Abstract

[eng] This article examines the emergence and evolution of the “ Too-Big-To-Fail” (TBTF) doctrine based on various case studies, identifying moral hazard as the cause for externalities. It examines the role of TBTF within the recent financial crisis with regard to its contribution to and appearance in the crisis. In drawing lessons from the current crisis, a broader concept of systemic relevance is developed building on bank characteristics beyond sheer size. Referred to as “ Systemically Important Financial Institutions” by the Financial Stability Board, it is argued that these banks should be regulated rather than downsized or broken up considering the advantages of having large diversified global banks. The article evaluates FSB’s proposed regulatory measures, including capital surcharges, resolution regimes, enhanced supervision and improved core financial infrastructure, and identifies resolution regimes as the most efficient mechanisms to counter TBTF. If designed appropriately, such resolution regimes could convert TBTF into TBDF, or “ Too Big for Disorderly Failure”. Finally, the article warns that in reaching a new equilibrium in the financial system, unintended consequences such as concentration, competitive distortion and regulatory arbitrage have to be taken into account. . Classification JEL : G21, G28, E51. [fre] Cet article examine l’apparition et l’évolution de la doctrine too big to fail (TBTF) («trop grand pour faire faillite » ) à la lumière de plusieurs études de cas et identifie l’aléa moral comme cause d’externalités. Il analyse le rôle joué par la doctrine TBTF dans la récente crise financière et se penche sur son apparition et sa participation à ladite crise. Si l’on tire les conséquences de la crise, le concept élargi d’importance systémique se nourrit d’autres caractéristiques que la taille des banques. Au vu des avantages que présentent les grandes banques globales diversifiées, ces «institutions financières d’importance systémique » (IFIS), comme les appelle le Conseil de stabilité financière, devraient faire l’objet de réglementations plutôt que se voir réduites ou démantelées. L’article propose une analyse des mesures réglementaires proposées par le CSF, notamment les surcharges en capital, le renforcement du contrôle, l’amélioration de l’infrastructure financière clé et les régimes de résolution, ce dernier mécanisme étant le plus efficient pour limiter les TBTF. Bien conçus, ces régimes de résolution pourraient convertir les TBTF en TBDF (too big for disorderly failure), des établissements trop grands pour une faillite chaotique. Enfin l’article souligne que pour parvenir à un nouvel équilibre du système financier, il faut tenir compte des conséquences involontaires telles que la concentration, la distorsion de la concurrence et l’arbitrage réglementaire. .
