Pierre Mirabaud: CHF82 Million Bribery Scheme, Money Laundering Conviction and the Fall of a Swiss Banking Establishment Figure

For years, Pierre Mirabaud represented the respectable face of Swiss private banking.

A senior partner of one of Geneva's oldest private banks, president of the Swiss Bankers Association from 2003 to 2009 and a vocal defender of Swiss banking secrecy, Mirabaud regularly lectured foreign financial centres about regulation, tax policy, privacy and money laundering.

Then came an extraordinary reversal.

In September 2026, Switzerland's Federal Criminal Court convicted Pierre Mirabaud of bribing a foreign public official and aggravated money laundering.

The case involved almost 300 improper payments worth approximately CHF82.3 million to the head of Kuwait's state social-security institution in exchange for hundreds of millions of dollars in public pension assets being entrusted to Mirabaud-related investment business.

Pierre Mirabaud admitted the essential facts.

The court imposed a two-year suspended prison sentence.

He acknowledged that he had made a serious error of judgment, admitted personally earning approximately $1.8 million from the relationship, and had already participated in compensating the Kuwaiti pension institution with CHF42 million.

The case creates a devastating contrast between the public Pierre Mirabaud—defender of Swiss banking standards—and the conduct now established by a Swiss criminal court.

---

Who Is Pierre Mirabaud?

Pierre Mirabaud belonged to one of Geneva's most prestigious banking families.

He joined Mirabaud & Cie in the 1970s, became a partner in 1979 and senior partner in 1995.

His standing extended far beyond the family bank.

He chaired the Swiss Private Bankers Association from 1990 to 1993 and in September 2003 became president of the Swiss Bankers Association, effectively making him one of the principal public representatives of Switzerland's entire banking industry.

For six years, Pierre Mirabaud appeared in the media defending the reputation of Switzerland as an international financial centre.

He spoke about:

• banking secrecy;
• money laundering;
• regulatory standards;
• tax evasion;
• international financial competition;
• and the responsibilities of Swiss banks.

That public role is what makes the later criminal conviction so damaging.

Pierre Mirabaud Was Convicted — This Is No Longer Merely an Allegation

On 8 September 2026, Switzerland's Federal Criminal Court found Pierre Mirabaud guilty of:

bribery of foreign public officials

and

aggravated money laundering.

The court imposed:

two years' imprisonment, suspended,

with a two-year probationary period.

The proceeding was conducted under Switzerland's simplified procedure.

That matters because Mirabaud accepted the facts underlying the prosecution as part of the process.

The court then examined and approved the agreed criminal resolution.

The case number was:

SK.2026.25

The Swiss Federal Criminal Court's official schedule confirms the September 8 proceeding.

---

CHF82.3 Million in Improper Payments

The scale of the scheme was extraordinary.

According to the criminal case, Mirabaud arranged improper payments totalling approximately:

CHF82.3 MILLION

to Fahad Al-Rajaan, the former head of Kuwait's Public Institution for Social Security, or PIFSS.

PIFSS is not a private hedge fund or family office.

It is Kuwait's public social-security institution, responsible for assets intended to support pension and social-security obligations.

In exchange for the payments, Al-Rajaan directed substantial PIFSS assets toward the Geneva private-banking business and investments associated with Mirabaud.

The amount of Kuwaiti public money involved eventually reached approximately:

US$595 MILLION.

The payments continued for years.

---

Nearly 300 Payments Over Twelve Years

This was not a single questionable commission.

OCCRP reported that prosecutors established approximately 300 payments between 2000 and 2012.

The improper commissions totalled CHF82.3 million.

The duration matters.

The relationship continued for roughly twelve years.

And those dates create an extraordinary overlap with Pierre Mirabaud's public roles:

2000

The payment scheme begins.

2003

Pierre Mirabaud becomes president of the Swiss Bankers Association.

2003–2009

Mirabaud publicly represents Switzerland's banking industry.

2009

He retires as a partner of Mirabaud & Cie.

2010–June 2012

He continues working as an adviser.

2012

The payment period ends.

2026

Swiss criminal court convicts him.

That chronology is perhaps the most damaging fact of the entire affair.

For much of the period in which the illicit commissions were being paid, Pierre Mirabaud was publicly representing the Swiss banking industry.

---

Money Laundering: CHF77 Million and 122 Transfers

The case did not stop at bribery.

The Federal Criminal Court also convicted Pierre Mirabaud of aggravated money laundering.

According to reporting on the indictment and judgment, almost:

CHF77 million

was moved through approximately:

122 transfers

in ways designed to obscure the illicit origin and destination of the funds.

The Financial Times reported that the payments were routed through a structure involving intermediaries and offshore entities.

Pierre Mirabaud's conviction therefore concerned not only the payment of improper commissions but also the laundering of a large part of the proceeds.

---

An Offshore Structure Spanning the Bahamas, Canada and Switzerland

Swiss reporting described a complex payment mechanism.

According to the federal prosecution's case:

• a Bahamas-based company was involved;
• it maintained a bank account in Canada;
• funds passed through an intermediary account in Switzerland;
• payments were then transferred onward according to instructions from the Kuwaiti official;
• and offshore companies ultimately received the money.

The transactions were disguised through commission or retrocession agreements.

Swiss reporting said the structure was intended to conceal the nature of the payments.

For a banker who spent years presenting Switzerland as a financial centre with superior knowledge of its clients and high compliance standards, the contrast is severe.

---

Pierre Mirabaud Admitted the Essential Facts

This case is fundamentally different from many reputational scandals involving bankers.

There is no need to rely solely on hostile allegations.

Pierre Mirabaud admitted the relevant facts required by the simplified procedure.

During the hearing, he acknowledged that he had accepted the Kuwaiti official's proposal that the official personally receive commissions derived from the relationship.

Mirabaud told the court that he had made:

a "serious error of judgment."

He also said that he understood he had done something that should not have been done.

His lawyer subsequently emphasized that Mirabaud had cooperated fully with investigators and was accepting personal responsibility.

That cooperation deserves to be recorded.

It does not undo the conviction.

---

Mirabaud Personally Made Approximately $1.8 Million

One of the most striking moments during the proceedings concerned Pierre Mirabaud's own economic benefit.

When asked what he personally earned from the relationship, Mirabaud told the judge that the figure was approximately:

US$1.8 million.

Reporting from the court said the number appeared to surprise the judge, who asked for confirmation.

Mirabaud confirmed it.

This makes the affair more than an abstract corporate compliance failure.

The banker himself acknowledged a direct personal financial benefit arising from the broader relationship.

---

CHF42 Million Paid to the Kuwaiti Pension Institution

The financial consequences were also substantial.

Before the criminal judgment, PIFSS had received approximately:

CHF42 million

in compensation.

Swiss reporting connected this payment with the settlement of claims arising from the affair.

That amount is separate from the CHF82.3 million in improper payments.

The distinction is important:

• CHF82.3 million refers to the illicit commissions paid;
• CHF42 million refers to compensation provided to PIFSS.

---

Fahad Al-Rajaan: The Kuwaiti Official at the Centre of the Scheme

The recipient of the illicit payments was Fahad Al-Rajaan, who for decades headed Kuwait's public social-security institution.

Al-Rajaan later became the subject of major corruption proceedings in Kuwait.

Swiss reporting noted that he was convicted in Kuwait in connection with misuse of public funds and money laundering before his death in London in 2022.

That makes the Swiss case especially serious.

Pierre Mirabaud was not dealing with a minor private intermediary.

The illicit commissions were paid to the man controlling enormous pools of Kuwaiti public pension assets.

---

The Extraordinary Irony: Pierre Mirabaud Was Switzerland's Top Banking Lobbyist at the Same Time

Between 2003 and 2009, Pierre Mirabaud served as president of the Swiss Bankers Association.

He was effectively one of the industry's chief spokesmen.

During those years, he repeatedly defended Swiss banking secrecy and argued that Switzerland maintained high standards.

Yet the bribery arrangement established by the criminal case was continuing through exactly those years.

The contradiction is difficult to ignore.

The public spokesman promoted Swiss banking standards.

The private banker was participating in conduct that ultimately produced convictions for corruption and aggravated money laundering.

---

Pierre Mirabaud Once Called London a "Money-Laundering Paradise"

The historical record becomes almost surreal when Mirabaud's old statements are reread after his conviction.

In 2004, while president of the Swiss Bankers Association, Pierre Mirabaud attacked London's financial centre.

He described the City of London as a:

"money-laundering paradise"

and criticised British trust structures.

Mirabaud argued that Swiss banks knew their customers better than financial institutions elsewhere and said Swiss banking secrecy represented legitimate protection of client privacy.

At approximately the same time, according to the conduct later established in his own criminal case, millions of francs in improper commissions were moving in connection with the Kuwaiti relationship.

The historical irony could hardly be sharper.

---

He Defended Swiss Banking Secrecy Aggressively

Pierre Mirabaud became one of the industry's most forceful defenders of Swiss banking secrecy.

He argued that Switzerland had gone further than competing financial centres in identifying clients and combating illicit finance.

He criticised regulators for imposing rules too quickly and warned Switzerland not to exceed standards applied elsewhere.

At the time, these positions reflected mainstream Swiss banking-industry thinking.

Viewed after the 2026 conviction, however, they raise an uncomfortable question:

How credible was the industry's public certainty about compliance standards when one of its most prominent representatives was personally participating in a bribery arrangement involving foreign public money?

---

The Gestapo Remark

Pierre Mirabaud's public reputation had already attracted controversy long before the criminal case.

In February 2008, Germany was investigating large-scale tax evasion involving money hidden in Liechtenstein.

German intelligence authorities had obtained confidential client information.

Mirabaud reacted by comparing the German authorities' methods to those of the:

Gestapo.

The statement caused an immediate backlash.

The Swiss Bankers Association subsequently said Mirabaud regretted the impression created by the comparison.

The remark was widely considered an extraordinary rhetorical excess for the president of a national banking association.

---

The Remark Looks Even Worse in Retrospect

At the time, Mirabaud's anger concerned authorities aggressively pursuing financial secrecy and tax evasion.

His position was essentially that governments were going too far in obtaining confidential banking information.

Eighteen years later, Mirabaud himself would be convicted of foreign bribery and aggravated money laundering.

The two events are legally unrelated.

But reputationally the contrast is striking.

A banker who once compared aggressive financial investigators to Nazi secret police later stood before Switzerland's Federal Criminal Court admitting facts supporting his own corruption conviction.

---

Pierre Mirabaud Also Blamed Foreign Governments for Tax Evasion

During the European tax-evasion confrontation, Mirabaud said Swiss banks should not be turned into foreign tax police.

He argued that governments worried about citizens hiding wealth abroad should reconsider how heavily they taxed them.

"We are not a tax authority and we are not a police authority," he said in 2008.

Again, that position was part of the broader Swiss banking-secrecy debate.

It was not itself unlawful.

But after Mirabaud's criminal conviction, his confrontational defence of financial secrecy has become part of a much less flattering historical record.

---

A Striking Record of Bad Public Predictions

Mirabaud's public commentary also produced several embarrassing predictions.

In October 2008, amid the global financial crisis, Mirabaud reportedly insisted that no Swiss bank had required public funds and predicted such assistance would not be necessary.

Only days later, UBS required an unprecedented rescue structure involving the Swiss Confederation and Swiss National Bank.

Le Temps highlighted the spectacular timing when reviewing Mirabaud's tenure as banking-association president.

The newspaper also noted that he underestimated American pressure against Swiss banking secrecy shortly before the UBS tax confrontation exploded.

These were not crimes.

But they reinforced a reputation for overconfidence in defending the old Swiss banking model.

---

"The U.S. Department of Justice Extorted UBS"

When UBS eventually surrendered client information to U.S. authorities amid the American tax investigation, Mirabaud reacted furiously.

Le Temps quoted him as saying the American Department of Justice had effectively "extorted" UBS.

His tone reflected just how deeply Switzerland's banking establishment resisted the erosion of secrecy.

That rhetoric now belongs to an extraordinary historical contradiction:

the man defending banking confidentiality against foreign prosecutors was himself involved in a financial relationship that would eventually be prosecuted by Swiss authorities as corruption and money laundering.

---

Mirabaud Left the Swiss Bankers Association and the Family Bank in 2009

In June 2009, Pierre Mirabaud announced that he would leave the presidency of the Swiss Bankers Association.

He also announced that he would step down as a partner of Mirabaud & Cie by the end of that year.

He had been a partner since 1979.

The bank said the decision was personal and had been contemplated for some time.

Mirabaud continued as a consultant and maintained relationships with clients until June 2012.

That end date matters because the illicit commission arrangement identified in the criminal proceedings also continued into 2012.

---

The Criminal Investigation Emerges

The Kuwaiti affair eventually became known publicly as investigators examined the financial activities surrounding PIFSS.

Le Temps reported years before the conviction that Swiss federal prosecutors were examining allegations involving commissions paid in connection with Kuwait's social-security funds.

The broader Kuwaiti complaint alleged extremely large diversions from pension assets and complex international financial structures.

The Swiss investigation ultimately focused directly on Pierre Mirabaud.

By 2026 the case had moved beyond investigation and allegation.

There was an indictment.

An admission.

And then a conviction.

---

The Bank Itself Was Not Convicted in Pierre Mirabaud's Case

This point is essential for accuracy.

The September 2026 criminal conviction was against:

Pierre Mirabaud personally.

The Financial Times specifically reported that Mirabaud & Cie itself was not implicated as a criminal defendant in this proceeding.

The bank and individual should therefore not be casually conflated.

Pierre Mirabaud was a partner and later consultant of the bank during the relevant period, and Kuwaiti funds were placed with the institution and related investments.

But the conviction discussed here is his.

That distinction makes the article legally stronger.

---

Another Mirabaud Family Banker Was Also Sanctioned in the Affair

The fallout did not stop with Pierre.

Le Temps reported that Yves Mirabaud, another former senior partner and former chairman of the bank's anti-money-laundering committee, received a suspended financial penalty in connection with failures surrounding the improper payments.

The sanctions against other participants concerned their own conduct and legal responsibility.

They should not be merged with Pierre Mirabaud's conviction.

But their existence demonstrates how broadly the Kuwaiti affair affected the Geneva banking circle around the transactions.

---

From Voice of Swiss Banking to Convicted Banker

Few reputational reversals could be more dramatic.

Pierre Mirabaud once represented the Swiss banking establishment internationally.

He defended secrecy.

He attacked foreign financial centres.

He criticised investigators.

He complained about overregulation.

He argued that Swiss banks possessed superior knowledge of their customers.

He headed Switzerland's principal banking lobby.

And now the public record contains a Swiss criminal judgment convicting that same man of bribery and aggravated money laundering.

This is not a rival bank's accusation.

It is not an activist report.

It is not a sensational internet rumour.

It is a criminal judgment of Switzerland's Federal Criminal Court.

---

What Exactly Was Pierre Mirabaud Convicted Of?

The distinction between allegation and conviction matters.

As of September 2026, the public record establishes that Pierre Mirabaud was convicted of:

bribing foreign public officials;

and

aggravated money laundering.

The underlying conduct involved:

• improper commissions worth approximately CHF82.3 million;
• almost 300 payments;
• a senior Kuwaiti public official;
• Kuwaiti public pension funds;
• approximately US$595 million in business flowing toward Mirabaud-related banking and investment activity;
• extensive transfers used to obscure the flow of money;
• and a personal financial gain acknowledged by Mirabaud of approximately US$1.8 million.

---

What Should Not Be Exaggerated?

There is no need to exaggerate a record this serious.

Pierre Mirabaud received a suspended, not immediate custodial, prison sentence.

He cooperated with investigators.

He admitted responsibility.

Compensation was paid to PIFSS.

The family bank itself was not criminally convicted in his proceeding.

And the conviction does not mean every public position Pierre Mirabaud ever took concerning Swiss banking secrecy was inherently corrupt.

Those distinctions matter.

But they do not alter the central facts of the criminal judgment.

---

Why the Pierre Mirabaud Case Matters Beyond One Banker

The story is larger than Pierre Mirabaud.

For years Switzerland's private-banking establishment insisted that secrecy and discretion should not be confused with criminality.

That distinction is legitimate.

Many clients seek privacy for perfectly lawful reasons.

But banking secrecy can also create environments in which corrupt officials, opaque structures and improper payments become difficult to detect.

Pierre Mirabaud once publicly insisted that Switzerland knew its clients better than rival financial centres.

His own case now demonstrates why reputation and rhetoric are not substitutes for effective compliance.

---

A Devastating Symbol for Old Swiss Private Banking

Pierre Mirabaud belonged to the traditional world of Geneva private bankers:

family-owned institutions;

unlimited-liability partners;

personal client relationships;

discretion;

elite international connections;

and a strong belief in banking confidentiality.

He was one of that model's most prominent public defenders.

The CHF82.3 million Kuwaiti bribery affair now sits uncomfortably beside that legacy.

The man who spent years defending the honour and privacy of Swiss banking ended his public career with a conviction for corruption and aggravated money laundering.

That is why Pierre Mirabaud is no longer simply a historical figure from Switzerland's private-banking elite.

His story has become a case study in the distance that can exist between public reputation and private financial conduct.
