After the European Bank Stress Tests
Alicia Damley submits:Underwhelming might be the best way to describe the results of the European bank stress tests and the market’s reaction to them. Paying heed to market demands, the Committee of European Banking Supervisors (CEBS) released informative details on the stress test assumptions, which reveal that the adverse scenarios were not particularly unpleasant. A key assumption underlying the value of the analysis is that, given the number of variables stressed, the interaction of the variables was consistent with economic reality. Overall, the adverse assumptions suggest that many conditions in Q1/2010 were already near the worst case scenario for most of the EU economies. This includes GDP growth, unemployment, sovereign credit risk, real estate price declines, and default and loss probabilities. Particularly problematic given market concerns about the amount of sovereign debt on European bank balance sheets was the scenario testing focused only on the bonds held for trading vs held to maturity. Simply put, Tier 1 ratio calculations increase both the risk weights attached to and the capital required to be held for government bonds which drop through AA-. The net effect is a rapid reduction the Tier 1 ratio unless new capital is raised since both the numerator and denominator move in opposite (adverse) directions. The modest decline in the Tier 1 ratio (110 bps), low estimated Tier 1 capital shortfall of €3.5 bn and corresponding low (7 out of 91) number of banks which failed are substantially attributable to this.Complete Story »
