Lula's surprise re-election triggered a sharp drop in the Brazilian real that spread to Argentina, causing large intraday moves in local markets. Argentina's official retail dollar held near ARS 1,560 while the wholesale rate fell to about ARS 1,538.
Central bank reserves rose modestly to about USD 50.58 billion, with the Treasury reportedly selling about USD 100 million to contain the peso.
Argentine currency stress affects feed and oilseed buyers through import costs and financing capacity, and a weaker real typically pressures Brazilian soybean and meal export prices in dollar terms.
After 213 past bearish macro events, Brazilian Real (BRL per USD) moved a median -0.2% over 5 sessions (46% higher; middle half -1.5% to +0.9%), and +0.2% over 20.
