The closure of the critical oil corridor Strait of Hormuz will lead to a steep increase in oil prices affecting all countries as prices tend to be linked across markets

As the regional conflict in West Asia escalated with the US striking Iran, there are likely to be severe consequences on oil prices, the global economy and investment strategies around the world. On June 21, the US made airstrikes on three of Iran’s nuclear facilities: Fordow, Natanz, and Isfahan, which flared up geo-political tensions in the region.
In retaliation, Iran may close the critical oil corridor Strait of Hormuz (SoH), which remains one of the key energy choke points, through which almost 20 percent of global oil and liquified natural gas (LNG) are traded. SoH is the only marine entryway into the Persian Gulf, with Iran on one side and Oman and the UAE on the other. It also links the Persian Gulf to the Gulf of Oman and the Arabian Sea in the Indian Ocean.
Any escalation in the geopolitical situation could significantly impact global energy supplies and prices. The closure of this critical oil corridor will lead to a steep increase in oil prices affecting all countries even if it is not imported from the Gulf region as prices tend to be linked across markets.
According to Mark Haefele, chief investment officer, Global Wealth Management, UBS, there are two key questions: First, will energy exports including oil shipments from the Middle East be interrupted? Second, will other major countries intervene?
“Oil is the main conduit for the transmission of Middle East tensions to the global economy and broader financial markets, and in the very short term, oil prices are likely to rise as investors price the risk that the conflict escalates further and supplies are disrupted,” he adds.
