〔Overnight Brief〕Bond Vigilantes Force the Fed's Hand: September Hike Odds Hit 87-90% as 10Y Tops 5% and 30Y Hits a 2007 High, Yet BofA's Top Bear Lifts S&P 500 to 7,400 — Wednesday Dot Plot Decides

0. Overnight Arc

The hot US August CPI flipped the Fed narrative from "one and done" to "forced to hike": implied September odds reached 87.3% by Sept 13 on CME FedWatch ^[1] and ~90% at the print's peak ^[2], pulling in Morgan Stanley ^[3], MUFG ^[4] and Pantheon ^[5] as confirmed September callers. The long end responded violently — 10Y above 5% for the first time since 2023 ^[6], 30Y at a 2007 high ^[2] — yet BofA's Subramanian, called a top equity bear, lifted her S&P 500 year-end target to 7,400 ^[7][8] while MRA's Curnutt warned of an 8-10% pullback ^[6]. Net: a bond market that has declared victory against the equity rally, with the Wednesday dot plot as the tiebreaker.

1. Fed Repricing — From "One and Done" to "Forced to Hike"

• **[ESCALATED] Morgan Stanley:** predicts Fed hikes in both September and December ^[3], with global head of macro strategy Matt Hornbach expecting a 25bp move on Wednesday and conceding "it is certainly a possibility that the Fed is one and done but that is not what the markets are pricing in at the moment" ^[9].
• **[ESCALATED] MUFG:** changed stance to expecting a September FOMC hike after a strong NFP and a hot CPI print ^[4].
• **[ESCALATED] Pantheon Macro:** sees a hike this week as disinflation stalls ^[5].
• **[NEW] Market pricing:** CME FedWatch showed 87.3% probability of a September hike as of Sept 13 ^[1]; the asset-allocation desk noted the implied rate briefly hit ~90% after the CPI print before fading ^[2]. Quote as a band, not a point.
• **[NEW] Contrarian — Macro Hive:** previews "one 2026 hike, longer normalization," implying the market has over-priced the path ^[10]. Hornbach's own "one and done is a possibility" caveat ^[9] keeps the alternative live. Contradiction is content, not a defect.
• **[NEW] Cross-Atlantic — ECB:** raised three key rates by 25bp on Sept 10 ^[1][2], with Christine Lagarde flagging inflation risks tilted to the upside ^[2] — adding a global-tightening leg to the Fed story.

2. Bond Vigilantes — Bear Steepener Resumes

• **[ESCALATED] Yield blowout:** the US 10Y broke 5% for the first time since 2023 per MRA's Curnutt ^[6]; the 30Y hit a fresh high not seen since 2007 per the asset-allocation desk ^[2].
• **[NEW] Sell-side revisions:** Citi, Goldman Sachs and JPMorgan all raised their year-end US Treasury yield forecasts after the CPI print ^[11].
• **[NEW] Veteran voice:** the strategist who earlier called for benchmark yields at 5% this year says the selloff is not done ^[12] — flagging further upside in yields.
• **[ONGOING] Supply/technical strain:** Treasury buyback expansion met a cold shoulder ^[2]; US-Japan FX coordination to defend the yen had limited effect on US yields, and the root cause — the US-Japan rate differential and carry trades — remains unresolved ^[2].
• Source quality control: the 5% breach and 2007-high 30Y claims are relayed through single-source research notes ^[2][6], not direct market quotes — treat as a band, not a tick.

3. Equities — BofA's Bear Lifts Target vs. MRA's 10% Pullback Call

• **[NEW] BofA's Savita Subramanian:** raised the S&P 500 year-end target to 7,400 (from 7,100), with a 12-month target of 7,800 ^[7], while still flagging the index is "prone to interest-rate risks" ^[8]. The framing matters: a known bear is capitulating upward, but not dropping the rate caveat.
• **[NEW] MacroRiskAdvisors' Dean Curnutt:** expects the Fed to launch a hike cycle that pressures the S&P 500 into an 8-10% pullback, drawing the parallel to 2018 (September peak, October-November 10% drop, December further weakness) and flagging a possible second-leg decline by year-end if hikes continue ^[6].
• **[NEW] Citi:** a Fed rate hike could deliver a stock-market shock, per thestreet.com relay ^[13].
• Net: two sell-side houses are roughly 1,000 S&P points apart on the 12-month view (MRA implies ~6,800 on the bear case, BofA 7,800). Wednesday's dot plot is the test.

4. China A-Shares and Hong Kong — Rate Pain Hits HK, AI Optics Carry A-Shares

• **[NEW] A-shares weekly:** Shanghai Composite -1.07% to 3,888.11; Shenzhen Component -0.34% to 13,471.26; ChiNext +1.08% to 3,322.04 — the only broad-index gainer ^[14]. Average daily turnover 1.893 trillion yuan, down 3.90% week-on-week ^[14]. Total margin balance 2.6316 trillion yuan, down 0.24% ^[14].
• **[NEW] Sector split:** Telecom +6.87% led, building materials +3.05%, national defense +2.01%, electronics +1.30% ^[14]. Laggards: non-bank finance -4.62%, computer -4.61%, food & beverage -3.78% ^[15].
• **[NEW] Hong Kong hammered:** Hang Seng -3.30% on the week, Hang Seng Tech -5.45% — the rate repricing hit high-beta tech hardest ^[1]. Southbound capital net inflows rose sharply, with turnover in energy and telecom climbing 28.65% and 4.58% week-on-week ^[1].
• **[NEW] PBOC posture:** Deputy Governor Lu Lei said the central bank will refine the reserve requirement framework, run flexible and precise OMO, and keep short-end money-market rates anchored around the policy rate ^[1].
• **[NEW] ECB hiked 25bp on Sept 10** ^[1][2] — global tightening, not just Fed.

5. AI Supply Story — Goldman's Optical-Module Call and Adjacent Lines

• **[NEW] Goldman (1.44 / 1.71):** raised 2027/2028 800G-and-above optical-module demand forecasts by 39% and 36% to 144 million and 171 million units after surveying 15 Chinese optical communications firms ^[16]. 1.6T module price is now expected to hold above $700; 800G price decline in 2027 is seen at single digits only ^[16].
• **[NEW] Bottleneck shift:** Goldman says the constraint has moved from demand to supply — DSP and laser chips are scarce, and leading module makers are using prepayments and long-term agreements to lock capacity ^[16].
• **[NEW] CPO ramp:** Goldman forecasts CPO switch shipments will jump from 10,000 units in 2026 to 131,000 in 2028, with test-and-coupling equipment vendors as the earliest revenue beneficiaries; Roboter (罗博特科) Q2 revenue was up 172% q/q, 141% above Goldman's prior expectation ^[16].
• **[NEW] Adjacent AI research lines:** embedded PCB (埋嵌PCB) — value per unit is significantly higher than traditional PCB, with manufacturers positioned in the process expected to benefit ^[17]; ceramic substrate (陶瓷基板) for AI servers, paired with TEC cooling films, is a core incremental segment ^[18]; AI developing taking over from AI coding as a thematic line ^[19].
• **[NEW] Stock-level call:** Morgan Stanley rated EchoStar (回声星通信) overweight with a $134 target ^[20] — single-name note, source thin.
