IMF puts total cost of crisis at £7.1 trillion

Telegraph
"The staggering total is is equivalent to around a fifth of the entire globe's annual economic output and includes capital injections pumped into banks in order to prevent them from collapse, the cost of soaking up so-called toxic assets, guarantees over debt and liquidity support from central banks. Although much of the total may never be called on, the potential outlay still dwarfs any previous repair bill for the global economy."
