3/15 Weekly U.S. Stock Market - War, Interest Rates, Commodities
March 15, 2026 Weekly Market Analysis
## This Week's Key Theme: "A Week Where Only Commodity Price Beneficiaries Survived Amid War and Rate Concerns"
This week (based on March 10-15 close), the U.S. stock market was generally weak overall. Of 11 sectors, 10 declined, with only Energy holding at +3.5%.
Summarizing the background in one line:
> As concerns about Iranian war and resulting commodity and inflation uncertainties, along with uncertainty about "when will rates be cut," intensified, cyclical, consumer, and financial stocks were hammered, while only stocks benefiting from commodity price increases like materials, fertilizers, and chemicals survived. (apnews.com)
- Iran war news: Depending on when and how the war ends, oil, fertilizer, and chemical prices are fluctuating significantly. If the war drags on, Middle Eastern supply disruptions extend and prices rise; if not, they plunge. (home.saxo)
- Rate (Fed) uncertainty: As concerns grow that inflation (prices) could be stimulated again, the market is tilting toward "the Fed won't be able to cut rates quickly." Delayed rate cuts pose a burden on growth stocks and cyclical stocks.
- Company-specific stories: Energy and materials sides are strong due to commodity price benefits combined with production capacity constraints, while companies with high debt (Paramount Skydance) or high economic sensitivity (cruises, travel, retail) were heavily shaken. (tikr.com)

## Sector Performance: Energy Up, Everything Else in Retreat
### 1) Energy: The "Relative Winner" of War and Supply Uncertainty
- 10-day return: +3.50% (only positive sector)
- 30-day: +16.0%, 120-day: +34.05% - maintaining strong upward trend in both short and medium term
Why did it rise?
- As Iranian war and Middle East tensions intensify, concerns that "supplies could be cut anytime" are pushing up oil prices and refining margins (profits refiners make from processing oil). (apnews.com)
- The more uncertain supplies are, the greater the pricing power of refiners and energy producers, and as profit forecasts rise, stock prices rise in tandem.
Representative stock movements
- Marathon Petroleum (MPC) +14.11%, APA +13.50%, Valero (VLO) +12.68% - refining and exploration companies rose strongly.
Why does this matter to me?
- Oil and energy prices directly connect to living costs through gas station fuel prices, airfares, and logistics costs.
- Energy stocks being strong is a signal that the market sees "oil prices likely won't fall easily," making it an important clue for reading future inflation and rate paths.

### 2) Materials: Fertilizers and Chemicals Strike Back
- 10-day: -4.43% (overall sector decline, but core stocks surge)
- 30-day: +1.86%, 120-day: +18.83% → medium-term upward trend continues
Core story: Fertilizer and petrochemical price rally
- CF Industries (CF) +30.53%: A nitrogen fertilizer company benefiting from growing supply concerns for fertilizer raw materials (ammonia, urea) due to Iranian war and Middle East tensions, and CF is gaining from its "cost competitiveness" advantage in manufacturing fertilizers from cheap gas in North America. (tikr.com)
- LyondellBasell (LYB) +27.22%, Dow (DOW) +19.17%: Petrochemical and plastic materials companies
- Previous supply disruptions from winter storms,
- Tight inventory (inventory shortage),
- Combined with RBC and other securities companies' upward price target and investment opinion upgrades, stock prices are being rapidly re-rated. (247wallst.com)
Why does this matter to me?
- Fertilizer prices lead to food prices, and petrochemical prices lead to plastic, packaging, and auto part prices.
- These companies being strong shows the market's worry that "inflation pressure (especially food and household items) could rise again."

### 3) Financials: Caught Between Rates, Debt, and Risk Assets
- 10-day: -5.41%, 30-day: -9.69%, 120-day: -7.99% → weakness continues in both short and medium term
Why was it weak?
1. Rate cut delay concerns
- War and commodity price uncertainty increase inflation re-acceleration possibilities, leading to concerns that "the Fed can't easily cut rates."
- The longer rates stay high, the more weakened loan demand, increased default risk, and reduced capital markets activity (IPOs, bond issuances, etc.) burden financials.
2. Crypto and alternative asset volatility
- Some like Coinbase (COIN) +11.19% performed well due to fee benefits from surging cryptocurrency trading, but it wasn't enough to change overall financial sector sentiment.
Why does this matter to me?
- Financials most sensitively reflect economic vigor and credit cycles (borrowing and repayment flows).
- This sector being weak over 30 and 120 days signals the market is taking "growth slowdown + debt burden" quite seriously.

### 4) Consumer (Cyclical and Defensive): Zipping Wallets Priced in Early
#### Consumer Cyclical
- 10-day: -8.31%, 30-day: -7.23%, 120-day: -5.01% → continued downtrend
- Representative weak stocks:
- Carnival (CCL) -23.93%, Norwegian Cruise Line (NCLH) -23.88%: Cruises are completely "travel and leisure cycle-sensitive." With war uncertainty, oil volatility, and growth slowdown concerns combined, psychology of "cut travel and cruises first" is reflected.
- Other travel, appliance, and discretionary consumption (luxury, leisure) companies were generally weak.
#### Consumer Defensive
- 10-day: -8.31%, 30-day: +0.15%, 120-day: +4.93%
- Short-term weakness, but still plus over the 120-day medium term, showing defensive characteristics.
- Within this, food and grain distribution companies like Kroger (KR) +10.79%, ADM +4.26%, Bunge (BG) +3.38% were relatively strong.
## Final Session (24H): Mixed with Defensive Stocks Recovering Slightly
Based on final trading day (24-hour performance):
- Only 4 of 11 sectors in plus.
- Utilities strongest at +1.04%, Energy nearly flat at -0.01%.
- Materials showed -1.68% with profit-taking.
Simplified:
> "The market beaten down all week caught its breath on the final day, with some funds shifting to defensive stocks like utilities."

## Next Week's Focus Points: 3 Important Questions for Me
1. War-related news: Will commodity, fertilizer, and chemical prices rise further or stabilize?
- If positive news on ceasefire or negotiations emerges, energy, fertilizer, and chemical rally pace could slow,
- If tensions escalate, living cost and inflation concerns could deepen.
2. Fed and inflation indicators: Will rate cut expectations revive?
- Depending on inflation indicators and Fed officials' remarks next week,
- Market expectations for "number of rate cuts this year" could shift dramatically.
- If prices show large re-acceleration, growth stocks, real estate, and consumer stocks could face another round of burden.
3. Earnings and guidance: What does "ground-level economic feeling" from companies show?
- Just because commodities and raw materials rise doesn't mean all companies profit.
- How successful companies actually are at "cost pass-through (price increases),"
- How they adjust margin (profit margin) forecasts is the key to next rally or pullback.

In summary, this week was "Energy and Materials vs. Everything Else" confrontation. I'd suggest reviewing your portfolio's commodity and energy weighting and the weighting of cyclical consumer and high-debt companies.
