Less than 5 percent of Cameroonians have access to a bank account. While the microfinance sector is consequently becoming increasingly important, its development is hampered by a loose regulatory and supervisory framework for microfinance institutions (MFIs). The banking sector is highly concentrated and dominated by foreign commercial banks. 6 out of the 11 largest commercial banks are foreign-owned, and the three largest banks hold more than 50 percent of total financial system assets. While foreign banks generally display good solvency ratios, small domestic banks are in a much weaker position. Their capitalization is well below the average of banks in the CEMAC region and their profits are close to 2 percent, compared to 20 percent for foreign banks in the country. This is partially explained by the high levels of non-performing loans, which reached 12 percent in 2007, leading to most banks holding large amounts of excess reserves as a percentage of deposits and large levels of unutilized liquidity.
