Winter Is Coming: Europe Faces Twin Diesel And NatGas Crunch

Samantha Dart, co-head of global commodities research at Goldman Sachs, began the week by telling Bloomberg TV that the global diesel-supply crunch is "what keeps her up at night." She followed up Wednesday with a client note warning that European natural gas storage levels are also lagging the seasonal average ahead of the winter heating period.

Benchmark TTF futures have fallen 7% this week to about 54 euros per megawatt-hour, but Dart maintained her 60-euro balance-of-third-quarter forecast. She noted that Northwest European LNG imports missed July expectations by 2.1 million tons on an annualized basis, leaving storage just 43% full at month-end versus the 45.5% projected.

The latest Bloomberg data shows that Europe's NatGas storage is about 57.87% full, roughly 18 percentage points below the 2009–25 average.

"Specifically, the July miss in European LNG imports (and the resulting miss in storage fill) vs our expectations suggest that European gas storage still has some catching up to do, while LNG supply availability remains uncertain," Dart wrote in the note.

Dart continued, emphasizing that Europe must accelerate NatGas injections to reach her 67% storage target by the end of October. Higher potential Qatari exports, weaker Asian spot demand and reduced Egyptian imports could free additional cargoes for Europe, though an early drop in TTF prices risks redirecting LNG back toward Asia.

Dart warned that if Gulf energy exports recover only gradually, December TTF prices may need to exceed 100 euros to curb Asian demand. A faster reopening of the Hormuz maritime chokepoint could push prices to 40 euros.

Dart continued:

On net, we still see risks to our winter TTF price forecast skewed to the upside. In a scenario where Middle East energy exports normalize only gradually through 2027, we estimate that Dec26 TTF would likely need to move above 100 EUR/MWh, 110% above our 50 EUR/MWh base case, to significantly discourage Asia LNG demand. In contrast, we estimate that a faster-than-expected ramp of Hormuz flows would allow TTF to sell off back in line with the coal-to-gas switching threshold of 40 EUR/MWh, 20% below our current Dec26 TTF price base case.

Putting it all together, if disruptions in the Hormuz persist, Europe could enter winter with NatGas and diesel inventories well below seasonal norms, setting the stage for another surge in energy prices.
