💰 '''Insurance float''' is the pool of money that an [[Definition:Insurance carrier | insurance carrier]] holds between the time it collects [[Definition:Insurance premium | premiums]] from [[Definition:Policyholder | policyholders]] and the time it pays out [[Definition:Claims management | claims]]. Because premiums arrive up front while losses are settled weeks, months, or even years later, insurers temporarily control substantial funds that can be deployed in [[Definition:Investment portfolio | investment portfolios]] to generate income — a dynamic that Warren Buffett famously described as the economic engine behind Berkshire Hathaway's insurance operations.

📐 The size and duration of float vary by [[Definition:Line of business | line of business]]. A [[Definition:Workers' compensation insurance | workers' compensation]] or [[Definition:General liability insurance | general liability]] book, where [[Definition:Long-tail | long-tail]] claims can take years to resolve, produces float with a much longer investment runway than a [[Definition:Personal auto insurance | personal auto]] book, where claims settle in months. Insurers invest float in bonds, equities, real estate, and alternative assets, and the [[Definition:Investment income | investment income]] earned can be significant enough to allow a carrier to [[Definition:Underwriting | underwrite]] at a modest [[Definition:Underwriting loss | underwriting loss]] and still generate healthy overall returns. Managing this interplay between [[Definition:Combined ratio | combined ratio]] and investment yield is at the heart of insurance financial strategy.

⚠️ Float is only an advantage when obtained at low cost — meaning the premiums collected exceed, or only slightly trail, the eventual [[Definition:Loss | claims]] and [[Definition:Operating expense | expenses]] paid. If [[Definition:Loss ratio (L/R) | loss ratios]] spike, the cost of float rises and can erode the investment gains it was meant to produce. In a rising-interest-rate environment, float becomes even more valuable because reinvestment yields improve; conversely, prolonged low rates squeeze the strategy. For [[Definition:Insurtech | insurtechs]] and [[Definition:Managing general agent (MGA) | MGAs]] that do not carry risk on their own [[Definition:Balance sheet | balance sheets]], understanding float matters less from an investment standpoint but remains critical to grasping why their carrier partners make particular pricing and capacity decisions.
