Futures

What futures contracts specify

Every futures contract defines:

• Underlying — what's being bought or sold (oil, wheat, S&P 500 index, Bitcoin).
• Quantity — fixed contract size (1,000 barrels of oil; 5,000 bushels of wheat; $50 × index value for E-mini S&P).
• Delivery/expiration date — when the contract settles.
• Settlement method — physical delivery (oil, agricultural products) or cash settlement (most financial futures).

Contracts are standardized so they can trade on exchanges (CME, ICE, Eurex) with deep liquidity. Unstandardized variants are called "forwards" and trade over-the-counter between specific parties.

How futures pricing works

Futures prices reflect expectations of the underlying price at expiration:

Futures Price ≈ Spot Price + Cost of Carry − Income from Holding

For commodity futures: cost of carry includes storage and financing; for financial futures, just financing minus dividends.

When futures trade above spot, the curve is in contango (typical for commodities with storage costs). When below spot, backwardation (often happens during shortages or stress).

Spot prices and futures prices converge at expiration. This convergence is what allows arbitrage to keep them aligned beforehand.

Why people use futures

• Hedging. A wheat farmer sells futures to lock in next harvest's price. An airline buys oil futures to fix fuel costs. A multinational uses currency futures to hedge revenues. Producers and consumers transfer specific risks to parties willing to bear them.
• Speculation. Taking directional bets with high leverage. Most retail futures activity falls here.
• Arbitrage. Cash-and-carry strategies, calendar spreads, basis trades.
• Asset allocation. Index futures let large managers gain or hedge equity exposure efficiently.

Margin and leverage

Futures don't require paying full notional value upfront. Instead:

• Initial margin — deposit required to open position. Typically 5-15% of notional value.
• Maintenance margin — minimum balance to keep position open.
• Margin calls — if balance falls below maintenance margin, additional deposits required (or position liquidated).

Mechanically, this provides leverage. A $5,000 deposit might control $100,000 notional in commodity futures, providing 20x leverage. Profits and losses scale accordingly.

Notable historical futures markets

• CBOT (Chicago Board of Trade) — founded 1848, the original modern futures exchange. Agricultural futures.
• CME (Chicago Mercantile Exchange) — financial futures (S&P 500, Eurodollars, currencies). Now part of CME Group along with CBOT.
• NYMEX (New York Mercantile Exchange) — energy and metals futures.
• ICE (Intercontinental Exchange) — global futures including Brent crude, sugar, and various financial products.

All major US futures exchanges now operate electronically, though some open-outcry pits persisted into the 2010s.

Bitcoin and crypto futures

Crypto futures have grown into a major segment:

• CME Bitcoin futures — launched 2017, the first regulated US Bitcoin futures. Cash-settled.
• CME Ether futures — launched 2021.
• Crypto-native perpetuals — the dominant crypto derivative. Don't expire, settle continuously through funding rate payments.
• Spot ETF flows combined with futures activity have produced sophisticated basis-trade markets in BTC and ETH.

The crypto perpetuals market has innovated beyond traditional futures. Centralized exchanges like Binance, OKX, Bybit and on-chain venues like dYdX, Hyperliquid handle hundreds of billions in daily volume — at times more than spot crypto trading.

Risks specific to futures

Beyond the underlying price risk:

• Leverage amplifies losses. Small adverse moves can wipe out the margin deposit and trigger calls for more.
• Forced liquidation. Falling below maintenance margin can result in immediate position closure at unfavorable prices.
• Roll cost. Rolling expiring futures into new contracts has cost in contango markets — popular long-only commodity strategies have struggled with sustained negative roll yield.
• Limit moves. Futures markets impose daily price limits; during extreme moves, you can't exit at any price.
• Counterparty risk — historically minimal for exchange-cleared futures (central counterparty absorbs default risk), but real for OTC forwards and some specialized products.

Why retail should approach with caution

Futures are powerful tools that reward precision and punish carelessness. Most retail futures activity is leveraged speculation that produces large losses on average. Even skilled traders can be wiped out by single overnight moves with high leverage.

For most investors, broad index investing produces better long-run risk-adjusted returns than active futures trading. For those genuinely interested in derivative strategies, starting with small position sizes and well-understood strategies (covered calls, protective puts) is wiser than starting with leveraged directional bets.

Where futures actually serve everyone

Even non-participants benefit from futures markets:

• Price discovery — futures markets contribute to global price formation for commodities and assets. Producers and consumers benefit from the resulting price signals.
• Risk transfer — the existence of futures markets lets producers, consumers, and intermediaries hedge risks they couldn't otherwise lay off.
• Capital allocation — futures-derived signals inform investment, inventory, and production decisions throughout the broader economy.

The visible activity of speculators in futures markets often obscures the deeper economic role of providing liquidity for genuine hedgers. Both functions matter.
