New Accounting Norms and Financial Regulation


The European banking activity depends on two sets of rules: Basel 2, that defines the need for regulatory capital, and the IFRS accounting norms (International Financial Reporting Standards). Both are significantly more complex than the former rules. Particularly, they are based on some mathematical models that have been proposed in the financial sector during the last twenty years: Value-at-Risk, its application to credit portfolio modeling and operational risks, the valuation of structured products, etc. Due to this sophistication, Risk Control and Financial departments, auditors, supervisors etc have to rely on some high-level « quant » teams to understand and apply these rules conveniently. Now, the latter rules are so important that no board of a bank will take an important decision without evaluating its consequences in accounting and regulatory terms. In parallel, the financial innovation has been fuelled by balance-sheet management and regulatory arbitrage. Finally, the accounting and regulatory rules are keys to understand the recent financial crisis and its implications.  This lecture will provide the basis of this accounting and regulatory culture, with a view towards practical applications and quantitative tools.
