The family-office layer connecting Israel and the diaspora is operating in active reorganization.
The 2026 aliyah tax reform pulls UHNW principals and their structures toward Israeli tax residency. The 10-year foreign-source exemption preserves offshore positions for a decade after arrival. The new worldwide disclosure regime, in force from January 1, 2026, removes the reporting privacy that prior cohorts enjoyed.
The architecture is global by design. Wealth is typically held across multiple jurisdictions: Israel for residence and operating businesses; Switzerland and Liechtenstein for banking and trust structures; the United States or United Kingdom for investment vehicles; the Caribbean for select holding companies. The private banking stack is correspondingly cross-border. Pictet, Lombard Odier, J. Safra Sarasin, Edmond de Rothschild, and Julius Baer operate dedicated Israel and Jewish-wealth desks from Geneva and Zurich. Bank Leumi private banking, Mizrahi-Tefahot, and Discount serve the domestic side.
Succession is the ongoing variable. The first generation of Israeli post-1948 wealth is transitioning to second and third generations, often spread across continents. Diaspora UHNW families face the same problem in reverse.
Philanthropy completes the picture. Federations, the Jewish Agency, JNF, and a long list of named foundations sit alongside or inside family-office structures.
