Brazil's balance of payments is structurally linked to global commodity cycles. Soybeans and iron ore alone represent over 25% of total merchandise exports. Commodity price swings directly drive current account surpluses/deficits and BRL exchange rate volatility.
High SELIC rates attract international carry traders borrowing in low-yield currencies (USD, EUR, JPY) and investing in Brazilian real-denominated assets. During risk-off periods this capital reverses instantly, causing sharp BRL depreciation.
Rather than selling hard dollar reserves, the BCB uses domestic FX swaps (settled in BRL) to sell dollars in the futures market. This protects reserves while providing exchange rate stability to domestic investors and corporations with USD liabilities.
Commodity trade surplus offset by services deficit (tourism, freight, royalties) and large primary income deficit (profit repatriation by foreign multinationals). Net FDI typically covers the gap but is sensitive to global risk appetite. See Brazil Financial Architecture.
