Fare hike follows doubling of metro ticket price in 2017.
Commuters now pay a base fare of EGP 3 for the first nine stops and an additional EGP 2 (total EGP 5) for seven more stations. The highest ticket price of EGP 7 applies to more than 16 stops.
The fare increase is the second in just over a year and replaces the old system whose EGP 2 ticket price was not determined by the number of stations.
The announcement of the new ticket fares, which follows negotiations between Egypt's transport ministry and the loss-making Cairo Metro Company, coincides with the completion of new ticket gates at the city's metro stations.
The ministry said the increase was necessary to fund the development of the metro infrastructure in the greater Cairo area as well as cover operating costs, and pointed out that there are discounted fares for government workers, students, senior citizens and people with disabilities.
