What changed since premarket

Record diesel and Brent near $100 sharpen inflation risk; AI optics/photonics re-rate on Goldman upgrades, Korean memory trades at 4.8x with 50%+ HBM hikes expected, and the Fed path hinges on CPI as convexity lifts long-end yields.

Main narratives

day change
01

Tanker strikes and record diesel cracks are a supply-side inflation shock

US strikes on Iranian tankers near Kharg Island and Houthi attacks on Saudi sites pushed Brent toward $100. Hormuz crude flows are roughly half pre-war levels; US distillate stocks are at 25-year lows and diesel cracks hit a record $106. Goldman sees $120 Brent if disruption persists into 2027, while some traders argue attacking Iran's export base is bearish once retaliation fades.

02

Optical module TAM upgrades extend the AI infrastructure trade beyond GPUs

Goldman raised optical module market forecasts to $67.7B for 2026, $131.4B for 2027, and $148.5B for 2028, with 1.6T penetration accelerating on Nvidia's Rubin Ultra platform. Verizon's multi-billion-dollar fiber deal with Corning extends through 2032. Independent photonics voices saw broad re-rating across LITE, COHR, AAOI, GLW, and CIEN.

03

Korean memory trades at 4.8x forward while HBM price consensus expects 50%+ gains

Kim Jang-yeol argues consensus sees HBM prices jumping over 50% by year-end, key to next year's earnings. Samsung and SK Hynix trade near 4.8x forward P/E after won-strength adjustments, still at a 30% discount to Micron, and HBM's 3x DRAM wafer consumption tightens supply. Daishin notes 2028 HBM demand projections exceed 40 billion Gb.

04

Hike-or-pause debate collides with convexity-driven pressure on 30-year yields

El-Erian argues against hiking, while Seema Shah warns a September hold risks credibility; markets put 60% odds on a hike with CPI as tiebreaker. BMO's Davis says mortgage convexity hedgers are the last major duration seller, making 10-year yields at 5.00-5.25% a larger buy. Gundlach says funds are 50bps too low and tells investors to avoid 30-year bonds.

Themes of the session
