# Brent oil price in May posts biggest monthly loss since 2020

> Brent fell just over 19% in May, its worst monthly performance since March 2020, while WTI dropped nearly 17%. Traders bet on a US-Iran agreement that would reopen the Strait of Hormuz. President Trump laid out demands that Iran has previously rejected, including no nuclear weapon and removal of mines and tolls.

## Why it matters

The monthly decline reflects expectations that Hormuz flows will resume, which lowers energy costs across feed supply chains. Uncertainty over the deal leaves room for a sharp rebound if talks fail.
