To Brazil, where voters head to the polls this weekend to elect a new president. However, the debate in the run-up to the election seems to have only added uncertainty to the country's already fragile economy. Paulo Cabral has more from Sao Paulo. 

As Brazil continues the struggle to leave its economic crisis behind, the business community is closely following the coming presidential election. The uncertainties ahead have already brought instability to the currency and stock markets in recent weeks. But the long-term question -- is whether the new government will put the country back on track for economic growth.

This consultant lays out what he sees as the main expectations of market agents to reach that goal.

EDUARDO VELHO CHIEF ECONOMIST, GO ASSOCIATES "A commitment to economic stability, by keeping inflation and government expenses in check. And commitment to keeping a floating exchanging rate and to pushing a reform agenda. So, the market needs to know if the next president will have an independent economic team to do this or if there will be much government interference. And also whether the next president will have the political support he needs to push with the pension system reform."

The two leading candidates both say the country's pension system is in need of reform. But former Paulo mayor Fernando Haddad and his leftist Workers Party - with a strong trade union base - has been reluctant to commit to specific measures, like setting a minimum age for retirement.

Among market agents, there's a clear preference for the far-right candidate, former army captain Jair Bolsonaro - mainly because of the pro-market economist serving as his key adviser, Paulo Guedes. Bolsonaro often says he's not prepared to discuss the economy when questioned -- and defers to the man he says would be his "super minister" if elected.

But most analysts say some sort of reform is inevitable - and some say a left-winger may be in better position to get it done.

ANDRE PERFEITO CHIEF ECONOMIST, SPINELLI BROKERAGE "They can do the reforms with much more easy than a right-wing candidate. It's harder for someone like Bolsonaro or Alckmin to fight against the corporations, the trade unions, it's more difficult Sounds like easier for someone like Haddad or Ciro Gomes to do the that. But that's my opinion, the general opinion of the market is not this one. They want someone very committed with the reform."
