Why Your Wallet Isn't Riding the Stock Market Boom

The S&P 500 is up nearly 13 percent this year, a surge largely attributed to the artificial intelligence investment boom. Many economists and market watchers have a simple, slightly cynical explanation for why the US economy is still humming despite high interest rates. They believe the wealth effect is doing the heavy lifting. In their view, the top 10 percent of earners are seeing their portfolios swell, and that paper wealth is translating into real spending on luxury goods, travel, and dining. If this theory were true, the data should show a massive divergence in spending habits between the rich and everyone else.

Chicago Federal Reserve president Austan Goolsbee disagrees with that narrative. In a recent interview with Yahoo Finance, he pushed back against the idea that the stock market is propping up the US economy. He pointed to a different reality, one where consumer spending is strong across the board, not just at the top end. Goolsbee noted that it is very hard to have such robust spending numbers without it being broad-based. This challenges the prevailing wisdom that the current economic resilience is a fragile house of cards built on equity gains.

The Data Behind the Claim

Goolsbee’s argument rests on hard numbers from the Bureau of Labor Statistics. The bottom 90 percent of the income distribution accounts for roughly 75 percent of all spending in the US economy. That is a massive share of the pie, and if the stock market were the primary engine of consumption, we would expect to see this group lagging significantly behind the wealthy. Instead, the data tells a story of steady, widespread participation in the economy. The spending power is not concentrated in a few pockets of wealth; it is distributed across millions of households.

Recent statistics from the New York Federal Reserve reinforce this point. The data shows that cumulative real spending growth over the past three years has remained remarkably similar across all income tiers. The gap between high-income and low-income consumers has been a mere one percentage point. This is not a bifurcated economy where one group is feasting while another is starving. It is a unified front of consumption that is driving the macroeconomic indicators. The consistency of this data over three years makes it difficult to dismiss as a temporary anomaly or a statistical fluke.

The Counter-Argument from the Beige Book

However, the picture is not entirely black and white. The Federal Reserve’s Beige Book, which compiles anecdotal evidence from the central bank’s 12 regional districts, paints a more nuanced and sometimes contradictory picture. Over half of the districts reported that consumer spending is indeed being driven by high-income households. This suggests that while the broad trends look healthy, the micro-level reality can be more uneven. In some regions, the wealthy are carrying the local economy, while lower-income consumers are tightening their belts.

Even in Dallas, where companies reported solid retail sales, there were reports of lower-income customers being more cautious with their spending. This highlights the tension between the macro data and the local experience. A consumer in a high-cost-of-living area might be feeling the pinch of high rents and interest rates, even if their spending category shows up as stable in the aggregate numbers. The Beige Book serves as a reminder that economic data is an average, and averages can hide significant variation in individual experiences.

The AI Bubble Warning

Goolsbee did issue a warning, however, about the speculative nature of the current market. He cautioned that the intensifying hype around AI and its future potential could push up stock valuations to unsustainable levels. This creates a risk where consumers might feel wealthy on paper and start spending money they do not actually have. This is a classic sign of a bubble, where asset prices drive behavior in ways that are not supported by underlying fundamentals. If the AI boom were to stall or reverse, the wealth effect could evaporate quickly, leaving consumers with a sudden drop in perceived income.

The danger is not just in the stock market itself, but in how it bleeds into the broader economy. If consumers are making purchasing decisions based on the value of their portfolios rather than their cash flow, they are vulnerable to a sharp correction. Goolsbee’s warning is a reminder that the current strength in spending, while broad-based, may be more fragile than the data suggests. The market is providing a buffer, but if that buffer is built on speculation, it could vanish overnight.

What This Means for Investors

For investors, this debate has significant implications. If Goolsbee is right, the US economy is more resilient than the bearish case suggests. Consumer spending is not dependent on the stock market, which means a correction in equities might not trigger a recession. The economy has its own momentum, driven by broad-based spending. This is a bullish signal for the overall health of the US economy, and it suggests that companies are not overly reliant on the wealth effect to drive revenue.

On the other hand, if the Beige Book is more accurate, the economy is more fragile than it appears. The reliance on high-income spending means that a drop in equity values could have a disproportionate impact on consumption. This would be a bearish signal, suggesting that the economy is more sensitive to market fluctuations than the macro data indicates. Investors need to keep an eye on both the broad trends and the local signals to get a complete picture of the economic landscape. The truth likely lies somewhere in between, but the debate itself is a crucial part of understanding the current market environment.
