The South African rand traded little changed against the dollar on Wednesday as investors awaited key inflation data expected to show the impact of rising global fuel prices linked to conflict in the Middle East.
At 0619 GMT, the rand traded at 16.68 to the dollar, close to its previous closing level, as markets adopted a cautious tone before the release of April consumer inflation figures.
Statistics South Africa was scheduled to publish the inflation data at around 0800 GMT, with economists polled by Reuters expecting annual inflation to accelerate to 3.9 percent from 3.1 percent in March.
Some analysts forecast an even sharper increase.
Economists at projected inflation could rise to 4.4 percent, driven mainly by higher transport and fuel costs following a surge in global oil prices.
South Africa imports most of its fuel needs, making the economy particularly vulnerable to fluctuations in international energy markets and geopolitical instability.

Oil prices have risen in recent weeks amid growing tensions involving the United States, Israel and Iran, raising concerns over inflationary pressures in fuel-importing economies.
The anticipated rise in inflation is likely to reinforce expectations that the South African Reserve Bank could adopt a more hawkish tone at its next monetary policy meeting on May 28.
The central bank has kept interest rates unchanged at its previous two meetings after earlier signs that inflationary pressures were easing.
However, analysts say a sharp rise in consumer prices could complicate any plans for future rate cuts.
Investors were also awaiting the release of March retail sales figures later on Wednesday, which economists said would provide further insight into the health of consumer spending in Africa’s most industrialised economy.
Retail sales are expected to show continued resilience before the full effects of the Middle East conflict filtered through to consumers and businesses.
Analysts forecast retail sales growth of 2.5 percent year-on-year in March, compared with 1.6 percent growth recorded in February.

Economists at said consumer spending earlier in the year had been supported by lower inflation, improved confidence and relatively favourable financial conditions.
“Household spending at that time would have been supported by the favourable inflation backdrop, easier financial conditions and improving sentiment prior to the full effect of the onset of the Iran war,” the bank’s economists said in a note.
Beyond domestic data, global investors continued to monitor geopolitical developments in the Middle East as well as diplomatic engagements involving Russia and China.
The U.S. dollar was broadly flat against a basket of major currencies in cautious trade, while financial markets remained sensitive to any signs of further escalation in global conflicts.
Emerging market currencies, including the rand, often come under pressure during periods of geopolitical uncertainty as investors shift towards perceived safe-haven assets such as the dollar.
Despite the uncertain global environment, South Africa’s government bond market showed modest strength in early trading.
The yield on the benchmark 2035 government bond fell 1.5 basis points to 8.915 percent, indicating slightly stronger demand for local debt.

South Africa’s economy continues to face multiple challenges, including weak growth, persistent unemployment, infrastructure constraints and pressure on household finances.
At the same time, policymakers are trying to balance inflation risks with the need to support economic activity.
Market participants are expected to closely analyse Wednesday’s inflation data for clues on the likely direction of interest rates and the broader outlook for the rand in the coming months.
A sharper-than-expected rise in inflation could increase pressure on the currency and reduce expectations for monetary easing later this year.
