US Iran Hormuz Blockade – Oil Above $100 & Peace Talks Collapse (April 2026)
Oil reportedly surpassed $100/barrel after US-Iran peace talks failed and the US announced a blockade of Iranian ports in the Strait of Hormuz. The UK declined to join the blockade while maintaining regional naval presence, and downstream effects include aviation fuel shortages, food security concerns, and global growth forecast cuts.

## Overview
Oil prices reportedly rose above $100 per barrel after the United States announced a blockade of Iranian ports following the failure of weekend peace negotiations (BBC, April 2026). The development deepened concerns about a worsening global energy crisis.
## Peace Talks Collapse
Negotiations that were reportedly underway through the weekend failed without agreement, triggering the US blockade announcement (BBC, April 2026). The failure followed earlier rounds of talks, including the US-Iran Islamabad Peace Talks which had also collapsed (existing wiki pages). Russia reportedly offered mediation after the nuclear talks collapsed.
