Commodities trader Mercuria Energy Group Ltd. struck a deal last summer to buy $36 million of copper from a Turkish supplier. But when the cargoes started arriving in China, all it found were containers full of painted rocks.
The saga unfolds like a gangland thriller, with the Swiss trading house saying it’s been the victim of cargo fraud. Before its journey from a port near Istanbul to China even began, about 6,000 tons of blister copper in more than 300 containers were switched with jagged paving stones, spray-painted to resemble the semi-refined metal.
The bizarre case highlights commodity traders’ vulnerability to fraud, even when security and inspection controls are in place. In 2014 and 2015, Mercuria took provisions to cover potential losses after metal contained in a warehouse in the Chinese port of Qingdao was seized by authorities as part of fraud investigation
