Contrasting October data
Inflation in the eurozone and Switzerland had contrasting profiles in October. In the eurozone, the annual inflation rate rose from 1.7% year-on-year (YoY) in September to 2.0% YoY in October, exceeding market expectations of 1.9%. In contrast, inflation in Switzerland fell from 0.8% YoY to 0.6% YoY against expectations of a stabilisation of inflation at the previous month’s level.
Central bank next steps?
Interestingly, markets responded by increasing the implied probability of a more expansionary monetary policy stance over the coming quarters in both economies. The common feature of the data releases is that both point to inflation being significantly lower than the most recent forecasts published by the ECB and SNB.
In the case of the ECB, the macroeconomic projections published in September predicted inflation averaging 2.6% YoY in 2024Q4. The October data suggests that even considering a marked adverse base effect linked to energy prices in the final two months of the year, inflation will not exceed 2.3% YoY on average in this quarter.
In Switzerland, the SNB's conditional inflation forecasts published in September saw an average inflation rate of 1% in 2024Q4. However, October’s data point to quarterly average inflation of around 0.7%, again anticipating a slight rebound in inflation linked to fuel prices.
Inflation projections
Markets therefore seem to be focusing on the divergence between the realised inflation rate and the central banks' short-term forecasts. Indeed, since the beginning of 2023 a relationship has emerged between the one-quarter ahead inflation forecast error of the ECB and the SNB and their subsequent decisions on interest rates (see Chart 1 a and b).
