The probability reflects moderate uncertainty about economic conditions 20 months forward. September 2026 would be approximately 3+ years into the current economic cycle (assuming mid-2023 onset). Historically, easing cycles do begin by this point in mature expansions, but the timing is highly dependent on inflation trajectory and labor market health. The base rate of ~40-45% for rate cuts in FOMC meetings is adjusted downward because: (1) September is not a particularly special month for cuts, (2) the question requires at least 0.25% (a single conventional cut), which is less likely than broader easing, and (3) 20 months of additional data makes this highly contingent on macroeconomic outcomes. The 0.42 probability reflects a slightly-below-base-rate expectation, accounting for Fed conservatism and the need for clear economic deterioration or inflation cooling to justify cuts by that date. This represents genuine uncertainty about conditions in 2026 rather than a strong directional bias either way. Approximately 42% probability incorporates reasonable probability of both cutting (if growth slows or inflation continues declining) and holding (if conditions remain stable or inflationary). Base rates: Historically, the Fed cuts rates in about 30-40% of FOMC meetings during economic expansions. Since 1990, rate cuts occur more frequently during recessions or following rate-hiking cycles. The Fed has cut rates in approximately 45% of September meetings specifically, often as part of broader easing cycles that begin earlier in the year. Catalysts: By September 2026, potential catalysts for rate cuts would include: (1) sustained inflation cooling below the 2% target, (2) labor market weakening or unemployment rising above 4.5%, (3) financial market stress or credit events, (4) recession signals emerging from leading economic indicators, (5) Fed's completed rate hiking cycle potentially transitioning to cuts in 2025-2026. Counterbalancing: strong wage growth, sticky core inflation, or robust GDP growth would support maintaining higher rates. Counter-arguments: Strong counter-arguments to a 0.25% cut by September 2026: (1) The Fed typically maintains hawkish rates longer than markets expect when fighting inflation, (2) September 2026 is 20+ months away, providing ample time for economic data reassessment, (3) if inflation remains above target in mid-2026, the Fed may hold steady rather than cut, (4) a robust labor market would argue against easing, (5) the Fed's recent (2022-2023) experience shows preference for gradual policy shifts over sharp reversals, (6) Fed officials have historically signaled cutting cycles well in advance.

As of the forecast date, September 2026 is approximately 18-20 months away. The baseline probability reflects that rate cuts in specific individual FOMC meetings are relatively low (~20-25% in normal conditions). However, if economic conditions deteriorate meaningfully or if a cutting cycle is already underway by mid-2026, the probability would be higher. Given reasonable uncertainty about economic conditions 18+ months forward, and the Fed's demonstrated preference for gradual rather than emergency cuts, the probability is elevated modestly above the base rate due to the possibility of an ongoing easing cycle by that date, but remains below 50% reflecting the uncertainty and the Fed's current inflation-fighting posture. A probability of 0.28 reflects roughly 25-30% base rate plus modest adjustment for plausible mid-cycle cutting scenario. Base rates: Historically, the Federal Reserve has cut rates in approximately 25-30% of FOMC meetings during non-crisis periods. Rate cuts are more common during economic downturns or when inflation has been brought under control. Since 2000, excluding crisis years (2008-2009, 2020), the Fed has cut rates in roughly 20-25% of regular meetings. In the post-2015 period with a more stable economic baseline, cuts have occurred in fewer than 20% of meetings. Catalysts: For a cut by September 2026: (1) If inflation proves more persistent than expected and the Fed needs to stimulate growth while avoiding deflation risk; (2) A significant economic slowdown or recession beginning in 2025-2026; (3) Labor market deterioration forcing the Fed to pivot toward accommodation; (4) Geopolitical shocks or financial stability concerns requiring emergency easing; (5) If rates are already in a cutting cycle by mid-2026, momentum could support continued cuts. Counter-arguments: Strong arguments against a September 2026 cut: (1) Current Fed stance (as of early 2024) suggests rates may remain elevated through 2025 to combat inflation; (2) The 'higher for longer' narrative indicates the Fed expects sustained elevated rates; (3) Economic conditions may remain resilient, not requiring stimulus; (4) The Fed typically cuts in cycles, and if cuts don't begin until late 2025 or 2026, September 2026 would be mid-cycle, making a 25bp cut likely but not certain; (5) Energy prices and geopolitical factors may keep inflation sticky.

We are forecasting approximately 2.5 years in the future with limited visibility. The Fed's typical cutting cycle lasts 1-2 years once it begins. If cuts began in September 2023 as historically occurred, by September 2026 the cutting cycle may be largely complete or paused. Base rate of ~35% for any given FOMC meeting to cut is adjusted downward because: (1) September 2026 is likely in the latter stages of any cycle, (2) the specific meeting carries no special significance, and (3) the Fed prefers to avoid policy surprises at non-terminal meetings. However, probability is kept well above base rate because tail risks (recession, deflation, financial crisis) could drive emergency easing. The 42% probability reflects meaningful uncertainty about economic conditions 2.5 years forward while acknowledging that most FOMC meetings do not feature rate cuts. Base rates: Historically, the Fed cuts rates in roughly 30-40% of FOMC meetings during normal economic conditions. Rate cuts are more common during periods of economic slowdown, financial stress, or when inflation has persistently fallen below target. In the 2015-2019 period, the Fed cut rates at only 4 of 32 meetings (~12.5%). During the 2020 pandemic response, cuts were rapid and frequent. In 2023-2024, the Fed began cutting after a hiking cycle. By September 2026, we would be approximately 2.5 years past the initial rate cuts that began in September 2023, suggesting the cutting cycle may be in its later stages or completed. Catalysts: Economic recession or significant slowdown in 2025-2026 would increase probability of a cut. Persistent inflation below the Fed's 2% target would support easing. A financial stability event or credit market stress could trigger emergency action. Unemployment rising above the Fed's implicit target range would support accommodation. Global economic deterioration affecting US growth would be a factor. If the Fed has already cut rates substantially by mid-2026, there may be continued downward pressure if economic conditions remain weak. Counter-arguments: If inflation remains above target in 2026, the Fed would likely maintain restrictive policy. Strong labor market conditions and robust GDP growth would argue against cuts. If the Fed successfully achieves 'soft landing' after 2023-2024 hiking cycle, they may hold rates steady in 2026. Fed guidance typically provides long visibility on policy direction; if September 2026 was not previously signaled for cuts, probability diminishes. The September meeting is not typically associated with major policy shifts compared to December meetings. Institutional inertia favors maintaining the status quo once inflation is under control.

Assigning 0.42 reflects below-even odds that at least one 0.25% rate cut occurs by September 2026. This probability accounts for: (1) a non-trivial recession or severe slowdown risk over 18+ months (roughly 20-25% from baseline forecasts), which would nearly guarantee cuts; (2) a smaller probability (~10-15%) of preemptive cuts if growth falters or financial conditions tighten significantly; and (3) the baseline scenario (~60-65%) where the Fed holds steady or raises rates further due to persistent inflation or robust growth. September 2026 is relatively distant, reducing cut probability versus nearer term. The probability exceeds 0.30 due to genuine tail risk of adverse shocks; it stays below 0.50 because the consensus baseline does not price in easing by mid-2026. Base rates: Historically, the Fed cuts rates in roughly 30-35% of calendar years, but this varies significantly with economic conditions. Rate cuts are most common during recessions or slowdowns. Since 2000, the Fed has initiated cutting cycles in 2001-2003 (recession), 2007-2009 (financial crisis), 2015-2016 (preemptive), and 2019-2020 (preemptive then pandemic). The frequency of cuts in any given September is substantially lower than 50%, typically 15-25% in normal times. Catalysts: Economic recession or significant slowdown by mid-2026 would be the primary catalyst. Labor market deterioration, inflation falling below target sustainably, or a financial shock could force the Fed's hand. Current inflation trends show persistence; if inflation remains elevated through 2025-2026, rate cuts become less likely. Conversely, a sharp economic contraction would dramatically raise cut probability. Geopolitical instability or asset market stress could accelerate easing. Counter-arguments: As of early 2025, inflation remains above the Fed's 2% target and core inflation is sticky. The Fed's recent messaging emphasizes patience and data-dependence, suggesting no imminent cutting cycle. If the economy remains resilient with moderate growth and stable inflation, the Fed could hold rates steady through September 2026. The Fed also typically spaces cuts incrementally; a single 0.25% cut in September without prior cuts would suggest crisis conditions. The baseline expectation from market pricing and Fed communications is for rates to remain elevated longer than 2026.
