Indonesia Russian Oil Imports 2026: Why Jakarta Is Diversifying Crude Supply

On June 29, a tanker called the Sierra pulled into the Indonesian port of Balikpapan carrying just under 770,000 barrels of Russian crude oil, worth roughly $75 million. It sailed from Kozmino, Russia. It’s a small shipment in the scheme of global oil trade — but it marks the first delivery under a supply deal Jakarta struck with Moscow in April, and it captures something bigger about how the Iran war has reshuffled who buys oil from whom, according to Bloomberg reporting via gCaptain.

Why Indonesia needed a new supplier

Indonesia is Southeast Asia’s largest economy, and it’s a structural oil importer. Domestic crude production sits around 577,000 barrels a day, well below the government’s own 610,000 bpd target and a fraction of the roughly 1.5 million bpd the country pumped in the 1990s, according to OilPrice.com. Total petroleum demand, meanwhile, runs around 1.6 million bpd — far above what domestic refineries can process even at full tilt.

That gap became a crisis when the Strait of Hormuz effectively closed for weeks during the Iran war. Roughly 20–25% of Indonesia’s oil imports normally transit through the strait, and when that route seized up, Jakarta had to look elsewhere fast, per ICIS.

The economics of the pivot

President Prabowo Subianto’s April visit to Moscow produced a framework for up to 150 million barrels of Russian crude over time, according to Antara News. Rystad Energy analyst Prateek Panday told the Business Times that the diversification strategy is “backed by supply economics, refinery compatibility and medium-term energy security logic, not just opportunism around the Middle East crisis” — a framing Indonesian officials have echoed in public.

There’s a notable wrinkle in how the deal was executed: the June cargo was purchased not by Pertamina, the national oil company that normally handles energy imports, but by Lemigas, a government fuel-testing body, according to gCaptain. Indonesia’s energy ministry did not respond to requests for comment on the arrangement — a detail that has drawn scrutiny given the sanctions sensitivities around Russian crude purchases since 2022.

The cost of not diversifying fast enough

The bill for staying dependent on Middle Eastern supply during the crisis has been steep. Indonesia’s rupiah breached the psychological 18,000-per-dollar threshold in June, a record low, as Al Jazeera reported, with the country’s trade surplus narrowing from $3.3 billion to just $89 million in a single month as energy import costs surged and dollar supply tightened.

By May, that pressure tipped into an outright deficit. Indonesia Investments reported a $1.61 billion trade deficit for May 2026 — ending an unbroken six-year run of monthly surpluses stretching back to 2020. Fuel import costs alone jumped 99.5% year-on-year, and Pertamina had to prioritize domestic refinery supply over crude exports, pushing Indonesia’s own crude exports to zero during the worst of the Hormuz blockade.

What comes next

Jakarta’s exposure hasn’t fully resolved. S&P Dow Jones Indices has placed Indonesia on watch for a downgrade to frontier-market status, mirroring an earlier move by MSCI, according to Trading Economics — a signal that foreign investors are nervous about capital outflows even as oil prices have eased somewhat from their peak.

The Russia deal is unlikely to fully insulate Indonesia from future shocks; Russian crude flows have so far been sporadic, with only a handful of cargoes delivered over the past six months. But it does represent a structural shift in how Southeast Asia’s biggest economy is thinking about energy security — treating Russian supply not as a wartime workaround, but as a plank of a longer-term diversification strategy that could eventually extend to refinery and terminal investment through a stalled $24 billion Rosneft-Pertamina project in Tuban.
