Trade-Weighted Exchange Rate Reflects Trade Partner Importance

Steps:

• Recall that a trade-weighted exchange rate measures a currency's value against a basket of others, weighted by trade volumes.
• Evaluate options: A focuses on export/import prices, not currency weighting.
• B addresses trade's GDP share, irrelevant to exchange rate calculation.
• C matches weighting by trade values with partners; D concerns balance of payments, not weighting method.

Why C is correct:

• By definition, it weights currencies by the proportion of a country's trade with each partner, capturing relative trade importance in the exchange rate index.

Why the others are wrong:

• A: Terms of trade involve price ratios, not exchange rate weighting.
• B: Trade-to-income ratio measures openness, not partner-specific weights.
• D: Current account balance indicates trade position, but doesn't determine weighting.

Final answer: C
