# Why Brent Crude Oil (BRENTOIL) rose 1.94% on October 20, 2026

Brent Crude Oil (BRENTOIL) rose 1.94% on October 20, 2026 — Brent tops $110 on Persian Gulf tanker attacks.

## What happened

Brent crude climbed 1.9% to top $110 a barrel as tanker attacks raised concerns about Persian Gulf supply. Brent reached a five-month high as attacks on ships and Saudi sites added to supply fears.

## Why it moved

Attacks on tankers directly threaten the flow of crude through the Gulf, which carries a large share of global seaborne oil.

## Why it matters

Hormuz and Gulf supply risk, together with tight refined-product markets, keeps crude bid across the cycle. Integrated producers such as Chevron capture the premium as prices stay elevated.

## What would break the thesis

If the attacks stop or naval escorts restore safe passage, Brent can give back the risk premium quickly. A sustained disruption that removes actual barrels from the market would push prices higher still.
