Why Brent Crude Oil (BRENTOIL) rose 1.94%
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.
