The Hong Kong dollar remained weak against a broadly firmer USD, despite a rebound in the stock market. The currency traded between 7.7552 and 7.7570, near Friday's low of 7.7585 in New York trade - its weakest since March 5. HK central bank said it was not worried about an outflow of capital, attributing outflows this month to repatriation of money raised in stock market listings and year-end demand by companies for USD.
