SINGAPORE (Reuters) -HSBC on Wednesday said it is setting up a $1 billion growth fund called ASEAN Growth Fund that provides lending to companies that are scaling up via digital platforms across Southeast Asia. The London-headquartered bank is tapping into Southeast Asia's digital economy, which it said is among the world's fastest growing, expecting it to hit $600 billion in value by the end of the decade from $218 billion last year. "With a working population that is digitally native, increasing in size, and poised to consume more goods and services especially on e-commerce, ASEAN has so much potential for growth," said Amanda Murphy, HSBC's South and Southeast Asia head of commercial banking, at the launch of the fund.
