Why Maersk Raised Guidance Twice This Year: A Strait of Hormuz Case Study in Volatility

An unusual kind of good news

On Aug. 13, 2026, Danish shipping giant A.P. Moller-Maersk raised its full-year 2026 earnings guidance for the second time this year:

• Underlying EBITDA guidance: $10.5-12.5 billion, up from the $8-10 billion range set in late June, which itself had been raised from an original $4.5-7 billion.
• Free cash flow guidance: improved from "at least -$1.5 billion" to "greater than $0."
• Second-quarter revenue: up 20% year-over-year to $15.8 billion.
• Net profit: more than doubled to $1.31 billion, from $639 million a year earlier.

Shares jumped on the news; the size of the move was reported anywhere from roughly 5% to 8%, depending on the source and the exact timing measured.

That's a striking earnings beat for a shipping company navigating what Maersk itself describes as an active geopolitical crisis. The explanation: the same disruption driving up Maersk's costs is also driving up what its customers pay to ship goods.

The Strait of Hormuz chokepoint behind the numbers

The Strait of Hormuz — the narrow waterway between Iran and Oman through which roughly a fifth of the world's oil normally transits — has been a flashpoint since a U.S.-Israel military campaign against Iran began Feb. 28, 2026. Iran's Revolutionary Guard declared the strait closed days later and warned it would target non-compliant vessels; multiple tanker attacks followed. A ceasefire on April 8 briefly eased tensions, but Iran's Revolutionary Guard resumed blocking traffic within days, and the disruption continued through the month. By late April, the International Maritime Organization was reporting roughly 20,000 stranded mariners and 2,000 ships backed up in the Persian Gulf.

In June, the U.S. and Iran signed an agreement establishing a temporary safe-passage arrangement. But as of Maersk's Aug. 13 earnings report, Iran disputes U.S. claims that the strait has fully reopened, and vessel-traffic data shows daily transits still running roughly 90% below the pre-war average — near multi-month lows. In practical terms, that means shippers are still routing around the region or paying steeply elevated costs to move through it, five and a half months into the disruption.

How the chokepoint shows up in Maersk's earnings

Maersk's results illustrate both sides of that tradeoff.

Cost side: Average bunker (ship fuel) prices rose 44% year-over-year, and rerouting around the affected region adds distance, time and expense to affected trade lanes.

Revenue side: Maersk's average loaded freight rate rose 22% year-over-year, as reduced shipping capacity through the normal routes pushed up what all shippers charge. Industry-wide, the Drewry World Container Index — a widely tracked benchmark of global container shipping rates — stood at $4,339 per 40-foot container in mid-August, up roughly 119% from its late-February, pre-crisis level, though the increase varies significantly by trade lane.

Maersk also disclosed a roughly 40% contraction in Middle East import volumes, partly offset by continued strength in Chinese exports.

Maersk isn't alone. Rival Hapag-Lloyd also raised its 2026 outlook on the same theme, while separately disclosing roughly $600 million in additional Hormuz-related costs this year, spanning bunker fuel, insurance, rerouting and inland transportation.

Why this is a useful case study, not a stock tip

The lesson for options-education purposes isn't "buy shipping stocks" or "the Strait of Hormuz crisis is good for Maersk." It's that a single, ongoing geopolitical event can push a company's costs and revenue in the same direction at the same time — and the net effect on earnings can still surprise even close observers. (Maersk has now revised its own full-year guidance twice, each time significantly higher than the last.) That kind of outcome uncertainty is exactly what shows up as elevated implied volatility in a stock's options: the market prices in a wider range of plausible outcomes precisely because the situation is genuinely unresolved, not because anyone has better information about which way it breaks.

For a trader thinking about sector volatility rather than a single-stock directional bet, this is also a reminder that options strategies exist specifically to express a view on uncertainty itself — not just on price direction. Strategies that profit from elevated volatility carry their own risk if that volatility collapses faster than expected — for example, if the strait dispute resolves cleanly. Strategies that bet against volatility, on the other hand, can produce outsized losses if a geopolitical situation like this one escalates further rather than resolving. Either way, position sizing and risk limits matter more, not less, when the underlying uncertainty is this event-driven and headline-sensitive.

Options trading involves substantial risk and is not suitable for all investors.
