EFG International: A true leader as a Swiss Custodian Bank

Switzerland has long been a global financial hub, known for its stability and sophisticated banking system. Among the prominent institutions that have thrived in this environment, EFG International (EFG) headquartered in Zurich stands out as a true leader. It has become an exceptional custodian bank, particularly for international clients, including Americans, who wish to hold assets in Switzerland.

Alpen Partners, an independent Swiss wealth management firm, serving international clients from over 30 countries worldwide, proudly maintains a strong partnership with EFG International as a preferred custodian bank in Switzerland.

A glimpse into EFG history

EFG, previously known as the European Financial Group, was founded in 1995, making it a relatively young institution compared to some of its venerable Swiss counterparts. However, its youth was accompanied by dynamism and a relentless commitment to providing a wide range of financial services. The bank has grown steadily since its inception, becoming a key player in Switzerland’s banking sector.

EFG’s journey to prominence was marked by strategic acquisitions expanding its presence in Switzerland and globally, establishing a strong foundation for its future growth.

EFG has around 2,700 employees worldwide and at the end of 2022 had assets under management totaling CHF 143.1 billion, and has a strong capital position along with a highly liquid balance sheet. Listed on the SIX Swiss Exchange since 2005, EFG offers financial security and solidity. They are committed to being a leading independent partner to their clients.

The bank’s remarkable history, coupled with its core values, has made it a trustworthy partner for Alpen Partners’ international clients seeking custodian services in Switzerland.

The Swiss advantage

Switzerland’s enduring reputation as a financial haven is based on its political stability, neutrality, and stringent banking regulations. The nation’s commitment to preserving client confidentiality and privacy, as well as its long-standing tradition of providing impeccable wealth management services, has made it an attractive destination for high-net-worth individuals and institutions worldwide.

EFG leverages these Swiss advantages, offering international clients, including Americans, an opportunity to tap into Switzerland’s remarkable financial ecosystem.

By providing comprehensive and accurate reporting documents, EFG empowers its clients to navigate the complexities of tax compliance, assuring them of a smooth and legally sound financial journey.

Wealth Management

Following the establishment of his Swiss banking structure, David required a coordinated framework to manage assets across jurisdictions while maintaining compliance with U.S. reporting obligations.

Alpen integrated his assets into a Swiss wealth management structure tailored for internationally active clients. The focus was on aligning investment strategy, currency exposure, and financial planning within a single cross-border framework.

Through Alpen’s wealth management services, David gained access to

  • Global investment advisory, allowing participation in international markets while considering U.S. regulatory requirements
  • Multi-currency portfolio management, reducing reliance on a single currency exposure
  • Cross-border financial planning, supporting his relocation and long-term wealth objectives
  • Centralized oversight of assets held with Swiss custodian banks

Switzerland’s stable political environment, strong financial sector, and long-standing expertise in wealth management provided a reliable foundation for administering David’s international assets.

Offshore Banking Structure

With the Swiss account in place, Alpen integrated it into a broader offshore banking structure designed for diversification and asset protection.

This framework allowed David to

  • Hold assets across multiple currencies
  • Access international investment opportunities
  • Diversify assets outside a single jurisdiction
  • Ensure the highest standards of financial privacy while maintaining full transparency for international reporting

The Swiss banking environment also offered political stability, robust financial regulation, and a historically strong currency base.

Relocation and Swiss Residency Path

As part of his relocation planning, David explored the process of establishing residency in Switzerland. For non-EU citizens such as U.S. nationals, residency typically requires either employment in Switzerland, the establishment of a local company, or a negotiated tax arrangement with cantonal authorities.

Working alongside local legal and tax advisors, Alpen helped David evaluate the available options and coordinate the financial aspects of the move. This included aligning banking structures, documenting international assets, and preparing financial disclosures required during the residency process.

Swiss Bank Account Setup

Opening a Swiss bank account as a U.S. client follows a defined onboarding process based on regulatory requirements and internal bank standards. This includes identity verification, source-of-wealth documentation, and alignment with international reporting frameworks. It also involves coordination with the selected institution, including the negotiation of account terms and applicable fee structures.

Alpen supported David throughout this process by coordinating each step

  • Assessing eligibility and identifying Swiss private banks experienced with U.S. clients
  • Preparing and reviewing required documentation, including passport verification, financial history, and source-of-funds evidence
  • Advising on account structures (e.g. personal vs. investment accounts) aligned with his objectives
  • Coordinating communication with the selected bank and managing the submission process

As part of the onboarding, David was required to provide detailed documentation regarding his financial background and the origin of his assets. Minimum deposit thresholds and internal bank criteria were also considered when selecting the appropriate institution.

Once all documentation was complete and approved, the account opening process typically took approximately 1–2 weeks. Alpen then coordinated the initial asset transfers and ensured a smooth transition from existing banking relationships.
