I just stumbled upon an article from last March by Michael Lewis, in which he explains how thoroughly Irish banks screwed themselves:
A single bank, Anglo Irish, which, two years before, the Irish government had claimed was merely suffering from a “liquidity problem,” faced losses of up to 34 billion euros. To get some sense of how “34 billion euros” sounds to Irish ears, an American thinking in dollars needs to multiply it by roughly one hundred: $3.4 trillion. And that was for a single bank. As the sum total of loans made by Anglo Irish, most of it to Irish property developers, was only 72 billion euros, the bank had lost nearly half of every dollar it invested.
[W]hile Icelandic males used foreign money to conquer foreign places—trophy companies in Britain, chunks of Scandinavia—the Irish male used foreign money to conquer Ireland. Left alone in a dark room with a pile of money, the Irish decided what they really wanted to do with it was to buy Ireland. From one another. An Irish economist named Morgan Kelly, whose estimates of Irish bank losses have been the most prescient, made a back-of-the-envelope calculation that puts the losses of all Irish banks at roughly 106 billion euros. (Think $10 trillion.) At the rate money currently flows into the Irish treasury, Irish bank losses alone would absorb every penny of Irish taxes for at least the next three years.
Fascinating reading. Given its growth and prosperity ten years ago, it's staggering how a few dozen stupid people could have derailed the country entirely.
