(Adds details from quarterly report, updates shares)
July 13 (Reuters) - Citigroup Inc's quarterly profit topped Wall Street estimates on Friday, helped by strength in its consumer banking business in Mexico, North America and Asia.
The third-largest U.S. bank by assets, like its peers, also benefited from a cut in income tax rates and an expanding U.S. economy that fueled demand for loans.
Net income rose to $4.49 billion in the second quarter ended June 30, from $3.87 billion a year earlier, driven by a 14 percent jump in net income for its global consumer banking.
Pretax profit from continuing operations increased 5 percent.
Earnings per share rose to $1.63 from $1.28 and topped analysts' average estimate of $1.56, according to Thomson Reuters I/B/E/S.
The bank's provision for income tax fell by $351 million, following President Donald Trump's corporate tax rate cuts.
Buybacks reduced shares outstanding by 8 percent from a year earlier, further boosting earnings per share.
Revenue rose about 2 percent to $18.47 billion but came in slightly below the average expectation of $18.51 billion as revenue from its investment banking business fell 7 percent.
The bank's fixed income trading revenue fell 6 percent, while equity trading revenue rose 19 percent. Total markets and securities services revenue fell 1 percent.
Last month, Chief Financial Officer John Gerspach said he expected trading revenue to be "flattish" compared with a year earlier.
Through Thursday, Citigroup shares are down 7.9 percent for the year, compared with the 1 percent drop in the broader KBW Bank Index.
JPMorgan Chase & Co's quarterly profit topped Wall Street's expectations on Friday, as trading revenue came in much higher than expected and demand for loans increased on the back of a strengthening U.S. economy.
