What ETF flows actually measure
A crypto ETF flow is the net change in shares outstanding, so it measures demand for the ETF wrapper.
- Inflows: authorized participants create new ETF shares.
- Outflows: shares are redeemed with the fund.
- Creation and redemption happen in large blocks.
Reading flows against price
Flows and price often move together, but they can move apart.
Spot versus futures ETF flows
Spot and futures crypto ETFs are built differently, so their flows mean different things. The table compares the two.
Limits of flow data
Flow data does not arrive in real time. Figures are published after the trading day and can lag by hours.
Who regulates crypto ETFs
In the United States, the SEC must approve a crypto ETF before it can list. The agency approved the first US spot bitcoin ETFs in January 2024 and spot ether ETFs in May 2024. A qualified custodian holds the coins.
