The grand standing has caused anxiety especially among businesspersons who fear that their premises would be broken into.
While a section of electronic shops in downtown were not opened as usual, some have opened, but staff watching from outside.
Some supermarkets within the centre were open for early morning customers among them those along Ronald Ngala Street.
In uptown, the cops were seen patrolling in two's armed with teargas on their waists and clubs in hands ready for the day.
On city routes, some matatus were spotted parked on petrol stations while a few operating as usual.
In Eastlands, city residents who rely on Commuter trains were notified that normal services would not be available.
Around Wakulima and Muthurwa markets, activities were usual as traders offloaded goods from parked tracks.
Wakulima market Chairman Cyrus Kaguta said traders usually protect their wares whenever there are such demonstrations.
"Traders around Wakulima and Muthurwa markets usually protect their goods from opprtunists unless in few areas along Haile Selassie," Kaguta said.
Raila said the Monday and Thursday will continue until President William Ruto's regime lowers the cost of living.
"We will not have a country if we do not fight against bad governance. We are not looking to cause anarchy in the country; we are fighting for our rights and we have the right to tell Kenyans the truth," Raila said.
