Portugal is providing €4.9bn in an emergency rescue to prevent the collapse of ailing bank Banco Espirito Santo, one of the country’s oldest and biggest financial institutions.
Bank of Portugal governor Carlos Costa said the money would come from a special fund set up during the eurozone’s recent crisis to help financial institutions in difficulty.
The move came after Banco Espirito Santo’s share price lost around 75% of its value last week.
The stocks crashed after the bank reported a record half-year loss of €3.58bn as previously unreported debts came to light after an audit.
The scandal involving the Espirito Santo family, one of Portugal’s best-known families, has gripped public attention.
The Portuguese bank’s hidden difficulties have spooked international markets, which fear the financial crisis that recently hit countries sharing the euro currency may not be over and more financial secrets remain to be discovered.
Mr Costa said authorities were compelled to step in to prevent contagion to the rest of the Portuguese financial system.
Banco Espirito Santo’s healthy businesses, including its retail arm, will be spun off and put in a new bank called Novo Banco, which will keep the bank’s current staff. Mr Costa said account holders’ money was safe.
The cash injection is a loan and will be repaid with interest, with no cost to taxpayers, he added.
The bank’s toxic assets, meanwhile, will remain at Banco Espirito Santo, which will become a so-called “bad bank”.
The Bank of Portugal, which regulates the country’s financial sector, has acknowledged it was wrong to trust the numbers provided in recent years by Banco Espirito Santo. Some Portuguese politicians are demanding an inquiry into why regulators and auditors failed to spot the bank’s problems.
Mr Costa, who did not take reporters’ questions after his televised late-night statement, said the bank broke financial rules and was guilty of mismanagement.
The bank is at the heart of the Espirito Santo family’s tourism-to-health care business empire on four continents.
The scandal erupted in May after an audit found accounting irregularities. Later, unreported debts at the bank emerged. The Espirito Santo family’s three main holding companies have in recent days requested bankruptcy protection.
Police suspect the bank’s former boss, Ricardo Espirito Santo Salgado, of fraud, forgery and money-laundering. He was questioned last week and released on three million euros’ (£2.3m) bail. He stepped down from his job last month.
The Espirito Santo family began its banking business in the 19th century. Before its recent problems, Banco Espirito Santo was the country’s largest private bank.
