The South Carolina Transportation Infrastructure Bank’s revenue bonds were upgraded to Aa2 from Aa3 by Moody’s Rankings, following a change within the rating agency’s methodology.

It was one among 225 credits Moody’s placed on review for possible upgrade July 25 when it released a revised rating methodology for “certain debt instruments supported by a pledge of special tax revenues that can now be rated under the sector methodology of the related government.”

Moody’s cited for Thursday’s upgrade its expectation that the state of South Carolina will proceed to support the bank. Moody’s rates South Carolina Aaa. The outlook is stable at the brand new rating.

The motion affects almost $1 billion in outstanding debt. It also affects a Series 2024A $151.9 million revenue refunding bond expected to sell on Sept. 9

“The upgrade to Aa2 relies on our expectation of strong support and oversight of the South Carolina Transportation Bank’s by its parent government, the State of South Carolina,” Moody’s said in its rankings report. “The state relies on SCTIB to finance large-scale transportation projects and has a record of augmenting the SCTIB’s revenue to make sure adequate debt service coverage and to supply adequate funding for capital projects.”

The bank’s revenue bonds are secured by a junior lien on truck and motorized vehicle registration fees, payments from the state’s Department of Transportation from non-tax sources like Federal Highway Administration funds, loan payments from local governments and the state DOT, transfers from a revenue stabilization fund, and investment earnings.

The bank funds large transportation projects through grants or loans.
