Under the impact of the Middle East war, the European Central Bank raises interest rates by 25 basis points: a difficult balance between inflation targets and weak growth.

From War to Inflation: The ECB's Policy Crossroads

On June 11, 2026, the European Central Bank's Governing Council announced a 25-basis-point increase in all three key interest rates, raising the deposit facility rate from 2.00% to 2.25%, the main refinancing operations rate from 2.15% to 2.40%, and the marginal lending facility rate from 2.40% to 2.65%. This is the first rate hike by the European Central Bank since the outbreak of the Middle East war that explicitly targets the inflationary pressures triggered by the energy shock as its core objective.

In the early part of the year, when easing expectations had dominated the market, this decision stood out as especially striking. However, the continued escalation of the war has changed the short-term path of inflation and forced a recalibration of monetary policy. The European Central Bank clearly stated in its statement that the Middle East war is generating inflationary pressures, and that this rate hike decision is robust across a variety of scenarios—which precisely reveals the extreme uncertainty facing policymakers.

Inflation Forecasts Revised Up: The Transmission Chain of the Energy Shock

According to the new baseline projections of Eurosystem staff, headline inflation in the euro area is expected to average 3.0% in 2026, 2.3% in 2027, and fall back to 2.0% in 2028. Compared with the March projections, the inflation path for 2026 and 2027 has been significantly revised upward, with the key driver being higher energy prices, which are expected to pass through to food, goods, and services prices to some extent.

The core inflation forecast excluding energy and food is more telling: it is projected to remain at 2.5% in both 2026 and 2027, only declining to 2.2% in 2028. This implies that even as the energy shock gradually fades, underlying price pressures remain sticky, possibly stemming from wage growth, corporate pricing behavior, and supply chain restructuring. The ECB's previously set 2% medium-term target appears to require a longer period to achieve.

The upward revision to inflation forecasts reflects the war's profound impact on energy markets. The Middle East is a critical node in global oil and gas supply. The conflict has not only directly pushed up crude oil and natural gas prices but also triggered knock-on effects on shipping insurance, logistics routes, and long-term contract pricing. For the euro area, which depends on energy imports, imported inflationary pressures further erode real incomes through a deterioration in the terms of trade, creating a negative feedback loop on the demand side.

Growth Forecasts Revised Down: The Shadow of Stagflation Looms

In stark contrast to the upward revision in inflation, economic growth forecasts have been lowered. The latest baseline projections show euro area real GDP growth averaging only 0.8% in 2026, 1.2% in 2027, and 1.5% in 2028. Compared with the March projections, growth expectations for 2026 and 2027 have been revised downward. The European Central Bank attributes this to the more pronounced impact of the war on commodity markets, real incomes, and confidence.This combination—rising inflation, falling growth—is the classic face of stagflation. Although the euro area is unlikely to fall into a severe recession, a growth rate of 0.8% almost implies stagnation in per capita output. Manufacturing is under the twin pressures of higher energy costs and weak external demand, while the services sector, though more resilient, has seen confidence indicators begin to soften.

Moreover, uncertainty from the war could weigh on investment. Faced with energy price volatility and geopolitical risks, businesses tend to postpone capital expenditure, further undermining medium-term growth potential. The European Central Bank stressed in its statement that the full impact of the war on medium-term inflation and growth will depend on the intensity and duration of the energy price shock, as well as the scale of its indirect and second-round effects.

The Logic of Rate Hikes: Staying the Course Amid Uncertainty

Why would the European Central Bank still choose to raise rates when growth is so weak? The core lies in its price stability mandate. The Governing Council reiterated its commitment to ensuring inflation returns to the 2% target over the medium term. Current inflation expectations are above this level and face upside risks, making appropriate monetary policy tightening necessary.

The ECB specifically noted that "the decision is robust across a range of scenarios." This statement deserves careful thought. It means policymakers are not relying on a single baseline forecast, but have conducted stress tests, evaluating the outcomes of raising rates versus not raising them under different paths of the war's evolution. In a scenario where the Middle East situation could escalate and energy prices could surge further, raising rates in advance helps anchor inflation expectations and prevent second-round effects from getting out of control.

However, such robustness does not come without costs. Rate hikes further suppress aggregate demand and may exacerbate the downside to growth. The ECB is clearly aware of this trade-off and has therefore retained ample flexibility: the statement reiterates a data-dependent, meeting-by-meeting approach, with no pre-commitment to a particular rate path. This suggests that if inflation falls rapidly or growth deteriorates sharply, the ECB could equally pause or reverse rate hikes.

Balance Sheet Shrinkage and Transmission Protection

Beyond the interest rate tool, the ECB is also continuing to normalize its balance sheet. The combined size of the Asset Purchase Programme (APP) and the Pandemic Emergency Purchase Programme (PEPP) is declining at a measurable and predictable pace, as the Eurosystem no longer reinvests the principal of maturing securities. This effectively tightens financial conditions further, on top of interest rates.

Notably, the ECB again emphasized the availability of the Transmission Protection Instrument (TPI). The TPI is designed to counter unwarranted, disorderly market dynamics that could pose a serious threat to the transmission of monetary policy across all euro area countries. During a rate-hiking cycle, spreads between peripheral and core countries within the euro area often face widening pressure, and the risk of financial fragmentation rises accordingly. The TPI acts as a safety net, allowing the ECB to fend off fragmentation risks without compromising its overall monetary policy stance.

Risk Structure and Outlook: A Game of Waiting for DataThe European Central Bank's assessment of the outlook is clearly tilted toward caution: inflation risks are tilted to the upside, while growth risks are to the downside. This asymmetric risk structure implies that any future policy adjustments will be highly dependent on incoming data, especially energy prices, wage negotiations, core inflation trends, and the transmission effects of credit conditions.

For market participants, the signal conveyed by this rate hike is not merely the direction of tightening, but also the management of uncertainty. The ECB's path is no longer linearly predictable; rather, it is distributed across a wide range of outcomes. Interest rates could rise further within the year, or the central bank could shift to a wait-and-see stance if economic growth deteriorates markedly.

From a broader macro perspective, the ECB's decision reflects a common challenge facing the global economy: how geopolitical shocks interact with monetary policy inertia. The Middle East war is not merely a regional conflict; through energy markets, trade channels, and confidence effects, it is reshaping the global balance between inflation and growth. The ECB's choice to raise rates is a clear signal that it places the inflation target above short-term growth. But the ultimate success or failure of this choice depends on the trajectory of the war and whether the global economy can withstand the test of higher interest rates.

In 2026, a year fraught with uncertainty, the era of accommodative monetary policy seems to be rapidly fading, replaced by a more cautious, more data-dependent policy paradigm. The ECB's decision today is merely the latest footnote to this paradigm shift.
