The Central Bank of Brazil announced simultaneous auctions on June 25, 2025, selling $1 billion in spot dollars and an equal amount in reverse FX swaps. Traders debated whether this tool would be used more often, with the swap stock at $101 billion and reserves at $341 billion.
Central bank dollar sales can ease spot-market demand and cap real weakness, which lowers the local cost of dollar-priced feed imports and affects Brazilian export competitiveness.
After 13 past bearish policy events, Brazilian Real (BRL per USD) moved a median -3.4% over 5 sessions (15% higher; middle half -3.4% to -1.3%), and -1.9% over 20.
