Bolsonaro's first-round performance has strengthened the prospect of a competitive second round and generated a positive response in financial markets as investors assess the possibility of a change in Brazil's economic policy direction. Reuters reported that Bolsonaro received stronger support than some earlier polling had suggested.
The election has significant implications for Brazil's fiscal outlook. Investors are closely monitoring government spending, public debt and the credibility of efforts to maintain fiscal discipline as the next administration prepares to manage a large emerging-market economy.
A Bolsonaro victory could also produce a shift in Brazil's international economic relationships. The senator has positioned himself closer to US President Donald Trump and is expected to pursue stronger relations with Washington, contrasting with Lula's more critical approach to US trade and foreign policy.
The contest is therefore being watched beyond Brazil's domestic political environment. Changes in economic policy could influence the Brazilian real, government bonds, equities and foreign investment flows, while changes in trade policy could affect the country's relationships with the United States, China and other major partners.
Markets have already shown sensitivity to the political developments. Investors are assessing whether a potential change in government would lead to stronger fiscal controls or create new policy uncertainty during a period of elevated global borrowing costs.
Lula nevertheless remains a formidable contender. A Datafolha poll published before the first-round vote showed the incumbent leading Bolsonaro 48% to 45% in a simulated runoff, demonstrating the narrow margin separating the two candidates.
The runoff is expected to become increasingly focused on the economy, public finances and Brazil's international position. Businesses will also be assessing the candidates' approaches to investment, regulation and trade.
For investors, the election represents a major test of Brazil's policy direction. The final result will determine whether the country maintains its current economic course or enters a new phase of fiscal, trade and foreign-policy priorities. The runoff is therefore likely to remain a major driver of Brazilian financial-market sentiment through October.
