Global digital assets: August ETF and ETP review
A monthly column on the global crypto markets and ETF/ETP flows, brought to you by CoinDesk Indices, Trackinsight and ETF Express.
Joshua de Vos, Research Lead, CoinDesk, writes that August marked a decisive reversal in global crypto ETP flows, as a sharp mid-month repricing in spot markets pulled capital back into the asset class at a scale not seen at any point earlier in the year. According to TrackInsight data, global digital-asset investment products recorded USD6.10 billion in net inflows as total AUM rose to USD155.0 billion. The month’s inflows were sufficient on their own to reverse the cumulative net redemptions recorded across the first seven months of 2026, returning the year’s flow picture to positive territory.
The CoinDesk 20 Index (CD20), which captures a diversified cross-section of the top 20 digital assets, rose 26.48 per cent in August, while the more concentrated CoinDesk 5 Index (CD5) gained 26.34 per cent. Bitcoin advanced 25.04 per cent and Ether 32.62 per cent, with the bulk of the move compressed into three sessions between 19 and 21 August, during which bitcoin climbed 21.06 per cent from roughly USD64,700 to USD78,300.
Asset flows
According to data from TrackInsight, inflows were concentrated in bitcoin- and Ether-linked instruments, though the more notable development was the arrival of newly launched single-asset categories, with a debut Zcash product ranking third globally by monthly net flows.
Bitcoin: BTC-linked products recorded net inflows of USD3.31 billion, with total category AUM reaching USD120.6 billion. Bitcoin now accounts for 77.8 per cent of global crypto ETP assets, and the category absorbed 54 per cent of all net inflows during the month.
Ethereum: Ether-linked products attracted USD1.75 billion in net inflows, closing August with USD20.6 billion in aggregate AUM. On a flow-relative-to-AUM basis, ETH inflows ran at roughly three times the bitcoin rate, at 8.5 per cent of closing category assets against 2.7 per cent for BTC, a reversal of the pattern that characterised the first half of the year.
Altcoins: The newly listed Zcash ETF drew USD326.4 million in net inflows against closing AUM of USD354.9 million, effectively building its entire asset base within a single month. XRP-linked products attracted USD190.9 million (AUM: USD2.94B), Solana drew USD189.4 million (AUM: USD3.31 billion), Hyperliquid-linked products added USD83.2 million across 10 vehicles (AUM: USD542 million), and Chainlink products took in USD27.9 million (AUM: USD240 million).
Flows by geography
Americas: Net inflows of approximately USD5.86 billion, overwhelmingly driven by US-listed products (USD5.82 billion in subscriptions) with Canada adding USD39.1 million. US-domiciled vehicles closed the month with USD130.7 billion in AUM, representing 84.3 per cent of global market share.
Europe: Net inflows of approximately USD211 million, with regional AUM of USD17.08 billion. Germany led at USD78.6 million (AUM: USD2.10 billion), followed by Switzerland at USD55.8 million (AUM: USD4.80 billion), Jersey at USD49.3 million (AUM: USD4.85 billion), Ireland at USD33.5 million and Liechtenstein at USD15.2 million. Sweden was the sole material European outflow at USD18.6 million in redemptions.
APAC: Net inflows of approximately USD24.8 million, led by Australia at USD13.2 million (AUM: USD718 million) and Hong Kong at USD11.0 million (AUM: USD645 million). Regional AUM stood at USD1.39 billion, or under 1 per cent of the global total.
Flows by currency
USD: USD-denominated products recorded USD6.02 billion in net inflows, closing the month with USD145.9 billion in AUM, the dominant share of global crypto ETP assets.
CAD: CAD-denominated products recorded USD51.5 million in net inflows, with total AUM of USD5.02 billion.
EUR / AUD / SEK: EUR-denominated products recorded USD13.9 million in inflows (AUM: USD1.52 billion), AUD added USD13.2 million (AUM: USD718 million), and SEK was the only currency class in net redemption at USD5.4 million of outflows (AUM: USD1.75 billion).

Outlook
August’s move wiped short interest rather than building long interest. The US Treasury’s doubling of its bond buyback program from USD2 billion to USD4 billion revived the ‘debasement trade’ narrative and detonated a heavily short market: USD2.7 billion of bearish crypto bets were liquidated in the 24 hours to 20 August, the largest on record, with shorts comprising roughly 92 per cent of the total and bitcoin seeing its first billion-dollar day of short liquidations. Forced buying began the move; USD6.10 billion of spot ETP inflows sustained it. Binance’s BTC perpetual funding never exceeded its 0.01 per cent eight-hour baseline all month, so crowded longs never replaced the shorts.
Two implications follow. The move has front-run the four-year cycle modestly, much as spot bitcoin ETFs pulled halving momentum forward in 2024, and with funding showing no stress, the conventional late-cycle warning signal is not yet available. Within altcoins, Zcash has been the structural outperformer across spot and perpetual markets, gaining 85.63 per cent against the CD20’s 26.48 per cent, making the arrival and rapid growth of a listed ZEC vehicle a confirmation of that trend rather than a surprise. Momentum from here depends on spot demand persisting once the macro narrative is priced.
