The Federal Reserve's H.10 weekly release lists foreign exchange rates for the period July 30 to August 3, 2018, in currency units per US dollar. It shows the Brazilian real at about 3.71 to 3.76 per dollar, the Chinese yuan at about 6.80 to 6.84, and the Mexican peso at about 18.5 to 18.6.
The euro was about 1.16 to 1.17 per dollar.
This is a routine data release with no new cause, so it gives no clear directional signal for feed prices. It mainly serves as a reference for currency-driven export competitiveness.
After 40 past report events, Brazilian Real (BRL per USD) moved a median -0.1% over 5 sessions (48% higher; middle half -1.3% to +1.3%), and -0.2% over 20.
