巴西总统大选震动市场；ETF暴跌13%

Financial markets experienced a sharp reaction to the outcome of Brazil's presidential runoff, with the iShares MSCI Brazil ETF dropping 13 percent in a single session. The steep decline reflects investor anxiety surrounding the economic platform of President-elect Luiz Inacio Lula da Silva. Market participants are primarily concerned about potential increases in public spending, regulatory intervention in state-controlled corporations, and shifts in privatization policies. Foreign capital flows into Brazilian assets paused as portfolio managers reassessed country risk premiums. Analysts suggest that market volatility will persist until the new administration appoints key economic cabinet members and clarifies its legislative priorities.
