Policymakers and market members persistently 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 preferred 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 impression 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 through commerce and uncertainty channels.
How has the worldwide geopolitical outlook advanced?
Dangers from geopolitical tensions have turn into of accelerating concern to policymakers and market members 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. Particularly, they seek for phrases related to their definition of geopolitical threat, akin to ‘disaster’, ‘terrorism’ or ‘struggle’. In addition they assemble GPR indices at a disaggregated country-specific stage, based mostly on joint occurrences of key phrases and particular nations.
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 reveals a pointy enhance 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 notably strongly following the invasion of Ukraine.

The GPR index is just 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 accessible at each a worldwide and country-specific stage. But it surely measures extra generic uncertainty associated to financial policymaking, apart from uncertainty stemming from geopolitical developments.
Tips on how to quantify the macroeconomic impression of those developments?
In gentle of accelerating considerations about geopolitical stress, a rising physique of literature goals to quantify the macro-financial impression of those developments. As an example, Aiyar et al (2023) look at a number of transmission channels of ‘geoeconomic fragmentation’ – a policy-driven reversal of worldwide financial integration – together with commerce, capital flows and expertise diffusion. Additionally Caldara and Iacoviello (2022) make use of a variety 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 likely to differ considerably, relying on the character and severity of situations by which geopolitical tensions might play out.
My method focusses on the impression of geopolitical dangers on a variety of macroeconomic variables. Particularly, I take advantage of native projections (Jordà (2005)), an econometric method which examines how a given variable responds sooner or later to modifications in geopolitical threat in the present day. I make use of a panel knowledge set of AEs and EMEs (listed in Desk A), with quarterly knowledge from 1985 onwards.
Desk A: Listing of economies
Notes: International locations divided into Superior and Rising Market Economies as per IMF classification. Nation-level EPU indices accessible for starred economies.
Following Caldara and Iacoviello (2022), I regress a given variable on the country-level GPR index, controlling for: country-level mounted results; the worldwide GPR index; the primary lag of my variable of curiosity; and the primary lags of (four-quarter) GDP development, client worth inflation, oil worth inflation, and modifications in central financial institution coverage charges.
I take advantage of abnormal least squares estimation to estimate the imply response over time of a given macroeconomic variable to geopolitical threat. However to evaluate the impression of geopolitical threat on the tail of the distribution, I observe Lloyd et al (2021) and Garofalo et al (2023) through the use of local-projection quantile regression. This latter method makes use of an outlook-at-risk framework for instance how extreme the impression of geopolitical threat might be below excessive circumstances.
How does geopolitical threat have an effect on GDP development and inflation?
Chart 2 present the impression of geopolitical threat on common annual GDP development throughout my panel of economies. Within the imply outcomes (aqua line), a one normal deviation enhance in geopolitical dangers is anticipated to scale back GDP development by 0.2 proportion factors (pp) at peak. However on the fifth percentile – a one-in-twenty adversarial final result – GDP development falls by nearly 0.5pp. In different phrases, which means that geopolitical threat each weighs on GDP development but additionally will increase the severity of tail-risk outcomes, including to the worldwide threat setting.
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 impression of geopolitical dangers on GDP development is heterogeneous throughout AEs and EMEs. Chart 3 plots the impression of geopolitical threat on the one-year horizon for each teams of economies, on the imply and fifth percentile. For AEs, the imply impression of geopolitical threat on GDP development seems to be negligible, although the fifth percentile impression is extra noticeable. For EMEs, nonetheless, each the imply and fifth percentile impression of geopolitical threat are materials. This result’s according to 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 lift client worth inflation, according to 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 reveals 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 impression of geopolitical threat shocks seems to be bigger for EMEs, although the imply impression on AE inflation can also be statistically important (Chart 5).

What are the potential transmission channels?
One key channel by which geopolitical threat may transmit to GDP and inflation could also be disruption to international commodity markets, notably vitality. Pinchetti and Smith (2024) spotlight vitality provide as a key transmission channel of geopolitical threat, which pushes up on inflation. Power worth shocks may even have important results on GDP and inflation in adversarial situations (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 important disruption in world commerce, a channel additionally highlighted by Aiyar et al (2023). Chart 6 plots the estimated impacts on commerce volumes development (measured by imports), whereas Chart 7 plots the impression on commerce worth inflation (measured by export deflators). These outcomes suggest that each commerce volumes and costs are extremely delicate to international geopolitical threat. The height response of commerce volumes development to geopolitical threat is round 3 times larger than GDP, on the imply and fifth percentile. And the height response of export worth inflation – representing the basket of tradeable items and providers – is considerably larger than that of client costs, on the imply and ninety fifth percentile.
This suggests that nations are more likely to be uncovered to international geopolitical threat through the impact on buying and selling companions: falling import volumes for Nation A implies that Nation B’s exports fall, weighing on GDP; larger export costs for County A implies that Nation B imports larger inflation from Nation A.

Notes: Shaded areas denote 68% confidence interval round Imply and fifth percentile estimates.
Chart 7: Dynamic impression of geopolitical threat on commerce worth 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 reveals the response of country-specific EPU indices (compiled by Baker, Bloom and Davis) to a rise in geopolitical threat. This suggests a imply cumulative enhance in uncertainty of round 0.1 normal deviations; the height impression on the ninety fifth percentile is twice as nice.
This impression, whereas statistically important, seems comparatively small in an absolute sense. For context, the US-specific EPU index rose by two normal deviations between 2017 and 2019, after the onset of the US-China commerce struggle. Nonetheless, it’s believable that uncertainty could also be a key transmission channel for geopolitical tensions within the medium time period, which can notably weigh on enterprise funding (Manuel et al (2021)).

Conclusion
This put up presents empirical proof which quantifies the potential macroeconomic results of geopolitical developments. Geopolitical threat weighs on GDP development, in each the central case and tail-risk situations, and can also be more likely to elevate inflation through a variety of channels.
Additional research might look to refine the identification of geopolitical threat shocks, to purge the underlying sequence of endogenous relationships with macroeconomic variables. Additional evaluation may additionally be useful to substantiate why EMEs seem extra delicate to geopolitical threat than AEs, notably transmission through monetary circumstances 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.
