The Daily: CPI + Iran War - Why Markets Are Nervous Again

MACRO – What’s Driving Overnight Risk?

Overnight Price Action

• Asia: Lower; Japan fell 1.7% and South Korea dropped 4.5% as AI weakness and Iran risk pressured sentiment
• Europe: Lower; Euro Stoxx 50 and FTSE 100 both down around 0.4% in early trade
• U.S.: Futures lower; Nasdaq underperforming as Nvidia, Broadcom, Micron, and AI hardware names remain under pressure
• Rates: Treasury yields broadly flat-to-firmer; CPI risk keeps Fed hike odds active
• FX: Dollar flat-to-firmer; geopolitical risk and elevated U.S. yields continue supporting the greenback
• Commodities: Oil broadly flat near the low-$90s despite fresh U.S.-Iran strikes, while gold extended losses and turned slightly negative for the year

Catalysts

• U.S. and Iran exchanged strikes overnight after Trump retaliated for the downing of an American Apache helicopter; U.S. forces hit Iranian air defenses, ground-control stations, and radar sites near Hormuz; Iran launched missiles at four U.S. targets and drones toward the main U.S. naval base
• U.S. CPI due this morning; headline expected to jump to 4.2% y/y from 3.8%, with core expected at 2.9%
• China CPI held at 1.2% y/y, while PPI accelerated to 3.9%, the fastest since July 2022
• APAC and European equities sold off as investors reduced risk ahead of CPI and after renewed Gulf escalation
• TSMC reported May sales up 30% y/y, reinforcing continued AI infrastructure demand
• SoftBank’s talks for a $6B margin loan to invest in OpenAI, backed by its OpenAI equity stake, reportedly stalled
• Gold extended its decline despite renewed strikes, showing real-yield and dollar pressure still dominate safe-haven demand

Market Implication

Markets are back to trading the three-front war: oil and geopolitics, semiconductors and AI, and the Fed’s inflation timeline. CPI is today’s main macro catalyst. A soft print gives the Nasdaq room to stabilize. A hot print with Gulf escalation still active would keep pressure on growth and reinforce the market’s shift toward quality, cash flow, and defined risk.

THEMATIC – Forces Behind the Tape

1. Iran Headlines are Back in the Inflation Channel

The U.S.-Iran conflict has moved back into the market’s inflation channel. The latest exchange followed Iran’s downing of an American Apache helicopter, with the U.S. striking Iranian air defenses, ground-control stations, and radar sites near Hormuz. Oil’s reaction has been contained so far, which is important. Brent near the low-$90s is manageable for equities, but the lack of a large oil spike should not be confused with a clean de-escalation. Hormuz remains the key transit point, and the market is still assuming energy flows will avoid a true breakdown. That assumption is doing a lot of work.

In terms of strategic approach for traders, the crude line remains straightforward. Brent below $95 helps risk appetite. Brent back above $100 brings inflation expectations, gasoline pressure, and Treasury yields back into the center of the tape. Energy exposure still works as a hedge, but crude remains too headline-sensitive for oversized directional bets. Spikes in oil volatility are better handled with defined-risk structures and selective premium selling after IV expands.

2. The AI Trade Still Has Demand, But Funding Stress is Emerging

The semiconductor trade remains under pressure, but the demand side has not disappeared. TSMC reported May sales up 30%, with April and May combined revenue up around 24% from a year ago. Analysts are still looking for second-quarter sales growth around 35%, which tells you AI infrastructure demand remains strong at the foundry level.

The problem is positioning and financing. Nvidia, Broadcom, Micron, and the broader hardware complex are still working through last week’s reset. Meanwhile, SoftBank’s stalled talks for a $6B margin loan backed by its OpenAI stake are a reminder that the AI buildout is becoming a funding story as much as an earnings story. When AI equity exposure is used as collateral to borrow money to get more AI equity exposure, circular financing concerns aside, the trade becomes much more sensitive to valuation, liquidity, and financing conditions.

3. CPI Determines Whether the Fed Timeline Tightens Again

May U.S. CPI is the day’s main event. Markets saw headline inflation to jump to 4.2% y/y from 3.8%, while core inflation edged up to 2.9%. The risk of a hot surprise mattered because Cleveland Fed nowcast models undershot last month’s actual print by the widest margin since 2022. But core inflation came in below expectations, and is running at an annualized pace on par with the Fed’s 2% inflation target. For equities, the 10Y remains the tactical line. Below 4.50%, growth gets breathing room. Toward 4.70%, valuation pressure returns quickly. A soft CPI would support semis and AI infrastructure. A hot CPI would keep the market in a quality-first, cash-flow-first, defined-risk regime.

MICRO – Today’s U.S. Catalysts

Economic Calendar (CT)

• 7:30 – May U.S. CPI; markets focused on headline inflation, core services, gasoline pass-through, and Fed hike pricing

Earnings Focus

• Oracle reports after the close; focus is on OCI growth, AI backlog, RPO, margins, and capex intensity
• Watch Nvidia, Broadcom, Micron, Marvell, Dell, HPE, Super Micro, and TSMC-linked suppliers for AI infrastructure read-throughs

Fed Watch

• CPI is the final major inflation read before Warsh’s first FOMC meeting next week
• Markets continue pricing no near-term cuts and some risk of another hike in 2026
• Watch whether the 10Y holds below 4.70% after CPI

TRENDING – Retail Radar

• U.S.-Iran strikes, Apache helicopter retaliation
• Semiconductor weakness, TSMC sales growth
• SoftBank funding stall
• Oracle earnings
• Gold negative YTD

KEY LEVELS TO WATCH

• S&P 500 (/ESM6) – Support/Resistance: 7354/7632
• Nasdaq 100 (/NQM6) – Support/Resistance: 28663/30693
• Crude Oil (/CLN6) – Support/Resistance: 77.22/105.21
• U.S. 10Y Yield – holding north of 4.50%
• VIX – set to open above 19 again after rising above 23 yesterday

Trade Setup Bias

Neutral with tight risk management into CPI. Lower oil helps, but renewed Gulf escalation and semiconductor weakness keep the tape fragile. Favor defined-risk structures, quality AI infrastructure names after stabilization, and selective premium selling only after IV expands. Avoid chasing semis until breadth improves and yields confirm.

Bottom Line

Today is CPI plus Iran plus semiconductors. That is the market’s three-front war in real time. Oil remains below the panic zone, but the conflict is unresolved. AI infrastructure remains the strongest secular theme, but the trade is crowded and funding-sensitive. CPI decides whether yields give the Nasdaq relief or tighten the tape again.
