Pension funds managing £1.7tn in assets are urging UK Chancellor Rachel Reeves to revamp fiscal rules to promote more infrastructure and green energy investment. They want the government’s debt rules adjusted to recognize the value of assets created by such spending, rather than treating it purely as a liability. Current rules discourage public co-investment, limiting potential partnerships with pension funds. This change could unlock billions for future projects, aligning with the UK’s net zero goals. The proposal will be discussed with Treasury officials ahead of an international investment summit next week.
