Bitcoin ETFs End Six-Week Inflow Streak with $1 Billion Net Outflow

US spot Bitcoin ETFs experienced their largest weekly net outflow since January, with a total of $1 billion in withdrawals for the week ending May 15. This marked the end of a six-week streak of inflows that saw investors pour in a total of $3.4 billion.

The reversal was largely driven by macroeconomic factors, including surging Treasury yields and higher-than-expected inflation data. The 10-year Treasury yield reached its highest level since May 2025 at 4.54%, while the Consumer Price Index (CPI) came in at 3.8%.

The outflows were widespread among Bitcoin ETFs, with all 11 products experiencing net withdrawals on their final trading day of the week. Ethereum ETFs also saw significant outflows, adding to the sector's cautious sentiment.

Despite this short-term setback, institutional investors remain optimistic about the potential for increased crypto ETF inflows in the coming months. According to a recent survey by Nickel Digital, 86% of institutional allocators and wealth managers expect crypto ETF inflows to rise through 2026 as regulatory clarity improves.
