〔Overnight Brief〕Warsh's Jackson Hole Debut Lifts September Hike Odds to 65.1% and 2Y to 4.34% — Earnings 'Armor' and 'Ping-Pong' Equities Test the New Hawk

0. Weekly Arc

The hawkish pivot led by new Fed Chair Kevin Warsh at Jackson Hole re-priced the September distribution decisively: 25bp odds climbed from 35.8% to 65.1% and the 2-year Treasury yield touched 4.34% ^[1]. ING flags that the September hike bias is 'shifting' and Jim Bianco argues the meeting may include a historic ex-Powell voting wrinkle ^[2][3]. Equities have not capitulated — Nasdaq 100 ended August +4.18% at a PE TTM of 30.31x (64.93% historical percentile) ^[4] — and Goldman Sachs Asset Management's Katherine Bordlemay argues earnings breadth is the 'armor' tolerating higher yields, expecting a 'ping-pong' of volatility even as indexes grind higher ^[5][6][7]. Net: a hawkish front-end repricing meets an earnings-bid tape ^[5][1][4][7].

5. What Decides Next

• The September FOMC is the test: with 65.1% priced and the ex-Powell vote wrinkle in play, a hold or dovish surprise would force a 2Y reversal toward the pre-Warsh range; a 25bp hike on top of a 4.34% 2Y tests the equity 'armor' thesis articulated by Bordlemay ^{[2][5][1][6][7]}.
• Falsifiable reads: (i) the non-ferrous index at 5553.49 with TR(1) 72.75 and a flattening short-term MA slope — a break below the 5418.22 medium-term MA would confirm trend exhaustion ^[11]; (ii) the September calendar-effect readout against a still-elevated 64.93% historical Nasdaq 100 PE percentile ^[4]; (iii) A-share crowding release is constructive but revenue growth has to keep double-digits to sustain the +20%+ non-financial net profit pace ^[13][12][15].
• Source-quality note: the ^[1] monthly macro deck is the cleanest single-source read on the Warsh pivot; ^[2] is a single Bianco column with the ex-Powell framing; ^[3] is a headline-level ING tag; ^[14] and ^[18] are Chinese research-headline aggregators with no underlying numbers — treat as direction-only.
