final rationale
Mean of 4 draws (0.92, 0.92, 0.92, 0.93). (0) Resolution check: the condition is not documented as met. The official-style daily series (FRED DGS10 / H.15, which tracks Treasury's par curve) printed 5.18% on Sept 24, the day of the 5.223% intraday headline. Secondary trackers put Sept 25 around 5.17%. TradingEconomics shows about 5.21% live on Sept 28, but that is an intraday quote, not Treasury's 3:30pm par-curve print. So YES still needs one official daily print of 5.20% or higher. (a) About three months (~65 trading days) remain until Dec 31, 2026. (b) Status quo: the yield sits only 2-3bp below the strike, the Fed is hiking with about 70% odds of another hike, and PCE (Sep 30), jobs (Oct 2), CPI (Oct 14) and the FOMC (Oct 27-28) are all still ahead. (c) NO: an Iran/Hormuz deal pushes oil lower, data soften, and yields retreat 2023-style, so official closes top out at 5.17-5.19% and then fall. (d) YES: any hot print or hawkish Fed remark yields a 3:30pm snapshot of 5.20% or more, possibly as soon as Sept 28 given the 5.21% live quote. A simple hitting-probability estimate (about 6bp daily volatility, 2bp gap, 65 days) gives well above 90% under zero drift. Discrete daily snapshots and the demonstrated reversibility trim that somewhat. I sit slightly above the 90.6% Polymarket anchor, and the ladder of related contracts (5.4% at 48.5%, 5.5% at 25%) is consistent with that.

Planner reasoning
This is a threshold question on the 10-year Treasury yield, with about three months left in the window. The key inputs are the current and historical DGS10 path from FRED (to see how far the yield sits below 5.2% and whether it has already touched that level), the Treasury par yield page the market resolves on, and the market's own price. Related markets on the Fed and Treasury yields help triangulate.

- current state: Multiple independent market-data sources (CNBC, TradingEconomics, FRED/H.15) confirm the 10-year Treasury yield traded at or above 5.2% intraday, and by some readings closed at/near that level, during the week of September 21–26, 2026, and a live quote for September 28, 2026 again shows ~5.21%; whether Treasury's own official "Daily Treasury Par Yield Curve" 10-year column (the specific resolution source) recorded a print at or above 5.20% on a given day is not fully confirmed from the pages ret
- base rate: Historically, 10Y yields at/above 5% have been rare since 2008 (only a brief 2023 touch before now), making a "5.2%" threshold look like a low-base-rate event in the post-GFC reference class; however, professional forecasters (Blue Chip, CBO, Schwab) have a track record of underestimating recent yield moves and were caught flat-footed by the speed of the 2026 surge, and the yield has now already traded at or above 5.2% on multiple days in late September 2026, so the outside view has effectively

- no case: The strongest NO case rests on a real and evidenced methodology gap — Treasury's official par-yield-curve column is a discretionary, once-daily 3:30pm snapshot, and at least one instance (September 24, 2026) shows it printing 5.18%, distinctly below the 5.20% strike, on a day intraday/news headlines cited 5.22-5.23%; combined with the demonstrated reversibility of the move (oil/Iran de-escalation, hawkish-vs-dovish Fed repricing) and the rarity of sustained 5%+ prints historically, there remains

- [2026-09-25] TradingEconomics reported the 10-year yield "eased below 5.2%" on Friday but "stayed close to its highest level since 2007," following a three-session sell-off that had pushed the yield up 23bps to around 5.20%. [https://tradingeconomics.com/united-states/government-bond-yield]
- [2026-09-26] A CNBC retrospective piece stated the 10-year yield "surged to 5.23%... its highest level since 2007," attributing the move to sticky inflation, rate expectations and heavy government/corporate bond issuance. [https://www.cnbc.com/2026/09/26/10-year-treasury-yield-is-at-its-highest-in-19-years-how-we-got-here.html]
- [2026-09-25] Later-week data (TradingEconomics, MacroMicro, Forbes) show the 10-year settling back to roughly 5.17%-5.18% by Friday, still a multi-decade high but below the 5.2% threshold on a closing basis per these secondary trackers. [https://en.macromicro.me/series/354/10year-bond-yield]
- [2026-09-25] Forbes Advisor's daily Treasury rates snapshot put the 10-year note yield at 5.17% as of 3:30 p.m. ET, noting the past-year high was 5.18% (Sept. 24). [https://www.forbes.com/advisor/investing/treasury-rates/]
- [2026-09-16] At the September FOMC meeting the Fed delivered a rate hike (not a cut), with Chair Kevin Warsh attributing higher 10-year yields to "economic strength, competition for capital and geopolitical factors," and market pricing has shifted from expecting cuts to pricing further hikes. [https://www.ishares.com/us/insights/portfolio-insights/fed-outlook-rates-kevin-warsh-fixed-income-2026]
- [2026-09-25] Markets are pricing roughly a 66-70% probability of another 25bp Fed hike at the next meeting, with swaps pricing in up to three additional quarter-point hikes over the coming year — a backdrop that has kept term premia and long yields elevated. [https://tradingeconomics.com/united-states/government-bond-yield]
- [2026-09-02] Earlier in September the 10-year yield had reached only 4.818% intraday (highest since Nov. 2023), showing the move above 5% and toward 5.2%+ occurred rapidly within the same month. [https://www.cnbc.com/2026/09/02/bond-yields-treasurys-inflation.html]
- [2026-09-16] The September Fed dot plot showed the median 10-year and short-rate projections shifting hawkish, with the 10- and 20-year Treasury yields closing at 5.01% and 5.39% respectively immediately after the hike decision, underscoring the rapid subsequent move to the 5.2% area within days. [https://www.bondsavvy.com/fixed-income-investments-blog/fed-dot-plot]
- [2026-09-28] TradingEconomics' live quote (dated to today) shows the 10-Year Note yield at 5.21%, "near its highest level since mid-2007," with traders citing hawkish Fed commentary and stalled US-Iran talks as drivers of continued elevated yields. [https://tradingeconomics.com/united-states/government-bond-yield]
BOTTOM LINE: Multiple independent market-data sources (CNBC, TradingEconomics, FRED/H.15) confirm the 10-year Treasury yield traded at or above 5.2% intraday, and by some readings closed at/near that level, during the week of September 21–26, 2026, and a live quote for September 28, 2026 again shows ~5.21%; whether Treasury's own official "Daily Treasury Par Yield Curve" 10-year column (the specific resolution source) recorded a print at or above 5.20% on a given day is not fully confirmed from the pages retrieved, since Treasury's own site did not return the specific data table in this session, but the closely related FRED/H.15 CMT series and multiple news outlets place the yield squarely at the threshold in late September 2026.
NOT FOUND: The exact daily closing figures from the official Treasury.gov "Daily Treasury Par Yield Curve Rates" page (10 Yr column) for September 22–28, 2026 could not be retrieved directly in this session (the page returned only navigation content, not the data table); this would be the definitive tie-breaker on whether the official resolution source shows a value ≥5.20%.
report: base rate
- [2026-09-24]
The benchmark 10-year Treasury note yield, tied to rates on mortgages, surged more than 10 basis points to 5.223%, levels not reached since June 2007
, and the 30-year hit its highest since June 2004. https://www.cnbc.com/2026/09/24/us-treasury-yields-bonds-fed-inflation.html
- [2026-09-26]
The 10-year Treasury yield surged to 5.23% on Friday, its highest level since 2007
, up from
just below 4.8% earlier that same month
— an extremely rapid, historically unusual move. https://www.cnbc.com/2026/09/26/10-year-treasury-yield-is-at-its-highest-in-19-years-how-we-got-here.html
- [2026-09-15] Reference class for "5%+" crossings:
the 10-year yield hitting 5% was a level briefly touched in 2023 and otherwise not seen since 2007
, showing that even the 5% threshold (below this question's 5.2% strike) is a rare historical event, occurring only twice since the 2007-08 financial crisis before this year. https://www.cnn.com/2026/09/14/investing/bond-yields-market-turmoil
- [2026-09-22] Prior 5%+ episode was brief and reversed:
from around 1.5% at the end of 2021, the yield climbed above 4% in 2022 and flirted with 5% in 2023, crossing 5% intraday in October 2023, but did not stay there as the yield fell on anticipated Fed cuts
. This is the closest historical analogue for "touch vs. sustain" dynamics relevant to a threshold-crossing contract. https://fortune.com/2026/09/22/10-year-treasury-yield-5-2007-stagflation-1970s/
- [2026-09-24] Longer-run base rate context:
the 10-year Treasury averaged about 5.9% from 1990 through 2006
, so current 5.2% levels, while extreme relative to the post-2008 era, are not extreme relative to the pre-financial-crisis decades — a reminder that the "low-rate era" reference class (2008–2021) may be the wrong base rate. https://www.cnbc.com/2026/09/24/treasury-yields-warsh-bessent-fed-national-debt-analysis.html
- [2026-09-27] Trading Economics daily update shows the yield
rose to 5.21% on September 28, 2026, marking a 0.05 percentage point increase from the previous session
, confirming levels around/above the 5.2% strike were reached on multiple separate days in the final week of September 2026, not just a single fleeting print. https://tradingeconomics.com/united-states/government-bond-yield
- [2026-09-26] Speed/velocity base rate:
the 10-year yield saw its most rapid one-day increase since April 7, 2025, rising further to top 5.17%, considering two weeks earlier it was below 4.8% and in August it was below 4.6%
— illustrating how fast this specific move has occurred relative to typical historical yield changes over a similar span. https://www.cnbc.com/2026/09/24/history-shows-financial-calamities-occur-when-rates-rise-rapidly-like-this-something-always-breaks.html
- [2026-09-23] Forecaster track record (CBO):
according to the CBO's most recent forecasts issued in February, the 10-year yield was seen at 4.1% this year and 4.2% in 2027; those projections seem quaint now, given the yield has already blown past the CBO's long-term outlook
, illustrating that official long-range forecasts badly underestimated the level reached by late 2026. https://fortune.com/2026/09/26/us-debt-outlook-cbo-10-year-treasury-bond-yields-highest-two-decades/
- [2025-12] Blue Chip consensus forecaster track record (St. Louis Fed analysis): historically,
the mean forecast error on the 10-year Treasury yield forecast is -0.4 percentage points, indicating that forecasters have typically predicted higher interest rates by an average of 40 basis points
than actual — meaning professional forecasters have historically been biased toward overestimating yields, the opposite of what has happened in 2026's surprise upside surge.
- [2026-06-24] Mid-year Wall Street consensus (Schwab) illustrates how quickly views changed: as of June 2026 the house view was that
the 10-year Treasury yield may hold in the 4% to 4.5% range it has mostly held since early March, although there are risks to the upside
— a forecast that was overtaken within three months by the actual move to 5.2%+. https://www.schwab.com/learn/story/fixed-income-outlook
- [2026-09-25] Contemporary framing from strategists treats current levels as a regime change rather than a fluke:
elevated inflation, especially higher oil prices, combined with expectations that the Fed will hike rates at least one more time this year, helped drive the 10-year Treasury yield to 5.208% on Thursday — the highest it's been since June 2007
, with Bloomberg separately describing this as "a fundamental shift" in the rate regime rather than a temporary spike. https://www.cnbc.com/2026/09/25/treasury-yield-buy-bonds.html
BOTTOM LINE: Historically, 10Y yields at/above 5% have been rare since 2008 (only a brief 2023 touch before now), making a "5.2%" threshold look like a low-base-rate event in the post-GFC reference class; however, professional forecasters (Blue Chip, CBO, Schwab) have a track record of underestimating recent yield moves and were caught flat-footed by the speed of the 2026 surge, and the yield has now already traded at or above 5.2% on multiple days in late September 2026, so the outside view has effectively been overtaken by the inside-view/current-trend evidence.
NOT FOUND: A specific Polymarket, Kalshi or other prediction-market historical base rate for exactly-this-contract-type ("Treasury yield hits X by date") resolutions; no dedicated poll or survey of professional forecasters specifically estimating probability of touching 5.2% (as opposed to point forecasts) was located.
report: yes case
YES means: the Treasury's official Daily Treasury Par Yield Curve "10 Yr" column prints a value of 5.20% or higher on at least one day between 2025-11-11 and 2026-12-31 (the market resolves Yes as soon as that threshold is met and need not wait for year-end).
- [2026-09-28] TradingEconomics' benchmark quote (the closest public proxy to the Treasury par-curve series) shows the 10-year yield
rose to 5.21% on September 28, 2026, marking a 0.05 percentage point increase from the previous session
, i.e. a fresh push above the 5.20% strike on the very day of this report.
- [2026-09-25] A third-party live tracker (dealplexus) recorded, as of the same week, a 10-year
Day High of 5.23% and a 52-Week High of 5.23%, with an intraday Open of 5.20%
, corroborating that the yield has repeatedly traded above the strike, not just once.
- [2026-09-25] CNBC's own data confirms the multi-day persistence of levels at/above the threshold: the benchmark yield was
"up less than 1 basis point to 5.163% after reaching its highest rate since June 2007 on Thursday"
(i.e., Sept. 24), showing the market has been oscillating around, and repeatedly through, the 5.2% level rather than spiking once and reversing.
- [2026-09-24] A separate close-of-day snapshot (sofrrate.com, sourced from FRED) put the 10-year yield at
5.18%, the 2-year at 4.87%, and the 30-year at 5.47%, as of September 24, 2026
, with the 2s10s spread near +31bp — evidence that the curve-wide repricing, not just a single noisy print, is what's carrying the 10-year toward and through 5.2%.
- [2026-09-26] The macro driver is structural, not one-off: primerates.com's tracker notes
"On September 16 the Fed raised its target range a quarter point to 3.75% to 4.00% in a unanimous 12-0 vote, a hawkish turn after a run of holds, judging that inflation remains too high," with August CPI at 3.4% headline and 2.4% core, still above target, and a firmer August jobs report
— a hiking, not cutting, Fed removes the main historical mechanism (2023's episode) that previously capped yields just below 5%.
- [2026-09-26] Forward policy pricing points the same way: markets are pricing further tightening, not a pivot, with
"odds of another 25bps rate hike at the Fed's next meeting currently stand at around 70%, while swaps are pricing in three additional quarter-point rate increases over the next year"
— if delivered, this raises short rates and term premium simultaneously, a combination that historically pushes the 10-year higher rather than triggering a 2023-style reversal.
- [2026-09-26] Next scheduled data catalysts that could extend the move are imminent and clustered: primerates.com flags
the August PCE report on September 30, the September jobs report on October 2 and September CPI on October 14, with the next FOMC meeting October 27-28, 2026
— each is a plausible trigger for another leg higher if inflation or labor data surprise hot, well within the 15-month resolution window.
- [2026-09-25] Even the modest pullback documented this week left the yield only fractionally below the strike, not decisively below it: TradingEconomics notes the yield
"fell to 5.17% on Friday, following a sharp sell-off over the previous three sessions that pushed the benchmark yield up 23bps to around 5.20%," with only "a decline in oil prices... providing some relief"
— a fragile, reversible dip rather than a durable retreat.
- [2026-09-25] The methodological point that favors YES: the Treasury par-curve print is a single daily value derived from ~3:30pm bid quotes, and TradingEconomics itself frames current levels as being "near its highest level since mid-2007" even on the lower-print Friday, meaning the series has been running right at the door of 5.20% on trend, so any renewed bout of hawkish data (per the above calendar) is likely sufficient to produce an official print at or above the strike, if it has not already done so on Sept. 24 or Sept. 28.
BOTTOM LINE: Multiple independent trackers (TradingEconomics, CNBC, sofrrate/FRED, dealplexus) show the 10-year yield trading at, above, or within a few basis points of 5.20% on several distinct days in the week of Sept. 21–28, 2026, driven by a hawkish, still-hiking Fed and sticky inflation, with several major data/FOMC catalysts still ahead before the Dec. 31, 2026 deadline — making a YES resolution (an official Treasury par-curve print ≥5.20%) look highly likely to have already occurred or to occur imminently.
NOT FOUND: The exact official Treasury.gov "Daily Treasury Par Yield Curve Rates" table entries for the 10-year column on Sept. 24 and Sept. 28, 2026 could not be retrieved directly (the page returned only site navigation, not the data table), so confirmation rests on closely correlated secondary series (FRED/CMT, TradingEconomics, CNBC) rather than the primary resolution source itself.
report: no case
YES means: the U.S. Treasury's own "Daily Treasury Par Yield Curve Rates" 10-Year column prints a value of 5.20% or higher on at least one business day between November 11, 2025 and December 31, 2026.
- [2026-09-24] The Treasury par-yield-curve methodology is a single daily snapshot, not an intraday high:
it is based on the closing market bid prices on the most recently auctioned Treasury securities, derived from indicative bid-side quotations obtained by the Federal Reserve Bank of New York at or near 3:30 PM each trading day
. This means the widely-reported 5.223% and 5.22-5.23% "surge" figures from CNBC, which describe intraday trading swings, are not necessarily what prints in the official resolution-source column.
- [2026-09-24] A third-party site that states its data is sourced directly from the Fed/Treasury par curve reported
the 10-year Treasury yield is 5.18%... as of September 24, 2026
, i.e., on the very day CNBC's intraday headline cited 5.223% — indicating the official constant-maturity snapshot stayed below the 5.20% strike even on the day of the reported intraday peak.
- [2026-09-24] FRED's DGS10 (the Fed's H.15 release, methodologically identical to Treasury's par-curve CMT figure) recorded exactly 5.18% for September 24, 2026, confirmed again in a direct search of the FRED series page, reinforcing that the specific resolution-source-style measure has not been shown at or above 5.20% on this date.
- [2026-09-25] TradingEconomics' own day-by-day narrative shows the yield pulling back to 5.17% on Friday September 25 after the multi-session sell-off, describing the move as having "pushed the benchmark yield up 23bps to around 5.20%" — language of "around," not "at or above," on a closing basis, and consistent with the official series staying just under the strike.
- [2026-09-25] Even TradingEconomics' own live-quote framing on September 25 hedged with "eased below 5.2%" language, describing the 10-year as staying "close to" but not confirmed over its highest level since 2007, underscoring that even non-Treasury commercial trackers are not uniformly confirming a sustained close at/above 5.20%.
- [2026-09-16] Treasury's own par-curve rates are explicitly discretionary in construction:
Treasury reserves the option to make changes to the yield curve as appropriate and in its sole discretion
, meaning small methodological choices (spline interpolation, most-recently-auctioned security selection) could keep the official print a few basis points below unofficial intraday or composite-index readings even during a broad market sell-off.
- [2026-09-24] Historical status-quo inertia: the reference class shows 10-year yields at/above 5% have been extraordinarily rare since 2008, with only a brief touch in 2023, and the "touch vs. sustain" pattern from October 2023 (crossing 5% intraday, then reversing on rate-cut expectations) is the closest analogue — implying that even if intraday levels flirt with 5.20%, the officially recorded daily par-curve print has a plausible path to stay just under the line if any reversal (e.g., an Iran deal, easing oil prices, or a dovish Fed surprise) intervenes before the next official snapshot.
- [2026-09-25] A concrete near-term reversal catalyst already exists in the data:
the 10-year yield fell to 5.17% on Friday, following a sharp sell-off, aided by a decline in oil prices amid signs that US and Iranian negotiators may be exploring a phased agreement to reopen the Strait of Hormuz
— showing the move is reversible on short notice, which matters for a discrete, once-daily-snapshot resolution source rather than a continuous intraday tape.
- [2026-09-28] The single most current on-the-record commercial quote (TradingEconomics) put the yield at 5.21% for September 28, but this is again a market-tracker "quote," not confirmed language from Treasury's own par-yield-curve table for that date, leaving open the technical possibility that Treasury's own 3:30pm-snapshot print differs from the quoted level by a few basis points, as it reportedly did on September 24 (5.18% official vs 5.22-5.23% intraday headlines).
BOTTOM LINE: The strongest NO case rests on a real and evidenced methodology gap — Treasury's official par-yield-curve column is a discretionary, once-daily 3:30pm snapshot, and at least one instance (September 24, 2026) shows it printing 5.18%, distinctly below the 5.20% strike, on a day intraday/news headlines cited 5.22-5.23%; combined with the demonstrated reversibility of the move (oil/Iran de-escalation, hawkish-vs-dovish Fed repricing) and the rarity of sustained 5%+ prints historically, there remains a plausible, evidence-backed path for the official resolution series to keep closing just under 5.20% even amid a broader market narrative of "yields near 5.2%."
NOT FOUND: The exact verbatim numeric row from home.treasury.gov's "Daily Treasury Par Yield Curve Rates" TextView table for the 10-Year column on each date September 22–28, 2026 could not be directly retrieved in this session (the page returned only navigation/methodology text, not the data table); no independent, non-tracker confirmation that Treasury's own official series has (or has not) already printed ≥5.20% on any specific date was found, leaving this the decisive unresolved technicality.

(0) Resolution check: the condition is not documented as met. The official-style daily series (FRED DGS10 / H.15, which tracks Treasury's par curve) printed 5.18% on Sept 24, the day of the 5.223% intraday headline. Secondary trackers put Sept 25 around 5.17%. TradingEconomics shows about 5.21% live on Sept 28, but that is an intraday quote, not Treasury's 3:30pm par-curve print. So YES still needs one official daily print of 5.20% or higher. (a) About three months (~65 trading days) remain until Dec 31, 2026. (b) Status quo: the yield sits only 2-3bp below the strike, the Fed is hiking with about 70% odds of another hike, and PCE (Sep 30), jobs (Oct 2), CPI (Oct 14) and the FOMC (Oct 27-28) are all still ahead. (c) NO: an Iran/Hormuz deal pushes oil lower, data soften, and yields retreat 2023-style, so official closes top out at 5.17-5.19% and then fall. (d) YES: any hot print or hawkish Fed remark yields a 3:30pm snapshot of 5.20% or more, possibly as soon as Sept 28 given the 5.21% live quote. A simple hitting-probability estimate (about 6bp daily volatility, 2bp gap, 65 days) gives well above 90% under zero drift. Discrete daily snapshots and the demonstrated reversibility trim that somewhat. I sit slightly above the 90.6% Polymarket anchor, and the ladder of related contracts (5.4% at 48.5%, 5.5% at 25%) is consistent with that.

(0) Not confirmed met: FRED/H.15 DGS10 printed 5.18% on Sept 24 despite 5.22-5.23% intraday headlines, Sept 25 was ~5.17%, and the 5.21% for Sept 28 is a TradingEconomics quote, not the official 3:30pm par-curve print; the Treasury table was not retrieved. YES needs one official 10 Yr close at or above 5.20%. (a) About three months (~65 trading days) remain until Dec 31, 2026. (b) Status quo: yield at ~5.17-5.21%, only 2-3bp below the strike; with daily moves of ~5-8bp a touch is highly likely. (c) NO: a US-Iran deal lowers oil, data soften and the Fed pauses, reversing yields as in 2023 without another official close at or above 5.20%. (d) YES: PCE (Sept 30), jobs (Oct 2), CPI (Oct 14) or the Oct 27-28 FOMC (hike priced ~70%) pushes one official close to 5.20%+, possibly as soon as Sept 28. The 90.6% market anchor is consistent with the 5.4% contract at 48.5%; I shade up slightly for the hawkish backdrop and catalysts, tempered by the snapshot-methodology gap.

(0) The resolving condition is not definitively documented as already met: Treasury's official table was not retrieved, while the closely related FRED DGS10 series recorded only 5.18% on September 24 despite intraday reports of 5.22%-5.23%. (a) About 94 days remain through December 31, 2026, and an official Treasury 10 Yr daily print of at least 5.20% is still required unless an earlier qualifying print is later confirmed. (b) If nothing changes from the latest confirmed resolution-style reading of 5.18%, the market resolves No, although TradingEconomics' September 28 quote of 5.21% suggests the threshold may already have been reached in the market and possibly in Treasury's daily snapshot. (c) No results if yields retreat before an official 3:30 p.m.-style Treasury observation reaches 5.20%, potentially because inflation cools, geopolitical risks ease, or Fed expectations turn dovish. (d) Yes results if the September 28 Treasury value confirms the reported 5.21% level or if any further hawkish inflation, employment, or Fed catalyst lifts the official daily print by the few basis points needed. I anchor on Polymarket's 90.6% Yes price and move modestly higher to 92% because the yield is already at the threshold on multiple current secondary sources, while retaining meaningful resolution-source and snapshot-methodology risk.

(0) The resolving condition may already have been met, but this is not confirmed: TradingEconomics shows 5.21% on September 28 and news sources report intraday highs of 5.208%-5.223%, while the actual Treasury table was unavailable and FRED recorded only 5.18% on September 24. (a) About 94 days remain through December 31, 2026, during which one official Treasury 10 Yr daily print at or above 5.20% would suffice. (b) If nothing changes from the latest confirmed resolution-source-style observation of 5.18%, the market resolves No, although the yield is only two basis points short. (c) A No scenario is that the Treasury's 3:30 p.m. daily snapshot continues undershooting intraday quotes and yields retreat on softer inflation, geopolitical de-escalation, or dovish Fed repricing. (d) A Yes scenario is that September 28's roughly 5.21% level appears in the official table, or any hot inflation, employment, or Fed catalyst produces another rise of only a few basis points before year-end. Anchoring on Polymarket's 90.6% Yes price, I move modestly upward because the latest proxy is already above the threshold and repeated near-threshold trading plus substantial time remaining creates multiple opportunities for an official qualifying print, while retaining 7% for the unresolved methodology and source-data gap.
