STOCKHOLM, July 16 (Reuters) - Swedish banking group SEB reported a second-quarter net profit that beat market expectations on Tuesday as slowing interest income momentum was considerably offset by other revenue streams and stood by its cost outlook for the full year.

The bank said in a statement that net profit dipped to 9.42 billion Swedish crowns ($887.7 million) from a year-ago 9.77 billion, beating the 8.74 billion forecast in a poll of estimates collected by LSEG. ($1 = 10.6114 Swedish crowns) (Reporting by Niklas Pollard, editing by Essi Lehto)
