Portuguese Banks Escape €225M in Cartel Fines as Lawsuit Looms Over Consumer Compensation

Portugal's parliament has erupted into a fresh battle over the nation's banking cartel scandal. The banking industry's lobby is defending lenders by invoking constitutional presumption of innocence — despite prior judicial findings of anticompetitive collusion that initially cost the sector €225M in penalties.

Those penalties have since been erased by statute of limitations. Meanwhile, separate class actions totaling €5.4 billion are now seeking direct compensation for borrowers allegedly harmed between 2002 and 2013.

Why This Matters

• €225M in fines vanished: 11 Portuguese banks escaped payment after courts ruled the competition case had expired due to procedural delays, not innocence.

• Consumer lawsuits pending: Separate class actions totaling €5.4 billion are now seeking direct compensation for borrowers allegedly harmed between 2002 and 2013.

• Legal loophole closed: A 2022 reform suspends prescription clocks during appeals, intended to prevent future cases from timing out.

Banking Association's Defense Draws Parliamentary Fire

Vítor Bento, president of the Portuguese Banking Association (APB), told the Budget and Finance Committee that because no higher court issued a final binding judgment, the cartel allegations remain legally unproven. He cited Article 32 of the Constitution, which guarantees presumption of innocence until conviction becomes definitive, and argued that administrative sanctions by the Autoridade da Concorrência (AdC) — Portugal's administrative competition authority — never achieved judicial finality.

"No harm to bank customers was demonstrated or even invoked. The case expired without conclusion because the administration and courts could not finish it within the legally prescribed deadline," Bento stated, emphasizing that spreads in Portugal tracked below the eurozone average during the decade in question.

That reasoning ignited backlash across the political spectrum. Socialist deputy Miguel Matos said Bento's invocation of innocence "should make you blush," noting that both the AdC and a first-instance tribunal had confirmed the infractions before the procedural clock ran out. "What happened makes us all cry with shame — that convicted parties do not pay fines for proven anticompetitive acts," Matos declared.

Chega party deputy Eduardo Teixeira compared the rhetorical tactic to former Prime Minister José Sócrates's strategy of framing prescription as exoneration in his own legal saga. "Coming here with the same rhetoric that a prescription is not a conviction does not befit a sector we all depend on," he said.

Bento fired back, suggesting that some lawmakers' reactions indicated they "disagree with the constitutional presumption of innocence itself." He argued that prescription exists not as a loophole but as a safeguard against unlimited state sanctioning power, and that the banking sector did not choose the outcome.

What the Competition Authority Actually Found

Nuno Cunha Rodrigues, president of the AdC, appeared before the same committee and expressed "perplexity" at the banks' attempt to "whitewash" conduct he said was judicially proven. He clarified that the penalty disappeared for "strictly procedural reasons," not because courts absolved the banks on merit.

Between 2002 and 2013, the 11 lenders exchanged strategic non-public data including future spreads, risk variables for credit approvals, and individualized monthly loan production figures. The Competition Tribunal ruled in September 2024 that this constituted collusion by object — a legal term meaning the practice was inherently anticompetitive regardless of whether specific customer harm could be proven — and violated both Portuguese and EU competition law.

"The exchange eliminated competitive uncertainty and facilitated alignment of commercial conduct in a concentrated market with high barriers to entry," Cunha Rodrigues explained. He rejected claims that the AdC delayed the process, noting that 22 months of the seven-year timeline fell under periods when evidence was judicially sealed or the case was suspended by interlocutory rulings later overturned by the Lisbon Court of Appeal.

The watchdog chief added that the case was paused or suspended for over six years of the 10.5-year prescription window due to factors beyond the agency's control, including parallel review by the Court of Justice of the European Union.

The Road to Prescription and Reform

After the AdC imposed sanctions, the banks appealed. The Lisbon Court of Appeal declared the case prescribed in February 2025, calculating that the maximum limitation period had expired in February 2024. The AdC and Public Prosecutor's Office sought relief from the Constitutional Court, which definitively rejected their second attempt in August 2025.

Under the old legal framework, Portugal's prescription regime counted time spent in appeal toward the expiry deadline. This created a perverse incentive: protracted judicial resistance could run out the clock. A 2022 amendment to the Competition Law now suspends the prescription period while decisions are under judicial review, designed to prevent repeat scenarios.

The AdC has asked for clarification that this rule applies retroactively to pending cases — a request rooted in the "cartel da banca" debacle.

The €5.4 Billion Question: Consumer Redress

While administrative fines evaporated, civil liability remains alive. The Ius Omnibus, a European consumer defense association, has filed five class actions in the Competition, Regulation and Supervision Court in Santarém, seeking compensation for all Portuguese residents who held home loans, consumer credit, or SME financing during the cartel period, as well as anyone who purchased goods or services from affected small businesses.

The association's economic experts calculated total damages at €5,368M through the end of 2022, arguing that coordinated rate-setting artificially inflated borrowing costs. The prescription of administrative penalties does not extinguish the right to civil indemnification, meaning customers can still recover losses even though the state cannot fine the banks.

Banks counter that no customer harm occurred. Some executives contend that competition during the period was "intense" and that spreads were among the lowest in Europe. The Santander Totta subsidiary said it "regretted" the prescription because it wanted the opportunity to prove in court that no anticompetitive harm materialized.

What This Means for Residents

For borrowers who may be eligible:

If you held a mortgage, consumer loan, or SME credit between 2002 and 2013, you are likely covered by the Ius Omnibus class actions. You do not need to opt in individually — the claim covers all eligible borrowers automatically. However, you should monitor the case proceedings to understand any required documentation.

To verify your eligibility, check whether your loan provider was among the 11 banks involved: Caixa Geral de Depósitos, BCP, Santander, BPI, Banco Montepio, BBVA, BES (now Novo Banco after 2014), BIC, Crédito Agrícola, or UCI.

Expected timeline: The Santarém tribunal is expected to issue initial rulings within 18 to 24 months from the date of this reporting. Compensation, if awarded, typically follows within 6-12 months of final judgment, though administrative appeals could extend this further.

Legal representation: The Ius Omnibus class action is funded through the European consumer protection framework, so individual borrowers do not typically incur legal fees unless they choose to hire separate counsel. For more information, contact the Ius Omnibus association through its official website or the Competition, Regulation and Supervision Court in Santarém.

For financial consumers broadly: The case underscores the gap between regulatory enforcement and judicial execution in Portugal. Even when infractions are confirmed, procedural complexity can shield wrongdoers from sanctions — though civil courts may ultimately deliver accountability.

For rule-of-law watchers: The controversy has reopened debate over whether prescription rules tilt too far toward defendants in white-collar cases. Left-wing parties, including the Communist Party (PCP), have labeled the outcome an "unacceptable scandal," while centrist lawmakers focus on ensuring the 2022 reforms are applied effectively going forward.

Political Fallout and Next Steps

Parliamentary deputies voted unanimously to request a formal Banco de Portugal opinion on the AdC conviction — a signal that lawmakers want to understand whether the central bank flagged or failed to act on the intelligence-sharing. Governor Mário Centeno is expected to testify in upcoming hearings.

The banks involved and their individual penalties were: Caixa Geral de Depósitos (€82M), BCP (€60M), Santander (€35.65M), BPI (€30M), Banco Montepio (€13M), BBVA (€2.5M), BES (€700K) — which collapsed in 2014 and was succeeded by Novo Banco — BIC (€500K), Crédito Agrícola (€350K), and UCI (€150K). The Barclays subsidiary that blew the whistle under a leniency program was spared sanctions from the outset.

Vítor Bento told lawmakers that the alleged conduct occurred "in a political, economic, cultural, and regulatory context that bears no resemblance to today," and that discussing commercial policy among member banks today would itself violate competition law. He presented data showing Portuguese mortgage rates consistently below eurozone averages throughout the disputed period.

Critics, however, argue that the rate comparison is misleading because it does not isolate what spreads would have been absent collusion. The AdC's case rested on conduct, not outcomes — the legal doctrine that certain agreements are so inherently harmful that proof of actual damage is unnecessary.

The episode has crystallized frustration with Portugal's slow-moving judicial system and raised uncomfortable questions about whether financial institutions enjoy de facto impunity when they can afford prolonged litigation. As one lawmaker put it: "The Republic itself is shamed when the powerful escape consequences simply by waiting out the clock."
