South Africa faces the highest rate in sub-Saharan Africa, reflecting Trump's strained relationship with the government of President Cyril Ramaphosa. Other African nations, including Nigeria, Ghana, Lesotho and Zimbabwe have been hit with a 15% tariff, which will also come into effect in seven days.

The South African rand was on the backfoot in early trade on Friday, as investors weighed the prospect of higher tariffs on exports to the United States after the country failed to clinch a trade agreement before Washington's deadline.

South Africa, which has a strained relationship with President Trump, is the only African country singled out in the announcement with a 30% tariff increase on August 7.
