JOHANNESBURG: South Africa's rand was on course for a loss of more than three percent against the dollar this week, as five consecutive days of power cuts reminded investors about the fragility of an economic recovery.

Struggling state power firm Eskom implemented one of the worst power cuts in several years from Sunday to Thursday, hurting small businesses without backup power generators and industrial firms that consume large volumes of power.
Eskom said power cuts were not likely on Friday, but warned the power system remained vulnerable.
Investors are waiting for more details on how President Cyril Ramaphosa's government plans to shore up Eskom's balance sheet - plans which should be unveiled during a budget speech by the finance minister on Feb. 20.
After this week's steep fall in the rand, Nedbank CIB analysts said they were more comfortable that risks to the currency were better priced.
"South Africa's fiscal position has come to the fore as the market anxiously awaits more details on Eskom and how the government will account for this in the budget," Nedbank CIB analysts wrote in a research report.
