Stress testing has been a successful crisis response tool to provide insight into bank capitalisation. As countries emerge from the financial crisis, stress testing is becoming part of banks’ own risk management as well as part of the toolkit of bank supervisors. This course will cover the history, the main policy issues and the tools needed to address them. We will draw from the European and the US, from private and public sector experience.

Following the Global Crisis the focus has been on how to make banks safer. Capital and liquidity requirements have been tightened, but attention now needs to shift to corporate governance and risk culture. This column argues that in opaque organisations, formal risk-appetite frameworks can provide a pre-commitment mechanism that tightens risk governance, but a focus on the wider risk culture is also important.

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.

Risk forecasting is central to financial regulations, risk management, and macroprudential policy. This column raises concerns about the reliance on risk forecasting, since risk forecast models have high levels of model risk – especially when the models are needed the most, during crises. Policymakers should be wary of relying solely on such models. Formal model-risk analysis should be a part of the regulatory design process.

Earlier this week, much of Southeast Asia was stunned by an earthquake that for a moment brought back memories of the devastating tsunami of 2004. The cost of such natural disasters has been on the rise in recent years due to an increase in the number of people living and working in high-risk areas. This column explores some of the reasons behind this increase.

Financial risk models have been widely criticised for both theoretical and practical failures, especially during the recent financial crisis. In the second of two columns, the authors outline why the shortcomings of risk models matter before making suggestions for how the financial industry and supervisors should use models in practice.

There is a strong consensus that banks had insufficient reserves set aside for a rainy day and that they should be required to hold more capital. This column says we should differentiate institutions less by what they are called and more by how they are funded. Encouraging individual risks to flow to those who can absorb them would make the system safer and introduce new players with risk capacities.
