JOHANNESBURG, March 30 (Reuters) - South Africa's rand
firmed against the dollar on Thursday after the central bank
raised its main interest rate by a higher than forecast 50 basis
points to 7.75%.
At 1521 GMT, the rand , which flirted with an almost
2 percentage point jump right after the surprise decision, was
trading at 17.8600 against the dollar, up 1.45% from its
previous close.
It breached the 18 rand per dollar barrier for the first
time in over six weeks.
A majority of economists polled by Reuters had expected the
South African Reserve Bank to announce a 25 basis point
increase, but central bank governor Lesetja Kganyago said
inflation expectation was still on the upside.
"Despite some easing of producer price and food inflation,
global price levels remain elevated," he told a media
conference.
Statistics South Africa data showed last week that February
inflation rose to 7.0% year on year from 6.9% in January,
remaining above the bank's target of between 3% and 6%.
With interest rates now well above the rate of inflation, it
means investors are earning a higher rate on their investment
than the rate at which prices are going up, generally considered
a positive trend.
But analysts were not convinced that the local currency
would reflect that sentiment for long.
"The rand is a short-term beneficiary of the surprise
decision to hike rates more than was anticipated," said Shaun
Murison, senior market analyst at IG.
The longer trend of the so-called riskier currency is
towards weakening, he added.
Shares on the local bourse continued their upward trajectory
for the fourth consecutive day with the blue-chip Top 40 index closing 0.32% higher at 71,089 points while the
benchmark all-share index ended up by 0.29% at 76.705
points.
The blue-chip index has gained almost 3.5% in market value
this week, primarily driven by an improvement in bank and mining stocks.
The government's benchmark 2030 bond was
stronger, with the yield down 8.5 basis points to 9.900%.
