Real Effective Exchange Rate (REER)
"A trade-weighted, inflation-adjusted index of a currency's value against a basket of trading partners' currencies."
The Real Effective Exchange Rate is a weighted average of a currency's value against a basket of major trading partners' currencies, adjusted for relative inflation. Unlike the Nominal Effective Exchange Rate (NEER), which is trade-weighted but not inflation-adjusted, the REER captures external price competitiveness. A REER above 100 (relative to a base year) suggests the currency is overvalued and exports are less competitive, while a value below 100 suggests undervaluation. The RBI compiles REER and NEER indices for the rupee.
GS3 (external sector, exchange rate, competitiveness). Prelims tests the REER versus NEER distinction and the RBI as compiler. Mains uses REER to assess export competitiveness and currency management. Anchor: through 2025-26 debate over whether the rupee was overvalued on a REER basis fed into discussions on export competitiveness amid global tariff uncertainty.
- 1 Trade-weighted, inflation-adjusted measure of currency value
- 2 Differs from NEER, which is not adjusted for inflation
- 3 A value above 100 signals overvaluation and weaker export edge
- 4 A value below 100 signals undervaluation
- 5 Compiled by the RBI for the Indian rupee against a currency basket
- 6 Used to gauge external competitiveness, not day-to-day trading
Discussion of an elevated rupee REER through 2025-26 sharpened the debate on export competitiveness as global tariff tensions pressured Indian shipments.
