Younger Americans turn to riskier investments, spend more on nonessentials as homeownership dreams fade: study

A study by Northwestern and the University of Chicago finds a sharp decline in U.S. housing affordability since 2020 and projects that the cohort born in the 1990s will reach retirement with a homeownership rate roughly 9.6 percentage points below their parents. The authors show that falling perceived probabilities of homeownership push lower-wealth renters to spend more on credit cards, reduce work effort and increase participation in cryptocurrency markets, and recommend targeted subsidies to keep more young renters attempting to buy homes; mortgage rates have eased about 70 bps from the 2025 high (≈150 bps from the 2023 peak), which has modestly improved near-term affordability.

Analysis

Market structure: Lower expected homeownership disproportionately helps nonbank consumer incumbents (Visa MA, Discover DFS) and digital platforms (Coinbase COIN, Square SQ, Affirm AFRM) because renters shift discretionary spend to credit and crypto; losers are homebuilders (ITB, DHI, PHM), building-materials suppliers and mortgage-originators as structural demand for mortgages falls by an estimated ~9–10ppt for 1990s cohort over their lifetime. Pricing power shifts toward payments networks and online retailers while housing-related spreads (MBS, RMBS) widen; inventory tightness persists until 30yr fixed rates decline materially below ~5.5%.

Risk assessment: Key tails — a targeted subsidy for first-time buyers (federal/state) could lift home construction volumes sharply (positive shock to ITB and lumber/EXH names) while a regulatory crypto clampdown would crush COIN and spot crypto demand. Near-term (days–weeks) sensitivity is to mortgage-rate headlines and delinquencies; medium (3–12 months) to credit-loss trends and policy interventions; long-term (years) to cohort wealth divergence and lower lifetime mortgage origination. Hidden dependency: low churn from legacy low-rate mortgages suppresses supply even if buyer demand returns.

Trade implications: Favor overweight payments and select retail exposure for 3–12 months (MA/V/AMZN) and underweight homebuilders and mortgage REITs (ITB, NLY, AGNC). Implement volatility-managed option hedges: buy 6–9 month COIN call spreads (convex exposure to higher retail crypto participation) while hedging regulatory risk with OTM puts. Pair trade: long payments vs short homebuilders to capture relative earnings resiliency.

Contrarian angles: Consensus may underprice policy risk — a well-targeted subsidy (authors' proposal) would be a multi-quarter positive for builders and MBS; appropriate sized, hedged long ITB is a convex contrarian. Also higher unsecured lending could boost fee income but raise credit-cycle exposure; consider credit-default and card delinquency screens before levering consumer names.

Key Decisions for Investors

• Establish a 2–3% portfolio long split between Mastercard (MA) and Visa (V) (≈1–1.5% each) with a 6–12 month horizon to capture higher card spend from renters; trim if quarterly card delinquencies rise >50bps or if consumer discretionary same‑store sales miss by >3%.
• Initiate a 1.5–2% hedged short on homebuilders via ITB — implement as a 3–6 month put spread (buy 15–20% OTM put, sell 5–10% OTM put) or a small outright short; exit/flip long if 30yr mortgage <5.5% sustained for 6 weeks or FHFA/HUD announce targeted first‑time buyer subsidy.
• Allocate 0.75–1% to a 6–9 month COIN call spread (limit max loss to ~1% portfolio) to capture elevated retail crypto participation; cap position and buy 2–3% OTM puts as insurance against regulatory announcements within 90 days.
• Short mortgage REITs (NLY, AGNC) for 1–2% exposure given margin and rate volatility — prefer short via options or tight stop-loss; de-risk if 10yr Treasury yield drops >50bps from current level.
• Execute a relative-value pair: long 1.5% MA vs short 1.5% ITB (equal notional) to express payments resilience vs housing weakness over 3–9 months; rebalance if house-price index (Case‑Shiller/Redfin) shows >5% YoY appreciation or mortgage rates breach the 5.5% threshold downward.
