If you are shopping an SBA 7(a) or conventional commercial loan in Louisiana, the bank you call first matters more than most borrowers think. A lender that already writes a lot of commercial credit and sits in your state is structurally likelier to say yes than a national name passing through. This page ranks the Louisiana-headquartered banks doing the most commercial lending right now, using public Q1 2026 FFIEC call-report data. It is the open-book version of what the paid report does with far more inputs.
Louisiana's commercial banks underwrite around energy, ports, and weather, a risk mix that makes its lenders more cautious than outsiders expect.

C&I lending muscle, ranked
Commercial and industrial loans outstanding for the top 10 Louisiana-HQ lenders, Q1 2026. This is the single number our ranking leans on hardest.
How we ranked these
Three steps, all of them transparent. First, we took every bank headquartered in Louisiana. Second, we kept only banks whose commercial and industrial (C&I) loans are at least 10 percent of the loan book (a bank that is 90 percent home mortgages is not your SBA lender, regardless of size). Of the qualifying banks, 52 cleared that bar. Third, we ranked them by C&I loan dollars outstanding, which already blends balance-sheet size with how committed a bank is to commercial credit, and kept the top 15.
This is an honest, simplified proxy. It does not see a bank's actual SBA 7(a) origination volume (that lives in SBA FOIA data, not the call report), its appetite for your industry, or whether it funded forty SBA loans last quarter or zero. The $49 Borrower Assist report folds all of that in and ranks against your specific deal, not just your state. That is the part worth paying for.
What Louisiana looks like for a borrower
Louisiana's commercial banks underwrite around energy, ports, and weather, a risk mix that makes its lenders more cautious than outsiders expect.
Across 106 Louisiana-headquartered banks sits $82.9B in total assets, anchored by Origin Bank in Choudrant at $10.1B. Half the state's lenders hold more than 9.8% of their loans in C&I, half less; the ranking below pulls the most commercial-heavy to the top.
None of that tells you which of these banks will fund your specific deal. A $400,000 restaurant acquisition and a $4M owner-occupied warehouse purchase have different optimal lender lists even in the same state, and the ranking above does not split by loan size, industry, or collateral. Treat it as your starting shortlist, not your final answer.
How to use this list
- Start with the bank near you that has the strongest commercial profile, not just the closest branch. A lender with a real C&I book understands your deal faster.
- Ask for the SBA or commercial lending group directly. The general line routes business deals slowly.
- Have a one-page summary ready: use of funds, cash flow, collateral, owner credit, timeline. Banks decide whether to engage in the first ninety seconds.
- Run two banks in parallel, not five. Two real conversations close a loan; five waste everyone's time.
