The US dollar gained about 17% against the Brazilian real in the first half of 2018, closing June at BRL 3.8773. Most of the rise came from April to June, amid US-China trade war concerns and uncertainty ahead of Brazil's October presidential election.
The Brazilian Central Bank had injected about USD 43 billion through swap and repurchase auctions since May 14.
A weaker real makes Brazilian soybean, corn and meal exports cheaper and more competitive on world markets, which can support US export prices and the global feed cost base.
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.
