First-come, first-served application

Program call application
A SIB loan application for a non-TxDOT project or SIB loan over $10 million will be prioritized against other applications in a Program Call, if funds in the program are limited. Two Commission approvals may be required:
- Prioritization and preliminary approval of complete applications

For a list of prioritization considerations, please see §6.32(c)(1) of the SIB Rules.

Interest rate information
General information
The SIB uses the Municipal Market Index (MMD) to set interest rates. This index is updated weekly.
- Rates are set at the time we receive a completed application.
- The rate will be reset if the loan does not go before the Texas Transportation Commission within 12 months.
- Rate is determined based on the current credit rating of the borrower and the term of the loan
- The SIB team will use the AAA MMD scale for the term requested for the week of the application.
- A small premium will be applied based on the credit rating and requested term of the loan
- Credit rating not required to borrow.
- Fixed rate for the life of the loan.
