Why People Trade Forex (Hedging, Speculation, Arbitrage) 🎯

Beginner⏱️ 11 min📅 2025

$7.5 trillion trades daily in the forex market. Why? Not everyone is trying to profit. Multinational corporations hedge to protect margins. Central banks intervene to stabilize currencies. High-frequency traders arbitrage microsecond inefficiencies. But one group drives 90%+ of volume and creates every tradable trend: Speculators. Understanding who trades, why they trade, and which group moves the market is the difference between following random noise and riding institutional momentum.

Welcome to Lesson 6

You've mastered Market Structure, Sessions, and Liquidity Providers. You know WHAT moves and WHEN it moves. But here's the missing piece:

WHY does $7.5 trillion change hands every day?

💡

The Professional Difference: Retail traders see price movement and chase it blindly. Professionals ask: "What's the INTENT behind this flow? Is this hedging (temporary), speculation (tradable trend), or arbitrage (instant correction)?" They analyze order flow, positioning data (COT reports), and session timing to identify speculative momentum. Intent determines outcome.

The Volume Breakdown

Daily Forex Market ($7.5 Trillion):

  • Speculation: ~$6.75 trillion (90%)
  • Hedging: ~$700 billion (9.3%)
  • Arbitrage: ~$50 billion (0.7%)

Key Insight: When you analyze a chart, you're primarily observing speculative flow. Hedging adds temporary volatility. Arbitrage ensures price consistency. But speculation creates the trends you trade.

2Chapter 2: Hedging - Risk Minimization
⏱️ ~3 min

Hedging is the process of taking an offsetting position to protect against adverse exchange rate fluctuations. It's insurance, not profit-seeking.

How Corporate Hedging Works

Example: US Multinational Corporation (TechCorp)

Scenario:

  • TechCorp manufactures in the USA
  • Sells products in Europe
  • January: Agrees to sell €10 million worth of goods
  • Payment due: April (3 months later)

The Exposure:

Current Exchange Rate (January):

  • EUR/USD = 1.1000
  • Expected revenue: €10M × 1.1000 = $11 million

The Risk:

If Euro weakens by April:

  • New rate: EUR/USD = 1.0500
  • Actual revenue: €10M × 1.0500 = $10.5 million
  • Loss: $500,000 (4.5% revenue erosion)

The Hedge (Risk Elimination):

TechCorp's Action (January):

  1. Immediately sells €10 million forward at 1.1000
  2. Locks in exchange rate for April delivery
  3. Uses Forward Contract or FX Option

Result (April):

  • Forward contract settles at 1.1000
  • TechCorp receives exactly $11 million
  • Revenue locked, margins protected
  • No currency risk

Hedging Impact on Markets

Volume Characteristics:

  • Large size: Corporate hedging involves millions/billions
  • Non-directional: For every hedger selling EUR, another is buying
  • Time-bound: Hedges expire, pressure reverses
  • Temporary impact: Price moves, then reverts after order fills

Trading Implication:

Red Flag for Traders:

  • Sudden 30-50 pip spike during low liquidity
  • No fundamental catalyst
  • Likely hedging flow (corporate repatriation)
  • Don't chase it—will reverse once order completes
3Chapter 3: Speculation - The Engine of Profit
⏱️ ~3 min

Speculation is trading currency with the explicit goal of profiting from anticipated price movements. Speculators bet on direction.

The Speculative Ecosystem

Who Speculates:

1. Hedge Funds

  • Deploy billions in leveraged positions
  • Trade macro themes (interest rate differentials)
  • Hold positions for weeks/months
  • Impact: Create sustained trends

2. Proprietary Trading Desks (Banks)

  • Trade bank's own capital
  • Exploit short-term inefficiencies
  • Use algorithmic strategies
  • Impact: Add intraday volatility

3. Central Banks (Yes, They Speculate)

  • Intervene to influence currency value
  • Build/defend exchange rate levels
  • Impact: Massive directional pressure

4. Retail Traders (You)

  • Trade technical patterns, news events
  • Use leverage to amplify smaller capital
  • Impact: Provide additional liquidity

The Trend Formation Process:

Step 1: Fundamental Catalyst
(Fed hints at rate cuts = weaker USD expected)

Step 2: Institutional Analysis
(Hedge funds analyze, build conviction)

Step 3: Position Accumulation
(Funds buy EUR/USD in size over days)

Step 4: Trend Develops
(EUR/USD rises 300+ pips over 2 weeks)

Step 5: Retail Participation
(Trend followers join, momentum continues)

Step 6: Position Exit
(Funds close, trend exhausts, reversal begins)

Your Role: Identify when institutions are accumulating speculative positions and ride the trend.

4Chapter 4: Arbitrage - Market Efficiency
⏱️ ~2 min

Arbitrage is a low-risk strategy that profits from temporary price discrepancies for the same asset across different markets.

The Modern Reality: HFT Dominance

Why Retail Can't Arbitrage:

Speed Requirements:

  • Opportunity lasts: 0.001 seconds (1 millisecond)
  • Human reaction time: 200+ milliseconds
  • You're 200x too slow

Technology Requirements:

  • Co-located servers (next to exchange)
  • Direct market access (DMA)
  • Sub-millisecond execution
  • Cost: $100,000+ per month

HFT Advantage:

  • Detects discrepancy in 0.1ms
  • Executes in 0.2ms
  • Profits captured before price updates on your screen

Arbitrage's Critical Role

Why It Matters (Even Though You Can't Do It):

Market Efficiency:

  • HFT arbitrage ensures global price consistency
  • EUR/USD is the same price across all major LPs (within 0.1 pip)
  • You get fair pricing wherever you trade

Professional Takeaway: Thank HFT for making your broker's price reliable. You can't arbitrage, but you benefit from those who do.

⏱️ ~4 min

Summary

The forex market is driven by three key intentions:

Key Principles (0/3)

Hedging (9.3% of volume)
Goal: Reduce/eliminate currency risk, Participants: MNCs, portfolio managers, Impact: Temporary volatility, non-directional, Your response: Avoid trading these moves
Speculation (90% of volume)
Goal: Profit from directional price moves, Participants: Hedge funds, central banks, retail traders, Impact: Sustained trends, tradable momentum, Your response: Identify and ride these trends
Arbitrage (0.7% of volume)
Goal: Profit from price discrepancies, Participants: HFT firms, Impact: Ensures market efficiency, Your response: Appreciate it, can't exploit it

The Critical Insight: 90% of volume is speculation, and 100% of tradable trends come from speculation. Your job is to filter out hedging noise and align with speculative momentum.


Frequently Asked Questions

Q1: Is retail trading considered hedging or speculation?

Retail trading is 100% speculation.

Why:

  • Goal: You trade to profit from price movements
  • No underlying exposure: You don't own a business needing currency conversion
  • Directional bets: You go long or short based on analysis

Professional Identity: Embrace this. You're a speculator. Your edge comes from aligning with larger speculators (institutions) who create the trends you ride.

Q2: Why is the volume of arbitrage so low today?

Technology killed arbitrage opportunities.

Today (2024):

  • HFT algorithms, co-located servers
  • Price updates every 0.001 seconds
  • Arbitrage opportunities last 0.01-0.1 seconds
  • Only algorithms can exploit them
  • Arbitrage volume: less than 1% of market

Quiz

Which motive is responsible for creating sustained price trends and the majority of daily forex volume?

A US-based car manufacturer selling Yen received from Japanese sales back into USD is an example of:

What is the fundamental goal of a trader engaging in Hedging?

Why is two-currency arbitrage no longer viable for retail traders?

How can you identify if a spike is likely speculative (tradable) or hedging (noise)?


Call to Action

You now know the three fundamental forces that move the market. Your focus must remain on the largest—Speculation.
