ECB Prepares Quarter-Point Rate Hike Despite Uncertainty Over Inflation Drivers

The European Central Bank (ECB) is widely expected to raise interest rates by a quarter point on Thursday, taking its deposit rate from 2.25% to 2.5%. However, the reasoning behind this move and its implications are less certain.

The ECB's decision comes after August's inflation release showed eurozone inflation at 3.3%, up from 2.9% in July. While this might seem like a cause for concern, core inflation - which excludes energy, food, alcohol, and tobacco - actually declined to 2.4% from 2.5%. Services inflation, closely linked to wages and domestic demand, also fell to 3% from 3.3%.

According to the ECB's own analysis, roughly 90% of the rise in energy inflation between January and May was due to adverse energy supply factors stemming from geopolitical tensions. This suggests that the current inflation issue is primarily a supply-side problem rather than a demand-driven one.

The divergence across EU member states highlights the uneven nature of the situation. August inflation stood at 4.5% in Spain, 2.9% in Germany, and 2.7% in France - three economies confronting the same energy shock with markedly different outcomes.
