HONG KONG, April 15 (Reuters) - Hong Kong's de-facto central bank bought HK$903 million ($115.05 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$56.261 billion on April 18, an HKMA spokesperson said on Saturday morning. ($1 = 7.8486 Hong Kong dollars) (Reporting by Donny Kwok; Editing by Sandra Maler)
