The 30-Year Treasury Yield Just Hit Its Highest Level Since 2007

The 30-Year Treasury Yield Just Hit Its Highest Level Since 2007

The 30 year Treasury yield topped 5.31 percent on Monday and settled near 5.29, the highest it has been since 2007. It rose about 3 basis points on the day. Long dated US government debt is now the most expensive it has been to issue in nineteen years, and the Treasury has a great deal of it left to sell.

The long end has been coming apart slowly all year rather than in one dramatic session. Inflation has run above the Fed's 2 percent target for five straight years and sits at 3.4 percent, which makes lending to anyone for three decades an act of some optimism. Add a national debt nobody in Washington is seriously trying to shrink. The buyers who used to absorb this paper without asking questions have thinned out, and nothing has arrived to replace them.

Supply is the immediate problem. A heavy calendar of long dated issuance is landing at the same moment as a wave of corporate borrowing to fund AI infrastructure, and both are competing for the same limited pool of duration buyers. The most recent 10 year auction cleared at the highest financing cost since 2007. Meanwhile the 2 year yield has fallen 12 basis points this month, because the front end still believes the Fed is close to done. The curve is steepening from the wrong end.

Equities noticed. The S&P 500 closed Monday at 7,744.97, down 0.52 percent, with the damage concentrated in credit sensitive financials and the largest technology names. Microsoft fell 3 percent and Meta 3.5 percent. Gold rose 1.08 percent to 4,422.81 dollars an ounce as the inflation hedge did its job. Brent at 91.08 dollars is feeding the same argument, and the long end can feel a rising oil price faster than almost anything else.

The FOMC minutes arrive Wednesday and will show how divided the July hold actually was, though they describe a meeting that happened before crude went to 91. Anshul Pradhan at Barclays has been telling clients not to fade the long end selloff and says he still would not. He listed what would change his mind: a fiscal surprise, lighter AI issuance, a shift in Treasury strategy, or soft data that keeps arriving. None of those four looks imminent this week.

A 5.3 percent thirty year reprices mortgages, corporate debt and every long duration asset anyone owns. It also quietly raises the government's own interest bill for the next three decades, one auction at a time. That second part never shows up in a daily close.
