Borrowed billions spent in a few days
First, the borrowing itself is financially irrational. Based on the current government borrowing requirement for 2010 each of the two €750 million tranches of monies borrowed this week, over six and eight years respectively, will be spent in under 13 days. It is akin to taking a term loan out to go on a two-week summer holiday and the state is doing this on a continuous basis.
Second, the reason the free market is willing to lend such monies to Ireland, rather than impose realistic rates or not lend at all, is that the ECB is backstopping the borrowing by creating an artificial market for such EU government bonds.
