What it means
Captive funds take a few recognisable shapes. A bank or insurer may run in house funds sold only through its own advisers, a corporate may run a venture fund financed entirely from its own balance sheet, and a large group may run a treasury fund that invests nothing but group cash.
In every case the capital arrives because of the relationship, not because the fund won a competitive mandate. The commercial logic is control and cost.
Keeping the money in house means the fees stay inside the group, the mandate can be written to suit the parent's goals, and the parent sees the portfolio in full detail rather than through a quarterly report. The flip side is weaker external discipline.
A manager whose capital is guaranteed is not tested by investors who can walk away, so poor performance can persist for years and fees can drift above what an open market manager would charge. That is why regulators in several markets have pushed hard on whether in house funds sold to a bank's own customers are genuinely in those customers' best interests.
Corporate venture funds are the shape most non finance managers meet. The parent commits the capital and the fund invests in start ups that are strategically useful, so a win can be a technology or a partnership rather than a cash return.
That strategic motive is legitimate but it makes performance much harder to judge against a conventional fund. The nuance to watch is conflict of interest, especially where customers are involved.
Captive funds that only invest the parent's own money raise mainly governance questions, while captive funds sold to outside customers raise suitability questions as well, which is why the two are usually governed and reported differently.
In practice
Real-world examples.
Example
A regional bank runs five in house funds that its branch advisers recommend to retail customers. The fees stay within the group, but the compliance team has to document each year that the in house option was suitable and not simply the more profitable one for the bank.
Example
An industrial group sets up a captive venture fund with a $120,000,000 commitment from its own balance sheet to invest in automation start ups. Two investments have produced no financial gain yet but gave the group early access to technology it later rolled out across its factories.
Example
An insurer forms a captive asset manager to invest its own premium reserves. The arrangement cuts external management fees, and because the mandate is written in house the portfolio is matched precisely to the timing of expected claim payments.
Formula
Calculation
A captive fund has no single defining formula, so the figure that usually decides whether to run one is the cost of managing money in house against the cost of paying an outside manager.
Internal Saving = (External Fee Rate x Assets) - Internal Running Cost
Suppose a group has $600,000,000 to invest, an external manager would charge 0.60% a year, and running the captive team costs $2,100,000 a year in salaries, systems, custody and compliance.
External fee: 0.60% x $600,000,000 = $3,600,000.
Internal running cost: $2,100,000.
Annual saving: $3,600,000 - $2,100,000 = $1,500,000.
The break even size is where the internal cost equals the external fee: $2,100,000 / 0.60% = $350,000,000 of assets. Below that the captive costs the group more than it saves, which is the simplest test of whether the fund should exist at all. Note that the saving assumes equal investment performance, and a $600,000,000 portfolio underperforming by just 0.5% a year gives up $3,000,000, twice the fee saving.Case study
Seen in the real world.
Pelham Crest Group is a fictional financial services group created for this illustrative example. It ran six captive funds distributed only through its own advisers, and the funds held $2,400,000,000 of client money with an average charge of 1.15%.
A board review compared the captive range with equivalent funds available in the market. Four of the six had trailed comparable external funds over five years, and the fee was above the market average in every case. The review found no misconduct, only the slow drift that comes from capital that never needs to be won. The board kept two funds where the group had genuine expertise, closed or merged the rest, and opened the adviser platform to external funds alongside the remaining in house ones.
The illustrative moral is that captive capital removes the feedback loop that keeps managers sharp. Pelham Crest replaced the missing market pressure with a formal annual comparison against outside alternatives.
Watch out
Common mistakes.
- Assuming a captive fund must be cheaper for investors, when the absence of competition often lets fees sit above comparable market funds.
- Judging a corporate venture captive on financial return alone, ignoring the strategic access that was the reason for setting it up.
- Confusing a captive fund with a captive insurance company, which is a related but separate structure used to insure the parent's own risks.
Questions
People also ask.
Who invests in a captive fund?
Either the parent organisation itself, or customers of the parent who are offered the fund through the group's own distribution rather than choosing it on the open market.
Is a captive fund the same as an in house fund?
In everyday use yes, although captive carries the stronger sense that the capital has nowhere else to go.
How should a captive fund be governed?
With an independent comparison against external alternatives at least annually, clear conflict of interest disclosure, and performance reported against the same benchmarks an outside manager would be held to.
