Zurich consistently holds the title of the wealthiest and most expensive city in Switzerland. As a global financial powerhouse, Zurich serves as the headquarters for numerous international banks and insurance giants, leading to a GDP per capita that far exceeds the national average. In the 2026 global cost-of-living indices, Zurich frequently ranks as the most expensive city in the world, surpassing even New York and Singapore. This wealth is reflected in the city's pristine infrastructure, world-class public transport, and the ultra-luxury boutiques of the Bahnhofstrasse. However, if "richest" is measured by the concentration of ultra-high-net-worth individuals, the city of Zug—located just south of Zurich—is often cited due to its status as a tax haven with the highest density of millionaires and "crypto-valley" startups. While Zurich is the center of institutional wealth and high wages, Zug and the municipalities along the "Goldcoast" of Lake Zurich are where much of Switzerland's private billionaire wealth is physically located.
