Outsourced CIO for insurance companies: what it is, what it costs, and when a smaller carrier actually needs one

Two very different things share one name

A discretionary OCIO takes over the investment function. It sets the asset allocation within your policy, hires and fires the managers (often its own funds), executes the trades, and reports back. You keep the policy statement and the fiduciary duty; the OCIO does everything underneath it. Fees are typically quoted in basis points on assets and, across the industry, land in the tens of basis points once underlying manager fees are counted.

A non-discretionary adviser, which is the model General Account Advisors uses, does not touch the portfolio. It sits on the insurer's side of the table: it writes or reviews the policy, evaluates the managers you already have, benchmarks the portfolio against peers, and reports to the finance committee in plain language. The managers keep managing. The adviser's only job is to make sure they are doing it well, at a fair price, inside a policy that fits the business. Fees are a fixed retainer rather than a percentage of assets.

Both are legitimate. The question is which problem you are solving.

When a discretionary OCIO fits an insurer

Discretion makes sense when an insurer has no internal investment staff at all, wants a single accountable party, is comfortable with the OCIO's manager lineup, and has enough assets that the basis-point fee buys a real team. For carriers above roughly a billion dollars of invested assets, or for a company going through a transition such as a merger or a management change, handing the keys to one firm can be the right call.

The trade-off is structural. An OCIO that places your assets in its own strategies is paid twice on the same dollar, and the firm evaluating the managers is also the firm being evaluated. That isn't a scandal; it's how the model works. It just means the board's independent check has moved outside the arrangement, and most small-carrier boards don't have one.

Where small and mid-size general accounts usually land

The NAIC's Capital Markets Bureau counted 2,415 U.S. insurers that outsourced investment management to unaffiliated firms at year-end 2024, 53% of all filers, and two-thirds of them held under $250 million in assets. Most of those companies are not buying a discretionary OCIO. They have one or two fixed-income managers on a separately managed account, a custodian, and a CFO who reviews the manager's quarterly deck. What they lack is the person a $5 billion carrier would have in-house: someone who knows what the mandate should cost, whether the duration is matched to the reserves, how much cash is really needed, and what the rating agency will ask.

That gap is what independent oversight fills, and it fills it for a fraction of what either an OCIO or a full-time investment officer would cost. A flat retainer on a $300 million general account works out to a few basis points. It also keeps the existing manager relationships intact, which matters to boards that chose those managers for good reasons.

Questions to ask any OCIO or adviser

• Who has discretion over asset allocation and manager selection, in writing?
• Does the firm or any affiliate earn revenue from the managers or funds it recommends? Ask for the total all-in cost in basis points, including underlying fund fees.
• How many insurance general accounts does the firm advise, and in what size range? Statutory accounting, RBC, and rating-agency capital models are not optional knowledge.
• Who presents to the finance committee, and how often? Will the same person be there next year?
• What happens to the portfolio if the relationship ends? Separately managed accounts transfer cleanly; proprietary fund structures often don't.
