Iran Signals Clear Path for Pertamina Tankers Through Strait of Hormuz Amid Conflict
In a significant development for Indonesia's energy security, Iran has signaled it will allow Pertamina's oil tankers to safely traverse the Strait of Hormuz—a critical chokepoint now reopened after weeks of geopolitical tensions gripped global markets.
The Situation
The Foreign Ministry announced Saturday that Iranian authorities have given a "positive consideration" for the safe passage of Pertamina Group vessels through the Hormuz Strait, which had been effectively closed during peak hostilities between the U.S., Israel, and Iran.
Four Pertamina tankers were trapped in Middle Eastern waters when the Iran-U.S. conflict erupted on February 28, 2026. By mid-March, two vessels—PIS Rinjani and PIS Paragon—had already escaped the region. The remaining two are in the queue for safe passage.
"Based on coordination between the Foreign Ministry, Embassy in Tehran, Pertamina, and Iranian officials, Iran's Embassy has conveyed positive government consideration regarding the safe passage of Pertamina Group vessels through the Strait of Hormuz," said Foreign Ministry spokesperson Yvonne Mewengkang on Saturday.
Why This Matters for Indonesia
Energy Prices & Inflation Risk
Pertamina's operations are critical to Indonesia's energy supply chain. Any disruption to oil shipments can ripple through the domestic economy—raising fuel costs, transportation expenses, and ultimately consumer prices. The re-opening of this transit corridor signals potential relief from further energy shocks that had threatened to erode Indonesia's fiscal position during an already volatile period.
Rupiah Stability
Indonesia's currency had weakened as global oil prices surged more than 55% in March, the largest monthly gain since 1998. A stable corridor through Hormuz could anchor expectations that energy costs will normalize, supporting the rupiah and reducing inflation fears that had pressured Bank Indonesia's rate-holding policy.
Regional Trade Impact
The closure of Hormuz had prompted shipping companies to divert routes, adding weeks to delivery times and massive costs. For a trade-dependent economy like Indonesia, reopening this artery is crucial for IHSG-listed logistics companies like SAPX and for import-dependent sectors.
Technical Requirements Ahead
While Iran's signal is positive, the practical execution requires Pertamina to secure:
- Updated insurance protection for the vessels
- Crew readiness protocols
- Coordination with Iranian authorities for each transit
The Foreign Ministry said these technical preparations are underway and will determine the timing of the first vessel departure.
Market Reading
This news removes a tail risk from Indonesia's outlook—the possibility that energy costs would stay elevated indefinitely. Markets may already be pricing in some relief, having frontrun the broader Arabia-China oil-route normalization talks. However, any reversal in geopolitics could quickly reverse the gains.
For Pertamina directly, the news is unambiguously positive: it restores logistics flexibility and reduces reputational/financial strain from stranded vessels.
