Zurich: the world's most expensive Big Mac, in the world's most expensive city
Zurich consistently posts the highest USD-equivalent Big Mac price tracked anywhere — typically $8.00-$8.50 against the US base of $5.79. Zurich's commercial rent, real wages, and labor costs are the highest in Switzerland, which itself is the most expensive country in the dataset. The franc-denominated Zurich price has barely moved in 15 years; the dollar-equivalent fluctuates only as CHF strengthens or weakens.
Zurich is the cleanest illustration of why a high USD Big Mac doesn't signal currency overvaluation in any debasement sense. The Swiss National Bank has run one of the most restrained money-supply policies in the developed world, and Zurich's burger reflects that discipline. The price is high because Swiss wages are high — not because the franc is being printed faster than its productive base supports.
