final rationale
Mean of 2 draws (0.76, 0.75). (0) Not yet met: Treasury's par-curve CSV shows a window high of 5.09% (Sep 30) and 5.00% on Oct 13-14; intraday spikes above 5.10% don't count. (a) About 54 trading days remain to Dec 31. (b) Status quo at 5.00% is No, but the strike is only 10bp away. (c) No: the CPI shock fades, Fed speakers cap the hike path, and risk-off from chip/AI credit stress pulls yields down, leaving repeated failures at 5.06-5.09%. (d) Yes: hot PPI or jobs data, a weak Oct 27 5-year auction, or a hawkish Oct 28 or Dec 9 FOMC pushes one close to 5.10%+. With realized vol near 5-7bp a day, a zero-drift first-passage estimate for a 10bp barrier is about 80%, trimmed slightly for discrete closes. That is consistent with the Polymarket anchor of 76%, so I stay near the market.

Planner reasoning
This question asks whether the 5-year Treasury yield touches 5.10% before the end of 2026. The resolution page (Treasury par yield curve) and FRED DGS5 give the current level and the path since September 3, including whether the threshold has already been hit. Fed funds and the 10-year yield add context on where rates are heading. The market's own Polymarket price is the anchor, and related rate and yield markets on both venues serve as a cross-check.

In the Treasury's Daily Par Yield Curve CSV for 2026, the latest 5 Yr reading is 5.00% on 10/14/2026, and it was also 5.00% on 10/13. The highest 5 Yr value between Sep 3 and Oct 14, 2026 is 5.09% on 09/30/2026, just under the 5.10% threshold. Other high readings in that window: 5.06 (9/28, 9/29, 10/2, 10/5) and 5.03 (10/6, - fred: Fetched 4 FRED series (lookback=120d). - polymarket_related: Polymarket search over 2 keyword(s), kept 10 matches. keyword 'treasury yield': 5 markets | keyword 'fed rate': 5 markets - kalshi_related: 2 related markets / summaries. keyword 'treasury yield': ok | keyword 'fed rate': ok Research loops, bottom lines - current state: The 5-year par yield is about 5.00-5.05%, roughly 5-10bp below the 5.10% strike. The 2026 high is 5.09% on Sep 30, so no qualifying close has been seen. A hot CPI, hike risk, and a global bond selloff keep the level close, with Oct 28 FOMC, Dec 9 FOMC, and data releases still ahead. - base rate: The 5-year Treasury sits about 10 bp below the strike, near the top of its range (a 5.09% close on 9-30). Over 54 trading days, a first-passage touch of a level that close is historically common for a series with 3–8 bp daily moves. Momentum is hawkish (Fed hiking, markets pricing more hikes than the Fed projects), but yields have eased from the early-October peak, and model forecasts that expected falling yields have been wrong. - yes case: The 5Y par close is 5.00% on the Treasury's own data, 10bp short of the strike. The 2026 closing high is 5.09%, and the intraday spike through 5.15% on Oct 14 shows how little a hot print needs to push it over. Hawkish Fed pricing, record-weak auction demand and bearish forecaster revisions give several dated catalysts (Oct 15 PPI, Oct 27 auction, Oct 28 and Dec 9 FOMC) before year-end. - no case: The best No case is that 5.10% has been tested at least three times (Sep 30, Oct 2, Oct 14) and each time failed on the daily close. The Fed's own projections and speakers point to one more hike, not a sustained tightening cycle, and risk-off episodes pull yields back. The weakness of this case is that the strike is only 5–10bp away with 54 trading days left and a Dec 9 FOMC still to come.

The Sep 30 close is 5.09% on the par curve per a monthly report, and the 5-year was up 60bp since Aug 31. Neither source shows 5.10% reached on a daily close. Source: https://www.macrotrends.net/2522/5-year-treasury-bond-rate-yield-chart - [2026-10-01] Intraday highs exceeded 5.10% without a qualifying Treasury close. Oct 1 intraday high was 5.135% and the 52-week high was 5.14% on 10/01. The Oct 5 intraday high was 5.099%. The resolution source uses daily par yields, not intraday quotes. Source: https://www.cnbc.com/quotes/US5Y - [2026-10-14] The September CPI came in hot at 3.7% year on year. Core CPI was 2.6% against 2.5% expected. The 10-year was up 6bp to 5.27% intraday. Source: https://finance.yahoo.com/markets/live/stock-market-today-hot-inflation-report-drops-tech-drives-sp-500-nasdaq-down-152206632.html - [2026-10-14] After CPI, Reuters said the implied probability of an Oct hike rose from about 22% to about 40%. CNBC cited CME FedWatch at 67% for a hold at the Oct 27-28 meeting, with about 79bp of tightening priced by late 2027. The dollar hit an 18-month high.

Three members had wanted a hike in July. The Sep minutes (released Oct 7) showed all participants backed the hike and almost all saw upside inflation risks. Source: https://primerates.com/primerate/fed-meeting-schedule/ - [2026-10-07] The 10-year hit a roughly 24-year high of about 5.37% on Oct 7, then backed off after a solid auction. Global bond selloff drivers include French fiscal worries and IMF debt warnings.

Brokerages mostly expected a hold in October. Source: https://admiralmarkets.com/analytics/traders-blog/fed-rate-decision-october-2026 BOTTOM LINE: The 5-year par yield is about 5.00-5.05%, roughly 5-10bp below the 5.10% strike. The 2026 high is 5.09% on Sep 30, so no qualifying close has been seen. A hot CPI, hike risk, and a global bond selloff keep the level close, with Oct 28 FOMC, Dec 9 FOMC, and data releases still ahead. NOT FOUND: Treasury's own Oct 2026 par-curve table values (the page returned no table rows); a confirmed Oct 14 Treasury 5 Yr close; any day with a Treasury 5 Yr of 5.10% or higher.
report: base rate
- [2026-10-14] The Treasury par 5-year yield was 5.00% (+0 bp on the day). That is 10 bp below the 5.10% strike. The 5-year was 5.00% on 10-13, 5.02% on 10-09, 4.99% on 10-08 and 5.03% on 10-07. https://stockmarketwatch.com/bonds/5-year-treasury-yield - [2026-10-13] FRED/H.15 (Fed constant-maturity series) shows 5.00% for 10-13. Its recent prints are 5.02, 4.99 and 5.03. This series differs slightly from the Treasury par curve, but only by rounding. https://fred.stlouisfed.org/series/DGS5 - [2026-09-30] The highest official close in the window so far is about 5.09% on 9-30, still below 5.10%. Macrotrends gives a 52-week range of 3.51% (2026-02-27) to 5.09% (2026-09-30). The Treasury curve table also shows 5Y at 5.09%, up 60 bp since 8-31 and up 136 bp year to date. https://www.macrotrends.net/2522/5-year-treasury-bond-rate-yield-chart - [2026-10-06] Mortgagenewsdaily's intraday market data shows 5.135 on 10-01 and 5.099 on 10-05. Yahoo's 52-week high is 5.153, and CNBC's is 5.136 on 10-01. These intraday prints exceeded 5.10% but are not the Treasury's daily par close. The resolution source is the Treasury close, so those intraday spikes likely do not count. I did not confirm that the Treasury par column itself has never printed ≥5.10%; the Treasury page was served without its table rows. https://www.mortgagenewsdaily.com/treasury/5yr - [2026-10-01] BBVA reports that the Fed raised rates 25 bp to 3.75–4.00% about two weeks earlier. The median FOMC projection implies one more hike. Markets price 3–4 more hikes by Sep 2027, which is more than the Fed signals. BBVA says the 10-year is near 5.3% and that most of the rise comes from higher expected short-term real rates, not term premium. https://www.bbvaresearch.com/wp-content/uploads/2026/10/US_Interest_Rates_Monitor_October_26_ENG.pdf - [2026-10-14] CME FedWatch year-end 2026 probabilities (via MacroMicro): 69.7% for 4.00–4.25%, 18.3% for 4.25–4.50%, 12% for 3.75–4.00%. The market therefore expects roughly one more hike by December. https://en.macromicro.me/collections/51/us-treasury-bond/144242/us-number-yearend-rate-2026 - [2026-10-14] The wider curve: 2Y 4.82%, 10Y 5.19%, 30Y 5.52%. Over the past month the 5Y is up about 20 bp. The 10Y hit a 24-year high of about 5.37% on 10-07 and has since eased. https://www.cnbc.com/quotes/US10Y - [2026-10-09] Yields have retreated modestly from the 9-30/10-01 peak. The 10Y was 5.24% on 10-09, and Freddie Mac's 30-year mortgage rate was 7.40%. https://www.etftrends.com/fixed-income-content-hub/treasury-yields-snapshot-october-9-2026/ - [2026-07-27] Statistical forecasts have been far below the market. Forecasts.org (a model from June–July) projected the 5Y at about 4.08% for Oct 2026 and 3.94% for Dec 2026. Trading Economics (March) projected 3.74% for the 12 months from March. Both badly underestimated the move, so these forecasts have a poor record this year. https://www.forecasts.org/5yrT.htm - [2026-10-14] Base-rate framing from the data: with the spot yield at 5.00% and 5.10% about 10 bp away, the strike is within a routine daily-to-weekly range. The 5Y moved 3–8 bp per day in early October, with a 2–3 week realized range of about 4.99–5.09%. About 2.5 months remain (roughly 54 trading days). The closing-high threshold has been tested once, at 5.09% on 9-30, and not exceeded. This is my own calculation from the cited data. BOTTOM LINE: The 5-year Treasury sits about 10 bp below the strike, near the top of its range (a 5.09% close on 9-30). Over 54 trading days, a first-passage touch of a level that close is historically common for a series with 3–8 bp daily moves. Momentum is hawkish (Fed hiking, markets pricing more hikes than the Fed projects), but yields have eased from the early-October peak, and model forecasts that expected falling yields have been wrong. NOT FOUND: The Treasury's par-curve table rows, because the page was served without its data. I also found no confirmed Treasury par-curve value ≥5.10% in the window, no expert forecast of the 5Y specifically for Q4 2026, and no sibling-strike or other-venue market prices.
report: yes case
YES means: the Treasury Daily Par Yield Curve "5 Yr" column prints 5.10% or higher for any date from Sept 3 to Dec 31, 2026. - [2026-10-14] I read the Treasury's own par-curve CSV, which fills the gap the colleagues' reports left. The 5 Yr closed at 5.00% on Oct 14 and 5.00% on Oct 13. The 2026 closing high is 5.09% on Sep 30, and 5.06% on Oct 2 and Oct 5. No 2026 close is at or above 5.10%. The 7 Yr was 5.09% on Oct 14 and 5.19% on Sep 30, so the 5Y is only a few bp short of 5.10. https://home.treasury.gov/resource-center/data-chart-center/interest-rates/daily-treasury-rates.csv/2026/all?type=daily_treasury_yield_curve&field_tdr_date_value=2026&page&_format=csv - [2026-10-15] The Oct 14 close gave back an intraday spike. After the hot CPI the 5-year topped 5.15% for the first time since 2007, per a market wrap. The 2Y briefly jumped about 15bp to 4.95% and ended flat at 4.80%. Treasuries recovered most of the losses as stocks fell (a chip rout). So the market has already traded 5-10bp through the strike on a single data shock. A similar shock that holds into the 3:30pm close would resolve YES. https://marketindex.com.au/news/asx-200-live-today-thursday-15th-october - [2026-10-14] Fed hike pricing is a direct driver of the 5Y. Pricing of an Oct 28 hike rose to 43% from 22% after CPI. A December hike stands near 95% (CME FedWatch). https://www.fxstreet.com/news/swiss-franc-slides-as-hot-us-inflation-reinforces-hawkish-fed-outlook-202610141544 - [2026-10-14] A Kalshi/Polymarket read puts a hike before 2027 at about 87%, with Dec 9 alone at 79%. Another source, dated Oct 14, has a hike at roughly 34% for Oct 28. If the Fed hikes on Oct 28, which is not the base case, the 2Y-5Y complex would likely reprice upward. Bank of America calls for hikes in both October and December. https://defirate.com/prediction-markets/fed-decision-odds/ ; https://finance.yahoo.com/economy/policy/articles/october-fed-rate-hike-hinges-232828169.html - [2026-10-15] A swing-factor indicator comes next. PPI is consensus +0.5% and retail sales +0.3% on Oct 15. Schwab notes that CPI is moving "opposite of the way the Fed wants" and that core services CPI rose about 0.4%, led by shelter. One-year inflation expectations of 3.9% (NY Fed) are the highest since May 2023. A hot PPI would be the nearest trigger for a push to 5.10%. https://www.schwab.com/learn/story/stock-market-update-open ; https://stockmarketmoods.substack.com/p/sooner-not-higher - [2026-09-23] Supply and demand are a second channel. The Sep 23 $70B 5-year auction cleared at 5.033%, 3.1bp above the when-issued yield, with bid-to-cover 2.21, the weakest since Dec 2018. The 5Y par yield rose 16bp that day, from 4.83% to 4.99%. The next 5-year auction is Oct 27 ($70B, per the Treasury's schedule), one day before the FOMC. A tail there would add to the pressure. https://www.tftc.io/5-year-treasury-auction-5-percent-yield-second-biggest-tail-record ; https://home.treasury.gov/system/files/221/Tentative-Auction-Schedule.pdf - [2026-10-07] Long-end auctions also showed weak demand. The Oct 7 10-year reopening cleared at 5.300%, the highest since Nov 2000. The Oct 8 30-year cleared at 5.618% with bid-to-cover 2.54. The long-end weakness could feed the 5Y if a risk-off or term-premium episode recurs. https://www.tftc.io/treasury-auctions ; https://thevaultreport.com/treasury-auctions - [2026-10-13] Forecasters are leaning bearish for bonds (higher yields). A WSJ survey of 71 economists, taken Oct 2-7, sees the 10Y staying above 5%, with Sinai calling for 6% next year. PIMCO's Ivascyn says forced selling by leveraged holders could push the 10Y toward 6%. Citigroup added a December hike to its forecast. The 10Y at 5.19% is already above the 5Y par yield by about 19bp. A 10Y of 5.30% would leave the 5Y near the strike if the 5Y-10Y gap held. https://en.sedaily.com/international/2026/10/13/us-10-year-yield-could-hit-6-percent-economists-warn ; https://finance.yahoo.com/markets/stocks/articles/pimco-warns-10-treasury-yield-155045650.html - [2026-09-14] Standard Bank (Barrow) raised its 10Y forecasts to 5.2% for year-end and 5.3% for Q1 2027. The 10Y has already passed the year-end target (5.19% on Oct 14 after a 5.28% close on Oct 7). Forecasts are lagging the market. https://www.bloomberg.com/news/articles/2026-09-14/strategist-who-foresaw-10-year-treasuries-at-5-says-selloff-isn-t-done-yet - [2026-10-14] Realized volatility makes a 10bp move routine. In the Treasury CSV the 5Y moved +16bp on Sep 23, +11bp on Sep 10 and Sep 9 combined (from 4.57% to 4.75%), and about 60bp from Aug 31 to Sep 30. Daily moves of 5-10bp are common. About 54 trading days remain with a 10bp gap. The primary YES path needs only one close at 5.10% or higher. https://home.treasury.gov/resource-center/data-chart-center/interest-rates/daily-treasury-rates.csv/2026/all?type=daily_treasury_yield_curve&field_tdr_date_value=2026&page&_format=csv - [2026-10-14] Most likely YES path: PPI and retail data on Oct 15, then the Oct 27 5-year auction and an Oct 28 FOMC that either hikes or signals a Dec hike. After that come the Nov 6 jobs report and the Nov CPI. It needs the market to price roughly 10-20bp more tightening (December hike plus 2027 hikes) or a renewed global term-premium selloff. The Fed could also tighten more than the roughly 79bp already priced. Oil and Iran-war supply shocks add inflation risk. The Dec 8-9 FOMC with a new dot plot is a late catalyst. https://www.cnbc.com/2026/09/23/market-sees-next-fed-hike-in-october-following-barr-comments-hot-inflation.html BOTTOM LINE: The 5Y par close is 5.00% on the Treasury's own data, 10bp short of the strike. The 2026 closing high is 5.09%, and the intraday spike through 5.15% on Oct 14 shows how little a hot print needs to push it over. Hawkish Fed pricing, record-weak auction demand and bearish forecaster revisions give several dated catalysts (Oct 15 PPI, Oct 27 auction, Oct 28 and Dec 9 FOMC) before year-end. NOT FOUND: Any Treasury par-curve 5 Yr close at or above 5.10% in 2026. The Oct 15 close, since Treasury had not published it. Sibling-strike or other-venue prices for 5Y yield markets. A Q4 forecast for the 5Y from a major bank. The Trading Economics page claiming a 5.11% 5Y on Oct 14 conflicts with Treasury's 5.00% close, so I treated it as an intraday quote.
report: no case
YES means: the Treasury Daily Par Yield Curve "5 Yr" column prints 5.10% or higher on any business day from Sept 3 to Dec 31, 2026. - [2026-10-14] The intraday spike failed to carry into the close. After the hot CPI the 5-year briefly topped 5.15%, a level not seen since 2007, then Treasuries recovered most of the losses. Treasury's par close is a single end-of-day print, so a spike like this doesn't count. The 2-year ended flat at 4.80% after a 15bp spike. Sources: https://marketindex.com.au/news/asx-200-live-today-thursday-15th-october and https://www.bloomberg.com/news/articles/2026-10-14/us-treasuries-slump-as-hot-inflation-lifts-fed-rate-hike-bets - [2026-10-14] The 5-year is not reliably above the Oct 13 par close. Trading Economics shows the 5-year at 5.01% on Oct 14, with the 10-year flat at 5.22%. This conflicts with the 5.05% aggregator figure in the earlier report, so the Oct 14 level is 5.01–5.05%. Even a hot CPI day gave no closing breach. Source: https://tradingeconomics.com/united-states/government-bond-yield - [2026-10-14] The CPI shock has already faded. October hike odds fell from a peak above 50% to about 33–40% by late afternoon. Tightening priced through January fell from over 50bp to about 40bp. A large "bad-news" print has been absorbed, so the next hawkish catalyst needs to be bigger. Sources: https://ph.investing.com/news/stock-market-news/us-treasury-yields-fall-after-reversing-inflationled-selloff-93CH-2629033 and https://marketindex.com.au/news/asx-200-live-today-thursday-15th-october - [2026-10-14] Fed officials are leaning against more tightening. Williams sees no need for hikes beyond one more this year, and Jefferson and Bowman want more time. Citigroup added a December hike but still expects cuts in 2027. A peak-policy narrative caps the 5-year, which prices the average policy rate over five years.

The September projections show one more hike this year and none in 2027. 16 of 18 officials expect another increase. Officials stressed there is no need to rush. If the Oct 28 and Dec 9 meetings deliver only that one hike, the 5-year may have already priced it.

Staff did link part of the surge to buyback uncertainty. Any clarity could remove that premium.

The Nasdaq fell about 1.8%, the chip rout reached a sixth session, and AI credit stress spread to CoreWeave bonds (CoreWeave down about 15%). Haven demand and growth fears have capped the post-CPI yield rise.

The closes were 5.09% on Sep 30 and 5.06% on Oct 2 and Oct 5. A 5.09% close was followed by 5.01% (−8bp) on Oct 1. The Oct 14 intraday 5.15% did not close at 5.10%. The 5-year has repeatedly failed at 5.06–5.09%. The Oct 13 par curve was 5.00%. Source: https://stockmarketwatch.com/bonds/5-year-treasury-yield (fetched) - [2026-10-13] The 5-year par yield sits below the 7-year and 10-year (5.11% and 5.21%). A bear-steepening shape means much of the selloff sits in the long end. The 2-year, 3-year, and 5-year closes (4.79%, 4.90%, 5.00%) are tied to the front-end hike path. That path is where the central bank is pushing back. Source: https://stockmarketwatch.com/bonds/5-year-treasury-yield (fetched) - [2026-10-14] The 52-week-high clustering (5.09% close vs 5.14–5.15% intraday) shows the market has tested the strike zone about three times and each time reversed before the Treasury's close. Intraday highs near 5.14–5.15% do not satisfy the contract, which uses Treasury's par column. The par curve and H.15 constant-maturity series are both published from the same close.

It must show 5.10 or higher. A rounded 5.09 does not count, as Sep 30's did not. The only practical route to Yes is a genuine close at or above 5.10%. Source: https://polymarket.com/event/how-high-will-5-year-treasury-yield-go-before-2027 - [2026-10-14] Fwdbonds' Rupkey said the Fed may need to hike higher and hold longer in 2027. That is the main case for Yes: it would need a further 10bp or more on a close. Source: https://www.cnbc.com/2026/10/14/us-treasury-yields-cpi-inflation-report.html BOTTOM LINE: The best No case is that 5.10% has been tested at least three times (Sep 30, Oct 2, Oct 14) and each time failed on the daily close. The Fed's own projections and speakers point to one more hike, not a sustained tightening cycle, and risk-off episodes pull yields back. The weakness of this case is that the strike is only 5–10bp away with 54 trading days left and a Dec 9 FOMC still to come. NOT FOUND: Treasury's own table rows for Oct 14 (Oct 14 par close is 5.00–5.05% across aggregators), any par close at or above 5.10%, any dated Oct 15 close, and any scheduled catalyst list after Oct 15.

(0) Not yet met: Treasury's par-curve CSV shows a window high of 5.09% (Sep 30) and 5.00% on Oct 13-14; intraday spikes above 5.10% don't count. (a) About 54 trading days remain to Dec 31. (b) Status quo at 5.00% is No, but the strike is only 10bp away. (c) No: the CPI shock fades, Fed speakers cap the hike path, and risk-off from chip/AI credit stress pulls yields down, leaving repeated failures at 5.06-5.09%. (d) Yes: hot PPI or jobs data, a weak Oct 27 5-year auction, or a hawkish Oct 28 or Dec 9 FOMC pushes one close to 5.10%+. With realized vol near 5-7bp a day, a zero-drift first-passage estimate for a 10bp barrier is about 80%, trimmed slightly for discrete closes. That is consistent with the Polymarket anchor of 76%, so I stay near the market.

(0) Not yet resolved. The Treasury par-curve CSV, which is the resolution source, shows the 2026 5 Yr closing high at 5.09% on Sep 30. The latest readings are 5.00% on Oct 13 and Oct 14. Intraday highs of 5.135–5.15% on Oct 1 and Oct 14 do not count, because only the daily par close matters. (a) About 2.5 months remain, roughly 54 trading days, through Dec 31. (b) If nothing changes, the yield sits about 10bp under the strike and the market resolves No. Realized volatility of 5–8bp a day makes that unlikely to persist. A simple first-passage estimate (about 6.5bp daily vol, a discrete-close correction, no drift) gives roughly a 75–80% chance of at least one close at or above 5.10%. (c) NO path: the CPI shock fades, Fed officials (Williams, Jefferson) signal one hike and then a peak, and risk-off from the chip and AI-credit stress pulls front-end yields down. The 5Y would then keep failing at 5.06–5.09%, as it did three times recently. (d) YES path: several catalysts could push a close through 5.10%. These include a hot PPI or retail print, a tail at the Oct 27 5-year auction (the September auction was the weakest since 2018), an Oct 28 hike or a hawkish signal, the Nov jobs and CPI data, a Dec 9 dot plot showing 2027 hikes, or a renewed global term-premium selloff. The Polymarket price of about 76% (bid 72 / ask 80) matches my model estimate, and I found no unpriced information that justifies moving away from it materially.
