Brazil's real rose 0.6% on Friday after consumer inflation for the month to mid-July hit its highest in 17 years, boosting expectations of a 100 basis point rate hike at the August central bank meeting. Russia's central bank also raised rates by 100 basis points that day, its steepest hike since 2014.
Colombia's peso was the weakest Latin American currency for the week.
Higher Brazilian interest rates support the real, which tends to make Brazilian exports such as soybeans, corn and meal relatively more expensive for foreign buyers and can weigh on dollar-priced grain values. The broader trend of EM rate hikes is a macro signal rather than a direct grain supply factor.
After 213 past bearish macro events, Brazilian Real (BRL per USD) moved a median -0.2% over 5 sessions (46% higher; middle half -1.5% to +0.9%), and +0.2% over 20.
