There is a stretch of water just 33 kilometres wide at its narrowest point. Through it passes one-fifth of all the oil consumed on Earth every single day. Right now, that waterway — the Strait of Hormuz — is at the centre of the most consequential geopolitical crisis of 2026.
Understanding the Strait
The Strait of Hormuz connects the Persian Gulf to the Gulf of Oman and the Arabian Sea. On one side is Iran. On the other is Oman and the UAE. Every oil tanker leaving Saudi Arabia, Kuwait, Iraq, UAE, and Qatar must pass through this 33-kilometre bottleneck.
Approximately 21 million barrels of oil pass through the Strait every day. That is 20% of global oil consumption. There is no realistic alternative route for most of this oil.
What Iran Has Done
Iran has deployed anti-ship missile batteries along its coastline overlooking the Strait. Iranian naval vessels have been shadowing commercial tankers. Three tankers have already turned back rather than risk passage.
Iran’s Revolutionary Guard has issued direct warnings to shipping companies — pass at your own risk.
The US Response
The US Navy’s Fifth Fleet, based in Bahrain, has significantly increased its presence. American forces have been conducting strikes on Iranian missile positions. But destroying fixed missile batteries is straightforward — the problem is Iran’s mobile missile systems, which can be repositioned within hours.
The UAE has temporarily closed its airspace. Major airlines including Emirates, Air India, and IndiGo have been rerouting flights, adding hours and fuel costs to every journey.
The Economic Numbers
Every week the Strait remains disrupted, the global economy loses an estimated $30-50 billion. Oil at $105 per barrel is already causing inflation to re-accelerate in every major economy.
For India specifically — fuel prices, fertiliser costs, and freight rates all rise with oil. The rupee weakens as India’s import bill expands. The RBI faces a nightmare scenario of inflation rising while growth slows.
The Historical Precedent
This is not the first time Iran has threatened the Strait. During the Tanker War of the 1980s, Iran attacked 190 ships over three years. The US eventually escorted tankers through with naval protection. That operation, called Earnest Will, eventually succeeded — but it took 14 months.
The world is less patient now. Global supply chains are tighter. The economic consequences of a prolonged closure would be far more severe than in 1987.
What India Should Do
India’s strategic interest is clear — keep the Strait open. India has quietly been in contact with both the US and Iran. India’s relationship with Iran, built over decades of pragmatic engagement, may give New Delhi a diplomatic channel that Washington does not have.
India imports approximately 10% of its oil from Iran, despite US sanctions. That relationship is now a potential diplomatic asset.
