The Basics
- Simple definition: The nominal exchange rate adjusted for price level differences between countries, measuring the real purchasing power of a currency.
- Core idea: It considers not just how many rupees per dollar, but what those rupees can actually buy in each country.
- Think of it as: The true competitiveness measure because it accounts for both currency value and relative prices.
What It Actually Means
The real exchange rate equals the nominal exchange rate multiplied by the domestic price level divided by the foreign price level. It measures the relative price of goods between countries. If the real rate rises, meaning appreciation, domestic goods become more expensive relative to foreign goods, which hurts exports and helps imports. If the real rate falls, meaning depreciation, domestic goods become cheaper, which boosts exports. Real appreciation can happen through nominal appreciation or higher domestic inflation. It is key to trade competitiveness.
Example
Suppose the dollar to rupee rate is 280. A Pakistani shirt costs Rs. 5,600 locally, so it costs $20 at the nominal rate. If a US shirt costs $25, Pakistan is competitive. However, if Pakistan inflation is 10 percent while US inflation is 2 percent, the real exchange rate appreciates, meaning the Pakistani shirt becomes relatively more expensive even if the nominal rate remains unchanged.
Why It Matters (2026)
The real exchange rate determines trade competitiveness. Pakistan’s real appreciation from higher inflation hurts exports even when the nominal rate remains stable. Understanding it helps assess whether a currency is overvalued or undervalued.
Don’t Confuse With
Nominal Exchange Rate, because the nominal rate is the raw rate, while the real rate adjusts for price differences.
