U.S. authorities issued subpoenas to Goldman Sachs for documents related to the bank's dealings with troubled Malaysia state wealth fund 1MDB, The Wall Street Journal reported, citing a person familiar with the matter.
The WSJ reported that Goldman received requests for information earlier this year from the U.S. Department of Justice (DOJ) and the Securities and Exchange Commission, adding that Goldman was also providing information to the Monetary Authority of Singapore (MAS).
The WSJ said that the inquiries related to Goldman's role in bond sales it ran for 1Malaysia Development Berhad (1MDB).
Separately, Singapore's central bank said on Saturday it is examining the extent of Goldman's local unit's involvement in bond deals for 1MDB.
"MAS supervisory examination into the extent of Goldman Sachs (Singapore) Pte's involvement in the 1MDB bond deals is still ongoing," a MAS spokeswoman said in an email statement to Reuters.
The MAS has been questioning banks and financial institutions since last year as part of investigations into possible money laundering in the city state linked to 1MDB.
A Goldman Sachs' spokesman in Hong Kong declined to comment on the Singapore inquiry. 1MDB has said in the past it is not a party to the civil suit, does not have any assets in the United States of America, nor has it benefited from the various transactions described in the civil suit.
