Fraser and other leaders also highlighted their strategy at Citi's first investor day for its services division held at the bank's New York headquarters. The unit houses Citi's treasury and trade solutions business, which processes $5 trillion of payments a day for multinational corporations across 180 countries. The bank's stock rose 1% on Tuesday afternoon. Investors have rewarded Fraser's sweeping turnaround efforts with an 18% boost to its stock this year. That is broadly in line with large rivals such as Bank of America and JPMorgan Chase, but outpaced a 6% gain for the broader KBW index of bank shares. Citi's net interest income, or the difference between what it earns on loans and pays out on deposits, is expected to be "modestly down" in the second quarter versus a year earlier, Mason said, excluding its markets unit.
