Have U.S. consumers gone “K-shaped”? A review of the data

Moody’s estimates spending by the top 10% rose 62% between Q3 2020 and Q3 2025, but Bank of America, the New York Fed, the BLS Consumer Expenditure survey, and a CE–PCE hybrid paint much smaller or mixed gaps. Bank of America card data show a split emerging in mid-2025 with the lowest tercile shrinking, the New York Fed finds nominal spending growth since 2020 of ~29% (low) to ~36% (high), the CE shows the top 10% accounted for 23% of out‑of‑pocket spending in 2024, and the prototype CE–PCE blend reports the top 10% at 25.7% in 2023. Conclusion: available measures diverge and do not coherently support a large, persistent K‑shaped consumption story.

Analysis

Fragmented consumption data creates a classic measurement asymmetry: different channels (card swipes, surveys, macro flows) weight households and categories unevenly, so headline narratives overstate conviction. That means positioning should lean on exposure to spending elasticity and balance-sheet leverage rather than on any single spending series; wealth-financed discretionary demand is mechanically more sensitive to equity and luxury-asset moves than to wage growth. Second-order sector effects will diverge: premium services and low-frequency high-margin goods can sustain pricing power with thin supply elasticity, while broad-based retail faces inventory and markdown risk if discretionary rotation stalls. Financial intermediaries that earn fees and interest on high-balance, high-turnover card relationships will capture upside in an uneven recovery, but also concentrate credit risk if lower-income households increasingly rely on unsecured credit. Catalysts that will quickly change the picture are clearer than the signal: a >=10% equity drawdown would transmit to luxury and travel demand within weeks, while tightening in unsecured lending standards or a visible uptick in delinquencies would compress bank earnings over a multi-quarter horizon. The prudent playbook is asymmetric: buy exposure to premium demand financed by balance-sheet-rich customers, hedge consumer-credit sensitivity, and use short-duration option structures to limit drawdowns tied to a rapid liquidity or wealth shock.
