BRASILIA, March 21 (Reuters) - Five Brazilian banks are joining British lender Standard Chartered Plc in seeking early repayment of loans to oil rig producer Sete Brasil Participações SA, which has been hit by a corruption scandal involving its main client Petrobras, the Estado de S.Paulo newspaper reported on Saturday.
The banks are seeking to trigger loan guarantees of 4.5 billion reais ($1.39 billion) to cut their losses on 12 million reais in loans extended to Sete Brasil, a company created to build rigs to tap Brazil's sub-salt offshore oil deposits, the paper said, citing unnamed banking sources.
Sete Brasil said on Friday that Standard Chartered made a formal request to Fundo Garantidor da Construção Naval, or FGCN, to trigger guarantees on a loan. FGCN, which provides protection to banks from potential defaults by shipbuilding firms, has 30 business days to study the request, Sete said in a statement.
The Brazilian banks, Banco Bradesco SA, Banco do Brasil SA, Caixa Economica Federal, Itaú Unibanco Holding SA and Banco Santander Brasil SA , had to follow Standard Chartered's lead to get an equal share of the guarantees, Estado reported.
The move aims to put pressure on Brazil's National Development Bank (BNDES) to release long-term financing that has been frozen for years. The situation worsened in recent months when Sete was implicated in the kickback scandal at Petroleo Brasileiro SA, its main client, by a former executive.
Efforts to contact Sete and the banks for comment on the Estado report were unsuccessful.
The corruption scandal led Petrobras to consider cancelling its orders for seven rigs and cut off Sete's access to fresh financing. Sete is 2.5 billion reais in arrears on payments to contractors, the newspaper report said.
Sete's main creditor is Banco do Brasil with loans worth 3 billion reais, while Bradesco, Itaú BBA and Santander each lent more than 2 billion reais and Caixa 1.5 billion, the newspaper said, citing a Sete shareholder. Standard Chartered is the smallest creditor, with a $250 million loan, it said.
The Standard Chartered loan was one of many deals in which foreign banks helped fund Sete Brasil's plans to build 29 rigs.
The Rio de Janeiro-based Sete Brasil faces 11 billion reais in debt repayments next month and creditors are reluctant to roll over its debt.
State lenders BNDES and Banco do Brasil SA have been in talks to disburse more than 4 billion reais in bridge loans to Sete Brasil. But the lifesaving loan could fall through after former Sete executive Pedro Barusco admitted accepting bribes in exchange for contracts.
