Citigroup profits fell 12 percent in the second quarter compared to the same period a year before, the bank announced Monday. The US banking giant said it made $2.9 billion dollars for the quarter as a drop in revenues from Europe, the Middle East and North Africa restrained profits. “Our core businesses performed well in a difficult environment and are generating solid returns,” said Citi’s Chief Executive Officer Vikram Pandit. “We had strong growth in both loans and deposits, showed resilience in our markets-facing businesses, and saw record revenues in Transaction Services,” he said.
