Riyadh, which since March 2015 has led a military coalition to support pro-Hadi fighters in Yemen, has made no official announcement on the aid.
Hadi said the oil-rich neighbouring kingdom had allocated USD 10 billion "for the reconstruction of liberated provinces, including USD 2 billion as a deposit in the central bank to shore up the (Yemeni) riyal", the Saba news agency reported.
The president, speaking in the government's temporary southern capital of Aden, called on his government to focus on power, water, roads, health and education in retaken areas.
More than 7,400 people have been killed since the coalition intervened in impoverished Yemen two years ago, including around 1,400 children, according to the United Nations.
