CoinShares: Crypto ETP/ETF Flows Flip Negative With $1.07B Weekly Outflows Through May 18

Crypto investment products posted their first weekly setback after six straight weeks of inflows. CoinShares said digital-asset ETPs and ETFs recorded $1.07B of net outflows in the week ended May 18, ending one of the year's longest sustained run-ups in demand. Bitcoin products accounted for the bulk of the redemptions at $982M. Ethereum followed with $249M in outflows, its largest single-week withdrawal since Jan. 30. The pullback was driven overwhelmingly by the U.S. CoinShares data showed U.S.-domiciled products saw about $1.14B of net outflows, more than the global total as other regions were net buyers. Switzerland registered $22.8M of inflows, Germany $22M, Canada $12.6M and the Netherlands $7.5M. That split points to a regional divergence in positioning: U.S. institutions appeared more responsive to last week's risk-off backdrop, while European allocators treated the decline as a buying opportunity. It also underscores that institutional crypto demand is increasingly fragmented by geography and risk framework, rather than moving as a single block. Altcoin flows diverged from the headline trend. XRP attracted $67.6M in inflows and Solana added $55.1M, together drawing more than $120M in new capital during a week when overall products saw more than $1B leave. The pattern suggests rotation within crypto rather than broad capitulation, with investors trimming exposure to the largest, most liquid assets while adding positions in tokens with distinct risk-reward profiles. CoinShares estimated digital-asset products brought in $47.2B of inflows during 2025, with the U.S. contributing more than $44.5B. The latest Bitcoin outflows cut year-to-date inflows to $3.9B, still positive but lower than the prior week. Bitcoin dominance hovered near 58% in May, or about 64% when adjusted for stablecoin market capitalization. CoinShares said the week's drawdown ranks as the third-largest weekly withdrawal of 2026 so far. The reversal coincided with broader macro pressures, including elevated inflation concerns and geopolitical tensions, conditions that often prompt rapid de-risking across risk assets. CoinShares head of research James Butterfill detailed the figures in the firm's weekly flows report. For investors, the key signal is speed: six consecutive weeks of inflows followed by a billion-dollar swing highlights how quickly institutional positioning can change. The concurrent inflows into XRP and Solana also suggest a market where institutions increasingly differentiate among crypto assets rather than treating the sector as a single trade, with potential implications for portfolio construction. In scale, a $1.07B weekly outflow against $47.2B of 2025 inflows is about 2.3% of the prior year's total—meaningful, but not systemic. Still, the concentration of selling in U.S.-domiciled products and in Bitcoin and Ethereum indicates the most institutionally owned segment may also be the most sensitive when macro conditions deteriorate. Key watchpoints in coming weeks include whether U.S.-based outflows ease or intensify, whether European inflows can expand enough to offset them, and whether the altcoin rotation persists or proves temporary.
