The Nigerian government has criticized the heightened response of what it considers administrative decisions to move the department of banking supervision of the Central Bank of Nigeria (CBN) and the head office of the Federal Airports Authority (FAAN) to Lagos. The federal government says these measures are not tantamount to the relocation of the administrative capital of Nigeria back to Lagos but to ease the supervisory and regulatory roles of these government agencies. Over 90% of banks in Nigeria have their headquarters in Nigeria and the movement of the department directly in charge of their supervision is expected to provide a greater platform for effective banking supervision. Also, Lagos airports account for about 75% of air movements and the proximity of FAAN will also improve work and effectiveness of the agency.
