HONG KONG, Aug 10 (Reuters) - Hong Kong's de-facto central bank bought HK$1.492 billion ($190.07 million) from the market in New York trading hours to stop the local currency weakening and breaking its peg to the U.S. dollar.
The Hong Kong dollar is pegged to a tight band of between 7.75 and 7.85 versus the U.S. dollar.
The aggregate balance - the key gauge of cash in the banking system - will decrease to HK$124.74 billion on Thursday, a spokeswoman for de-facto central bank HKMA said on Wednesday. ($1 = 7.8496 Hong Kong dollars) (Reporting by Donny Kwok; editing by Jonathan Oatis)
