Between State Control and Banking Power: Spanish Banking Supervision Under Franco (1940–1975)

This article analyzes the evolution of banking supervision in Spain under Franco’s regime (1939–1975), highlighting how political and economic factors shaped oversight in an authoritarian setting. Two phases emerge. In the 1940s–50s, supervision—lodged in the Ministry of Finance—was weak, poorly staffed, and focused on enforcing banks’ oligopolistic interest rate agreements, reflecting regulatory capture. Following the 1959 Stabilization Plan, rising external pressure, domestic concerns about oligopolistic practices, and the 1962 Banking Law prompted reform. Supervision shifted to the Bank of Spain with the establishment of the Private Banking Inspection Service, resulting in more frequent inspections and gradual formalization of supervision. Archival records indicate that by the 1970s, inspections had become more frequent and rigorous, signaling a cautious shift toward risk-based oversight. However, the reforms remained incomplete. Persistent systemic vulnerabilities culminated in the severe banking crisis of 1977–1982, underlining the limitations of supervisory transformation under authoritarian rule.
