But Brazil’s economic fortunes eventually turned and, plagued by scandals, Mr. da Silva’s leftist Workers’ Party lost the presidency last year when the Senate impeached his handpicked successor, Dilma Rousseff, in a power struggle that consumed the nation.
Mr. da Silva, 71, who has called the charges against him a “farce,” has been planning a political comeback. Despite multiple corruption allegations against him, he has announced his intention to run for president in next year’s election and has been widely considered a leading contender.
Now the ruling could deliver a crippling blow to his aspirations.
Judge Sergio Moro, who issued Wednesday’s verdict, said that under Brazilian law, Mr. da Silva would be ineligible to run for office for twice as long as his sentence, or 19 years.
Legal scholars interpreted the ruling to mean that Mr. da Silva could still run for president while the case is being appealed. But if he fails on appeal, they said, it could either leave the Workers’ Party without an obvious candidate in next year’s vote or prevent him from taking office.
The conviction is the latest salvo by Brazil’s judicial branch, which has declared war on the country’s entrenched culture of corruption. Brazil’s current president, Michel Temer, was charged last month with corruption, part of a near constant stream of allegations and charges that have ripped through the nation’s political establishment in recent years.

Judge Moro, who oversees cases stemming from a broad graft scandal surrounding the state-controlled oil company, said Mr. da Silva’s actions were part of a “scheme of systemic corruption” in Petrobras.
“The president of the republic has enormous responsibilities,” Judge Moro wrote. “As such, his culpability is also” enormous when he commits crimes, he added.
Mr. da Silva presided over a period of robust economic growth in Brazil and remains a widely popular figure, credited with leading a social transformation that lifted millions from poverty in a nation with one of the world’s biggest disparities between rich and poor.

Despite the corruption allegations against him and his party, Mr. da Silva has been leading in recent public opinion polls on the election. Mr. Moro, the judge who convicted him, is often cited as Mr. da Silva’s closest rival in hypothetical matchups in the presidential race, though Mr. Moro has ruled out running for office.
In the verdict, Mr. Moro said that the former president had sought to intimidate the court, which the judge argued could be grounds for ordering his immediate arrest. Yet, Mr. Moro wrote, he deemed it “prudent” to allow Mr. da Silva to remain free pending an appeal.
Sending a former president to jail would be a “traumatic” event, he wrote.
While Mr. da Silva’s conviction involves relatively modest sums, especially compared with the staggering scale of some corruption cases in Brazil, prosecutors have described him as the mastermind of an enormous kickback scheme that enabled his party to buy support in Congress.
The case against him began with a probe into money laundering at a gas station. But as prosecutors continued digging, they said they discovered billions of dollars worth of bribes involving Petrobras and powerful contractors like Odebrecht, a large construction company with deep ties across the hemisphere. The case — which became known as the Lava Jato, or Car Wash, scandal — has ensnared other powerful politicians and put dozens of lawmakers under a cloud of suspicion.
Eduardo Cunha, the former speaker of the House, was sentenced in March to 15 years in jail for money laundering and corruption uncovered during the Petrobras investigation. And Mr. Temer, the current president, is working furiously to avoid being put on trial, hoping to convince lawmakers not to send the charges against him to the Supreme Court, the only venue where senior sitting politicians can be prosecuted.
The investigations have left Brazilians with few prominent politicians untainted by allegations of corruption. Wary politicians, meanwhile, have been considering passing an amnesty law to shield themselves, arguing that such protection is warranted to avert a collapse of the political system.
