The most-traded September iron ore contract on the Dalian Commodity Exchange ended up 2.3% at 895 yuan ($130.22) a tonne, edging closer to its record intraday high 911.5 yuan hit on July 3.
Tight supply conditions also supported iron ore prices, with imported stocks at China's ports hovering near the lowest level since early 2017. The port inventory fell to 115.35 million tonnes, as of July 12, from 115.6 million tonnes a week before, data compiled by SteelHome consultancy showed. <SH-TOT-IRONINV>
Demand for iron ore could pick up as steel mills' stocks have dwindled, said Darren Toh, steel and iron ore data scientist at Singapore-based Tivlon Technologies.
"Our data analytics model is sensing Chinese mills' iron ore inventory at warehouses dropping significantly over the last 10 weeks," he said.
This indicates that steel production in China remains brisk, despite output curbs in some of the country's steel hubs, amid "very strong" demand for the commodity for the country's infrastructure projects, Toh said.
China's daily crude steel output rose to record levels in June, according to Reuters calculations, even as anti-pollution restrictions pushed whole-month production slightly lower, official data showed on Monday.
Dalian coke futures climbed 2.8% to 2,167.50 yuan a tonne, after hitting 2,172.50 yuan a tonne earlier in the day, their highest in almost five weeks.
