Viewing insurance float as a pure contradiction between source of capital and liability is an oversimplification that causes us to miss the trade. It is a contingent liability that can be invested in, not a sum of free money; failing to understand this leads to errors in position sizing. In France, under the supervision of the ACPR, any underestimation of technical reserves can lead to regulatory sanctions and invalidation of the business model, as shown by the example of some small mutual insurers who underestimated their climate risks. The trigger for an insurer is not the float itself, but the ability to manage both its assets and liabilities simultaneously with constant regulatory vigilance.
