Brazil's oil output surges as 2026 Middle East war disrupts global supply

In early 2026 a direct military clash between the United States, Israel and Iran rendered the Strait of Hormuz impassable. The closure removed as much as 14 million barrels of crude per day from the market, pushing Brent crude above US$130 a barrel and triggering sharp increases in global food prices and shipping insurance.

The disruption forced oil‑importing nations to seek alternatives. Brazil, the United States and Guyana quickly expanded output. Brazil’s pre‑salt fields reached a historic 4.3 million barrels per day in May 2026, positioning the country as a key “last‑resort” supplier for European and Asian markets. The short‑term surge in Brazilian production helped stabilise prices but also highlighted the vulnerability of global energy supplies to geopolitical choke‑points such as Hormuz.
