Indonesia’s Proposed Malacca Strait Levy Triggers Regional Debate
4/24/2026, 12:59:10 PM
Core Event
On 22 April 2026 Indonesia’s Finance Minister Purbaya Yudhi Sadewa suggested that ships transiting the Strait of Malacca could be subject to a levy, citing Iran’s recent move to charge vessels in the Strait of Hormuz. He noted that revenue could be shared among Indonesia, Malaysia and Singapore, with Indonesia receiving the largest share because its stretch of the strait is the longest. Within hours, Purbaya qualified the remark as a “trial balloon” and emphasized that any implementation would require multilateral agreement.
Background & Context
Iran announced plans to impose tolls on the Strait of Hormuz after the February 2026 escalation of hostilities involving the United States and Israel. The Hormuz toll model, paid in Chinese yuan or cryptocurrencies, has been described as a wartime response that could set a precedent for other strategic chokepoints. The Strait of Malacca handles roughly 30 % of global trade, with about 200 ships per day and over 100 000 transits annually, making it one of the world’s busiest maritime corridors.
Key Figures & Groups
- Purbaya Yudhi Sadewa – Indonesia Finance Minister, initiator of the levy suggestion.
- President Prabowo Subianto – Indonesian president who has urged a more active role for Indonesia in global trade.
- Vivian Balakrishnan – Singapore’s Foreign Minister, vocal opponent of any tolls.
- Mohamad Hasan – Malaysia’s Foreign Minister, stresses the need for consensus among the three littoral states.
- Richard Marles – Australia’s Defence Minister, reaffirming commitment to UNCLOS.
- Sugiono – Indonesia’s Foreign Minister, later denied any plan to impose tariffs.
- Lowy Institute – Australian think-tank providing legal analysis of the proposal.
Data & Statistics
- The strait links the Indian Ocean with the Pacific and carries about 40 % of global seaborne trade (various sources).
- Iran’s Hormuz toll would affect roughly 25 % of the world’s oil shipments.
- Indonesia’s archipelagic waters total more than 3 million km² of EEZ, underscoring its reliance on maritime routes.
Why It Matters / Impact
A Malacca levy could generate significant revenue for the three littoral states, but it also risks establishing a precedent that challenges the principle of free navigation. Shipping companies warn that tolls could raise costs and reroute traffic, while legal scholars note potential violations of the United Nations Convention on the Law of the Sea (UNCLOS), which guarantees transit passage through international straits.
Official Statements & Responses
- Singapore reiterated that “the right of transit passage is guaranteed for everyone” and will not join any effort to impose tolls.
- Malaysia emphasized that any levy must involve “cooperation of all four countries” (Indonesia, Malaysia, Singapore, Thailand) and cannot be unilateral.
- Australia’s Defence Minister Marles stated that “freedom of navigation on the high seas is a fundamental principle contained in UNCLOS.”
- Indonesia’s Foreign Minister Sugiono later affirmed that Indonesia “will not impose tariffs on vessels transiting the Strait of Malacca,” citing UNCLOS obligations.
Criticism & Opposition
Legal analysts at the Lowy Institute argue that a levy would contravene Articles 38-44 of UNCLOS, which prohibit charges for mere passage. Australian Strategic Policy Institute commentator Euan Graham warned that monetising the strait could “set a worrying precedent” and undermine Indonesia’s own treaty-based sovereignty.
Conflicting Reports & Gaps
Sources differ on the seriousness of the proposal: some describe it as a “trial balloon” or off-hand remark, while others note that Indonesian officials have “walked back” the idea and denied any policy intent. No formal feasibility study has been published, and the positions of China and the United States on a potential Malacca levy remain unreported.

What’s Next

Indonesia is expected to conduct internal reviews of the proposal’s legal and economic implications, while monitoring developments in the Hormuz toll debate for potential spill-over effects.
