**Deck**: The International Energy Agency warns that if the Strait of Hormuz stays disrupted and Europe faces a cold winter, gas storage on the continent could sink to around 10% by spring. Such low stocks would complicate withdrawals late in the season and drive up the cost of refilling storage for the following year.

Europe’s gas buffer could shrink to a thin margin if tensions with Iran keep pressure on shipping around the Strait of Hormuz and winter temperatures drop.

The International Energy Agency has warned that a prolonged Hormuz closure combined with a cold winter could leave European gas storage about 10% full by the end of the heating season. The figure is presented as a scenario, not a forecast, but it illustrates how closely European energy security is now tied to developments far beyond its borders.

Storage at such low levels would not be empty, yet withdrawing gas from nearly depleted sites is technically harder and less flexible. Grid operators would have less room to respond to a late cold spell or to cushion further supply disruptions.

The consequences would carry over into the next year. Storage caverns that end winter at around 10% must be refilled more aggressively during spring and summer. That means European buyers would need to secure extra cargoes in a tight global market, bidding against other importers and likely driving up prices.

Higher refilling costs would feed through into energy bills and could revive pressure on energy‑intensive industries that cut production during earlier price spikes. Companies might again face decisions on curbing output, shifting operations, or passing costs on to customers.

The IEA’s warning underscores that conflict and instability near Hormuz threaten not only oil flows but gas supplies as well, because many liquefied natural gas shipments either originate in the Gulf or pass near it. Even without a full closure, higher insurance premiums and rerouting can thin the flow of cargoes enough to affect balances.

Diplomatic efforts over Iran’s position and over navigation around Hormuz therefore sit alongside technical gas policy decisions inside Europe. Signals to watch include tanker traffic patterns near the strait, the pace of European gas storage injections and withdrawals, and any changes in EU emergency planning or storage targets that reference the IEA’s 10% scenario.
