Iran-US Conflict Escalates: Oil Prices Surge and Global Markets React

The U.S. and Israel have launched military strikes against Iran, intensifying a conflict that has led to a de facto closure of the Strait of Hormuz. Iran has responded by issuing threats against ships transiting the critical energy corridor. The situation has triggered widespread concern about energy security and global economic stability.

Brent crude oil prices have surged past $114 per barrel amid fears of prolonged disruptions to oil and liquefied natural gas (LNG) shipments. The Strait of Hormuz handles roughly 20.9 million barrels per day, making it a crucial bottleneck for global energy markets. A 24-hour drop in shipping activity was observed following the escalation.

Asian economies, which import 40-80% of their crude oil through the strait, are particularly vulnerable. Low pipeline bypass capacity and minimal strategic petroleum reserves have limited their ability to absorb supply shocks. India, which sources 50% of its crude oil through the strait, could see its GDP growth impacted by up to 0.15 percentage points.

Why Did This Happen

The Strait of Hormuz closure has highlighted the strategic importance of the waterway as a global energy chokepoint. With a 21-mile passage, the strait is narrow and heavily relied upon by international markets. A single incident can cause a sharp drop in shipping activity and ripple across energy markets.

Iran's threats against shipping and the U.S.-Israeli military actions have created a volatile environment. Analysts warn that the duration of the conflict is a key factor in determining the scale of economic damage. Prolonged conflict could drive oil prices to $120–$150 per barrel.

How Markets Responded

Global equity markets have reacted with sell-offs, particularly in Asian markets. The U.S. Treasury yields have risen as investors reprice inflation risks linked to higher energy prices. The 10-year Treasury yield increased by 20 basis points following the conflict.

The housing market has also been affected. Mortgage affordability has been undermined as energy prices and Treasury yields surged. Analysts note that the conflict has reversed recent gains in mortgage affordability and raised concerns about the spring housing season.

Central banks, including the Federal Reserve, are now more cautious about rate decisions. JPMorgan estimates that the energy shock could reduce global growth by 0.6 percentage points in the first half of the year. The Fed may now consider smaller rate cuts or pauses as inflationary pressures increase.

What Are Analysts Watching

Investors are closely monitoring the duration of the conflict. A short-term escalation may limit economic damage, but a prolonged conflict could lead to sustained oil price spikes and higher inflation. Morgan Stanley advises investors to consider themes such as defense, security, aerospace, and industrial resilience.

The impact on India is another focus. With limited alternatives to the Strait of Hormuz, India faces a potential rise in its fiscal deficit and economic slowdown. Analysts are watching whether global oil prices can stabilize or if further price spikes will emerge.

The housing market is also under scrutiny. Analysts are assessing whether the conflict will have a material impact on construction and freight costs. While short-term volatility is expected, some believe housing demand could remain resilient if the conflict does not escalate further.
