Bond Market Shrugs Off Bessent as Yields Rebound

Scott Bessent told CNBC the U.S. deficit has "a very good chance" of having peaked and that a Treasury buyback could top $4 billion. The bond market erased the whole intervention within hours, sending the S&P 500 down 0.9%.

Bessent, Treasury secretary and one of Trump's most trusted economic hands, made the case on two fronts Thursday. On Iran, he said the U.S. likely will not need to restart large-scale combat, hours after Trump declared "economic D-day" on Tehran. On the domestic side, he argued the monthly budget deficit – which hit $432 billion in July, its highest in more than half a decade – has turned a corner.

None of it stuck. Yields rebounded, wiped out the decline Bessent's buyback announcement had triggered, and pulled equities lower. Futures were little changed early Friday, a sign traders are still sorting out whether the sell-off was a one-day scare or the start of a real showdown between the Treasury and the bond market.

Bessent's Iran playbook is "maximum economic pressure" – sanctions plus the existing U.S. naval blockade in the Gulf of Oman – rather than fresh strikes. He'll spell out the details at a news conference Monday. Trump claimed on Truth Social that Iran's economy is already collapsing and the regime is "hanging by a thread." A former adviser to Iran's central bank pushed back, arguing Tehran's economy is not as close to collapse as Washington claims, but that the UAE's decision to sever trade ties could still deal a serious blow.

Japan's historic yen intervention may have had an unintended consequence: giving some investors a better opportunity to double down on the carry trade. Japanese investors net bought more than 5 trillion yen of foreign equities and long-term bonds over the two weeks ended Aug. 15, compared with net selling of over 300 billion yen in the prior two weeks, Ministry of Finance data showed. The purchases suggest investors took advantage of the yen's sharp rally following last month's joint U.S.-Japan currency intervention to snap up overseas assets at more favorable exchange rates, market watchers said.
