What a strong dollar does to your portfolio

The dollar is the common denominator of global finance. A strong-dollar trend does not only affect
USD pairs — it touches nearly everything in your book.

1. Why the dollar matters this much

• Most international trade is settled in dollars.
• Commodities — oil, gold, metals, agricultural goods — are priced in dollars.
• Much emerging-market sovereign and corporate debt is borrowed in dollars.

Each of those creates its own transmission channel when the dollar strengthens.

2. The effect on commodities

A strong dollar makes commodities dearer for buyers in other currencies, reducing demand. Gold, oil
and industrial metals usually come under pressure.

The relationship is real but not absolute: if supply is disrupted or haven demand spikes,
commodities can rise alongside the dollar.

3. The effect on emerging markets

The strongest channel and the least discussed. Countries and companies that borrowed in dollars find
their debt burden growing in local-currency terms. That tightens capital flows, pressures the local
currency, and in severe cases leads to a crisis.

For a trader, the consequence is that emerging-market currency pairs tend to come under pressure
together during a strong-dollar cycle.

4. The effect on US equities

Large US companies earn a substantial share of revenue abroad. A strong dollar shrinks that revenue
when translated back, affecting reported earnings. This regularly shows up during results season.

5. Duplicated risk in a retail book

The most practical point for your own account: a great many positions that look different are the
same bet on the dollar.

• Long EUR/USD, long
  GBP/USD, long
  AUD/USD → three short-dollar positions.
• Add long gold → also inverse to the dollar.
• Add long an index → risk appetite, usually aligned with a weak dollar.

Five positions, one risk. When the dollar strengthens unexpectedly, all five lose.

6. How to control it

• Keep the dollar index chart open beside
  whatever you trade. It tells you immediately whether the move you are seeing is a dollar story or the
  other currency’s.
• Measure risk by group, not by position.
• Cap total dollar-related risk — say 2–3% of the account — rather than counting
  trades.
