Change the ruler, change the champion: nominal vs PPP

Measure at market exchange rates and Luxembourg wins; measure what money actually buys locally (PPP) and Singapore takes the crown at ~$157K.

The top 3

  1. What PPP actually does to the scoreboard: Nominal converts incomes at exchange rates; PPP re-prices them by local cost of living — a swap that can move a country's figure by 50% or more and reshuffles the entire top 10.
  2. Singapore's PPP coronation: Adjusted for purchasing power, Singapore jumps past Luxembourg to No. 1 among sovereign states at about $157K per person (IMF, 2025), with Luxembourg (~$152K) and Ireland (~$148K) trailing.
  3. PPP's winners and losers: Qatar surges, Switzerland slides: Cheap-at-home Qatar rockets to ~$122K under PPP while famously expensive Switzerland — 3rd on the nominal table at ~$111K — slips down once Zurich prices eat the difference.
