The pattern tracks the gas pump almost exactly. Sentiment climbed from May's record low to 55.2 in July as fuel prices backed off their spring peak. Then fuel came back. September set a record for the month, and this is the first October on record with the national average above $4 a gallon. Michigan's index fell in August, again in September, and again in the early October read. Year-ahead inflation expectations are back up to 4.7%.

The Conference Board's measure tells the same story with a harder edge. It dropped 6.7 points in September to 81.9, its lowest reading since 2014, and consumers' view of current business conditions turned negative for the first time in two years. The expectations component fell to 63.6, well under the 80 line the Board treats as a recession warning.

Behind both surveys is a job market that has quietly stalled. September payrolls grew by 29,000, July now shows a loss, and the three-month average is about 51,000 a month. Wage growth slowed to its weakest pace since 2021. People don't stop buying cars because a survey says they're gloomy. They stop when they're worried about the paycheck, and that worry is now showing up in the data that matters.

The delinquency picture says the stress is real, but it's concentrated. The New York Fed's second-quarter report showed auto balances up $28 billion to $1.71 trillion, and the flow of auto debt into early delinquency ticked up while overall household delinquency eased. Fitch's subprime index set its all-time high at the start of the year. Prime borrowers, by comparison, are still running delinquency rates well under 1%.

Banks aren't pulling back yet. In the Fed's July loan officer survey, lenders said auto standards were basically unchanged while demand for auto loans weakened. That's the combination to watch. When lenders see demand soften and losses climb at the same time, tightening usually follows, and it usually starts at the bottom of the credit stack.

Then there's the Fed itself. September's hike took the funds rate to 3.75% to 4.00%, and the median projection implies one more quarter point before year end. Auto loan rates follow longer-term Treasury yields more than the overnight rate, so a December hike won't hit retail APRs one for one. It does land right in the middle of your biggest month and gives every lender one more reason to price for risk.

Read the consumer side first. Headline inflation at 3.7% is almost entirely an energy story: gasoline is up a third from a year ago and the energy index is up a fifth. Strip that out and core inflation is 2.6%, close to where the Fed wants it. New-vehicle prices are up just 0.6% over the year, which matches the 0.8% sticker increase Kelley Blue Book reported, and used-vehicle prices are below a year ago. If you only looked at the retail price of a car, you'd say inflation isn't the industry's problem.

Now read the producer side. Prices for final demand rose 1.3% in September alone and 6.3% over the year. The index for processed goods bound for intermediate demand, which is where steel, aluminum, resins and components live, is up 14.1% over the year and accelerating. That gap between a 14% rise in inputs and a 0.6% rise in the price of a finished vehicle is being eaten somewhere, and the somewhere is manufacturer margin.

This is the missing piece in our July incentive call. We expected manufacturers to put money on the hood in the second half. They didn't, and the producer data says why: with tariffs and materials pushing cost up double digits while the market refuses a sticker increase, there isn't spare margin to fund incentives. Incentive spending has been stuck between 6.5% and 6.6% of transaction price since July. Expect that restraint to carry into December, with money targeted at slow-moving model-year 2026 units rather than spread across the lineup.

Wholesale prices ran ahead of normal for most of the year, then reversed. The Manheim index fell to 205.9 in September, 0.6% below a year ago and the first year-over-year decline of 2026. Depreciation came in faster than the season usually brings, helped along by high fuel prices, higher rates, and a September with no Atlantic hurricane for the first time in decades. Storms usually put a floor under used values in the fall. This year nothing did.

The damage isn't even. In mid-September, compact cars were holding 5.1% above last year while pickups were down 2.0% and SUVs and crossovers were down 3.3%. Electric vehicles are one of the few segments still above last year, up 4.3% in September, as gas prices push used shoppers toward anything that doesn't need a fill-up.

Now lay that against the trade side. Nearly three in ten trade-ins toward a new vehicle were already underwater in Q2, by an average of $6,884, and buyers rolling that debt into a new loan were paying a record $944 a month. A lot of those trades are 2022 purchases made at peak prices with little or no discount. Every point of depreciation between now and December widens the gap you have to cover to make the deal work, and trucks and SUVs, the segments falling fastest, make up a big share of what comes across most appraisal lanes.

One thing argues the other way, and it matters for how long this lasts. Leasing has fallen to about 19% of retail, and it was weak through 2023 and 2024 as well. That means the off-lease supply that normally refills the two-to-four-year-old used market in 2027 and 2028 will be thin. Near-term, values are sliding on fuel, rates and a weak consumer. Beyond the next couple of quarters, the supply picture puts a floor under late-model used values. Don't confuse a Q4 correction with a structural collapse, and don't dump good two-year-old inventory to chase it.

Third-quarter volume came in around 4.09 million units at a 16.4 million pace. September slipped to 16.0 million, down 3.6% from a year ago, though that comparison is muddied. Last September was inflated by buyers rushing to beat the end of the federal EV credit, and Labor Day weekend landed in a different reporting month. On the forecast side, Cox now sees 16.1 million for the full year, with retail at 13.1 million and fleet at 3 million. JD Power opened the year at 16.3 million and held that number through the spring. NADA expects the market to meet or beat 16 million.

We're moving our fourth-quarter call up from July, but not all the way to consensus. Here are the three paths we're planning around.

One mix note before the playbook. Hybrids are where demand is going, and fast. They're 15.6% of new sales through September, and JD Power had them at 17% of retail sales in September alone. Battery-electric share has fallen to 6.2% now that the federal credit has been gone a full year. If you can get hybrid allocation, it's the inventory that sells itself this winter.
