Brent crude has slid below $80 per barrel for the first time since early March, driven by growing confidence that a US-Iran ceasefire extension will reopen the Strait of Hormuz to normal shipping traffic. The benchmark has dropped more than 4% in recent days, marking one of the steepest monthly declines since 2020.

The deal driving the drop

The US and Iran have agreed to extend their ceasefire for 60 days, building on an initial pause that was brokered by Pakistan and first announced on April 8. A formal signing is expected around June 19 in Switzerland, with US President Donald Trump and Iranian Deputy Foreign Minister Kazem Gharibabadi among the key figures involved in negotiations.

The Strait of Hormuz is the world’s most important oil chokepoint. Roughly a fifth of the global petroleum supply passes through the narrow waterway between Iran and Oman on any given day. The strait’s closure in recent months had already depleted global oil inventories and squeezed regional exports. With traders now pricing in a resumption of normal flows, the supply picture has shifted dramatically. US WTI crude has also tumbled below $80, reflecting a decrease of roughly $10 per barrel in the previous week as ceasefire progress accelerated.

Why crypto investors should care about crude oil

Bitcoin mining is an energy-intensive operation. When crude oil falls, it tends to pull down the broader energy complex, including natural gas and electricity prices in many regions. Lower input costs mean higher margins for miners, which reduces selling pressure on mined Bitcoin.

Oil is a major input cost across the global economy, from transportation to manufacturing to food production. A sustained decline in crude prices eases inflationary pressure, which in turn gives central banks more room to hold rates steady or even cut.

Geopolitical risk hasn’t disappeared

The ceasefire has been extended multiple times since April. If the agreement collapses, oil prices could snap back violently. Brent was trading well above current levels when the strait was effectively closed, and a return to those conditions would reverse every benefit outlined above.

Investors watching this space should pay attention to the June 19 signing date in Switzerland. If the deal gets formalized, the current price move in crude likely has legs. If talks stall or break down, the reversal could be sharp.
