Efficiency ratio for the quarter improved to 58 percent from 60 percent in the previous year period. A decline in efficiency ratio indicates a rise in profitability.

Citi chief executive officer Michael Corbat said, "The momentum we saw across many of our businesses towards the end of last year carried into the first quarter, resulting in significantly better overall performance than a year ago. Revenues increased in both our consumer and institutional lines of business, most notably in areas where we have been investing such as Equities, U.S. Cards and Mexico. We grew loans and deposits and achieved an efficiency ratio of just under 58%, an ROA of 91bps and a ROTCE ex-DTA of over 10%, showing good progress towards achieving our near-term financial targets."
