Joint Pledge to Keep the Strait of Malacca Open and Secure
On July 6, 2026, at the Singapore-Indonesia Leaders’ Retreat in Jakarta, Prime Minister Lawrence Wong and President Prabowo Subianto reaffirmed their commitment to keep the Strait of Malacca open, safe and accessible to all vessels, stressing maritime security and freedom of navigation.
Strategic Context and Recent Developments
The Strait of Malacca links the Indian Ocean and South China Sea and carries a large share of global trade and energy shipments. Disruptions in the Strait of Hormuz during the Iran-U.S. conflict underscored the importance of alternative routes. Earlier in 2026, Indonesia’s finance minister floated a possible transit levy, sparking regional concern.
Data on Traffic and Economic Significance
In 2025 the strait handled over 102,500 vessel transits—about 22 % of global maritime trade—and moved roughly 23 million barrels of oil daily. The U.S. Energy Information Administration reports that 29 % of world seaborne oil passed through the strait in early 2026. Its narrowest point is 2.7 km wide and average depth 25 m, creating a bottleneck.
Official Statements & Diplomatic Position
Both leaders said the littoral states are strategically aligned and must uphold navigational rights under UNCLOS and customary law. They pledged coordination with Malaysia and Thailand to ensure security, deter piracy, pollution and accidents, and reaffirmed ASEAN’s principle of peaceful dispute resolution. Singapore’s MFA noted continued cooperation during Singapore’s ASEAN chairmanship in 2027.
Criticism & Opposition
Indonesia’s earlier levy suggestion drew criticism from Singapore’s Foreign Minister Vivian Balakrishnan and neighboring states, who warned that UNCLOS forbids fees for mere transit. Analysts stressed the legal basis for free passage, and the lack of a clear levy policy created uncertainty.
Conflicting Reports & Gaps
Sources differ on the levy’s seriousness. President Prabowo mentioned potential revenue from a three-way split among Indonesia, Malaysia and Singapore, yet officials later reiterated a ‘no-levy’ stance. No concrete plan or timeline has been presented.
Implications for Global Trade and Regional Security
Keeping the strait open preserves supply-chain continuity for energy and cargo, mitigating price spikes seen after Hormuz disruptions. The pledge also bolsters regional stability by aligning littoral security cooperation and supporting ASEAN’s maritime governance role.
