October ended with a burst of central bank decisions, and the outcome was a collective pause. The Federal Reserve, European Central Bank and Bank of Japan all left their policy rates unchanged during the final week of the month, matching what markets had anticipated. That removes one immediate source of pressure on equities, though it does little to settle the bigger question of where rates go next.
Inflation remains the reason. The CME FedWatch Tool still assigns roughly a 70% probability to a 25-basis-point increase at the Fed's early-December meeting. If policymakers hold steady through year-end instead, the implied odds of no hike at all by mid-March 2027 sit below 10%. In other words, the market treats a pause as a delay rather than an end to the tightening cycle.
Inflation data keeps the pressure on
The case for another move rests on a run of uncomfortable price reports. September core and headline CPI both exceeded forecasts and the prior month's readings, with headline inflation reaching its highest year-on-year level since May. Producer prices, which often foreshadow consumer costs, were even more striking: core and headline PPI hit levels last seen nearly four years ago. Then, one day after the Fed stood pat, core PCE — the gauge tied to the central bank's 2% objective — edged up to 3.1% from 3.0%. It has not printed below target since February 2021.
Notably, rate expectations were more hawkish before the Fed meeting than after it, even though two FOMC members voted for an increase. Some observers read those dissents as largely symbolic, given the majority's preference to hold and the awkwardness of tightening just days before the midterm elections.
Labor data and the AI question
Under Chair Kevin Warsh, the Fed has emphasised that policy will be data-dependent rather than guided by a preset path, and it continues to describe the return to 2% inflation as its top priority. That framing matters because the employment picture has softened. A weak non-farm payrolls report in early October was accompanied by an unwelcome rise in the unemployment rate, and payrolls have now disappointed more than once since the summer. Some analysts have begun to ask how much of US growth is genuinely broad-based once the AI infrastructure buildout is stripped out.
The AI trade itself is real, but it is unusually concentrated. If the optimistic assumptions embedded in current valuations fail to materialise, the unwind could be sharp. That risk is now colliding with third-quarter earnings season, where consensus calls for year-on-year earnings growth of roughly 30%. Results from Meta Platforms, Alphabet and Amazon have already knocked the hyperscaler trade off balance. Ahead of the Anthropic IPO, SpaceX — the only listed frontier lab — is trading at a two-month low. Semiconductors have sold off hard, and neoclouds look similarly fragile.
Midterms add a layer of uncertainty
Investors are also bracing for the November 3 midterm elections. Historical patterns suggest the outcome itself has limited bearing on broad US equity performance; earnings, growth, employment, inflation and rates typically matter more. Still, politically sensitive sectors such as energy, healthcare and technology can face shifting scrutiny when control of Congress changes, which tends to produce sector rotation rather than a uniform market move.
Prediction markets point to a Republican-controlled Senate and a Democrat-controlled House, a split that would constrain the administration's legislative agenda while leaving executive orders, trade policy and foreign policy largely intact. Divided government has often been received calmly by financial markets.
As October closes, the central challenge for equities is whether corporate results can justify elevated expectations. With the Fed still leaning hawkish and tech leadership under strain, the margin for disappointment is thin.
