Apparently, it's on the back of the China commodity stories. First, this:
LONDON, July 8 (Reuters) - A cape cargo of high-ash, low volatile content Australian coal is being offered already on the water at $72.00 a tonne CIF South China after the Chinese buyer cancelled the contract, traders said.
"We heard rumours but we now know this cargo is absolutely real. We were offered it and checked the details of the shipment. All we know is the Chinese buyer walked away," one trader said.
This is the first confirmation of a Chinese coal buyer cancelling a contract, traders said.
There have been rumours for a week or so that Chinese buyers were trying to escape from contracts because of high stockpiles and slower end-user consumption in China.
Trader and producer coal suppliers in Australia and Russia have come to depend on Chinese demand to place their spot coal because demand in the Atlantic remains extremely depressed.
Also the 4 Rio Tinto employees detained by Chinese authorities doesn't help.
