South Africa said it will submit a revised offer for a US trade deal in an attempt to lower the 30% tariff rate imposed on exports from Africa’s biggest economy. The duty, which came into effect on Aug. 7, is the highest tariff imposed on a sub-Saharan African country.

JPMorgan said on Tuesday the recently imposed 30% U.S. tariffs on South African exports are expected to have a limited effect on the country's assets, as markets have "largely priced in the reality of higher tariff headwinds".
