SAO PAULO, March 30 (Reuters) - Brazil's President Luiz Inacio Lula da Silva and Senator Flavio Bolsonaro are seen tied in a simulated run-off for this year's presidential election, a BTG Pactual/Nexus poll showed on Monday.
FIRST ROUND
Leftist Lula would take between 39% and 42% of the vote in three simulated first-round scenarios with different opponents.
Right-wing challenger Flavio Bolsonaro, meanwhile, is seen taking between 38% and 39% in the same scenarios.
RUN-OFF
Lula and Flavio Bolsonaro are seen tied at 46% in a potential run-off, the poll showed.
About 7% of respondents said they would vote for neither of the candidates.
ADDITIONAL CONTEXT
Markets have tracked polls closely since imprisoned former President Jair Bolsonaro's endorsement of his son Flavio sent Brazil's currency and equities sliding in December.
The 80-year-old Lula, who defeated the elder Bolsonaro in 2022, will seek a fourth non-consecutive term as president.
In Brazil, if no candidate gets more than 50% of valid votes, the two frontrunners go to a second-round vote, which has happened in every election since 2002.
Nexus surveyed 2,006 people between March 27-29. The poll has a margin of error of 2 percentage points in either direction.
