Green - Finance
Create regional mutual banks
Use public capital to support regional mutual banks and local business lending.
Last updated: May 2026.
Policy baseline
Green economic policy supports regional mutual banks and local finance. Fiscal risk depends on capitalisation, lending quality and default rates.
- Targets SMEs and underserved regions.
- Credit constraints may be real in some areas.
- Bad lending creates taxpayer losses.
Core trade-offs
The direct beneficiaries are small firms and underserved regions. The costs fall mainly on taxpayers bearing credit risk. The main economic question is politicised lending can misallocate capital.
- Small firms and underserved regions gain most directly.
- Costs fall mainly on taxpayers bearing credit risk.
- Key risk: politicised lending can misallocate capital.
Fiscal impact by 2028-29
+GBP 1.0bn to +GBP 8.0bn. Central estimate: +GBP 2.5bn.
- Positive numbers mean net fiscal cost; negative numbers mean Exchequer savings.
- Main channel is the scored tax, spending or delivery change.
- Offsets depend on tax receipts, behaviour and pass-through.
- Range reflects uncertain implementation and economic response.
- This is not an official costing.
Economic impact by 2028-29
- Jobs: Higher public employment or procurement demand; shortages may shift workers from private firms.
- Wages: Direct gains for funded staff or suppliers; taxes fund the transfer.
- Prices: Public prices rarely rise directly; private prices may rise if labour is scarce.
- GDP / productivity: Potentially positive if capacity improves; negative if bottlenecks or crowd-out dominate.
Assessment
This is a real trade-off, not a free gain. Small firms and underserved regions benefit, while taxpayers bearing credit 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
- Delivery bottlenecks: Staffing, procurement and capital constraints may stop extra money becoming better services.
- Crowding out: A tight labour market can shift workers from private firms rather than add capacity.
- Permanent baseline: Temporary programmes can become recurring spending commitments.
Safeguards
- Publish unit-cost benchmarks before rollout.
- Tie funding to measurable service capacity.
- Use staged delivery with independent audits.

Credit constraints
Some firms are credit constrained, so public finance can support investment when well targeted.
