Weekly Macro Study — Week of October 11, 2026

1. The Fed Hikes for the First Time Since 2023

On September 16, 2026, the FOMC voted 12-0 to raise the federal funds target range by 25bp to 3.75%-4.00%. This is the first rate hike since 2023, marking a dramatic policy pivot under new Fed Chair Kevin Warsh.

Key statement language: "The Committee will deliver price stability." — a deliberate shift from the previous "patient" framing.

SEP projections (median):

• Real GDP: 2.3% (2026), 2.4% (2027)
• PCE inflation: 3.7% (2026), 2.3% (2027)
• Unemployment: ~4.1% (steady)
• Fed funds rate: 4.1% by end of 2026, unchanged through 2027

Warsh's press conference tone: "I would be hard pressed to describe broad financial conditions as restrictive." The hike is framed as removing accommodation, not tightening into restriction. Inflation risks tilted to the upside; labor risks broadly balanced.

Market reaction: Traders see a 78-79% chance of a hold at the October meeting, with a December hike still largely priced in (CME FedWatch).

Why it matters: The Fed is hiking into a growing economy with strong productivity and robust capital investment — a "resilience hike" rather than a "fear hike." The risk is that the market has not fully priced the terminal rate.

2. The Iran War Energy Shock — Eight Months In

The U.S.-Israeli war with Iran (started February 28, 2026) has fundamentally reshaped global energy markets.

Oil price trajectory:

• Brent started Q3 at $72/bbl (July 1) — the lowest since the war began
• Passed $100/bbl on July 23 after renewed strikes
• Peaked at $109/bbl futures / $132/bbl spot on September 15
• Currently ~$98/bbl (October 6)
• EIA forecast: $98/bbl average for 2026, $105/bbl Q4, $84/bbl for 2027

Supply disruptions:

• Strait of Hormuz (20% of global oil) severely disrupted
• Saudi East-West Pipeline attacked (3 pumping stations hit)
• U.S. blockade on Iranian oil exports
• Tanker attacks in Bab el-Mandeb Strait
• Ukraine drone strikes on Novorossiysk (Russia)
• Global inventories down ~400 million barrels YTD
• Production shut-ins: 4.5M bpd (Q4 2026) → 2.7M bpd (Q1 2027)

Workarounds emerging:

• Saudi East-West Pipeline restarted to Red Sea
• "Dark transits" (tankers disabling tracking)
• Ship-to-ship transfers
• Gulf oil flows (ex-Iran) at 81% of pre-war levels in September

Diesel crisis: U.S. retail diesel above $6/gallon in October, expected to ease to ~$4.50/gallon in 2027. Exceptionally tight diesel supplies are boosting crude demand as refiners maximize distillate output.

Inflation impact: Oil up 37%+ since the war started. This is the single largest driver of the Fed's inflation concern.

3. Bond Markets — Multi-Decade Highs

The 30-year Treasury yield has been on a historic run:

• May 19: 5.2% — highest since 2007
• August 18: 5.234% — highest since June 2007
• September: touched 5.702% — highest since 2002
• Currently: ~5.626% (October 6)

The 10-year yield is at 5.28%, also multi-year highs.

Drivers beyond Fed policy:

• $40 trillion federal debt with $1 trillion annual interest payments
• Foreign holders reducing Treasury holdings (June data)
• Hyperscaler bond issuance: Amazon, Alphabet, Meta, Microsoft, Oracle expected to issue ~$250B in 2026, $400B in 2027 — competing with government paper
• Global bond selloff: Japan 30-year at all-time record, Britain 30-year at 5.773% (highest in 30 years)

Treasury response: Doubled liquidity support buyback operations for longer-dated bonds (September 9 – November 4), which pulled the 30-year yield down ~10bp.

BofA survey: Most respondents expect the 30-year yield to reach 6% — which would be the highest since 1999.

4. Equity Markets — Record Highs Despite Headwinds

The S&P 500 and Nasdaq hit record highs on October 6:

• S&P 500: 7,840.66 (+0.86%)
• Nasdaq: 27,705.89 (+0.83%)
• Dow: 51,626.98 (+0.70%)

Q3 2026 earnings expectations:

• S&P 500 blended earnings growth: ~29.5-31% YoY (FactSet/LSEG)
• Tech sector EPS growth: 65% (up from 57% on June 30)
• Semiconductors: ~136% YoY growth expected
• Energy sector leading growth (war-driven)
• Mag-7: ~20% average growth; other 493 stocks: ~27% growth
• 2026 full year: 32.4% expected; 2027: 15.8%

Key earnings next week:

• Tuesday: JPMorgan, Goldman Sachs
• Wednesday: (banks continued), BlackRock, Johnson & Johnson, UnitedHealth
• Wednesday CPI: 3.6% headline expected, 2.5% core

The AI earnings engine:

• AI demand growth: 54% (contributed 20pp to Q2's 34% earnings surge)
• Micron delivered a knockout quarter
• Meta's Muse agent launch set off AI consumer e-commerce arms race
• GPU rental prices rising
• ISM manufacturing at 4.5-year high

The "peak earnings" concern: Ameriprise's Saglimbene: "We are kind of approaching peak earnings growth... every quarter we go, and they continue to spend, the hurdle rates get higher and the scrutiny gets larger."

Barclays' counter: "If earnings are growing at 30% and real rates rise 100bp, the earnings growth still has the upper hand."

5. Inflation — The Numbers That Triggered the Hike

September 2026 CPI (released October 15):

• Headline: 3.6% YoY (up from 3.4% in August)
• Monthly: +0.6% (above the 0.3% threshold)
• Core: 2.4% YoY, +0.2% monthly (smallest since start of year)

August 2026 CPI:

• Headline: 3.4% YoY
• Core: 2.4% YoY

The Fed's concern: While core is moderating, headline remains well above the 2% target. The energy shock from the Iran war is the primary driver. Shelter costs continue to rise (+0.4% monthly). The Fed's PCE inflation projection of 3.7% for 2026 is significantly above target.

Nowflation realtime gauge: 3.00% YoY as of September 17, with a 3-month annualized pace of +2.95%.

6. What to Watch This Week

1. Bank earnings (Tue/Wed): JPMorgan, Goldman Sachs — the first read on whether higher rates are compressing net interest margins or boosting them
2. September CPI (Wed): 3.6% headline expected — if it comes in hot, December hike odds rise further
3. Fed speakers: Any color on the terminal rate — Warsh has refused to give forward guidance
4. Oil: Any escalation in the Iran war could push Brent back above $100
5. 30-year Treasury: The 6% level is the line in the sand — a break above it would signal a structural repricing of long-duration assets

7. Synthesis

The U.S. economy is in an unusual configuration: the Fed is hiking rates into a growing economy, not a weakening one. The drivers are a war-driven energy shock and AI-driven capital spending boom. Equities are pricing in continued earnings growth (~30% in 2026), while bonds are pricing in a higher-for-longer regime with fiscal dominance concerns.

The key tension: if earnings growth decelerates as expected in 2027 (15.8%) while rates stay elevated, the equity risk premium compresses. The Barclays argument — that 30% earnings growth can absorb 100bp of real rate rise — works until it doesn't. The inflection point is when AI capex scrutiny intensifies and the "hurdle rate" problem bites.

For now, the market is shrugging off rate hikes because earnings are outrunning them. That dynamic has a shelf life.
