Why car prices won’t stop rising

Average new-car transaction prices, which briefly topped $50,000 in September, are expected to climb back above that threshold as model-year 2026 vehicles with higher stickers enter lots and dealers shift mix toward pricier trucks/SUVs; Edmunds reported a roughly 4% rise in September and October. The Trump administration announced a rollback of Biden-era fuel-economy rules and removal of EV tax-credit/penalty provisions, with claims of ~$1,000 in consumer savings, but analysts say the policy shift is unlikely to meaningfully reduce automakers’ costs or consumer prices in the near term. With ~80% of purchases financed and nearly 20% of new-car buyers facing monthly payments of $1,000+, prospective Fed rate cuts could lower interest costs yet leave dealers room to raise prices, while a significant jobs downturn remains the clearest downside risk to demand.

Analysis

Market structure: Higher average transaction prices (ASP) favor manufacturers and dealers that sell trucks/SUVs and can preserve gross margins (Ford, Stellantis). Winners include dealers, captive finance arms and parts suppliers (steel, semis); losers are low‑margin compact/EV pure‑plays and residual‑dependent lessors if used prices normalize. Expect ASPs to rise ~3–6% into H1 2026 as 2026 models mix in.

Competitive dynamics & supply/demand: The rollback of penalties and end of EV buyer credits accelerates mix shift to profitable ICE trucks/SUVs, widening spread between margin-rich pickups and low-margin electrics. Demand remains income-sensitive: a 0.5%–1.0% rise in unemployment or a 10% drop in used-vehicle CPI would materially compress volumes and force price cuts. Inventory replenishment cycles (dealership aging and lease returns) are the key supply signal over the next 3–9 months.

Cross-asset and tail risks: Expect knock-on effects to rates and credit spreads — stronger ASP/loans support ABS issuance but a recession would spike auto ABS delinquencies and widen IG/High-yield spreads. Fed rate cuts (priced by futures over 6–12 months) could lower borrowing costs but enable dealers to raise nominal prices; converse, a sharper slowdown is a bankruptcy tail risking supplier outages and equity downside of >30% in stressed OEMs.

Catalysts & monitoring: Trade around three datapoints: monthly new-vehicle sales and average transaction price, used-vehicle CPI, and unemployment + Fed funds futures. Legal challenges from states (California standards) and Q4 2025/2026 earnings commentary are binary catalysts that can re-rate shares within weeks of announcements.

Key Decisions for Investors

• Establish a 2.5% long position in STLA (Stellantis) for 6–12 months: thesis is higher ASP from SUVs/pickups and favorable political messaging; use a 3% trailing stop and trim to half if monthly new-vehicle ASP growth falls below +1% YoY for two consecutive months.
• Establish a 2% long position in F (Ford) via a 3–6 month call spread (buy ATM, sell +20% OTM) to capture upside from truck demand and captive finance margins; unwind if auto loan 30+ day delinquencies rise by >25% QoQ or if unemployment increases >0.5pp in one month.
• Take a 2% short/hedge on GM (GM) via buying 6‑month 10% OTM puts (or short equity) to express risk from EV capex and margin pressure; cover if GM guidance tightens or if management announces >$2bn of margin-supporting cost cuts.
• Buy a 0.5% allocation to 9–12 month protection via long auto ABS CDS or put spreads on an auto OEM basket if used-vehicle CPI drops >8% YoY or if Fed funds futures push out first cut beyond 12 months — this acts as macro downside insurance.
