Citigroup said last month it uncovered at least $400 million in bogus loans to Oceanografia at its Mexican subsidiary, Banamex.
Oceanografia had borrowed from Banamex using expected payments from Pemex as collateral.
Mexico's government has taken control of Oceanografia and begun a criminal investigation.
The FBI and the U.S. Securities and Exchange Commission are investigating the transactions, people familiar with the probes have said.
