Will Iran close Strait of Hormuz?

THREATS OF CLOSURE- TIMELINE Iran has only made noise so far about closing the Strait, but has never shut it down.

- 

US strikes on Iran's three main nuclear facilities have once again raised concerns that Tehran might shut down the Strait of Hormuz - one of the world’s most critical chokepoints, through which a fifth of global oil and gas supply flows.

Glimpse:

Geography: The Strait of Hormuz connects the Persian Gulf to the Arabian Sea and the Indian Ocean. The narrow channel, approximately 21 miles (33 kilometres) wide at the narrowest point, separates Iran (north) from the Arabian Peninsula (south). But shipping lanes in the waterway are even narrower - two miles wide in each direction, making them vulnerable to attacks and threats of being shut down.

Lifeblood of global oil & gas: The Strait of Hormuz is of great strategic and economic importance, especially as oil tankers collecting from various ports on the Persian Gulf must pass through the strait. It serves as the maritime artery through which a fifth of the world's oil and gas flows.

The bulk of oil exports from regional powerhouses - Saudi Arabia, Iraq, UAE, Qatar, Iran, and Kuwait - must transit this narrow waterway. India imports about 90 per cent of its crude oil, with over 40 per cent of those imports originating from Middle Eastern countries whose exports transit the Strait of Hormuz.

Is closure possible?
