The Archbishop of York has called share traders who cashed in on falling prices "bank robbers and asset strippers".
The two most senior figures in the Church of England have condemned the behaviour of City traders, and questioned their value to society.
Dr John Sentamu told bankers in a speech the market system seems to have taken rules "from Alice in Wonderland".

It follows a speech to bankers by the Archbishop of York, Dr John Sentamu.
In it, he called share traders who cashed in on falling prices "bank robbers and asset strippers".
Capitalist mythology
In the piece which is due to be published in the magazine on Friday, Dr Williams attacks "unbridled capitalism" and defends the socialist theorist Karl Marx's critiques of the system.
He said it had become - much as Marx suggested - "a kind of mythology" in which people invested their faith, wrongly assuming it would work for the common good.
He urges that "short-selling" and some other financial practices be banned and wrote: "It is no use pretending that the financial world can maintain indefinitely the degree of exemption from scrutiny and regulation that it has got used to."
He accepts the need and desire for entrepreneurship but claims it is not the only way to create wealth. He denounces the notion that it is as a type of "fundamentalism".

"To a bystander like me, those who made £190m deliberately underselling the shares of HBOS, in spite of a very strong capital base, and drove it into the arms of Lloyds TSB, are clearly bank robbers and asset strippers," Dr Sentamu told the annual dinner of the Worshipful Company of International Bankers.
