Portugal’s central bank governor, Alvaro Santos Pereira, sold shares in two Lisbon-listed companies after a review by the European Central Bank raised questions under conduct rules for senior monetary officials.
The Bank of Portugal said the governor had bought shares in Galp, the Portuguese energy company, and Jeronimo Martins, the retail group, after taking office last year. The purchases were later reversed following discussions with the ECB, the central bank said. The divestment process has now been completed, though the Bank of Portugal did not say whether the transactions resulted in a gain or a loss.
Santos Pereira became governor of the Bank of Portugal in 2025 and, through that role, also joined the ECB’s Governing Council, the body responsible for eurozone monetary policy decisions. The case draws renewed attention to the financial restrictions that apply to top central bankers, particularly those with access to sensitive, market-moving information.
Disclosure Filed With The ECB
The investments were included in Santos Pereira’s declaration of interests submitted to the ECB in January, the Bank of Portugal said. The institution described the purchases as part of the governor’s management of his personal financial investment portfolio.
The matter became public after the Portuguese newspaper Publico reported that the purchases were made in December, roughly two months after Santos Pereira took up the governorship. The shares involved were in two prominent companies on the Portuguese stock market: Galp, one of the country’s major energy groups, and Jeronimo Martins, best known internationally for its food retail operations.
The central bank’s response indicates that the transactions were not hidden from the ECB, but were later judged to require corrective action. By unwinding the purchases, Santos Pereira brought his holdings into line with the standards applied to high-level officials within the eurozone central banking system.
Conduct Rules Limit Direct Equity Holdings
The ECB has tightened its ethics framework in recent years, with updated rules taking effect in January 2023. Under those rules, high-level ECB officials are restricted from buying shares in individual companies after entering office and are generally expected to place investments in broadly diversified collective investment vehicles, such as exchange-traded funds or mutual funds.
The aim is to reduce actual or perceived conflicts of interest. Central bankers participate in decisions on interest rates, bank liquidity, financial stability and crisis management, all of which can influence asset prices. Even when a personal investment is unrelated to a specific policy decision, direct share ownership can raise questions about impartiality and market sensitivity.
The ECB’s framework allows certain existing assets to remain as “legacy” holdings in some circumstances, but new purchases of individual equities after appointment are treated more strictly. The Bank of Portugal’s statement said Santos Pereira had increased his holdings, which meant the transactions were subject to review.
Case Highlights Governance Pressures
The episode comes at a time when public scrutiny of central bank governance remains high across Europe. Monetary authorities have spent recent years responding to inflation, slower economic growth, banking-sector risks, and volatile financial markets. Their decisions affect borrowing costs for households, companies, and governments, making the personal financial conduct of senior officials a recurring issue for institutional credibility.
For Portugal, the case is also politically sensitive because the Bank of Portugal plays a central role in national financial supervision while participating in eurozone-wide policy through the ECB. The governor’s position carries both domestic and European responsibilities, increasing the importance of compliance with cross-border ethics standards.
The Bank of Portugal did not indicate that the ECB had imposed a sanction, nor did it provide details on the size of the purchases. Its statement focused on disclosure, review and the completed sale of the shares. The absence of information about profit or loss leaves one part of the financial outcome unclear, but the main regulatory result is that the holdings were reversed after consultation with the ECB.
The case shows how the ECB’s post-2023 conduct rules are being applied in practice. It also underlines a broader expectation that senior monetary officials avoid direct exposure to individual companies while serving in roles that can influence financial conditions across the euro area.
