〔Overnight Brief〕Supply Story Pushes 10Y Toward 4.8% as Intraday High Hits 4.7458%; Cabana Calls It a Fed Story - FOMC Minutes Today

0. Weekly Arc

The long-end grind extended through Tuesday's U.S. session, with the 10Y threatening 4.8% and the 30Y already through its longer-term technical pressure band ^[1]. NY saw a modest pullback — 10Y -1.59bp to 4.7060%, 30Y -2.03bp to 5.2858% — but only after an intraday high of 4.7458% on the 10Y, within striking distance of the January 14, 2025 peak at 4.8069% ^[2]. Mortgage News Daily frames the bigger move: yields have been 'calmly but clearly' skewed higher for almost 10 months, with ceilings at 4.3%, 4.42%, and 4.75% giving way in sequence ^[3]. Net: long-end supply meets a Fed that has stopped talking ^[4].

1. The Long-End Mechanism

• **[ESCALATED] Supply thesis — Rich Privorotsky, Goldman Delta-one head:** the long-end rise is a supply problem, not central bank discipline; sovereign deficits plus AI capex of more than $1T annually are flooding the bond market ^[1]. The 10Y is at a 'key node'; a close above 4.8% could trigger a real short-squeeze ^[1]. Flag: relayed through a Chinese-language outlet translating the original commentary — single source ^[1].
• **[ONGOING] Auction stress — Reuters:** persistently higher stop-out yields at Treasury auctions are lifting refinancing costs and questioning investor appetite for U.S. debt ^[5]. Tuesday's 6-week T-bill stop-out came in at 3.645%, down from 3.67% ^[6].
• **[ONGOING] Mortgages decouple — Mortgage News Daily:** the top-tier 30Y fixed rose 0.02% to 6.75% for a third straight day even as the bond market firmed slightly ^[7]. Lender timing — once-a-day rate sheets around 10am ET — explains the gap ^[7].
• **[ONGOING] Kitco framing:** 10Y yields are back at levels last seen in October 2023 even though the policy rate has been cut from 5.5% to 3.75% ^[8].

2. Fed Communication Vacuum

• **[NEW] Chair Warsh's compression — David Wilcox, Bloomberg Economics:** Warsh has cut FOMC statement length by more than half vs. the Powell era and has fully removed any hint of the future direction of rates ^[4]. Wilcox argues this won't improve private forecaster accuracy and leaves markets without guidance ^[4].
• **[NEW] Jackson Hole expectations — BofA August fund manager survey:** 31% expect hawkish Warsh at Jackson Hole, 7% dovish, majority neutral ^[9]. The tape is already pricing dovish: the dollar traded range-bound as markets priced a softer Fed response ^[10], and option traders are hedging 2027 cut risk ^[11][12].
• **[NEW] Sell-side split:**
• BofA's Mark Cabana: the bond selloff is mostly a Fed story ^[13].
• JPM's Kay Herr: the Fed should 'just hike and move on with it'; the market 'really doesn't love the fact that we don't have forward guidance' ^[14].
• Constitution Capital's Jeff Schoor: concerns about hikes are diminishing, with some positions being unwound ^[12].

3. Data and Funding Tells

• **[NEW] July Industrial Production:** total +0.2% m/m, manufacturing +0.2%, motor vehicles & parts -2.1%, utilities +0.5%, mining +0.2%; capacity utilization 76.3% vs. 76.30% consensus, prior revised to 76.2% from 76.1% ^[15][16][17].
• **[NEW] Housing softens:** July pending existing home sales -2.3% m/m vs. 0.0% expected ^[18].
• **[NEW] Inflation expectations — Cleveland Fed survey:** business executives see one-year CPI at 3.3% (down from 3.7% in Q2), wage growth at 2.8% (vs. 2.9% prior), and R&D spend growth slowing to 2.0% from 3.1% ^[19].
• **[ONGOING] RRP drainage:** Fed overnight reverse repo usage fell to $155M (6 counterparties) on Tuesday from $2.55B the prior session ^[20]. One-day print, low signal.
• **[NEW] Macro pessimist — David Rosenberg:** the U.S. economy is 'losing momentum' ^[21]. Combine with 2027 cut hedging ^[11][12] and you get a tactical dovish trade stacked against a structural long-end selloff.

4. Contrarian and Tail Risks

• The 'supply, not the Fed' thesis ^[1] and the 'Fed story' thesis ^[13] are live simultaneously; the falsifiable test is the July FOMC minutes due today ^[22] and Chair Warsh's Jackson Hole speech later this month ^[9]. If Warsh keeps the FOMC opaque, the long end has more room to drift ^[4][23].
• **Source quality flags:** the supply/capex framing is a single-source relay of Goldman commentary ^[1]; the BofA fund manager survey is a single poll ^[9]; the RRP print is a one-day observation across only six counterparties ^[20]; the AI capex $1T figure is unsourced inside the relay ^[1]. Quote each as such.
• **What would falsify the supply story:** a 4.8% 10Y close that fails to hold, plus a hawkish-leaning FOMC minutes print ^[1][22]. **What would falsify the Fed story:** a Jackson Hole that delivers neutrality plus continued absorption at the long-end auctions ^[9][5].
