SBA loan basics
Short answer
The SBA guarantee encourages banks by reducing their financial risk. If a small business borrower defaults, the SBA covers a significant portion of the loss, making lenders more willing to approve loans they might otherwise consider too risky.
Banks are inherently risk-averse. The SBA's guaranty acts as a credit enhancement, allowing lenders to extend credit to businesses that may have less collateral, a shorter operating history, or operate in a niche industry. This increased confidence from the guaranty enables banks to offer more flexible terms and reach a broader pool of small business borrowers.
A bank assesses a small business loan application as having a 20% chance of default. With an 85% SBA guarantee, the bank's actual exposure to loss if default occurs is significantly reduced, making the loan more attractive.
