5 minutes. That is all it took for the market story to change.
In this episode of Number of the Day, Gareth Edwards and Francis Herd unpack one of the most dramatic trading reversals of the day: oil dropping sharply in just 300 seconds after a sudden change in market sentiment around possible US action against Iran. What began as a panic over the risk to energy infrastructure and the Strait of Hormuz quickly turned into a global relief move, and markets reacted instantly.
The conversation tracks the chain reaction clearly. Oil had surged above $112 a barrel, the rand weakened to around R17.20 to the dollar, and the JSE was deep in the red. Then came the signal that planned US action against Iranian energy infrastructure would be delayed for five days after what Donald Trump described as productive talks. Within minutes, oil tumbled, markets rebounded and the mood flipped.
For South Africans, that matters because oil shocks do not stay in trading terminals. They feed into the rand, fuel prices, inflation pressure and business confidence. The hosts also make the point that the story is not over. If the geopolitical situation changes again, the market could turn just as fast in the other direction.
5 minutes. 300 seconds.
A reminder that in a volatile world, one geopolitical signal can ripple straight into the South African economy. The transcript explicitly frames the number as “5 minutes or 300 seconds,” says the oil price fell from roughly $113 to $98 in five minutes, and notes the rand hit R17.20 before the reversal. Reuters also reported that oil fell more than 13% after Trump postponed planned strikes on Iranian energy infrastructure, while broader markets rebounded.
