30-Year Clears at 5.618%, MOVE Near 100, VIX at 15.4: Desk Notes for Michigan Sentiment Day

Thursday, October 8, finished the week’s coupon supply, and the long end came through it better than it went in. Treasury sold $22 billion of 30-year bonds at a high yield of 5.618%, the highest 30-year auction yield since August 2000, per Barron’s via SquawkNews. After the sale the 10-year fell 4.9 basis points to 5.232% and the 30-year fell 5.5 to 5.606%, per Investrade, a day after the 10-year touched 5.365%. Treasury’s official par curve had the 2-year at 4.75%, down only 2 basis points, per The Financial Current. That is a bull flattener: term premium came out of the long end while the front end, which tracks the Fed path, barely moved.

Stocks split. The S&P 500 fell 0.47% to 7,765.36 and the Nasdaq Composite fell 1.25% to 27,193.34 after the Financial Times reported that OpenAI’s annualized revenue was about $20 billion below earlier figures, while the Dow rose 0.10% to 51,231.64 and the Russell 2000 finished up 0.03%, per Swingfolio. The VIX rose 0.33 to 15.41. Brent crude rose about 4% to roughly $104 on Iranian tanker attacks and Gulf hurricane shut-ins. Early Friday, CNBC had the 10-year flat at 5.24%, the 30-year flat at 5.615%, and the 2-year up about 2 basis points to 4.78%, after President Trump said the U.S. will not strike Iran before next month’s midterm elections.

The 30-year: a record-high yield, an ordinary bid

The auction stopped 31 basis points above September’s 5.308%. Bid-to-cover was 2.54 against a 2.41 six-auction average, indirect bidders took 72.3% against about 69%, and dealers were left with 6.8% against about 10%, per Helious and TFTC. Helious graded it in line and on the screws, meaning it cleared at the when-issued yield with no tail. Barron’s noted that after a 10-year as strong as Wednesday’s, the next 30-year has been weak about three-quarters of the time since 2020, per BMO’s Vail Hartman, so an average result was itself a small relief. Across the week, the 3-year was soft, the 10-year was strong, and the 30-year was average. Buyers are showing up at these yields, not ahead of them.

Claims stay low, and today is about inflation expectations

Initial jobless claims fell 2,000 to 197,000 for the week ended October 3, and continuing claims rose 17,000 to 1.716 million, per the Labor Department release summarized by The Financial Current. That fits the Fed’s year-end hike story in the minutes. At 10:00 a.m. ET today the University of Michigan releases preliminary October sentiment, which FXStreet expects at 47.6 after September’s 48.1. The number that matters for rates is the one-year inflation expectation, last at 4.6%, with the five-year at 3.4%. With Brent above $100, a higher one-year reading is the path that would put the front end back in play before September CPI on October 14.

Calendars, diagonals, butterflies, and parity

Calendars roll into CPI. This week’s weekly expiry is today, so the calendar that sold it and bought the October 16 monthly now has only Michigan left in its short leg. From Monday, the front monthly is the short leg, and it holds CPI on Wednesday. A calendar that sells October 16 and buys a November expiry is short the CPI print, the reverse of the position described here yesterday. Event premium in the short leg collapses after the release, which helps the spread if the index stays near the strike and hurts it if CPI moves the index well away. The debit is still the maximum loss.

Diagonals as the vol gap narrows. The MOVE index closed at 100.70 on Thursday, down from 113.60 on Monday, per Investing.com. Over the same three sessions the VIX went from about 15.5 to 15.41. The MOVE-to-VIX ratio has come down from about 7.3 to about 6.5. Rates vol is cooling while index vol stays put, so a diagonal’s vega-long back leg is less cheap relative to the bond market than it was on Monday. It is still inexpensive in absolute terms, with the VIX below its 200-day average near 18 per the Cboe VIX quote page. In rates proxies such as TLT, the supply events that justified owning back-month vol are now behind us, and CPI becomes the next one.

Butterflies and dispersion. The Nasdaq fell 1.25% while the Dow rose, semiconductors lost about 3.5%, and energy and staples each rose 2% to 3%, while the VIX moved a third of a point. Single-name AI vol carried the stress and index vol did not. That is the setting where a long index butterfly behaves as designed: the loss is capped at the debit, and the body belongs at the option-implied forward for its expiry, not at spot. A single-name fly in Broadcom, Micron, or Oracle needs wider wings, because those names moved 4% to 5.5% in a session in which the S&P moved under half a percent.

Parity when the front end will not move. The long end fell 5 to 6 basis points on Thursday, but the 2-year fell only 2, and the 2-year is the rate that matters for put-call parity on short-dated index options. At 4.75% on the S&P at 7,765, a year of carry is roughly 369 points before dividends. A bull flattener does almost nothing to that carry term, so a conversion or reversal priced off the cash index has the same financing hurdle it had before the auction. The term moves when the front end moves, on CPI or a hawkish inflation-expectations reading.

Desk rule for today: read the Michigan one-year inflation expectation at 10:00 before the headline sentiment number. The long end has had its supply tests this week; the front end is waiting for inflation data.
