China’s chief auditor discovered 94.4 billion yuan ($15.2 billion) of loans backed by falsified gold transactions, adding to signs of possible fraud in commodities financing deals.

Twenty-five bullion processors in China, the biggest producer and consumer of gold, made a combined profit of more than 900 million yuan from the loans, according to a report on the National Audit Office’s website.

“This is the first official confirmation of what many people have suspected for a long time -- that gold is widely used in Chinese commodity financing deals,” said Liu Xu, a senior analyst at Capital Futures Co. in Beijing. “Any scaling back by banks of gold-backed financing deals might lead to a short-term reduction in Chinese imports and also spur some sales by companies looking to repay lenders.”

As much as 1,000 metric tons of gold may have been used in lending and leasing deals in China, where commodities including metals and agricultural products are used to get credit amid lending restrictions, according to World Gold Council estimates.
