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 ...

The Regional Side of the Story: K‑Shaped Pattern in Region, Wider Gap in Gas Spending
In this post, we use the inaugural release of our regional consumer spending indicators to ask whether these patterns hold for a significant portion of the Second District, and how regional spending patterns by income have been similar to or different from the national patterns we documented earlier. We find similar K‑shaped patterns in both retail and gas spending in our region as we do in the nation, with the K‑shaped pattern in gasoline in response to the recent gas price shock being more pronounced in the region.

Regional Gasoline Price Dynamics
A large literature has argued that gasoline prices respond more rapidly to increases in oil prices than to decreases in oil prices. Moreover, some of this literature has found heterogeneous asymmetry in gas price responses across cities. Here, we reconsider the causes of heterogeneous asymmetric pass-through. Consistent with the previous literature, we find heterogeneity in the magnitudes of asymmetric pass-through across cities. We also find a large number of cities that exhibit no asymmetries. We then examine whether heterogeneous asymmetry results from city-level differences in (i) the ...

Heterogeneity in the Pass-Through from Oil to Gasoline Prices: A New Instrument for Estimating the Price Elasticity of Gasoline Demand
We propose a new instrument for estimating the price elasticity of gasoline demand that exploits systematic differences across U.S. states in the pass-through of oil price shocks to retail gasoline prices. We show that these differences are primarily driven by the cost of producing and distributing gasoline, which varies with states’ access to oil and gasoline transportation infrastructure, refinery technology and environmental regulations, creating cross-sectional gasoline price shocks in response to an aggregate oil price shock. Time-varying estimates do not support the view that the ...
Implications of the Iran war for U.S. inflation
Recent research quantifies the impact of 2026 Iran war on U.S. inflation and household inflation expectations under a range of scenarios. Under a plausible scenario, 2026 fourth-quarter-over-fourth quarter headline personal consumption expenditures inflation would increase by 0.6 percentage points.

U.S. gasoline imports rise following temporary easing of fuel standards
EPA fuel standards were temporarily waived following major Gulf Coast hurricanes in 2005 and 2008, including Katrina. The results suggest that more uniform environmental standards could help foreign refiners meet extraordinary U.S. gasoline demand.

Can Higher Gasoline Prices Set Off an Inflationary Spiral?
In early 2022, with consumer price inflation already high, a spike in the price of gasoline increased public concerns that the U.S. economy could be in for a repeat of the inflationary spiral that gripped the nation in the 1970s and 1980s. During this period, energy price increases created an environment where rising inflation and rising inflation expectations reinforced one another until a deep economic contraction broke the feedback loop.Nida Çakır Melek, Francis M. Dillon, and A. Lee Smith assess the risk of a similar spiral in the current environment by exploring whether high inflation ...

A Broader Perspective on the Inflationary Effects of Energy Price Shocks
Consumers purchase energy in many forms. Sometimes energy goods are consumed directly, for instance, in the form of gasoline used to operate a vehicle, electricity to light a home or natural gas to heat a home. At other times, the cost of energy is embodied in the prices of goods and services that consumers buy, say when purchasing an airline ticket or when buying online garden furniture made from plastic to be delivered by mail. Previous research has focused on quantifying the pass-through of the price of crude oil or the price of motor gasoline to U.S. inflation. Neither approach accounts ...
