We are concerned that departments are not maintaining institutional knowledge relating to ‘at risk’ companies and sectors. HM Treasury monitors the health and resilience of the corporate sector as a whole and the Department for Business and Trade oversees industry and different priority sectors and has a role in responding to economic shocks. It is the responsibility of individual departments to monitor the health of their sectors, and those at the centre of government say they are not aware of any one sector that is more at risk than others. However, a high turnover of staff in government means that corporate knowledge held by departments, which may be commercially sensitive and therefore restricted to a small handful of individuals, is at risk of being lost. HM Treasury spending teams act as the filter for warnings from departments, but turnover of staff in HM Treasury is historically even higher. Recommendation 2: In the Treasury Minute response, HM Treasury and the Cabinet Office should set out how they will support departments to maintain a continuous level of knowledge about risks to companies and supply chains in sectors that are relevant to their departmental duties and objectives.
