The Implementation of Local Professionalism: Integrating De Javasche Bank Assets in Surabaya Post-Nationalization (1951–1953)

The nationalization of De Javasche Bank (DJB) into Bank Indonesia (BI) via Law No. 11 of 1953 was fundamental to establishing Indonesia's monetary sovereignty. This study argues that the success of this high-stakes political decision was critically dependent on the micro-level administrative competence realized at strategically vital regional nodes. Focusing on the DJB Surabaya branch—the principal clearing center for Eastern Java—we utilize a qualitative historical methodology employing both macro-level institutional reports and localized archival sources to trace the implementation process. Our analysis posits that the swift and non-disruptive integration of the branch was a defining expression of professional patriotism, where national dedication was channeled into bureaucratic efficiency rather than military action. This success was executed through three synchronized strategic maneuvers: (1) Physical Asset Securitization and Symbolic Repurposing (securing reserves and rebranding the colonial structure); (2) Systemic Operational Continuity (seamlessly maintaining the regional credit clearing mechanism); and crucially, (3) Rapid Human Resource Decolonization (accelerated promotion and technical training of indigenous staff). The Surabaya case provides empirical validation of the newly independent Republic’s state capacity to manage complex central banking operations, underscoring the vital, yet often overlooked, role of regional administrative elites in post-colonial state-building.
