CAPE TOWN, Oct 31 (Reuters) - South Africa's government was bracing for an unfavourable review of the country's final investment grade credit rating on Friday, bringing an exodus of foreign money from an already debt-riddled economy a step closer.
Moody's pegs South Africa at Baa3, its lowest investment grade rating, with a "stable" outlook.
The credit agency - the last of the big three agencies not to have consigned South Africa's rating to 'junk' status - told the treasury it was looking "very carefully" at the country's fiscal position before publishing its review, said Finance Minister Tito Mboweni.
"At the most I hope they keep the rating where it is. ... It's not looking good," he told parliament.
On Wednesday, Mboweni forecast wider budget deficits and soaring debt. The economy is barely growing, and also saddled with chronically high unemployment.
While many analysts believe an immediate downgrade remains unlikely despite that bleak mid-term budget outlook, they said Moody's looked almost certain to deliver some sort of negative assessment.
It could put South Africa on "outlook negative", which would provide a window of 12-18 months before a downgrade might be delivered. Alternatively, a move to "credit watch negative" could lead to a ratings decision within three to six months, they said.
"Moody's has to go to negative now if they want to have a shred of credibility," said Kevin Daly at Aberdeen Standard Investments in London.
Markets have reacted nervously to the glum projections, with the rand weakening more than 1% after a 2.5% drop on Wednesday, its largest daily decline in over a year.
A full downgrade to non-investment grade would see South Africa evicted from the benchmark World Government Bond Index (WGBI) of local currency debt and trigger a sell-off by investors mandated to buy high-grade debt.
Goldman Sachs said in August that a downgrade of the local issuer rating could lead to $5 billion in passive outflows and up to $10 billion in active outflows.
With funds tracking the WGBI having $172 billion under management and South Africa’s weight of 0.44% in the index, the $5 billion outflow could happen in the space of two months, predicted Reezwana Sumad, senior research anlyst at Nedbank.
Goldman Sachs said on Thursday that, while there was now "a higher probability (from a low level) of an immediate downgrade," its main scenario remained a shift of the outlook to "negative", either on Friday or shortly thereafter.
JPMorgan also forecast a negative outlook, with a base case for a downgrade in the fourth quarter of 2020. (Reporting by Mfuneko Toyana and Karin Strohecker in London, Additional reporting by Tom Arnold; writing by Karin Strohecker and Alexander Winning; editing by John Stonestreet)
