New shares should be earmarked for residents to encourage the repatriation of private capital.

On the contrary, we should have learned from the crisis that financial markets need regulation, and that cross border capital flows are particularly dangerous.

And as the transatlantic trade imbalance widens further, ever larger capital flows will be needed to keep pushing the euro down.

Drawing a parallel from this national evolution, developing a financial architecture to perform similar functions in the international arena is essential. The rapid, and seemingly ceaseless globalization of private capital makes this more urgent by the day.

Borrowers, in turn, use these foreign loans to increase their accumulation of private assets held abroad, even as strict budget discipline and free capital movement implemented in line with IMF and World Bank structural adjustment programs have led to skyrocketing interest rates.
