Steelmakers and miners were keen to agree before Christmas on a price for the period between January 1 and March 31, and they have agreed that premium hard coking coal sold under the contract will be priced at $US285 per tonne during the period.
The price was agreed by Glencore (which produces coking coal at the Newlands and Oaky Creek mines in Queensland) and Nippon Steel earlier this week, and matches the price set in the December quarter of 2011.
Miners working under the contract have been receiving $US200 per tonne for their coal since October 1, and they were receiving just $US81 per tonne under the contract price as recently as the first quarter of 2016.
Prices for both coking and thermal coal have rallied strongly since the start of 2016, after China ordered its coal mines to produce less as part of efforts to reform the sector.
Those production cuts combined with supply interruptions in Australia to ensure tight supply for coking coal in particular between June and November.
The highest quarterly contract price ever agreed was in the June quarter of 2011, when miners were paid $US330 for each tonne of coking coal amid supply shortages caused by floods in Queensland.
Glencore and Anglo American both sell their Queensland coking coal under the traditional quarterly contract system, but some like BHP Billiton and Mitsubishi prefer to sell their product at the daily market or "spot" price.
The spot price rallied from $US75 per tonne in February to $US308.80 per tonne in November, by which time BHP was making profit margins of more than $US230 on each tonne of coal sold.
The near-term trajectory of the spot price will likely depend on whether the cyclone season in Queensland causes any disruptions to supply.
