The real fell 0.3 percent to 2.2204 per dollar at 12:11 p.m. in Sao Paulo. Swap rates, a gauge of expectations for interest-rate moves, rose three basis points, or 0.03 percentage point, to 11.08 percent on the contract due in January 2017.
“There is always a negative reaction for the real when polls show Rousseff has a chance of being re-elected,” Reginaldo Galhardo, a foreign-exchange manager at Treviso Corretora de Cambio in Sao Paulo, said in a phone interview.
The real pared its rally this year to 6.5 percent, remaining the biggest among 24 emerging-market currencies. It declined today as a July 18-21 poll from Ibope indicated that backing for Rousseff for the October election slipped to 38 percent from 39 percent last month, still higher than the 22 percent support for Senator Aecio Neves. The survey has a margin of error of plus or minus 2 percentage points.
If no candidate has more votes than all other opponents combined, the two front-runners go against each other in a second vote. In a runoff between Rousseff and Neves, she would have a lead of 8 percentage points, the poll indicated. Datafolha and Sensus surveys last week showed Rousseff’s advantage over Neves in a second round was within the margins of error, making the outcome too close to call.
