Fitch downgraded Mexico's credit rating to BBB- with a stable outlook on April 16, 2020. The Mexican peso weakened, with USD/MXN rising from 23.95 to around 24.23 amid broad risk aversion linked to COVID-19 deaths and weak US data.
A weaker peso raises the cost of dollar-denominated feed imports for Mexican buyers, while the risk-off move supports the dollar and pressures commodity prices broadly.
