The sale occurred against the backdrop of growing market uncertainty triggered by a wave of U.S. tariffs that rattled global trade and risk assets.

Notably, the filing’s cutoff date—March 31—came just two days before the so-called ‘Liberation Day’ on April 2, 2025—a reference to the day the U.S. imposed comprehensive tariffs affecting nearly all its major trading partners.

The SEC filing, dated May 15, confirms SWIB sold its Bitcoin ETF holdings ahead of the March 31 reporting date for the end of the first quarter of the year.

According to the board's previous filing, dated February 14, the fund held 6,060,351 IBIT shares, worth approximately $321,501,621.
