EFG International to Acquire Quilvest Switzerland in All-Cash Deal: What the 2026 Private-Banking Move Means

Zurich, Switzerland (January 26, 2026) — Swiss private banking group EFG International announced it will acquire Quilvest (Switzerland) Ltd, a Zurich-based private bank known for deep relationships in Latin America and a strong focus on ultra-high-net-worth individuals (UHNWIs). The transaction will be paid entirely in cash and is expected to close in the third quarter of 2026, subject to regulatory approvals.

According to the information released alongside the announcement, Quilvest (Switzerland) has approximately CHF 5.3 billion in client assets in total, consisting of around CHF 3.9 billion in assets under management and about CHF 1.4 billion in assets under custody. EFG said it expects the acquisition to reduce its Common Equity Tier 1 (CET1) capital ratio by up to roughly 70 basis points once completed.

Who Is Quilvest (Switzerland) and Why Does It Matter?

Quilvest (Switzerland) is not a “newcomer” bank chasing quick growth. It traces its roots back to 1932, when it was founded by the Argentinian Bemberg family. Today, the bank is fully owned by Bemberg Capital, a Luxembourg-based holding linked to the family. That history matters in private banking because long-standing family networks can create multi-generation client relationships—exactly the kind of relationships that are difficult to build from scratch.

In wealth management, relationships are a major asset. Clients often stay with trusted advisors for decades, especially when the bank has specialized knowledge—such as managing complex cross-border wealth, handling multi-jurisdiction reporting needs, and building investment portfolios that include both public and private markets. Quilvest Switzerland is described by EFG as having a particularly established footprint in Latin America and expertise advising UHNWIs, including on private market investments (such as private equity, private credit, or other less-liquid strategies).

In simple terms: EFG isn’t just buying an office or a brand name. It’s trying to acquire a set of client relationships, advisory talent, and a geographic “bridge” between Switzerland and growth markets—especially Latin America—while also strengthening its position in other regions mentioned in the announcement.

Why EFG International Is Doing This Now

EFG’s public messaging points to strategic growth—specifically growth across Switzerland, the Middle East, and the Americas. EFG’s CEO Giorgio Pradelli described the transaction as a partnership opportunity with the Bemberg family and a way to add to EFG’s growth trajectory in these regions.

To understand why this matters, it helps to look at broader forces shaping private banking:

1) Private banking is consolidating

Across Switzerland and Europe, private banks face rising compliance costs, technology investment needs, and client demand for more sophisticated services. Smaller firms can struggle to keep pace alone. That environment tends to push the industry toward mergers and acquisitions where a larger platform can absorb costs and scale services more efficiently.

2) UHNW clients want “global but personal”

Many UHNW clients want the personal touch of a boutique private bank, but they also want the security, product range, and operational strength of a larger institution. A combined EFG–Quilvest Switzerland platform can be pitched as delivering both: relationship-driven private banking plus a bigger global engine behind it.

3) Private markets are becoming mainstream for the wealthy

High-net-worth and ultra-high-net-worth portfolios increasingly include private equity, private credit, venture, and other “private market” allocations. Banks that can source, evaluate, and manage these investments—while educating clients about risks like illiquidity—often differentiate themselves. EFG highlighted Quilvest Switzerland’s track record in advising on private market investments, signaling that this capability is part of the strategic logic.

How Big Is the Acquisition, Really?

Quilvest Switzerland’s client assets of about CHF 5.3 billion are meaningful, but what matters even more is the quality of those assets. In wealth management, “quality” often means:

Sticky relationships (clients who stay for years, not months)
High advisory value (complex needs where the bank provides planning and investment expertise)
Healthy margins (profitability after service costs)
Balanced client geography (diversification across regions and currencies)

EFG described Quilvest Switzerland as a “pure-play” Swiss private bank and emphasized UHNW focus and Latin American footprint. Those phrases usually signal that the target serves a niche with potentially strong long-term relationship value.

The Money Side: All-Cash Purchase and Capital Impact

The transaction is structured as an all-cash acquisition of all shares of Quilvest Switzerland. For EFG, paying cash can be attractive because it avoids dilution that might come from issuing new shares. But cash deals can also reduce capital ratios, which is why EFG specifically called out the expected impact on its CET1 capital ratio.

What is CET1 and why does “70 basis points” matter?

CET1 (Common Equity Tier 1) is a key measure of a bank’s core capital strength. Regulators and investors watch it closely because it reflects a bank’s ability to absorb losses. A change of 70 basis points means 0.70 percentage points. Whether that’s “big” depends on EFG’s starting ratio and capital planning—but the fact that EFG quantified it suggests they want the market to understand the impact is manageable and expected.

In practice, a bank undertaking acquisitions often balances three goals:

Growth (more client assets and stronger capabilities)
Profitability (earning power after integration costs)
Capital resilience (maintaining buffers above regulatory requirements)

By stating the expected CET1 reduction up front, EFG is addressing the capital-resilience question early.

Timeline: What Happens Between Now and Q3 2026?

Even when a deal is announced, it is not final until approvals and closing steps are completed. Based on the announcement, the expected closing is in Q3 2026 and remains subject to regulatory approval.

Typical steps in a private bank acquisition

While every case differs, transactions like this commonly involve:

Regulatory review (Swiss authorities and potentially other jurisdictions depending on operations and clients)
Client communication (explaining what changes and what stays the same)
Integration planning (systems, compliance frameworks, product platforms)
Advisor retention (keeping relationship managers who are central to client trust)
Operational migration (transitioning custody, reporting, and internal processes)

Because private banking is relationship-led, the “human factor” matters as much as the legal paperwork. The combined group will likely focus heavily on continuity—making clients feel that service remains personal, stable, and confidential, while also demonstrating the benefits of a broader platform.

What It Could Mean for Clients of Quilvest Switzerland

If you’re a client of Quilvest Switzerland, the biggest immediate question is usually: “Will my day-to-day service change?” In many private-bank acquisitions, banks aim for a “continuity first” approach—keeping relationship managers and core client service stable during the transition, while gradually introducing additional products or capabilities from the larger group.

Potential benefits clients might see

Broader investment platform (more products, research, and solutions)
Expanded geographic coverage (helpful for families with multiple residences or businesses)
Enhanced infrastructure (reporting, digital tools, compliance support)

Potential concerns clients often watch

Changes in fees or pricing structures
Changes in investment approach (for example, model portfolios vs. bespoke mandates)
Advisor turnover (clients may follow relationship managers if they leave)
Onboarding or paperwork requests due to compliance harmonization

Because the closing is expected later in 2026, clients may experience a phased communication plan—first explaining the strategic rationale, then outlining practical steps closer to closing.

What It Could Mean for EFG: Growth in Switzerland, Middle East, and the Americas

EFG explicitly linked the acquisition to growth across Switzerland, the Middle East and the Americas. That’s notable because many private banking groups pursue “corridors” of wealth: client flows between regions shaped by business ties, family connections, and investment opportunities.

Quilvest Switzerland’s Latin American footprint may strengthen EFG’s position with:

Entrepreneurs with businesses operating across Latin America and Europe
Family offices seeking stable Swiss booking and advisory
Multi-generational families managing succession, philanthropy, and cross-border structures

EFG may also see Quilvest Switzerland as a “capability add,” particularly if Quilvest’s private market advisory track record complements EFG’s broader offering and helps attract or retain UHNW clients who want access to differentiated investments.

Industry Context: Why This Deal Fits a Wider Pattern

Swiss private banking is still a global hub, but it’s not frozen in time. The market has been evolving for years—technology expectations have risen, compliance obligations remain demanding, and clients increasingly want an integrated view of their wealth (banking, investments, estate planning, credit, and sometimes even lifestyle services).

In that environment, acquisitions can be used to:

Add scale (more assets and revenue base)
Add talent (relationship managers and specialists)
Add geography (client networks in specific regions)
Add expertise (private markets, structured solutions, or niche advisory)

Public reporting and company updates show EFG has used acquisitions to expand its wealth management footprint in recent periods, indicating that “inorganic growth” remains an important lever in its strategy.

Risks and Challenges: What Could Go Wrong?

No matter how logical a deal looks on paper, execution determines success. Here are the major challenge areas investors and clients typically watch in private bank acquisitions:

1) Retaining relationship managers and key teams

In private banking, clients don’t just “belong” to the brand; they often feel loyal to the advisors who know their family situation and financial goals. If key people leave, assets can follow them. That’s why staff retention plans and cultural fit matter.

2) Integration complexity

Combining compliance processes, client onboarding standards, IT systems, and reporting can be time-consuming. A slow or confusing migration can frustrate clients—especially UHNW clients, who expect a seamless experience.

3) Regulatory and cross-border scrutiny

Cross-border wealth management is heavily regulated. Regulators focus on client suitability, anti-money laundering controls, and governance. Approvals can take time, which is one reason the expected closing is only in Q3 2026.

4) Capital management

EFG already signaled a potential CET1 ratio reduction of up to ~70 basis points. If market conditions change—such as increased risk costs or new regulatory expectations—capital planning can become more delicate. The bank will aim to show it can pursue growth while staying well-capitalized.

Conclusion: A Relationship-Driven Acquisition With a Long Runway

EFG International’s plan to acquire Quilvest Switzerland is a classic private-banking play: add specialized client relationships, deepen regional corridors (especially involving Latin America), and expand advisory capabilities—while aiming to keep client experience stable throughout integration. With a closing targeted for Q3 2026 and the deal funded in cash, the next chapters will be shaped by regulatory approvals and the practical work of integration.

If execution goes well—particularly advisor retention and client continuity—the acquisition could strengthen EFG’s position in the Swiss private banking landscape and support the growth ambitions it highlighted across Switzerland, the Middle East, and the Americas. If execution slips, the same relationship-driven nature of private banking that makes this acquisition attractive could also amplify challenges. Either way, this is a deal to watch closely through 2026.
