Energy Shock Fails to Dislodge Core Inflation Expectations From 2% Target
US core CPI held at 2.9% annually in May despite a 23.5% surge in energy prices, and bond markets have broadly followed that signal even with crude near $95 and European gas above €70.
ICE Brent crude front-month held at $94.97 a barrel as of September 6 (2026-09-06), with markets closed for the weekend, while ICE Endex TTF front-month was last recorded at €71.95/MWh. Both prices remain well above levels seen before Iran-linked hostilities disrupted oil and gas flows earlier this year. Bond markets and policymakers in the United States and Europe appear, at least so far, to have treated the energy price rise as a pass-through phenomenon rather than a sign of entrenched inflation.5
The US data from May 2026 (2026-05) gives the clearest empirical basis for that view. The Bureau of Labor Statistics reported that the Consumer Price Index rose 4.2% annually — the highest since April 2023 and an acceleration from 3.8% in April. Energy prices jumped 3.9% during the month and were 23.5% higher than a year earlier. They accounted for roughly 60% of the total monthly CPI increase, the BLS data showed.2
But core CPI, stripping out food and energy, rose just 0.2% on the month and 2.9% annually in May. Core commodities prices actually fell 0.1%. Food added 0.2% and shelter 0.3% — both unremarkable. The energy shock, severe by historical standards, has not yet transmitted into goods and services prices in any visible way.2
Europe is watching similar dynamics through a different lens. According to OilPrice reporting from August 26 (2026-08-26), policymakers and bond markets on the continent are more focused on natural gas than crude oil. Gas feeds directly into power generation costs, industrial processes and household energy bills in ways that oil cannot replicate with the same speed or breadth. ICE Endex TTF front-month above €70/MWh keeps that channel active even as crude retreats from its July peak.5
Oil's brief breach of $100 a barrel in late July (2026-07-25) was the moment markets appeared to price in a more damaging scenario. Rigzone reported the move came after escalating Middle East violence. The subsequent pullback provided relief: Reuters reported on July 26 (2026-07-26) that falling crude prices lifted bonds and equities as markets stepped back from their worst-case assumptions. ICE Brent front-month has since settled near $95 — still historically high, but off the threshold that forced the most urgent reassessment of rate paths.3,4
Jean Boivin, who runs the research arm of BlackRock, captured the central bank bind in blunt terms. "Central banks can always bring inflation back to 2% if they really want to, but now it would require too big of a demand crush to bear," he said. That framing — tolerating above-target headline rates while core stays contained — appears to be the operating assumption across much of the developed world.1
People familiar with the matter told Rigzone that policymakers were ready to act in September 2026 if the inflation outlook did not improve. NYMEX Henry Hub front-month was priced at $2.98/MMBtu going into that weekend, while Asian LNG benchmark JKM was recorded at $24.02/MMBtu. Neither reading points to an acute new shock, but neither signals a market fully at ease.3
The separation between headline and core CPI has carried the anchoring story this far. If Brent pushes back above $100, or if TTF surges on early winter demand or a fresh Iran escalation, cost pass-through that did not materialise in May could become harder to contain in the fourth quarter. Policymakers have said the trigger exists. Whether it gets pulled in September 2026 depends on whether the next few weeks of energy price data look more like a plateau or a new leg higher.5,3,4
