A segregated portfolio company, or SPC, is a single legal entity that can create separate portfolios, each with its own assets and liabilities. By law, creditors of one portfolio cannot reach the assets of another, so different strategies, investor classes or asset pools can sit under one company without sharing risk.

The Cayman Islands provides for SPCs in its Companies Act, and the British Virgin Islands permits them with approval from its Financial Services Commission. This page explains who uses them, what regulation can apply and how banking works.

Short answer

Is each portfolio a separate company?

No. Portfolios are not separate legal persons, but the law ring-fences their assets and liabilities from each other.

  • Is a Cayman SPC regulated: Forming one is a registry matter, but an SPC operating as a fund or insurer is usually regulated by the Cayman Islands Monetary Authority.
  • Can a BVI company be an SPC: Yes, with approval from the BVI Financial Services Commission, typically for regulated funds or insurance.
  • Are the owners private: Directors, managers and beneficial owners go through due diligence and are disclosed where the law requires. An SPC is not an anonymity tool.

How segregation works

The SPC has one board of directors and one registration, but each portfolio keeps its own books, bank or custody records and contracts. Agreements must state which portfolio they bind. When this discipline is followed, a loss or claim in one portfolio stays within that portfolio.

Segregation only protects what is clearly allocated. Poor record keeping, mixed accounts or contracts that do not name the portfolio can weaken it.

Who uses an SPC

Investment funds with several strategies, managers running separate investor classes, insurance and reinsurance programmes, and proprietary trading or treasury groups that want to keep activities apart all use SPCs. Running one entity with many portfolios can cost less than forming and administering several companies.

The structure suits genuine portfolio separation. It is not a way to hide owners, and all directors, managers and investors are identified to licensed providers.

Regulation and licensing

An SPC that takes outside investors usually falls under fund rules, such as the Cayman Mutual Funds Act or Private Funds Act, or BVI investment business rules. That brings registration, audited accounts, valuation and AML duties. Insurance SPCs need an insurance licence.

Whether your plan needs a licence is a legal question for regulated counsel in the chosen jurisdiction.

Banking and custody

Institutions want to see how portfolios are separated in practice. Expect to explain who controls each portfolio, how investor money enters and leaves, and whether each portfolio has its own account or sub-account. Clear segregation in the account structure supports both the legal protection and the bank review.

We help prepare that file and point approved cases toward suitable institutions, working with licensed Cayman and BVI providers for formation and administration.

Running an SPC day to day

Good administration is what makes segregation hold up. Each portfolio should have its own name used consistently in contracts, invoices and account titles, its own ledger and its own valuation. Directors should minute which portfolio each decision concerns, and any assets that belong to the company as a whole, rather than a portfolio, should be recorded separately as general assets.

Most SPCs appoint a licensed administrator to keep records, calculate net asset values and handle investor subscriptions and redemptions. An auditor reviews the accounts each year, and regulated SPCs file returns with their supervisor.

Before forming one, it is worth comparing alternatives. A simple holding company with separate subsidiaries can give similar separation with more familiar banking, while a single fund with share classes may suit managers who do not need liability segregation. The right choice depends on investor expectations, the cost of administration and how institutions in your target markets view the structure.
