GS CROSS-ASSET FRANCHISE BRIEFING: SEPTEMBER FOMC PREVIEW

THE TAKE: MARKET PRICING FORCES FED HAND INTO 25BP "POLICY HIKE"

Goldman Sachs US Economics officially added a 25 bps rate hike to its forecast for the September 16 FOMC meeting. The driver is not a shift in fundamental inflation dynamics, but rather ~90% market pricing, which leaves the Fed with little choice: staying on hold would trigger severe market dislocation and steepen the long end of the yield curve.

Governor Waller is expected to explicitly dissent, as recent inflation prints have landed below his personal threshold for tightening. The primary market catalyst will be whether the dot plot median shows one vs. two hikes in 2026 (GS expects a 10-8 majority for one hike).

DESK-BY-DESK CROSS-ASSET ACTION PLAN

  • Rates & Volatility:

    • Vol Stress & Convexity: 30-year tails have significantly underperformed the move higher in rate vols. Owning 30y payer convexity offers cheap tail protection relative to the rest of the surface.

    • Curve Dynamics: A "dovish hike" reintroduces curve steepening risks; a hawkish dot plot keeps the curve biased flatter. GS Rates Strategy notes today's backdrop aligns more with limited post-hike flattening risk (similar to 1997/1999).

  • Foreign Exchange (FX):

    • Dovish Hike Trade: Sell USD against JPY and AUD on a dovish hike framing. A hawkish BoJ on Thursday combined with a dovish Fed could send USD/JPY back toward 152.00 and push AUD/USD onto a 0.7200 handle.

    • EUR Setup: EUR/USD short positioning remains a favored expression into the meeting, but a broader USD sell-off could lift EUR back above its 200-day moving average (~1.1630).

  • Commodities (Gold & Crude):

    • Gold (GLD Calls): Front-end upside convexity remains cheap. Desk recommends holding wingy GLD calls into the event to capture asymmetry in the event of an unexpected hold.

    • Oil (Put Skew): Shutdown of Saudi Arabia's East-West pipeline repriced the right-tail risk upward, but regional de-escalation presents deep downside potential. Desk favors buying oil downside puts on potential Hormuz/Saudi diplomatic resolution.

  • Equities & Credit:

    • Implied Event Move: SPX implied event gap sits at ~47 bps. Desk views Wednesday's implied move as an "own" given historical realized volatility spikes on FOMC/VIX expiry overlap days.

    • Credit Hedges: Decompression flows continue to pressure HY corporates. Desk favors buying super senior tranches in HY45 (locking in ~4yr convexity near all-time tights) and outright payers in CDX.
