Should Britain copy Norway?

As Britain debates Net Zero, energy security and the future of North Sea drilling, an older argument has returned with renewed force: that the UK squandered its oil wealth while Norway built a sovereign wealth fund worth more than a trillion dollars.

It is an appealing story. If only Britain had saved its North Sea revenues like Norway, the argument goes, it could have transformed its long-term economic fortunes, preserved its industrial base and avoided decades of relative decline.

But the comparison rests on a misunderstanding of both countries’ economic realities.

Britain and Norway did not face the same conditions and make different choices. They faced fundamentally different structural realities: different populations, different oil reserves, different production timelines and different fiscal pressures. The idea that Britain simply ‘missed its chance’ is less an economic analysis than a hindsight morality tale – one that reflects a broader tendency to reinterpret complex structural change as simple political failure.

The first problem is scale.

Norway has a population of around 5 million people. Britain has almost 70 million. Oil wealth distributed across a small population can generate enormous per-capita surpluses. Spread across a much larger and more complex economy, the same revenues become far less transformative.

What appears, in retrospect, to have been a squandered fortune was, in reality, a more limited resource facing far greater demands.

The timing of Britain’s oil revenues also mattered enormously.

UK North Sea production ramped up rapidly in the late 1970s and peaked in the early 1980s — just as global oil prices began to turn. The collapse in prices during the mid-1980s sharply reduced what had initially looked like a major windfall.

At their peak, UK oil revenues reached roughly £10–12 billion annually, or around 3–4% of GDP, but only briefly. Oil and gas formed an important but ultimately supplementary part of the economy. Britain never became a petrostate.

Norway’s experience was very different. Its oil sector expanded later and benefited from higher prices over a much longer period. At times, oil and gas accounted for more than 20% of Norwegian GDP and roughly half of exports.

Norway also benefited from larger and longer-lasting fields, giving it a more stable and durable revenue base. Many British fields were smaller, depleted faster, and were more vulnerable to swings in global prices.

The contrast is clear. In Britain, North Sea oil was a short-lived and volatile supplement to a large economy. In Norway, it became a dominant national asset.

A sovereign wealth fund depends on consistent surpluses over long periods of time. Britain’s revenues peaked early, then weakened just as conditions deteriorated.

This was not a Norwegian-scale fortune. It was a brief windfall arriving at a difficult moment.

When oil revenues peaked in the early 1980s, Britain was emerging from stagflation and still living with the legacy of the IMF crisis of the 1970s. Interest rates and borrowing costs were extraordinarily high. Government bond yields frequently sat between 10% and 15%, while mortgage rates approached 20%.

In that environment, the economics of debt looked very different from today.

Even though overall public debt was lower than current levels, servicing that debt was dramatically more expensive. Every pound of borrowing carried a heavy and immediate financial cost.

Using oil revenues to reduce borrowing pressures and stabilise the economy was therefore a rational choice at the time.

Norway existed in the same high-interest-rate world, but with far fewer immediate fiscal pressures and a far more concentrated resource boom.

It is often argued that Britain should have used North Sea revenues to support domestic industry. But this misunderstands what a sovereign wealth fund is. Norway’s Government Pension Fund Global was structured specifically to invest abroad, avoid distorting the domestic economy, and limit political pressure over spending. It did not support Norwegian industry, and it was never intended to.

Using North Sea revenues to support Britain’s industrial base may itself have been counterproductive. By the late 20th century, British industry was already under pressure from global competition, technological change, and the broader shift toward service-led economies visible across the developed world.

Britain was not unique in confronting deindustrialisation, though as the world’s first industrial nation it faced these pressures earlier and more intensely than others. The central challenge was therefore not how to preserve older industrial structures, but how to support the transition away from them.

Successive governments had already attempted various forms of industrial intervention, often with disappointing results. In firms such as British Leyland and British Steel, state support frequently delayed adjustment more than it drove renewal.

In that context, using oil revenues to support public spending and reduce debt helped alleviate many of the painful social and economic consequences of deindustrialisation.

They were never going to prevent it.

Britain did not possess the same scale of revenues, field durability, population dynamics, or fiscal circumstances that underpinned Norway’s sovereign wealth fund.

Nor is it clear that using North Sea revenues to support domestic industry would have prevented deindustrialisation in an economy already undergoing major structural change.

The claim that Britain simply squandered a Norwegian-style opportunity therefore misunderstands both the nature of sovereign wealth funds and the economic realities of the period.

Oil revenues were not wasted. They helped maintain stability during the painful transition away from Britain’s declining industrial base.
