Eco Notepad features educational articles that present the research, studies and economic expertise of the Banque de France. The blog is aimed at students, professionals, journalists and academics. Some articles will be devoted to analyses carried out by the Bank's branch network, on specific topics. The opinions expressed are those of the authors and do not necessarily reflect the position of the Banque de France, the Eurosystem, or the institutions employing these authors.
Eco Notepad editors asks authors submitting a post to the blog to confirm that they have no conflicts of interest. If one of the authors of a blog benefits of an external financing, he should state the sources of financial support for the particular research it describes.

According to Milton Friedman, economics Nobel prize winner, “inflation is always and everywhere a monetary phenomenon”. This blog examines the French assignat debacle and hyperinflation (1795-96) and suggests that unsustainable public finances and fiscal dominance were the primary causes of an excessive increase in the money supply and hyperinflation.
According to the Banque de France's projection, French inflation measured by the Harmonised Index of Consumer Prices (HICP) will gradually return towards 2% in 2025. How is this projection produced? This post describes our main tools and shows how, by combining modelling and expert judgement, we produce disaggregated inflation forecasts that are consistent with the overall macroeconomic scenario.

The impact of higher inflation varies across insurance categories. Insurers are facing an erosion in the value of non-inflation indexed assets and of their real returns, some of which is associated with an increase in liabilities . However, they have different levers at their disposal to adapt to this environment and meet their commitments towards policyholders.

This post investigates how monetary policy announcements in the US and the euro area have affected inflation expectations since 2021. We show that a 100bp surprise increase in 2-year rates translated into a 30-50bp drop in medium-term inflation expectations. Central banks’ effective communication was the main factor influencing inflation expectations around these announcements.

The recent rise in inflation could affect households' and businesses' perception of inflation. This post describes new indicators of perceived inflation in France constructed from alternative data: newspaper articles and messages from the social network Twitter. The advantage of such data is that they are available at high frequency and in real time.

The increase in global wheat prices in the last two years, especially after the start of the Ukraine war, reflects a strong market integration and a high dependence on energy and fertiliser prices. As several developing countries depend on a small number of wheat exporters, curbing food insecurity will require coordinated action and crop diversification.

The rise in world commodity prices since mid-2020 has fuelled inflation in Africa. A new estimation strategy shows a pass-through of about 30% from commodity prices to consumer prices on the continent, which is higher than existing estimates. The impact is greater in low-income countries and in those countries where the food share in the consumption basket is the largest.

Monetary policy consists in part in managing inflation expectations of different agents. New US evidence on heterogeneous frequency of forecast revisions and disagreement among various categories of agents (households, firms, professional forecasters) suggests that targeting communication to specific groups could be a useful tool for central bankers.

For the first time, the Banque de France is publishing the results of a survey on business leaders’ inflation expectations, collected since the end of 2021. One-year inflation expectations have increased since the beginning of the year and their median stands at 5% in the second quarter of 2022. Longer-term expectations (3-5 years) are also rising, but more slowly, with a median of 3%. This survey was conducted prior to the ECB's monetary policy normalisation announced on 9 June, which is expected to contribute to the gradual "re-anchoring" of inflation expectations.

This blog post examines to what extent the recent surge in international transport costs has fuelled US import price inflation. While we find a moderate effect at the aggregate level, there are significant differences across products that are largely driven by the degree of containerisation.
