The long end caught a break.

Brent crude neared $112 a barrel on Tuesday morning and then gave it back, finishing down 0.7% at $108.79 by AP's account of the session. The bond market took the cue at the long end. Treasury's 3:30 p.m. ET par curve put the 30-year at 5.42%, down six basis points from Monday, and the 10-year at 5.12%, down three. The 2-year went the other way, up two basis points to 4.79%, and the 5-year sat at 4.94% both days. The gap between 2- and 10-year yields narrowed to 33 basis points from 38.

The morning's data gave the long end a second reason. The Census Bureau said housing starts ran at a 1,221,000 annual rate in September, 5.2% below August's revised 1,288,000 and 7.4% below a year earlier. The monthly change sits inside the release's own ±11.8% margin, so it reads as soft rather than as a confirmed drop. Building permits slipped 0.2% to a 1,400,000 rate.

The front end has a different anchor. The Federal Open Market Committee raised its target range a quarter point to 3.75% to 4% on Sept. 16, by a 12-0 vote, saying inflation remains elevated and that the move should bring it back to 2% sooner. The September consumer price index, published Oct. 14, shows why the two ends of the curve can disagree: all items up 3.7% over 12 months, energy up 20.4%, everything except food and energy up 2.6%. The next meeting is Oct. 27-28, and participants have been in their pre-meeting blackout since Oct. 17. With the 1-month bill at 4.10% and the 2-year at 4.79%, the front end is still carrying some tightening the Committee has not delivered. That is this issue's reading of the curve, not anything the Fed has said.

Overnight, oil took some of Tuesday back. Brent was up 1.5% at $110.40 a barrel early Wednesday and U.S. crude up 1.4% at $99.24, AP reported at 2:54 a.m. ET; the month's range is $97 to $112. On Oct. 18 Iran's Revolutionary Guard said two tankers had caught fire after hitting mines in the Strait of Hormuz, where Iran requires ships to seek its authorisation before transiting, Al Jazeera and AFP reported. Asia was mixed. Seoul's Kospi rose 3.3% to 5,735.66 after a 3.7% drop on Tuesday, when the AI company Elice fell 32% on its first day of trading. The Nikkei 225 closed up 0.9% at 64,621.24. The euro slipped to $1.1226 from $1.1239.

Today tests whether Tuesday's buyers of duration were real. Treasury auctions $13 billion of the 20-year bond, a reopening announced Oct. 15 that settles Friday, Oct. 23; Thursday brings $26 billion of 5-year notes. The 20-year closed Tuesday at 5.47%, five basis points above the 30-year, so the sector is already the cheap corner of the long end. The Energy Information Administration's weekly inventory report lands at 10:30 a.m. ET. The conditional, in this issue's reading: if Brent holds above $110 into the auction, the six basis points the 30-year gained on Tuesday are the first thing at risk. If the auction clears without a tail, the flattening has a buyer behind it.
