CDFI Bond Guarantee Program Improvement Act of 2023

This bill amends the CDFI Bond Guarantee Program to improve how the government guarantees bonds issued by community development financial institutions (CDFIs). It sets a minimum guarantee of $25 million per transaction while capping total annual guarantees at $1 billion, and extends the program's deadline to four years after enactment. The bill also requires the Treasury Secretary to report to Congress on the program's effectiveness within one and three years of enactment. These changes aim to provide CDFIs with more predictable long-term capital to fund projects in underserved communities.
