The JSE retreated on Monday primarily on the back of losses recorded on the resources index.
The firmer rand played an important role as it extended its gains against the greenback.
This saw rand-denominated prices of metal commodity prices fall which resulted in weakness for most of the locally listed miners.
The JSE also shrugged off earlier momentum from Chinese markets which rallied on the optimism of a partial trade deal.
The rand held on to its gains as it peaked at a session high of R14.72/$ before it was recorded trading 0.01% firmer at R14.79/$ at 17:00.
