Capitalise the National Wealth Fund

Policy baseline

Labour pledged GBP 7.3bn over the Parliament for a National Wealth Fund. The fiscal issue is capital risk, not only annual spending.

• Targets ports, steel, hydrogen and clusters.
• Financial assets may offset some debt impact.
• Crowding-in is not automatic.

Core trade-offs

The direct beneficiaries are supported firms and industrial regions. The costs fall mainly on taxpayers bearing project and opportunity risk. The main economic question is public capital may crowd out private investment.

• Supported firms and industrial regions gain most directly.
• Costs fall mainly on taxpayers bearing project and opportunity risk.
• Key risk: public capital may crowd out private investment.

Fiscal impact by 2028-29

+GBP 0.2bn to +GBP 4.0bn. Central estimate: +GBP 1.5bn.

• Positive numbers mean net fiscal cost; negative numbers mean Exchequer savings.
• Main channel is annualised capital injection and project risk.
• Returns may appear later but are not assumed upfront.
• Additional private investment is the weakest assumption.
• This is not an official costing.

Economic impact by 2028-29

• Jobs: Green construction and supply-chain jobs rise; fossil-linked jobs face transition risk.
• Wages: Skilled retrofit and energy workers may gain; households gain only if bills fall.
• Prices: Upfront costs are high; long-run energy bills may fall if delivery succeeds.
• GDP / productivity: Potentially positive through lower energy imports and innovation; delivery bottlenecks can weaken returns.

Assessment

This is a real trade-off, not a free gain. Supported firms and industrial regions benefit, while taxpayers bearing project and opportunity risk bear most costs. Overall output depends on behaviour, capacity and pass-through.

Confidence: Medium-low. Higher on the policy target and fiscal channel; lower on behaviour, pass-through and economy-wide effects.

Main risks

• Supply-chain limits: Skills, grid connections and materials can delay delivery.
• Cost overruns: Retrofit and energy projects often face uncertain unit costs.
• Weak additionality: Public money can replace private investment rather than add to it.

Safeguards

• Publish project pipelines and unit costs.
• Use competitive procurement where possible.
• Report additional private investment mobilised.
