Rand on back foot, may weaken if current account gap widens
The local unit fell to a session low of 10.8640 per dollar, the weakest it has been since March 24, and was trading at 10.8340 by 0645 GMT, not far off Tuesday's New York close.
Economists polled by Reuters expect the Reserve Bank's quarterly bulletin due out at 0800 to show the current account deficit widened to 6.1 percent of GDP in the first quarter from 5.1 percent.
Consumer inflation and retail sales data to be released at 0800 GMT and 1100 GMT respectively are also likely to show the economy remains in a dire state.
"We heard nothing that should inspire the rand, despite its correct focus on the economy," Cairns said.
Government bonds weakened, with yields for the benchmark 2026 and 2015 paper adding 4 basis points to 8.48 percent and 3.5 basis points to 6.76 percent respectively.
