Analysts on Wednesday said Africa's biggest economy, heavily dependent on the wider global economy's health, will be hurt by the uncertainty stemming from sovereign debt worries in the U.S. and Europe.

Bank officials told members of parliament consumer spending was expected to underpin growth in the economy even as external uncertainties remain, but recent data shows indebted households are still reluctant to spend after a recession in 2009 which slashed a million jobs. The Treasury expects growth of 3.4 percent this year as the economy slowly recovers, helped by 650 basis points of interest rates cuts in the two-years to November last year -- but some analysts see a lower outcome as global growth s. -- SPA
