Commodity Rally Since August Tightens the Inflation Bind for ECB
European gas up 34% and a broad commodity surge since August are making it harder for central banks to treat supply-side price shocks as temporary.
The Bloomberg Commodity Index has climbed to multi-year highs on a rally that, since the start of August, pushed European gas prices up 34% and gasoline up 22%, while zinc, copper, silver, platinum, gold, sugar and cocoa all moved sharply higher in the same period, according to analysis published Wednesday (2026-09-09) by Oilprice.com. Former Goldman Sachs commodities head Jeff Currie warned this summer of growing scarcity in the physical economy, a concern the index move is now reflecting.7
That breadth complicates any single-market explanation. When only crude oil moves, central bankers can wait for demand destruction to do the work. When energy, metals and agricultural commodities rally in lockstep over six weeks, dismissing the price pressure as supply-side and transient demands more evidence than markets are currently supplying.7
ICE Brent front-month was trading at $100.78 a barrel as of 07:10 UTC Thursday (2026-09-10). The path to that level was violent. When the Strait of Hormuz effectively closed on March 4, Brent surged more than 55% from pre-war levels near $72 a barrel, rocketing to highs between $119 and $120 before retreating into a lower range, according to Rigzone. Six months of conflict have not brought prices back to where they started.3
The case for short-lived inflation found support on Bloomberg Surveillance, where one analyst argued that because oil can still flow out of the region, meaningful inflation from energy prices is unlikely for the foreseeable future. The logic is that supply shocks that slow demand tend to cap their own inflationary effect over time.5
But supply remains constrained. Diamondback Energy argued in August that even if hostilities eased, producers would need to rebuild depleted stockpiles before supply caught up with demand — a process that sustains upward price pressure for months rather than weeks. Saudi Aramco had warned earlier that unless shipping disruptions ended quickly, the consequences would prove lasting.6
A Bloomberg Intelligence survey put the central expectation for supply disruptions at 3 million to 7 million barrels a day, with few respondents projecting outages above 10 million. Most survey participants expected ICE Brent front-month to average $81 to $100 over the next 12 months, implying a prolonged elevated range rather than a return to pre-war norms. About a quarter of respondents anticipated an increase in hedging and risk-management activity, compared with 15% who saw more opportunistic risk-taking — a posture more consistent with managing duration than betting on a quick reversal.1
In Europe, where imported energy costs hit government balance sheets directly, the policy response has shifted. The European Commission is considering a plan allowing member states to spend 0.3% of GDP on energy-related measures outside the EU's fiscal framework, a concession that signals governments are no longer treating the shock as brief. The Commission's spring 2026 forecast stated that in response to higher inflation, the ECB and most other EU central banks are expected to tighten monetary policy or, at minimum, delay rate cuts.2
ICE Endex TTF front-month jumped 4.56% in Wednesday's (2026-09-09) European session to €79.29/MWh. German Power front-month gained 4.74% to €161.82/MWh in the same session, while THE M+1 rose 4.46% to €80.48/MWh. Analysts covering the conflict expect it to add roughly 0.8% to global inflation; if sustained military action further impairs tanker flows through the Strait of Hormuz, prices could push well above $100 and hold there, according to Rigzone.3,7
On the supply side, the US Energy Information Administration projects American crude output reaching a record 14.1 million barrels a day in 2027, which would eventually provide meaningful cushion. That is a 2027 story, not a 2026 one.1
People familiar with ECB deliberations told Bloomberg that rate-setters were prepared to act in September if the inflation outlook failed to improve. European gas has risen 34% since August, German Power closed near €162/MWh Wednesday (2026-09-09), and the Bloomberg Commodity Index sits at multi-year highs. A 0.25 percentage-point move would signal determination. It would not add a barrel of oil.2,4
