Private banking with a named relationship manager, not a ticket queue.
Built around trustee-administered and multi-layered ownership structures.
Banking, global markets and digital-asset custody under one regulated bank.
& Supervised
Fifteen islands, and a forty-year head start.
When lawyers and trustees talk about asset protection, the Cook Islands is usually the first name on the list. It was a pioneer of dedicated asset-protection trust legislation, and those laws have been tested in court repeatedly for decades.
The Cook Islands is self-governing in free association with New Zealand, with its own laws, courts and financial regulator. Banks are licensed under the Banking Act 2011 and supervised by the Financial Supervisory Commission.
In other words: the legal framework was designed for international wealth, and the bank was designed for that framework.
The Cook Islands exchanges account information under the OECD's Common Reporting Standard, and CSB reports US account holders under FATCA. This is about legal protection and diversification, not about hiding money from your tax authority.
How a Pacific nation built a financial centre on trust law.
Six dates that explain why trustees and family offices have banked here for decades.
Trusts Act
The International Trusts Act creates a legal basis for international trusts run by licensed local trustees.
Protection Rules
Amendments tighten creditor challenges and limit the weight of foreign court rulings.
CSB Founded

New Leadership
Joseph Horn-Smith becomes CEO of CSB after three years as COO.
A bank that chose to stay boring.
CSB doesn't make unsecured loans and doesn't speculate with its balance sheet. It keeps its liquidity mainly in highly rated developed-market government bonds, and reports a capital ratio well above Basel III requirements.
It's licensed for both domestic and international banking, and its shareholders, directors and managers are approved by the Financial Supervisory Commission. Clients are mostly high-net-worth individuals, trustees, family offices and asset managers.
The bank account is not the shield.
A lot of content online implies that a Cook Islands bank account protects your assets by itself. It doesn't. The legal protection comes from a Cook Islands trust that owns the assets, often through a company or LLC it controls.
CSB is where that structure keeps its money and investments: a regulated bank inside the same legal system as the trust, with decades of experience working with trustees.
Cook Islands Trust
Holds the assets under Cook Islands law, administered by a licensed local trustee.
Company or LLC
Optional holding entity owned by the trust, for flexibility in managing investments.
Account at CSB
Where the structure's cash, securities, metals and digital assets are banked and held in custody.
Built for serious wealth, not small savings.
CSB is a private bank, and it's priced and structured like one. For the situations below, few banks anywhere offer the same combination.
Asset Protection Trusts
The bank CSB was founded for: banking and custody for Cook Islands trusts, set up with and administered by a licensed trustee.
Core usePrivate Clients
Multi-currency accounts for individuals who want part of their wealth outside their home banking system, with a banker who knows them.
Holding Companies
Accounts for corporates, partnerships and foundations, including complex, multi-layered ownership structures.
Global Investing
Custody and execution for stocks, bonds and ETFs on major markets, plus fiduciary deposits placed with partner banks in Switzerland, Singapore and elsewhere.
Precious Metals
Buy, sell and store precious metals inside the same banking relationship, next to your cash and securities.
Digital-Asset Wealth
Bank-grade crypto custody with direct fiat rails, for clients who want digital assets inside a regulated private bank, not on an exchange.
NewWho it's for, and who shouldn't bother.
CSB is a private bank for substantial wealth. The bank's standard published minimum is USD 250,000; for clients we introduce, entry terms are agreed case by case.

✕ Not a fit if you
- Need an everyday account for frequent payments or an online business

Request your introduction
Before you request an introduction.
Do I need to travel to the Cook Islands?
No. CSB processes applications with certified documents and online identity verification. You're welcome to visit Rarotonga, but it's not required. Approval still depends on your profile and the bank's compliance review.
What is the minimum deposit?
The bank's standard published minimum is USD 250,000 or the equivalent in another currency. For clients introduced through our relationship, entry terms are agreed case by case, so tell us your situation and we'll tell you what's realistic.
Does a CSB account protect my assets from lawsuits?
Not by itself. Asset protection comes from a properly structured Cook Islands trust, set up well before any claim arises. CSB is the bank that structure uses. Courts in your home country can still act against you personally, so a qualified lawyer should design the trust.
Can Americans open an account?
CSB reports US account holders to the IRS under FATCA, and the Cook Islands trust is widely used in US asset-protection planning. US persons provide FATCA documentation, and US reporting obligations such as FBAR and Form 8938 still apply.
Is my money protected?
There is no government deposit insurance on CSB deposits. The bank's protection lies in its conservative model: no unsecured lending, no speculative investments, liquidity held mainly in highly rated government bonds, and a capital ratio well above Basel III. We still treat CSB as one part of a diversified setup.
Is this a secret or tax-free account?
No. The Cook Islands exchanges information under the OECD's Common Reporting Standard and CSB reports under FATCA, so your home tax authority can receive details of the account. You remain responsible for declaring it where you are tax resident.
Does CSB pay interest?
Interest is paid on fixed-term deposits above USD 500,000 or the equivalent. For smaller balances, CSB also offers fiduciary deposits with partner banks in Switzerland, Singapore and elsewhere.
How does the crypto custody work?
Digital assets are held in segregated vaults on the Fireblocks platform, with CSB as legal custodian and multi-approval controls on every transaction. Transfers are screened with Chainalysis and Travel Rule compliance, and fiat moves directly through your CSB account. Expect full source-of-funds checks on incoming crypto.
