The SBA Just Expanded Rate Options for 7(a) Loans. Here's What It Means for Your Acquisition.

Starting March 1, 2026, SBA lenders can price variable-rate 7(a) loans using three new base rate indexes: SOFR, the 5-year Treasury Note Rate, and the 10-year Treasury Note Rate. Until now, lenders were limited to two options - the Wall Street Journal Prime Rate and the SBA Optional Peg Rate.

This matters if you're financing a business acquisition. Not for the reasons you'd expect.

The rate gap is real#

SOFR currently sits around 3 percentage points below Prime. The 5-year and 10-year Treasury rates also track well below Prime, running in the low 4% range versus Prime at 6.75%. On paper, that's a meaningful starting-point difference for a variable-rate loan.

But the SBA's maximum allowable interest rate hasn't changed. Whether your lender uses SOFR, Treasury rates, or Prime as the base, the total rate (base plus spread) can't exceed Prime plus the standard spread for your loan size:

For most acquisition loans - typically north of $350K - the ceiling is still Prime + 3.0%. Unchanged.

So what changes in practice?

Different indexes, different behavior#

The value isn't in a lower maximum rate. It's in how these indexes move over time.

Prime tracks the federal funds rate almost perfectly. When the Fed cuts or raises, Prime adjusts within days. Blunt and immediate.

SOFR and Treasury rates respond to broader market dynamics. They can move independently of Fed actions, sometimes in opposite directions. For a buyer on a 10-year acquisition loan, having a base rate tied to the 10-year Treasury means your interest rate moves with the same forces that price long-term debt - not short-term Fed policy alone.

That difference matters most during economic uncertainty. If the Fed holds rates steady but long-term yields drop on recession expectations, a Treasury-indexed borrower benefits while a Prime-indexed borrower sees no change.

There's a stability angle too. The notice allows SOFR to be calculated using 30-day averages rather than the volatile daily rate, and Treasury rates update monthly rather than with every Fed meeting. Depending on the structure, payments could be more predictable than traditional Prime-based quarterly adjustments.

The secondary market restriction is the real story#

Here's where it gets practical.

Loans using these alternative base rates cannot be sold on the secondary market. At least not yet. The SBA says it will "evaluate the secondary market demand," but for now, this is a hard restriction.

This is a bigger deal than it sounds. Roughly 80% of SBA 7(a) lenders sell the guaranteed portion of their loans in the secondary market, often at premiums of 110-113%. That gain-on-sale model is the economic engine behind high-volume SBA lending. As Heather Endresen of Live Oak Bank has noted, if a bank pays costs on your loan, "it's going to be factored in to their pricing model, and passed on to you." Lenders who depend on secondary market sales have no incentive to offer base rates that make their loans unsellable.

The lenders most likely to offer SOFR or Treasury-indexed SBA loans are portfolio lenders - community banks and credit unions that hold loans on their balance sheets. These are the same lenders who tend to offer better rates and more flexible terms. SearchFunder community data shows portfolio-oriented lenders routinely close at Prime to Prime + 1.5%, well below the maximum. The alternative base rate option gives them another tool that aligns with how they already price commercial loans.

For buyers, this creates a useful signal. If your lender offers SOFR or Treasury-based pricing on an SBA loan, they're a portfolio lender. That often correlates with lower rates, better workout flexibility, and stronger post-close relationships.

How to Choose an SBA Lender for Your Acquisition

What to do if you're closing after March 1#

Add these to your lender conversations:

"Will you offer SOFR or Treasury-indexed rates on my SBA loan?" A yes identifies a portfolio lender willing to hold your loan. That tells you something about their long-term commitment beyond the rate itself.

Compare effective rates, not base rates alone. A SOFR-based loan with a 5.5% spread might produce a similar initial rate to a Prime-based loan with a 2.5% spread. The difference shows up over time. Run scenarios for both rate increases and decreases across a 10-year horizon.

Understand adjustment mechanics. SOFR-based rates can adjust monthly. Treasury rates use the final business day of the prior month. Prime changes only when the Fed moves. More frequent adjustments create more payment variability. Some borrowers will prefer Prime's relative stability.

Don't restart your lender search over this. Ronald Edmonds of Principium Group has observed that inexperienced lenders can take 90-120 days to close versus 45-60 for experienced ones. A lender offering alternative base rates who can't close on time isn't worth the marginal rate benefit.

Questions to Ask Your SBA Lender Before Signing

The bigger picture#

This change matters more for the SBA lending market than for any individual deal. By allowing lenders to use the same indexes they already use for conventional commercial loans, the SBA removes a friction point that kept some banks from participating in 7(a) lending. More participation means more competition, and that benefits borrowers.

The immediate opportunity is narrow: portfolio lenders who already use SOFR or Treasury rates can now extend that same pricing to SBA loans. But if secondary market eligibility follows - and the SBA has signaled it's evaluating demand - this could reshape how 7(a) loans get priced within a few years.

For now, treat this as one more reason to include portfolio-oriented lenders in your search. Ask the question. You might find options available starting March 1 that weren't on the table before.
