Strait of Hormuz Tanker Attack Drives European Gas Prices to Highest Level Since March
Key Points
- European natural gas contracts climbed more than 3.4% on Monday, reaching levels not seen since late March
- An attack on a commercial vessel resulted in a fire in the strategically vital Strait of Hormuz
- Approximately 20% of worldwide LNG volumes transit through this critical waterway
- Oil prices gained 2.2%, contributing to upward momentum in oil-indexed gas agreements
- War-risk insurance costs surged dramatically, directly impacting European gas valuations
European natural gas markets experienced significant upward pressure on Monday following a security incident in the Strait of Hormuz that has intensified concerns about the reliability of global LNG supply chains.
The Dutch TTF front-month contract, which serves as the continental benchmark, gained 3.45% during morning trading. Meanwhile, the UK’s wholesale gas contract for near-term delivery increased 3.52%. Both instruments touched their highest valuations since late March.

Security Incident Spurs Market Volatility
The rally in gas prices followed news that a commercial vessel was struck and caught fire while transiting the Strait of Hormuz. This narrow waterway represents one of the world’s most critical chokepoints for energy commodity transportation.
Roughly 20% of global liquefied natural gas shipments navigate through the Strait of Hormuz annually. The majority of these cargoes originate from major producers in the Persian Gulf region. Any potential disruption to this route immediately captures the attention of European energy traders.
In recent years, Europe has dramatically increased its dependence on waterborne LNG imports. This shift accelerated after Russian pipeline deliveries collapsed in the wake of the Ukraine conflict. Today, imported LNG represents a critical component of the continent’s energy security, powering both residential heating and industrial operations.
Crude oil markets also experienced gains on Monday, with prices advancing 2.2%. This movement created upward momentum for oil-linked gas contracts, compounding the price pressures from the shipping incident.
Rising Insurance Premiums Compound Supply Concerns
Market participants reported that LNG vessels continue to transit the strait, though under heightened security protocols. While physical flows remain intact, the risk assessment for the region has fundamentally shifted.
War-risk insurance premiums for vessels transiting the area have increased substantially. Insurance underwriters are incorporating the elevated threat of security incidents into their pricing models. These additional expenses ultimately flow through to European wholesale gas markets.
The timing presents particular challenges for European energy buyers. The market is entering a phase where even modest supply interruptions could generate disproportionate price impacts across the region.
Energy analysts are now monitoring whether tensions in the Strait of Hormuz continue to escalate. A prolonged disruption to LNG transit through this vital corridor could drive prices significantly higher in the coming weeks.
The Dutch TTF contract serves as the primary pricing reference for European gas commerce. Monday’s advance to multi-month peaks underscored how rapidly geopolitical developments can reshape energy market dynamics.
While LNG deliveries are currently proceeding, the market has already begun incorporating elevated risk premiums into pricing. Industry participants and utility companies are maintaining close surveillance of developments in the region.
The trading session served as a stark illustration of European energy markets’ ongoing vulnerability to Middle Eastern geopolitical events, especially those affecting strategic shipping corridors like the Strait of Hormuz.
