history → ETFs → futures → price drivers → real examples → practice. Designed for quick learning.
A) Gold Quick Facts
Units
Troy ounce (oz t). 1 kg ≈ 32.1507 oz t. USD per oz t quotes.
Markets
Spot (LBMA OTC), Futures (COMEX: GC 100 oz, MGC 10 oz), ETFs (GLD, IAU, GLDM).
Why hold?
Inflation & crisis hedge, diversification (low corr to stocks/bonds), USD hedge.
B) History: Gold Standard → Bretton Woods → 1971 Break → Free Float
C) Gold vs GLD (concept) + Real Return
Real Return Calculator
Real return = ((1+nom)/(1+CPI)) − 1 = 3.88%
D) Gold ETFs — Real Examples & Classroom Recommendations
SPDR Gold Shares (GLD)
- Type: Physically backed grantor trust
- Expense ratio: ~0.40%
- Pros: Very liquid, tight spreads, long track record
- Cons: Higher fee vs. peers; collectible‑style tax treatment may apply (U.S.)
iShares Gold Trust (IAU)
- Type: Physically backed grantor trust
- Expense ratio: ~0.25%
- Pros: Lower fee than GLD; solid liquidity
- Cons: Slightly wider spreads than GLD in thin hours
SPDR Gold MiniShares (GLDM)
- Type: Physically backed (lower share price)
- Expense ratio: ~0.10%
- Pros: Very low fee; small share price ideal for students
- Cons: Liquidity smaller than GLD/IAU; may have slightly wider spreads
E) Gold Futures (COMEX) — Pros/Cons & Realistic Examples
Pros & Cons
- Pros: Efficient leverage; direct exposure; easy to short; near‑24h trading.
- Cons: Mark‑to‑market (margin calls); contract months & rolls; amplified losses; requires futures permissions.
Contract Specs (common)
- GC: 100 oz per contract. Tick = $0.10/oz → $10 per tick.
- MGC: 10 oz per contract (1/10 GC). Scaled P/L.
- Margin: Initial & maintenance set by the exchange/broker (varies over time).
Interactive Futures P/L
P/L: $25,000 (excludes commissions/fees)
Return on Margin: 277.8%
Realistic Example #1 — Hedging (Jeweler)
A jeweler holds ~200 oz inventory. To hedge near‑term price drops, they could short 2× GC contracts (≈200 oz). If gold falls $50/oz, futures profits ≈ $10,000 can offset inventory losses.
Realistic Example #2 — Speculating (Student‑size)
Use MGC (10 oz). Long 1 MGC @ $1,980 → sell @ $1,995 ⇒ gain = $15/oz × 10 oz = $150 (ignoring fees). Good for demos with controlled risk.
F) Gold Price Drivers — Interactive Sandbox
Move the sliders (class exercise)
Heuristic Forecast (Toy Model)
Gold prefers lower real yields & a weaker USD; rises with inflation fears, central‑bank buying, geopolitics, and ETF inflows.
Model signal (12m): Bullish • Expected move: +8.4% (classroom heuristic, not investment advice)
G) Explanations (Plain Language)
Real rates (TIPS)
Lower real yields → gold more attractive (opportunity cost falls). Higher real yields tend to pressure gold.
USD strength
Gold is priced in USD; a stronger dollar often weighs on gold (costlier for non‑USD buyers).
Inflation
Expectations matter more than current CPI; credibility of policy influences demand.
Central‑bank buying
Reserve diversification & FX/inflation hedging; strong official demand can support prices on dips.
Jewelry & tech demand
India/China jewelry seasonality; electronics is smaller but steady demand.
Supply & recycling
Mine supply grows slowly; high prices stimulate recycling which may cap spikes.
H) Compare: ETF vs Futures vs Physical
ETF (GLD/IAU/GLDM) | Futures (GC/MGC) | Physical (coins/bars) | |
---|---|---|---|
Access | Easy via brokerage | Futures permissions | Dealer/vault |
Leverage | No | Yes (margin) | No |
Costs | Expense ratio; small spread | Commissions/exchange; financing via margin | Premiums; storage/insurance |
Tracking | Spot gold (net fees) | Front‑month futures (roll) | Spot (less liquid) |
Taxes (U.S.) | Often collectible‑like | 1256 (60/40); varies | Collectibles |
Use‑case | Investors | Hedgers, traders | Store of value |
I) Practice — Short Questions
- Under Bretton Woods, why was the USD central? What ended in 1971?
- List three reasons gold can rise even if CPI falls YoY.
- Compute P/L: Long 2× GC @ 1950; settle 1972. What is $ P/L? Return on $18,000 margin?
- GLDM 0.10% ER on $10,000 for 5y (ignore compounding): about how much in fees?
- Real yield −1% → +1%, USD +5%, CB buying steady, geopolitics calm. Qualitative signal?
