Cost of crash: $2,800,000,000,000

Autumn's market mayhem has left the world's financial institutions nursing losses of $2.8tn, the Bank of England said today, as it called for fundamental reform of the global banking system to prevent a repeat of turmoil "arguably" unprecedented since the outbreak of the first world war.
In its half-yearly health check of the City, the Bank said tougher regulation and constraints on lending would be needed as policymakers sought to learn lessons from the mistakes that have led to a systemic crisis unfolding over the past 15 months.

How much is that?

The Bank of England may have put the paper cost of the global crisis at a staggering $2.8 trillion, but how does one come to grips with such a sum? Think of it like this: it could pay for 46 bail-outs of the kind the Treasury handed to the banks RBS, HBOS group and Lloyds TSB; or pay off the last quarter's public debt 45 times. It is more than three times the sum of UK annual public spending, and also equivalent to the wealth of 100 Oleg Deripaskas - before the credit crunch anyway. It's equal to 138m bottles of 1947 Petrus Pomerol, the bankers' favourite vintage; or, if it's your turn in the coffee round, 773bn lattes - nearly 13,000 each for every UK citizen.
