Bitcoin Breaches $72,000 as Spot ETF Inflows Eclipse Last Quarter's Total in Six Sessions

The bid didn't flinch. Between Monday morning in Tokyo and the London close on Thursday, spot Bitcoin ETFs absorbed a net $6.1 billion — more than the entire Q1 figure reported by Farside Investors just three weeks ago. Price broke the $72,000 level on Coinbase during thin overnight liquidity and has refused to give it back.

"This is what a supply shock looks like when it's not theoretical," said Geoff Kendrick, head of FX & digital assets research at Standard Chartered, in a note to clients. "ETF desks are net long into what is structurally a deflating float."

The math behind the move

Miners produce approximately 450 BTC per day post-halving. The combined inflow across BlackRock's IBIT, Fidelity's FBTC, and ARK 21Shares' ARKB implied purchases of roughly 5,900 BTC per day this week — more than 13x daily new issuance.

"You cannot front-run a halving forever, but you can front-run a year's worth of it in a week." — @caitlin-long

The order books tell the same story. On Binance's BTC/USDT pair, the 2% depth on the bid has widened to an average of $81 million over the last four sessions, versus $42 million in mid-March.

What's next

Options markets are already re-pricing. The 25-delta risk reversal in BTC monthly options flipped decisively positive on Deribit on Wednesday, the strongest call skew since the ETF approval window in January 2024. Traders are positioning for $80,000 as the next technical waypoint — and for the first time in this cycle, the number no longer sounds ambitious.
