Wall Street’s credit-derivatives traders, who before the financial crisis commanded $2 million of annual pay, are being replaced by machines as banks cut costs and heed new regulations. UBS, Switzerland’s biggest bank, fired its head of credit-default swaps index trading, David Gallers, last week, with no plan to fill the position, according to two people familiar with the matter. Instead, the bank replaced Gallers with computer algorithms that trade using mathematical models, said the people, who asked not to be identified because moves are private.
