Goldman Sachs is building an in-house bank to lend money to wealthy people and companies, in a significant shift that underlines the harsh business climate facing Wall Street since the financial crisis.
The New York securities firm, known for its aggressive trading and big corporate deal-making, is ramping up its activities to become a private bank to serve wealthy customers around the world. The new unit will also lend more directly to corporations, some of whom already make investments and do business with Goldman. Executives have set a goal of $100 billion in loans, up from $12 billion at the end of March.
Ever since the financial crisis, so-called "casino banking" has been a very unpopular area to be in. The actual practice itself was frequently condemened, for causing unsustainable booms in food and  oil prices , as well as leading to the sort of attitude which caused the crash, where complex financial instruments were traded with little regard to fundamentals causing spiralling valuations which eventually got out of control.
But as well as casino banking being unpopular for what it is, it's unpopular for its relationship to regular banking. The idea is similar to that of "too big to fail", but the fear is that casino banks which also take consumer deposits are thus underwritten by the taxpayer, in the form of deposit insurance. It is for this reason that there are calls, in both Britain and the US, to split the former from the latter, or to allow banks to gamble, but not with customers' money. This latter requirement, the Volcker Rule, is what JP Morgan is suspected to have been bending in their disastrous "London Whale" trade.
Goldman Sachs' private bank is unlikely to fall on the retail side of any such divide, however. It's customers' deposits will be well in excess of the amount covered by insurance, so there will be little incentive for it to hamstring its activities. But its a long way to go to rehabilitate the Vampire Squid.
