US Bitcoin Spot ETF Sees $93.1 Million Cumulative Net Inflows in the Week

US Bitcoin spot ETFs saw a cumulative net inflow of $93.1 million in the week ending March 21, despite a $163.5 million outflow on Wednesday. This outflow marked the end of a seven-day inflow streak that had accumulated nearly $1.2 billion. The outflow came as Bitcoin fell below $71,000, reflecting investor caution in response to rising inflation and geopolitical tensions.

The inflow streak extended to seven consecutive days earlier in the week, with $199.4 million flowing into the funds on Monday alone. This brought the total inflow to $1.2 billion, the longest such streak since September 2025. However, the positive momentum reversed mid-week as macroeconomic pressures, particularly higher-than-expected producer price index (PPI) data and geopolitical tensions, weighed on market sentiment.

Federal Reserve Chair Jerome Powell emphasized that inflation remains a concern and that the central bank is maintaining a higher-for-longer interest rate environment. This stance has kept investors cautious, contributing to the outflow on Wednesday. Despite this, institutional interest in Bitcoin remains strong, with BlackRock's iShares Bitcoin Trust (IBIT) receiving $169 million in inflows.

Why Did This Happen?

Bitcoin's price fell over 8% from weekly highs above $75,000 amid rising oil prices and elevated inflation expectations. This led to a more defensive stance among investors and increased outflows from Bitcoin ETFs. The outflow was led by Fidelity's fund, which saw $104 million in redemptions, followed by BlackRock's iShares Bitcoin Trust, which lost $34 million.

The broader market environment, including geopolitical tensions in the Middle East, has also impacted investor confidence. Short-term macroeconomic factors have challenged Bitcoin's ability to maintain elevated prices, even as institutional demand continues.

How Did Markets React?

Despite the mid-week outflow, Bitcoin stabilized above $71,000 by the end of the week. Institutional and retail demand for Bitcoin ETFs showed resilience, with inflows continuing in the days following the outflow. Ethereum and Solana ETFs also saw inflows, indicating a broader interest in crypto-related investment products.

Crypto ETPs recorded $1.06 billion in inflows last week, highlighting Bitcoin's growing appeal as a relative safe-haven asset. This reflects increased institutional and retail interest in regulated crypto products.

What Are Analysts Watching Next?

Analysts are monitoring the impact of the Federal Reserve's stance on inflation and interest rates, which will influence investor sentiment in the near term. Rising oil prices and geopolitical tensions remain key factors affecting Bitcoin's price.

Regulatory developments are also being watched closely, as the SEC and CFTC issued guidance classifying most cryptocurrencies as non-securities, potentially boosting investor confidence. The maturing market structure and increased institutional adoption are seen as positive indicators for long-term price stability.
