This study investigates the efficiency of the Nigerian banking system between the years of 1999 and 2005. Bank efficiency is evaluated using Data Envelopment Analysis (DEA), and the main determinants are identified by using a Tobit model. The results indicate that efficiency fluctuated during the first part of the period and improved during the recent years, a period associated with the increase in minimum capital requirement. Differences in bank efficiency are explained by problematic loans and bank size.
