JSE closes slightly red; rates up, spirits down

The scoreboard

Thursday brought exactly the kind of mild disappointment we've come to expect from May. The Top 40 slipped 0.30%, which is the market equivalent of a sigh. Nothing dramatic. Nothing catastrophic. Just a quiet "ja, we're also not thrilled" from the JSE. Some decent movers kept things from getting truly grim, but the broader mood was constrained by the day's headline: the Reserve Bank hiking interest rates by 25 basis points. Investors are now doing that mental math on mortgage payments, and the market reflected their collective pause.

Winners of the day

Losers of the day

Why it happened

The Reserve Bank's 25 basis point rate hike was the elephant in the room. It signals that inflation is still a problem worth taking seriously, which is both good news (the SARB is doing its job) and bad news (your bond payments just got worse). Retail, healthcare, and leisure stocks tumbled because higher rates make consumers think twice before spending, and they tighten their purse strings. Meanwhile, financials like Finbond benefited from the wider net interest margin; higher rates mean better returns on deposits and fixed income products.

Eskom's continued demand to run coal plants longer than planned added another layer of uncertainty about South Africa's energy future. The market knows full well that load shedding and coal dependency are long-term drags on growth. Pick n Pay bucked the trend with a rare moment of optimism from a top investor, a small sliver of hope in an otherwise cautious day.

What to watch tomorrow

• How the banks trade off the rate hike. Higher rates are good for their margins, but bad for bad debts.
• Rand direction. A higher interest rate differential usually attracts offshore money; keep an eye on currency strength.
• Corporate earnings season. Expect companies to start guiding lower as they price in consumer weakness.
• Energy news. Eskom's coal gambit and load shedding updates remain market-moving.
