Trading picked up early in the quarter after the Swiss National Bank shocked currency markets by scrapping a three-year-old cap on the Swiss franc without warning, causing the currency to soar against the euro. Revenue from trading fixed income, currencies and commodities (FICC) rose 5 percent to $4.07 billion, adjusted for the sale of businesses last year, including a physical commodities operation. The bank’s shares rose about 1 percent to $62.70 in premarket trading.
