This spring, traders and analysts working deep in the global swaps markets began picking up peculiar readings: Hundreds of billions of dollars of trades by U.S. banks had seemingly vanished.
“We saw strange things in the data,” said Chris Barnes, a former swaps trader now with ClarusFT, a London-based data firm.
The vanishing of the trades was little noted outside a circle of specialists. But the implications were big. The missing transactions reflected an effort by some of the largest U.S. banks — including Goldman Sachs, JP Morgan Chase, Citigroup, Bank of America, and Morgan Stanley — to get around new regulations on derivatives enacted in the wake of the financial crisis, say current and former financial regulators.
