The Swiss Banking Triangle: How Epstein Brokered a Secret Merger Between Two of Europe's Oldest Banks

In the fall of 2015, two of Europe's oldest private banks were in confidential discussions about a merger. Julius Baer, founded in 1890 and headquartered on Zurich's Bahnhofstrasse, managed roughly 400 billion Swiss francs in assets. Edmond de Rothschild, part of the banking dynasty that had financed European governments since the Napoleonic Wars, managed approximately 170 billion Swiss francs from Geneva. A combination of the two would have created a private banking powerhouse controlling more than half a trillion francs.

The intermediary who brought the two sides together was Jeffrey Epstein.

The Merger Talks

Boris Collardi became CEO of Julius Baer in 2012 at the age of 37, making him the youngest chief executive in the bank's history. Under his leadership, Julius Baer aggressively expanded its client base, particularly in emerging markets and among ultra-high-net-worth individuals. Collardi's strategy relied on personal relationships with wealthy clients and the intermediaries who connected them.

Epstein was one of those intermediaries. Documents obtained by the Swiss financial publication Inside Paradeplatz show that Epstein facilitated introductions between Collardi and Ariane de Rothschild, who had taken over management of the Edmond de Rothschild group after her husband Benjamin's death. The merger discussions were conducted in strict secrecy. Neither bank disclosed the talks publicly, and the negotiations ultimately collapsed without a deal.

The failure of the merger does not diminish the significance of Epstein's role. A convicted sex offender who had served prison time in Florida was operating as a power broker between two of the most prestigious financial institutions in Europe. The question is how he maintained that access, and what the banks understood about the man they were dealing with.

The $25 Million Contract

In October 2015, the same period as the merger discussions, Ariane de Rothschild signed a $25 million contract with Epstein's Southern Trust Company. The contract's stated purpose was "risk analysis and the application and use of certain algorithms."

Southern Trust was not a technology company. It was a legal entity Epstein used for various financial operations, including funding Carbyne, the Israeli surveillance technology startup in which former Israeli Prime Minister Ehud Barak held a significant stake. Barak's involvement with Carbyne had been facilitated by Epstein, who arranged Barak's participation in the 2014 Herzliya Conference, sponsored by the Rothschild Caesarea Foundation.

The $25 million figure is large for an algorithm licensing agreement, particularly one involving a company with no public track record in financial technology. The contract's description is vague enough to cover almost any transfer of funds. "Risk analysis" could mean portfolio stress testing, or it could mean something else entirely. "Certain algorithms" is not a term of art in financial technology. It is a placeholder that avoids specificity.

On February 25, 2026, Bloomberg reported that the Edmond de Rothschild board had initiated an internal review of Ariane de Rothschild's financial relationship with Epstein. The review is ongoing.

UBS and Maxwell

The Swiss banking connections extend beyond the merger talks. After Ghislaine Maxwell's arrest on July 2, 2020, UBS moved approximately $19 million on her behalf. The transfers occurred while Maxwell was in federal custody, suggesting either pre-arranged instructions or active management of her accounts by bank representatives acting with existing authorization.

UBS has not publicly commented on the Maxwell transfers. The bank has maintained that it complies with all applicable sanctions and regulatory requirements. Swiss banking secrecy laws, while weakened by international pressure over the past two decades, still provide significant protection against public disclosure of client transactions.

The Pattern

Epstein's Swiss banking relationships followed a consistent pattern. He positioned himself as a connector between institutions and individuals who needed something from each other but lacked a direct channel. The merger talks between Julius Baer and Edmond de Rothschild are the clearest example: two banks that competed for the same client base, brought together by a man whose primary credential was knowing people who controlled large amounts of money.

The Southern Trust contract adds a layer of complexity. If the $25 million was payment for legitimate financial technology, no public evidence of that technology has surfaced. If it was payment for Epstein's role in facilitating the merger talks, the amount suggests either extraordinary value placed on his introductions or a relationship that extended beyond a single transaction. If it was something else, the contract's vague language provides cover for a transfer that might not withstand scrutiny under its stated terms.

Collardi left Julius Baer in 2017 to join Pictet, another Geneva-based private bank. He has not publicly addressed his interactions with Epstein. Ariane de Rothschild remains in her role at Edmond de Rothschild, pending the outcome of the board's review.

What the Documents Show

The financial documents assembled by Drop Site News, Inside Paradeplatz, and investigative journalist Lucy Komisar trace a network of Swiss banking relationships that placed Epstein at the intersection of some of Europe's most established financial institutions. The merger talks, the Southern Trust contract, and the UBS transfers describe a system in which Epstein functioned not as a client of Swiss banks but as a participant in their strategic decision-making.

Swiss financial regulators have not announced any investigation into the Epstein-related transactions. FINMA, the Swiss Financial Market Supervisory Authority, has broad authority to investigate potential violations of anti-money laundering regulations but has historically been reluctant to pursue cases involving the country's largest private banks.

The merger that never happened and the contract that produced no visible product remain open questions in the financial record. They suggest that Epstein's value to Swiss banking was not in what he built or managed, but in what he knew and whom he could reach.
