Food Insecurity and Consumer Pessimism
Current discussions regarding a bifurcated U.S. economy highlight the increasing economic divide between lower- and higher-income Americans in spending and earnings growth and wealth accumulation. While many households are doing fine and economic activity overall has been expanding at a solid pace, large segments of the population are facing high levels of economic insecurity and financial strain, and consumer sentiment on the whole has dropped to low levels. In this post, we use newly collected data from the Survey of Consumer Expectations (SCE) to update our 2020 analysis of disproportionate financial hardship experienced during the early pandemic and to investigate recent changes in food insecurity and broader economic strains. We then examine how food insecurity relates to the increase in consumer pessimism. We find a remarkable increase in food insecurity, particularly among lower-educated and lower-income households and households with young children. We document a contemporaneous increase in pessimism among the same groups, along with a sharp decline in job-finding expectations.

AI’s Macroeconomic Challenges and Promises
In the third quarter of 2025, America’s largest tech firms for the first time spent more on capital investment than they earned from operations. The implication is that AI, a technology with the potential to make the economy more productive, is, for now, absorbing resources faster than it is generating returns. This post discusses how the tension between AI’s long-run promise and its short-run costs affects the outlooks for inflation, real activity, and financial stability.

The Global Credit Cycle in Corporate Bond Returns
The global corporate nonfinancial bond market is both a large investment asset class and a vital source of funding for nonfinancial firms. With $19 trillion outstanding at the end of 2024, a broad portfolio of corporate bonds would be expected to be well diversified. Yet, in 37 percent of months between 1998 and 2024, more than 80 percent of bonds in the ICE Global Bond Indices—a portfolio with over 10,000 constituents spanning diverse industries, credit ratings, and regions—moved in the same direction, suggesting a large degree of synchronization. In this post, we introduce the global credit factor, which proxies for the global price of risk in international corporate bond markets. The global credit factor creates a global credit cycle in bond risk premia and generates predictable comovement in bond prices.

Honey, Who Shrunk the U.S. Income Surplus?
Foreign holdings of U.S. financial assets are immense, with official estimates putting their current market value at $69 trillion. U.S. holdings of foreign assets are also impressive but much smaller, at $41 trillion. The shortfall in U.S. foreign assets relative to foreign liabilities has been mounting for decades. Yet U.S. investment income receipts—in profits, dividends, and interest—comfortably exceeded income payments until recently. We show that the fading of the net investment income surplus stems from the upward shift in interest rates in the aftermath of the pandemic along with the continued net sales of U.S. assets to foreign investors.

Will Mounting Supply Chain Strains Hamstring the AI Investment Boom?
The conflict in the Middle East has precipitated a global supply shock—the third in six years following the pandemic in 2020 and Russia’s invasion of Ukraine in 2022. The current shock raises the specter of spillovers to the U.S. through both prices and physical shortages of goods. A critical conduit for spillovers through these channels is via Asian supply chains, especially from middle- to lower-middle income countries in southeast Asia, which are key suppliers for goods needed for the AI infrastructure build-out in the U.S. These countries are also heavily reliant on Middle East energy imports. This post examines key factors related to these Asian supply chain vulnerabilities.

Same Shock, Different Roads? A K‑Shaped Pattern at the Pump
In March 2026, energy prices surged to a four-year high, driven by the Iranian closure of the Strait of Hormuz amid the ongoing conflict in the Middle East. In this Liberty Street Economics post, we use the new consumer spending module of the Economic Heterogeneity Indicators to analyze recent changes in nominal and real gas consumption across different income groups. We find that households had very different experiences with gasoline spending: in March, high-income households increased nominal spending the most and kept real consumption essentially unchanged, while low-income households decreased real consumption of gasoline but still saw sharply increased nominal spending because of the rise in gas prices. Therefore, with the sharp increases in gasoline prices in March, a K-shaped pattern in gasoline consumption emerged—showing faster consumption growth for high-income households relative to low-income households. These gasoline consumption patterns qualitatively match those following the increase in energy prices at the beginning of the Russia-Ukraine war in spring 2022, even though the gap in consumption trends during the current episode is quantitatively larger.

Explaining the K‑Shaped Economy: What’s Behind the Divide?
In our companion post, we used a new module of our Economic Heterogeneity Indicators (EHIs) to shed light on how recent retail spending growth has been driven by high-income households. This fact is consistent with the popular press’s idea of a “K-shaped economy” in which higher-income households experience faster growth in spending than lower-income households. In this post, we dive deeper into the reasons behind this divergence by analyzing for which goods this trend holds true and ask whether it can be explained by changes in wages, inflation, or wealth. We find that, since 2023, wealth has increased the most for high-income households, while inflation has risen the most for low-income households, with both factors helping explain the fact that real retail spending rose the most for high-income households. In contrast, earnings display a more mixed pattern, though earnings of the highest earners have grown more rapidly than earnings of the lowest earners.

Tracking the K‑Shaped Economy: Who’s Driving Spending?
Aggregate real consumer spending has risen solidly since 2023. However, it is less clear how widely shared this improvement has been across all segments of society. This is important because systematic heterogeneity may mask the dependence of aggregate growth on a relatively small group of households and thus conceal macroeconomic risks. In this post, we use consumer spending data recently added to the Economic Heterogeneity Indicators (EHIs) and find that retail spending growth has been driven by high-income households—those earning more than $125,000 per year. In the popular press, the phenomenon of higher-income households growing at a faster rate than lower-income households has been referred to as the K-shaped economy. We find that consumption has exhibited a K-shaped economy since 2023, although not in the pre-COVID period or during the post-COVID recovery.

Bank Failures: The Roles of Solvency and Liquidity
Do banks fail because of runs or because they become insolvent? Answering this question is central to understanding financial crises and designing effective financial stability policies. Long-run historical evidence reveals that the root cause of bank failures is usually insolvency. The importance of bank runs is somewhat overstated. Runs matter, but in most cases they trigger or accelerate failure at already weak banks, rather than cause otherwise sound banks to fail.

Use of Gen AI in the Workplace and the Value of Access to Training
The rapid spread of generative AI (AI) tools is reshaping the workplace at a remarkable rate. Yet relatively little is known about whether workers have access to these tools, how the tools affect workers’ daily productivity, and how much workers value the training needed to use the tools effectively. In this post, we shed light on these issues by drawing on supplemental questions in the November 2025 Survey of Consumer Expectations (SCE), fielded to a representative sample of the U.S. population. We find that adoption of AI tools at work is heterogeneous, that a sizable share of workers see AI training as important, and that a significant share of employers are nonetheless not yet providing access to AI tools or training on how to use them.
