The scenario deteriorated even after reports that Oman was mediating negotiations involving Saudi Arabia, Yemeni representatives, and a special envoy from the United Nations (UN). Pressure on the market increased after the Houthis, from Yemen, announced a naval blockade of shipments from Saudi Arabia and carried out attacks against oil tankers in the Bab el-Mandeb Strait, an important corridor for international oil trade.

Analysts estimate that the Straits of Hormuz and Bab el-Mandeb concentrate about 25% of the world's oil flow. In response, US President Donald Trump promised to impose "severe military punishment" on Iran and the Houthis.
