Sheikh Hasina has threatened the private banks with tough actions if they do not lower the rates of interest they charge to lend to or below 9 percent.
The move aims to alleviate traffic congestion and develop the public sector transport system, according to Finance Minister AHM Mustafa Kamal.
The duty, however, will not apply to passenger buses, trucks, lorries, three-wheelers, ambulances and school buses.
Kamal also plans to raise the supplementary duty on luxury transport services such as chartered aircraft and helicopters to 25 percent from the existing 20 percent.
