U.S. equities typically show a brief upward bias in the months leading up to the Federal Reserve’s first interest-rate increase, with the S&P 500 posting a median gain of 2.2% in the three months prior, according to Barclays analysis of five past tightening cycles dating to 1994.
Small-capitalization stocks, as measured by the Russell 2000, were essentially flat in the same pre-hike window, highlighting a divergence in performance between large and small stocks ahead of policy shifts. Sector leadership shifted notably in the final stretch before tightening: energy and industrials outperformed, each posting median gains above 7.5%, while communication services declined by roughly 2%.
The shift in leadership becomes more pronounced once monetary tightening begins. In the quarter following the first rate hike, the Russell 2000 fell a median 7.2%, underperforming the S&P 500’s median decline of 3.9%. The financial sector recorded the steepest drop at -8.4%, while traditional defensive sectors—health care, utilities and consumer staples—also experienced valuation compression. Energy was the sole sector to eke out a gain, up 0.3%.
Style factors showed similar rotations. Value outperformed Growth, particularly among small-caps, where the lag between the two styles widened within the first two months of the tightening cycle. Momentum factors tended to outperform the broader market before the first hike but turned more sideways afterward. The small-over-big company factor weakened for about two months following the rate increase before beginning a more sustained recovery.
Barclays economists expect the Fed to remain on hold through at least the first half of 2027, with market pricing only gradually shifting toward a potential hike as early as the first FOMC meeting of 2027. Inflation data are expected to remain "sufficiently benign" to keep most FOMC members from acting prematurely, the bank said. The start of a tightening cycle is viewed as a clear inflection point for equity market leadership, with sector and style rotations accelerating once policy shifts take effect.
