An offshore trust with no offshore bank account behind it is a document, not a working structure. Once a Cook Islands Trust or its underlying LLC is registered, the assets still need somewhere to sit, and “offshore bank” covers a wider range of institutions than most people expect. A licensed offshore bank, a private bank, a Swiss institution, and an electronic money institution each serve a different client profile, and picking the wrong one adds friction that a better match would have avoided.
Offshore Broker introduces clients to vetted offshore banking partners across licensed offshore banks, private banks, Swiss institutions, and digital asset providers. Our team is based in the Cook Islands, with direct experience inside the region’s private banking sector.
Licensed Offshore Banks
A licensed offshore bank in a jurisdiction like the Cook Islands, Nevis, or the Bahamas offers standard retail and business banking services, checking and savings accounts, wire transfers, multi-currency holding, aimed at international clients rather than local residents. Account opening typically requires proof of the underlying structure, source of funds documentation, and a minimum deposit that varies by institution but often starts in the low tens of thousands of dollars.
This is the default choice for the operating account beneath a Cook Islands Trust and LLC structure, since it is built specifically for the kind of client the trust already serves, and the account opening process is accustomed to reviewing trust and LLC documentation rather than treating it as unusual. Our guide to opening an offshore bank account covers the documentation checklist in detail.
Private Banks
Private banks sit a tier above standard offshore banks, offering investment management, credit facilities, and dedicated relationship managers alongside deposit accounts. Minimum relationship sizes are substantially higher, often starting at $1,000,000 or more in investable assets, and the onboarding process is more thorough, reflecting both the size of the relationship and the additional services on offer.
For a settlor whose offshore trust holds a significant securities portfolio rather than primarily cash, a private bank relationship inside the structure can combine custody, investment management, and banking in one place, rather than splitting those functions across separate providers. This tends to make sense once the trust’s asset base clears roughly $2,000,000 to $3,000,000; below that threshold, the added services rarely justify the higher minimums and fees.
Swiss Bank Accounts
Swiss banking carries a reputation for stability that predates most other offshore jurisdictions, built on a currency, legal system, and banking sector oriented toward long-term wealth preservation rather than short-term yield. A Swiss account held by a Cook Islands Trust’s underlying LLC adds a jurisdictional layer distinct from the Cook Islands itself, spreading exposure across two independent legal systems rather than concentrating everything in one.
Swiss institutions have tightened onboarding requirements considerably since the end of Swiss banking secrecy in its historical form, and account opening now involves the same source-of-funds and beneficial ownership scrutiny found elsewhere, sometimes more of it. What Switzerland still offers is currency diversification, a deep private banking tradition, and, for clients specifically interested in physical wealth preservation, access to allocated Swiss gold storage outside the banking system entirely. Full detail is in our guide to Swiss bank accounts.

Electronic Money Institutions
EMIs are a newer category, licensed to hold and move client funds without full banking licenses, and they have become a practical option for clients who need fast account opening, multi-currency support, and digital-first account management, including access to cryptocurrency rails that traditional offshore banks are often slower to offer. Onboarding is generally quicker than a licensed bank, sometimes days rather than weeks, though deposit protection and the range of services available are more limited than a full banking relationship.
EMIs suit clients who need an operational account moving quickly, particularly where a portion of the trust’s assets are held in cryptocurrency, while a more traditional offshore or private bank account holds the bulk of the underlying wealth. Few clients rely on an EMI as their sole banking relationship; most pair one with a licensed bank for the reasons above.
What Account Opening Actually Involves
Every category above runs through some version of the same due diligence process, though the depth varies. A bank will want certified copies of the trust deed or LLC formation documents, government identification for the settlor and any signatories, a source of funds narrative explaining where the assets originated, and often a reference letter from an existing bank. Structures involving a Cook Islands Trust and underlying LLC typically move faster through this process than a personal account application, since the trustee and registered agent can supply much of the documentation directly and banks accustomed to trust-owned entities know what to expect from the paperwork.
Timelines vary by institution and jurisdiction: a licensed offshore bank with an established relationship with the client’s trustee can often open an account in two to four weeks, a private bank relationship typically runs six to eight weeks given the added investment management onboarding, and an EMI can sometimes complete the process in days. Clients who assemble their documentation before the trust is even funded, rather than starting the banking search afterward, generally move through this process with the fewest delays.
Matching the Account to the Structure
The right choice depends on what the trust holds and how it needs to move. A straightforward Cook Islands Trust with an underlying LLC managing routine cash and investment activity is usually well served by a licensed offshore bank. A larger securities-heavy structure benefits from a private bank relationship. A client prioritizing jurisdictional diversification and long-term wealth preservation adds a Swiss account. A client who needs speed, multi-currency flexibility, or crypto access adds an EMI alongside a primary bank.
Most well-built structures end up using more than one of these, an operating account at a licensed offshore bank, a Swiss account for diversification, an EMI for specific transactional needs, rather than treating the decision as a single either-or choice. Our overview of the full offshore banking silo covers investment accounts and trust fund structures as well, and our guide to offshore asset protection places banking in context alongside the trust, LLC, and equity-stripping components of a complete plan.
