in 1930s Germany, and what the bankers had to do to move capital out of the country.
.
The Warburg family’s experience in 1930s Germany is one of the most dramatic case studies of what Jewish banking dynasties—and many Jewish families—faced under rising Nazi power.
🏦 The Warburg Banking Empire in Crisis
The Warburgs were one of Europe’s most prominent banking families, operating M.M. Warburg & Co. in Hamburg since the late 18th century. As Hitler rose to power, their position as Jewish bankers became dangerous. By 1933, anti-Jewish laws, boycotts, and state harassment were escalating. Warburgs faced two main challenges:
- Preserving control of their bank despite “Aryanization” policies.
- Getting family wealth and client capital out of Germany before it could be seized.
The Nazis introduced strict capital controls—limiting foreign transfers, taxing assets leaving the country, and surveilling Jewish financial activity. This meant that moving money wasn’t as simple as wiring funds abroad; it required creativity, negotiation, and risk-taking.
✈️ Moving Capital Out of Germany
To protect assets, the Warburgs and other Jewish bankers used a variety of strategies:
- Complex foreign exchange transactions — using overseas affiliates and trading partners to settle accounts outside of Germany.
- Physical transfers of gold, bonds, and securities — sometimes personally escorting assets across borders.
- Negotiated exits — working with foreign governments and the Reichsbank to get permission for partial asset transfers (often sacrificing part of their fortune as a “flight tax”).
- Reinvestment abroad — placing money in London, Amsterdam, and New York, sometimes buying hard assets like real estate or foreign businesses to park value safely.
Max Warburg, the head of M.M. Warburg, was forced in 1938 to sell the family bank under Nazi “Aryanization” laws. Despite these pressures, they successfully relocated much of the family fortune abroad, establishing strong positions in the U.S. and UK.
🌍 The Broader Jewish Experience
The Warburgs’ ordeal mirrored that of thousands of Jewish families in Germany:
- Sudden exclusion from public life, professions, and businesses.
- Confiscatory taxes (Reich Flight Tax) imposed on emigrants.
- Scramble to liquidate assets before currency controls made them worthless.
- Mass migration — to the U.S., Palestine, Latin America, and elsewhere.
Many families lost everything. Those who acted early—like the Warburgs—saved a portion of their wealth and sometimes rebuilt abroad. Those who waited often saw their businesses and homes confiscated and faced deportation later.
🔑 Lessons from the Warburgs
The Warburg story is both tragic and inspiring:
- Speed matters — They acted quickly, even when it meant taking losses.
- Global networks are survival tools — Their international banking connections saved them.
- Adaptability is everything — They shifted from Hamburg to London and New York, re-establishing themselves as global financial players.
Their survival and rebuilding helped finance Jewish refugee support, cultural institutions, and even early Israeli statehood efforts.
