Regulation of the global insurance industry, an emerging challenge in international finance, has two central objectives: strengthening the oversight of insurance companies designated ‘systemically important’; and designing a global capital standard for internationally active insurers. This column argues that it is a Herculean task because the business model of insurance is less globalised than other areas in finance; because global regulators have less experience of insurance than banking where global standards have been pursued for a quarter of a century; and because, as yet, there is limited research-based understanding of the insurance business and its interactions with the financial system and the real economy. But in the aftermath of the global financial crisis and the AIG disaster, regulators are under strong pressure to make progress.
