Pronóstico: Fed Decision in September?

Platform comparison

Market context

The Federal Reserve is widely expected to hold rates steady at its September 2026 meeting, with the upper bound of the target federal funds range unchanged from its prior level. This real-world consensus is reflected on Polymarket today, where the "Fed Decision in September?" contract shows a 2% crowd-implied probability for a rate hike (YES), priced at 0.02 USDC on the Polygon network. Traders using conditional tokens can buy or sell shares in this outcome, with payouts redeemable in USDC upon resolution, mirroring the market’s low confidence in any upward move.

Historically, similar low-probability scenarios for rate hikes have often preceded periods of policy stability, especially when the Fed’s dot plot signals caution. In Kevin Warsh’s first meeting as chair, the Fed held rates steady despite a hawkish tone, with futures markets later pricing in a hike only for October, not September [3]. This pattern suggests that September 2026 may follow the same trajectory, where elevated expectations for a year-end hike do not translate into immediate action, reinforcing the 2% market price.

Traders should monitor the July 29 FOMC meeting’s economic projections and the September 10 employment data, both critical for shaping September’s policy stance. Goldman Sachs has recently pushed its rate cut forecast to 2027, noting that hikes are unlikely though slightly more probable than before [4]. Additionally, the CME FedWatch Tool, which tracks 30-Day Fed Funds futures, will offer real-time signals on shifting hike probabilities [5]. Any surprise in inflation data or Middle East developments could alter the baseline, but current indicators support the market’s lean toward no change.
