Global Daily Briefing

Brent crude's 7% decline on US-Iran deal optimism cascaded across 13 markets through two channels: (1) CPI relief for net importers — India's FII flip to Rs 3,857 crore buying (Anjali Mehta's India brief), Japan new intraday highs on Hormuz reopening thesis (Daniel Park), UAE DFM +1.1% on regional de-escalation pricing (Marcus Adebayo); (2) Revenue compression for exporters — UK Shell -1.40% and BP -1.14% (Eva Muller), Brazil IBOV -1.73% with Petrobras earnings sensitivity ~R$20B per $10/barrel Brent move (Marcus Adebayo), Canada energy softening despite BlackBerry's outlier surge (Sarah Williams). ASML +2.57%, TSLA +1.95%, NVO +1.28%, AAPL +1.26% led global gainers; LVMUY -2.34%, NVDA -1.9%, SONY -1.86%, SHEL -1.40% led losers — confirming the oil-driven bifurcation ran through luxury, energy, and auto sectors globally. The binary for Tuesday: formal Iran announcement extends the divide; a breakdown reverses it within 48 hours.

Independent of oil, China's CSRC launched a crackdown on cross-border trading platforms that sent FUTU Holdings crashing 27.5% and put HK$250 billion in cross-border assets under scrutiny. HSI proxy fell 1.4% (James Chen's HK brief), with Southbound mainland flow direction on Tuesday as the immediate tell. China's CSI 300 proxy dropped 1.0% with all sectors in the red (James Chen's China brief). Korea's KOSPI fell 2.3% as foreign selling extended its 12-session streak — 40 trillion KRW of cumulative net foreign selling shows institutional EM reduction is broader than China/HK alone (Daniel Park's Korea brief). Singapore STI managed +0.1% on company-specific earnings (Boustead +145%, SATS Q4 +31%), providing the clearest counter-example: idiosyncratic corporate catalysts can offset macro headwinds. The systemic risk: if CSRC extends the crackdown to Tiger Brokers and Webull, the regulatory friction on international access to Chinese equities rises structurally — a multi-quarter Hong Kong financial centre risk that can't be hedged through oil instruments.

The day's most durable global equity signal: semiconductor equipment and AI infrastructure capex rallied simultaneously across three regions. ASML surged 2.57% to $1,632.90 (globally the top large-cap performer). Germany's Infineon (IFNNY) +5.35% as Eva Muller's Germany brief documented the auto-to-AI pivot re-rating thesis. US AMD +4.0% on a $10B+ Taiwan AI infrastructure pledge; Applied Materials exceeded quarterly revenue forecasts. This cross-Atlantic alignment — ASML (European litho node), Infineon (German power semis), AMD (US GPU challenger), TSMC (Taiwan manufacturing) — is a regime signal: the AI capex cycle is now a global factor exposure, not a US-only allocation. The one dissonant note within the complex: NVDA -1.9% to $215.33 on Huawei's chip breakthrough claim incrementally narrowing the long-term moat narrative. For Tuesday's Asia open, Samsung and SK Hynix are the HBM memory bellwethers — if they open higher despite Korea's KOSPI selloff, the cross-region AI trade is intact.
