From maritime chokepoint politics and security to blue-economy resilience: Economic transmission, naval modernisation and disaster risk in Indonesia’s Malacca–Sunda Corridor

This article examines how disruptions across the Malacca–Sunda maritime corridor affect Indonesia’s energy security, trade competitiveness, coastal livelihoods, and fiscal resilience, while questioning the economic effectiveness of naval-centred maritime security strategies. Employing a comparative qualitative approach, the study integrates maritime oil-flow data, Indonesia’s 2024–2026 economic indicators, blue-economy policies, and disaster-risk financing evidence. Findings reveal four interconnected economic transmission mechanisms: energy supply and price volatility, shipping and insurance costs, port-network disruptions, and ecological and fiscal vulnerabilities. The analysis demonstrates that geopolitical tensions surrounding maritime chokepoints expose structural limitations in Indonesia’s maritime connectivity and economic resilience, particularly across coastal and archipelagic regions. It proposes a Chokepoint Resilience Capacity Assessment as an exploratory policy framework. The study argues that sustainable maritime resilience requires integrating naval capabilities with port development, inclusive coastal economies, energy diversification, environmental protection, and proactive disaster-risk financing within Indonesia’s broader geopolitical strategy.
