看来还是金融危机闹的..........
The Irish economy expanded rapidly during the Celtic Tiger years (1994–2007) due to a low corporate tax rate, low ECB interest rates, and other factors.[vague] This led to an expansion of credit and included a property bubble which petered out in 2007. Irish banks, already over-exposed to the Irish property market, came under severe pressure in September 2008 due to the global financial crisis of 2007–2010.
Irish banks' foreign borrowings rose from €15bn to €110bn in 2004-08.[4] Much of this was borrowed on a three-month rollover basis to fund building projects that would not be sold for several years. When the properties could not be sold due to oversupply, the result was a classic asset–liability mismatch. At the time of the 2008 government bank guarantee the banks were said to be illiquid (but not insolvent) by €4bn, which turned out to be a huge underestimate.
