A bond buyback gave bitcoin its best week in over two years

Treasury Secretary Scott Bessent said the department will raise its buybacks of long-dated debt from $2 billion to at least $4 billion per operation, starting 9 September. The programme covers securities maturing in ten to thirty years. The 30-year yield had hit 5.337% on Tuesday, its highest since 2007, then eased back toward 5.189%. Bitcoin ran straight through the move: from under $64,000 to above $68,000 on Wednesday, with reportedly around $1.44 billion of short positions force-closed, most of it inside a single hour. Thursday opened near $69,289 and Friday printed an intraday high of $76,858, roughly 20% up on the week. Ether opened Thursday around $2,252. Total crypto market value sat near $2.56 trillion on Friday, with bitcoin at about 57.8% of it. US spot bitcoin ETFs took in about $606 million on 20 August after $517 million the day before, and ether ETFs added roughly $221 million.

Why it mattersThe cause sat outside crypto. A 30-year government bond paying over 5% is real competition for any asset that yields nothing. Push that rate down and the arithmetic changes for everyone weighing risk. That explains how broad the move was, with inflows across nearly every listed fund, XRP and Solana included. Two consecutive days of rising ETF inflows suggest buying that goes beyond short covering. And a 20% run in three days usually hands some of it back once momentum cools.

What's nextThe first enlarged operation is not until 9 September, so the market is trading an announcement rather than executed policy. Watch the 30-year yield as the gauge. If it keeps falling, the story holds. If it climbs back toward 5.3%, the reason this started disappears.

Trump makes a full push for the CLARITY Act at the White House

On 19 August the White House hosted executives from Coinbase, Kraken, Robinhood, Ripple, Chainlink, Gemini, Polymarket and Kalshi, along with venture firms including Andreessen Horowitz and Paradigm. SEC Chairman Paul Atkins and CFTC Chairman Michael Selig attended. Trump praised the industry and urged the Senate to pass the Digital Asset Market Clarity Act. The bill would write into law when a digital asset is a security and when it is a commodity, a line currently drawn by agency interpretation. The House passed it in 2025. In the Senate it has been stuck since July over ethics provisions: seven Democrats rejected the latest draft and want elected officials barred from issuing, endorsing or profiting from digital assets. Majority Leader John Thune filed the motion to proceed. The procedural vote is set for 15 September at 2 p.m.

Why it mattersThe blockage is not a technical argument about token classification. It is about whether elected officials may earn money from digital assets, with the president as the live example. That makes a compromise politically more expensive than it looks. Prediction markets put the bill's odds around 19.5% this month. Markets did respond well to the White House event, though the rally started on Wednesday before Trump spoke.

What's next15 September is a cloture vote and it needs sixty. The number of Democrats crossing over is the only figure that counts that day. If the standoff holds, market structure legislation almost certainly slips past the midterms, leaving the SEC's 18 August proposal as the only federal rulebook actually on paper.

The CFTC is talking about bringing Hyperliquid onshore

At the same event Trump named Hyperliquid directly and said CFTC Chairman Selig is working to bring the platform into the United States in a fully compliant and legal fashion. Hyperliquid is one of the largest venues for perpetual futures and currently does not serve US users. Its HYPE token jumped by double digits, reported somewhere between 11% and 19% intraday, on trading volume that roughly tripled. A day later, on 20 August, the CFTC held the first meeting of its Innovation Advisory Committee, a three-hour session with crypto assets, artificial intelligence and prediction markets on the agenda. Walt Lukken of the Futures Industry Association chairs the committee, and Coinbase, CME and Kalshi were among those at the table.

Why it mattersA president naming a specific DeFi venue from the White House is new. It also shows which route Washington is taking: rather than wait for legislation, build a path in through the CFTC for firms currently outside the perimeter. For European traders the question is what that does to liquidity. A US Hyperliquid bound by CFTC rules will probably look different from the offshore product that generates the volume.

What's nextThere is no application and no timeline yet, only a statement. Watch whether Selig picks the subject up in the committee's follow-up work. And watch the competition: if this path is real, other offshore derivatives venues will move quickly.

Glamsterdam is now running on a public testnet

The Ethereum Foundation's Platåberget testnet transitioned to the Glamsterdam fork on 20 August. Anyone can run a validator or builder on it. The upgrade brings enshrined proposer-builder separation (EIP-7732), block-level access lists (EIP-7928), a gas repricing and larger contract size limits. Unlike the short-lived devnets used for earlier upgrades, Platåberget will stay up for months. The Foundation is explicit about breaking changes: wallets, indexers and gas estimators built on fixed assumptions will fail. A plain ETH transfer no longer always costs 21,000 gas. Mainnet comes only after Sepolia and Hoodi, somewhere in the second half of 2026.

Why it mattersThe protocol is the smallest problem here. The risk sits in the software around it, where fixed numbers have been baked in for years. Anyone building transactions or estimating fees has to measure again. For European firms running payments or tokenisation on Ethereum, that means scheduling a test round, and doing it before the Sepolia fork rather than after.

What's nextThe months on Platåberget exist to find what breaks. Follow the bug reports from client teams. An upgrade that rolls quietly across a testnet tells you little. An upgrade where three wallets show wrong gas prices at once tells you everything about the mainnet timeline.

Maya Protocol halts its chain after a six-bug attack

Maya Protocol brought MAYAChain to a full stop after an attacker chained six software flaws together to fool the network's accounting. The attack was a single transaction carrying 23 messages, which triggered a false theft detection, manipulated a thin liquidity pool and then let 48.87 million CACAO out of the Asgard liquidity module. Co-founder Aalux said on 19 August that the attacker took roughly 20 bitcoin, worth about $1.4 million, plus another $300,000 or so in other assets. Wider damage to the pools ran to an estimated $11 million. CACAO lost close to 90%. The protocol offered the attacker a white-hat bounty in exchange for disclosing the flaw and returning the funds.

Why it mattersNone of the six flaws was fatal on its own. Together they were. That is exactly the kind of risk audits handle badly: they look at components, while the attack lived in the combination. For cross-chain protocols the stakes are higher, because accounting on one network decides what gets paid out on another. And the damage to the pools ran about seven times larger than what the attacker walked away with.

What's nextMaya says it wants a fix in place before swaps reopen. The open question is who absorbs the holes in the pools: liquidity providers, the protocol treasury, or nobody. That answer decides whether liquidity comes back at all.

MiCA review

The European Commission's consultation on the MiCA review closes on 31 August, with questions on staking, lending and borrowing. The transition period ended on 1 July, and ESMA expects unauthorised service providers to hold immediately executable wind-down plans, including transferring clients and assets.

Tokenisation

DTCC has been running limited production trades in tokenised stocks and Treasuries since mid-July, with more than fifty institutions involved including BlackRock, Goldman Sachs, JPMorgan and Bank of America. Full commercial launch is planned for October 2026.

Regulation

SEC consultation

The comment window on Regulation Crypto Assets, the issuance regime the SEC proposed on 18 August, runs sixty days from publication in the Federal Register. Pre-empting state securities registration is the most contested piece in it.

Take

Three things to take away

1. The rally came from the bond market. Not from a law, not from a regulator. An announcement about buying back 30-year government debt pushed yields down and lifted everything sensitive to liquidity. Bitcoin moved as a risk asset, not on a story of its own.
2. CLARITY is stuck on ethics. The Senate dispute is about whether elected officials may profit from digital assets. Technical drafting is not the problem. On 15 September the only thing that counts is whether sixty votes exist.
3. Building continues, and sometimes it costs. Ethereum forked a testnet on Wednesday that will stay up for months precisely to find what breaks. Maya Protocol found that out the hard way: six separate bugs, one transaction, around $11 million in damage.
