Royal Bank of Canada analysts said the results pointed to a strong performance at BNP's trading arm and good cost control.
In securities trading, revenue edged down 1.8% but still performed better than some peers including Deutsche Bank (DBKGn.DE), which saw fixed-income trading decline by 17% in the first quarter.
At U.S. bank Goldman Sachs, first-quarter sales from fixed income, currency and commodities (FICC) trading, usually a bright spot, plunged 17% to $3.93 billion, while equity trading revenue sank 7% to $3.02 billion.
The first quarter net income, group share amounted to 4.44 billion euros, in line with expectations, and up from 1.84 billion a year earlier.
The first tranche of 2.5 billion euros was approved in March, a sign analysts deemed reassuring as it took place shortly after the collapse of Credit Suisse.
