US core PCE inflation hits 3.2%, highest since late 2023, as Iran war drives energy costs

US core PCE inflation hits 3.2%, highest since late 2023, as Iran war drives energy costs March core inflation data lands a full percentage point above the Fed's target, with energy the primary driver as oil supply losses mount. The core Personal Consumption Expenditures price index rose to 3.2% in March — the highest rate since November 2023 — data published during the week of 2026-05-18 showed, putting the Fed's preferred inflation gauge a full percentage point above its 2% target with energy prices as the primary driver.² European data tells a parallel story. Germany's annual inflation rate was confirmed at 2.7% in March, the highest since January 2024, with Destatis reporting on Friday (2026-05-15) that energy prices jumped 7.2% year-on-year — the first annual increase since late 2023. Motor fuel prices rose 20% and heating oil surged 44.4%. On a monthly basis, consumer prices climbed 1.1% in March as energy costs rose 7.7%.³ The common thread in both economies is the Iran war's disruption to oil supply. A Bloomberg Intelligence survey published during the week of 2026-05-18 found a majority of market participants expecting ICE Brent crude to average $81 to $100 a barrel over the next 12 months, with demand forced to slow as it absorbs millions of barrels of supply losses.¹ The physical evidence is visible in US inventory data. Total US stocks of crude and petroleum products, including the Strategic Petroleum Reserve, fell by approximately 24.1 million barrels during the week of 2026-05-11 — one of the five largest weekly declines on record, according to EIA data.² At the same time, US exports of crude oil and petroleum products hit a new record high in the week of 2026-05-11 at 14.2 million barrels per day, 33% higher than the equivalent week in 2025.² President Trump had flagged three weeks prior that empty tankers were heading to the US; that fleet subsequently began loading and carrying cargo, which partly explains why domestic stocks fell so sharply even as export volumes surged.² ICE Brent crude front-month was trading at $85.38 as of 2026-07-16, up 0.14% on the session, while WTI front-month stood at $80.19, up 0.21%. ICE Endex TTF front-month gas added 2.47% to €54.37 as of the close on 2026-07-15, with NBP front-month moving in tandem at €56.08, up 2.38%. [LIVE_PRICES] The dollar's direction adds a layer of complexity. The DXY index was at $100.46 on 2026-07-16, down 0.34% on the session. A Fed that holds rates higher for longer tends to support the dollar, which in turn tightens financial conditions for commodity importers and can dampen industrial demand — though the near-term signal from currency markets is running in the opposite direction. [LIVE_PRICES] German producer price data offers a longer lens on how energy cost shocks feed into industrial costs. Factory gate prices have already shown how energy shortages and post-pandemic effects combine into multi-decade inflation surges, suggesting that a sustained elevation in heating oil and motor fuel prices will work its way through manufacturing costs over subsequent quarters.⁴ Consumer sentiment is already registering the strain. A Gallup poll published during the week of 2026-05-18 found 55% of Americans said their personal financial situation was getting worse — a record high in the 25-year history of the survey.² If households pull back on discretionary spending in response, demand-side pressure on global oil and gas could ease, but the sequence requires inflation to do the work that monetary policy has so far been unable to complete on its own. The next US core PCE print will show whether March's 3.2% reading was a peak or a waypoint. If it accelerates, the Fed's current stance hardens further, and the balance between supply-side losses from the Iran conflict and demand destruction from higher rates becomes the central question for crude pricing through the rest of 2026.¹
