South Africa’s current-account unexpectedly swung to a deficit in the second quarter as imports outweighed exports and companies paid higher dividends. The balance on the current account, the broadest measure of trade in goods and services, switched to an annualized deficit of 1.3% of gross domestic product, or R87-billion, from a revised 2.4% surplus in the previous quarter, the South African Reserve Bank said in a report on Thursday. Only one of 11 economists in a Bloomberg survey forecast a deficit to GDP.
