OECD global growth forecast now points to slower output in 2026 as an energy shock lifts costs across economies. The OECD’s March 2026 interim Economic Outlook projects world GDP growth at 2.9% in 2026 and 3.0% in 2027, while G20 inflation is projected at 4.0% in 2026, up 1.2 percentage points from the prior projection.
The concrete consequence is a tougher trade-off for central banks: price pressure is rising while activity indicators are cooling. For households and firms, that mix usually shows up first as higher fuel and freight bills, then as slower hiring and tighter margins as companies try to protect cash.
What the OECD changed
The OECD linked its downgrade to disruptions in energy shipments and a jump in energy and fertiliser prices tied to the war involving Iran. Its baseline projections assume the current level of energy market disruption moderates over time, with oil, gas and fertiliser prices gradually declining from mid-2026.
The OECD also published an adverse scenario. If disruptions persist and energy prices peak higher and stay elevated longer, global growth would be 0.5 percentage points lower by the second year of the shock and inflation would be 0.9 percentage points higher.
Why the “energy shock” label matters
Energy shocks propagate through the economy through two channels at once. They raise headline inflation directly via fuel and utilities, and they raise input costs indirectly via shipping, fertiliser and petrochemical feedstocks.
Because the shock is supply-driven, cutting interest rates does not fix missing barrels or clogged logistics. High inflation also makes it harder for central banks to ease quickly if growth rolls over.
What business surveys are signaling in Europe and the US
High-frequency PMI surveys are consistent with the OECD’s warning that growth is close to stalling even as costs jump. In the euro zone, S&P Global’s March flash composite output index fell to 50.5 from 51.9, a ten-month low that its commentary said was consistent with quarterly GDP growth of just under 0.1%.
The same euro zone PMI commentary described a “record cost surge,” with input prices rising at the fastest pace since February 2023. It also said supplier delays intensified to their highest since mid-2022, pointing to renewed delivery bottlenecks rather than a simple demand slowdown.
In the United States, S&P Global’s March flash composite PMI output index fell to 51.4 from 51.9, an 11-month low driven by slower services activity. Reuters reported the survey’s prices-paid measure jumped to 63.2 and output prices rose to 58.9, with S&P Global saying the price gauges pointed to consumer inflation drifting back toward around 4%.
The US survey’s employment measure slipped to 49.7, the first contraction in 13 months, as firms reported cutting overheads amid higher costs and uncertainty. That combination is why markets start discussing “policy stuckness,” where rates stay restrictive longer than growth would normally warrant.
Importers feel the squeeze first
Net energy importers often show stress earlier in an energy shock because higher oil prices hit both inflation and external balances. India’s government flagged that dynamic in its latest monthly economic report, warning that its 7.0% to 7.4% growth outlook for the fiscal year starting April 1 faces downside risks from higher energy and freight costs.
The report said India’s current account deficit, already 1.3% of GDP in the October–December quarter, is expected to widen further in the coming fiscal year. Reuters also reported the rupee weakened to about 95 per US dollar in March amid capital outflows and higher import costs linked to the energy shock.
For policymakers, currency weakness can amplify the shock by raising the local-currency cost of fuel, fertiliser, and other imported inputs. That is one reason emerging markets can face tighter financial conditions even as growth slows.
Oil benchmark shifts are turning into a second-order macro issue
The disruption is not only pushing crude prices up, it is also distorting the way crude is priced and hedged in Asia. Reuters reported that Middle East marker Dubai spiked to an all-time high of $169.75 per barrel, surpassing Brent and making regional supply unusually expensive.
Asian refiners have begun switching to pricing some US crude purchases against ICE Brent instead of Dubai, according to Reuters sources. One consequence is market plumbing: as hedges migrate, liquidity can move with them, potentially reducing depth in Dubai-based derivatives markets during a period of high physical volatility.
Reuters also reported a sharp reversal in Dubai’s spot premium later in the week, underscoring how unstable the benchmark has become. In Japan, Reuters reported the government asked wholesalers to switch to Brent-based pricing to limit gasoline price increases, a sign that benchmark choice is becoming a consumer-price issue, not just a trader’s debate.
What to watch next
The next set of signals will come from energy logistics, inflation pass-through, and labor markets. On logistics, watch whether shipping through the Strait of Hormuz normalizes and whether supplier delivery-time indices in PMIs keep deteriorating.
On inflation, the key question is how much of the energy spike becomes embedded in broader pricing. The euro zone PMI commentary noted muted pass-through so far even as costs surge, while the US survey suggests a faster move into consumer prices.
On labor markets, the PMI employment dip is an early warning rather than a payroll report. If hiring weakens while inflation stays high, policymakers may be pushed toward a longer “hold” and more targeted fiscal relief instead of broad stimulus.
