The Edge
Today's most important themes: Fed hike consensus meets oil and AI risk
TL;DR
🔴 Fed hike near-lock-in — Citi, Goldman, JPMorgan, UBS and Morgan Stanley now all expect a 25bp hike to 3.75%-4.00% this week, with markets pricing ~90% odds; Citi and Vital Knowledge both frame it as one-and-done, not a new tightening cycle.
🔴 Semis sell, software rallies — today's tape confirms the rotation: SMH -4.75%, INTC -5.59%, MU -5.25%, AVGO -4.77% while IGV gains 5.04% and CIBR jumps 5.99%. Goldman's Chart of the Day says the 3-month vs 12-month momentum gap just hit its widest in five years as AI exposure decouples from the momentum factor.
🟡 Oil-driven stagflation risk — WTI is up 1.84% to $101.89 today; Gavekal and Citadel Securities warn suspected Saudi/Russian refinery and pipeline attacks are reviving stagflation odds, while Vital Knowledge and World Gold Council cite their own intraday Brent prints above $100-$108.
🔴 Long yields near 5% — the actual 10-year sits at 4.96% (-1.4bps) and the 30-year at 5.33% today. Goldman lifts its year-end 2026 10-year forecast to 4.75%, and JPMorgan argues the S&P 500 can absorb yields near 6% given 28%/21% projected 2026/27 EPS growth.
⚪ AI capex debate widens — Citi says AI labs' calls to self-pace frontier development are both a sincere safety move and an attempt to shape regulation before it's forced on them, while Goldman's Communacopia takeaways argue capex stays elevated through 2027 as internet leaders pivot from experiments to measurable ROI.
