gdp — by either nominal or ppp measure (see nominal vs ppp gdp) — is a surprisingly bad proxy for geopolitical power. once internalized, a lot of "which country is more powerful" headlines start looking dumb.
the framework
power ≠ gdp
power = (sectoral chokepoints) × (state willingness to use them) × (ability to project force) × (alliance network)
gdp is the fuel tank. it tells you potential energy. it doesn't tell you what engine the country built around it, or whether they'll step on the gas.
three things gdp misses
1. composition over totals
a service-heavy economy and a manufacturing-heavy economy of the same gdp are wildly different in a crisis. services don't build artillery shells, ships, or drones.
mechanism
the us discovered this in 2022 trying to surge ammunition production for ukraine — found it would take years to scale because the industrial base had been hollowed out for decades. china can currently outproduce the us on shells by ~10:1. doesn't show up in gdp.
2. sectoral chokepoints
the number that actually matters geopolitically isn't "gdp" — it's "what fraction of [critical thing] does a country control?"
| sector | dominant country | share |
|---|---|---|
| rare earth processing | china | ~85% |
| solar panels | china | ~80% |
| ev batteries | china | ~75% |
| active pharmaceutical ingredients | china | ~40% (us ~10%) |
| shipbuilding capacity | china / south korea | ~50% / ~30% (us ~0.1%) |
| leading-edge semiconductors | taiwan (tsmc) | ~90% |
| semiconductor lithography (upstream) | netherlands (asml) | single point of failure |
each one is a knife at someone's throat. the us has a few too — high-end chips, dollar/swift, jet engines, gps — but the 20-year trend has been one direction.
3. state capacity ≠ gdp
russia's nominal gdp is smaller than italy's. italy hasn't fought a war in 80 years. russia has sustained a major continental land war for 3+ years against a western-backed adversary, absorbing 500k+ casualties, and recovering territory.
gdp wildly undersells the coercive capacity of an authoritarian state willing to mobilize. same logic for why iran punches 10x its gdp weight, and why germany's massive economy translates to almost no geopolitical influence.
applying the framework
| country | fuel tank | engine | will | alliances |
|---|---|---|---|---|
| us | big | mediocre (manufacturing hollowed, political dysfunction) | uses financial chokepoints | strong |
| china | big | enormous on manufacturing/sectoral side | increasingly willing | weak |
| russia | small | brutal | total | none |
| germany | big | none | none | strong (but passive) |
| iran | small | resourceful | high | regional proxy network |
brics+ vs g7
by ppp, the brics+ bloc (brazil, russia, india, china, plus recent additions — iran, uae, egypt, ethiopia) now exceeds the g7 in total economic output. this threshold was crossed in 2024.
the narrative shift in the global south — countries hedging between blocs, dedollarization talk, brics payment systems — is partly downstream of this statistical fact getting noticed.
open follow-ups
- reserve currency — why the us dollar's reserve status is the single most underrated source of us power, and the conditions under which it could end
- china demographic cliff — why china's ppp lead may plateau and reverse (demographics, middle-income trap, debt overhang)
- taiwan semiconductor question — why everyone's geopolitical strategy basically reduces to "who controls tsmc"
- india trajectory — under-hyped or over-hyped?
