The Nairobi Securities Exchange said it would extend trading to 5pm, from the usual 3pm, after it managed to resolve a technical hitch which stopped trading for most of the day.
The largest stock market in East Africa had earlier said a link to the central depository system, a back office which processes trades, had failed, leading to halting of all trading activities.
One market participant said trading had been unavailable for several hours during the day.
The bourse said the services were restored just before 4pm.
