GBTC is trading 3.5% down as Bitcoin falls amid rising Treasury yields.
- Bitcoin fell about 1.58% on September 15, 2026.
- The 10-year Treasury yield is near 5%, pressuring speculative assets as investors position ahead of the Federal Reserve’s September 15–16 meeting, where markets price a high probability of a rate hike.
- The move is sector-wide rather than company-specific; investors are also watching the Senate’s September 15 CLARITY Act vote, adding event risk.
