Brent Crude Tops $100 as US-Iran Strikes Rattle Oil Markets

Today’s Focus

Brent crude, the global oil benchmark, climbed above $100 a barrel on Wednesday for the first time since late July, according to the BBC and The Guardian.

The Guardian reported Brent rose about 2.7% to roughly $100.60 before easing. The BBC noted it later slipped back to $99.90, with the door open to further gains if fighting intensifies.

The jump followed the latest round of strikes between Washington and Tehran. The US military said it destroyed five Iranian oil tankers on Tuesday, the BBC reported, retaliating after Iran tried to hit a US Navy warship with ballistic missiles.

Four of the tankers, struck in the Gulf of Oman, were linked to Iran’s Revolutionary Guard Corps (IRGC), with a fifth hit near Kharg Island. Tehran responded by firing missiles at a US base in Jordan, most of which were intercepted, and claimed attacks on two US vessels and eight tankers in the Strait of Hormuz.

The day before, Iran-backed Houthi forces struck four Saudi cities, wounding more than 70 people and setting oil installations ablaze, The Guardian reported.

The conflict began in late February when the US and Israel launched strikes on Iran. A ceasefire collapsed at the end of July, the BBC said, and fighting has escalated over the past week.

Energy prices in Europe rose too. The Guardian reported Dutch gas hit its highest level since January 2023.

The Debate

Supporters argue

Backers of the US strikes frame them as a proportionate response to direct attacks on American forces. The Pentagon said it acted only after Iran attempted to hit a Navy warship, casting the tanker strikes as self-defense rather than provocation.

Supporters contend that letting Iranian attacks go unanswered would invite more aggression against US ships and Gulf shipping lanes. Targeting IRGC-linked tankers, in this view, degrades the funding and logistics behind Tehran’s operations.

On sanctions, the Treasury Department has moved to tighten pressure, with the AP reporting new measures aimed at Iran’s aviation sector to further isolate the regime. Advocates argue sustained economic and military pressure is the only way to force Tehran back toward a durable ceasefire.

They also note that Saudi Arabia, a key US partner, is under direct Houthi fire, strengthening the case for a firm American posture in the region. For supporters, backing down would raise, not lower, the long-term risk to energy security.

Critics argue

Critics warn the tit-for-tat strikes are dragging the US deeper into an open-ended war with no clear exit. Each round of retaliation, they argue, raises the odds of a wider conflict that could choke off shipping through the Strait of Hormuz.

They point to the economic fallout as evidence the strategy is backfiring at home. With Brent above $100 and European gas at multi-year highs, opponents say American and allied consumers are absorbing the cost of escalation through higher fuel and heating bills.

Bank of England governor Andrew Bailey told MPs the oil spike is pressuring inflation and rates, warning “the risks, I’m afraid, are on the upside,” according to The Guardian.

Critics also question the humanitarian toll of the broader conflict, citing reports of civilian casualties in both Saudi Arabia and Yemen. They argue diplomacy, not further strikes, offers the only realistic path to stabilizing prices and ending six months of fighting.

What the experts say

Energy economists have long flagged the Strait of Hormuz as the world’s most critical oil chokepoint. The US Energy Information Administration (EIA) estimates that roughly 20% of global petroleum liquids consumption, about 20 million barrels a day, passes through the strait.

That concentration explains why localized fighting can move global prices so sharply. RAND Corporation analysts have noted that even the threat of disruption in Hormuz tends to add a risk premium to crude, regardless of whether physical supply is actually cut.

History offers a benchmark. During the 1980s “Tanker War” between Iran and Iraq, hundreds of vessels were attacked, yet the strait was never fully closed, in part because Iran also depends on it for its own exports.

On inflation, the International Monetary Fund (IMF) has estimated that a sustained 10% rise in oil prices can shave a few tenths of a percentage point off global growth while pushing up consumer prices. That link is why central bankers like Bailey are watching crude closely.
