‘Mind the MacMillan Gap. Off-Balance-Sheet Fiscal Agencies in Britain’s Post-War Industrial Financing, 1945-1973’ (with Olan McEvoy, Moritz Kapff, and Andrei Guter-Sandu)

Following World War II, Britain faced mounting industrial financing challenges amid economic decline, structural weaknesses, and a finance sector ill-equipped to support SME growth and industrial modernisation. While research has extensively analysed Britain’s post-war reconstruction and industrial policy, the role of off-balance-sheet fiscal agencies (OBFAs)—semi-autonomous institutions operating outside core state balance sheets—remains underexplored. This paper addresses this gap by presenting a historical case study of three British OBFAs: the Industrial and Commercial Finance Corporation (ICFC), the Finance Corporation for Industry (FCI), and the Industrial Reorganisation Corporation (IRC), tracing their evolution and impact from 1945 to 1973. Using extensive archival research from the British National Archives and Bank of England, combined with transactional balance sheet flow analysis in the context of the Monetary Architecture framework, the study reveals how these institutions balanced market autonomy and state objectives to fill critical capital gaps, support post-war reconstruction, and drive industrial growth. The ICFC and FCI pioneered new forms of patient capital for SMEs and larger industries respectively, while the IRC marked a shift toward active state-led industrial restructuring through mergers and modernisation initiatives in response to mounting international competition. The findings highlight how these OBFAs constituted vital yet overlooked nodes in Britain’s fiscal ecosystem, mediating between the City, the state, and industry in a period of economic transition. This analysis contributes to political economy debates on developmental finance and offers insights relevant for contemporary discussions about designing national development institutions aimed at fostering industrial growth.
