Newcastle Coal Sits at $124 as Indonesia Export Rules and Chinese Mine Accident Keep Supply Squeezed
Indonesian export delays and a deadly Chinese mine accident are squeezing Newcastle coal supply, sustaining pressure after the benchmark hit nearly two-year highs in June.
Newcastle coal physical stood at $124.55 a tonne as of Sunday (2026-08-23), still below the $148.75-a-tonne peak hit in early June (2026-06-08) but supported by supply disruptions on two fronts that show little sign of resolution. Indonesia's new export rules had caused shipping delays that directly tightened the spot market, driving that surge just as Asian summer power demand was building, The Star reported.4
But the supply side has since been compounded. A deadly mining accident in China's biggest coal-producing region has reduced available tonnage from a second front, Mining.com reported, with analysts and industry officials warning the combination of Chinese output losses and Indonesian export chaos could sustain elevated prices well into the second half of the year.5
Running beneath both supply shocks is a demand shift that is reshaping Asian power generation. The Iran war disrupted approximately 20% of global LNG flows after the closure of the Strait of Hormuz and attacks on Qatar's largest export facility. Qatar's Ras Laffan plant triggered force majeure, removing close to 10.2 million tonnes per annum of LNG supply to Asia, with the partial shutdown expected to run through late summer, Rystad Energy said.3,4
Japan and South Korea moved quickly to cover the gap with coal. Japan's coal-fired power output rose 11.1% in April 2026, the fastest pace in at least a year, while gas-fired generation fell 12.9% to 16,447 gigawatt-hours, Reuters reported. South Korea's numbers were more dramatic: coal-based electricity climbed 39.7% year-on-year to 10,733 gigawatt-hours in April 2026, the largest increase since August 2019, while gas output fell 6.4%, Korea Power Exchange data showed.2,1
The switching spread further. Vietnam's coal-fired electricity production rose 12.3% to a record 17,864 gigawatt-hours in April 2026. DBX Commodities estimated Asian thermal coal imports in May 2026, excluding China and India, rose 9.4% to 31 million metric tons.1
Price signals help explain the pace. Asian spot LNG prices rose 62% from the start of the Iran conflict against a 13% gain for the Newcastle coal benchmark, Reuters reported. JKM Asian LNG stood at $22.94/MMBtu on Sunday (2026-08-23), near three-year highs Rystad Energy had previously flagged, continuing to make coal the more economic fuel for utilities with dual-fuel capacity.2,3
Rystad Energy projects an additional 150 million tonnes of cumulative Asia-Pacific thermal coal consumption through 2030, with roughly half expected in the near term. That demand pull is a supply gap, Rystad said, not a policy reversal — LNG cannot be easily substituted at current prices given existing infrastructure constraints.3
"The longer this war continues, the more shifts we will see," said Andre Lambine, electricity analyst at S&P Global Energy, quoted by Kyodo. The Ras Laffan partial shutdown is still running, and Indonesia's export regime remains unsettled.1
The near-term test for the bull case is twofold. A fresh deterioration in Indonesian shipment flows, or further setbacks to Chinese mine production, would put the June (2026-06-08) highs back in play for ICE Newcastle coal front-month contracts. Stabilisation on either front would leave the market to prove whether Japanese, South Korean and Vietnamese coal demand is durable enough to hold prices near current levels without a continued supply squeeze driving them there.5,4,3
