South African rand slips on Iran uncertainty ahead of key central bank data

The rand slipped on Iran uncertainty as Brent rose about 2% after US Secretary of State Rubio said a deal could take a few days. US forces had conducted defensive strikes in southern Iran.

South Africa's leading business cycle indicator for March was also due.

WHY IT MATTERS

Renewed Strait of Hormuz uncertainty lifts crude and risk-off demand for the dollar, which weighs on emerging-market currencies. Higher energy costs feed into fertilizer and feed input prices.
