The Grayscale Zcash Trust (ZCSH) recorded $11.42 billion in trading volume for the week ending September 18, 2026, accounting for 32.5% of all spot crypto ETF turnover. While the fund has seen rapid growth, the surge was heavily concentrated on September 16, driven by macroeconomic volatility and legislative developments.
The volume spike was triggered by a 25 basis point Fed rate hike and the Senate's rejection of the CLARITY Act, which prompted traders to use the new, liquid ZCSH fund for rapid position adjustments.
