The HSBC headquarters is seen in the Canary Wharf financial district in east London Thomson Reuters HONG KONG (Reuters) - HSBC Holdings Plc said on Monday it had performed the world's first trade finance transaction using blockchain technology, a major step in boosting efficiency and reducing errors in the multi-trillion-dollar funding of international trade.

HSBC and Dutch bank ING successfully completed the transaction for food and agricultural group Cargill, the British lender said in a statement.

The use of blockchain technology in the banking industry is expected to reduce the risk of fraud in letters of credit and other transactions as well as cut down on the number of steps used.

Letters of credit are one of the most widely used ways of reducing risk between importers and exporters, helping guarantee more than $2 trillion worth of transactions, but the process creates a long paper trail and takes between five and 10 days to exchange documentation.

"At the moment, buyers and suppliers use a letter of credit, typically concluded by physically transferring paper documents, to underpin transactions," said Vivek Ramachandran, global head of innovation and growth at HSBC's commercial banking unit.

"What this means for businesses is that trade finance transactions have been made simpler, faster, more transparent and more secure."

Putting all of Asia Pacific's trade-related paperwork into electronic form could slash the time it takes to export goods by up to 44 percent and cut costs by up to 31 percent, the HSBC statement said, citing a study by the United Nations.
