This Week in Crypto (August 17–24): The SEC Publishes Regulation Crypto Assets, $4B of Shorts Get Liquidated, and a DeFi Vault Gets Voted Out of Its Own Money

If last week in crypto was about things that didn't happen, this week was about all of them happening at once. The SEC meeting canceled on August 13 returned on August 18 as a published proposal, with no meeting at all. The Treasury doubled its bond buybacks, and bitcoin ran from $62,300 to nearly $80,000 on the largest short liquidation since 2021. ETFs took their best week in ten months, and a lending protocol lost $8.5 million to a vote. Here's the week.

The week at a glance

The SEC published the rule five days after canceling the meeting to propose it

On August 18 the SEC proposed Regulation Crypto Assets, its first substantive crypto rulemaking — by written vote, with no open meeting at all. The meeting meant to do this was pulled on August 13 with no replacement date, which is where we left it seven days ago. Atkins, Peirce and Uyeda advanced it with no dissent, on a Commission entirely Republican since Caroline Crenshaw left in January 2026.

On X: @SECGov — the proposal creates "a clear and fit-for-purpose framework for certain investment contracts involving crypto assets."

The exemptions came in narrower than pre-proposal coverage suggested.

The larger provision is the safe harbor. A token sold as a covered investment contract — a crypto asset paired with a promise of future managerial effort — can stop being one. The issuer finishes the work, stops representing that more is coming, and files a report on Form TR; the contract is then "deemed by the Commission to have ceased to exist." Rule 103 attaches ten disclosure topics.

On X: @SECPaulSAtkins — the aim is "clear pathways to raise capital under the federal securities laws."

None of it is law yet; comments close October 20, 2026. So the question a founder would actually ask — can I raise on this today? — still answers no. What changed is that there is now a document to argue about instead of a rumor.

Bitcoin's biggest week in two years started in the bond market

Bitcoin opened near $62,300 and traded close to $80,000 by Friday, August 21 — a gain reported between 20% and 25% depending on the window, the largest since March 2024. Ether ran harder, up 18% in a day and later above $2,500.

The trigger was a bond announcement. On August 19 the Treasury said it would double buybacks of longer-dated debt, from $2 billion to $4 billion per operation. The 30-year yield fell from a 19-year high of 5.34% to 5.196%. Secretary Scott Bessent named the intent the next day: "part of it is signaling here — to show that we believe that the yields don't reflect the underlying fundamentals."

Leverage did the rest. On August 20, $3 billion of shorts were liquidated in 24 hours against $263.5 million of longs — the largest short liquidation since at least 2021 — and another $1 billion went the next day.

On X: @KobeissiLetter — crypto's "7th largest liquidation event in history," $3.5 billion in 24 hours, +$280 billion of market cap.

The traders who got hurt were right on direction for six weeks and wrong for two days; our guide to perps, leverage and funding rates covers why. Note what this rally was not: nothing that moved price started inside crypto — equally true last week, when a Bank of Japan signal pushed bitcoin to $62,854.

Trump asked Congress for the CLARITY Act, and named Hyperliquid

On Wednesday, August 19, Trump hosted crypto and finance executives at the White House and called on Congress to pass the Digital Asset Market Clarity Act — "a fair version of the Clarity Act," framed as keeping the US ahead of China. Coinbase, Ripple, Robinhood and Gemini were in the room, alongside Atkins and CFTC Chair Mike Selig.

The arithmetic did not change. The bill sits at 51 of the 60 votes needed ahead of a September 15 procedural vote, stalled on an ethics fight over banning officials from operating crypto businesses. An endorsement is not a vote.

The sharper headline was Hyperliquid. Trump said Selig's CFTC is working to bring the exchange onshore "in a fully compliant and legal fashion," and HYPE rose about 19% to $69.56. We'd note nothing is filed behind it — no application, no approval, no timetable — and our beginner's guide to Hyperliquid covers what a compliant version would have to change.

On X: @WatcherGuru — a recap claiming Trump said the US is considering buying "sizable" amounts of bitcoin.

Flag that one as uncorroborated: no outlet with a reporter in the room confirmed it, and the Strategic Bitcoin Reserve is funded by forfeited bitcoin, not by open-market buying the executive branch cannot authorize alone.

Spot ETFs took their best week since October 2025

US spot bitcoin ETFs pulled in roughly $1.92 billion across August 17–21, their strongest week in ten months, against $389.7 million of outflows seven days earlier.

Ether funds added $697.5 million, also their largest week since October 2025. BlackRock dominated both: IBIT took $503 million on August 20 alone — 83% of that day's total — and ETHA led Friday's ether flows with $151 million. Combined, the two complexes drew $2.615 billion, and weekly ETF volume more than tripled to $29 billion.

On X: @FarsideUK — August 20: total +$606.3M, IBIT +$503M, FBTC +$64.7M, BITB +$26.4M.

One caveat: Farside prints $454.8M for Wednesday against the $517.2M above — a provider difference, not a correction. And a flow print measures fund plumbing over five sessions, not conviction; the same wrapper produced the opposite result a week ago. It says nothing about who controls the coins, which is the difference between custodial exposure and self-custody an ETF quietly removes.

The kicker: Term Labs lost $8.5M and nothing was broken

On August 23, DeFi lending protocol Term Labs confirmed roughly $8.5 million was drained from its vaults. No smart-contract bug, no reentrancy, no oracle manipulation: the attacker bought enough governance voting power to approve the transfers, and the vaults complied, because that is what they are built to do.

The haul was 2,843 ETH (about $6.87 million) plus 1.68 million USDC, swapped into roughly 1.6 million DAI. PeckShield traced the attacker's funding to 2 ETH routed through Tornado Cash. It hit Term Vaults, built on Yearn v3, not the core repo lending market.

DefiLlama had logged 17 August incidents worth $18.8 million before this one, against 38 costing $254 million in July. On August 18 an attacker also hit MAYAChain with one deposit carrying 23 messages, chaining six bugs for $1.7 million; CACAO fell 88%.

The week's uncomfortable rhyme: the SEC spent Tuesday designing a legal path toward decentralized governance, and Sunday's largest theft ran through it. Voting power is an attack surface with a market price, and depositors in any DeFi lending vault are exposed to whoever can afford to buy it.

Also this week

• Strategy swung from a $13 billion paper loss to a $1.4 billion profit. It holds 840,447 BTC at an average of $75,385; near $77,300 on August 21 that sat 2.4% above cost, reversing the $9.5 billion deficit we recorded last week.
• Musk's X is exploring paying creators in stablecoins. Reporting points to talks around USDC for creator royalties; X has confirmed nothing. Meta already pays select creators in USDC on Solana and Polygon.
• The Hashdex Bitcoin ETF stopped trading. DEFI left NYSE Arca on August 17 and began selling its bitcoin on August 18 — into the first two days of a 22% rally.
• Sentiment started the week in Fear. The Fear & Greed Index read 30 on August 17, before the reversal erased the move.

What to watch next

Four dates. August 28: Kevin Warsh's first Jackson Hole keynote as Fed Chair, at a symposium themed "Financial Innovation: Implications for Payments and Policy." September 9: the first scaled Treasury buyback — 30-year yields erased their entire post-announcement decline by August 20, so this week's driver is unproven. September 15: CLARITY cloture, nine votes short. October 20: comments close on Regulation Crypto Assets. If you plan to hold through a Warsh headline rather than trade it, our guide to custodial versus non-custodial wallets is a reasonable place to start.
