Definition
Real Effective Exchange Rate (REER)
REER is a trade-weighted index of a currency against a basket of partner currencies, adjusted for inflation differences, measuring true competitiveness rather than a single bilateral rate.
USDINR alone doesn't tell you whether the rupee is overvalued; the REER does, by comparing the rupee against a basket of trading-partner currencies and netting out inflation gaps. The RBI publishes 40-currency and 6-currency REER indices.
When the rupee's REER rises well above 100 (its base), it signals overvaluation that can hurt exports, even if USDINR looks stable. Policymakers watch REER to judge whether real competitiveness is eroding despite a steady nominal rate.
