A captive is an insurance company owned by the business or group it insures. It lets a large organisation retain some of its own risk, while still buying reinsurance above it. In Australia, a captive that carries on insurance business is authorised and supervised by APRA. Claims are handled in-house, by a TPA or by a fronting insurer.

Key takeaways

A captive is an insurer owned by the organisation it insures, set up to retain and manage that organisation's own risks.
APRA's prudential definitions name two captive categories: association captives (Category D) and sole parent captives (Category E).
Captives can be single parent, group or association owned, or cells within a protected cell company.
According to Insurance Business Asia, Singapore's regulator consulted in July 2026 on a protected cell company framework that would include captives.
Claims inside a captive still need a clear owner, a record the captive's board can rely on and, often, a TPA.

What is a captive insurance company?

A captive insurance company is an insurer owned by the organisation, or group of organisations, whose risks it insures. Instead of buying all its cover from the market, the owner insures part of its own risk through the captive. The captive usually buys reinsurance for large losses above what it can retain.

APRA's definitions describe the idea precisely. According to its prudential standard GPS 001, a corporate captive is an insurer that is "owned by a single company or a group of related bodies corporate" and "exists for the purpose of underwriting risks of the parent company or members of a group".

A captive is a real insurer, not just a fund. It holds capital, issues policies and pays claims. That separates it from simple self-insurance, where an organisation just pays its own losses, and from a discretionary mutual fund. The captive, self or mutual sets the three side by side.

What types of captive are there?

The main types are single parent captives, owned by one company or group; association captives, owned by members of an industry or professional body; group captives, owned by several unrelated businesses; and protected cell captives, where an owner rents a separate cell in a shared company. Each suits a different size and kind of owner.

Single parent (sole parent) captive. Owned by: One company or group of related companies; Typical user: Large corporates with predictable losses.
Association captive. Owned by: An industry or professional association, or its members; Typical user: Members of one industry or profession.
Group captive. Owned by: Several unrelated businesses; Typical user: Mid-sized firms sharing a programme.
Protected cell or rent-a-captive. Owned by: A cell owner, inside a company run by a sponsor; Typical user: Organisations too small for their own captive.

APRA's categories reflect the first two. In GPS 001, Category D insurers are "often referred to as 'association captives'", and Category E insurers are "often referred to as 'sole parent captives'". Cell structures are offered in some overseas domiciles rather than under Australian law.

How are captives regulated in Australia and New Zealand?

In Australia, a captive that carries on general insurance business must be authorised by APRA. APRA's prudential definitions recognise association and sole parent captives as categories of general insurer. In New Zealand, insurers, captives included, are licensed by the Reserve Bank. Some Australian groups instead place captives in overseas domiciles.

APRA's GPS 001 defines Category D and Category E insurers, and separately describes insurance group captives that reinsure an insurance group's own risks. As a result, a captive in Australia sits inside the same prudential framework as other general insurers, though its business is limited to its owners' risks.

Overseas domiciles remain common. Singapore, for example, already hosts many captives. According to Insurance Business Asia, the Monetary Authority of Singapore consulted from July 2026 on a protected cell company framework that would include captive insurance. Each domicile has its own rules on capital, governance and reporting.

The regulatory position changes over time. So any organisation considering a captive should take current advice on authorisation, tax and domicile rather than relying on older guidance.

Why do organisations set up a captive?

Organisations set up captives to cut the long-run cost of risks they understand well, and to get cover the market will not offer at a sensible price. Captives also give direct access to reinsurance. Against that, a captive needs capital, governance, management and enough premium to justify them.

Cost is the usual starting point. A large organisation with a good loss record may pay the market for losses it could fund itself. A captive keeps that premium, and any underwriting profit, inside the group.

Availability is the second reason. When the market withdraws from a risk, such as some liability or property exposures, a captive can provide cover the owner cannot buy elsewhere.

The costs are real. A captive needs capital, a board, a manager, auditors and actuaries. Losses can exceed what was expected. So captives generally suit organisations with large, stable premium spend and the appetite to manage an insurer.

How are claims handled inside a captive?

Claims in a captive are handled in one of three ways: by the parent's own claims or risk team, by a TPA appointed by the captive, or by a fronting insurer that issues the policy and handles claims before passing the risk to the captive. Whichever model is used, the captive's board needs a reliable record of every claim.

The fronting model is common where a licensed local insurer must issue the policy. The fronting insurer handles claims under its own processes and recovers the cost from the captive through reinsurance. In that model, the owner sees claims through the fronting insurer's reports.

A TPA model gives the owner more control. The captive appoints a third-party administrator to handle claims, and sets its own service standards. Meanwhile, an in-house model suits a parent with an existing claims or risk team, often one that already manages self-insured claims.

Records matter in every model. The captive's board, auditors, reinsurers and regulator all rely on claims data: reserves, payments, recoveries and open claims.

Frequently asked questions

What is a captive insurance company?

A captive insurance company is an insurer owned by the organisation, or group, whose risks it insures. It lets the owner retain part of its own risk and keep the premium for that risk, while buying reinsurance for large losses. It holds capital, issues policies and pays claims like other insurers.

Are captives legal in Australia?

Yes. APRA's prudential definitions recognise captives as categories of general insurer: association captives, owned by members of an industry or professional body, and sole parent captives, owned by one company or group. A captive carrying on insurance business in Australia needs APRA authorisation. Some Australian groups use overseas domiciles instead.

How big does a company need to be for a captive?

There is no fixed threshold. A captive needs enough premium to justify its capital, management, audit and actuarial costs, so single parent captives generally suit large organisations with significant, stable insurance spend. Smaller organisations sometimes use a cell in a protected cell company or join a group or association captive instead.

Who handles claims for a captive?

Claims for a captive are handled by the owner's own claims or risk team, by a third-party administrator appointed by the captive, or by a fronting insurer that issues the policy and handles claims before passing the risk to the captive. The captive's board needs a reliable record of every claim either way.

What is a protected cell captive?

A protected cell captive is a cell inside a protected cell company, which a sponsor runs and rents to several owners. Each owner's assets and liabilities sit in its own cell, legally separated from the others. This lets organisations too small for their own captive use one, in domiciles whose law allows cells.
