The Seychelles Blue Bond was the first bond explicitly advertised as “blue”. It was launched in October 2018 by the Republic of the Seychelles for an amount of USD15 million with a maturity of 10 years and a coupon (annual interest payment) of 6.5%. In January 2019, the Nordic Investment Bank (NIB) issued a SEK 2 billion (USD 200 million) blue bond to protect and rehabilitate the Baltic Sea. Under the Seychelles bond, the proceeds from the transaction will be used to support the expansion of marine protected areas, improve governance of priority fisheries and the development of the Seychelles' blue economy. Through the Baltic Sea bond, the issuing bank will support lending to waste water treatment and water pollution prevention projects, storm water systems and flood protection, protection of water resources, protection and restoration of water and marine ecosystems and related biodiversity (wetlands, rivers, lakes, coastal areas and open sea zones). Both the Seychelles and the Baltic bond follow in their design green and other impact bonds, notably social and sustainability bonds. The difference between these and classic bonds is that they are issued on the promise to use the funds raised for specific green, climate and/or social purposes.
