Bitcoin has spent the past week doing something it has not done since spring: forcing traders to ask whether a genuine turn has begun. The token pushed above $80,000 on August 25, and BitMEX co-founder Arthur Hayes says the answer is simple. In an essay published that day, Hayes argued that a Bitcoin bull market is already underway, and that the trigger wasn’t a regulatory breakthrough or a Fed rate cut — it was a technical adjustment to how the US Treasury buys back its own bonds.
Summary
Key takeaways
- Treasury Secretary Scott Bessent raised the long-end bond buyback limit from $2 billion to at least $4 billion per operation, effective between September 9 and November 4, 2026.
- Bitcoin jumped roughly 8.7% immediately after the August 19 announcement, climbing from around $64,000 toward $69,750–$71,000, then rallied further to top $80,000 by August 25.
- US spot Bitcoin ETFs pulled in about $517 million in net inflows on August 19, the strongest single-day intake since early May.
- More than $4 billion in crypto short positions were liquidated as the rally accelerated.
- Hayes points to the Treasury General Account, holding roughly $940 billion to $1 trillion, as a potential source of further liquidity if drawn down for future buybacks.
Arthur Hayes Links Treasury Buybacks to a New Bitcoin Bull Market
Hayes’s essay, titled Same Same But Different, ties Bitcoin’s latest run directly to the Treasury’s decision to buy back more of its own longer-dated debt. He calls it the same playbook, dressed differently, that he says powered Bitcoin’s rally in late 2023 — and he argues it’s already repeating.
How Bond Buybacks Are Meant to Move Bitcoin Prices
The mechanics, according to Hayes, are straightforward. When the Treasury purchases older, longer-dated securities, it tends to push their prices up and their yields down. Lower yields make holding cash or bonds less rewarding, which in theory nudges investors toward riskier assets — Bitcoin among them. That’s the chain of cause and effect Hayes is betting on, and it’s the reasoning behind his claim that this Bitcoin bull market has real fuel behind it rather than just momentum trading.
Echoes of Janet Yellen’s 2023 Playbook
Hayes draws a direct comparison to former Treasury Secretary Janet Yellen’s approach in December 2023, when she leaned harder on short-term Treasury bill issuance instead of long-duration bonds. He says that shift pulled money out of the Federal Reserve’s Reverse Repo Program — which he estimates fell from roughly $2.5 trillion to about $100 billion by the time Bessent took office in January 2025 — and pushed it into private markets. That period, Hayes notes, coincided with rallies in both Bitcoin and the Nasdaq 100, even as the Fed held rates near 5.3% and kept shrinking its own balance sheet. If Bessent’s current approach follows a similar logic, Hayes argues, Bitcoin still has considerable room to climb. He was also blunt that the buyback size announced so far is too small on its own to move a $40 trillion debt market, and he expects the Treasury to keep expanding the pace of purchases rather than stop where it stands.
US Treasury Doubles Long-End Bond Buyback Limits
The policy shift that set off the debate is concrete and dated. On August 19, the Treasury confirmed it would at least double the ceiling on certain long-end liquidity-support buybacks, lifting the cap per operation from $2 billion to a minimum of $4 billion between September 9 and November 4.
Details of Scott Bessent’s Buyback Expansion
The Treasury’s August 5 refunding statement had already authorized up to $38 billion in liquidity-support purchases for the quarter, alongside as much as $25 billion in short-maturity cash-management buybacks. The August 19 update effectively sharpened the tool aimed specifically at longer-dated securities. Separately, the New York Fed has been running about $10 billion in reserve-management purchases during its current monthly operating window — a distinct operation meant to keep banking reserves ample, and not part of the Treasury’s buyback program itself.
Treasury Insists This Isn’t Stimulus
Here’s where the story gets contested. The Treasury frames this entirely as debt management — a way to keep the market for older securities liquid and to manage its own cash position, not a lever for loosening monetary policy. That framing sits in direct tension with Hayes’s read of events, which treats the buybacks as a liquidity injection functionally similar to easing, even though officials have not described it that way. Whether the mechanism actually behaves like Hayes expects will depend on how the September and October purchases play out, not on the announcement alone.
Bitcoin’s Reaction: Price Surge, ETF Inflows and Short Squeezes
Markets didn’t wait for confirmation. Bitcoin moved fast in the days after the August 19 announcement, and the price action is the clearest evidence Hayes has for his thesis — even if it doesn’t prove causation on its own.
From $64,000 to Above $80,000
Bitcoin climbed from around $64,000 before the announcement to roughly $69,750–$71,000 within days, an increase of about 8.7% tied specifically to the news. The move didn’t stop there. The rally accelerated through the following week, pushing Bitcoin above $80,000 by August 25, with an intraday high above $81,000 that day, before it settled closer to $79,000 as later reports came in. It marked the strongest weekly advance the token had seen in months.
Yields, Liquidations and Sentiment
Bond markets moved too, at least at first. The 10-year Treasury yield initially slid toward 4.65% and the 30-year toward 5.20%. But that decline didn’t hold. Yields partially recovered within a session or two, with the 10-year climbing back above its pre-announcement level — landing near 4.71%, with the 30-year around 5.24% as of the latest reporting. That partial rebound suggests the announced buyback sizes haven’t fundamentally eased the market’s broader worries about US borrowing and debt supply.
On the crypto side, the numbers were more dramatic. US spot Bitcoin ETFs booked about $517 million in net inflows on August 19 alone — their strongest single day since early May — while derivatives markets saw more than $4 billion in short positions forced out as the rally gathered pace. Regulatory developments and generally improving sentiment toward crypto also played a role, making it genuinely hard to separate how much of the move traces back to Treasury liquidity versus other tailwinds. No purchases under the enlarged limits had even occurred by the time Hayes published his essay — the new schedule doesn’t start until September.
The Treasury General Account Looms as a Bigger Wildcard
Hayes sees a much larger lever sitting untouched: the Treasury General Account, which holds somewhere between roughly $940 billion and $1 trillion depending on the source. He calls a large drawdown from that account the “middle road” among the options available to Bessent — more aggressive than doing nothing, but short of an unlimited bond-buying pledge, which Hayes says would only come into play if yields breached 5%. Deeper spending cuts, he adds, look unlikely given upcoming elections.
Bessent has said the Treasury could tap some of that cash for buybacks without disrupting its scheduled long-term debt auctions. But no plan has been announced to deploy the full balance, and no specific amount has been committed to purchases. The Treasury’s latest borrowing estimates assume a $950 billion cash balance by the end of September and $850 billion by year-end, with $739 billion in privately held net marketable debt expected during the current quarter and another $628 billion the quarter after. Using the TGA more aggressively could temporarily put more cash into the private banking system — though its lasting effect would hinge on how quickly the Treasury rebuilds that account through fresh debt issuance.
Maelstrom’s Maximum-Risk Bet and Hayes’s Warnings
Hayes isn’t just theorizing from the sidelines. He says his fund, Maelstrom, has shifted a quella che lui definisce esposizione al rischio massimale, mantenendo posizioni rilevanti in Bitcoin, Ether, Ethena ed Ether.fi. Egli hasn’t disclosed specific position sizes or offered independently verifiable portfolio records to back up the claim. Even so, Hayes was careful to temper his own conviction: he warned that continued gains wouldn’t rule out steep corrections along the way, and separately cautioned that leverage remains dangerous for anyone who isn’t trading full-time, given how sharply volatility could swing in either direction.
What to Watch Next: September 9 and November 4
Two dates now matter more than any headline. September 9 is when the larger buyback limits actually take effect — the point where theory turns into executed purchases. November 4 is the Treasury’s next quarterly refunding, when officials will decide whether to expand, hold, or scale back the program. Comparing real buyback volumes against Treasury yields, the size of the TGA, and Bitcoin’s price action over that stretch will offer the clearest test yet of whether Hayes’s liquidity thesis holds up — or whether the Treasury’s own description of the program as plain cash management turns out to be the more accurate read.
