China's coking coal auction market had 148.85 Kt (mainly primary coking coal and raw blending coal) listed on Dec 19, and the unsold rate dived 20 pps DoD to 3%. The average closing premium for all sold lots was 9.67 yuan/t. Coke makers gradually began moderate restocking due to low inventories, improving coking coal transactions and reducing the auction failures. Most sold lots saw marginal increases of 3-15 yuan/t in settlements compared to previous levels.
