A Flow Map Reduced to a Handful of Arteries

The physical gas flow readings for 30 October 2026 are instructive for what they show — and for what they do not. At Emden EPT1, the entry point for the Norwegian Norpipe link, physical entry reaches 402.5 GWh per day. At the VIP TTF-THE-H point between the Netherlands and Germany, entry stands at 482.9 GWh/d, against 180.8 GWh/d in exit. Zeebrugge IZT, on the UK-Belgium interconnection, records 72.6 GWh/d in entry. At Tarvisio, on the TAG axis between Austria and Italy, entry reaches 144.4 GWh/d.

On the other side, several points remain stubbornly at zero, both in entry and exit, on both dates observed: Mallnow (Poland-Germany, Yamal), VIP Waidhaus (Czech Republic-Germany) and Baumgarten TAG (Slovakia-Austria). The readings say nothing about the causes of these zeros. They establish only that, at these points, no molecule flowed on 30 and 31 October.

An 80% Drop in Twenty-Four Hours

The next day, the picture changes abruptly. Entry at Emden EPT1 falls to 77.6 GWh/d, roughly 81% less. Exit at VIP Oberkappel, between Austria and Germany, drops from 112.5 to 22.6 GWh/d, a decline close to 80%. At Tarvisio, the reported entry of 144.4 GWh/d disappears, and an exit of 17.2 GWh/d appears instead. The day's figures are therefore not only lower — they also differ in their apparent direction.

Overinterpretation must be avoided. 31 October is a Saturday, and the file does not rule out a calendar effect or provisional values. Several lines are moreover missing: entry at Zevenaar, on the Netherlands-Germany side, remains "N/A" on both dates, and its exit is reported only for 30 October (52.7 GWh/d). An absent value does not equal a zero flow.

From the Strait of Hormuz to the Price of Gas

This physical picture takes on meaning in the market context. Since the outbreak of war against Iran on 28 February, the closure of the Strait of Hormuz has disrupted oil and gas flows from the Gulf. The mechanism is well known: when part of LNG supply disappears, Asian and European buyers compete for the remaining cargoes, and producers outside the Gulf capture the difference.

The case of Cheniere illustrates this. The US group raised its 2026 EBITDA forecast for the third time this year, now set between $8.75bn and $9.25bn. About $250m of that increase comes from more than doubled netbacks, an effect directly tied to the Hormuz crisis. QatarEnergy for its part agreed to buy 4 million tonnes per year from Cheniere, with deliveries from the 2030s. The buyer is itself a major LNG seller — which says a great deal about the value of diversification.

This is where the flow map matters. If the Eastern corridors remain at zero, Europe has no alternative pipelines to cushion an LNG shock. It depends on Norway, whose flow at Emden varies by more than 300 GWh/d in a single day in the readings, and on LNG, paid at the global price. Against this backdrop, European gas breaking through 101 euros for the first time since 2022 appears consistent with the sequence described. The headline announcing it, however, specifies neither the index nor the unit, and it is not enough to prove the link.

Electricity: A One-to-Three Gap

Electricity prices on 30 October point the same way, without proving it. Day-ahead settles at EUR 254.14/MWh in Switzerland, 250.85 in the Czech Republic, 250.56 in Denmark (DK-1 zone) and 211.19 in Portugal. Finland, at EUR 77.51/MWh, trades roughly 3.3 times cheaper than Switzerland. In markets where gas often sets the marginal price, expensive gas feeds through to electricity. The file does not provide the generation mix of these zones: the gap with Finland is therefore compatible with this reading, without being proof of it.

What the Data Do Not Say

Several elements call for restraint. The first is the brevity of the series: two days of flows do not make a trend, and the 80% drop on 31 October may reflect a Saturday, revised nominations or incomplete publication. The second is the absence of storage data, essential for judging winter supply security. The third is the message from the CEO of TotalEnergies, who expects no gas shortage in Europe this winter. The fourth is the oil move: Brent lost 7.63% on 2 November to close at $104.77 a barrel, on hopes of US-Iranian talks. The file does not indicate whether gas followed.

A Structural Fragility, Not an Announced Shortage

What can reasonably be concluded comes down to three points. The flow architecture is narrow: a few points concentrate the volumes, others are at zero. It is volatile: major arteries can lose 80% of their throughput from one day to the next, whatever the reason. Finally, it is exposed to an LNG market that the war in Iran has durably made more expensive, as Cheniere's results attest. That is enough to speak of vulnerability to prices. It is not enough to announce a physical rupture, which neither storage nor the file's forecasts support. What comes next will depend on flow confirmation over several weeks and on the evolution of talks around Hormuz.
