Fed Decision in September?
I assess a low probability that the Fed will cut the upper bound of the federal funds rate by 50+ bps at the September 2026 FOMC meeting; my estimate is 10%, reflecting the Fed's historical preference for gradualism absent a sharp and unexpected deterioration in inflation or growth.
Analysis
As of early July 2026 the Fed's policy stance appears to be conditioned on incoming inflation and labor-market data, with the FOMC publicly emphasizing data-dependence and cautious normalization or easing only when there is clear evidence of durable disinflation or materially weaker activity. That posture makes a large, immediate 50+ bps cut at a single September meeting unlikely unless incoming data between now and September show a rapid and convincing change in the economic picture. Historically, the Fed has preferred a sequence of 25-bps moves when moving policy in the easing direction, both to manage market expectations and to preserve optionality, which biases against a single large cut absent a crisis or a policy error forcing an abrupt reversal. Market-implied probabilities (very low Yes price) already reflect the conventional view that large single-meeting moves are rare, so any meaningful upward revision to the likelihood of a 50+ bps cut would require a clear and fast-moving shock such as a sudden recession signal, a sharp collapse in inflation indicators, or systemic financial stress.
From a timing and mechanics perspective, the September meeting is early in the typical cycle of monetary-policy adjustments linked to quarterly data releases and new SEP/FOMC projections, which makes a sizable cut more plausible later in the cycle after the committee updates forecasts; that structural timing disadvantage further reduces the chance of a 50+ bps move in September. On the other hand, downside risk to growth remains a credible catalyst: significant deterioration in payrolls, real activity, or financial conditions between now and mid-September could force the Fed into faster easing than currently expected. Finally, geopolitical shocks or renewed banking-sector fragility could create pressure for a larger-than-normal cut in September, but those scenarios are low-probability exogenous events rather than the baseline path implied by the Fed's usual behavior and recent communications.
Arguments
For
- A sudden and clear recession signal in incoming data before September would create strong justification for a large, rapid cut.
- A rapid and sustained decline in inflation measures across categories would permit the FOMC to ease policy more aggressively.
- Major dislocations in the banking sector or financial markets could force the Fed to cut significantly to restore functioning and confidence.
- A coordinated global slowdown that meaningfully eases imported inflation could strengthen the case for larger cuts in a single meeting.
Against
- The Fed has a demonstrated preference for gradual 25-bps steps and is unlikely to move 50+ bps absent exceptional circumstances.
- If labor market conditions remain firm, the committee will be reluctant to approve a large reduction at the September meeting.
- Persistent or re-accelerating core inflation would make a 50+ bps cut inconsistent with the Fed’s inflation-fighting mandate.
- Advance guidance and the Fed’s desire to preserve optionality mean the committee typically waits for multiple confirming data points before delivering large moves.
Key drivers
- Incoming CPI and PCE inflation readings between July and August that show rapid and broad-based disinflation would materially increase the chance of a large cut.
- Labor market indicators (payrolls, unemployment rate, participation) moving decisively weaker would raise the probability of a 50+ bps easing action.
- Significant deterioration in financial conditions or renewed banking stress would make an abrupt, larger cut more likely as a stabilizing response.
- Fed communications and Dot Plot revisions released alongside the September SEP can shift expectations towards a larger cut if forecasts are materially downgraded.
- Global growth shocks or commodity-price collapses that sharply ease inflationary pressures could create room for a larger-than-expected move.
Risk factors
- Core inflation remaining sticky or reaccelerating would undercut any case for a large September cut.
- A tight labor market with continued wage growth would make the FOMC reluctant to deliver a 50+ bps reduction.
- The Fed’s credibility concerns about moving too quickly could lead the committee to favor smaller, incremental cuts instead of one large move.
- Markets mispricing the timing and size of Fed easing could produce volatile reactions that discourage the FOMC from acting aggressively in a single meeting.
Scenarios
Best case
Incoming data over July and August show a rapid, broad-based disinflation with clear signs of weakening growth and labor-market softness, or a sudden financial-stability shock occurs, prompting the Fed to deliver a 50+ bps cut at the September meeting to quickly ease conditions.
Most likely
The Fed either keeps rates unchanged or reduces them by a smaller increment (commonly 25 bps) after the September meeting as the committee leans on gradualism while awaiting more data, so a 50+ bps single-meeting cut does not occur.
Worst case
Inflation proves persistent or reaccelerates and labor markets remain tight, leaving the Fed to maintain rates or even tighten further, so the market resolves to No and policy tightness persists into the autumn.

What will the median home value in Miami be on September 30?
AI85%MKT8%Edge+77Hidden GemI assess an 85% probability that Miami's median home value (Parcl price-per-sqft × 2100) will be less than $1,017,000 on September 30, 2026, because a $1M+ citywide median would require an outsized, broad-based surge above typical per-square-foot medians and would be inconsistent with likely citywide housing composition and macro constraints.
