Brokers from Axstera dive into the latest cryptocurrency market movements as U.S. spot Bitcoin exchange-traded funds (ETFs) experienced a remarkable surge in investor activity. On Monday, Bitcoin ETFs recorded a net inflow of $368 million, marking the largest single-day capital increase since early August.
This development underscores renewed institutional confidence in Bitcoin as investors anticipate potential monetary policy changes from the Federal Reserve.
All twelve spot Bitcoin ETFs tracked during the session reported positive inflows, highlighting a broad-based buying trend among institutional participants. Fidelity’s FBTC emerged as the top performer, drawing $156.5 million in fresh capital.
It was closely followed by Ark Invest and 21Shares’ ARKB, which combined for $89.47 million in inflows. This concentration of buying suggests that large investors are strategically positioning themselves in Bitcoin ahead of crucial macroeconomic events, particularly the upcoming Federal Reserve interest rate decision scheduled for September 17.
The inflow comes after two consecutive days of ETF outflows, signaling a sudden reversal in investor sentiment. Many analysts interpret the surge as a hedging strategy, with Bitcoin seen as a safer asset compared to other cryptocurrencies in the current macroeconomic climate.
This trend is further reinforced by short-dated implied volatility for Bitcoin, which spiked by 15% over the weekend, indicating that options traders are bracing for significant price movements in the near term.

Meanwhile, Ethereum ETFs presented a stark contrast to the bullish momentum in Bitcoin. The sector experienced a negative net flow of $96.69 million, marking the sixth consecutive day of withdrawals.
This shift reflects a rotation of capital from Ethereum to Bitcoin, driven by risk-averse sentiment among institutional investors. “Investors previously chased Ethereum for higher potential gains during periods of strong sentiment, but are now favoring Bitcoin as a safer option ahead of the Fed announcement,” explained an analyst from the team.
This capital rotation highlights a broader trend in the crypto markets where funds migrate between assets based on anticipated macroeconomic impacts.
With key economic indicators such as Nonfarm Payrolls revisions, the Producer Price Index, and the Consumer Price Index being released this week, investors are recalibrating their portfolios to manage risk and optimize returns. These macroeconomic events will likely dictate short-term positioning in both Bitcoin and Ethereum ETFs.
The strong inflows into Bitcoin ETFs underscore the growing influence of institutional money in shaping cryptocurrency markets. Unlike retail traders, who often react to short-term price swings, institutional investors tend to make calculated decisions based on macroeconomic trends and risk management strategies.
This dynamic was evident in the current inflow pattern, where the movement of large sums of capital significantly outpaced typical daily trading volumes, signaling strategic positioning rather than speculative behavior.
From a technical perspective, Bitcoin is currently trading around $112,654, reflecting a modest gain of 0.8% on the day. Ethereum, on the other hand, is changing hands at approximately $4,348, up 1.1% in the past 24 hours.
While both cryptocurrencies are experiencing gains, the stark difference in ETF inflows suggests that institutional investors perceive Bitcoin as the safer vehicle to weather potential volatility in the coming weeks.
Market psychology is a driving factor. With the Federal Reserve’s interest rate decision looming, many investors are adjusting positions to reduce exposure to riskier assets.
Bitcoin’s established reputation as the leading digital currency provides a relative sense of stability, whereas Ethereum, with its broader exposure to decentralized applications and network-specific risks, is currently less favored for institutional allocations.

Looking ahead, the market is expected to remain sensitive to macroeconomic announcements. Analysts predict that any signs of an accelerated rate cut or stronger inflation signals could further influence capital flows between Bitcoin and Ethereum.
The short-term implied volatility suggests that options markets are pricing in substantial price movements, making strategic positioning in ETFs a critical factor for investors seeking both security and potential upside.
For investors and traders looking to navigate these developments, closely monitoring institutional inflows, market volatility, and macroeconomic indicators is crucial. Understanding how large capital movements correlate with economic reports can provide valuable insights for timing trades and managing portfolio risk effectively.
In conclusion, the $368 million inflow into Bitcoin ETFs reflects a pronounced shift in investor sentiment as the market anticipates upcoming Federal Reserve decisions.
While Ethereum ETFs face continued outflows, Bitcoin’s position as a relatively safer asset is being reinforced. This pattern of capital rotation and heightened volatility is likely to continue until key macroeconomic data is released and the Fed clarifies its policy stance. Investors should remain vigilant, monitor ETF trends, and prepare for potential market swings in the days ahead.
