ANTI-MONEY LAUNDERING AND ANGOLA: THE CASE OF THE FROZEN $900 MILLION IN SWITZERLAND


An academic and journalistic-style photograph set in a library or study office, showing a researcher's desk focused on the Carlos São Vicente money laundering case. In the foreground, a person's hands are visible: one hand rests on a document titled "SYSTEMIC FAILURES IN ANGOLA’S ANTI-MONEY LAUNDERING FRAMEWORK," while the other holds a magnifying glass over the text. The desk is cluttered with open academic books and legal papers. In the center, a laptop displays a news article with the headline: "THE ANGLO-SWISS $900 MILLION PUZZLE: CARLOS SÃO VICENTE CASE EXPOSES GLOBAL AML GAPS." In the blurred background, a projector screen shows a world map with Angola and Switzerland highlighted, and bookshelves filled with volumes line the walls, emphasizing a scholarly investigation into international finance and regulatory oversight.

1. Introduction

         This contribution aims to explore the failures of the Angolan Anti-Money Laundering Counter-Terrorism Financing (AML-CFT) legal frameworks in addressing the problem of illicit money flows in light of a prominent case involving the “AAA” Insurance Company and its former CEO. Such a case, which was widely reported in the national and international press, shocked Angola after Swiss authorities, in November 2022, seized $900 million deposited in the CEO bank accounts at the SYZ Bank SA, in Geneva. This case assumes particular significance as it seems to be the story of a “collective failure” by multiple authorities and financial institutions in preventing money laundering and explains partly why the country was kept in the FATF Grey list in October 2025. Building on an analysis of this case, this paper will illustrate the shortcomings in Angola’s money laundering prevention system, despite substantial progress in recent years, and the role of Switzerland in such a context. The reflection will focus on the missing role of the banking systems and regulatory authorities in preventing transnational money laundering.

2. A Multi-Million-Dollar Angolan Case of Financial Crime: An Example of Multi-Jurisdictional AML Failures?

 

The case of the former Angolan Businessman Carlos São Vicente[1] is illustrative of the weak AML-CTF controls in the country. The facts are the following: Carlos São Vicente was the CEO of the insurance company AAA, which got a near monopoly on the insurance market for the oil and gas industry[2]. The Company was established by Sonangol, the national oil and gas company (NOC), but gradually Carlos São Vicente was able to be a majority shareholder. The case was known to the public when Carlos São Vicente transferred an amount of $900 million to the Swiss Bank SYZ, SA through several bank accounts.

The bank notified the Swiss authorities, and this led to an investigation by the Public Prosecutors in the Canton of Geneva in 2018, which initiated a procedure against Money Laundering, it was the appeal challenging the public prosecutors made by Carlos São Vicente that led to court proceedings. The ruling of the Court of Geneva was to freeze the money[3] and it was during these proceedings of this case that the Angolan authorities were alerted. In 2021 Switzerland partially reversed the freeze[4].

After the alert made by Swiss Authorities, the Angolan authorities started an investigation and initiated criminal proceedings against Carlos São Vicente and he was ultimately judged and convicted for 9 years for three offences (i.e., embezzlement, money laundering, and tax fraud) and ordered to pay $500 million in damages by the second instance Court[5]. The Supreme Court confirmed the decision and ordered the compensation of damages for $4,5 billion. The Angolan Constitutional Court also denied an appeal[6]. Furthermore, the Angolan Court froze and seized all the assets which belonged to Carlos São Vicente in Angola[7]. Carlos São Vicente after these losses in court also made a complaint to the African Commission on Human Rights and the UN Working Group on Arbitrary Detention[8].

More recently, it was found that Carlos São Vicente also deposited in a Singaporean Bank more than $558 million USD[9] and those funds were also frozen in a decision by the High Court in Singapore. The measure adopted against the former CEO further amplified the complexity and the international nature of this case[10]. Moreover, other bank accounts in the name or in benefit of Carlos São Vicente were also found in Bermudas and in Portugal, which were frozen at the request of the Angolan authorities[11]. Some of these accounts were associated with Carlos São Vicente family members and known associates, as well[12].

 

3. Who, why, and how: Exploring AML-CFT Challenges

 

The first question that emerges in such a relevant case is related to the failure by the Financial Regulatory Authorities in Angola, particularly the Central Bank[13] and the Insurance Regulatory Authority[14], to detect such a significant case of money laundering. Another relevant question pertains to Governance, Risk and Compliance (GRC) and Corporate Governance in the Insurance Company “AAA” headed by Carlos São Vicente[15], although it will be not explored in this article.

From a regulatory perspective, Angola has fully incorporated in its domestic law the Forty (40) Recommendations of the Financial Action Task Force (FATF) regarding AML-CTF. More precisely, it adopted the FATF recommendations in 2011 in the Anti-Money Laundering Law and Combating the Financing of Terrorism (AML-CTF) Statute nº 34/11 of 12th of December[16], and this was followed by the adoption in 2020 of a new AML-CTF Statute with more comprehensive rules[17]. Additionally, Angola adopted a regime on the crimes of money laundering and related offences[18]. Such a jurisdiction is also regularly evaluated by the Financial Action Task Force by the Eastern and Southern Africa Anti-Money Laundering Group (ESAAMLG)[19], the latest evaluation was on June 2023[20]. The Angolan Financial Intelligence Unit[21] is also quite important in the Angolan AML-CFT system.

Based on the analysis of such cases, it appears that ex-ante controls were not put effectively in place and the relevant regulatory authorities failed in their basic function of proper auditing and regulating a company with a virtual monopoly on the insurance market in the oil and gas industry. Moreover, it appears that Angolan banks, which were involved in the different transactions for the transfer of money abroad, failed to comply with the basic rules of their compliance programmes, even though the Central Bank and the Insurance Regulatory Authority have adopted strong guidelines on Anti-Money Laundering, which are mandatory for those institutions.

The second question is about the role of the Singaporean and the Swiss banking sector in this case, how Carlos São Vicente was able to deposit hundreds of millions of US Dollars in personal accounts in his name or controlled by him and, why those banks were not able to raise alerts in their internal compliance programs, particularly considering that he was politically exposed (he can be classified as a PEP[22]). More precisely, how can a PEP deposit almost 1 billion USD dollars without raising suspicions in a Swiss Bank?

One of the lines of defence failed in this case, apparently[23]. To this end, it must be highlighted that, by looking to AML rules, Angola is still a country that has weaker controls (even though it has fully adopted the FATF Recommendations) than Switzerland or Singapore. Thus, enhanced due diligence is needed when a bank has a customer which originates from a riskier jurisdiction. In other words, the responsibility to implement measures also needs to be put on countries that score highly (often developed countries) on the AML Index. Otherwise, the lack of measures helps to facilitate illegal capital flight from Africa[24], and this risk needs to be managed better by the financial institutions of the developed countries. Despite these countries froze the funds they should have better implement controls ex ante in KYC (“Know your Customer”) in the sense that a basic due diligence would reveal some risks in the personal deposits of Carlos São Vicente banks accounts at the SYZ Bank[25].

The Swiss Financial Market Supervisory Authority (FINMA) issued a public rebuke of the weak controls at SYZ Bank, the reprimand is on the website of FINMA, whereby the Regulator states that the Bank was found to be in breach in its duty of due diligence, even though it abided by its duty to report the funds, but no fine or penalty was imposed[26].

Currently the money is frozen is Switzerland, which suspended judicial cooperation with Angola[27] citing conditions of the detention of Carlos São Vicente. This raises the issue of judicial independence in Angola and the integrity of its legal system and the needed guarantees of proper due process of Law in Criminal matters, which even though is guaranteed formally by the Angolan Constitution and its Code of Penal Procedure, however Swiss authorities are not fully satisfied that this is the case.

Without these guarantees, judicial international cooperation is not possible, particularly in this case and in the future important cooperation might be on hold between Angola and Switzerland[28].

This takes us to the discussion of Asset Recovery in general, especially important in the crimes of corruption, if countries are not able to cooperate, this means that the stolen assets might not be returned to the country and this further endangers the possibility of fighting crimes such as corruption and recover their proceeds,  the United Nations Convention Against Corruption (or Merida Convention), which sets out the global emerging norm against Corruption and which both Angola and Switzerland have ratified explicitly enshrines the principle that the proceeds of corruption need to be recovered and repatriated to the country where they were taken[29].

 

Conclusion

AML regulation needs to be based on risk management and should not be mere “tick the box” exercise of following formal procedures, it should be a risk based approach. It is necessary to instil a culture of compliance of AML-CTF in the organizational environment of legal entities, particularly in the financial and banking sector. Thus, regulatory authorities need to foster and incentivize changes in the organizational cultures of banks, both in Angola as a developing country and Switzerland or Singapore as developed countries.

The analysis of this case also demonstrates that the main predicate crime alleged was embezzlement, a significant threat for sustainable development in the continent and in Angola. Despite the country making some rapid progress in the last five years, it is still possible to identify failures in the Angolan financial institutions and the Regulatory Financial Authorities, which failed to properly audit, inspect and regulate the company and its board.

The issue at hand is the inconsistency of enforcement actions in Angola. There have been numerous instances of potential and suspected corruption (broadly defined)[30], as well as money laundering, that have not received equal attention or been pursued with the same vigour as the case in question. This disparity highlights the pressing need for more transparent practices within the extractive sector. For instance, Company AAA was established with a de facto monopoly over the oil and gas industry's insurance sector. Such concentration of power underscores the significance of stringent disclosure regulations. It is imperative that we delve deeper into this matter through future research to better understand and address these concerns.

The Basel Institute on Governance has a very interesting tool which ranks countries according to the risks posed by Money Laundering, the AML Index[31] and Angola is not well positioned. This Index gives us an idea of the risk posed by different jurisdictions. This is important, considering the complexity if this case and the fact that involves multiple jurisdictions[32] this case exemplifies the need for continuous training on AML-CTF of financial intermediaries (banking and insurance employees for instance) and others (such as Lawyers or Accountants) in Angola and public officials, such as Prosecutors[33] , the Criminal Investigation Police[34] and the Tax Authority[35].

International cooperation is of paramount importance, and we have seen the issues which arise when courts in Switzerland raised the concern of the due process of Law and the overall integrity of the judicial system of Angola. Hence, the country needs to strengthen its judicial system and effectively guarantee the independence of courts to effectively fight corruption, and this not always the case.

On the other hand, a valid criticism we can make about developed countries is that their regulatory authorities sometimes are too lenient towards banks. For instance, the Bank SYZ SA was not even fined for its failures in the area of due diligence, even though FINMA had ruled against it. This forms or inertia or leniency needs to change, otherwise economic crimes will not be prevented or punished[36].

Corruption as a predicate crime is quite important in the analysis of this case. Thus, the importance of fighting corruption and although the country has made some significant efforts and increased its position in the 2022 Corruption Perceptions Index, it is now ranked 121 out of 180 countries in [37] and as a comparison the country in 2017 was ranked 167 out of 180 countries. Thus, the country has improved significantly in the last 8 years in terms of fighting and preventing corruption, however this is still not enough, as the benchmark for Angola should be the more advanced countries in SADC such as Botswana or South Africa. Reputation is a key factor for African countries and Angola and a country with a low risk of money laundering will improve its business environment and will attract more capital.

Angola also needs to consider the full adoption and implementation of a specialized body or agency in against corruption and financial crimes, as enshrined in the United Nation Convention Against Corruption[38], the adoption of Deferred Prosecution Agreements (DPAs) would also help, as the fight against this type of crime requires new tools, not currently available for prosecutors and judges in the country. In conjunction with the Financial Intelligence Unit, this will further increase the attractiveness of the country and reduce its risk factor.

Considering what was explored above, it is not accidental that Angola was added to the Grey list of the Financial Action Task Force in October 24th of 2024, and kept in the list a year later, because of its risk profile and the fact that it did not correct the deficiencies in the mutual evaluation report.  In the decision of October 2025, the FATF specifically points out to the need to Angola to work on specific issues, particularly the need to improve its risk-based supervision overall, in special the risks of non-banking entities and designated non-financial businesses and professions, the need to have proper beneficial ownership information, the need to increase money laundering investigations and prosecutions and the need to implement an effective process of targeted financial sanctions[39].

This case also illustrates that AML-CFT systems can help in the fight against corruption[40], although there are now interesting mechanisms such as the new ISO 37001 Management System Against Bribery[41] which can be used both by the private sector and the public sector in the fight against corruption[42]. This means a shift towards prevention and an ex-ante system of controls, instead of an ex-post system of control, when the crime already happened and the proceeds of the crime are laundered, this is a paradigm shift which requires legal risk management, and this is the new path for the fight against Corruption and Money Laundering in the continent and in Angola in particular.
