The Strait of Hormuz: A Global Energy Chokepoint
Hoxton Blog • The Strait of Hormuz: A Global Energy Chokepoint
Recent events in the Middle East have pushed energy markets and geopolitical risk back into the headlines.
Whenever tensions rise in this region, investors inevitably begin asking the same question: What does this mean for markets and for my portfolio?
The answer in this case centres on a single, strategically important location. Much of the market reaction we have seen in recent days is not simply about the conflict itself, but about the risk that it could disrupt one of the world’s most important energy routes: the Strait of Hormuz.
Understanding why that narrow shipping corridor matters helps explain the recent move in oil prices, the market volatility we have seen, and why long-term investors should approach developments in the region with perspective rather than panic.
What is the Strait of Hormuz?
The Strait of Hormuz sits between Iran and Oman at the entrance to the Persian Gulf.
At its narrowest point, it measures just 34 kilometres across, yet it carries a remarkable share of global energy supply. Every day, around 20 million barrels of oil pass through the strait, representing roughly 20% of the world’s daily production.
It is also the main transit route for liquefied natural gas exports from Qatar, one of the largest LNG suppliers globally.
Because so much energy supply depends on this single corridor, even the possibility of disruption can move markets.
Since the recent escalation in the region, Iran’s Revolutionary Guard has declared the strait effectively closed to vessels linked to the U.S., Israel, and their allies.
Several shipping companies have paused routes through the region, and more than 150 tankers are currently waiting outside the strait.
In response, the International Energy Agency has authorised the release of 400 million barrels from global strategic reserves to help offset potential supply disruption.
Key Strait of Hormuz Facts

| Daily oil flow | ~20 million barrels |
| Share of global oil supply | ~20% |
| Share of global LNG trade | ~20–30% |
| Vessels currently waiting | 150+ |
| Strategic reserves authorised | 400 million barrels |

| Saudi Arabia | 38% | 7.6 million |
| UAE | 22% | 4.4 million |
| Iraq | 21% | 4.2 million |
| Kuwait | 10% | 2.0 million |

| Others | 4% | 0.8 million |

There are also mechanisms that help cushion supply shocks.
Saudi Arabia has already redirected some exports through its Red Sea pipeline network to the port of Yanbu. The U.S. Navy has begun escorting commercial vessels through the region.
These measures cannot fully replace the capacity of the Strait of Hormuz overnight. However, they do reduce the likelihood of a prolonged supply disruption.
What Has Happened to Oil Prices?
Energy markets reacted quickly as the risk to shipping through the Strait of Hormuz became clearer.
Brent crude began the year at roughly $61 per barrel, reflecting a global supply surplus. Following the escalation of the conflict, prices rose sharply.
They briefly touched the high $80s per barrel before easing slightly as strategic reserves were released and early diplomatic signals began to emerge.
US crude oil followed a similar pattern.
This chart illustrates how quickly energy markets respond when supply risks appear.
Brent and WTI Oil Price Movement
| Date | Brent | WTI | Key Event |
|---|---|---|---|
| January 2026 | $61 | $57 | Year opens |
| February 1 | $63 | $59 | Rising tensions |
| February 28 | $68 | $64 | Military strikes |
| March 1 | $74 | $70 | Market reaction |
| March 3 | $85–88 | $79–83 | Hormuz closure |
| March 5 | $82 | $76 | Strategic reserves released |
| March 11 | $84 | $78 | Prices stabilise |

Higher oil prices tend to feed through into everyday costs.
Fuel prices rise. Transport becomes more expensive. Airline tickets increase. Goods that rely on shipping or manufacturing become more costly.
The IMF estimates that every 10% rise in oil prices can add roughly 0.4% to global inflation and reduce economic growth by about 0.15%.
These are meaningful numbers. However, they assume a sustained disruption to energy supply. At the moment, most analysts consider a prolonged closure of the Strait of Hormuz unlikely.
It is also worth remembering that higher energy prices can benefit energy companies and commodity-linked investments. If your portfolio includes exposure to these sectors, they may be acting as a natural hedge during periods like this.
What Is Happening in the Conflict
On February 28, 2026, the U.S. and Israel carried out coordinated strikes on Iran, targeting parts of its nuclear programme and ballistic missile infrastructure.
The attacks reportedly killed Iran’s Supreme Leader and caused significant damage to military facilities.
Iran has since responded with missile and drone strikes against Israeli targets, US military bases across the Gulf region, and vessels near the Strait of Hormuz.
The conflict has now entered its second week.
Diplomatic efforts are underway. Regional powers, including Qatar, have called for de-escalation, and there are early reports of back-channel communications.
For markets, however, the key issue remains the same.
The stability of the Strait of Hormuz.
Markets Have Seen Events Like This Before
Periods of geopolitical tension can create sharp market reactions.
History shows, however, that markets have repeatedly recovered once uncertainty begins to fade.
We saw similar patterns during the Gulf War in 1991, the Iraq conflict in 2003, the pandemic shock in 2020, and the brief Iran-Israel exchange in 2025.
Investors who remained invested during those periods generally experienced far better long-term outcomes than those who moved to cash.
The long-term data tells a consistent story. Markets experience shocks, but over time they continue to grow.
Stay Calm. Stay Invested.
Periods of volatility often create a strong urge to act.
Moving to cash can feel like the cautious choice. Waiting until markets settle may appear sensible.
Historical data tells a different story.
The strongest market gains often occur during or immediately after periods of uncertainty. Investors who step aside risk missing those recovery days.
Missing just a small number of the market’s best days can have a significant impact on long-term returns.
The Cost of Missing the Market’s Best Days
| Investor Behaviour | Portfolio Value | Difference |
|---|---|---|
| Stayed fully invested | $380,000 | Baseline |
| Missed best 10 days | $195,000 | −49% |
| Missed best 20 days | $118,000 | −69% |
| Missed best 30 days | $76,000 | −80% |
Illustrative example based on historical S&P 500 return patterns. $10,000 invested over 20 years. Past performance is not a reliable indicator of future results.
A diversified portfolio is not designed to avoid all downturns.
Its purpose is to ensure that no single event, region, or sector can derail your long-term financial plan.
Diversification Through Market Cycles
| Crisis | Diversified Portfolio | Single Asset Class | Difference |
|---|---|---|---|
| 2001 Tech crash | -12% | -28% | +16% |
| 2008 Financial crisis | -22% | -38% | +16% |
| 2020 COVID shock | -15% | -24% | +9% |
| 2022 Rate shock | -14% | -22% | +8% |
Average recovery time:
- Diversified portfolio: 8 months
- Single asset class: 17 months
Past performance is not a reliable indicator of future results.
What We Are Watching
Over the coming weeks, we are closely monitoring several developments:
-
Shipping activity through the Strait of Hormuz
-
Diplomatic negotiations involving Qatar, Oman, and European mediators
-
The response of Saudi Arabia and other Gulf energy producers
-
Central bank reactions to higher energy prices
-
The resilience of global equity and credit markets
So far, financial markets outside the energy sector have remained relatively stable.
That resilience is encouraging.
Final Thought
Geopolitical events create noise. Your financial plan was designed to withstand it.
The investors who build the most wealth over time are rarely those who predict every crisis. They are the ones who remain disciplined, stay diversified, and stay invested when uncertainty is highest.
