Yields Climb, VIX Eases to 18.44: Desk Notes for Housing Starts and the 20-Year Auction

Tuesday, October 20, 2026, opens after a split Monday. Tech led a partial rebound from Friday’s chip selloff: the Nasdaq Composite rose 1.11% to 26,430.89 and the S&P 500 gained 0.41% to 7,690.73, while the Dow slipped 0.07% to 51,966.03. The Wall Street Journal reported that some of last week’s hardest-hit chip names bounced most, with Intel up 2.4% after a 14% drop last week, Micron up 3%, Marvell up 4%, and the PHLX Semiconductor index up 1.6%. Equity volatility eased while Treasury yields climbed, and builder sentiment fell to its lowest reading since 2012.

The VIX closed at 18.44, down 1.55 points or 7.75%, after trading between 17.39 and 18.93. Dow Jones Market Data had the 10-year yield up 3.8 basis points to 5.135% at the 3 p.m. ET Tradeweb close, its largest one-day gain since October 2 and 17.5 basis points below its 52-week high of 5.310% from October 5. Rates volatility barely moved: the MOVE index closed at 101.30, up 0.20, though it touched 105.23 intraday. The WSJ had Brent futures down 0.3% at $109.55 a barrel.

What the late tape said

• Equity vol and rates moved in opposite directions. The VIX gave back most of Friday’s jump while yields rose across the curve. Treasury’s daily par yield curve put the 2-year at 4.77% (from 4.74% Friday), the 10-year at 5.15% (from 5.09%), the 20-year at 5.53%, and the 30-year at 5.48%. That widened the 2s/10s gap on Treasury’s curve to 38 basis points from 35.
• Real yields led the move. Treasury’s real yield curve had the 10-year TIPS yield at 2.80%, up from 2.74% Friday, matching the 6-basis-point rise in the nominal 10-year on Treasury’s curve.
• The 20-year still sits above the 30-year. On Treasury’s curve the 20-year yielded 5 basis points more than the 30-year, the hump going into Wednesday’s 20-year reopening.
• Builders hit a 14-year low. The NAHB/Wells Fargo Housing Market Index fell three points to 29 in October, its lowest since June 2012. Buyer traffic dropped five points to 18, and 43% of builders cut prices, the highest share in NAHB’s 2020–2026 tracking. NAHB said mortgage rates have climbed well above 7% in recent weeks.
• Abroad, a weaker close. The WSJ reported European stocks and French bonds slumped Monday; TheCloseReport had the DAX down 1.18% and the FTSE 100 down 1.08%.

Today’s calendar

• 8:30 a.m. ET: September housing starts and building permits, per the week-ahead calendars from StockHub and Bent Pine Capital.
• Treasury: a 6-week bill auction today and the $13 billion 20-year bond reopening Wednesday at 1 p.m. ET, then a 5-year TIPS auction Thursday, per Treasury’s tentative auction schedule and Investrade’s weekly calendar.
• Earnings before the open: GE Aerospace, General Motors, RTX, Northrop Grumman, and 3M. After the close: Netflix, Intuitive Surgical, Capital One, United Airlines, and Chubb, per StockHub.
• Later this week: Meta, Tesla, IBM, Lam Research, and Texas Instruments after Wednesday’s close; jobless claims and the leading index Thursday; flash PMIs and final October Michigan sentiment Friday.
• Fed: The FOMC meets October 27–28, with the decision at 2 p.m. ET on the 28th. Officials are in the blackout period from October 17 through October 29, so no scheduled Fed speakers this week.

Calendars, diagonals, butterflies, and parity

Calendars after a vol giveback. A 7.75% drop in the VIX in one session mostly comes out of the front of the term structure, which is where a calendar’s short leg lives. Less near-dated premium means a calendar opened today collects less for the same strike than one opened Friday, but the short leg also carries less event risk than it did into the weekend. The calendar debit is still the maximum loss. Single-name calendars across Netflix tonight and Tesla and Meta on Wednesday put the earnings premium in the front expiry, and the implied volatility crush after each report is the event the structure is built around.

Diagonals spanning the Fed. A diagonal whose long back month runs past October 28 owns the Fed decision, while its short front leg may expire before it. With yields rising and equity vol falling on the same day, the back-month leg’s implied volatility depends on whether rates or equities set the tone into the meeting. Size the debit as the loss you accept if the short strike is challenged and the long leg’s implied volatility then falls once the Fed is out.

Butterflies through earnings and the 20-year. A long index butterfly into Friday is a defined-risk way to study a range view across Netflix, the 20-year auction, and the Meta and Tesla reports. Center the body on the option-implied forward rather than Monday’s close, set the wings from the market’s own implied move, and keep the debit as the maximum loss.

Synthetics and parity vs. short rates. Put-call parity ties a synthetic long (long call, short put at the same strike and expiry) to the underlying plus financing. The 2-year rose 3 basis points to 4.77% on Treasury’s curve and 3-month bills sat at 4.27%, so the carry input for short-dated conversions and reversals edged up. Recheck parity pricing against live short rates and expected dividends rather than last week’s levels.

Desk rule for today: note that the equity-vol and rates-vol stories split again, watch whether housing starts confirm the builders’ gloom with mortgage rates above 7%, and treat Netflix tonight and the 20-year auction tomorrow as separate events inside the window before the Fed.
