A nationwide strike in Argentina against austerity measures under President Macri shut airports and halted work at key grain ports on May 29, according to Reuters. Grain exports stopped at Rosario, the country's main agro-industrial hub.
The strike comes as Macri's popularity falls ahead of October presidential elections.
A halt at Rosario ports disrupts soybean meal and oil shipments, which can tighten nearby export supply and firm meal and oil prices briefly until flows resume.
