What will a US Naval Blockade of Iran Mean for Oil Flows?

The U.S. Military began blocking shipping traffic in and out Iran's port. This would prevent approximately two million barrels per day of Iranian oil from reaching the global?markets.

Here's a look at the details of the "blockade" and its impact on oil markets.

WHAT HAS BEEN ANNOUNCED?

After the weekend talks between the U.S., Iran and other negotiators in Islamabad ended without agreement, President Donald Trump announced that the U.S. Navy would "begin the process of BLOCKADADING any and ALL ships trying to enter or leave the Strait of Hormuz."

U.S. Central Command announced on Monday that vessels not authorised to enter or leave the blockaded area would be subjected to "interception, divertison, and capture". The U.S. Central Command said that it would not interfere with the freedom of navigation by vessels transiting through the Strait of Hormuz from or to non-Iranian port.

Iran's Revolutionary Guards warned Trump that any military vessel approaching the Strait would be treated as a breach of ceasefire and punished harshly.

What is the impact on oil flows?

Blocking Iranian oil shipments would remove a major source of oil from world markets. Iran exported 1.84 million barrels of crude oil per day in March, and has shipped 1,71 million barrels of crude so far in April. This compares to an average of 1.68 millions bpd by 2025.

Kpler data revealed that a spike in Iranian production before the start of the war on February 28 had led to a near-record level of Iranian oil being loaded onto?ships. As of early this month, more than 180,000,000 barrels were either in transit or in floating storage. Kpler data showed that more than 180 million barrels of Iranian oil were in transit or floating storage as early as this month.

OIL FLOWS from other Gulf producers?

The shipping traffic through the Strait of Hormuz has been largely stopped despite the two-week ceasefire announced by Washington and Tehran on April 7.

Two more vessels crossed the strait with the Chinese tanker on Tuesday. It was the first time a tanker has passed through the strait since the U.S. blockedade.

Two Pakistani flagged tankers, Shalamar, and Khairpur entered the Gulf on Sunday to load cargoes coming from the United Arab Emirates (UAE) and Kuwait. A third Liberian flagged ship, Mombasa B was also transiting the strait and ballasting in Gulf.

The Malta-flagged VLCC Agios Fanourios I turned back after trying to pass through the Strait of Hormuz on Sunday in order to load Iraqi crude oil bound for Vietnam.

Kpler reports that as of April 7th, 187 tankers containing 172 millions barrels of crude and refined oil were in the Gulf.

Which importers are most affected?

Prior to the war, China was the largest crude oil importer in the world. The U.S. announced a waiver of sanctions last?month that has allowed other buyers to import Iranian crude oil, including India.

Ship tracking data from LSEG & Kpler revealed that India is?set to receive India's first crude shipment from Iran since seven years this coming week.

Before the war, around 20% of the world's oil and gas exports went through the Strait of Hormuz. Most of the cargoes were headed for Asia, which is the biggest importing region.
