The Treasury Doubled Its Long-Bond Buybacks, and the Long End Sold Off Again the Next Day

One market set the terms this week. On Tuesday the 30-year Treasury yield reached 5.31 percent, the highest since 2007, days after federal debt passed $40 trillion. On Wednesday Treasury Secretary Scott Bessent doubled the maximum size of each long-dated repurchase operation, from $2 billion to at least $4 billion, and the 30-year retreated from 5.34 percent. The relief lasted one session. By Thursday the ten-year was back at 4.71 percent. Buybacks change who holds the debt, not how much of it there is, and Japan enters the same test with a sharply higher budget request.

Everything else repriced off that. Gold held above $4,500 and silver topped $68, against roughly $4,390 and $64 at the start of the week. Bitcoin, below $63,000 on Saturday, traded above $75,000 by Friday after traders betting on further declines lost about $3.8 billion over two days. That is a positioning unwind driven by the yield curve, not a change in what anyone thinks the asset is worth.

The second development was the Gulf. Brent settled near $94 after the United Arab Emirates suspended all trade with Iran and Bessent said new sanctions would "collapse this regime," urging China to comply. Sixty-seven commercial vessels have been redirected in five weeks of blockade, and only three ships crossed Hormuz last Sunday against roughly 130 a day before the war. Two more routes narrowed in the same week, as the Panama Canal cut daily transits for drought and pirates seized an arms ship off Somalia.

Among tracked theses, the largest move was authorized-path exploits, up 37 points. The week's crypto losses again came from components that worked as specified: five valid validator signatures at AFX Trade, and about $115 million drained from Coldcard wallets through a 2021 firmware build error that cut key strength to as little as 40 bits. Proving-system soundness rose 28 points after Aztec disclosed a second critical flaw, this one on its live network. Market-structure stalling rose 24 points, then partly resolved: the Securities and Exchange Commission cancelled its rulemaking meeting, proposed Regulation Crypto Assets four days later, and the Commodity Futures Trading Commission said it will write rules alone if the Senate bill fails on September 15.

One thesis had a bad week. Renewed Federal Reserve tightening as the driver of market stress weakened again. Inflation slowed to 3.4 percent and long yields rose anyway. Supply, not policy expectations, is setting the long end. Quantum risk fell eight points after Ethereum researchers dropped the Poseidon hash, judging conventional hashes fast enough. Ukraine's refinery campaign weakened while strikes inside Russia strengthened by 26 points, as the exchange moved to cities: at least 12 dead in Kyiv and 620 drones toward the Moscow region.

Next week turns on whether the long end holds without another Treasury operation, and on what the promised Iran sanctions actually name.
