We questioned how 2023–24 pension disclosures appeared to show a reduction in public sector pension liabilities and raised that this was counter intuitive.

It commented that pensions were currently about 1.9% of GDP and expected to fall to about 1.4% over the next 50 years. The Treasury agreed with the general point about being transparent about different ways of measurement in order to support debate.42
