final rationale
Mean of 5 draws (0.55, 0.55, 0.55, 0.56, 0.58). (0) Not resolved. The market settles on the Dec 31, 2026 value. FRED DGS10 last printed 5.11% (Sep 23), and trackers show about 5.19–5.20% on Sep 24–25, so the yield sits right at the 5.14% line, perhaps 5bp above it. (a) About 3 months, roughly 65 trading days, remain, with FOMC meetings on Oct 28 and Dec 9. (b) Status quo: if today's ~5.19% held, Yes would win, but only by a few basis points. Against this, the yield rose about 50bp in five weeks, and at ~6–7bp daily volatility the three-month standard deviation is about 50–60bp, so the outcome is close to a coin flip centred slightly on Yes. (c) No scenario: oil retreats on a US–Iran deal, a softer PMI or inflation print, or the Fed skips October. Yields then mean-revert toward the 4.75–5.0% forecasts (TradingEconomics model, HSBC 4.65%), much like the 2023 spike-and-fade. (d) Yes scenario: the Fed hikes again in October and/or December, the term premium stays at its highest since 2011, supply pressure persists and Brent stays above $100. The yield then holds or extends above 5.2%, consistent with Polymarket's 92% odds of touching 5.2% before 2027. The Kalshi anchor is 60%, having risen sharply with momentum. I shade slightly below it because forecaster consensus leans toward reversion, the threshold sits at the top of the 52-week range, and sources disagree on the current level (FRED 5.11 vs ~5.20 elsewhere).

Planner reasoning
The question turns on where the 10Y yield sits now compared with 5.14%, about 3 months out. FRED DGS10 gives the current level and recent path, and the Fed funds rate and breakevens add context. The Kalshi ladder for the same event and related Fed markets give the crowd's distribution, and code_execution can turn the returned yield history into a volatility-based probability.

- current state: As of Sept 25, 2026 the 10-year Treasury yield is trading around 5.1%–5.2% (per most trackers, ~5.19-5.20%), already essentially at or just above the 5.14/5.15% threshold, driven by a hawkish Fed under Chair Warsh (first hike since 2023 on Sept 16, with markets pricing 60-70% odds of another hike at the Oct 27-28 meeting and a real chance of a further move at the Dec 8-9 meeting), persistent above-target inflation, resilient economic data, and elevated oil prices tied to US-Iran tensions.

BOTTOM LINE: As of Sept 25, 2026 the 10-year Treasury yield is trading around 5.1%–5.2% (per most trackers, ~5.19-5.20%), already essentially at or just above the 5.14/5.15% threshold, driven by a hawkish Fed under Chair Warsh (first hike since 2023 on Sept 16, with markets pricing 60-70% odds of another hike at the Oct 27-28 meeting and a real chance of a further move at the Dec 8-9 meeting), persistent above-target inflation, resilient economic data, and elevated oil prices tied to US-Iran tensions. With two more FOMC decisions before year-end and yields already flirting with 19-year highs, the current trajectory is consistent with the yield staying above 5.14% through Dec 31, though day-to-day dispersion between data sources (e.g., Forbes showing 4.96% vs TradingEconomics/MacroMicro showing ~5.2%) underscores meaningful measurement/source uncertainty right at the threshold.

report: base rate
- [2026-09-25] The 10-year Treasury yield stood at 5.19–5.20%, "remaining near its highest level since 2007," already above the 5.14% threshold as of the question's writing date. https://tradingeconomics.com/united-states/government-bond-yield
- [2026-09-14] The 10-year yield first crossed 5% intraday this cycle; CNN noted this was
"the highest level since October 2023 and just a whisker away from its highest level since 2007, which was the last time the 10-year yield rose firmly above 5%."
This establishes the reference class: sustained readings above 5% (let alone 5.14%+) have occurred in only two short windows in the last ~19 years (briefly in Oct 2023, and now in Sept 2026), versus none from 2008–2022.
- [2026-09-22] Fortune's historical review states that in
October 2023, the yield crossed 5% intraday. But it did not stay there—the yield fell as investors anticipated that inflation would drop and the Fed would begin cutting rates
, illustrating that prior touches above 5% were not durable and reversed within weeks to months.
- [2026-09-25] A separate data tracker reports the current reading is
"Higher than all but 30 of 5000 readings since 2006-09-20... Last at or above this level on 2007-07-19"
— underscoring how statistically rare a 5.14%+ close has been over the last two decades (roughly 0.6% of trading days in that 20-year sample).
- [2026-09-24] The article notes the last comparable durable break above 5% was in 2007, and only surpassed briefly in 2023, reinforcing that levels above 5.14% are historically an outlier "regime," not the base-rate norm, though the current cycle has now produced one.
- [2026-09-24] Momentum/analyst commentary is currently hawkish: markets were
"pricing nearly a 64% chance of another 25 bps rate hike in October and more than a 48% probability of a similar move in December"
, suggesting near-term upward pressure rather than reversion.
- [2026-09-16] The Fed already delivered
its first hike in three years, taking its overnight lending rate to a 3.75%-4% range, up from 3.5%-3.75%
, a genuine regime shift versus the 2023 episode (when the Fed was near a cutting cycle), which differentiates this run from the prior false break above 5%.
- [2026-09-07] Despite the current spike, professional forecasters' year-end 2026 point estimates are generally below 5.14%: HSBC's revised, more-hawkish forecast raised its
"end-2026 forecast for the 10-year Treasury yield to 4.65% from 4.30%, citing a higher structural floor under long-term yields and a more hawkish distribution of potential monetary-policy outcomes."
- [2025-11-13] Transamerica's 2026 outlook (pre-dating the current spike) projected an even lower year-end figure, forecasting a
"10-year U.S. Treasury bond yield of 3.75%"
for year-end 2026 — since badly overtaken by events, illustrating how quickly base-rate/consensus forecasts have been invalidated this cycle.
- [2026-09-25] Trading Economics' own quantitative model, despite acknowledging the yield is now at 5.20%, still forecasts reversion, estimating the yield
"is expected to trade at 4.99 percent by the end of this quarter... we estimate it to trade at 4.75 in 12 months time."
This is a "mean-reversion" base rate view common among institutional models, standing in tension with current market momentum.
- [2026-07-23] An algorithmic/statistical extrapolation site (longforecast) projected the 10-Year ending December 2026 at roughly 4.96%, with a monthly range up to about 5.26%, i.e., below the 5.14% bar under its baseline path.
- NOT FOUND: No direct current Kalshi/other prediction-market implied probability specifically for the "above 5.14% on Dec 31, 2026" contract could be retrieved (the Kalshi tag/market pages loaded without visible odds data); no long-run (multi-decade) systematic base-rate study quantifying the historical frequency of >5.14% year-end closes was found.
BOTTOM LINE: Historically, closes above ~5.14% have been extremely rare over the last two decades (essentially absent between 2007 and 2023, with only a brief 2023 intraday touch), making a "high yield regime" a low base-rate event; however, the current cycle has already broken that pattern with the yield sitting well above 5.14% today, so the outside-view "reversion to norm" argument used by several institutional forecasters (HSBC 4.65%, Transamerica 3.75%, TradingEconomics model 4.75%) cuts against, not for, sustained YES resolution, while raw momentum/base-rate-of-recent-days argues the opposite.

- [2026-08-17] Barclays attributes the move to structural fiscal/supply forces rather than data surprises:
strategists at Barclays see the rise in rates less about inflation and more about the U.S. budget deficit, high levels of issuance related to artificial intelligence competing with Treasurys, and higher term premiums... "Three independent releases argued for lower yields this month; long end yields moved higher anyway."
This "yields rise despite soft data" pattern suggests resilience of the YES path even if incoming data softens somewhat before year-end. Source: https://www.cnbc.com/2026/08/17/treasury-yields-federal-reserve-fomc-minutes.html
- [2026-08-18] BMO's Ian Lyngen frames the near-term trajectory explicitly upward:
"a record pace of corporate bond issuance has added substantial duration supply to U.S. fixed income markets... The path of least resistance will likely favor higher long-end rates in the near-term unless there is a slowdown in the market supply of duration, sharp tightening of financial conditions or dimming of the economic outlook."
None of those reversal conditions (supply slowdown, financial tightening, economic dimming) has materialized as of late September. Source: https://www.cnbc.com/2026/08/18/us-government-debt-yields-are-surging-at-a-bad-time-heres-whats-behind-the-move.html

"Markets are increasingly pricing a prolonged Mideast conflict."
A further oil spike is a concrete near-term mechanism that could push the 10-year decisively and durably above 5.14% via both breakeven inflation and Fed-hawkishness channels. Source: https://www.cnbc.com/2026/09/08/oil-prices-today-brent-wti-hormuz-iran-war.html
BOTTOM LINE: The strongest YES case rests less on momentum alone and more on structural mechanisms — a term premium at its highest since 2011 reflecting fiscal/supply pressures, near-unanimous hawkish repricing of Fed hikes (October probability jumped from ~7% to ~58% in one month per the NY Fed-based analysis), and an unresolved US-Iran conflict that has already driven a 17% September oil spike and could reintensify — all of which are durable, ongoing forces (not one-off data prints) that could keep the 10-year above 5.14% through Dec 31, with two more FOMC meetings (Oct 27-28, Dec 8-9) as concrete near-term catalysts.
NOT FOUND: A current, dated CME FedWatch or Fed funds futures probability specifically for the December 8-9 meeting (only stale/incomplete tool pages were retrievable); no explicit statement of Kalshi's exact settlement data source (FRED DGS10 vs. other) for the Dec 31 resolution.
report: no case
- [2026-08-19] As recently as five weeks before today's snapshot, the 10-year sat at roughly 4.70%, "a 19-month high," meaning the run to ~5.20% represents a ~50bp move in about five weeks — a pace of change that argues the current level could reverse just as quickly if data or geopolitics turn. https://cryptobriefing.com/us-10-year-treasury-yield-5-percent-2026/
- [2026-08-19] A Reuters poll from that month
showed a median 10-year yield forecast of 4.50% over a three-month horizon
— a professional-forecaster median roughly 65bp below the 5.14% threshold for a period bridging into Q4 2026, even though
82% of the strategists surveyed flagged upside risks to that estimate
.
- [2026-07-17] Morgan Stanley Research's house view was that
markets are pricing at least one 2026 rate hike, but the Fed would stay on hold as inflation moderates, supporting Treasuries and high-quality fixed income
, with economist Michael Gapen expecting
"a lower inflation trajectory that keeps policy on hold this year, potentially followed by two rate cuts in 2027 as inflation gradually normalizes."
- [2026-08-17] Just weeks before the September hike materialized, Goldman Sachs argued a hike was "very unlikely," with chief economist Jan Hatzius stating
"We still think market pricing for the funds rate is too hawkish,"
and the bank
predicting the Fed would hold the federal funds target range at 3.50%-3.75% through the remainder of 2026, with any rate cuts postponed to 2027
— illustrating that even sophisticated desks have repeatedly underestimated Fed hawkishness this cycle, a bias that could just as easily flip toward over-hawkishness now.
- [2026-08-17] At that same moment, Polymarket's own rate-hike-in-2026 contract showed
prediction markets leaning toward 'No' bets on the Federal Reserve raising interest rates at least once in 2026, with Polymarket data showing No bets at 53% while Yes traded at 47%
, and the
10-year US Treasury yield had dropped to 4.676%
that day — a reminder that the "hawkish regime" narrative is only a few weeks old and was not the consensus base case as recently as mid-August.
- [2026-09-23] CNN's account of the latest surge notes it was triggered by a specific, reversible data catalyst:
business activity in September accelerated at the fastest rate since July 2021, according to data from S&P Global, while input costs surged because of the rise in energy prices
— a single strong PMI print and an oil spike, not a structural re-rating, meaning a softer PMI or oil pullback could unwind much of the move.
- [2026-09-23] The same report shows the threshold itself was already tested and rejected once:
the 10-year yield topped 5% earlier this month before pulling back in recent days – and then surging on Wednesday above 5.1%... the yield rose as high as 5.14% during trading before settling at 5.11%
, i.e., an intraday touch of exactly 5.14% failed to hold into the close, the same pattern (spike-then-fade) that defined the 2023 episode.
- [2026-09-25] Yahoo/CBOE quote data (^TNX) shows the 52-week trading range as
Day's Range · 4.98 - 5.13 · 52 Week Range · 3.95 - 5.14
, meaning 5.14% has literally been the ceiling of the entire past year — the "above 5.15%" bar sits exactly at the outer edge of the 52-week range, not comfortably inside a new higher regime.
- [2025-12-17] The St. Louis Fed's own review of forecaster track records found a persistent bias:
the MFE 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 what materializes — a systematic historical tendency toward over-hawkish yield calls that, if it recurs, would pull a ~5.20% current print back under 5.14% by year-end.
- [2026-07-23] An independent statistical/algorithmic model's most recent monthly path (pre-dating the September Fed hike but illustrating the reversion scenario still in play) put
the 10-Year Treasury Yield at the end of December at 4.963%, change for December -0.233 points
from a November starting point above 5.1%, i.e., a modeled pullback of roughly 20bp+ into year-end that would land below the 5.14% bar.
- [2026-09-25] Working against the NO case, a related Kalshi interest-rate market snapshot showed a "5.15% or below" outcome priced at only about 1% implied probability, suggesting the broader Kalshi market currently leans heavily toward the yield staying above, not below, this threshold — a fact any NO argument must contend with rather than dismiss.
BOTTOM LINE: The NO case rests on the speed and narrowness of the current breakout — the 10-year rallied roughly 50bp in five weeks off a single PMI/oil shock, touched exactly 5.14% intraday before fading, and sits at the very top of its 52-week range — combined with a Reuters poll median (4.50%), Morgan Stanley's on-hold Fed call, and long-run forecaster over-hawkishness bias, all of which point to reversion below 5.14% by Dec 31; but this case is undercut by same-day Kalshi pricing that implies the market itself assigns only ~1% probability to the yield closing at or below roughly 5.15%.
NOT FOUND: A direct, current Kalshi order-book screenshot or quote for the specific "above 5.14% on Dec 31, 2026" contract (only an adjacent-looking "5.15% or below" market snippet was recoverable); no explicit confirmation of which yield series (DGS10 close vs. intraday vs. Treasury par curve) Kalshi will use to settle, which matters given the source-to-source dispersion already noted (e.g., Forbes' 4.96% vs. TradingEconomics' 5.20% same-week readings).

(0) Not resolved. The market settles on the Dec 31, 2026 value. FRED DGS10 last printed 5.11% (Sep 23), and trackers show about 5.19–5.20% on Sep 24–25, so the yield sits right at the 5.14% line, perhaps 5bp above it. (a) About 3 months, roughly 65 trading days, remain, with FOMC meetings on Oct 28 and Dec 9. (b) Status quo: if today's ~5.19% held, Yes would win, but only by a few basis points. Against this, the yield rose about 50bp in five weeks, and at ~6–7bp daily volatility the three-month standard deviation is about 50–60bp, so the outcome is close to a coin flip centred slightly on Yes. (c) No scenario: oil retreats on a US–Iran deal, a softer PMI or inflation print, or the Fed skips October. Yields then mean-revert toward the 4.75–5.0% forecasts (TradingEconomics model, HSBC 4.65%), much like the 2023 spike-and-fade. (d) Yes scenario: the Fed hikes again in October and/or December, the term premium stays at its highest since 2011, supply pressure persists and Brent stays above $100. The yield then holds or extends above 5.2%, consistent with Polymarket's 92% odds of touching 5.2% before 2027. The Kalshi anchor is 60%, having risen sharply with momentum. I shade slightly below it because forecaster consensus leans toward reversion, the threshold sits at the top of the 52-week range, and sources disagree on the current level (FRED 5.11 vs ~5.20 elsewhere).

(0) Not resolved: FRED DGS10, the likely settlement series, printed 5.11% on Sep 23, just below the 5.14% line. TradingEconomics and MacroMicro report about 5.19–5.20% on Sep 24–25. Yahoo's ^TNX shows a day range topping out at 5.13% and a 52-week high of 5.14%. So the current level sits right at the threshold, and exactly where is uncertain. (a) About three months (~65 trading days) remain until the Dec 31 close. (b) Status quo: if yields hold at today's roughly 5.11–5.20%, the outcome is near a coin flip that leans YES. At 5–7 bps of daily volatility, the spread of outcomes by year-end is about ±50bp, so the starting point matters less than the drift. (c) NO: the ~50bp September spike, driven by an oil shock and a strong PMI, fades. That could come from Iran de-escalation, softer inflation or data, or the Fed pausing after one hike. Mean-reversion forecasts (TE model 4.75–4.99%, HSBC 4.65%, Reuters poll median 4.50%) and the 2023 spike-then-fade precedent support this path. (d) YES: the Fed hikes again in October and/or December (markets price ~60–67% for October and ~48% for December). The term premium is at its highest since 2011, supply is heavy, Brent is above $100, and the yield holds or grinds higher. Kalshi at 60% is my anchor; Polymarket's 5.2% touch market at 92% is related context only. The hawkish momentum is real, but the resolution-source value is still below the line and institutional models expect reversion, so I shade slightly under the market to 0.55.

(0) Not resolved. The market settles on the Dec 31, 2026 value. FRED DGS10 read 5.11% on 9/23, just below 5.14%. TradingEconomics and MacroMicro show about 5.19–5.20% on 9/24–9/25, so the yield now sits a few basis points above the threshold, though sources disagree by several bps. (a) About 3 months, roughly 65 trading days, remain, including the Oct 28 and Dec 9 FOMC decisions. (b) Status quo: if yields hold near 5.19–5.20%, the market resolves Yes, but only by a thin ~5bp cushion. In this volatile regime (6–7bp/day), the 3-month standard deviation is about 50–60bp, so with zero drift the outcome is close to a coin flip slightly tilted to Yes (~53%). (c) NO: the oil spike from the US-Iran conflict eases, PMI and inflation data soften, the Fed hikes once more and signals a pause, and mean reversion (TradingEconomics model 4.75%, HSBC 4.65% year-end) pulls the 10Y back to 4.9–5.1%, much as the Oct 2023 break above 5% faded. (d) YES: a term premium at its highest since 2011, heavy issuance, markets pricing a 60–70% chance of an October hike and about 48% for December, and Brent above $100 keep the 10Y at 5.2–5.5%. Polymarket prices a touch of 5.5% before 2027 at about 29%. The Kalshi anchor is 60% after a sharp momentum-driven jump. I shade slightly below it for mean-reversion evidence and the forecasters' track record, landing at about 55%.

(0) The condition is not already resolved: FRED DGS10, identified by the resolution-source read as the matching series, was 5.11% on September 23, below 5.15%, so it must print at least 5.15% on December 31. (a) About 97 days remain until the December 31 close, including October and December FOMC decisions. (b) If the latest official level simply persists, the market resolves No, although same-day market trackers around 5.19%-5.20% indicate it may already have moved above the threshold since FRED's latest observation. (c) A No scenario is that oil prices retreat, economic data soften, and the recent roughly 50-basis-point surge mean-reverts toward forecasts such as HSBC's 4.65% or Trading Economics' 4.99% quarter-end estimate. (d) A Yes scenario is that another Fed hike, persistent inflation, heavy Treasury supply, and a term premium near its highest since 2011 keep the yield above 5.14% through year-end. I anchor on Kalshi's 60% Yes price but reduce it to 56% because this is a single-date close rather than an intraperiod touch, the official series remains just below the line, and historical 5% breakouts have often reversed; the recent hawkish regime and structural supply pressures prevent a larger downgrade.

(0) The condition is not already resolved: FRED DGS10, identified by the resolution-source read as the matching series, was 5.11% on September 23, below 5.14%, while the required December 31 observation has not occurred. (a) About 97 days remain until the December 31, 2026 close, including two scheduled FOMC decisions on October 28 and December 9. (b) If the latest official FRED value simply persisted, the market would resolve No, although September 24-25 market trackers put the live yield near 5.19%-5.20%, slightly above the threshold. (c) A No scenario is that oil and geopolitical pressures ease or economic data soften, reversing part of the roughly 50-basis-point five-week surge and producing the mean reversion anticipated by HSBC's 4.65% forecast and Trading Economics' 4.99% quarter-end model. (d) A Yes scenario is that another Fed hike, persistent inflation, heavy Treasury supply, and the term premium near its highest since 2011 keep the yield in its new 5%+ regime through year-end. I anchor on Kalshi's 60% Yes price and trim it to 58% because the threshold is extremely close, the official series still lagged below it, and several forecasts expect reversion, while the recent hawkish regime shift and structural supply pressures prevent a larger downward adjustment.
