Brazil posted a primary budget surplus of 3.729 billion reais ($1.46 billion) in October, central bank data showed on Friday, breaking a string of five straight monthly deficits.

The primary budget had been expected to show a surplus of 3.5 billion reais in October, according to the median forecast of 13 analysts surveyed by Reuters.

In the first ten months of the year, the primary balance showed a deficit of 11.557 billion reais.

The government originally aimed for a primary surplus, which represents the public sector's excess revenue over expenditures before debt payments, of 99 billion reais or the equivalent of 1.9 percent of gross domestic product for full-year 2014.

The government now seeks a surplus of just 10 billion reais.

The country posted a primary deficit of 25.491 billion reais in September.
