- Bitcoin neared $80,000 and Ethereum topped $2,500 as macro and Washington catalysts boosted sentiment.
- Watch whether ETF inflows persist after Bitcoin’s 25% weekly advance and short-liquidation surge.
US spot Bitcoin and Ethereum ETFs recorded their strongest inflow week of 2026 as a sharp crypto rally pulled investors back into funds that had struggled to attract sustained demand for much of the year.
Bitcoin ETFs drew $1.918 billion in the five trading sessions through Aug. 21, while funds holding Ethereum attracted $697.2 million The combined $2.6 billion intake was the strongest for the two groups in about 10 months
Bitcoin funds recorded inflows every day during the week, pushing cumulative net subscriptions since their January 2024 debut to $53.7 billion. Notably, the weekly total was also their largest since the market selloff in October 2025.
Meanwhile, Ethereum funds also had their best showing since October, when they attracted nearly $1.3 billion during the week ended Oct. 3.
Notably, the renewed demand coincided with one of crypto’s strongest rallies in years. Bitcoin climbed from roughly $62,300 to briefly trade near $80,000 Friday, while Ethereum surged to a seven-month high above $2,500.
As of press time, digital asset prices had slightly retraced, with Bitcoin trading near $76,550 and Ethereum around $2,400
Washington policy rush and falling yields drive ETF demand
Bitcoin’s surge and the accompanying ETF inflows were fueled by a rare convergence of macro and policy catalysts, including falling Treasury yields, fresh White House support for crypto and a regulatory push from the SEC and CFTC.
BTC’s rally accelerated after the US Treasury said Aug. 19 that it would double the maximum size of liquidity-support buybacks for 10- to 20-year and 20- to 30-year securities to at least $4 billion per operation. Long-term yields fell after the announcement, easing financial conditions and lifting demand for Bitcoin and other risk assets.
Market momentum further strengthened after President Donald Trump met crypto executives at the White House and said the US was considering accumulating large amounts of Bitcoin and other cryptocurrencies.
While the comments did not create new authority for open-market purchases, they reinforced expectations that the administration intends to expand the government’s role in digital assets.
Washington also advanced two regulatory initiatives during the week. The SEC proposed Regulation Crypto Assets on Aug. 18, its first tailored framework for crypto fundraising, including exemptions and a conditional safe harbor for qualifying token offerings.
Two days later, the CFTC convened the first meeting of its Innovation Advisory Committee, where crypto regulation was among the main topics.
The gathering included executives from Coinbase, Uniswap Labs and BitGo and added to signs that US regulators are moving toward formal rulemaking after years dominated by enforcement actions.
Together, the Treasury move and the policy announcements gave investors several reasons to reprice crypto risk at once.
ETF buyers arrive as Bitcoin clears a key barrier
Meanwhile, the timing of the inflows strengthened the case that BTC’s rally was drawing fresh investment rather than relying solely on traders being forced out of bearish positions.
Bitcoin reclaimed its 200-day moving average during the advance after failing to hold above the closely watched trend line earlier this year. At the same time, billions of dollars of leveraged short positions were liquidated as prices accelerated.
Ecoinometrics, a Bitcoin-focused research platform, said ETF demand had been gradually recovering during August but remained modest until the final sessions of the week, when buying accelerated alongside the technical breakout.
That combination is important because a rally driven primarily by short covering can lose momentum once bearish positions have been cleared. Persistent ETF subscriptions represent new capital entering the market and can provide a more durable
Ecoinometrics’ ETF-flow model now places Bitcoin in a supported range of roughly $67,000 to $78,000, with an estimated fair value near $72,000. The firm said continued ETF buying could lift that range further if rising prices bring trend-following investors back into the market.
The shift is particularly notable given Bitcoin’s performance earlier this year. ETF demand weakened during the downturn from the cryptocurrency’s October 2025 record, leaving the market without one of the large structural buyers that had helped drive previous advances.
This week’s $1.9 billion intake suggests that channel has reopened, though one strong week does not establish a lasting reversal. The next test will be whether subscriptions remain positive after Bitcoin’s roughly 25% weekly advance and once the forced liquidation of bearish positions subsides.
