The South African rand moved higher on Thursday afternoon after the central bank raised its key interest rate and official data showed a marked pickup in producer price inflation for April.
At 1410 GMT the currency was trading at 16.32 against the U.S. dollar, reflecting a 0.3% gain from the previous session's close. Market participants treated the move as a response to tighter monetary policy combined with signals of accelerating price pressures in the domestic economy.
The South African Reserve Bank increased its policy rate by 25 basis points to 7%. This is the central bank's first rate rise in three years. The bank said the step was needed to steer inflation back toward its target following the sharp acceleration seen in April. This decision places South Africa among a small group of emerging markets that have tightened policy during the Iran war.
Recent inflation data showed consumer inflation running at 4% on an annual basis last month, above the Reserve Bank's 3% target. Separate figures released on Thursday indicated that producer inflation climbed substantially in April, rising to 4.8% year-on-year from 2.3% in March.
The combination of a policy rate increase and higher producer price inflation contributed to the rand's appreciation against the dollar in afternoon trading. The central bank framed the rate increase as necessary to return inflation to target levels after the April acceleration.
Observers noted the policy move is notable because it is the first hike in three years and comes amid a broader geopolitical backdrop referenced by the bank, with South Africa now among the limited number of emerging market central banks to tighten policy during the Iran war.
