Bank Negara Malaysia, the country's central bank, has cancelled the 20-day interest-fee period for credit card holders who fail to replay their outstanding balances from the previous month, the bank tells CardLine Global. The rule took effect this week. Credit card holders who make partial or minimum payment for their outstanding balances will be charged interest for all new retail transactions in the following month. Credit card balances in Malaysia stood at 21.1 billion ringgits (US$6.4 billion or 4.1 billion euros) in May, up 1.9% from 20.7 billion ringgits in April, the bank says. Overdue balances stood at 52.8 million ringgits in May, up 4.8% from 50.4 million ringgits in April.
