Brazil Central Bank Conducts Dollar Auction to Inject Market Liquidity

The Central Bank of Brazil conducted two simultaneous operations on Thursday to inject liquidity into the foreign exchange market. The bank sold 1 billion US dollars in spot currency while simultaneously auctioning 20,000 reverse currency swap contracts valued at 1 billion US dollars. This combined operation, known as a casadão, has a neutral effect on the exchange rate because the bank bought and sold the same amount.

Market analysts suggest the move was prompted by heavy financial outflows. Data from the Central Bank shows a negative balance of 2.55 billion US dollars from the start of August until August 21, with a net exit of 4.055 billion US dollars in the final week of that period. Leonel de Oliveira Mattos, an analyst at StoneX, stated that the bank intervenes when there are asymmetries in supply and demand to prevent market dysfunction. He added that the bank may be reducing its swap stock to maintain the efficiency of future interventions.

Foreign investment in the Brazilian stock market has declined, with B3 reporting a negative balance of 20 billion Brazilian reais for foreign investors in August. This follows a strong start to the year when 26.5 billion Brazilian reais entered the market in January. Factors contributing to the current exit include a revised Selic rate projection of 13.75 percent and global instability. Specifically, the war in Iran has led global investors to reduce allocations in emerging markets in favor of more liquid assets. The DXY index, which tracks the US dollar against a basket of strong currencies, has risen 1.55 percent since late February.
