Fed decisions (Sep–Dec)

The key issue is no longer whether the Fed will keep tightening at all, but whether it will do so in the specific sequence of hike in September, pause in October, and hike again in December. The September hike is already locked in, so the market is now effectively betting on whether the Committee will step back in October while preserving the option to move again by year-end. Recent commentary from Fed officials and major banks has clearly shifted the narrative toward that kind of stop-and-go path rather than a continuous hiking cycle, which makes the exact sequence more credible than it would have been earlier in the year.

At the same time, October looks like the weakest link in the chain. The latest reporting emphasizes that policymakers may want to see how the September move filters through the economy before doing more, and several analysts have explicitly framed October as a likely pause. That helps the Yes case because the first required condition after September is a pause, but it also shows how much the outcome depends on a delicate timing judgment rather than a firm policy commitment. If the Fed decides conditions remain too hot and hikes again in October, the market resolves against Yes immediately, even if December later brings another hike.

December appears to be the stronger anchor for another move, but that does not guarantee the full pattern. Multiple market participants and bank economists have shifted toward December as the more likely next hike, yet some of the same commentary also warns that the Fed may ultimately decide no additional increase is needed this year. In other words, the path to Yes is real, but it requires both a patient October and a sufficiently strong December backdrop. The current price near even money seems to reflect that uncertainty, but I think it still overstates the chance of the exact sequence because the October pause and December hike both have to land correctly for the market to resolve Yes.

Historical and political seasonality also cuts both ways. Arguments that the Fed tends to avoid October hikes in election years may reinforce the pause thesis, but those patterns are not binding and can be overridden by inflation or growth data. With the market already leaning toward a December hike, the deciding factor is whether October data remain benign enough to justify waiting. My view is that the stop in October is more likely than not, but the probability of December producing the needed follow-up hike is still not high enough to make the full hike-pause-hike sequence the most likely outcome.
