Expatriates moving to Switzerland—home to some of the biggest private banks, commodity traders and pharmaceuticals companies—earn an average of more than $193,000. That's the highest in the world and 54% more than if they'd stayed at home, a study published Wednesday by HSBC Holdings Plc shows. That boost in remuneration is only surpassed by the 58% increase enjoyed by expats relocating to Saudi Arabia's petrodollar economy.

Switzerland leads HSBC's economics ranking—measuring issues from personal finances and career progression to the strength of the local economy—for a third straight year. Almost eight in 10 expats said they had more disposable income after moving to the home of Credit Suisse Group, drugmaker Roche Holding and commodities trader Mercuria Energy Group Ltd.
