Preliminary August data showed a renewed, energy-led inflation acceleration in both France and Spain—stronger in Spain—and reinforced the case then priced for a final 25-basis-point ECB rate increase on 10 September. The evidence points to a supply shock from the Middle East conflict rather than a broad domestic-price resurgence, but the risk was that higher energy and food costs would spread into wages and services. 415

• France: National CPI rose 2.4% year on year in August, from 2.1% in July, matching the 2.4% consensus; the harmonised HICP measure accelerated to 2.7%. The main driver was energy—especially petroleum products—with energy inflation rising to 16.7% from 12.6%; services-price pressure softened, limiting the breadth of the pickup. 571

• Spain: National CPI rose 4.3% year on year, up seven-tenths from 3.6% in July and slightly above the 4.2% market expectation. Harmonised inflation rose to 4.5%, from 3.9%; core inflation edged down to 2.9%. Fuel prices, reflecting the Iran/Middle East energy shock, were the principal reason for the headline surge. 274

• Monthly changes: The official material surfaced in the available evidence confirms the annual rates and their July changes, but does not reliably provide the precise August month-on-month figures for both the national and harmonised series. I would avoid treating an unsourced monthly number as definitive; the releases are explicitly flash estimates. 52

• Euro-area context: Eurozone annual inflation had already risen to 2.9% in July, above the ECB’s 2% objective, as energy prices increased. The France and Spain releases indicated that the pressure was continuing into August, with Spain’s 2026 path particularly sharp—from 3.6% in July to 4.3% in August on the national measure. 106

• ECB implication: The figures strengthened the prevailing expectation of a 25-basis-point ECB increase on 10 September, followed by a prolonged hold. The concern was not simply one month of oil-driven headline inflation, but possible second-round effects: energy and fuel costs feeding into food, wages and then services, making inflation more entrenched. The ECB had already identified the Middle East war as inflationary, while noting energy-price volatility and unusually high uncertainty. 1545

• Growth trade-off: Higher oil prices squeeze real incomes and firms’ costs, while drought, heatwaves and wildfires threaten agricultural supply, food prices, supply chains and output. One estimate cited heat-related disruption as potentially cutting EU GDP by about 1%, though that is an external estimate rather than an ECB forecast. 98

• U.S. and FX-market view: The “Fed likely to hold” characterization became outdated by late August: earlier reporting said traders expected a September hold after softer inflation, but subsequent data and Chair Warsh’s remarks lifted the market-implied chance of a September Fed hike to about 60%. Thus, any expected year-end easing path had become materially less certain and more conditional on inflation data. 816

• EUR/USD: The available sources do not provide a verified contemporaneous EUR/USD level or a precise year-end U.S. rate-path pricing. Insufficient evidence to state either number reliably. Directionally, a more hawkish ECB can support the euro, but a simultaneous repricing toward a more hawkish Fed supports the dollar; the exchange-rate outcome therefore depended on which tightening repricing dominated.
