Creditors suing Argentina over billions of dollars in defaulted bonds have subpoenaed HSBC Holdings Plc for information about the country's effort to raise money abroad, a person familiar with the matter said on Tuesday, as reported by Reuters.
US district judge Thomas Griesa has said he would wait for a decision on a pending appeal before ordering Citigroup to comply with a subpoena served by holdout investors seeking details of any threats from Argentina to process payments the court had blocked.
