Brent crude oil dropped to $80.08 per barrel on June 16, marking the first time the global benchmark has traded below the $80 level since early March. The 3.71% single-day decline came on top of a 4.8% drop in the prior session.
The catalyst is straightforward: diplomatic negotiations between the US and Iran are raising expectations that the Strait of Hormuz, one of the most critical oil transit chokepoints on the planet, could see reduced tension and reopened supply flows.
From $100 to $80 in a matter of months
Earlier in 2026, Brent crude was trading above $100 per barrel. Geopolitical friction, particularly involving Iran and the threat of supply disruptions through the Strait of Hormuz, had pushed prices to those levels. A roughly 20% decline from those highs in a compressed timeframe reflects how quickly sentiment can flip when diplomacy enters the picture.
