Bitcoin ETF outflows that dragged BTC to a 2026 low below $60,000 in the first week of June may have less to do with a rotation into upcoming IPOs like SpaceX than with the unwinding of cash-and-carry arbitrage trades, according to Fabian Dori, chief investment officer at Swiss digital asset bank Sygnum.
The selling pressure took bitcoin more than 50% below its October all-time high near $125,000. One widely circulated explanation has been that investors are selling BTC to free up capital for highly anticipated listings, with SpaceX (SPCX) due to price on Friday. Dori disputes that read in an interview with CoinDesk, pointing to on-chain and derivatives data he says tells a different story.
Why it matters
If true, the framing matters for how the rest of the cycle is read. ETF outflows are typically treated as a sentiment barometer — investors redeeming their BTC exposure suggest risk-off behavior across the asset class. Dori's argument is that a significant slice of recent outflows is mechanical: institutional cash-and-carry trades that bought spot BTC through ETFs while shorting CME futures, then unwound as futures premiums and funding rates compressed.
That distinction would mean the capital isn't leaving crypto, it's just leaving a specific trade. Exchange balances remain broadly normal, stablecoin supply shows little meaningful contraction, and riskier corners of the digital asset market continue to attract inflows — none of which lines up with a broad capital migration into IPO allocations.
Market impact
Dori pointed to a parallel decline in CME bitcoin futures open interest alongside ETF redemptions as perhaps the strongest evidence. Open interest and funding rates moved together over the same period, suggesting a meaningful share of ETF flows are tied to carry-trade unwinds rather than directional bearishness. When the futures premium narrows or funding conditions turn less attractive, traders sell spot exposure and close futures shorts, generating redemptions that look identical from the outside to outright selling.
Frequently asked questions
-
What is the cash-and-carry trade driving bitcoin ETF outflows?
It's an institutional arbitrage in which a desk buys spot bitcoin, often through an ETF, and simultaneously shorts CME bitcoin futures to collect the basis. When futures premiums narrow or funding turns less attractive, traders unwind by selling spot and closing futures, which generates ETF redemptions that look like…

Why does Sygnum's CIO think ETF outflows aren't an IPO rotation?
Fabian Dori argues exchange balances are broadly normal, stablecoin supply has barely contracted, and riskier crypto products are still seeing inflows — none of which lines up with broad capital migration. The stronger fingerprint, he says, is CME futures open interest falling in step with ETF redemptions.
-
How low did bitcoin go during the recent ETF outflows?
Bitcoin fell to a 2026 low below $60,000 in the first week of June, more than 50% below its October all-time high near $125,000, according to CoinDesk reporting.
-
What evidence links ETF outflows to arbitrage unwinds?
Dori points to a parallel decline in CME bitcoin futures open interest alongside ETF redemptions, with open interest and funding rates moving together over the same period — a pattern consistent with carry trades closing rather than directional sellers exiting.
-
What would it take for bitcoin ETF flows to stabilize?
Under Dori's framing, recovery depends partly on whether CME futures premiums and funding rates re-widen enough to make the cash-and-carry trade attractive again, which would draw fresh institutional basis capital back into spot bitcoin ETFs.
