The Brazilian real fell 9.15% after Lula da Silva won the presidential election, while the Argentine peso depreciated only about 1.5% over the same period. The central bank and Treasury intervened to contain the peso's movement.
Analysts expect this gap to be unsustainable, while the government disagrees.
A weaker real makes Brazilian soybeans, corn and meal cheaper for export buyers, which pressures world prices. Argentina's peso policy also affects the competitiveness of its soy and corn exports.
After 301 past bullish macro events, Brazilian Real (BRL per USD) moved a median +0.4% over 5 sessions (57% higher; middle half -1.2% to +1.7%), and +1.0% over 20.
