Corporate appetite for captive insurance is growing at a pace that even its proponents did not anticipate, as years of punishing market conditions and ballooning risk costs push companies of all sizes toward self-financing structures that were once the preserve of only the largest multinationals.
A sweeping report from Global Insurance Law Connect (GILC), drawing on insights from member firms across 20 jurisdictions, paints a picture of a sector in the midst of a structural shift.
More than 7,000 captives are now active worldwide, collectively writing in excess of $80 billion in premiums – figures that reflect not a passing trend but a fundamental rethinking of how corporations manage risk.
The roots of the current boom trace back to 2018, when the commercial insurance market began a prolonged hardening cycle that has yet to fully reverse. In Spain alone, captive demand has surged by an estimated 50% over the past five years.
Similar trajectories have played out across Australia, New Zealand, the US and Latin America, where corporates have grown weary of volatile pricing in lines such as cyber, environmental liability and catastrophe-exposed property.
What is striking is that the return of surplus capacity to the reinsurance market – global reinsurance capital has climbed back above $700 billion – has done little to slow the trend. Rather than unwinding their captive programs, companies are using the improved conditions to optimize retentions and redeploy capital within existing structures.
"We are witnessing a structural shift in corporate risk financing," said Gillian Davidson (pictured above), chair of GILC. "Captives are increasingly central to enterprise risk strategy."
The competition to attract captive formations has intensified. France, which enacted legislative reforms in 2023, has seen its domestic captive count rise from fewer than 10 to 23 within two years.
The UK is expected to follow with a government-backed captive insurance regime by summer 2027, a move that the London Market Group's Caroline Wagstaff has described as a way to "retain and attract corporate capital that might otherwise move offshore."
Yet the expansion is not without friction. Securing a fronting carrier – the licensed insurer that issues policies on behalf of a captive in jurisdictions where it is not admitted – can take four to five months, industry practitioners say, with pricing leverage tilted firmly in the fronting insurer's favor.

Collateral demands of 20% to 30% of premium compound the cost, particularly as captive programs push into newer territory such as cyber and medical stop-loss.
Regulatory scrutiny, too, is sharpening. The US Internal Revenue Service finalized regulations in 2024 that classified certain micro-captive transactions as listed transactions, targeting structures with loss ratios below 60% over a decade.
WTW has cautioned that the resulting compliance burden may deter new micro-captive formations. The National Association of Insurance Commissioners, meanwhile, adopted Actuarial Guideline 55 in 2025 to tighten asset adequacy testing for life reinsurance treaties involving captive insurers.
The GILC report's broader conclusion is one of cautious optimism: the captive sector's momentum shows no sign of stalling, but the risk landscape confronting captive owners is growing more complex in tandem with the opportunity.
