Policymakers and market contributors constantly cite geopolitical developments as a key threat to the worldwide financial system and monetary system. However how can one quantify the potential macroeconomic results of those developments? Making use of native projections to a well-liked metric of geopolitical threat, I present that geopolitical threat weighs on GDP within the central case and will increase the severity of adversarial outcomes. This affect seems a lot bigger in rising market economies (EMEs) than superior economies (AEs). Geopolitical threat additionally pushes up inflation in each central case and adversarial outcomes, implying that macroeconomic policymakers should trade-off stabilising output versus inflation. Lastly, I present that geopolitical threat might transmit to output and inflation by way of commerce and uncertainty channels.
How has the worldwide geopolitical outlook developed?
Dangers from geopolitical tensions have grow to be of accelerating concern to policymakers and market contributors this decade.
A preferred metric to watch these dangers is the Geopolitical Threat (GPR) Index constructed by Caldara and Iacoviello (2022). The authors assemble their index utilizing automated text-search outcomes from newspaper articles. Specifically, they seek for phrases related to their definition of geopolitical threat, similar to ‘disaster’, ‘terrorism’ or ‘warfare’. Additionally they assemble GPR indices at a disaggregated country-specific stage, based mostly on joint occurrences of key phrases and particular international locations.
Chart 1 plots the evolution of the geopolitical dangers over time. Most notably, the World GPR Index (black line) spikes following the 11 September assaults. Extra lately, this index exhibits a pointy improve following Russia’s invasion of Ukraine in February 2022.
Nation-specific indices sometimes co-move considerably with the World index however might deviate when country-specific dangers come up. As an example, the UK-specific (aqua line) and France-specific indices (orange line) present extra pronounced spikes following terrorist assaults in London and Paris respectively, whereas the Germany-specific index (purple line) rises significantly strongly following the invasion of Ukraine.

The GPR index is much like the Financial Coverage Uncertainty (EPU) index, produced by Baker, Bloom and Davis. The EPU index can also be constructed based mostly on a textual content search from newspaper articles, and out there at each a worldwide and country-specific stage. But it surely measures extra generic uncertainty associated to financial policymaking, moreover uncertainty stemming from geopolitical developments.
How you can quantify the macroeconomic affect of those developments?
In mild of accelerating issues about geopolitical stress, a rising physique of literature goals to quantify the macro-financial affect of those developments. As an example, Aiyar et al (2023) study a number of transmission channels of ‘geoeconomic fragmentation’ – a policy-driven reversal of world financial integration – together with commerce, capital flows and know-how diffusion. Additionally Caldara and Iacoviello (2022) make use of a spread of empirical methods to look at how shocks to their GPR have an effect on macroeconomic variables.
These research unambiguously present that geopolitical stress has adversarial results on macroeconomic exercise and contributes to larger draw back dangers. However empirical estimates are inclined to differ considerably, relying on the character and severity of eventualities via which geopolitical tensions might play out.
My strategy focusses on the affect of geopolitical dangers on a spread of macroeconomic variables. Specifically, I take advantage of native projections (Jordà (2005)), an econometric strategy which examines how a given variable responds sooner or later to modifications in geopolitical threat as we speak. I make use of a panel knowledge set of AEs and EMEs (listed in Desk A), with quarterly knowledge from 1985 onwards.
Desk A: Checklist of economies
Notes: International locations divided into Superior and Rising Market Economies as per IMF classification. Nation-level EPU indices out there for starred economies.
Following Caldara and Iacoviello (2022), I regress a given variable on the country-level GPR index, controlling for: country-level fastened results; the worldwide GPR index; the primary lag of my variable of curiosity; and the primary lags of (four-quarter) GDP progress, shopper value inflation, oil value inflation, and modifications in central financial institution coverage charges.
I take advantage of strange least squares estimation to estimate the imply response over time of a given macroeconomic variable to geopolitical threat. However to evaluate the affect of geopolitical threat on the tail of the distribution, I comply with Lloyd et al (2021) and Garofalo et al (2023) by utilizing local-projection quantile regression. This latter strategy makes use of an outlook-at-risk framework for instance how extreme the affect of geopolitical threat may very well be underneath excessive circumstances.
How does geopolitical threat have an effect on GDP progress and inflation?
Chart 2 present the affect of geopolitical threat on common annual GDP progress throughout my panel of economies. Within the imply outcomes (aqua line), a one customary deviation improve in geopolitical dangers is anticipated to scale back GDP progress by 0.2 proportion factors (pp) at peak. However on the fifth percentile – a one-in-twenty adversarial final result – GDP progress falls by virtually 0.5pp. In different phrases, which means geopolitical threat each weighs on GDP progress but additionally will increase the severity of tail-risk outcomes, including to the worldwide threat surroundings.
The magnitude of those results is considerably smaller than Caldara and Iacoviello (2022), although they use an extended time pattern (1900 onwards), which incorporates each World Wars.

Notes: Shaded areas denote 68% confidence interval round Imply and fifth percentile estimates.
The affect of geopolitical dangers on GDP progress is heterogeneous throughout AEs and EMEs. Chart 3 plots the affect of geopolitical threat on the one-year horizon for each teams of economies, on the imply and fifth percentile. For AEs, the imply affect of geopolitical threat on GDP progress seems to be negligible, although the fifth percentile affect is extra noticeable. For EMEs, nonetheless, each the imply and fifth percentile affect of geopolitical threat are materials. This result’s in line with Aiyar et al (2023), who present that EMEs are additionally extra delicate to geoeconomic fragmentation within the medium time period.

Notes: Shaded areas denote 68% confidence interval round Imply and fifth percentile estimates.
I additionally discover that geopolitical threat tends to boost shopper value inflation, in line with Caldara et al (2024) and Pinchetti and Smith (2024). This might pose a difficult trade-off for a macroeconomic policymaker, between stabilising output versus inflation.
Chart 4 exhibits that on the imply, common annual inflation rises by 0.5pp at peak, following a geopolitical threat shock. However on the ninety fifth percentile (one-in-twenty excessive inflation final result), inflation rises by 1.4pp. As with GDP, the inflationary affect of geopolitical threat shocks seems to be bigger for EMEs, although the imply affect on AE inflation can also be statistically vital (Chart 5).

What are the potential transmission channels?
One key channel via which geopolitical threat might transmit to GDP and inflation could also be disruption to world commodity markets, significantly power. Pinchetti and Smith (2024) spotlight power provide as a key transmission channel of geopolitical threat, which pushes up on inflation. Power value shocks might even have vital results on GDP and inflation in adversarial eventualities (Garofalo et al (2023)).
The inflationary impulse following Russia’s invasion of Ukraine marks an excessive occasion of commodity market disruption (Martin and Reynolds (2023)). Sensitivity evaluation means that even excluding this era, geopolitical threat nonetheless has trade-off inducing implications for inflation and GDP.
I additionally discover that geopolitical threat results in vital disruption in world commerce, a channel additionally highlighted by Aiyar et al (2023). Chart 6 plots the estimated impacts on commerce volumes progress (measured by imports), whereas Chart 7 plots the affect on commerce value inflation (measured by export deflators). These outcomes indicate that each commerce volumes and costs are extremely delicate to world geopolitical threat. The height response of commerce volumes progress to geopolitical threat is round thrice larger than GDP, on the imply and fifth percentile. And the height response of export value inflation – representing the basket of tradeable items and companies – is considerably larger than that of shopper costs, on the imply and ninety fifth percentile.
This means that international locations are prone to be uncovered to world geopolitical threat by way of the impact on buying and selling companions: falling import volumes for Nation A implies that Nation B’s exports fall, weighing on GDP; increased export costs for County A implies that Nation B imports increased inflation from Nation A.

Notes: Shaded areas denote 68% confidence interval round Imply and fifth percentile estimates.
Chart 7: Dynamic affect of geopolitical threat on commerce value inflation
Notes: Shaded areas denote 68% confidence interval round Imply and ninety fifth percentile estimates.
Lastly, I discover that larger geopolitical threat is related to considerably larger financial uncertainty. Chart 8 exhibits the response of country-specific EPU indices (compiled by Baker, Bloom and Davis) to a rise in geopolitical threat. This means a imply cumulative improve in uncertainty of round 0.1 customary deviations; the height affect on the ninety fifth percentile is twice as nice.
This affect, whereas statistically vital, seems comparatively small in an absolute sense. For context, the US-specific EPU index rose by two customary deviations between 2017 and 2019, after the onset of the US-China commerce warfare. Nonetheless, it’s believable that uncertainty could also be a key transmission channel for geopolitical tensions within the medium time period, which can significantly weigh on enterprise funding (Manuel et al (2021)).

Conclusion
This publish presents empirical proof which quantifies the potential macroeconomic results of geopolitical developments. Geopolitical threat weighs on GDP progress, in each the central case and tail-risk eventualities, and can also be prone to increase inflation by way of a lot of channels.
Additional research might look to refine the identification of geopolitical threat shocks, to purge the underlying collection of endogenous relationships with macroeconomic variables. Additional evaluation can also be useful to substantiate why EMEs seem extra delicate to geopolitical threat than AEs, significantly transmission by way of monetary situations and capital flows. Given the heightening geopolitical tensions that policymakers have highlighted, additional analysis into the macro-financial implications of those tensions is extremely necessary at this juncture.
