Q3 2026: The Great Fiduciary Migration & Decanting Acceleration

Published August 16, 2026 · Authored by the South Dakota Strategies Fiduciary Research Bureau

South Dakota continues to widen its structural lead as the preeminent trust situs in the global wealth architecture. Data compiled from the South Dakota Division of Banking and regional economic indicators from the Minneapolis Federal Reserve confirms that aggregate trust capital administered by South Dakota chartered trust companies reached an all-time high of $3.85 Trillion in Q3 2026.

The structural catalyst remains the looming expiration of federal estate tax exemptions alongside aggressive state-level wealth and franchise tax proposals in California, New York, and Illinois. Families with multigenerational wealth are utilizing South Dakota's statutory decanting provisions (SDCL 55-57A) to migrate legacy trusts into perpetual structures governed by SDCL 43-5-8.

Furthermore, the formation of chartered and non-chartered Private Trust Companies (PTCs) under SDCL 51A-6A has accelerated by 22% over the trailing 12 months. Single-family offices managing $250M+ cite the state's minimum capital requirement ($200k-$500k) and directed trust liability protections (SDCL 55-1B) as the decisive factor over Delaware and Nevada.
