Nigerian President Muhammadu Buhari is due to address the nation on Thursday morning amid a shortage of the newly designed banknotes that has led to a lack of cash.
The presidency says Mr Buhari’s address will start at 07:00 local time (06:00GMT), but gives no hint on what he will talk about.
Africa’s biggest economy has witnessed angry protests in towns and cities as people struggle to get hold of the new banknotes.
Some customers in southern Nigeria’s Warri and Benin City reportedly set fire to two commercial banks.
Nigerians have faced long queues at cash machines with some sleeping outside banks to try and be the first in line to get some money.
