REUTERS/Bobby Yip/File Photo StanChart announced a $250 million share buyback and resumption of interim dividend payments worth 3 cents per share, or $94 million in total, joining other banks in rewarding shareholders after year-long regulatory curbs on payouts were removed last month. However, its income fell 5% thanks to low interest rates, which the bank said it hopes are bottoming out, and due to declining revenue in its cash cow transaction banking business.
