RIO DE JANEIRO, Sept 23 (Reuters) - The Brazilian real weakened past the psychologically key level of 2.4 per dollar on Tuesday for the first time since mid-February as anxiety about the outcome of the October presidential vote left investors jittery, piling pressure on the central bank to support the currency.
The real briefly weakened to 2.4005 per dollar in the first minutes of trade as traders nervously awaited a raft of electoral polls due this week.
Investors fear President Dilma Rousseff, who they accuse of failing to keep inflation at bay while driving the economy into a recession, may gain ground in the surveys.
The currency later traded around the 2.4-per-dollar mark, as investors also feared its sharp weakening could prompt the central bank to intensify its intervention program to support the real, possibly by increasing the rollover pace of currency swaps that expire early next month.
