What Happened to Bitcoin and Ethereum ETFs During the Crucial Macro Week?

Market impact: mixed, with a short-term bullish bias for BTC but weaker confirmation from the broader crypto complex.

The key signal is the sharp reversal in spot Bitcoin ETF flows: after roughly $746 million of combined outflows on Tuesday and Wednesday, Friday attracted $433 million, leaving the week only marginally positive at about $6 million. That suggests institutional demand remained responsive to a rebound in sentiment, but the near-flat weekly balance indicates that conviction was not consistently strong throughout the macro event risk.

For BTCUSD, the Friday inflow is constructive because ETF creations provide a direct source of spot-market demand and coincided with Bitcoin rising from approximately $76,000 to above $80,000. However, the move may partly reflect short covering, tactical reallocation, or relief after the Federal Reserve event rather than a durable shift toward risk assets. The failure of the week to generate substantial net inflows limits the strength of the bullish interpretation.

The more cautious signal comes from Ethereum ETFs, which recorded approximately $140 million of weekly outflows despite positive flows on Monday and Friday. This divergence implies that investors may be favoring Bitcoin as the more liquid or institutionally established crypto exposure, while reducing exposure to higher-beta assets. If sustained, that could mean weaker relative performance for ETH and other altcoins even if BTC remains supported.

The failed CLARITY Act vote is a regulatory overhang for the sector, while the reported Fed rate hike reinforces the importance of liquidity and real-yield expectations. These factors can produce renewed selling if markets interpret policy as restrictive or if regulatory uncertainty intensifies. Conversely, continued BTC ETF inflows after those shocks would strengthen the case that institutional demand is absorbing macro-driven supply.

What traders should monitor next:

whether Bitcoin ETF inflows remain positive for several sessions rather than only one day; whether ETH flows stabilize; the market’s reaction to subsequent Fed guidance and rate expectations; and whether BTC can hold its rebound without renewed ETF redemptions. The current evidence supports a near-term BTC-relative-strength interpretation, but not yet a confirmed, broad-based crypto bull signal.
