The document discusses two loan guarantees between USAID and EcoBank in Ghana from 2003-2008 and 2005-2012. It finds that the guarantees helped EcoBank expand lending to new sectors and provide longer term loans, but that EcoBank's overall lending growth was driven more by its retail banking strategy than the guarantees. The guarantees had a modest demonstration effect on broader banking sector lending but did not significantly impact total SME lending growth in Ghana.
