EQUITY, VOL & MACRO DESK BRIEFING: US FLOWS & THEMES

Author: Giulio Esposito (Goldman Sachs Managing Director, FICC & Equities) | Date: September 14, 2026

THE TAKE: MARKET SNAPS WINNING STREAK AS RATES & OIL SHOCK TAPE

US equity benchmarks snapped a 2-week winning streak, with the S&P 500 down -80 bps and Nasdaq-100 down -66 bps. Small-caps suffered the heaviest liquidations, with the Russell 2000 falling -2.41% as interest rates surged across the yield curve (2-Year yield >4.55%, 10-Year yield >4.95%).

Equal-weight S&P 500 underperformed cap-weighted S&P 500 by ~109 bps, reflecting heavy concentration in Communication Services (+1.0%) and Tech (-0.20%). The primary sell-side catalyst was a combination of a hotter-than-expected August CPI print and a +9.4% surge in WTI crude back above $100/bbl (US diesel >$6/gal) as geopolitical risk premia and secondary sanction threats on Iran's trading partners escalated.

SPECIAL INTEGRATION: FOMC FORECAST CHANGE & HIKING CYCLE DYNAMICS

  • GS Research Forecast Update: GS Economics (David Mericle) officially added a 25 bps rate hike to the forecast for Wednesday’s September FOMC meeting, bringing the target range to 3.75%–4.00%.

  • "Forced Hike" Framing: GS notes there is little fundamental economic rationale for a hike—as CPI overshoots reflect temporary tariffs and energy shocks—but market pricing (~90%) forces the Fed's hand to prevent severe market dislocation.

  • Terminal Rate & 2027 Path: GS expects the Fed to frame this as a "one-and-done" adjustment for 2026, followed by two 25 bps cuts in 2027 (September and December), bringing the terminal rate forecast to 3.25%–3.50%.

  • Equity Impact vs. Historical Precedent: While the S&P 500 has historically averaged -2% over 3 months following the first hike of a cycle, it averages +9% over the subsequent 12 months. Because rates markets already price >3 hikes by mid-2027, the bar for a hawkish surprise is exceptionally high.
