Market Snapshot Global financial markets came under pressure after attacks on oil tankers in the Persian Gulf and renewed warnings from Iran raised fears of a deeper energy supply crisis. The escalation briefly pushed Brent crude above US$100 per barrel , marking one of the sharpest moves in oil prices since the conflict began.

Market Snapshot
The ongoing conflict involving Iran, the United States and Israel is causing severe disruption to maritime traffic through the Strait of Hormuz, one of the most critical shipping routes for global energy supply.
In recent days, tanker movements through the strait have nearly stopped, as Iranian forces warned commercial vessels that ships could face missile or drone attacks. The dramatic drop in shipping activity has already triggered sharp increases in oil and gas prices, raising concerns about the risk of global inflation shocks.
Energy markets are closely monitoring developments as Western governments explore measures such as naval escorts for tankers, although implementation may take time.
Why the Strait of Hormuz Is So Important
The Strait of Hormuz is one of the most strategically significant energy corridors in the world.
Located between Iran to the north and Oman and the United Arab Emirates to the south, the narrow waterway connects the Persian Gulf to the Indian Ocean.
Key facts about the strait:
Nearly 25% of global seaborne oil trade passes through Hormuz
About 20% of global LNG supply moves through the route
Shipping lanes in each direction are only two miles wide
Major oil exporters that rely on the strait include:
Saudi Arabia
Iraq
Iran
Kuwait
Qatar
United Arab Emirates
Bahrain
Most of these energy exports are shipped to Asian economies, making the region particularly sensitive to any disruption.
Oil Prices React to Supply Risks
Energy markets have already responded to the disruption.
With tanker traffic collapsing and some Gulf producers reducing output due to storage constraints, crude prices have surged.
The supply shock is compounded by the fact that global spare export routes are extremely limited, meaning that even a temporary disruption could tighten global supply quickly.
Higher oil prices typically feed directly into transportation costs, electricity prices and broader inflation.
LNG, Metals and Food Supply Also at Risk
The Strait of Hormuz is not only critical for oil shipments.
The waterway also plays a major role in transporting:
Liquefied natural gas (LNG) — especially from Qatar
Aluminum exports
Agricultural commodities such as fertilizer and sugar
Around one-fifth of global LNG supply passed through Hormuz last year.
Disruption could therefore push up global natural gas prices, especially in energy-importing Asian economies.
The conflict also comes at a sensitive time for agricultural markets, as farmers in the Northern Hemisphere begin applying fertilizers for the upcoming planting season.
Can Iran Block the Strait Completely?
While Iran has previously threatened to close the Strait of Hormuz, a full blockade is unlikely due to the strong military presence of Western naval forces in the region.
However, Iran does not need to fully close the waterway to create disruption.
Potential tactics include:
Harassing ships with fast patrol boats
Missile or drone attacks on tankers
Deploying naval mines
Jamming GPS signals used for navigation
Maritime intelligence data suggests more than 1,000 vessels in the Persian Gulf have experienced GPS signal interference during the current conflict.
Even limited disruption can significantly affect shipping because commercial vessels are reluctant to enter high-risk zones.
Can the US Restore Safe Shipping?
The United States is exploring measures to stabilise shipping flows.
Proposals include:
Naval escorts for commercial tankers
Political risk insurance for vessels
The US International Development Finance Corporation has proposed a maritime insurance programme covering up to US$20 billion in losses.
However, insurance coverage alone may not convince shipping companies to return if the risk of attack remains high.
Limited Alternatives for Oil Exporters
Several Gulf countries have few or no alternatives to bypass the Strait of Hormuz.
Countries with no alternative shipping route include:
Kuwait
Qatar
Bahrain
Some producers have partial alternatives:
Saudi Arabia
Uses the East-West pipeline to ship oil to the Red Sea port of Yanbu
Maximum capacity: 7 million barrels per day
United Arab Emirates
Uses the Habshan–Fujairah pipeline
Capacity: 1.5 million barrels per day
However, these alternatives cannot fully replace Hormuz traffic.
Even these routes face risks, as Houthi militants in Yemen have threatened to attack vessels in the Red Sea.
Investor Takeaways
The Strait of Hormuz handles roughly one-quarter of global seaborne oil trade, making it a critical energy chokepoint.
Shipping traffic has nearly collapsed due to the Iran conflict, pushing oil prices higher.
Disruption could trigger higher global inflation through rising energy and shipping costs.
Asian economies are particularly exposed, as they receive most oil and LNG shipped through Hormuz.
Markets will closely watch whether naval escorts or diplomatic efforts restore shipping flows.
