On Tuesday the interest rate the US government pays to borrow for thirty years hit its highest since 2007. On Wednesday afternoon the Treasury said it will at least double what it can buy back in each operation for bonds maturing in ten to thirty years, from $2 billion to at least $4 billion, starting September 9.

That is a plumbing notice. Traders read it as something closer to a promise, that Washington will step in when the cost of long-term government borrowing starts to hurt.

Bitcoin rose about 6% by mid-afternoon. Ether did better, up 18%. Gold and silver rose with it and the dollar softened. The thirty-year yield fell to 5.19%, its biggest one-day drop since October.

Traders call this the debasement trade, the plain habit of buying scarce things when you think governments would rather live with inflation than live with expensive borrowing.

Later that afternoon, at a White House gathering, Trump said a "sizable" government bitcoin purchase had "been talked about." Bitcoin cleared $70,000 shortly after, for the first time since June 2.

The move was thinner than it looks. The Defiant counted about $1.7 billion of leveraged bets closed out in the session, and about nine in ten of them were bets against the market. That is people who had bet on a fall being forced to buy back in. Glassnode, writing before all this, had already flagged the same absence. Americans buying on Coinbase are still paying less than the rest of the world, which is what you see when US buyers stay home.

Plenty of people online called it money printing. It was not. The Treasury is buying back its own existing debt while it keeps issuing more elsewhere.

The test is this week. Before Wednesday, bitcoin had spent two weeks between $64,000 and $65,000, and nothing yet says the Americans who sat that out have changed their minds.

Base App is Coinbase's consumer app, the one it wants to be an everything app. Yesterday it went live with perpetual futures, bets on a price with no expiry. Hyperliquid matches and settles them itself, on-chain. More than 290 markets sit on it, covering crypto, tokenized stocks and commodities. You can borrow fifty times what you put in.

Americans cannot use it. Neither can anyone in the UK or Canada, or anywhere that caps borrowed money in crypto.

That may not hold. At the White House on Wednesday, Trump said the Commodity Futures Trading Commission is working to bring Hyperliquid into the US in a fully compliant and legal way, and credited chairman Michael Selig with leading it.

Coinbase's head of engineering told Decrypt this kind of trading is about 75% of all crypto volume. If the Washington route works, it lands in an app plenty of Americans already carry.

Send money home with a stablecoin and the chain fee is about 0.4%. That number has done a lot of work in a lot of pitch decks.

The Bank of Italy added up everything else. Getting cash into the coin at one end, funding the exchange, then getting cash out at the other end takes the all-in cost to nearly 9%. Traditional remittance channels charge roughly the same. The study's conclusion is that stablecoin transfers still lean heavily on ordinary banking rails.

The chain fee was never the expensive part. The cost sits at the two ends, where cash turns into the coin and back again, and those ends still run on the banks.

If the fee is why you hold on-chain dollars, the number to check is what your app charges you going in and coming out.
