Norway, a country of 5.5 million people that discovered oil off its coast in 1969, has built the world's largest sovereign wealth fund — worth more than $2 trillion in 2026 and holding stakes in roughly 1.5 percent of all publicly listed shares on the planet — meaning every Norwegian citizen effectively owns nearly $400,000 of the fund on paper

A country of 5.5 million people owns, through a single state fund, close to one and a half per cent of every listed company on the planet.

It has a formal name, the Government Pension Fund Global, though most people still call it Norway’s Oil Fund. By early 2026 it held assets worth more than $2 trillion, spread across roughly 7,200 companies, and stood as the largest sovereign wealth fund in the world. One figure tends to stop people: the per-head one. Split a little over $2 trillion among 5.5 million citizens and each notional share comes to roughly $385,000 on paper. Nobody can withdraw it. It is a claim on a collective asset, not a bank balance.

That number is real. What it does and does not mean is the more useful question.

Where the money came from

Norway found oil off its coast in 1969, when one of the largest offshore fields then known was discovered in the North Sea. That wealth arrived in a country that was already prosperous and well governed, which turns out to matter. Rather than spend the windfall as it came in, the government eventually built an institution to hold it. Legislation created it in 1990, and the first money went in during 1996, as the managers set out in their account of the fund’s origins.

One design choice shaped everything after: the fund invests only abroad. Keeping the money in foreign assets stops a flood of petroleum revenue from pushing up the krone and hollowing out the parts of the economy that have nothing to do with oil, the pattern economists call Dutch disease.

The rule that does the real work

Its headline size is less interesting than the constraint placed on spending it. Under a fiscal rule adopted in 2001, the government may draw only the fund’s expected real return each year, leaving the principal intact for people not yet born. Initially that ceiling sat at 4 per cent. In 2017 it was lowered to 3 per cent, a change made after an expert commission argued the earlier figure was too generous for a lower-return world, as documented by the Norwegian School of Economics.

That single rule is why the fund kept growing rather than being spent. It is also why Norway is the case study people cite whenever a country wants to avoid the resource curse, the tendency for sudden mineral wealth to breed corruption and boom-bust chaos rather than lasting prosperity.

What 1.5 per cent of the world looks like

Ownership on this scale means the fund holds meaningful stakes in most of the companies a reader would recognise, with Apple, Nvidia and Microsoft among its largest positions. It returned 15.1 per cent in 2025 and booked a profit of about 2.36 trillion kroner, close to $247 billion, which NBIM records as its second-highest annual return in krone terms, behind the record set in 2024. Technology, financial and mining stocks did most of the lifting, as the fund’s annual report sets out.

The number worth holding onto is a quieter one. Even in that strong year it trailed the benchmark it measures itself against by 28 basis points, its third consecutive year of falling short of that yardstick, as Bloomberg noted. A holding this large mostly moves with the world’s markets. When they rise it looks brilliant. When they fall it will look the opposite, because $2 trillion in global equities is not a safe harbour.

Why the model is harder to copy than it looks

The tempting reading is that any petro-state could do the same. In practice the opposite holds. Norway’s low corruption, its strong institutions and its habit of political consensus were in place before the oil, and the fund reflected that culture rather than creating it. Countries that struck oil without those foundations have rarely produced anything close.

The rule under pressure

There is a live tension inside the Norwegian system. Fund withdrawals now cover more than a quarter of the annual budget, an all-time high, which means the larger the fund grows, the more it can be leaned on, and the harder the discipline is to hold. In 2025 the country’s Fiscal Policy Committee recommended that the government study replacing the return-based rule with one tied to the fund’s cash flow, arguing that the present rule leaves the budget exposed to a sharp fall in the fund’s value, as reported by IPE.

Whether the government takes that advice, and revises the rule that made the fund what it is, is the thing worth watching.
