Spot Bitcoin exchange-traded funds (ETFs) have witnessed substantial outflows totaling $1.7 billion over the last four weeks, marking a significant trend in the cryptocurrency market. Matthew Pinnock, chief operating officer of Altura DeFi, indicated that these redemptions are primarily driven by a 'macro-driven repricing of risk' rather than any specific issues with Bitcoin itself. The IBIT ETF has been particularly affected, accounting for the majority of the outflows due to its scale and liquidity, making it a preferred option for institutional investors adjusting their portfolios. This trend aligns with broader economic indicators, including stronger-than-expected US employment data and rising Treasury yields, which have led to a shift in institutional risk appetite. In addition to Bitcoin, spot Ether ETFs have also experienced four consecutive weeks of redemptions, losing approximately $885.6 million in total. In contrast, some altcoin ETFs, such as HYPE, reported net inflows of $16.65 million during the same period, indicating varied investor sentiment across different cryptocurrency products.
