final rationale
Mean of 2 draws (0.09, 0.12). (0) The condition is not met. Treasury's own par yield CSV shows an October 10Y high of 5.31% on Oct 5 and a latest print of 5.21% on Oct 13, so nothing has resolved. To resolve YES, a daily par close of at least 5.50% has to print by Oct 30. (a) About 13 business days remain (Oct 14–30), since Oct 31 is a Saturday. (b) If nothing changes, the 10Y stays in its 5.19–5.31% October range and the market resolves NO. Realized October daily moves have been only about 3–5bp, so a 29bp barrier is roughly 2 standard deviations away on realized vol. (c) NO path: CPI and PPI land near consensus, with core around 0.2%. Oil stays contained after the energy ceasefire, and the Fed holds on Oct 28 (about 78–80% priced). Strong auction demand and asset managers buying near 5.2–5.3% cap yields. (d) YES path: a hot core CPI or PPI combines with a renewed Hormuz or Iran oil spike. That revives October hike pricing, and a 15bp-plus day like Sep 23 strings together into a new multi-decade high above 5.50% before month end. The Kalshi anchor is 12% (bid 9 / ask 18). Polymarket's related "5.5% before 2027" at 33% covers a much longer window, so it is consistent with a low single-month probability. Fat-tailed jump risk in this regime justifies more than a pure random-walk estimate, but I shade slightly below the market's 12%.

Planner reasoning
This is a question about whether the 10Y Treasury yield reaches a threshold before Oct 31, so the main inputs are the current yield level and the ~2.5 weeks left. FRED DGS10 gives recent daily values and volatility, and the Treasury par yield curve page is the resolution source and shows whether 5.50% has already printed in October. Kalshi's own market and sibling strike markets give price anchors, and Polymarket supplies a cross-check from a different crowd.

That would revive October-hike pricing before the Oct 28 FOMC and push the 10Y close up about 28bp from about 5.22%. It would need a 12-session run through a multi-decade high, and nothing in the data so far shows it. - no case: A 5.50% par close needs about +31bp in 14 business days, to a level the 10Y has not closed at in the data cited here, with the Fed, Treasury, big asset managers and the oil trend all leaning against it. The status quo, a 5.2–5.3% range, resolves NO.

- [2026-10-13] The Treasury par yield for the 10Y was 5.21%, down 3bp, in the latest official print I could see (via a site that mirrors Treasury data). The gap to 5.50% is 29bp. The 30Y was 5.56% and the 2Y 4.79%. https://stockmarketwatch.com/bonds/10-year-treasury-yield - [2026-10-01 to 2026-10-13] Daily par 10Y so far in the October window: Oct 1 5.24, Oct 2 5.28, Oct 5 5.31, Oct 6 5.27, Oct 7 5.28, Oct 8 5.22, Oct 9 5.24, Oct 13 5.21. The window high is 5.31%, and no day has reached 5.50%. https://stockmarketwatch.com/bonds/10-year-treasury-yield - [2026-10-05 to 2026-10-07] Intraday peaks were the highest since 2002. The 10Y hit 5.349% on Oct 5 (CNBC) and about 5.35–5.365% on Oct 7 (Investing.com). Those intraday highs were still about 14bp below 5.50%, and intraday values do not count for this contract. https://www.cnbc.com/2026/10/05/treasury-yields-bonds-fed-rates.html - [2026-10-07] The 10Y yield backed off after a solid $39B 10-year auction (bid-to-cover 2.77) and the 30Y auction on Oct 8. FOMC minutes showed officials expect further hikes. https://www.cnbc.com/2026/10/07/treasury-yields-auction-fomc-minutes.html - [2026-10-13] The 10Y fell to about 5.215% intraday as energy prices stabilized. Markets reopened after the Columbus Day closure on Oct 12 (no Treasury par yield for that day). Brent was about $105.7 and WTI about $94. The fall in oil followed a US-brokered Russia–Ukraine "energy ceasefire". https://www.cnbc.com/2026/10/13/us-treasurys-bonds-yields.html - [2026-10-14] A live quote showed the 10Y around 5.22–5.23%, roughly unchanged on the day, before or around the CPI release. Trading Economics' quarter-end model forecast is 5.18%. https://tradingeconomics.com/united-states/government-bond-yield - [2026-10-14] September CPI is released at 8:30am ET today. Consensus is headline 3.6–3.7% y/y (August 3.4%), m/m about 0.6%, core 2.5% y/y.

The Fed hiked 25bp (12–0) on Sep 16 to 3.75–4.00%, its first hike in three years under Chair Warsh. Williams called another hike by year-end "a reasonable expectation". https://fedratecalc.com/fomc-meeting-schedule/ and https://www.crestwoodadvisors.com/october-2026-economic-and-market-update-higher-and-higher-bond-yields-rise-to-levels-not-seen-in-nearly-two-decades/ - [2026-09-30] The 10Y closed September at 5.29%, up 54bp since Aug 31. The September 29 session high was 5.27%, and the Sep 15 intraday high of 5.04% was then the highest since 2007. The 52-week closing high is 5.31% (Oct 5). https://stockmarketwatch.com/bonds/reports/october-2026 and https://www.macrotrends.net/2016/10-year-treasury-bond-rate-yield-chart - [2026-10-02] The September jobs report was weak, which eased the Fed-hike worry. https://www.cnbc.com/2026/10/05/treasury-yields-bonds-fed-rates.html - [2026-10-xx] Nuveen forecasts the 10Y at 4.95% for year-end 2026. The 10Y TIPS real yield was 2.91% and the 10Y breakeven 2.33% on Oct 9. https://www.nuveen.com/en-us/insights/fixed-income/fixed-income-weekly-commentary and https://theoptionsclub.substack.com/p/yields-ease-expectations-climb-september BOTTOM LINE: The Treasury par 10Y is about 5.21–5.23%, roughly 27–29bp below 5.50%, and its October peak close is 5.31%, with no day reaching 5.50%. The remaining catalysts are today's CPI, PPI and retail sales, and the Oct 28 FOMC, with roughly 12 trading days left in the window. NOT FOUND: The actual September CPI result and the market reaction on Oct 14. Treasury's official Oct 14 par yield, since it is published after the close. The Treasury page I fetched had the October table truncated, so the daily figures above come from a mirror of Treasury data, cross-checked against the Fed H.15/FRED values for Oct 5–9.
report: base rate
- [2026-10-13] The 10Y was about 5.215% intraday. Treasury markets reopened after the Columbus Day closure, and yields fell as energy prices stabilised. The 30Y was 5.564% and the 2Y 4.791%. September CPI, due Oct 14, was expected at 3.7% year on year, up from 3.4%. https://www.cnbc.com/2026/10/13/us-treasurys-bonds-yields.html - [2026-10-14] Trading Economics shows 5.22%. Its Q4 model forecast is 5.18% and its 12-month forecast is 4.97%. The headline was "retreat from 24-year highs". https://tradingeconomics.com/united-states/government-bond-yield - [2026-10-09] The daily par yields (Fed H.15 series and vendors quoting Treasury data) were: Oct 1 5.24, Oct 2 5.28, Oct 5 5.31, Oct 6 5.27, Oct 7 5.28, Oct 8 5.22, Oct 9 5.24. The Oct 5 close of 5.31% is the October high so far and the 52-week high. The Sep 30 close was 5.29%. Every Oct close so far is 19 to 28 bp below the 5.50% threshold. https://fred.stlouisfed.org/series/dgs10 and https://stockmarketwatch.com/bonds/10-year-treasury-yield - [2026-10-13] Investing.com shows an intraday peak of 5.365% on Oct 7 and a 52-week range top of 5.365%. Intraday values do not count for this contract. https://www.investing.com/rates-bonds/u.s.-10-year-bond-yield-historical-data - [2026-10-13] The Oct 13 close was about 5.19%. Needed move to reach 5.50% is roughly +30 bp. That is about 3 standard deviations of daily moves over about 13 trading days (Oct 14–30), if daily vol is roughly 5–7 bp. This is my own arithmetic, not a sourced figure. https://www.investing.com/rates-bonds/u.s.-10-year-bond-yield-historical-data - [2026-10-07] A survey of nearly 60 strategists (Oct 5–7) gave median 10Y forecasts of 5.00% at year-end, 4.90% in 6 months and 4.75% in 12 months. Strategists had misjudged direction for nine straight months. Q3 was the largest quarterly rise since 1994. Drivers cited were the US-Israel war with Iran, global central-bank hikes, AI-related borrowing and Treasury supply. https://www.tokenpost.com/news/investing/27403 - [2026-10-09] Strategist views: JPMorgan sees 5.05% by year-end. Morgan Stanley and Deutsche Bank see 4.8%. Barclays sees 5.0%. Morgan Stanley's bear case is 5.25%, which it says spot has already reached. The date of this page is unverified. https://archr.com/finance/us-strategists-on-bond-yields/ - [2026-10-13] Northern Trust's chief economist expects the 10Y near 5.2% through 2028. Some economists warn of 6%. The CBO (Feb) had projected the 10Y would stay below 4.3%. https://en.sedaily.com/international/2026/10/13/us-10-year-yield-could-hit-6-percent-economists-warn - [2026-10-08] The 10Y was 5.22% on Oct 8, up from 4.13% a year earlier. The 2026 average is 4.49%. The 52-week range is 3.97% to 5.31%. The 1981 peak was 15.84%. The post-2007 high for this series is below 5.50% (the Oct 2023 peak was about 5.0%; in 2007 it peaked around 5.3%). https://www.macrotrends.net/2016/10-year-treasury-bond-rate-yield-chart - [2026-09-08] The 10Y started 2026 at 4.19%, closed at 4.80% on Sep 8 and had a 2026 low of 3.97% on Feb 27. The yield then rose about 50 bp in 5 weeks (Sep 8 to Oct 5). That is a fast run, but the pace has stalled since Sep 30. https://macroodds.com/blog/10-year-treasury-yield-forecast-2026 - [2026-09-30] The Sep 30 curve was 10Y 5.29%, 2Y 4.88%, 30Y 5.64%. The fed funds target was 3.75–4.00%. Rate-hike odds were a "coin flip" for the September FOMC per a Sep 8 post. https://stockmarketwatch.com/bonds/reports/october-2026 - [2026-10-13] Base rate: a close at or above 5.50% would be the highest 10Y close since before 2007, outside the whole post-2007 sample. Historically, a +30 bp move in about 13 trading days is uncommon, but it has happened in 2026 (Sep 8 to Oct 5 was +50 bp over 20 trading days). https://www.macrotrends.net/2016/10-year-treasury-bond-rate-yield-chart BOTTOM LINE: The 10Y has stayed in a 5.19–5.31% band for the first two weeks of October and needs about +30 bp to a new multi-decade high. Surveyed forecasters, the Trading Economics model and a falling-oil tape point to flat or lower yields, while upside tail risk from the CPI print, oil and the war persists. NOT FOUND: Treasury's own October table values (the page text was truncated); the Oct 14 CPI result; any options-implied or fed funds futures distribution for the 10Y; another venue's 5.50% market.
report: yes case
YES means: the Treasury Daily Par Yield Curve 10-year rate is published at 5.50% or higher for at least one business day from Oct 1 to Oct 31, 2026. Intraday values do not count. - [2026-09-24] The September sell-off was fast and sold on bad auctions. Deutsche Bank's Jim Reid called the Sep 23 move the biggest daily jump since April 2025. A weak $70bn 5-year auction cleared at 5.03%, 3.1bp above the pre-sale yield. That shows 10Y can move 15bp or more in one session when supply and Fed-hike news coincide. https://fortune.com/2026/09/24/kevin-warsh-fed-rate-hike-hawkish-iran-bonds/ - [2026-09-24] The oil/Fed mechanism is the single most likely path to YES. Brent touched $108 on Sep 24 as US–Iran talks stalled. BofA still calls for hikes in October and December. Macquarie's Wizman said the Fed would not "look through" energy-driven inflation. A repeat of that setup, with an oil spike plus a hot print, could push yields up. The 5.50% close would need about +28bp from the Oct 13 close. https://fortune.com/2026/09/24/kevin-warsh-fed-rate-hike-hawkish-iran-bonds/ - [2026-10-13] The market was not priced for a dovish turn. Fed futures put the Oct 28 hike at 23% (up from 21.8% a week earlier). Kalshi and Polymarket put a December hike at roughly 75–77% and a hike in 2026 at about 80%. A hot CPI or PPI could move the October hike odds from about 23% toward the 70–75% seen on Sep 23. That would lift the 2Y and likely the 10Y. https://www.investing.com/central-banks/fed-rate-monitor and https://defirate.com/odds/fed-decision/ - [2026-10-13] Mortgage and credit stress has not yet forced a rally. The 30-year mortgage rate hit 7.4% (seven straight weekly rises). Schwab noted IPOs postponed on tighter conditions. Yields fell Oct 13 only because Waller said yields were curbing demand, and that same dip is a sign of how fragile the pullback is. The high-yield spread to the 10Y was 315bp, up from about 260bp in September. If a spread widening came from yields rising, that would favour YES. https://www.schwab.com/learn/story/stock-market-update-open - [2026-10-09] The curve is steep at the long end. The 30Y was 5.60% and the 5Y 5.02% on Oct 9 (10Y 5.24%). The 10Y real yield was 2.91%. Breakevens (2.33%) are low relative to headline inflation of 3.4–3.7%. If breakevens catch up with CPI, the 10Y would rise even with no change in real yields. A +17bp breakeven move would reach 5.50% from 5.24%. https://theoptionsclub.substack.com/p/yields-ease-expectations-climb-september - [2026-10-08] Fiscal supply is large. Treasury projects $628bn of privately held net marketable borrowing for Oct–Dec. Coupon sizes were held (10Y $39B) and the refunding statement says they stay at least several quarters. The next refunding is Nov 4, after the window. Any change to guidance would not hit until after Oct 31. So supply can add pressure only via bills or auction tails. https://economyglobal.com/news/u-s-treasury-to-auction-119-billion-in-3-10-and-30-year-debt-over-three-days-starting-october-6/ - [2026-10-14] A hot September CPI is the key near-term trigger. Consensus is headline +0.6% m/m, 3.7% y/y, core +0.2%. TradingKey says core at 0.3% or higher would revive hike bets. The August core print had beaten estimates and sent yields up sharply (TD, Sep 14). The 10Y is about 5.19–5.23%. https://www.tradingkey.com/analysis/economic/indicators/262213230-us-september-cpi-outlook-inflation-us-stocks-dollar-gold-reaction-tradingkey and https://economics.td.com/us-cpi - [2026-09-14] The trend since the war began is a +100bp rise in about six and a half months (Fortune). Fortune also noted tanker traffic through Hormuz remains well below pre-war levels and US reserves are at 40-year lows. That means an oil spike can recur. The Oct 13 Russia–Ukraine "energy ceasefire" does not address Hormuz. https://fortune.com/2026/09/14/oil-prices-bond-yields-debt-iran-war/ - [2026-10-05] The 10Y has been repeatedly wrong-footed by forecasters. The consensus of strategists had year-end at 5.00%, but spot already passed that in September. Misses have run to the upside. The 5.31% close on Oct 5 shows a close above 5.30% has already happened; the move needed is +19bp from that high. (Own arithmetic.) https://www.tokenpost.com/news/investing/27403 BOTTOM LINE: The most plausible YES path is a hot CPI/PPI plus a renewed oil spike (Hormuz, failed US–Iran talks). That would revive October-hike pricing before the Oct 28 FOMC and push the 10Y close up about 28bp from about 5.22%. It would need a 12-session run through a multi-decade high, and nothing in the data so far shows it. NOT FOUND: The actual Sep CPI result and the Oct 14 market reaction. Treasury's own Oct 14 par yield. Any options-implied distribution for the 10Y. Any other venue's 5.50% market.
report: no case
YES means: the Treasury Daily Par Yield Curve 10-year rate is published at 5.50% or higher for any business day from Oct 1 to Oct 31, 2026. - [2026-10-13] The Schwab market update showed the 10Y at 5.19%, down 5bp. Schwab said Fed Governor Waller argued that higher yields are curbing demand in rate-sensitive sectors, which "implies yields are doing some of the Fed's job." That is a dovish brake on the Fed-hike channel. https://www.schwab.com/learn/story/stock-market-update-open - [2026-10-14] The 5.50% target needs about +31bp from 5.19%. Only the close counts, and Treasury publishes it for each business day. Remaining publishable days are Oct 14–31, which is 14 business days. Oct 31 is a Saturday, so the last print is Friday Oct 30. The Columbus Day holiday on Oct 12 is already past, so no holiday gap helps. Dates are from the Treasury rules; the arithmetic is mine. https://www.cnbc.com/2026/10/13/us-treasurys-bonds-yields.html - [2026-10-14] The Oct 28 FOMC hike odds are low: about 20% on Kalshi and Polymarket, down 4 points in a week, per defirate. Hike odds fell from 51% to about 22% in the week to Oct 7 (CME), after a September payrolls gain of only 29,000 and unemployment of 4.2%. The Fed's marginal tightening impulse is weakening. https://www.investing.com/analysis/fed-october-ratehike-odds-slide-below-22-ahead-of-minutes-200689107 - [2026-10-13] Oct 28 odds (Oct 13): hold 78–81% across futures, Kalshi and Polymarket. Even a hike is mostly priced for December, at 75% for Dec 9. A hold is the base case and the market favorite has won all 14 recent Fed decisions, so a hawkish surprise at the meeting is unlikely. https://predictionmarketspicks.com/tools/fed-rate-tracker - [2026-10-13] Bank of America's fund manager survey says investors wait for a ~6% 10Y before shifting from stocks to bonds. Only 12% set their trigger at 5.5%, and 19% say yields are already there. Equity-versus-bond valuation therefore makes the 5.2–5.5% zone a buying area for some. Polymarket gives about 7% for a 6% 10Y by year-end. That figure was in the search snippet; the page itself returned 403. https://benzinga.com/markets/bonds/26/10/62323584/6-percent-treasury-yield-iceberg-warning-fund-managers-stocks-bonds - [2026-10-13] BlackRock cut US stocks to neutral and upgraded Treasuries, saying the 160bp of Fed tightening priced since January is overdone. It sees a 75bp cushion before 12-month Treasury total returns turn negative. It says the oil/Iran war is the swing factor. Large asset managers are buying the dip rather than selling. https://investinglive.com/stocks/blackrock-cuts-us-stocks-to-neutral-and-buys-treasuries-as-10-year-yield-nears-5-25/ - [2026-10-08] The 10Y auction was a strong one. Indirect bidders took 80.3% against an average of 72.4%, and dealers took only 2.5% against a 9.4% mean. That points to real end-investor demand at about 5.3%, the highest auction yield since 2000. https://en.mercopress.com/2026/10/12/yields-on-key-us-treasury-bonds-reached-new-highs-but-for-the-10-year-demand-was-especially-strong - [2026-08-19] Treasury showed it will lean against long-end stress. It doubled long-end buybacks to at least $4B per operation, through Nov 4. After that announcement the 10Y fell 6bp. A 20Y–30Y buyback is scheduled for Oct 26–27, and the 10Y–20Y one for Nov 3. The Nov 4 refunding falls after the window, and refunding auction sizes are expected unchanged for "several quarters." No scheduled supply shock lands before Oct 31. https://home.treasury.gov/news/press-releases/sb0607 - [2026-10-13] The 52-week range topped out at a 5.31% par close (Oct 5), against 5.36% intraday. The peak, at ~5.36% intraday, followed the Sep 8–Oct 5 surge. That surge stalled, and yields have since retreated by ~10bp. A new high 19bp above the cycle close high would need a fresh shock. Past runs to 5% (2023, 2006–07) reversed quickly, per Reuters. https://www.investing.com/news/economy-news/us-rate-options-signal-market-can-absorb-higher-treasury-yields-4906084 - [2026-10-13] Oil is the main upside driver, and it fell on the Russia–Ukraine "energy ceasefire" (Brent about $105.7). Real yields drove the rise, not term premium or breakevens, per BlackRock. The 10Y breakeven was only 2.33% on Oct 9, so inflation expectations are not de-anchoring. A CPI beat that is energy-driven and expected is already priced in. https://www.cnbc.com/2026/10/13/us-treasurys-bonds-yields.html - [2026-10-14] Consensus for September CPI: headline 0.6% m/m and 3.7% y/y, with core only 0.2% m/m. Core slowing would support the October pause. A hot headline is expected, and the market is positioned for it. https://www.tradingkey.com/analysis/economic/indicators/262213230-us-september-cpi-outlook-inflation-us-stocks-dollar-gold-reaction-tradingkey BOTTOM LINE: A 5.50% par close needs about +31bp in 14 business days, to a level the 10Y has not closed at in the data cited here, with the Fed, Treasury, big asset managers and the oil trend all leaning against it. The status quo, a 5.2–5.3% range, resolves NO. NOT FOUND: The actual Oct 14 CPI result and market reaction, Treasury's own Oct 14 par yield, and implied-volatility or options pricing for the 10Y in October. I also could not read the full Benzinga page, which returned 403.

(0) The condition is not met. Treasury's own par yield CSV shows an October 10Y high of 5.31% on Oct 5 and a latest print of 5.21% on Oct 13, so nothing has resolved. To resolve YES, a daily par close of at least 5.50% has to print by Oct 30. (a) About 13 business days remain (Oct 14–30), since Oct 31 is a Saturday. (b) If nothing changes, the 10Y stays in its 5.19–5.31% October range and the market resolves NO. Realized October daily moves have been only about 3–5bp, so a 29bp barrier is roughly 2 standard deviations away on realized vol. (c) NO path: CPI and PPI land near consensus, with core around 0.2%. Oil stays contained after the energy ceasefire, and the Fed holds on Oct 28 (about 78–80% priced). Strong auction demand and asset managers buying near 5.2–5.3% cap yields. (d) YES path: a hot core CPI or PPI combines with a renewed Hormuz or Iran oil spike. That revives October hike pricing, and a 15bp-plus day like Sep 23 strings together into a new multi-decade high above 5.50% before month end. The Kalshi anchor is 12% (bid 9 / ask 18). Polymarket's related "5.5% before 2027" at 33% covers a much longer window, so it is consistent with a low single-month probability. Fat-tailed jump risk in this regime justifies more than a pure random-walk estimate, but I shade slightly below the market's 12%.

(0) Not resolved: Treasury's own par-curve export (fetched via its CSV) shows the October 10Y at 5.21–5.31%, peaking at 5.31% on Oct 5 and 5.21% on Oct 13. YES needs a published close of 5.50% or higher, about +29bp, by Fri Oct 30. (a) About 13 business days remain. (b) Status quo of a 5.2–5.3% range resolves NO. (c) NO path: soft core CPI, oil calm after the energy ceasefire, a Fed hold on Oct 28 (about 78–81% priced), strong auction demand, dip buying and Treasury long-end buybacks cap yields. (d) YES path: a hot CPI or PPI plus a renewed Hormuz or Iran oil spike reprices October-hike odds sharply higher and drives a roughly 30bp run, as in the Sep 8–Oct 5 surge. A random-walk barrier estimate with 6–8bp daily vol gives about 15–25%; close-only observation and mean reversion at a multi-decade high bring it to about 10–15%. This matches the Kalshi anchor of 12% and the Polymarket year-end 5.5% market at 33% over a longer window, so I stay near the market. Today's unknown CPI print is the main swing factor.
