Rand Investors Flee as Currency Heads Into Uncertain Month Ahead

SOUTH AFRICA’S CURRENCY FACES SEASONAL AND POLICY HEADWINDS IN AUGUST

Foreign investors pulled R6.2 billion ($376 million) out of South African bonds in July alone, a sharp reversal from R9 billion in inflows the month before. That swing captures the anxiety now surrounding the rand as it enters August carrying two compounding burdens: a well-documented seasonal pattern of weakness and fresh doubt about whether the South African Reserve Bank will defend the currency through interest-rate increases.

The seasonal drag is consistent. Since Bloomberg began tracking the data in 1997, the rand has lost more than 2% against the dollar in August on average. This year looks set to follow that pattern. As European summer holidays approach, traders reduce risk exposure and unwind carry positions, and the rand tends to bear the brunt. Hironori Sannami, a foreign-exchange trader at Mizuho Bank in London, put it plainly: “The rand, being one of the market’s favourite carry currencies, often finds itself on the receiving end of that seasonal position-squaring.” Carry trades profit from interest-rate differentials, making the rand attractive to yield-seeking investors, but that same appeal leaves it exposed when traders square up before vacations.

The deeper wound is policy-related. Last week, the Reserve Bank surprised markets by holding its policy rate unchanged while warning about upside inflation risks. The rand fell more than 2% against the dollar immediately after the decision and has not fully recovered. Gina Schoeman, Citigroup’s economist for South Africa, said the market is now questioning whether the central bank’s approach has fundamentally changed. “The market is looking for clarity as to whether the South African Reserve Bank’s reaction function has changed given how much inflation risk is on the line,” she said. Citigroup closed its bullish position on the rand versus the euro in direct response.

Meanwhile, pressure is building from abroad. The Federal Reserve’s hawkish stance this week threatens to erode the yield advantage that has long supported the rand. Mike Keenan, a fixed-income strategist at Absa Group, warned that if the Fed raises rates while the Reserve Bank holds steady, that advantage shrinks. Absa’s interest-rate model puts fair value for the rand at around R16.97 per dollar, nearly 3% weaker than its level near R16.50. “The ongoing correction in global equity markets and the growing prospect of Fed rate hikes are likely to keep the rand on the back foot over the coming months,” Keenan said.

Portfolio managers are already adjusting. Ruen Naidu, a portfolio manager at Ninety One, said the central bank’s reaction function appears to have shifted. “While it’s too early to say that the central bank’s stance has shifted, the early read is that the Sarb’s reaction function has shifted from ‘much higher’ to ‘moderately higher for longer,’” he said. That perception, confirmed or not, has already altered trading behavior and bond flows.

The anxiety is visible in the government yield curve, which has steepened as traders sell long-end bonds more aggressively, pricing in persistent inflation concerns and doubt about the Reserve Bank’s commitment to further rate increases. For currency traders and bond investors alike, August arrives as a month when seasonal weakness and policy uncertainty reinforce each other. Whether the Reserve Bank’s next move resolves that doubt or deepens it will determine how much further the rand has to fall.
