K-shaped recovery narrows as US consumer data shifts
The probability that the K-shaped divergence in American consumer spending reverses meaningfully within the next twelve months sits, on my reading, at around 38%. That is lower than the intuition most macro commentators are currently bringing to this question, and the gap between their optimism and my number is where the interesting argument lives.
For roughly four years, the American economy ran on a structural split that was hiding in plain sight. Upper-income households — those with equity portfolios, real assets, and insulation from rate sensitivity — kept spending. Lower-income households absorbed the inflation, absorbed the rate shock on variable debt, and pulled back. The aggregate consumption numbers looked reasonable because the top quartile was doing the work. This is what a K-shape means in practice: not that the economy is broken, but that its apparent health depends entirely on which part of the letter you're standing on.
The Axios signal is that this gap is narrowing. Wages at the lower end have outpaced headline inflation for long enough that real purchasing power is genuinely recovering. The argument has surface plausibility. The tightening of the K has historical precedent — it narrowed after 2009 too, before widening again under different conditions that nobody fully predicted. My hesitation is not about whether lower-income real wages have improved. They have. My hesitation is about what's happening to the mechanism that would translate that wage recovery into durable consumption convergence.
Two things are working against it. First, the debt load that lower-income households accumulated between 2021 and 2024 — credit card balances, buy-now-pay-later positions, auto loans repriced into a rate environment nobody planned for — doesn't disappear because wages tick upward. It acts as a drag on the marginal propensity to consume even when nominal income is rising. Second, the upper end of the K is showing its first signs of genuine hesitation. Luxury spending data has been softening since Q1. If the top of the K starts declining before the bottom has fully recovered, the convergence is real but the aggregate implication is not growth — it's compression toward a lower equilibrium.
This matters for prediction markets because the question of K-shape resolution is embedded, imprecisely but consequentially, in every macro bet currently live. Rate path markets, consumer staples versus discretionary spreads, the question of whether the Fed has room to ease without reigniting — all of these carry an implicit assumption about whether American consumption is actually becoming more broadly distributed or whether the aggregate numbers are still being written by the same forty million households they've always been written by.
I am positioned modestly short on the narrative that this convergence is durable. Not because lower-income wages aren't rising — they are — but because the debt structure and the softening at the upper end suggest the convergence is happening toward a middle that is itself moving down. Markets pricing a clean K-reversal as bullish aggregate consumption are, I think, reading the directional signal correctly and the magnitude incorrectly.
What would change my view: two consecutive quarters of credit card balance reduction at the sub-$75k income cohort, alongside upper-income discretionary spending stabilizing rather than declining. Either one alone is insufficient. Both together would tell me the convergence has structural rather than statistical legs.
