Brazil's economy has stumbled badly, but some analysts say upcoming elections and fresh polls showing rising dissatisfaction with the government could herald a change.
"The consensus is still that (President) Dilma Rousseff will win reelection" when the country votes on October 5, Tony Volpon, strategist for Latin America at Nomura, told CNBC. "But the government favorability ratings have been dropping like a stone. The latest poll numbers put that at 31 percent," he added.
Volpon believes the current government's policies have done "real damage" to some sectors of the economy, citing in particular the negative effects on the energy sector of refusing to allow gasoline and electricity prices to rise in an effort to control inflation.
