Informative chart from The Economist, looking at exactly where funding is coming from for the various PIIGs bailouts.
The total €865 billion ($1.2 trillion) pot available for euro-area rescues is rather enormous. (Whether it will be sufficient to cope with Greece, Ireland and Portugal’s needs is yet to be determined).
The sources of all that cash include the European Financial Stability Facility, (€440 billion) primarily funded by Germany, France and Italy. The IMF can kick in up to €280 billion. America has also suggested she will lend €50 billion.>
