WASHINGTON — The Inter-American Development Bank (“IDB” or “IADB”), rated Aaa/AAA (Moody’s/S&P), priced a new $3 billion 10-year USD Global Sustainable Development Bond (SDB) Benchmark.
The transaction pays a semi-annual coupon of 4.375% and matures on July 16, 2035. It was priced with a spread of 61 basis points over SOFR mid-swaps, equivalent to 6.93 basis points over 4.25% United States Treasury due May 2035. Final order books exceeded $8.3 billion, including $550 million in Joint Lead Managers' interest.

“We are thrilled with the success of our $3 billion 10-year USD Sustainable Development Bond. It is our largest 10-year IDB orderbook with over $8.3 billion demand which allowed us to print a larger than expected transaction,” said Laura Fan, Head of Funding at the IDB. “The record-tight spread of 6.93 basis points over the 10-year US Treasury reflects robust investor confidence in the IDB’s credit and our mission to promote economic and social development across Latin America and the Caribbean."
