Putin Is Closing the Pipeline Taps: What the End of Russian Gas Means for Markets

The pipeline taps are closing, and this time the closure is not a negotiating tactic. It is a structural rupture.

For half a century, Russian gas flowed west through pipelines with a reliability that bordered on the theological. Soviet gas, then Russian gas, arrived in Germany, Italy, and Central Europe through every crisis of the Cold War and every convulsion after it. The system survived the fall of the Berlin Wall, the collapse of the Soviet Union, and successive rounds of sanctions. That record of dependability was not incidental. It was the product. Gazprom sold certainty, and Europe bought it for decades, because certainty was cheaper than the alternative.

That arrangement is now finished, and it is worth being clear about what has actually happened.

The dismantling has been incremental, deliberate, and is now essentially complete, and the two sides are racing each other to the finish line. The sabotage of Nord Stream in September 2022 removed the flagship route under the Baltic. Poland stopped taking Russian gas through Yamal the same year. On 1 January 2025, the transit agreement through Ukraine expired and was not renewed, ending the last major flow of Russian pipeline gas into Central Europe. Gazprom's pipeline exports to Europe fell 44% in 2025 to roughly 18 billion cubic metres, the lowest annual volume since the mid-1970s, back to the levels of the early Siberian trade.

TurkStream, through Turkey, is now the sole remaining pipeline route, and it is running near capacity (about 51.9 million cubic metres a day in August 2026, up 3% year on year), feeding a shrinking set of customers, principally Hungary and Slovakia. Meanwhile Russian LNG, which kept flowing even as pipeline volumes collapsed, is being legislated out: Regulation (EU) 2026/261, published in January 2026, bans new short-term Russian LNG contracts from late April 2026, bans Russian LNG outright from early 2027, and prohibits the remaining Russian pipeline imports entirely by late 2027. And in March 2026, with the Iran crisis paralysing the Strait of Hormuz and energy prices spiking, Putin mused on state television that it might be "more profitable" for Russia to stop supplying Europe right now and reorient toward buyers willing to pay more. He called it thinking out loud. The market should price it as anything but.

The market reaction, on the surface, has been surprisingly composed. Russia's share of EU gas imports has collapsed from roughly 45% in 2021 to about 12% in 2025, leaving it the fourth-largest external supplier behind Norway, the United States, and Algeria. Storage is reasonably full. Europe rebuilt its supply base with extraordinary speed: LNG import capacity expanded aggressively, Norwegian pipeline output rose, demand fell through conservation and industrial restructuring, and buyers outbid Asia for cargoes when they had to. On paper, Europe solved the problem.

I would argue the problem is not solved. It has been repriced.

Here is the structural reality that matters. Europe replaced cheap, reliable, continuous pipeline supply with expensive, flexible, globally competed LNG cargoes. That substitution works when global LNG supply is loose. It works far less well when Asian demand rises, when a cold winter draws down storage, or when a single export facility goes offline, and we just watched precisely that stress test. The closure of the Strait of Hormuz in early 2026 shut down Qatari LNG output, and European prices surged within days. The system held, but only by paying. Nor is the new dependence remotely diversified: 57% of the EU's LNG came from the United States in 2025, and on current contracting that could reach 75 to 80% by 2030. Europe did not abolish dependence. It transferred it. The old Russian gas was cheap because it was committed. The new gas is available because it is uncommitted, and availability at the margin is the most expensive commodity in any market.

The consequences are now moving through markets in ways that deserve close attention.

First, European industrial competitiveness has taken a permanent haircut. The chemicals, fertiliser, glass, and metals sectors that were built on the assumption of cheap gas are structurally uncompetitive against US producers enjoying domestically priced energy and Asian producers with cheaper alternatives. Some of that capacity will never return. For anyone allocating capital into European industrial assets, the energy cost curve is now the first question, not the last.

Second, the global LNG market has become the genuine geopolitical battleground. Every cargo is now a foreign policy decision. The United States, Qatar, and increasingly Australia sit on the supply side of a market where European security demand meets Asian growth demand, and the competition between those two basins sets the marginal price of energy for the world. Freight rates, cargo re-routing, and destination flexibility are no longer shipping variables. They are strategic ones. As an Australian operator, I will note plainly: this country is one of the largest LNG exporters on earth, and the permanent remapping of global gas flows is a generational commercial tailwind for Australian energy infrastructure and the service industries around it.

Third, energy security has become a strategic theme in its own right, and it is converging with the single largest demand story of this decade. The AI build-out has flipped the breakers on the power grid, and the data centre pipeline is stalled not for want of capital but for want of megawatts. Gas-fired generation is the bridge fuel for that demand in most of the world. A Europe that has structurally surrendered pipeline gas, and a world where AI is re-electrifying demand faster than grids can expand, is a world where flexible gas capacity is strategically critical. Storage infrastructure, floating regasification, peaking plants, and grid interconnection are no longer utility infrastructure. They are geopolitical infrastructure.

Fourth, volatility itself has become structural. Russian supply was the stabiliser of the global gas system for fifty years. Its removal has taken the largest swing supplier out of the market and replaced it with a demand-side scramble for flexible cargoes. In commodity markets, when you remove the system's shock absorber, you do not get a new equilibrium. You get wider oscillation around a higher average. Anyone operating in this environment should plan for price ranges that look irrational by historical standards, because the historical standards were set by a system that no longer exists.

Fifth, watch the monetary and safe-haven channel. An energy-importing Europe absorbing structurally higher input costs carries a persistent terms-of-trade drag, which flows into inflation stickiness, into the European Central Bank's reaction function, and into the euro. Meanwhile, every escalation in the pipeline story has historically moved in tandem with gold, and that correlation has strengthened as sanctions regimes have deepened. The energy story, the inflation story, and the safe-haven story are now the same story told through three instruments.

And what of Russia itself? The cutoff has cost Moscow tens of billions in annual revenue, and the pivot toward China has only partially replaced it, at discounted prices and with the immense capital cost of new eastern pipeline infrastructure. The corporate toll is stark: Gazprom, the world's third-largest company with a market capitalisation above $330 billion in 2007, is worth roughly $40 billion today. The remaining European business now rests on two landlocked customers, Hungary and Slovakia, whom Putin pointedly names as "reliable partners" , a reminder that even the last flows are political, not commercial. The gas weapon has been fired, and its principal effect has been to destroy the credibility of Russian energy as a long-term contractual partner. Twenty years of "reliable supplier" positioning was spent in twenty-four months. No amount of future diplomacy easily restores the confidence that a supply relationship requires, and that, more than any single price, is the true commercial cost of the cutoff.

The lesson I would take from all of this is simple. Energy has stopped being a commodity market and has become a security market. The price of gas in Europe is now set by geopolitical posture as much as by supply and demand curves. That means the old analytical frameworks, the ones that treat an outage as a supply disruption and a restoration as a return to normal, will systematically misprice this environment. Normal is gone. What replaced it is a market where the taps are controlled by actors whose incentives are strategic rather than commercial, and every position in the energy complex, from a European factory to an Australian LNG project to a gas-fired power contract, is now implicitly a position on how long that lasts.

For disciplined operators, that is not a warning. It is the environment. And in this environment, the advantage sits with those who treat energy security as a first-order commercial variable rather than a line item: those who build optionality into supply, structure around volatility rather than through it, and understand that the age of cheap, politically guaranteed energy in Europe ended the moment the pipelines began to empty.
