Swiss Centennial Bank Banque SyzUP Splits Over Bitcoin, Son Takes Team and Assets to Build Europe's Largest BTC Treasury

Managing 25.8 billion Swiss francs in assets, Geneva-based century-old private bank Banque Syz was torn apart over a crypto asset integration proposal—leading to the departure of founder’s son Marc Syz and business partner Richard Byworth, who started a new Bitcoin treasury company. Bloomberg reports that the trigger was a Bitcoin project worth less than 1% of the bank’s total AUM.

A Swiss private bank managing 2.58 billion francs clashed over a plan to consolidate 3,500 Bitcoin—roughly 0.9% of the bank’s total AUM at current prices. For that 0.9%, father and son fell out, top executives left. The data shows: the issue was never Bitcoin itself.

Board says no, father and son say goodbye

According to Bloomberg, the incident started when Marc Syz proposed integrating Future Holdings AG, a crypto asset company, into Syz Capital, the alternative assets division founded by his father, Eric Syz. Under Marc’s leadership, Syz Capital’s AUM grew to about 2 billion Swiss francs (roughly $2.5 billion), with Marc holding about 20% and partner Richard Byworth about 5%.

The plan nearly went through, but the bank’s board withdrew approval citing risk concerns. Bloomberg reports that the board then demanded Marc and Byworth resign from their director roles at Future Holdings. Their response was straightforward—leaving the entire bank. COO Boris Chave also left, and Syz Capital is now run by group CFO Christoph Raninger.

This personnel shake-up occurred at a delicate time: Eric’s other son, Nicolas Syz, took over as CEO in February 2026, and Eric’s wife, high-end jewelry designer Suzanne Syz, is on the board. The family governance is complex—more like a multi-layered crypto protocol’s on-chain voting.

25.8 billion francs, stagnant for five years

To understand this split, consider one number: Banque Syz’s total AUM was 25.8 billion francs at the end of 2024, roughly unchanged from five years earlier.

Bloomberg frames it as a “crypto vs. traditional” generational clash, but the data reveals another issue: a boutique private bank with stagnant assets facing growth bottlenecks in a super-low interest rate era. When aggressive growth strategies are rejected, what do the remaining players prioritize? Marc’s departure isn’t just about ideology; it’s about rejecting the bank’s refusal to take measurable risks.

Eric Syz founded the bank in 1996; the family’s roots trace back to the 1850s textile industry. In 2020, he reorganized, selling retail asset management business Oyster to focus on high-net-worth clients. The strategic direction was forward-looking, but execution fell short.

Marc’s next move: Bitcoin treasury company

After leaving, Marc and Byworth’s plans became public. Bloomberg reports that Future Holdings had merged with Swedish-listed H100 Group AB and raised 28 million Swiss francs (about $34.5 million). Their next step is to partner with Stifel Financial Corp to list Future Holdings in both Sweden and Switzerland, aiming ultimately for a primary listing on the Swiss stock exchange—Europe’s third-largest liquidity market, with a relatively crypto-friendly regulatory environment.

Marc’s public goal: accumulate over 3,500 Bitcoin to become Europe’s largest Bitcoin treasury company. He also plans to establish an independent asset management firm to compete directly with his former employer, focusing on capital preservation and alternative growth strategies.

This business model is clearly inspired by Michael Saylor’s Strategy Inc. (formerly MicroStrategy).

Bloomberg provides an important context: after Trump’s election, many crypto treasury companies emerged, with valuations often exceeding their actual crypto holdings. But as prices fell, many listed Bitcoin treasury firms dropped to or below net asset value.

In other words, Marc’s timing to enter the space coincides with the most fragile valuation logic. The core appeal of Bitcoin treasury companies is “using stock premiums to finance Bitcoin purchases, leveraging exposure”—a strategy effective in optimistic markets. When premiums vanish, holders are left with a more expensive, less transparent tool than simply buying Bitcoin directly.

3,500 Bitcoin, at current prices, is about $350 million. Achieving this requires ongoing financing, which depends on market willingness to pay premiums. Premiums depend on continued market optimism—a chain of assumptions that must all hold.

Two generations, each choosing a difficult path

In conclusion: Marc’s view of traditional private banking is fundamentally correct. A boutique private bank with stagnant AUM over five years faces structural pressures that won’t disappear with a new CEO. The board’s rejection of crypto integration preserves risk control but closes a growth window.

But Marc’s alternative path is also fraught with uncertainty. The bubble logic of Bitcoin treasury companies has already shown its pitfalls in multiple cases. Whether the “Europe’s largest” title can be realized depends on future Bitcoin prices and market revaluation of these tools.

The father maintains a non-growing bank; the son races toward a new, valuation-challenged sector. The Swiss banking industry’s generational shift resembles more a gamble on two different bets than a clear inheritance.
