History of a ‘missed opportunity’: Dutch colonial legacy and decolonization of the maritime economy in Indonesia

This study reassesses Indonesia's economic decolonization in the 1950s by examining why the nationalization of Dutch-owned maritime and trading corporations failed to generate a strong national maritime economy. Drawing on historical analyses of the shipping industry, state policy, and postcolonial economic structures, the study argues that the Dutch corporate legacy remained deeply entrenched even after political independence, thereby shaping Indonesia's economic vulnerabilities throughout the decade. Although nationalization created an unprecedented opportunity to restructure maritime trade, inter-island shipping, and related industries, Indonesia lacked the managerial capacity, skilled labour force, financial resources, and institutional coherence required to capitalize on the takeover of foreign economic assets. This study employs a qualitative historical research method combined with a historical political economy approach. It is based on a critical analysis of historical sources, including archival documents, government regulations, company records, statistical data, and contemporary newspapers from the 1950s and early 1960s. The findings suggest that nationalization became a politically motivated act rather than a coherent economic strategy, a condition exacerbated by fragmented policymaking, ideological polarization, and the mismanagement of formerly Dutch corporations. As a result, the expulsion of KPM and the nationalization of the “Big Five” trading houses did not translate into maritime independence. Instead, Indonesia inherited large corporate structures without the expertise necessary to sustain or further develop them. The study concludes that the late 1950s should be understood not only as a period of anti-colonial consolidation but also as a critical lost opportunity to build a modern and competitive maritime economy. These findings contribute to broader debates on economic decolonization, state capacity, and maritime development in postcolonial Southeast Asia.
