final rationale
Mean of 4 draws (0.11, 0.13, 0.13, 0.12). (0) Not met: the FRED DFEDTARU series shows the upper bound at 4.00% as of 2026-10-03 after the Sept 16 hike, so ≥4.50% needs 50bp more via hikes at both the Oct 27-28 and Dec 8-9 meetings, or a 50bp single move. (a) About 9-10 weeks and two scheduled FOMC decisions remain. (b) Status quo is 4.00%, which resolves NO; the modal path is one December hike to 4.25% (September median dot, Williams' 'one further upward adjustment late this year', Jefferson's 'no urgency'), also NO. (c) NO: October hold confirmed (October hike odds fell from ~70% to ~18-23% after Williams; weak +29K payrolls), then 25bp or nothing in December. (d) YES: hot inflation nowcasts (core PCE ~3%, Q4 CPI pace ~4%) and Logan's push for 50bp+ lead the FOMC to override troika guidance and hike in October and again in December, or less likely jump 50bp in December. Rough math: P(Oct hike) ~0.2 x P(Dec hike given Oct hike) ~0.5 ≈ 0.10, plus ~0.01-0.02 for a 50bp move, giving ~11%, slightly under the Polymarket anchor of 12.7% (bid/ask 12/14), which has already repriced sharply this week; no strong edge.

Planner reasoning
This is a Polymarket Fed-rate question, so polymarket_direct is the price anchor and resolution_source checks the current target range on the Fed's FOMC page. FRED supplies the current effective rate and the target range bounds, plus inflation and unemployment data. Kalshi's KXFED and FOMC decision markets give an independent crowd price for the same year-end outcome.

report: current state
- [2026-09-16] The FOMC raised the target federal funds range by 25 bps to 3.75%–4.00% (upper bound 4.00%), its first hike since 2023, approved by a 12–0 vote. https://www.federalreserve.gov/newsevents/pressreleases/monetary20260916a.htm - [2026-09-16] The Committee's statement said Inflation remains elevated. Today's policy action will support a timelier return to the Committee's 2 percent goal. https://www.federalreserve.gov/newsevents/pressreleases/monetary20260916a.htm - [2026-09-16] September Summary of Economic Projections: the median participant now expects the fed funds rate to hike an additional 25bps ending 2026 at 4.1%, no change to the policy rate in 2027. Sixteen of eighteen participants expect one additional rate hike this year, while four participants project two additional hikes. The most hawkish dot sees the policy rate at 4.375% in 2026 and 2027 , implying the committee's own median path points to an upper bound of 4.25% by year-end, not 4.50%. https://am.jpmorgan.com/us/en/asset-management/adv/insights/portfolio-insights/fixed-income/fixed-income-perspectives/fomc-statement-september-2026/ - [2026-10-02] FRED's official daily series shows the Federal Funds Target Range – Upper Limit at 4.00% as of October 2, 2026 (unchanged since the September hike). https://fred.stlouisfed.org/series/DFEDTARU - [2026-10-02] The effective federal funds rate (EFFR) was 3.88% as of October 1, 2026, consistent with the 3.75–4.00% target range. https://www.federalreserve.gov/releases/h15/ - [2026-10-04] The Federal Reserve's official calendar confirms the two remaining scheduled 2026 meetings are October 27–28 and December 8–9 (the latter carrying a Summary of Economic Projections). https://www.federalreserve.gov/monetarypolicy/fomccalendars.htm - [2026-08-31] Ahead of the September meeting, CME FedWatch showed Federal Reserve officials are likely to hike the federal funds rate by 25 basis points at their September meeting, with the CME FedWatch Tool showing a 66% probability... with the PCE index at 3.7% and 4.1% over 12 and 6 months respectively, well above the 2% target , and Barclays anticipates two more rate hikes this year, in September and December, totaling 50 basis points. That Barclays path (Sept +25, Dec +25) would land the upper bound at exactly 4.25%, not 4.50%. https://www.forbes.com/sites/digital-assets/2026/08/31/cme-fedwatch-provides-a-66-chance-fed-will-hike-rates-in-september/ - [2026-08-07] Earlier in the cycle, after a weak July jobs report, CME's FedWatch tool still sees a 55% chance of a hike in October, and an almost 75% chance in December , indicating the market was pricing possible hikes at both remaining meetings (consistent with a path toward 4.25%–4.50%, but this data predates the September hike itself and is now stale). https://www.cnbc.com/2026/08/07/odds-the-fed-hikes-in-september-tumble-following-big-july-jobs-miss.html - [2026-10-01] An independent futures-based tracker estimated the market-implied odds for the December 9, 2026 meeting at roughly 79% probability of a higher rate than today's level (cumulative, i.e., including any October move), equivalent to roughly +20 bps expected — consistent with one more 25bp hike priced in by year-end rather than two. (Note: page's own "age" metadata appears stale/cached, so treat as indicative only.) https://centralbank.watch/federal-reserve/ - [2026-10-01] A separate futures-based rate forecast estimated futures markets are pricing the rate to rise to about 4.1% by January and reach roughly 4.7% by October 2027 , again implying a single additional 25bp move (to ~4.25% upper bound) by year-end 2026, with further tightening expected to continue into 2027 rather than being front-loaded to December 2026. https://streetstats.finance/rates/fedfunds - [2026-10-04] No FOMC meeting has occurred since September 16, 2026; the October 27–28 and December 8–9 meetings remain the only two scheduled rate decisions before the question's resolution deadline. BOTTOM LINE: The target range currently sits at 3.75%–4.00% (upper bound 4.00%) after the September 2026 hike, with the Fed's own dot plot and most market-based measures pointing to roughly one more 25bp hike by year-end (to 4.25%), not two. Reaching an upper bound of 4.50% by the Dec 8-9 meeting (or by Dec 31) would require back-to-back 25bp hikes at both the October and December meetings, which is a more aggressive path than the median SEP dot or current futures pricing implies, though not inconsistent with the most hawkish committee projections or periods of market pricing seen over the summer. NOT FOUND: A live, dated CME FedWatch Tool snapshot specifically for the October 28 and December 9, 2026 meetings as of early October 2026 (most recent concrete probabilities found were from August 2026, now likely stale); no evidence of any unscheduled/emergency FOMC meeting since September 16, 2026.
report: base rate
- [2026-09-16] The FOMC unanimously voted 12-0 to raise the federal funds rate 25bp, taking the target range from 3.50%-3.75% to **3.75%-4.00%** — the Committee decided to raise the target range for the federal funds rate by 1/4 percentage point to 3-3/4 to 4 percent, in support of the Federal Reserve's dual mandate . This was the first hike since 2023, reversing three 2025 cuts. - [2026-09-16] The accompanying dot plot shows a median year-end-2026 projection of only one more hike: the median participant now expects the fed funds rate to hike an additional 25bps ending 2026 at 4.1% , which rounds to an upper bound of 4.25% — below the 4.5% threshold in this question. - [2026-09-16] Only a minority of officials see enough tightening to reach 4.5% upper bound by year end: Fed officials' year-end rate projections are between 4.1% and 4.4% , and the most hawkish participant sees the policy rate at 4.375% in 2026 and 2027 (i.e., a 4.25%-4.50% range, just touching the 4.5% upper-bound threshold as the hawkish outlier, not the median). - [2026-09-16] Breadth of hike support: sixteen of eighteen participants expect one additional rate hike this year, while four participants project two additional hikes — meaning only ~22% of the Committee explicitly projects the two hikes needed to push the upper bound to 4.50% or higher. - [2026-09-23] Market pricing shifted hawkish after Governor Barr's comments and a hot inflation print: markets priced in a better than 70% chance that the Federal Reserve will approve another interest rate hike when it meets next in October... The odds of a rate hike when the Federal Open Market Committee meets again Oct. 27-28 jumped to 73%, according to the CME's FedWatch . - [2026-10-01] That hawkish pricing reversed quickly: Investing.com's Fed Rate Monitor as of Oct 1 showed the October 28 meeting pricing **77.0%** probability of a hold at 3.75%-4.00% versus 23.0% for a hike to 4.00%-4.25%. - [2026-10-03] Prediction-market odds (Kalshi/Polymarket) corroborate a sharp dovish repricing for October specifically, while year-end hike odds remain high: the DeFi Rate aggregator shows an October 28 hike priced at just **18%** (hold 83%), down 45 points in a week, while the probability of **"another hike before 2027"** stands at **73%**, with the **December 9** meeting alone priced at **72%** for a hike. - [2026-10-03] Critically, these venues price only a single additional hike as the base case for 2026, not two: the same source states "at least one more hike this year is the base case," and the meeting-by-meeting path shows October (20% hike) and December (73% hike) as the two remaining chances — consistent with one hike (to 4.00%-4.25%, upper bound 4.25%) being the modal outcome, not two hikes to 4.50%. - [2026-10-02] Official Fed data (FRED) confirm the current standing target range: 2026-10-02: 4.00 for the upper limit, i.e., the starting point from which two more 25bp moves (or one 50bp move) would be needed to reach 4.50% by December. - [2026-10-01] A separate market-implied rate-path tracker pegged the effective funds rate at 3.88% and saw it rising to about 4.1% by January and reaching roughly 4.7% by October 2027 — implying the bulk of tightening priced in by markets is expected to unfold gradually through 2027, not concentrated by December 2026. - [2026-10-01] One Fed official (Dallas Fed's Logan) has publicly called for more aggressive action, reportedly saying "50 bps or more" of hikes are needed to curb inflation, per Investing.com's Fed Rate Monitor commentary — but this is a single hawkish voice, not the Committee's median view. - [Historical context] Reaching the 4.5% threshold requires the Fed to deliver two 25bp hikes (or equivalent) in the roughly three months between now and December 9 — a pace of tightening (50bp in one quarter) that, in the post-2023 easing-then-reversal environment, has no precedent yet in this hiking cycle, which began with single 25bp moves. BOTTOM LINE: The base/outside-view case is modestly against this resolving YES: the Fed's own September dot plot and current market/prediction-market pricing both center on just one more 25bp hike in 2026 (upper bound to 4.25%), with only a hawkish minority of officials (4 of 18) and no clear market consensus pricing two hikes (to 4.50%) by the December meeting; reaching ≥4.50% would require incremental hawkish surprises (e.g., sustained inflation acceleration or a 50bp move) beyond what is currently the modal forecast. NOT FOUND: A clean historical base rate for "how often the Fed delivers two tightening moves within one quarter after resuming hikes" (no directly comparable past episode was identified); a specific Polymarket/Kalshi-quoted probability for "upper bound ≥4.50% at year-end 2026" distinct from the single-meeting hike/hold contracts cited above.
report: yes case
YES means: the Federal Reserve raises its target federal funds range so that the upper bound stands at ≥4.50% when the December 8–9, 2026 FOMC statement is issued (or, absent a December decision, the upper bound sits at ≥4.50% as of December 31, 2026) — i.e., the Fed delivers a cumulative 50bp (two 25bp hikes, or one 50bp move) on top of the current 3.75%–4.00% range at the October 27–28 and/or December 8–9 meetings. - [2026-10-01] A sitting FOMC voter, Dallas Fed President Lorie Logan, said rates need to rise at least another 50 basis points to make monetary policy modestly restrictive and get inflation back on track toward its 2% goal, after the Fed raised its policy rate by a quarter point last month to 3.75%-4.00% , explicitly endorsing a path that would push the upper bound to 4.50%. https://rallies.ai/news/feds-logan-calls-for-50-bps-or-more-in-rate-hikes-6aeb1a19ab1e56a7 - [2026-10-02] Logan added that inflation is falling as transitory factors fade, but may not fall much below 2.5% without further rate hikes, with the economy strengthening and the labor market well balanced , and that a few more increases would simply undo the 75bp of 2025 cuts — a direct, technocratic case for two more hikes rather than one. https://www.chaincatcher.com/en/article/2293591 - [2026-10-02] Underlying inflation is reaccelerating, not cooling: the Cleveland Fed's nowcast puts September 2026 core PCE year-over-year at 3.02%, with headline PCE at 3.56% and core CPI at 2.39% , and critically projects Q4 2026 CPI running at a 4.02% annualized pace — data that, if realized, would validate hawks like Logan and Warsh ahead of the December meeting. https://www.clevelandfed.org/indicators-and-data/inflation-nowcasting - [2026-09-23] Ahead of the shutdown-driven data blackout, CME FedWatch pricing already showed a 66% likelihood that FOMC officials would increase the target range to between 375 and 400 bp for September, and separately the same tool's year-end distribution assigned a non-trivial 41.4% probability to a cumulative 50bp hike by year-end — i.e., markets have at times priced the two-hike YES path as nearly a coin-flip alongside the one-hike scenario. https://phemex.com/news/article/cme-fedwatch-542-probability-of-rate-hike-at-october-meeting-97512 - [2026-10-01] An independent futures tracker's December 9 meeting-specific probability stood at 79.4%+19.9 bp for a higher rate, which, layered on top of any October move, is consistent with the market still assigning real (if minority) odds to back-to-back hikes rather than a single move concentrated in December alone. https://centralbank.watch/federal-reserve/ - [2026-09-11] The September CPI report came in hot ahead of the September hike: CPI accelerated in August, increasing 0.29% on the month in the firmest inflation print since April, with only one monthly reading in the past twelve months consistent with the Fed's 2% target , and PNC's house view was explicitly for the Fed to raise rates by 25 basis points in September, followed by additional hikes in December and March — a multi-hike hawkish base case that, if it had included October too, would reach 4.50% by year-end. https://www.pnc.com/content/dam/pnc-com/pdf/aboutpnc/EconomicReports/EconomicUpdates/2026/PNC_Economics_Research_CPI_11_September_2026.pdf - [2026-09-27] Before the shutdown disrupted data flow, the August PPI report had been strong enough that odds of an October hike reportedly reached 100% per one aggregator, and separately Goldman Sachs "officially shifted its Federal Reserve forecast and now expects a hike in October," which combined with the already-elevated odds of a December hike would deliver the two 25bp moves needed for a 4.50% upper bound. https://www.onebullex.com/news/articles/five-data-releases-decide-if-fed-hikes-again-in-october-after-september-16-increase-5 - [2026-10-01] A government shutdown has been in effect since October 1, 2026, delaying the September/October CPI and jobs reports; a prolonged data blackout removes the disinflationary prints that would otherwise restrain hawks, leaving the Fed more reliant on anecdotal/regional-Fed signals (like Logan's) and on upside inflation nowcasts, a dynamic that historically has not prevented, and can even accelerate, hawkish policy error given political pressure to "not fly blind." https://www.onebullex.com/news/articles/five-data-releases-decide-if-fed-hikes-again-in-october-after-september-16-increase-5 - [2026-08-31] New Fed Chair Kevin Warsh has staked his credibility on inflation-fighting, with hawkish framing that the Fed's "predominant focus right now should be on prices" after flagging PCE readings well above target — a chair explicitly willing to override a merely "one more hike" median if incoming data stays hot. https://www.forbes.com/sites/digital-assets/2026/08/31/cme-fedwatch-provides-a-66-chance-fed-will-hike-rates-in-september/ - [2026-09-16] The Committee's own hawkish tail already sits at the YES threshold: the most hawkish SEP dot placed the policy rate at 4.375% for 2026 (rounding to a 4.25%-4.50% range), and four of eighteen participants explicitly projected two hikes this year — meaning the mechanism for YES (two 25bp moves) is already inside the Committee's own distribution of views, not a tail-risk scenario invented by markets. https://am.jpmorgan.com/us/en/asset-management/adv/insights/portfolio-insights/fixed-income/fixed-income-perspectives/fomc-statement-september-2026/ BOTTOM LINE: The clearest path to YES is a second 25bp hike in October (plausible given pre-shutdown PPI strength, Goldman's hawkish shift, and a hot inflation nowcast) followed by a third 25bp hike in December, a sequence openly advocated by sitting FOMC voter Logan and sitting within the hawkish tail of the Fed's own September dot plot; a prolonged shutdown-driven data vacuum could reinforce hawkish priors rather than force a pause. NOT FOUND: An official Fed communication (minutes, speech, or statement) explicitly committing to a 50bp move at a single meeting; a specific, dated CME FedWatch or Polymarket snapshot (post-October-2026) showing cumulative year-end probability of ≥4.50% as the plurality outcome.
report: no case
YES means: the upper bound of the Fed's target federal funds range is 4.50% or higher at year-end 2026 (i.e., the FOMC delivers a second 25bp hike on top of the September move — or an equivalent 50bp move — by the December 8–9 meeting, or by Dec 31 if no decision issues). - [2026-09-29] New York Fed President John Williams, vice chair of the FOMC, explicitly said Federal Reserve policymakers probably only need to deliver one more rate hike this year to get inflation back on track, saying "with the policy action we took at our September meeting, there is no need for urgency." This is the clearest leadership-level pushback yet against pricing in two more hikes. - [2026-09-29] Williams tied that single hike to December, not October: "one further upward adjustment of the federal funds target range may be appropriate late this year," and traders quickly pared bets for an October hike, instead pricing for a single interest-rate hike this year, most likely at the Fed's mid-December meeting. - [2026-10-01] Fed Vice Chair Philip Jefferson echoed the patience message on the same side of the troika: "Since our September meeting, yields across the term structure have increased further, a sign that investors are reassessing the evolving macroeconomic landscape," Jefferson said, adding "My colleagues and I will need to come to our own judgment, which may take more time." - [2026-10-02] Evercore ISI's read of this guidance was unambiguous on the mechanism relevant to this question: "the Fed does not expect to deliver a back-to-back rate hike at its coming October meeting," and "we think the joint message from Jefferson and Williams is authoritative." Ruling out an October hike removes one of the two moves needed to reach 4.50% by December. - [2026-10-02] The September payrolls report reinforced the dovish-for-October case: "US adds 29K jobs, labor demand 'flashing yellow'" — a weak print that, per the same reporting, is likely to keep the Fed on hold later this month, with the focus still on inflation rather than accelerating tightening. - [2026-10-02] Market pricing for October collapsed accordingly: "Since Williams spoke on Tuesday, market bets on an October rate hike have plummeted to 18% as of Friday morning from around 70% on Monday." A near-certain October hold removes the "double hike" path that YES requires. - [2026-10-02] Bloomberg's framing of the week's Fed communication underscores an engineered signal, not noise: Fed Vice Chair Philip Jefferson and New York Fed President John Williams said in separate speeches they believe the central bank has time to assess the economy before considering another rate increase, comments that reeled in investor expectations for a rate hike this month. - [2026-10-02] Chicago Fed's Goolsbee, while leaving the door open on the meeting itself, signaled no urgency for a faster pace either: "There is plenty of room for anything to be on the table," Goolsbee said when asked about the next meeting, while noting latest jobs data shows the labour market is steady. - [2026-09-29] Even Williams' own inflation forecast argues against a jumbo or double-hike path: "Williams sees inflation of 3.5% this year, noting that 'the inflationary impact of the AI-related demand shock is increasingly salient.'" A moderating (not accelerating) inflation path undercuts the case for two more hikes rather than one. - [2026-10-02] Only one regional president, Dallas's Logan, has staked out a position aggressive enough to be consistent with a YES outcome: Dallas Fed President Lorie Logan called last month's move a "first step" and said that at least another half of a percentage point of rate hikes would be needed to get inflation back on track to the Fed's 2% goal. This remains a minority dissenting view, not committee consensus. - [2026-10-04] Mechanically, with October now priced as an overwhelming hold (18% hike odds) and leadership guidance pointing to a single December move, the path to 4.50% requires either a reversal of the troika's just-delivered guidance plus a hike in October, or a 50bp move in December alone — neither of which is signaled by any current official communication. BOTTOM LINE: The Fed's own vice-chair-level leadership (Williams, Jefferson) has, within the last week, explicitly and deliberately talked down market pricing for an October hike and anchored expectations on exactly one more 25bp move (to 4.25% upper bound) by December, directly contradicting the two-hike path needed for this question to resolve YES; only a single hawkish dissenter (Logan) and a weak minority of the September dot plot support the 4.50% outcome. NOT FOUND: A post-October-meeting (or post-September-jobs-report) updated dot plot or SEP; any FOMC communication contemplating a 50bp single move; a dated, named-source probability specifically for "4.50% or higher by Dec 31" distinct from single-meeting hike/hold odds.

(0) Not met: the FRED DFEDTARU series shows the upper bound at 4.00% as of 2026-10-03 after the Sept 16 hike, so ≥4.50% needs 50bp more via hikes at both the Oct 27-28 and Dec 8-9 meetings, or a 50bp single move. (a) About 9-10 weeks and two scheduled FOMC decisions remain. (b) Status quo is 4.00%, which resolves NO; the modal path is one December hike to 4.25% (September median dot, Williams' 'one further upward adjustment late this year', Jefferson's 'no urgency'), also NO. (c) NO: October hold confirmed (October hike odds fell from ~70% to ~18-23% after Williams; weak +29K payrolls), then 25bp or nothing in December. (d) YES: hot inflation nowcasts (core PCE ~3%, Q4 CPI pace ~4%) and Logan's push for 50bp+ lead the FOMC to override troika guidance and hike in October and again in December, or less likely jump 50bp in December. Rough math: P(Oct hike) ~0.2 x P(Dec hike given Oct hike) ~0.5 ≈ 0.10, plus ~0.01-0.02 for a 50bp move, giving ~11%, slightly under the Polymarket anchor of 12.7% (bid/ask 12/14), which has already repriced sharply this week; no strong edge.

I retain Polymarket's live 12.7% Yes price: the research provides no verified information clearly missing from that consensus, and its recent decline already reflects the retreat in October hike expectations. No source documents the resolving December decision, so neither outcome is settled; the September 16 FOMC statement and FRED's target-upper-limit observations through October 3 corroborate a current upper bound of 4.00%. Approximately 66 days remain until the December 9 decision, with October 27–28 and December 8–9 the remaining scheduled meetings; the fallback deadline is December 31 at 11:59 PM ET, about 88 days away. If policy remains unchanged, the outcome is No at 4.00%. The principal No scenario is an October hold followed by one 25-basis-point December hike to 4.25%, consistent with the reported September 29 Williams and October 1 Jefferson patience signals, the September median projection, and indicative futures pricing. Yes requires renewed inflation pressure to produce two additional 25-basis-point hikes or one 50-basis-point move, a plausible minority path supported by reported Logan comments but not a committee commitment. Older hawkish FedWatch readings are stale, the reported SEP participant counts are inconsistent, and the shutdown/data-blackout claim conflicts with the reported October 2 payroll release, so these details do not justify overriding the live price. The truncated primary-resolution-page retrieval explicitly limits my confidence rather than establishing a different rate: settlement depends on the official December target upper bound rounded to 25 basis points, not the effective funds rate or subsequent policy changes unless the fallback applies.

The condition is not resolved or impossible: the September 16 Fed statement and FRED's October 3 observation put the current upper bound at 4.00%, leaving another 50 basis points of conventional increases necessary for Yes. There are 66 days until the scheduled December 9 decision, with a December 31, 11:59 PM ET fallback only if no December decision is issued. If nothing changes, No wins; the reported September SEP median also implies No, with one additional 25-basis-point hike taking the upper bound to 4.25%. I retain Polymarket's live 12.70% Yes anchor because the research identifies no sufficiently reliable, demonstrably unpriced information warranting a departure. A plausible No scenario is an October hold followed by a December quarter-point hike, consistent with reported patience signals from Williams on September 29 and Jefferson on October 1 and the subsequent collapse in October hike odds. Yes could result from renewed inflation pressure producing quarter-point hikes at both remaining meetings, or one half-point increase, although Logan's reported support for further tightening does not establish committee agreement or a December deadline. I discount the inconsistent SEP participant counts, conflicting shutdown/payroll narratives, and the YES report's suggestion that cumulative December hike odds can be layered onto October odds. The designated resolution-page extraction is incomplete, but corroborating official rate information reduces current-state uncertainty; settlement must follow the official December target-range decision, not the effective funds rate, and the retained Yes probability allows for policy surprises and errors in the reported guidance.

(0) The condition is not already met: the September 16 Fed statement and FRED data through October 2 put the upper bound at 4.00%, so another cumulative 50 basis points must be delivered by the December decision or, under the fallback, by December 31. (a) As of October 4, about 66 days remain until the scheduled December 8–9 meeting, with only the October 27–28 and December 8–9 meetings currently scheduled. (b) If nothing changes, the upper bound remains 4.00% and the market resolves No. (c) The clearest No scenario is an October hold followed by one 25-basis-point December hike to a 4.25% upper bound, matching Williams's call for one late-year adjustment, leadership guidance favoring patience, and the September SEP median. (d) Yes most plausibly requires back-to-back 25-basis-point hikes, although a single 50-basis-point move could also qualify; Logan supports at least 50 basis points of further tightening, and four of eighteen September SEP participants projected two additional hikes. The main Polymarket price is 12.7%, and the recent collapse in October hike odds to roughly 18% indicates that the authoritative Williams-Jefferson guidance is already substantially reflected in that anchor. I therefore stay close to the crowd but shade Yes slightly lower to 12%, because reaching 4.50% requires either a rapid reversal of that guidance or an otherwise-unsignaled jumbo December move.
