Commodity Markets Kyun Exist Karte Hain

Fundamental Problem: April mein ek wheat farmer ko September ke harvest price ka pata nahi hota. Agar harvest ke waqt prices crash ho gayi, toh woh bankrupt ho jaayega. Ek bread company ko future wheat costs ka pata nahi—bread prices set nahi kar sakti. Solution: futures contracts. Farmer aaj September ka wheat ek fixed price par bechta hai. Bread company khareed leti hai. Dono risk hedge karte hain. Traders profit ke liye doosri side lete hain, liquidity provide karte hain.

Teen Market Participants:

1. Hedgers: Producers/consumers jo prices lock karte hain (risk reduction)
2. Speculators: Traders jo price direction par bet lagate hain (profit motive, liquidity provide karte hain)
3. Arbitrageurs: Markets/time mein price differences exploit karte hain (prices ko efficient rakhte hain)

Chaar Major Commodity Categories

1. Gold & Silver (Precious Metals)

Gold ka Unique Role: Doosre commodities se alag, gold mein minimal industrial consumption (~10%) hai. Ye primarily ek monetary asset aur inflation hedge hai. Kyun?

• Inflation Hedge Mechanism: Jab currency ki purchasing power girती hai, gold ki intrinsic scarcity value preserve karti hai. Agar $100ne2000mein1ozgoldkharidaaur2020mein$1800 mein, toh gold ne dollar debasement ko "track" kiya.
• Negative Real Rates Gold ko Drive Karte Hain: Gold koi interest nahi deta. Jab real interest rates (nominal rate - inflation) negative ho jaate hain, cash/bonds hold karna real purchasing power khota hai. Gold attractive ban jaata hai. Gold ke opportunity cost ka formula:

First principles se derivation:

1. Shuru: Bonds mein invest kiya $1eksaalbaad$(1 + r_{\text{nominal}})$ return karta hai.
2. Lekin $\pi$ rate par inflation ka matlab hai woh dollar $(1+\pi {)}^{-1}$ goods khareed sakta hai.
3. Real purchasing power return: $(1+r_{\text{nominal}})/(1+\pi )\approx 1+r_{\text{nominal}}-\pi$ (chhote rates ke liye Taylor expansion).
4. Toh real return $\approx r_{\text{nominal}}-\pi$.
5. Agar negative hai, toh bonds real terms mein value kho dete hain → gold (zero yield lekin stable value) jeetta hai.

Ye step kyun? Approximation $(1+x)/(1+y)\approx 1+x-y$ tab valid hai jab $|x|,|y|\ll 1$, jo typical interest/inflation rates (2-5%) ke liye sahi hai. Exact formula: $r_{\text{real}}=(1+r_{\text{nominal}})/(1+\pi )-1$.

Silver ki Dual Nature: 50% industrial (solar panels, electronics), 50% monetary. Gold se zyada volatile—industrial demand swings price moves ko amplify karti hain.

Ye step kyun? Jab real rates positive ho gaye, toh zero-yield gold hold karne ka opportunity cost badh gaya. Investors interest-bearing assets ki taraf shift ho gaye.

2. Crude Oil (Energy)

Global Economic Barometer: Oil industrial economies ki lifeblood hai—transportation, plastics, chemicals. Demand GDP growth track karta hai. Supply geopolitically concentrated hai (OPEC+, Russia, US shale).

Do Benchmark Prices:

• WTI (West Texas Intermediate): US benchmark, light sweet crude (low sulfur, refine karna aasaan).
• Brent: Global benchmark, North Sea oil. Typically WTI se $2-5 premium (zyada transport costs, quality).

Supply-Demand Dynamics:

Derivation (stylized model):

1. Supply curve: Short-term supply inelastic hai (wells jaldi open/close nahi kar sakte). Long-term, price marginal producer ka cost cover karni chahiye (US shale breakeven ~$50-60/bbl).
2. Demand curve: Short-term bhi inelastic (gadiyon ko rooz gas chahiye). Long-term, zyada prices → efficiency, EVs.
3. Equilibrium: Intersection par, price market clear karta hai. Lekin OPEC cartel supply restrict kar sakta hai → competitive level se zyada price.
4. Risk premium: War, sanctions (Russia, Iran) → supply threat → premium. Agar 100M global mein se 2M bl/day at risk hai, toh inventory buffers ke hisaab se premium ~$5-15/bbl.

Ye step kyun? Formula dikhata hai ki oil "free market" nahi hai—ye cost floor + cartel manipulation + geopolitical shocks hai. Explain karta hai ki oil mahino mein 50%+ kyun swing karta hai.

Ye step kyun? Negative price ek futures market technicality (physical delivery squeeze) tha, oil "worthless" nahi tha. Spot oil positive raha.

3. Agricultural Commodities

Weather Volatility Driver Hai: US Corn Belt mein drought corn ko weeks mein 40% spike kar sakta hai. Oil ke unlike (storage saalon tak chalta hai), grains seasonal aur perishable hote hain.

Key Crops & Seasonality:

• Corn & Soybeans: April-May (US) mein lagaaye jaate hain, Sept-Oct mein harvest hote hain. Prices July-August mein peak karte hain (pre-harvest uncertainty). Harvest ke baad girte hain (supply market flood karti hai).
• Wheat: Multiple harvest cycles (US winter wheat May-June, spring wheat Aug-Sept). Global production (Russia, EU, US, Argentina).
• Coffee & Sugar: Tropical crops, long growing cycles (coffee trees mature hone mein 2-3 saal). Brazil frost = global price spike.

Derivation:

1. Maano US corn ka base yield = 180 bushels/acre. July mein 4-week drought (pollination stage) → 20% yield loss (empirical).
2. US global corn ka 35% produce karta hai. Global supply $\Delta Q/Q=0.35\times 0.20=7\%$ girti hai.
3. Demand elasticity ${ϵ}_d=0.2$ ka matlab hai 1% price increase → 0.2% demand decrease.
4. 7% shortfall clear karne ke liye: $\text{Price increase}=7\%/0.2=35\%$.

Ye step kyun? Low elasticity price swings ko amplify karti hai. Consumers "khaana skip" nahi kar sakte, isliye supply shocks ke liye huge price adjustments hoti hain.

Ye step kyun? Spike harvest se pehle expectation-driven tha. Jab actual yields pata chali (buri lekin catastrophic nahi), prices normalize ho gayi.

Commodity Futures Kaise Kaam Karte Hain

Example: Dec 2026 Gold Futures (symbol GCZ26)

• Contract size: 100 troy oz
• Current price: $2,400/oz
• Margin requirement: $10,000\text{ (5\% of}$240,000 contract value)
• Agar gold → $2,450,teraprofit:($2,450 - $2,400)\times 100=$5,000 on $10,000 margin (50% return!)
• Agar gold → $2,350,tum$5,000 lose karte ho (50% loss). Broker liquidate kar sakta hai agar margin deplete ho jaaye.

Contango vs Backwardation:

Derivation (No-Arbitrage Condition):

1. Strategy A: Aaj $S_0$ par commodity kharido, $T$ saal store karo (cost $c\cdot T$), financing cost $r\cdot T$.
2. Time $T$ par total cost: $S_0{e}^{(r+c)T}$.
3. Strategy B: $F_T$ par futures kharido, $S_0$ ko rate $r$ par invest karo.
4. No arbitrage: $F_T=S_0{e}^{(r+c-y)T}$.
5. Contango ($F_T>S_0$): Storage costs zyada, koi shortage nahi (normal). Futures price delivery time ke saath badhti hai.
6. Backwardation ($F_T<S_0$): Shortage ka dar → high convenience yield $y$ (physical hold karna valuable). Near-term delivery premium.

Ye step kyun? Formula dikhata hai ki futures "predictions" nahi hain—ye spot price + carry costs hain. Contango mein, futures roll karne se paisa kho jaata hai (har roll mein kam mein becho, zyada mein kharido). Backwardation mein faayda hota hai.

Price Drivers: 5 Forces

1. Supply Shocks

• OPEC cuts, weather disasters, mine strikes. Inelastic supply → bade price moves.

2. Demand Cycles

• GDP growth (oil, copper), seasonal (heating oil winter, cooling summer), long-term (EV transition oil demand reduce karti hai).

3. Currency Effects

• Commodities USD mein price hoti hain. Strong dollar → foreign buyers ke liye commodities mehengi → demand girti hai → prices girte hain.
• Formula: Agar USD basket ke mukable 10% appreciate kare, Europe se oil demand ~5% girta hai (elasticity ~0.5), prices ~10% down push karta hai.

4. Inventory Levels

• High stocks → bearish (abundant supply), low stocks → bullish (shortage risk).
• Days of Supply metric: Inventory / Daily Consumption. Oil < 30 days → tight market.

5. Speculation & Financialization

• 2000s se, commodities ek asset class ban gayi (diversification, inflation hedge). Index funds, ETFs (e.g., GLD, USO) billions hold karte hain. Trends amplify ho sakti hain.

Commodity Markets Mein Trading: Instruments

1. Futures Contracts (Professional)

• High leverage, daily settlement, professional liquidity.

2. ETFs (Retail)

• Physical-backed: GLD (gold), SLV (silver). Spot price closely track karte hain.
• Futures-based: USO (oil). Contango loss risk—contango mein futures roll karna returns ko bleed karta hai.

3. Commodity Stocks

• Gold miners (gold price par leverage), oil companies (leverage + dividend). Correlation imperfect—company risk overlay hoti hai.

4. Options on Futures

• Defined risk (premium paid), capped upside. Hedging ke liye useful.

Ye sahi kyun lagta hai: Textbooks mein gold "inflation hedge" hai. 1970s ka example (gold $35\to$850) memory mein sar pada hai.

Reality: Gold tab rise karta hai jab real rates negative hon aur currency trust erode ho. 1980-2000: Fed ne rates inflation se zyada badhaye (Volcker), real rates positive the. Bonds/stocks outperform kiye. Gold sirf tab hedge hai jab governments interest rates se zyada tezi se currency debase karti hain.

Fix: Real rates check karo. Agar 10-year TIPS yield > 1% hai, gold likely underperform karega. Agar < 0% hai, gold shine karta hai. Sirf CPI headline mat dekho.

Ye sahi kyun lagta hai: $F>S$ ek premium lagta hai. Market pessimism price kar raha hai?

Reality: Contango normal hai jab storage costs exist karti hain. Futures price carry costs diye hue no-arbitrage price hai. Shorting tab profit nahi deta jab tak contango fair value se zyada na ho ya market backwardation mein na jaaye.

Fix: Fair futures price calculate karo $F=S{e}^{(r+c)T}$ se. Agar observed $F$ zyada hai, tab contango excessive hai (potential short). Agar $F$ formula se match karta hai, toh koi edge nahi. Saath hi, contango mein futures short karne ka matlab hai har mahine tum loss mein roll karte ho (zyada mein wapas kharido, kam mein becho) jab tak spot tezi se na baadhe.

Ab, gold ek super-durable toy ki tarah hai jo kabhi toot nahi ta. Jab paper money (jaise Monopoly money) fake lagne lagti hai, sab ise chahte hain. Agar government bahut zyada money print kare, toh har dollar kam candy khareed sakta hai. Lekin gold rare hai—woh aur print nahi kar sakte—isliye woh apna "candy-buying power" rakhta hai. Isliye log gold khareedte hain jab unhein regular money par trust nahi hota.

Oil woh cheez hai jo gadiyon, trucks, aur planes ko chalati hai. Agar koi bada oil wala desh (jaise Middle East) mein war ho jaaye, toh kam oil aata hai. Lekin sab ko phir bhi apni gadiyon ke liye gas chahiye, toh price upar jaati hai. Jab pandemic ke baad (jaise COVID) sabki gadiyon ne phir kaam karna shuru kiya, achanak sab ek saath oil chahte the—price phir upar!

Wheat, corn, aur soybeans khaana hain. Agar mahino tak baarish nahi hoti (drought), toh paudhe mar jaate hain, aur bahut kam khaana hota hai. Lekin logon ko utna hi khaana chahiye, toh prices bahut upar jump karti hain. Farmers drought se nafrat karte hain, lekin traders tab paisa kama sakte hain jab weather bura dikhta hai aur prices upar jaane ki betting hoti hai.

#flashcards/stock-market

Commodity markets mein teen types ke participants aur unki motivations kya hain? :: 1) Hedgers (producers/consumers jo risk reduction ke liye prices lock karte hain), 2) Speculators (traders jo profit ke liye price direction par bet lagate hain, liquidity provide karte hain), 3) Arbitrageurs (markets ko efficient rakhne ke liye price differences exploit karte hain).

Commodities ke liye Days of Supply metric kya hai? :: Inventory ko daily consumption se divide karo. Market tightness indicate karta hai. Oil ke liye, < 30 days supply tight market signal karta hai (shortage risk, bullish). > 60 days oversupply suggest karta hai (bearish).
