Why is the Strait of Hormuz being described as 'effectively closed', and what are the immediate consequences for global energy markets?

The Strait of Hormuz has been 'virtually impassable since the conflict began in late February', cutting off flows of crude, gas, and oil products — a disruption that has 'upended global markets' and driven up energy prices. The International Energy Agency has labeled the war-induced shortage 'the biggest supply shock in history', underscoring its unprecedented impact on global energy supply and inflation risks.

What role is the U.S. naval blockade playing in the current Iran–U.S. negotiations, and how does it affect Iran's position?

President Donald Trump stated that Iran has asked the U.S. to lift 'a naval blockade of the strait while the two sides negotiate an end to hostilities', indicating the blockade is a central leverage point. Dennis Kissler of BOK Financial Securities Inc. assessed that 'the US still holds the much bigger advantage, and Iran is feeling the pressure of the blockade', confirming its strategic weight in compelling Iranian concessions.
