In the present day, we’re happy to current a visitor contribution by Laurent Ferrara (Professor of Economics at Skema Enterprise College, Paris and Chair of the French Enterprise Cycle Courting Committee), and Jamel Saadaoui (Professor at College of Paris 8 – LED).
After years of rising inflation within the wake of the post-Covid restoration and the struggle in Ukraine, disinflationary pressures are actually seen throughout all superior economies. In some international locations, inflation has even fallen effectively under central financial institution targets. That is the case for France, the place the newest figures point out that shopper costs rose by solely 0.9% year-on-year in November 2025 (supply : INSEE). Forecasts additionally level to persistently low inflation over the following two years—1.3% in 2026 and 1.8% in 2027, following 1% in 2025—in keeping with the newest Banque de France forecasts.
When assessing the stability of dangers surrounding this baseline state of affairs, geopolitical dangers have to be taken critically, given the present local weather of world tensions, significantly in Europe. Current tutorial literature has begun to doc the dynamic results of geopolitical tensions on inflation, though their signal is theoretically ambiguous. On the one hand, weaker demand -through decrease financial progress and declining shopper sentiment – tends to depress shopper costs. Then again, geopolitical shocks increase commodity costs and set off foreign money depreciation, each of which push inflation upward. Oil costs, particularly, reply to fears of provide disruptions (see Mignon and Saadaoui) .
Past imported inflation, fiscal dynamics are additionally more likely to reinforce inflationary pressures. Rising protection spending, rising public debt, and tighter monetary situations mix to exacerbate fiscal imbalances and monetary stress, possible including to the general inflationary setting.
Caldara et al. have not too long ago proposed to estimate the consequences of the Geopolitical Danger index (GPR index developed by Caldara and Iacovello) on inflation across the globe. Utilizing a month-to-month world SVAR spanning a number of a long time, they present that heightened geopolitical tensions systematically improve commodity costs. Additionally they show that this “commodity channel” contributes to increased inflation regardless of simultaneous deflationary forces stemming from weaker output, decrease shopper sentiment, decreased commerce, and tighter monetary situations. We partly evaluate this literature in a current work that we did, forthcoming within the Revue d’Economie Financière (see slides right here).
What can we receive when estimating the consequences of a geopolitical shock on French inflation? Past the well-known GPR index, a number of different geopolitical indicators have not too long ago been developed within the analysis literature. A very attention-grabbing contribution is supplied by Bondarenko et al., who concentrate on European international locations. Noting that the GPR index depends totally on U.S.-centric newspapers, they suggest a text-mining strategy primarily based on native newspapers from 5 main euro space economies—Germany, France, Italy, Spain, and the Netherlands—to assemble country-specific measures of geopolitical threat.
Let’s base our empirical evaluation on the index of Bondarenko for France (see Determine 1).

We’re going to estimate a structural geopolitical shock and to take a look at its dynamic impact on inflation utilizing a Native Projection strategy. The structural geopolitical shock is recovered utilizing a Choleski identification in SVAR mannequin, that additionally controls for GDP progress and modifications in oil costs (Brent). We estimate the mannequin on the quarterly frequency. The structural geopolitical shock stemming from this strategy is offered Determine 2.

Based mostly on this estimated geopolitical shock, IRFs might be computed utilizing the Native Projection methodology. The IRF of inflation to a one standard-deviation shock (about 1.5) is offered in Determine 3. The utmost influence of about 0.25pp is reached after 2 years (8 quarters). Apparently, there aren’t any clear important results in the course of the first yr after the shock. A potential clarification is that damaging demand results are counter-balanced by rising imported inflation.

In coverage phrases, the longer term evolution of shopper costs will rely on the amplitude of a potential structural shock estimated by the geopolitical index from Bondarenko et al. Let’s assume that the amplitude is as giant because the one noticed in the course of the struggle in Iraq, that may be a worth of 5.5 in 2003q1 (see Determine 2), representing about 3.7 instances the usual deviation of the shock. Such a geopolitical occasion would possible generate a surplus of inflation of about 3.7*0.25=0.93pp after 8 quarters. If we translate the quarterly profile into annual figures, this is able to shift upward inflation in 2027 to about 2.5%, including thus inflationary pressures to the baseline state of affairs for France (1.8% in 2027 in keeping with Banque de France).
