Afghanistan and Tunisia are looking into issuing a sovereign Bitcoin bond, Asia Times writes. The countries’ central bank governors believe state crypto bonds could help them with obtaining investments. They both spoke at the annual Spring Meetings of the Boards of Governors of the World Bank Group and the International Monetary Fund in Washington last week.

Governor at the Central Bank of Afghanistan Khalil Sediq said a crypto bond could help the country raise some of the US$5.8 billion that Afghanistan needs for its mining, energy and agriculture industries. Since the country is subject to restrictions on non-concessionary borrowing, issuing bonds and metal futures could be a way to access international markets. The country is hoping to leverage its vast lithium reserves, whose value is estimated at over $3 trillion. It is also aiming to become a significant player in the lithium mining business.

Tunisia, on the other hand, has created working groups that are investigating the issuance of a sovereign Bitcoin bond. The country already has its own digital currency—the e-dinar—and accepts digital payments through a Poste Tunisienne.
