U.S.-traded spot Ethereum exchange-traded funds (ETFs) experienced persistent outflows in late September and mid-October, periods that coincided with relative weakness in the ETH/BTC ratio.
Still, inflows outside the United States and continued growth in stakes have muted the impact on prices, suggesting that headwinds are episodic rather than structural.
The question of whether ETF redemptions are driving Ether’s underperformance relative to Bitcoin requires analyzing flow data alongside derivatives positioning, supply well staking, and regional divergences.
ETF creations and redemptions reflect the activity of authorized participants rather than direct buying or selling, and their relationship to price depends on the broader structure of the market, such as funding rates, basis spreads and competing return opportunities.
Data shows that exit windows correspond to ETH/BTC weakness as derivatives positioning turns negative, but European capital inflows and purchases have repeatedly absorbed U.S. selling pressure, limiting transmission of spot flows.
Feed templates and calendar
US Spot Ether ETFs oscillated between strong inflows in July and August and multi-week exit periods in late September and mid-October.
The week ending September 26 saw record U.S. redemptions of around $796 million, concentrated in Grayscale’s ETHE as investors shifted to lower-fee products or exited their positions altogether.
Outflows resumed around October 23-24, with the week ending October 27 seeing approximately $169 million in net redemptions in US Ether ETPs.
These periods align with declines in ETH/BTC on a weekly close-to-close basis, supporting the hypothesis that the flows are carrying a price signal.
The opposite trend appeared at the beginning of October. The week ending October 6 generated approximately $1.48 billion in net inflows to the United States.
Ether ETFs in a broader risk environment, and ETH/BTC have stabilized or increased. This correlation between entries and relative strength, and exits and relative weakness, holds throughout the July-October window when grouped into weekly frequency.
However, the relationship is noisy at daily intervals and breaks down when regional or derived factors dominate.
Non-US Ether exchange-traded products complicate the story. Data from CoinShares shows that Germany, Switzerland and Canada absorbed Ether ETPs during U.S. outflows in mid-October, leading to net global inflows within weeks despite U.S. redemptions.
Hong Kong spot Ether ETFs remain smaller but add a second non-US data point as that market matures.
The regional divergence implies that US flows are necessary for price modeling but not sufficient, as global demand can offset domestic sales, particularly when European investors view declines as entry points.
Derivatives amplify flow signals
The relationship between ETF flows and ETH/BTC performance strengthens when the positioning of derivatives matches.
The open interest rates and perpetual funding rates of CME Ether futures act as amplifiers. When the three-month annualized basis moves into negative territory and funding rates become negative, outflow-induced pricing pressure intensifies.
Conversely, a positive basis and high funding can blunt the impact of buybacks by signaling speculative demand and a willingness to pay for leverage.
Data from CME Group shows that Ether futures open interest increased through October, reflecting increased institutional participation around flow cycles.
Weighted average perpetual funding rates tracked by aggregators turned negative during the late September outflow window and again in mid-October, suggesting that leveraged long positions were unwound alongside ETF redemptions.
This dual pressure, spot selling via ETF redemptions and derivatives deleveraging, appears to be behind the periods of strongest ETH/BTC underperformance.
When the basis and financing stabilize or become positive, the flow-price link weakens. The increase in inflows in early October corresponds to a shift to positive funding and a stronger base, and ETH/BTC has stopped falling despite mixed signals elsewhere in the crypto markets.
The interaction term between flow direction and derivatives positioning is more predictive than flows alone, consistent with previous research on Bitcoin ETFs, which found that flows explain about 32% of daily price variance when isolated, but gain explanatory power when combined with leverage measures.
Staking Tokens and Liquid Staking as Supply Dwindles
Ethereum’s Beacon Chain validator count continued to rise through October, with net inflows from validators absorbing ETH supply that might otherwise flow to exchanges or ETF redemption baskets.
Liquid staking token protocols, including Lido’s stETH, Coinbase’s cbETH, and Rocket Pool’s rETH, also saw supply growth during release windows, indicating that organic staking demand persisted regardless of ETF activity.
To quantify the compensation, it is necessary to compare the weekly variations of the outstanding ETH and LST staked with the weekly net flows of the ETFs.
Beacon Chain data shows validator additions equivalent to tens of thousands of ETH per week in September and October, while LST supply growth followed similar magnitudes.
When combined, staking sinks often matched or exceeded US ETF outflows each week, suggesting that buybacks removed ETH from exchange-traded wrappers without flooding spot markets as staking absorbed the freed-up supply.
Tokenized US Treasuries offering on-chain yields of 4-5% represent a competing destination for capital that might otherwise be allocated to ETH or Ether ETFs.
Real-world asset protocols have reported a Treasury token offering ranging from $5.5 billion to $8.6 billion through 2025, providing a risk-free rate alternative that can siphon inflows during periods where Ether’s total return lags short-term rates.
Competition is most acute among institutional allocators, who compare Ether ETFs to tokenized money market instruments, especially when ETH volatility increases or the ETH/BTC ratio stagnates.
Measuring the flow-price relationship requires weekly aggregation to smooth out intraday noise and alignment with ETH/BTC weekly closes to capture relative performance.
Correlations between weekly net ETF flows and weekly ETH/BTC returns are positive during the July-October window. However, the coefficient varies depending on whether derivative positioning and regional flows are included as controls.
Adding interaction terms for baseline and funding direction improves the fit, confirming that flows matter most when derivatives match.
ETF creations and redemptions reflect the activity of authorized participants in response to premium/discount dynamics and orders from end investors, not direct market making.
Daily feed printouts may be revised, and issuer-level differences in fees and tax batch structure create noise in the overall series.
The analysis also assumes that flows translate into spot purchases or sales, which occurs when authorized participants cover creation/redemption baskets in spot markets, but breaks down when hedging occurs via derivatives or over-the-counter desks.
The lag between reported flows and actual market impact can extend over several hours or even days, complicating intraday correlation testing and justifying weekly frequency as the appropriate unit of analysis.
What to watch next
ETF flows will continue to signal marginal changes in demand, but their predictive value depends on confirming signals from derivatives and regional data.
Weekly monitoring is expected to track US net flows, direction of non-US ETPs, on a three-month basis, weighted perpetual funding, and validator queue depth.
When U.S. capital outflows coincide with a negative base, negative funding, and stable stake growth, the headwinds intensify. When European or Canadian capital inflows offset American redemptions, or when staking absorbs the released supply, the impact on prices fades.
Catalysts that could overturn the flow regime include Ethereum protocol upgrades that affect the economics of staking, changes in US ETF fee structures that reduce ETHE’s cost disadvantage, or macroeconomic changes that compress Treasury yields and reduce RWA competition.
The relationship between flows and ETH/BTC also depends on the dynamics specific to Bitcoin ETFs. If Bitcoin ETFs see large inflows while Ether ETFs face redemptions, the relative underperformance worsens.
Tracking both asset classes in parallel provides the most accurate read on whether Ether-specific factors or broader crypto sentiment are driving the ratio.
Outflows from U.S. spot Ether ETFs match ETH/BTC weakness when derivatives positioning and regional flows align, but staking growth and non-U.S. purchases have repeatedly absorbed redemptions and limited spot price transmission.
Difficulties are real during periods of concentrated capital outflows with a negative base and funding, but they are episodic rather than structural.
Flows are more important as a risk indicator that confirms or contradicts signals from derivatives, staking, and cross-border demand, not as a standalone driver of Ether’s relative performance.
