What We Know About Britain's New £2bn Energy Wealth Fund

The UK Treasury calculated for the first time this week that Britain could have built a national oil fund worth roughly £1 trillion had it invested North Sea tax receipts since the 1980s rather than spending them, according to BBC News. The figure was produced by Treasury officials and disclosed alongside Wednesday's approval of the Jackdaw gas field, where Chancellor John Healey announced a new Energy Wealth Fund seeded with £2bn diverted from the existing National Wealth Fund, the BBC reported.

How did the Treasury arrive at £1 trillion?

The trillion-pound estimate is internal modeling, not an audited balance. Treasury officials took the UK's historical North Sea tax receipts — about £200bn — and modeled what that sum would be worth today if it had been invested continuously, with no withdrawals, and grown at a rate comparable to Norway's sovereign fund, the BBC reported. The exercise is retrospective and hypothetical; no such fund exists or ever existed in the UK.

"If we had done this when North Sea oil was first discovered in the 1980s, we'd have a British Sovereign Wealth Fund now that would be worth probably a trillion pounds," Chancellor John Healey said, as quoted by the BBC.

By the numbers

• £200bn — historical UK North Sea tax receipts used as the base case in Treasury modeling, per the BBC
• £1tn (roughly) — Treasury's estimated value today if those receipts had been invested and compounded at Norway-comparable returns, per the BBC
• $2.4tn — current size of Norway's sovereign wealth fund, built from the same North Sea basin, per the BBC
• £2bn — initial funding for the UK's new Energy Wealth Fund, redirected from the National Wealth Fund, per the BBC
• £3tn — UK national debt, which crossed that threshold the same week, per the BBC

Why does Norway's fund look so different from Britain's?

Norway's fund, drawing on the same North Sea reserves Britain taps, has grown to $2.4tn, the BBC reported. Norway draws down about 3% of the fund's value annually to cover roughly a fifth to a quarter of its government budget, including an additional drawdown during the coronavirus pandemic, according to the BBC. The fund is required to invest abroad and has benefited heavily from stakes in large US technology companies, the BBC reported.

Britain's new vehicle will not follow that model. The government intends to channel new North Sea revenue into the Energy Wealth Fund going forward, but it will be run differently from Norway's fund, according to the BBC — a distinction a Treasury insider framed directly: "Norway demonstrates the power of long-term investment: the government wants to learn from that principle, rather than copy its model wholesale," the person told the BBC.

One structural reason for the gap predates any UK policy choice: Norway's fund did not begin in earnest until 1996, more than two decades after North Sea production started, the BBC noted — meaning even Oslo's own piggy bank missed the earliest wave of revenue.

What will the new UK fund actually do?

The Energy Wealth Fund launches with £2bn redirected from the National Wealth Fund, the existing UK investment vehicle, Healey announced at the Jackdaw gas field approval, per the BBC. The chancellor's stated aim is for proceeds from oil and gas "coming ashore now" to be invested for future generations rather than spent immediately, the BBC reported. Unlike Norway's fund, there is no confirmed UK rule yet on annual drawdown rates or a mandate to invest only overseas.

What do critics say happened to the money?

A Treasury insider described the absence of a UK sovereign fund as a "missed opportunity," telling the BBC that "had we systematically invested those receipts, we could have built a huge national asset for future generations." Economists critical of the Thatcher-era approach argue peak North Sea revenue in the 1980s was spent on pre-election tax cuts, the BBC reported, while others have pointed to subsequent governments' spending choices as the cause. The BBC noted the debate has also featured in arguments from Scottish independence supporters and was raised by some government advisers as far back as the 1970s. The Treasury's calculation does not assign responsibility to any single government; it simply models the compounding cost of five decades without a dedicated fund.

The announcement arrived the same week UK national debt passed £3tn for the first time, the BBC reported — a juxtaposition the Treasury's own modeling now puts a number on.
