(Adds data on exports and imports, year-to-date surplus)
BRASILIA, Nov 1 (Reuters) - Brazil recorded a trade surplus of $2.346 billion in October, government data showed on Tuesday, the biggest surplus posted for that month since 2011, but narrower than the $3.8 billion surplus recorded in September.
The result was smaller than market expectations for a surplus of $2.7 billion, according to a Reuters poll.
Exports totaled $13.721 billion and imports $11.375 billion.
Economists in a weekly central bank poll expect a trade surplus of $48 billion in 2016, more than double last year's result after a severe recession curbed demand for imports.
Brazil's trade surplus so far this year has risen to $38.5 billion, more than three times larger than in the same period of 2015. A steady inflow of dollars has helped strengthen the Brazilian currency by more than 20 percent year-to-date. (Reporting by Cesar Raizer; Writing by Silvio Cascione; Editing by James Dalgleish)
