The rand weakened on June 11 after the US Federal Reserve projected a 6.5% contraction in the US economy this year and 9.3% unemployment at year-end. The currency moved from a strongest-since-March level of R16.32 to R16.71 per dollar.
South Africa's central bank had projected a 7% contraction for the local economy.
A weaker rand raises the local-currency cost of imported feed ingredients, while a gloomier global outlook supports safe-haven demand for the dollar. The effect is macro rather than grain-specific.
