There is no official "capital of the world." New York City is, however, a plausible candidate for de facto capital in several domains:
| City | Claim |
|---|---|
| London | Finance (FX, insurance), law, time zone (GMT), Commonwealth, culture |
| Geneva | UN specialized agencies (WHO, ILO, WTO), Red Cross, diplomacy |
| Brussels | EU / NATO HQ — regulatory capital of 450M |
| Washington, DC | US federal power (military, dollar, tech) — superpower capital |
| Paris | Culture, fashion, diplomacy, OECD, UNESCO |
| Singapore | Finance, trade, shipping, tech hub — Asia's connector |
| Beijing | Political capital of 1.4B, rising economic/tech gravity |
New York is a global node — perhaps the densest intersection of power, capital, culture, and people. But "capital" implies sovereignty, hierarchy, and legitimacy no city possesses. The world has no capital. It has networks — and NYC is the most connected node.
