Funds withheld reinsurance is a collateral mechanism under which the cedant physically retains ceded premium that would otherwise be remitted to the reinsurer, treating the withheld funds as a liability owed to the reinsurer but available to satisfy the cedant’s recoverable against the reinsurer. It is the simplest and oldest form of reinsurance collateral.

Under a funds withheld arrangement, the cedant accounts for ceded premium but does not remit cash to the reinsurer. Instead, the cedant records a ‘funds withheld’ liability on its balance sheet equal to the premium not remitted, and pays interest to the reinsurer at a contractual rate. Claims falling due from the reinsurer are settled by debit to the funds withheld balance.
The arrangement effectively converts the cedant’s reinsurance recoverable into a netting arrangement against an offsetting payable, eliminating counterparty credit risk on the funds-withheld portion of the recoverable.
Funds withheld is recognised under Solvency II as a credit risk mitigant in the same manner as other collateral, with the requirement that the netting is legally effective in the relevant jurisdictions and that the cedant has clear contractual right to set off the recoverable against the payable.
For IFRS 17 the funds withheld balance is reported as part of the reinsurance liability with appropriate disclosure of the offsetting reinsurance asset.
Funds withheld is most commonly used in long-tail casualty quota share treaties where the reinsurer’s exposure runs off over many years and the cedant has a clear interest in retaining the cash to fund expected claims. It is also used by reinsurers writing into jurisdictions where they are not admitted, as a substitute for or supplement to trust or LOC collateral.
The interest rate paid on the funds withheld balance is a key commercial point. Where the rate is below the cedant’s investment yield, the cedant earns a positive carry; where it is above, the reinsurer effectively earns enhanced investment income.
Funds withheld can introduce its own complexity: dispute over the appropriate rate, the timing of withholding, the application of withholding tax on interest, and the treatment on insurer insolvency. Modern funds-withheld arrangements are usually documented in detail to manage these issues.
An illustrative example: a UK casualty quota share treaty cedes £30m of premium with a 30 per cent commission, leaving net premium of £21m. Rather than remit the £21m to the reinsurer, the cedant withholds the funds, recognises a £21m liability and pays the reinsurer interest at SONIA + 100 basis points on the balance. Claim recoveries are debited to the balance as they arise.
