Oil falls as supply flows through Strait of Hormuz after US-Iran peace deal

The August Brent contract fell 30 cents to $75.55 per barrel on June 19, as multiple Saudi-flagged supertankers carrying a combined 6 million barrels of crude sailed through the strait just hours after a US-Iran memorandum of understanding was announced. That price represents a sharp retreat from the $100-plus levels Brent hit during months of military tensions that had effectively shut down shipping access since early March.

What the deal actually does

The MOU, signed around June 17, grants toll-free passage for oil tankers through the strait for an initial 60-day window. It also opens the door for further negotiations on Iran’s nuclear program.

Within hours of the announcement, Saudi Arabia had supertankers moving through the strait. Six million barrels is not a trivial amount of crude.

From $100 to $75 in a matter of weeks

When the strait was effectively blockaded starting in early March, Brent surged past $100 per barrel. A drop from above $100 to $75.55 represents a decline of roughly 25% from the conflict highs.

The 60-day toll-free window is long enough for markets to normalize shipping routes and rebuild inventory levels that were depleted during the blockade. But it’s also short enough that traders will start pricing in uncertainty again as the deadline approaches, unless the broader negotiations produce something more permanent.

The crypto angle no one expected

Before the peace deal materialized, Iran had been exploring the use of Bitcoin and stablecoins as potential payment mechanisms for maritime shipping tolls as early as April 2026. The US responded by sanctioning crypto wallets linked to the effort, targeting approximately $344 million worth of digital assets.

Bitcoin itself rallied to nearly $67,000 in the wake of the MOU announcement.

The Iran crypto-toll experiment appears to be shelved for now, given the toll-free terms of the current agreement. The sanctioning of $344 million in crypto wallets shows that US authorities are more than willing to use the full weight of their enforcement apparatus when digital assets intersect with national security concerns.
