Inflationary pressures in Europe have intensified significantly, driven by ongoing turmoil in the Middle East impacting global energy markets. Consumer price growth in France and Spain accelerated to its highest levels in nearly two years during May, solidifying market expectations that the European Central Bank (ECB) will soon restart its interest rate hiking cycle.

Data shows France's Consumer Price Index (CPI) rose 2.8% year-on-year in May, slightly below the market forecast of 2.9% but still marking the highest rate in nearly two years. Spain's CPI increased by 3.6% year-on-year, matching expectations and also reaching a new high for 2024. Soaring energy prices, particularly for natural gas and fuel, remain the primary driver of rising costs.

Analysts note that sustained tensions in the Middle East following military actions three months ago have fueled supply concerns for crude oil and natural gas, leading to sharp increases in European energy prices. The eurozone economy is increasingly at risk of sliding into a stagflationary scenario characterized by high inflation and weak growth.

**ECB Shifts Hawkish: June Rate Hike a Near-Certainty**

The inflation figures from France and Spain kick off a series of price reports from major eurozone economies. Markets are closely watching upcoming data from Germany and Italy. Economists anticipate Germany's May inflation rate may dip slightly but remain around 3%, while Italy's rate could climb further. The eurozone's overall inflation data for May, due next week, is also expected to exceed April's 3%, indicating the ECB is moving further away from its 2% inflation target.

Recently, hawkish voices within the ECB have grown louder. From Executive Board member Isabel Schnabel to Chief Economist Philip Lane, long considered a dove, several policymakers have hinted that the ECB may need to raise rates for the first time since 2023. Minutes from the ECB's April meeting revealed that while policymakers chose to hold rates steady, concerns were mounting about energy shocks triggering "second-round inflation effects." The minutes stated that a "look-through" approach was becoming increasingly untenable, with some officials shifting the debate from *whether* to hike to *when* would be most appropriate.

Financial markets are now almost universally expecting the ECB to raise its deposit rate from the current 2% to 2.25% at its June 11 policy meeting. Swap market data implies a roughly 90% probability of a 25-basis-point hike in June, with expectations for an additional hike by year-end also widely priced in. Analysis from institutions like Societe Generale suggests markets have fully priced in two rate hikes within 2026, with about a 50% chance of a third move.

**Energy Shock Spreading to Core Inflation**

The accelerating inflation in France and Spain is not an isolated trend. According to final estimates from Eurostat, the eurozone's annual inflation rate for March 2026 was revised up to 2.6%, the highest since July 2024. Inflation climbed further to 3% in April, with energy prices again the main driver. April rates for France, Germany, Italy, and Spain were 2.5%, 2.9%, 2.8%, and 3.5%, respectively, all reflecting the strong pass-through of the energy shock across the bloc.

OECD data shows energy inflation in France and Germany has surpassed 7%, with the full impact on consumer prices yet to peak. The surge is linked to global markets; since the outbreak of military conflict in late February 2026, crude oil prices have nearly doubled from around $60 per barrel to near $120. Unresolved issues regarding the Strait of Hormuz have led to volatile swings in oil prices. Brent crude futures recently experienced sharp fluctuations, trading at $97.29 per barrel as of May 28 with weekly volatility well above historical averages.

The transmission of energy prices to consumers is accelerating. In Spain, tax relief measures introduced to combat the energy crisis are set to expire on May 31, 2026, reverting VAT on electricity, gas, and related products to the standard 21% rate and reinstating a special electricity tax of 5%. While some support for vulnerable groups will continue, the withdrawal of tax benefits adds an extra burden on top of already high energy prices.

Analysts note that prolonged high energy prices due to Middle East conflict are persistently pushing Europe's inflation baseline higher via energy cost channels. The ECB's primary concern is not energy prices themselves, but their spillover into the broader economy. There are growing signs of "second-round effects," with rising business costs in transport, manufacturing, and services being increasingly passed on to consumers. Internal ECB documents indicate market inflation expectations for 2026 and 2027 have been significantly revised upward.

A recent ECB blog post noted that the war could elevate medium-term inflation expectations among eurozone consumers, creating a "double trauma" effect following the 2022 price surge. Policymakers are particularly focused on preventing war-induced energy cost spikes from spreading into broader inflation via wage and pricing mechanisms. The post warned of risks that medium-term expectations could be adjusted further upward.

ECB economic projections suggest eurozone inflation could rise above 3.5% this year if Middle East conflicts persist, potentially nearing 5% in extreme scenarios.

**Europe Faces Stagflation Challenge**

Simultaneously, European economic growth is slowing. Revised data shows French GDP contracted 0.1% quarter-on-quarter in Q1 2026, worse than the initial "zero growth" estimate, with consumer confidence at a three-year low. The eurozone's overall growth outlook has also dimmed, with 2026 GDP growth forecasts slashed to 0.9% from 1.4% in 2025. ECB minutes show Q1 GDP growth slowed to just 0.1%, half the rate of Q4 2025. Germany's prolonged manufacturing slump and declining export competitiveness contrast with Spain, forecast to be the "growth champion" among the four largest economies with 2.2% GDP growth.

The ECB faces a complex dilemma: persistently high energy prices compel tighter monetary policy, but rate hikes could further stifle already weak growth. Europe's heavy reliance on energy imports, particularly from the Middle East, makes it one of the most vulnerable economies to global energy shocks. Concerns are mounting that Europe could be entering a 1970s-style stagflation phase.

The ECB has stated its future policy path will depend heavily on energy market developments and whether inflation expectations become unanchored. Energy shocks are not only raising living costs but also eroding European industrial competitiveness. The ECB's semi-annual financial stability report warns that high energy prices will drag on growth, reducing expected tax revenues for 2026 government budgets, while increased fiscal support for households and firms could widen deficits and pressure bond prices.

Analysis suggests the EU's oil and gas import bill has swelled by an additional approximately €60 billion since the conflict began, a figure that continues to grow rapidly. If oil prices remain elevated and businesses and consumers begin to form persistent price increase expectations, the ECB may be forced into more aggressive tightening than markets currently anticipate.

For global markets, this signals Europe may be re-entering a "high-interest-rate era." Beyond the global AI boom, energy and geopolitical risks are re-emerging as core variables shaping global financial markets.
