〔Day Digest〕Goldman Slides the Hike to December on Cooler Inflation as 93bp Stays Priced and 10Y Maps 5.5-6% - Long-End Refuses the Pivot, Samsung's 100T KRW HBM Year Caps 2027

0. Daily Arc

A cooler-inflation read drags Goldman's next-Fed-hike call into December ^[1][2], but money markets still price 93bp of tightening over the next 12 months ^[3] — a near-fully-priced cycle while the long end keeps drifting higher. T.Rowe Price maps the 10Y to 5.5%-6% on resilient US growth ^[4], Jefferies calls current levels attractive for long-term buyers but flags directional uncertainty ^[3], and Howard Marks frames the structural problem as a bill to be paid, not a crisis to be averted ^[5]. The pivot narrative coexists with long-end resistance — and Goldman's 100 trillion KRW 2027 HBM revenue call on Samsung pins down where the supply gap actually bites ^[6].

1. Fed Path and Rates

• **[NEW] Goldman's December call:** Goldman Sachs pushed its next Fed rate hike forecast to December following cooler inflation ^[1][2]. Sourcing is thin — both items are headline relays without underlying detail ^[1][2].
• **[NEW] Market pricing vs conviction:** LSEG data show money markets are pricing 93bp of cumulative Fed hikes over the next 12 months ^[3]. Jefferies' Mohit Kumar is more confident central banks won't deliver as much as priced, but less confident about the direction of the next 10bp move in the 10Y ^[3].
• **[ONGOING] Pivot vs pricing gap:** Goldman and the OIS curve now point to December as the next hike, yet the cumulative 93bp priced implies a still-hawkish path that contradicts the "less than priced" lean from Jefferies ^[3][1][2].

2. Long-End Resistance

• **[NEW] T.Rowe Price 5.5%-6% scenario:** David Clewell, co-portfolio manager of Multi-Asset Global Income Strategy at T.Rowe Price, says the 10Y at 5% has been a key psychological level, and resilient US growth supports a 5.5%-6% scenario ^[4].
• **[ESCALATED] Howard Marks' September memo:** Oaktree co-founder Howard Marks notes August 17 saw the 30Y close above 5.3% — a 19-year high at that time — and the August 19 Treasury move to raise the long-bond repurchase single-cap from $2B to $4B drew a one-day dip that reversed the next session ^[5]. He cites Drukenmiller: "if 30Y must clear at 5.5%, that's not a crisis, it's a bill" ^[5]. Resolution: pay the bill or change behavior ^[5].
• **[NEW] Jefferies' contrarian buy:** Kumar calls current UST yield levels attractive for long-term investors despite high uncertainty, with confidence tilted to "less hiking than priced" rather than the direction of the next 10bp ^[3].

3. Equity: Samsung and the HBM Bottleneck

• **[NEW] Goldman reiterates Buy on Samsung:** 3Q26 operating profit and 2027 HBM revenue both expected to exceed 100 trillion KRW ^[6]. Current share price implies 2027E P/E of 3.6x, P/B of 1.6x, and ROE of 53% ^[6].
• **[NEW] Supply gap framing:** Storage demand significantly exceeds supply, with the gap expected to widen in 2027 and continue into 2028 ^[6]. 2027-2028 earnings estimates run 8%-17% above BBG consensus, driven by higher DRAM ASP assumptions — especially HBM — that outweigh downward revisions to traditional DRAM shipment ^[6].
• **[NEW] Mechanism:** HBM focus will relatively limit traditional DRAM bit output, further tightening 2027 supply and reinforcing the share-of-wallet tilt toward HBM ^[6].

4. What Would Falsify

• Goldman's December call rests on the cooler-inflation read; the August/September CPI and payrolls pair is the cleanest test, but the supporting sourcing is two thin headline relays rather than the underlying note ^[1][2].
• The 5.5%-6% long-end path needs a growth print, not just a supply technical — Clewell's scenario is conditional on resilience ^[4], and the August 19 repurchase bump-and-reverse shows the marginal buyer's limits near 5.3% on the 30Y ^[5]. Jefferies' "attractive at current levels" is the cleanest contrarian anchor ^[3].
• The Samsung 100 trillion KRW HBM call is the supply-side anchor for the 2027 narrative; a single-quarter DRAM shipment downgrade, HBM ASP slip, or rival capacity surprise would test the 8-17% consensus gap that Goldman is running above ^[6].
