"Somalia has made important reforms and has demonstrated strong commitment to staying the course," said Hafez Ghanem, World Bank vice president for Africa.
"These reforms lay the foundation for sustained poverty reduction and better lives for the Somali people, and open the door to private sector investment that can create jobs and drive the economy forward," he said in a statement.
This month the African nation has won initial approval from World Bank and IMF to get hundreds of millions in debt relief.
New financing proposals that should be ready in the coming months aim to provide rapid response to households impacted by recent droughts and flooding.
The proposals also aim to reduce poverty by delivering social protection to over 200,000 women with children under 5, it said.
Somalia Finance Minister Abdirahman Beileh said the approval "is a recognition of the ambitious reforms to which this government remains committed, to bring transparency and accountability into Somali institutions and to revive the economy."
Almost 70 percent of Somalis live on less than $1.90 a day.
