# Brent Crude Tops 90 Dollars as Iran Strikes Tankers and Hormuz Traffic Slows

Iran's Revolutionary Guard said two oil tankers were disabled while attempting a southern route through the strait, and traffic through the passage that carries the largest share of the world's seaborne oil has fallen sharply over the past three weeks.

Oil prices climbed for a second straight session on Monday as the conflict between the United States and Iran reached the shipping lanes of the Persian Gulf. Brent crude for September delivery rose more than 2 percent to trade above 90 dollars a barrel, and West Texas Intermediate advanced about 2.1 percent to near 83.5 dollars, according to [Globes](https://www.globes.co.il/news/article.aspx?did=1001549851#utm_source=RSS) and confirmed by [CNBC](https://www.cnbc.com/2026/07/20/oil-prices-today-brent-wti-crude-us-iran-centcom-hormuz.html).

The immediate cause was an attack on shipping. Iran's Islamic Revolutionary Guard Corps said two oil tankers exploded and were immobilized after they tried to transit what it called an unsafe southern corridor through the Strait of Hormuz, a claim carried by [The Hindu](https://www.thehindu.com/news/international/iran-israel-war-live-updates-july-20-2026-marco-rubio-strait-of-hormuz-us-donald-trump/article71243740.ece). The [Financial Times](https://www.ft.com/content/52e98fc4-32e3-4ed9-90fd-dcbba6188df5?syn-25a6b1a6=1) reported that the United States carried out a fresh wave of attacks as American casualties rose, while [Euronews](https://www.euronews.com/2026/07/20/iran-launches-retaliatory-attacks-after-us-completes-ninth-night-of-strikes) said the fighting had largely halted movement through the strait.

Roughly a fifth of the world's seaborne oil normally passes through Hormuz. Any sustained interruption forces buyers in Asia and Europe to compete for barrels shipped from elsewhere, and it raises revenue for producers outside the Gulf each time the risk premium widens.

The increase reverses an earlier decline that had taken crude back toward pre-war levels, and it reintroduces an energy-driven inflation impulse at a moment when central banks had been counting on cooling price pressure.

## What this means

A higher and more persistent oil price transmits directly into headline inflation for every net importer, which narrows the room central banks have to cut interest rates. Oil producers and integrated energy companies gain income, while import-dependent economies such as India, Japan and much of Europe face wider trade deficits and currency pressure. Airlines, chemicals and other fuel-intensive sectors lose margin. The channel is real prices moving faster than policy can respond.

## What to watch

- Whether tanker insurers keep raising war-risk premiums for Hormuz transits, which would raise landed crude costs even if no more ships are hit.
- Volumes of oil actually clearing the strait each day, because a genuine blockade rather than a scare is what turns a price spike into a supply shortage.
- Statements from Gulf producers on spare capacity and alternative pipeline routes, which would signal how much of any shortfall can be replaced.
