The Stranded Asset Reckoning: $7 Trillion in Fossil Fuel Infrastructure at Risk

On a February evening in 2024, Mike Coffin sat in his cramped London office, scrolling through quarterly earnings reports from the world's largest oil companies. The Carbon Tracker analyst had spent fifteen years building financial models for the energy sector, first at Morgan Stanley, then at this scrappy nonprofit that had made a career of telling fossil fuel executives things they didn't want to hear. Something in the numbers that night made him stop.

Shell had just written down $5 billion in liquefied natural gas assets. BP had quietly reduced the carrying value of its Gulf of Mexico holdings. ExxonMobil's upstream capital efficiency had declined for the third consecutive year. Individually, these were accounting footnotes. Together, Coffin realised, they were symptoms of something the industry had spent a decade denying: the physical infrastructure of the fossil fuel economy was beginning to lose its value before it had finished being used.

"I'd been modelling stranded asset risk for years," Coffin told me in March. "But this was the first time I could see it happening in real time, not as a projection, but as a present-tense accounting problem."

What the Balance Sheets Reveal

The concept of stranded assets — capital investments that lose their value before the end of their expected economic life — has haunted climate economics for over a decade. The term entered the financial lexicon in 2011, when Carbon Tracker published its first report warning that fossil fuel companies were overvalued because their reserves could never be safely burned. Back then, the argument was theoretical, premised on climate policies that might one day arrive.

The thing is: the policies have arrived, and so has something arguably more powerful — economics. The International Energy Agency's latest World Energy Investment report, published in June 2025, documents a transformation that would have seemed implausible a decade ago. Global investment in clean energy reached $2.2 trillion in 2025, nearly double the $1.3 trillion flowing into fossil fuels. Solar photovoltaic alone attracted more capital than all upstream oil and gas combined.

Carbon Tracker's new analysis, which Coffin led, attempts to quantify what this shift means for the physical infrastructure the fossil fuel industry has spent a century building. The numbers are stark: of the $15.2 trillion in oil, gas, and coal assets currently on corporate and sovereign balance sheets, roughly $7.1 trillion faces significant stranding risk if global demand peaks by 2030 and declines thereafter — a scenario the IEA now considers its central projection.

The Geography of Stranded Value

Not all fossil fuel assets face equal risk. The economics are merciless in their geography. Canadian oil sands, with production costs averaging $65 per barrel, cannot compete in a world where Saudi Arabia can profitably extract crude at $10. Arctic drilling projects, which require sustained prices above $80 per barrel to break even, look increasingly like infrastructure built for a market that will never exist.

The World Bank's latest Global Economic Prospects report, released in January 2026, devotes an entire chapter to what it calls "fossil fuel transition risk" — a polite term for the economic carnage that awaits countries whose economies depend on resources the world is learning to do without. Nigeria, where oil and gas account for 90% of export earnings, faces potential GDP losses of 8-12% by 2040 under the IEA's central scenario. Algeria, Iraq, and Angola confront similar arithmetic.

Here is what this means in practice: Norway, with its $1.7 trillion sovereign wealth fund, has spent two decades preparing for the end of its oil economy. Nigeria, with comparable petroleum resources but decades of misgovernance, has not. The energy transition is not just a climate story; it is a story about which nations built institutions capable of navigating structural change, and which did not.

The Uncomfortable Data

The fossil fuel industry disputes these projections, and their objections are not without merit. Global oil demand did not peak in 2023, as some optimistic forecasters predicted. It grew, reaching 102.2 million barrels per day in 2025, driven by aviation's post-pandemic recovery and petrochemical demand in Asia. Natural gas consumption has increased every year for the past decade.

OPEC's annual World Oil Outlook, published in September 2025, offers a radically different vision of the future. The cartel projects oil demand will not peak until after 2045 and will remain above 100 million barrels per day through 2050. In this scenario, stranded asset risk is minimal — the infrastructure will be needed, and the investments will pay off.

Who is right? The honest answer is: we don't know. Energy forecasting has a dismal track record. The IEA consistently underestimated solar growth for fifteen years. OPEC has consistently overestimated oil demand for the past five. The future is not a single scenario but a distribution of possibilities, and the stranding question is really a question about which tail of that distribution materialises.

The Financial System's Blind Spot

What makes stranded assets particularly dangerous is how the financial system accounts for them — or rather, doesn't. Standard accounting rules allow companies to carry assets at their original value until they are impaired, a determination that management makes with considerable discretion. A company can book a thirty-year oil field at full value even if the market has already concluded the field will be worthless in fifteen.

The Bank for International Settlements addressed this problem in a March 2026 working paper that has circulated nervously through financial regulatory circles. The paper, authored by economists in the bank's monetary and economic department, argues that fossil fuel stranding risk is systematically underpriced in credit markets. Banks lending to oil and gas companies are not adequately provisioning for the possibility that collateral — oil fields, refineries, pipelines — may lose value faster than loans mature.

"The transition risk is concentrated in exactly the institutions least prepared to absorb it," the paper concludes. European banks, which hold approximately $530 billion in fossil fuel exposure, face particular vulnerability. So do pension funds, which have historically favoured energy sector bonds for their reliable dividends — reliability premised on a demand trajectory that may no longer hold.

What We Still Don't Know

The stranded asset thesis contains an assumption that its proponents sometimes glide past: that stranding happens gradually, giving investors time to adjust. But energy transitions have not historically been gradual. The collapse of the American coal industry took less than a decade once natural gas prices fell. Kodak went from industry dominance to bankruptcy in twelve years after digital photography matured.

If oil demand declines faster than anticipated — if, say, battery costs fall another 50% by 2030, or if a major oil-importing nation like India implements aggressive electrification policies — the stranding could be sudden rather than orderly. In that scenario, the $7 trillion figure may prove conservative. The institutions holding those assets would face not a managed wind-down but a stampede for the exits.

Back in his London office, Mike Coffin has moved on to the next quarter's earnings reports. The writedowns continue. Shell announced another $2 billion impairment in January; Chevron took a $4 billion charge on its California refining operations. These are still rounding errors in the context of these companies' balance sheets. But Coffin sees a pattern that, once noticed, cannot be unseen.

"The market is starting to price transition risk," he says. "Not fully, not yet. But the gap between what these assets are worth on paper and what they're worth in a decarbonising world — that gap is closing. The only question is whether it closes slowly or all at once."

That question — gradual or sudden, orderly or chaotic — is the question that will determine whether the energy transition becomes a managed restructuring or a financial crisis. The infrastructure is there: the pipelines, the refineries, the platforms jutting into the North Sea. The capital has been spent. Now we wait to learn how much of it was wasted.
