The humbling truth for Goldman is that US retail banking has become not only more reliable than investment banking, but more profitable. JPMorgan’s balance sheet is three times the size of Goldman’s and its retail banking arm made a 19% return on equity in the third quarter, compared with Goldman’s 11%
So Goldman is now trying to do the opposite of the old JPMorgan by adding banking to investment banking. JPMorgan’s former dilemma has not gone away — lending to blue-chip companies is not much of a moneymaker. A more tempting target is the high margins that banks make on credit cards. Hence Marcus, Goldman’s online lender (named after its founder Marcus Goldman), which offers loans to prime US consumers as an alternative to credit card debt. Marcus, which will launch next year in the UK, accounts for $12bn of the $28bn in new lending and financing planned by Goldman in the next three years as it diversifies.
