This paper constructs homogeneous time series of global household offshore wealth covering the 2001–2023 period, during which major international efforts were implemented to curb offshore tax evasion. We find that: (i) global offshore wealth remained broadly stable as a fraction of global GDP since 2001, following a sharp increase in the 1980s and 1990s; (ii) the location of offshore wealth changed markedly, with a decline in the share held in Switzerland and a rise of Asian financial centers, the United Kingdom, and the United States; and (iii) a growing fraction comes from developing countries.
