Richard Portes of the London Business School provides two good reasons why the EU's decision to adopt the French Banking Federation's proposal for rollovers with 10% interest costs is a serious mistake. It doubles the interest costs from 4-6% to 10% with 2% Greek GDP growth and makes debt servicing untenable. Portes says the real Brady Plan from the 1980's included a 35-40% bondholders haircut. Deals of this type have a precedent- in Mexico in 1988 and in Argentina in 2001 such bond exchanges were soon followed by deals that placed bondholder haricuts on creditors. The lesson from Latin America in the 1980's, says Portes, is that the burdens of servicing a debt of such proportions under onerous conditions only extinguishes the enterprise, investment and productive capabilities of the particular country trying to service that debt, making the debt even less serviceable. See the Wall Street Journal's editorial on this deal which it calls "The French Deception." The terms sound like Greek to the editors leaving a sense that French banks are only saying "gimme." The only benefit achieved may be putting off the problem and avoiding contagion to Portugal and Spain. Yet this is not that much of a benefit when one realizes that the problem has not gone away, and is likely to look much worse six or nine months from now....
