U.S. President Donald Trump's tariffs on South Africa could cause around 100,000 job losses, with the agriculture and automotive sectors hardest-hit, central bank governor Lesetja Kganyago said on Wednesday.

Chipmaking equipment supplier ASML said the impact of US tariffs was “a bit less negative than we anticipated”, as artificial intelligence drove strong orders for its lithography machines.

Egg prices cooled significantly in June, deviating from an overall rise in prices. The price of eggs climbed 27% over the year ending in June, which marked a slowdown from 41% year-over-year growth in May.

Approval for Brazilian President Luiz Inacio Lula da Silva's government rose for the first time this year, a new poll showed on Wednesday, after his U.S. counterpart Donald Trump announced a 50% tariff on imports from Brazil starting in August.

Four months since Trump fired the opening salvo of his trade war, only China and Canada have dared to hit back at Washington imposing a minimum 10 per cent global tariff, 50 per cent levies on steel and aluminium, and 25 per cent on autos.

President Donald Trump in recent days slapped tariffs as high as 50% on dozens of countries, restoring the type of aggressive trade policy that sent stocks plummeting a few months ago. The new round of levies prompted little more than a shrug on Wall Street.

European Union officials have drawn up plans to impose levies on American imports, but questions abound about whether they would go through with them.

President Donald Trump told reporters Tuesday that he plans to place tariffs of over 10% on smaller countries, including nations in Africa and the Caribbean.
