Brent crude tops $100 as Iran–US tensions and Hormuz strike claims rattle oil security
Brent crude has climbed back above $100 a barrel amid rising Iran–US tensions and Iranian claims of missile strikes near the Strait of Hormuz, just as US emergency oil stocks fall to their lowest level since 1982.
Brent crude pushed back above $100 a barrel on 9 September as tensions between Iran and the United States raised fresh doubts over the security of Gulf energy routes.
Benchmark Brent prices hit $100 a barrel for the first time since July 24, with traders reacting to both geopolitical risk and signs of thinner safety buffers on the supply side.
Iran’s Islamic Revolutionary Guard Corps said it had launched ballistic missile strikes against US military positions, including the Al Azraq airbase in Jordan, and targeted what it called vessels trying to enter a “prohibited and unsafe” area of the Strait of Hormuz. The IRGC claimed that two US vessels, eight oil tankers and 10 other vessels were among those targeted. These claims have not been independently verified.
Unconfirmed reports also circulated of an Iranian drone strike on an oil tanker docked off the coast of Dubai in the United Arab Emirates. With no official confirmation, that remains an allegation, but it adds to a sense of heightened risk for ships in the Gulf and Gulf of Oman.
At the same time, US Strategic Petroleum Reserve stocks have fallen to their lowest level since 1982. The reserve is Washington’s main emergency crude buffer, and lower volumes there leave less room to respond quickly if a serious supply disruption hits global markets.
Commentary from US observers added another layer of concern, noting that the United States burned through more than two months’ worth of Patriot PAC‑3 interceptor missiles during what they described as a massive Iranian ballistic missile attack. Those figures were not officially confirmed, but they fed worries that defensive stockpiles, like oil reserves, are being drawn down faster than they can be rebuilt.
For import‑dependent economies and consumers, triple‑digit oil means higher fuel costs feeding into transport and inflation. For tanker operators and charterers, any credible threat to vessels near Hormuz forces decisions on routes, insurance and crew safety even without a declared closure of the waterway.
Key signals now are whether US and regional officials confirm any of the claimed strikes, how long Brent stays above $100, and whether Washington hints at changes to naval deployments, sanctions policy or refilling the Strategic Petroleum Reserve.
