Brazil President Lula polls at 46% and Flavio Bolsonaro at 44% in runoff, according to Datafolha poll

A two-point margin sits well inside the error bands Datafolha has carried in past cycles, and prior runoffs in the region have tightened considerably between rounds, so the signal here is a competitive race rather than a settled outcome. The relevant distinction is between the incumbent-left path, where markets price continued primary deficits and pressure on the central bank, and the challenger-right path, where the typical pattern is an initial relief rally in the currency and a flattening of the local curve on spending-cut expectations. Polls of this kind have tended to matter most through the fiscal channel, with swaps steepening when left-leaning outcomes firm and compressing when market-friendly candidates gain. Worth observing are whether subsequent surveys confirm the trend, how campaign fiscal proposals evolve, and any signal on central bank autonomy, which has been the recurring flashpoint.
