The financial system of Ghana (thanks for your help)

The financial system of Ghana includes business intermediaries such as the central bank owned by the government. As well as commercial banks, specialized banks, foreign-owned financial institutions and other financial institutions. There are four big banks in this country, including Ghana's Commercial Bank, Barclays Bank Ghana, Agricultural Development Bank and Ecobank Ghana Limited. In 2008, The Ghanaian central bank declared that the reserve ratio should improve, which triggered a large scale of merging and acquisitions. For example, The Bank of Africa merged with Ghana’s Amalbank, Access Bank merged with Intercontinental Bank and Ecobank merged with The Trust Bank.
In Ghana, economic dealers such as householders, businesses institutions, governments, analysts and observers argue that the banking system is not competitive. Currently the financial sector of Ghana is made up of 23 banking institutions, 126 rural banks and 41 NBFIs (Bank of Ghana Annual Report 2007). Of the 23 banking institutions, 22 banks providing universal banking businesses are limited to enter into only domestic banking businesses, while a foreign-owned bank aiming at general banking services is allowed to enter into all forms including domestic and international banking which involves both residents and non-residentential clients.
