Recent disruptions to global oil markets, from Russia’s invasion of Ukraine to the war in Iran, have revived fears of stagflation. This column shows that the shale revolution has fundamentally changed how the US economy responds to oil shocks. As the country has shifted from a major petroleum importer to a net exporter, adverse oil supply news has become considerably less contractionary and can even support activity, with benefits extending beyond the oil sector. The findings suggest that the Federal Reserve faces a more favourable trade-off between activity and inflation, even as households and firms remain exposed to higher energy costs.
The war in Iran and the disruption of oil shipments through the Strait of Hormuz have placed global energy markets under considerable strain. While inventories, emergency reserve releases, and the rerouting of trade flows have helped cushion the initial supply shortfall (D’Orazio et al. 2026), these buffers are temporary. As the disruption persists, fears of stagflation are growing.
These concerns are rooted in historical experience. Hamilton (1983) famously documented the close relationship between oil price increases and US recessions. The oil crises of the 1970s, the Iran–Iraq War, and the invasion of Kuwait all cemented the view that adverse oil shocks pose a major threat to the economy. More recently, however, this pattern appears to have weakened. The oil market disruptions surrounding the Arab Spring in 2011 and Russia’s invasion of Ukraine in 2022 were not followed by US recessions. Has the US economy become less vulnerable to oil shocks? Previous research has documented changes in the effects of oil shocks, but the evidence on their magnitude and underlying drivers remains mixed (Blanchard and Galí 2010, Baumeister and Peersman 2013, Baumeister and Kilian 2017, Bjørnland and Skretting 2024).
In new research, we revisit this question with nearly a decade of additional data, examining how the US economy’s response to oil shocks has evolved (Känzig et al. 2026). We show that adverse oil supply shocks have become considerably less contractionary and can even stimulate economic activity, a shift closely linked to the US petroleum trade balance. The improvement extends beyond the oil sector: more favourable terms of trade, stronger consumption, and higher equity valuations point to broad-based income and wealth effects that support activity across sectors and regions.
The shale revolution fundamentally altered the US energy landscape. Advances in horizontal drilling and hydraulic fracturing led to a dramatic expansion in domestic oil production. As Figure 1 shows, US crude oil production rose from around five million barrels per day in the late 2000s to almost 14 million by 2025, while net imports of crude oil and petroleum products declined sharply and turned negative in 2019. Although the US remains exposed to global oil prices and continues to import substantial quantities of crude oil, its overall petroleum trade position has reversed.

This matters because an oil-price increase redistributes income. For a net importer, more national income is transferred abroad to pay for energy. For a net exporter, higher export prices can instead bring additional profits, wages, investment, and tax revenues home. Whether these gains outweigh higher costs for energy users is ultimately an empirical question.
Not every oil price increase has the same economic consequences. Prices can rise because global demand is booming or because expected oil supply has fallen. Confusing these sources can distort conclusions about oil shocks (Kilian 2009, Baumeister and Hamilton 2019). The challenge is therefore to isolate changes in oil prices that are genuinely driven by supply developments rather than demand.
We use changes in oil futures prices around OPEC production announcements to measure unexpected news about future oil supply, building on Känzig (2021). Since these announcements occur on known dates, economic conditions are largely reflected in market prices beforehand. To the extent that no other relevant news arrives at the same time, movements in futures prices around the announcements capture unexpected revisions to anticipated oil supply. We use these announcement surprises to identify oil supply news shocks in a model of the global oil market. We then estimate state-dependent local projections that allow the effects of these shocks on the US economy to vary with its petroleum trade position, measured by net petroleum imports relative to domestic petroleum consumption. In this way, we can directly assess how the transmission of oil shocks changes as the US moves towards exporter status.
Allowing the US response to evolve over time reveals a pronounced change. Figure 2 shows the estimated responses at the average petroleum trade positions before 2010 and in 2025, for an adverse oil supply shock that raises the real oil price by 10% on impact at the pre-2010 position. Before the shale revolution, oil shocks were recessionary: industrial production falls by about 0.6% after a year. Moving to the 2025 position improves the response by roughly 1.5 percentage points, turning the contraction into an expansion. Employment and unemployment responses also become markedly more favourable.

The contrast for inflation is much smaller. Consumer prices still rise following adverse oil supply news, but their response changes little with the US petroleum trade position. The US thus faces a more favourable output–inflation trade-off. These findings are robust to accounting for other secular and structural changes over this period, including the declining energy intensity, the expanding services sector, changes in manufacturing employment, and periods of exceptionally low interest rates.
One explanation is a mechanical improvement in net exports. Yet although the US terms-of-trade response changes from a deterioration to an improvement, the estimated change in aggregate net exports is modest. The large shift in activity cannot be explained by national accounting alone.
Another possibility is that the gains to oil-producing sectors and regions increasingly outweigh losses elsewhere in the economy. Employment in oil and gas extraction indeed responds much more strongly than before the shale boom. Yet the benefits are considerably more broad-based. Across sectors, employment responses become more favourable in manufacturing, construction, trade, and services. Across regions, total employment improves by similar amounts in oil-producing and non-oil-producing states. The improved aggregate response therefore cannot be explained simply by gains in oil-producing industries or regions offsetting losses elsewhere.

Instead, the evidence points to broader income and wealth effects. More of the gains from higher oil prices accrue domestically and can sustain spending throughout the economy. Figure 3 shows that real household consumption, which used to decline after an adverse supply shock, rises at the 2025 petroleum trade position. The improvement is especially apparent in spending other than food and energy. Equity valuations show a similar reversal: the S&P 500 response changes from negative to positive, reaching around 2% at its peak. Even airline and transportation stocks, despite their direct exposure to fuel costs, respond more favourably.
Nor is the stronger economy explained by a more accommodative Federal Reserve. One-year interest rates respond somewhat more forcefully as the US moves towards exporter status. This is consistent with an economy that can absorb oil-related inflationary pressure without the same contraction in activity.
The oil-price surge following Russia’s invasion of Ukraine in 2022 illustrates the quantitative importance of this change. We first calculate the gap between the realized path of real oil prices and a forecast made before the invasion. We then recover the sequence of oil supply news shocks needed to reproduce this gap and examine how the same shocks would have affected the US economy at the average pre-2010 petroleum trade position and the 2021 position.

Figure 4 reveals sharply different outcomes. At the historical importer position, the episode would have reduced US industrial production by around 1%. At the 2021 position, the central estimate instead implies an expansion exceeding 1% at longer horizons. Consumer prices rise in both scenarios, although the increase is initially smaller but more persistent at the 2021 position. The one-year Treasury rate also responds more strongly at the 2021 position.
This counterfactual exercise illustrates how the same oil price episode can have very different macroeconomic consequences depending on the US petroleum trade position. We attribute the entire deviation of oil prices from their pre-invasion forecast to oil supply news, even though other factors may also have contributed to the 2022 price surge. Still, the exercise helps explain why large oil price increases need no longer generate the recessionary dynamics familiar from earlier decades.
Our findings do not imply that higher oil prices are beneficial for every US household or firm. Motorists still face higher fuel bills, and energy-intensive industries continue to confront higher production costs. Nor does net exporter status insulate the US from global oil markets: adverse oil supply shocks still put upward pressure on consumer prices. Rather, the shale revolution has changed the balance of aggregate gains and losses, with more of the income generated by higher oil prices accruing domestically and supporting spending and activity across the economy.
More broadly, our results show that the macroeconomic consequences of global commodity shocks depend critically on an economy’s production and trade structure. For policymakers, this means looking beyond the direct effects of higher energy prices on production costs and purchasing power to consider the broader general-equilibrium effects operating through income and wealth. As the US experience illustrates, these indirect effects can fundamentally alter the consequences for economic activity, even as inflationary pressures persist.
