Insurance float

What is insurance float?

Insurance float is the pool of money an insurer holds because premiums arrive before claims are paid. When a customer pays a one-year health or motor premium, the insurer keeps that money until claims under the policy are settled, which can be weeks for a hospital bill or years for a court-decided third party injury claim. In between, the insurer invests the money and earns a return on it.

Float is not shareholders' money. It belongs, in economic terms, to policyholders and claimants. But while it is held, the investment income it generates belongs to the insurer. The term is used mostly for general insurance and reinsurance. In life insurance, the equivalent pool is policyholders' funds backing long-term reserves, which is far larger and mostly earmarked for policyholder benefits.

How float arises and is measured

Float is roughly equal to:

Float = unearned premium reserve + outstanding claims reserves (including IBNR) minus premiums receivable and amounts due from reinsurers and other offsets

The two big sources are:

• Unearned premium: premium received for cover that has not yet been provided. A one-year policy sold on 1 January has half its premium unearned on 30 June.
• Claims reserves: money set aside for claims that have happened but are not yet paid, including reported claims still being settled and IBNR. Long-tail lines such as motor third party and liability generate the most float, because claims take longest to pay.

Worked example (illustrative numbers)

A general insurer earns ₹1,000 crore of net premium a year and runs a combined ratio of 104%, so it loses ₹40 crore on underwriting. On average it holds ₹1,500 crore of float, invested at 7.5%.

• Investment income on float: 1,500 × 7.5% = ₹112.5 crore
• Underwriting result: minus ₹40 crore
• Result before tax and before income on shareholders' capital: ₹72.5 crore profit

The float effectively costs the insurer 40 ÷ 1,500 = 2.7% a year, less than it earns by investing it. If the combined ratio rose to 110%, the underwriting loss of ₹100 crore would nearly wipe out the investment income.

Float in the Indian market

Indian general insurers depend heavily on float income. The IRDAI Annual Report 2024-25 shows the non-life industry with an underwriting loss of ₹30,276 crore in 2024-25 but investment income of ₹48,112 crore, giving profit after tax of ₹13,154 crore. Total investments of general insurers (including standalone health and specialised insurers) were ₹5.24 lakh crore at 31 March 2025, and of reinsurers ₹1.41 lakh crore. Life insurers' investments were ₹67.79 lakh crore.

Insurers must invest these funds within the pattern of investment set by the IRDAI (Actuarial, Finance and Investment Functions of Insurers) Regulations, 2024, with limits on asset classes and a large share in government securities.

What insurance float means for distribution

• It explains aggressive pricing. When interest rates are high, insurers can accept underwriting losses in pursuit of premium growth, because float income covers them. When rates fall, pressure on pricing, commission and partner payouts rises.
• Long-tail business is valued for float. Motor third party and commercial liability bring float but also reserve uncertainty. Insurers weigh both when setting appetite for dealer and broker portfolios.
• Payment speed matters. Delays in collecting premium from partners reduce float. Insurers track premium receivables from intermediaries and may limit credit to partners who remit late.
• Do not confuse float with profit. A growing float with a rising combined ratio is not a sign of health. Distribution leaders should look at underwriting results by channel, not only at premium growth.
