at the Gulf. Iran-aligned Houthis seized Yemen's port of Mocha, pulling Red Sea shipping routes into the picture as well. Two of the world's most critical energy corridors are now under simultaneous stress, and the market is pricing that in.

    Supply Numbers Are Not Helping Either

    Geopolitics alone rarely sustains an oil rally; supply fundamentals need to cooperate, and right now they are. OPEC trimmed its global demand growth forecast for 2026 to 380,000 barrels per day, the fifth straight downward revision. Meanwhile, actual OPEC output fell by 640,000 barrels per day in August, with disruptions hitting several major producers at once.

    China is the wildcard here. After a stretch of softer buying, the world's largest crude importer has returned to the market with renewed appetite. If that continues while supply routes stay under pressure, the rally has room to run further.

    Why Does This Hit India Harder Than Most?

    India imports 85-88% of its crude requirements, which means every dollar added to the barrel price lands directly on the current account. Airlines, logistics companies and industries running on petroleum-based inputs are already watching their cost structures carefully. A sustained move above $100 will eventually find its way into transport costs and consumer prices, giving the Reserve Bank of India one more uncomfortable variable to manage.

    Conclusion

    If the Strait of Hormuz remains contested and Houthi activity continues in the Red Sea, supply disruptions could deepen before they ease. On the other hand, diplomatic channels are rarely completely shut, and any credible signal of de-escalation would likely take some of the risk premium out of prices quickly.

    For now, the market is not betting on resolution. It is watching shipping data, inventory draws and OPEC's next move and sitting with the uncomfortable reality that two of the world's busiest oil corridors are in play at the same time.
