J.D. Power March 2026: SAAR Holds at 16.0M, But the Negative Equity Bomb Is Ticking
[DEEP DIVE] New-Vehicle Sales / Affordability
March's headline numbers look clean. J.D. Power and GlobalData pegged total SAAR at 16.0M units, retail volume hit the highest monthly total of 2026, and the full-year forecast didn't budge. But underneath that surface, a structural affordability problem is compounding — and the dealers who aren't seeing it yet are the ones who will feel it hardest.
The Headline Numbers
March retail sales landed at 1,120,601 units— the strongest retail month of the year so far — and J.D. Power held its full-year 2026 forecast at 16.3M units, signaling ongoing industry resilience. Average retail transaction prices climbed to $45,859, up 2.5% year-over-year, while incentive spend reached $3,325/unit — up $165 YoY — with non-BEV discounts running at 6% of MSRP, up $353 YoY. Average new-vehicle loan rates dropped to 6.55%, down 36 basis points year-over-year, providing modest payment relief. What's holding up: retail volume and a flush inventory base of 2.22M units, up 4.5% YoY. What's fragile: the buyer profile underneath those transactions is increasingly stretched.
The Negative Equity Time Bomb
30.5% of trade-ins now carry negative equity — up 4.2 percentage points year-over-year, and that number has a specific origin story: the buyers who paid peak prices during the inventory shortage four years ago are cycling back into the market now. They overpaid, depreciation has run its course, and they're showing up at your trade desk with a problem you have to solve before you can desk a deal. The average underwater trade carries $7,214 in negative equity — an all-time high per Edmunds Q4 2025 data — and 27% of those trades exceed $10,000 in negative equity. When that deficit rolls into a new loan, the payment becomes unworkable: buyers who rolled negative equity into a new vehicle averaged $916/month in Q4 2025 — a record high, $144 above the market average. That's not a payment a rate buydown fixes. That's a structural problem requiring a structural solution.
The 84-Month Trap
84-month terms now represent 12.5% of all financed deals, and 40% of negative-equity new-car transactions are being financed at 84 months. Dealers are stretching terms to compress the monthly payment — it works today, it manufactures tomorrow's problem. The buyer who signs a seven-year note in 2026 will be back at your trade desk in 2028 or 2029 with a car worth less than what they owe, and the cycle continues. Every 84-month deal written today on an underwater trade is a future negative equity case waiting to land.
The Lease Comeback: The Real Affordability Answer
Lease payments are currently running approximately $120/month cheaper than equivalent loan payments — a spread that hasn't existed at this magnitude since before the inventory crisis. OEM-supported subvented rates — the 0% and 1.9% programs that disappeared for the better part of five years — are returning as manufacturers prioritize volume and affordability. Leasing solves the negative equity problem structurally, not cosmetically: the buyer gets into a controlled payment, the residual is guaranteed by the OEM, and at lease end they walk away without an underwater position. J.D. Power's Tyson Jominy has flagged the lease payment gap as a legitimate market signal. Dealers who are actively presenting lease as the primary payment solution — not as a fallback — are ahead of the curve on this one.
What This Means for Your Store
Start every deal with a hard payoff pull before you desk anything — if the trade is underwater, you need to know the magnitude before you've committed to a structure. On underwater trades above $5,000, run LTV calculations against available lease programs before presenting a purchase alternative; in many cases the lease pencils cleaner and protects the customer from digging deeper. F&I needs to be in the conversation earlier than usual right now: at $916/month for rolled-equity buyers, there is very little room for backend product stacking on purchase deals, so backend revenue strategy has to shift toward lease-based protection products and GAP on the remaining purchase deals. Used car managers should be pricing aggressively on trades with significant negative equity — what you give to solve a deal has to be defensible at auction. Finally, identify which of your OEM partners are running the strongest lease support right now; with subvented programs returning across multiple brands, the variable is which captives are offering the best residuals and the deepest rate support. That's where your sales floor's energy belongs.
