HSBC and Morgan Stanley are among the potential creditors of companies whose shareholders and directors have been linked to the recent money-laundering bust.

More connections are surfacing as the authorities expand investigations into the associates of the 10 charged in an anti-money-laundering crackdown that has grown in value to S$1.8 billion.

Business filings of Singapore-incorporated companies linked to 24 persons, identified by the authorities as associates of the charged, show at least six banks as creditors to eight entities.
