EMERGING MARKETS-South African rand rises with eyes on cbank rate decision, other FX slide

* South African central bank expected to hold rates steady

* MSCI emerging market currency index slips to two-week low

* Developing world stocks hit lowest level so far in 2021

* Turkey’s weekly forex reserves data due later in the day

March 25 (Reuters) - The South African rand firmed on Thursday ahead of a central bank policy decision on interest rates, while other emerging market currencies and stocks slipped for a fifth straight day on fears of a potential global tightening in monetary policy.

The rand was up about 0.2% against the dollar, rising for the first time in four days as the spillover from a central bank shake-up in Turkey faded.

South Africa’s Reserve Bank (SARB) is expected to keep its repo rate at a record low of 3.5%, particularly as data on Wednesday showed the domestic consumer inflation rate dipped below its target range in February.

“We assume that the rate vote will confirm the SARB’s foresighted and stability-orientated course, so we do not expect significant momentum for the rand on this front,” Elisabeth Andreae, FX analyst at Commerzbank, wrote in a note.

A basket of emerging market stocks slid to its lowest level this year, with Chinese and Hong Kong equities slipping as the U.S. securities regulator moved to impose measures that could de-list some Chinese firms from U.S. exchanges.

The MSCI index of developing world currencies fell about 0.2% to a two-week low as expectations of stronger U.S. economic growth, rising U.S. bond yields and new COVID-19 lockdowns in Europe lifted the dollar.

“A stronger dollar will dampen demand for emerging markets commodities and make their dollar-denominated debt challenging to service, especially with rising longer-term interest rates,” said Hussein Sayed, chief market strategist at FXTM.

“So far, this risk seems insignificant but another sharp spike in yields and the dollar will increase the probability of a sovereign debt crisis in the EM world.”

The Turkish lira eased about 0.6% after slumping 7.5% on Monday after President Tayyip Erdogan replaced a hawkish central bank governor with a critic of high interest rates, sparking fears of a reversal of rate hikes that had revived the currency amid Turkey’s depleted forex reserves.

The central bank is due to release its weekly data on forex reserves at 1130 GMT, although the figures cover the week ended March 20, before the market turmoil from the latest central bank shake-up.

The Russian rouble rebounded 0.8%, supported by local tax payment requirements, after hitting its lowest so far this year on Wednesday on fears of new U.S. sanctions.

Later in the day, eyes will be on Mexico's central bank policy meeting, with signs of quickening inflation raising expectations that the bank will hold interest rates. The Mexican peso was up about 0.1% against the dollar on Thursday.
