Building a relationship with a private bank offshore isn’t about secret accounts or dodging taxes. It’s about accessing a higher level of service, more stable jurisdictions, multi-currency capabilities, and sophisticated investment or lending solutions. The bar to qualify has risen sharply over the past decade, and banks now care as much about the clarity of your story and compliance profile as they do about your balance. This guide distills how private banks actually decide who qualifies, what you’ll need to prepare, and how to move from application to a funded account without derailing on compliance.
What Private Offshore Banking Really Is
Private offshore banking means holding assets with a regulated bank outside your country of residence, typically in a financial center known for strong regulation and investor protection. “Private” refers to dedicated relationship management and investment services for high-net-worth clients, not secrecy.
What clients actually get:
- A relationship manager and investment specialists
- Multi-currency accounts and forex at institutional pricing
- Custody of securities across global markets
- Lending against portfolios (Lombard loans) and structured credit
- Access to funds, alternatives, and IPOs that retail channels rarely offer
- Estate planning and trust coordination
Banks differentiate between tiers:
- Priority/International affluent: generally USD/EUR/CHF 250k–1m minimum, limited advice
- True private banking: typically USD 1–5m+ in assets with the bank
- Ultra-high-net-worth: USD 25m+ with bespoke credit, direct deals, and family office services
There are exceptions, but if you’re planning with less than roughly USD 500k–1m, you’ll likely be steered to “international” retail or fintech options rather than full private banking.
Who Actually Qualifies
Banks think in three dimensions: assets, profile risk, and profitability.
- Assets: A common minimum for private banking is USD 1–5m in investable assets. Some Swiss/Luxembourg desks will start at USD 1m for clean, straightforward profiles. Singapore and Monaco often prefer USD 2m+. Smaller Caribbean or Channel Islands banks can consider USD 500k–1m if the rest of the profile is strong.
- Profile risk: Low-risk clients are those with clear, documented wealth, straightforward tax residency, and no political exposure. High-risk may include certain industries (e.g., extractives, gambling), countries with weak AML regimes, or clients with complex webs of entities without a clear rationale.
- Profitability: Many banks now require you to place assets under management (AUM) with them—discretionary or advisory—rather than pure custody. Expect a minimum advisory or custody fee and potential transaction/FX revenues. A “custody-only” relationship is often possible above USD 2–5m.
As a rule of thumb: If you can place USD 2m+ and keep the story simple and well-documented, you’ll have options in major booking centers.
Picking the Right Jurisdiction
Switzerland
- Strengths: Deep private banking ecosystem, strong investor protection, broad investment menu, stable currency and polity.
- Considerations: Many desks prefer USD/EUR 1–5m+. Strict on source-of-wealth; US persons often need an SEC-registered advisory channel.
Singapore
- Strengths: Asia time-zone coverage, robust regulator (MAS), access to Asia managers and private markets, English-speaking.
- Considerations: Minima often USD 2–5m. More sensitive to complex corporate structures. Strong AML checks.
Luxembourg
- Strengths: EU market access, strong fund administration, life assurance wrappers (unit-linked).
- Considerations: Favours European clients; banks often want USD/EUR 1–3m+.
Monaco, Liechtenstein, Channel Islands, Isle of Man
- Strengths: Well-trodden for European/UHNW clients, trust and wealth planning hubs.
- Considerations: Thresholds vary widely; often EUR/GBP 1–5m. Monaco likes ties to EU or residency pathways.
Caribbean (Cayman, Bahamas) and Mauritius
- Strengths: Structuring hubs, trusts/funds, more flexible for certain nationalities.
- Considerations: Reputation-sensitive; ensure the specific bank has strong, recognized compliance standards.
UAE (DIFC/ADGM)
- Strengths: Tax-efficient, growing wealth hub, convenient for MENA/India/Africa clients.
- Considerations: Banks range from global players to local institutions with varied due diligence standards.
Your decision should weigh:
- Time zone and language
- Your primary currency and forex needs
- The bank’s acceptance of your nationality/industry
- Tax treaties and reporting (CRS/FATCA)
- Availability of services you need (lending, EAM platform, alternatives)
The Compliance Reality: What Banks Must Satisfy
Private banks comply with stringent AML/CFT (anti-money laundering/countering financing of terrorism) rules. That translates into deep questions about your life, business, and taxes. If the story is clear and the paper trail is coherent, onboarding is smooth. If not, it stalls.
Key frameworks and what they mean for you:
- KYC and Source of Wealth: Banks must understand how you made your money—over time—not just the source of the incoming funds for this account.
- Source of Funds: Banks verify where the money funding the account is coming from for each transfer.
- PEP screening: If you are a politically exposed person (or a close relative/associate), expect heightened scrutiny and often higher minima.
- Sanctions and adverse media: Negative press, legal disputes, or connections to sanctioned countries trigger escalations.
- FATCA (for US persons) and CRS (for most other jurisdictions): Automatic exchange of account information with your tax authorities. You will self-certify your tax residency and may need to provide tax IDs.
US Persons: Special Considerations
Many offshore private banks do not onboard US persons directly due to SEC and tax complexity. Workarounds:
- Use a bank that supports US clients via an SEC-registered external asset manager (EAM) or an affiliated onshore advisory platform.
- Expect Form W‑9, annual 1099 reporting equivalents, and limited access to non-US mutual funds (PFIC rules). UCITS funds are generally off-limits for taxable US persons; you’ll be steered to US-compliant funds/ETFs.
- Minimums for US clients are often higher (USD 2–5m+) and fees can be slightly higher due to compliance overhead.
If you hold a US passport but reside abroad, disclose this upfront. Banks will find out and offboarding a US client after onboarding is far more painful than a direct rejection.
Build a Bankable Profile: The Pre-Qualification Checklist
Before approaching any bank, assemble a tight, consistent profile. I usually prep clients with a two-part pack: a narrative summary and evidentiary documents.
Narrative summary (2–3 pages):
- Personal overview: citizenships, residency(ies), family background
- Professional history: current and prior roles, businesses, exit events
- Wealth composition: real estate, operating companies, listed securities, cash, private equity
- Source-of-wealth timeline: how the wealth accumulated over the years, with key milestones
- Tax residency and compliance: current tax residency, filing status, advisors engaged
- Intended use of the account: custody, investment, FX, lending, corporate treasury, etc.
- Expected flows: initial funding amount, frequency of transfers, geographies, currencies
Evidence package (certified where required):
- Passport(s) and government ID
- Proof of address (utility bill/bank statement dated within 3 months)
- Bank statements showing current liquid assets and origin of the initial transfer
- CV or professional biography
- Tax returns or tax residency certificate (if available)
- Wealth evidence: sale agreements, dividend vouchers, audited financials, employment contracts/bonus letters, inheritance documents, property sale deeds, cap table and SPA for exits
- For business owners: corporate registry extracts, share certificates, UBO chart, recent financials, major contracts, board resolution to open account
- Professional references (banker/lawyer/CPA), if the bank asks
- For trusts/foundations: trust deed or foundation statutes, protector/settlor details, letters of wishes, and UBO disclosure
Pro tip: Prepare digital folders mirroring the bank’s KYC structure. Label everything clearly and include brief context notes. A clean pack can cut weeks off onboarding.
Personal vs. Entity Accounts
Private banks will open accounts for:
- Individuals (classic private banking)
- Companies (holding or operating companies)
- Trusts and foundations
- Investment partnerships or family investment companies
When to use an entity:
- Estate planning or multi-heir governance
- Separation of operating business risk from investment assets
- Cross-border holding of private investments
- Currency and legal risk diversification
Keep structures purposeful and simple. An opaque chain of entities across three jurisdictions without a clear reason is a compliance red flag. Use a single, well-administered holding entity if it meets your goals, and keep management and accounting up to date. Provide an org chart with percentages all the way to the ultimate beneficiaries.
How Banks Evaluate Source of Wealth
Think of source of wealth (SOW) as your life story in numbers. Banks want to see a credible arc:
- Early career and savings
- Business build-up, dividends, or salary progression
- Liquidity events (business sale, property sale, inheritance)
- Investment gains with a plausible base and timeline
Strong evidence examples:
- Signed SPA and bank credit for proceeds of company sale
- Tax filings reflecting dividends/bonuses that match bank statements
- Property sales with land registry records
- Inheritance documentation plus probate
- Brokerage statements showing accumulative investments and distributions
Weak or risky signals:
- Large cash deposits without trail
- “Gifts” without supporting wealth of the giver
- Crypto proceeds without audit-quality exchange/bank records
- Frequent address, job, or jurisdiction changes without explanation
If crypto is part of the story, present exchange KYC, on-chain analysis (if available), fiat off-ramps, and tax reporting. Some banks will still decline; others will accept limited exposure if everything is fully documented.
Step-by-Step Onboarding Timeline
Every bank has its rhythm, but this is a realistic path I see often:
Week 0–1: Pre-screening
- You or your introducer shares a short profile with the bank: nationality, residence, expected AUM, industry, PEP status, and use case.
- Bank indicates appetite and ballpark minimums/fees.
Week 1–3: Document collection
- You build the KYC/SOW pack. Get notarized/certified copies where requested. Some banks need apostilles.
- Align story with evidence; fix inconsistencies (e.g., addresses and dates).
Week 3–4: Submission and compliance intake
- Relationship manager (RM) submits the file. Expect clarifications.
- Adverse media and sanctions screening kick off.
Week 4–8: Interviews and deeper due diligence
- A video or in-person meeting to walk through your background and objectives.
- Follow-up document requests (bank statements, contracts).
Week 8–10: Approval and account opening
- Account numbers issued (IBAN/SWIFT). Online banking setup.
- Investment mandate discussions finalize.
Week 10–12: Initial funding and activation
- First transfer lands; the bank verifies source of funds for this specific transaction.
- Portfolio implementation or custody-only setup begins.
Some profiles complete in 4–6 weeks; higher-risk or complex cases can take 12–16 weeks.
Investment Mandates, Fees, and Lending
Most private banks will ask how you plan to invest and at what risk level. You’ll choose from:
- Discretionary mandate: Bank manages the portfolio. Typical all-in fees 0.8%–1.5% per year, tiered by size and strategy.
- Advisory mandate: You make final calls; the bank provides ideas and execution. Advisory fees plus transaction costs; all-in often 0.6%–1.2%.
- Execution-only/custody: You trade or hold via an external advisor. Custody 0.1%–0.3% plus trade/FX fees. Some banks require higher minimums for custody-only.
Other costs:
- FX spreads: often 10–40 bps for majors at private banks, tighter for large tickets
- Brokerage: varies widely, often a few bps for liquid markets
- Alternatives access: feeder fund fees and carry stack; watch for layers
- Performance fees: charged by certain mandates/funds; understand the high-water mark
Lombard lending:
- Borrow against your portfolio for liquidity or leverage. Typical loan-to-value (LTV) 40%–70% depending on asset quality; rates often benchmark plus a spread.
- Collateral is marked-to-market daily; margin calls apply. Don’t rely on Lombard credit for illiquid needs.
How Much Cash vs. Investments
Banks are not money warehouses. If you park USD 5m in cash, you won’t be a profitable client unless you engage in FX or invest. A workable split many clients use:
- 6–12 months of anticipated spending/FX needs in cash
- The rest in a diversified portfolio aligned with your goals
- For treasuries: money-market or short-duration instruments for yield with liquidity
Remember that deposit insurance limits (e.g., Switzerland’s esisuisse around CHF 100k per depositor per bank, Singapore’s SDIC caps vary) apply only to cash deposits. Securities are typically held in segregated custody and not on the bank’s balance sheet, which reduces counterparty risk.
Corporate, Treasury, and Entrepreneur Use Cases
If you’re an entrepreneur or investor with operating companies:
- Operating accounts offshore are harder to open unless the company has real substance and commercial justification. Be prepared to show contracts, invoices, and payroll/substance (especially post-BEPS).
- Holding companies for investments are more acceptable. Provide a clear investment policy and capital origins.
- Treasury centralization: Some families keep portfolio assets at a private bank and operational cash at a commercial bank closer to the business. Don’t mix operating flows with investment custody unless the bank encourages it.
For corporate accounts, expect:
- Articles/incorporation certificates, directors’ registers, shareholder registers
- UBO chart to natural persons
- Board resolution to open accounts and appoint signatories
- Financial statements and tax filings where available
- Proof of business activity: contracts, invoices, website, leases, and staff evidence
Using External Asset Managers (EAMs) and Introducers
An EAM is an independent investment advisor with agreements across multiple banks. Benefits:
- Access to banks that won’t onboard you directly (especially for US persons)
- Negotiated pricing and broader product shelves
- A single advisor across several custodians and jurisdictions
- Advocacy during compliance escalations
A good introducer or law firm can:
- Pre-match you with receptive banks for your profile and nationality
- Tighten your SOW narrative and documentation
- Sequence the process to cut time to account opening
Choose regulated EAMs/advisors with a real track record. Avoid “fixers” who promise shortcuts—those shortcuts rarely last.
Common Mistakes That Get Files Stuck
I see the same avoidable errors repeatedly:
- Underfunding: Approaching a private bank with USD 200k and asking for full-service onboarding. Use international retail desks or build to the minimum first.
- Messy addresses and tax residency: Your IDs, bank statements, and tax residency should tell a consistent story. If you moved, explain it.
- Inconsistent source-of-wealth: Don’t cite a business sale without an SPA, or dividends without matching financials and bank credits.
- Overengineering structures: Layered entities in three offshore centers with nominee directors and no business purpose = compliance purgatory.
- Crypto opacity: If crypto is part of the wealth, provide a robust, auditable trail or expect rejection from many banks.
- Hiding US person status or PEP links: The screening will reveal it. Disclose early with documentation to manage the narrative.
- Mixing business and personal flows: Decide whether the account is for you, your trust, or your company. Keep it clean.
Case Studies: How Profiles Play Out
1) Latin American entrepreneur with a business sale
- Profile: 42-year-old sold a logistics company; proceeds USD 8m. Lives in Mexico; no PEP ties.
- Approach: Switzerland and Luxembourg shortlists. Presented SPA, notarized share registry, and post-closing bank credits. Provided three years of tax returns and a simple holding company.
- Outcome: Onboarded in 9 weeks; advisory mandate at 0.85% all-in; Lombard line at 60% LTV for opportunistic real estate. Clean audit trail was decisive.
2) European tech executive with RSUs and bonuses
- Profile: 36-year-old in Germany with USD 1.4m liquid after vesting stock and bonuses. Wants Asia exposure and career relocation flexibility.
- Approach: Singapore private bank considered; prepared employer letters, vesting schedule, broker statements, and tax filings. Risk appetite moderate; wants execution-plus-advisory.
- Outcome: Onboarded in 7 weeks with USD 1.2m initial funding. Custody plus advisory, FX savings on EUR/USD. The clarity of salary/RSU trail and tax compliance made it straightforward.
3) High-risk mismatch and how to pivot
- Profile: 50-year-old consultant, various passports, frequent country moves, cash-heavy revenues, significant crypto holdings.
- Approach: Initially applied to a Tier-1 Swiss bank; file stalled on SOW and cash components.
- Pivot: Engaged a regulated EAM with a bank more open to crypto with full documentation. Delivered on-chain analysis, exchange KYC, and tax filings. Reduced complexity by using a single investment company with audited accounts.
- Outcome: Onboarded in 14 weeks at a different custodian; custody-only with a higher minimum and strict conditions. Preparation and transparency saved the application.
Managing Tax and Reporting
- Clarify tax residency before onboarding. You will sign CRS self-certifications and possibly provide a Tax Residency Certificate.
- If you’re a US person: file FBAR/FinCEN 114 and FATCA Form 8938 as applicable; be careful with PFIC rules if offered non-US funds.
- If you hold entities: understand CFC and attribution rules in your home country. Don’t rely on bank secrecy; assume transparency via CRS.
- Life assurance wrappers (e.g., Luxembourg) can simplify reporting for some Europeans, but they must fit your tax regime.
Use a cross-border tax advisor. Banks provide forms but do not design your tax structure.
Picking the Bank: What to Ask
Interview banks as much as they interview you. Questions that separate marketing from reality:
- What’s your minimum AUM for my profile and nationality?
- Do you require discretionary or advisory mandates, or will custody-only work?
- What are your all-in costs at my expected AUM, including custody, trading, FX, and retrocessions?
- Which booking center will hold my account, and why?
- Do you work with external asset managers? Accept US persons (if applicable)?
- What lending is available against my portfolio? Typical LTVs?
- How quickly can you execute account opening, and what documents usually delay clients like me?
Ask to speak to the actual RM and, if possible, an investment specialist. The quality of your day-to-day team matters more than the logo on the door.
Practical Fee Benchmarks
While every bank structures pricing differently, these ranges are common:
- Custody-only: 0.10%–0.30% p.a. on assets
- Advisory/discretionary: 0.60%–1.50% p.a. all-in, tiered by size
- FX spreads: 0.10%–0.40% on majors; larger tickets can price tighter
- Brokerage: from a few basis points on liquid markets
- Account opening: some banks charge a one-time fee (hundreds to a few thousand), many waive it at higher AUM
- Alternatives access: feeder fund admin 0.10%–0.50% plus underlying fees and carry
Push for transparency. Ask for a worked example on a USD 2m portfolio with your anticipated trading and FX volume.
How to Prepare for the Compliance Interview
Treat it like an investor meeting:
- Know your numbers: dates, amounts, counterparties for big events
- Keep the story consistent with documents and public sources
- Be upfront about sensitive items (e.g., litigation, crypto, or past tax amnesty). Surprises late in the process are fatal
- Explain the purpose of the account: investment policy, currencies, expected inbound and outbound flows
- If using an entity, explain its purpose, governance, and how it is administered
Your RM is your internal advocate. Make it easy for them to say yes.
Ongoing Maintenance: Staying Bankable
After opening, you still need to pass periodic reviews:
- KYC refresh: Every 1–3 years or on trigger events. Keep ID, proof of address, and tax residency current.
- Transaction rationale: Large or unusual transfers may require explanations and supporting invoices/contracts.
- Thresholds: Keep AUM above the agreed minimums. Significant drops may trigger fee changes or relationship reviews.
- Profile updates: Inform the bank about changes in residency, citizenship, or PEP status. Better to be early than reactive.
Respond promptly and completely to compliance requests. Non-responsiveness is a common reason for account freezes or closures.
Risk Flags and How to Mitigate Them
Red flags that often lead to rejections:
- Unclear tax residency or multiple residencies without explanation
- Adverse media involving fraud, corruption, or sanctions
- Complex structures with nominee shareholders and no economic rationale
- Industries with heightened AML risk without robust compliance (e.g., money services, gambling)
- High cash components or unverifiable sources
- Crypto proceeds without an auditable trail
- PEP ties not disclosed upfront
Mitigations:
- Provide certified, high-quality documentation and consistency across all disclosures
- Reduce structural complexity; use professional administrators
- Engage credible legal/accounting advisors; include opinion letters if needed
- Use regulated EAMs familiar with your profile and target banks
- Start with a conservative mandate and build trust; you can evolve later
Switzerland vs. Singapore vs. Others: A Quick Decision Lens
- If you need Europe-centric investments, CHF/EUR base currency, and deep private banking history: Switzerland/Luxembourg.
- If you’re Asia-based or want Asia access and English-speaking environment: Singapore.
- If your life is anchored in the EU and you want EU-compliant wrappers: Luxembourg/Monaco.
- If you’re MENA/India/Africa focused and want proximity: UAE (DIFC/ADGM).
- If you need dedicated trust/foundation ecosystems: Liechtenstein, Channel Islands, Cayman.
Sometimes the answer is “both”: custody in Switzerland for global diversification plus a Singapore account for Asia execution and timezone coverage.
A 12-Week Action Plan to Qualify
Week 1–2: Define objectives and constraints
- Why the account? Investment goals, currencies, lending needs
- Clarify tax residency now, not later
- Decide on personal vs. entity account(s)
Week 2–3: Shortlist jurisdictions and banks
- Match your nationality, industry, and AUM to receptive centers
- Pre-screen with an EAM or introducer if helpful
Week 3–5: Build the KYC/SOW pack
- Draft a 2–3 page narrative summary
- Gather evidence: SPAs, statements, tax returns, company docs
- Get certifications/apostilles where needed
Week 5–6: Submit and engage
- File a clean application. Anticipate clarifications and prepare answers
- Schedule the compliance interview. Rehearse your timeline and facts
Week 6–9: Clear follow-ups
- Provide additional documents quickly
- Align your investment mandate and understand fees
- Prepare initial funding path with source-of-funds proof
Week 9–12: Open, fund, and implement
- Complete e-banking and security setup
- Seed the account; confirm credit of funds and any additional checks
- Start investment or treasury operations
FAQs Clients Quietly Worry About
- Will the bank call my employer or counterparties? Rarely, and typically only with your consent. They rely on documents, not cold calls.
- Can I keep multiple tax residencies? You might, but you must disclose them accurately. CRS reporting will follow your self-certifications and the bank’s assessment.
- Can I use nominee directors/shareholders? Banks prefer transparent UBOs. If you use nominees, be ready with notarized declarations and professional administration.
- Will I get rejected if I say I have crypto? Not automatically. Provide a complete, auditable trail and tax reporting. Some banks still won’t accept it; others will with limits.
- Do I have to invest with the bank? Often yes, at least partially. Pure custody is harder below USD 2–5m.
What “Good” Looks Like to a Private Bank
When I sit with compliance teams, the files that glide through share these traits:
- A clear, chronological SOW, consistent with documents and public records
- Reasonable AUM for the bank tier, with willingness to engage on investments
- Simple structures, administered by reputable firms, with transparent UBOs
- Clean tax story with supporting filings and CRS/FATCA forms prepared
- Responsive client and advisor team, quick to provide clarifications
- Thoughtful, realistic investment policy and an RM who wants the relationship
None of this requires you to be a billionaire. It requires clarity, preparation, and choosing the right bank for your profile.
Final Thoughts: Qualify by Reducing Friction
The biggest unlock is not a clever structure—it’s reducing friction. Present a straightforward profile, assemble a quality document package, and pick a bank aligned with your nationality, industry, and asset level. If you need the reach of a larger platform, consider starting with an EAM to bypass common roadblocks, especially if you’re a US person or have nuanced wealth origins.
Private banking offshore is attainable for well-prepared clients with USD 1–5m+ to place, and it becomes progressively easier as your documentation and relationships deepen. Build a credible story, meet the bank halfway on profitability, and keep the relationship tidy. That’s how you qualify—and stay qualified—for the long term.
