Why in news: On 8 October 2026 the People's Bank of China said in a policy paper that it has no need or intention to weaken the yuan.

NEER and REER: how the RBI measures the rupee's value
Illustration (AI-generated)

The Nominal Effective Exchange Rate (NEER) is an index of the rupee's weighted average value against the currencies of India's trading partners. The Real Effective Exchange Rate (REER) adjusts it for inflation differences. The Reserve Bank of India publishes both for 40-currency and 6-currency baskets. On 8 October 2026, China's central bank rejected claims that the yuan is undervalued.

In short

The Nominal Effective Exchange Rate (NEER) is a trade-weighted index of the rupee against partner currencies; the Real Effective Exchange Rate (REER) adjusts it for relative prices.

Judge the rupee by its REER, not the dollar rate alone: lasting export competitiveness rests on low inflation and rising productivity, not on depreciation.

Why it matters

An Indian garment exporter competes with sellers from Bangladesh, Vietnam and China, and is paid by buyers in many currencies. Suppose the rupee holds steady against the dollar while prices in India rise faster than prices abroad. Indian goods then cost foreign buyers more, though the headline rate has not moved. The REER catches this. When it rises, exports lose price competitiveness and imports get cheaper; when it falls, exporters gain. Economists therefore read the REER, and not the rupee-dollar rate alone, to judge whether the rupee is overvalued or undervalued. The same logic explains why the value of the currency of a large trading partner such as China matters to Indian industry.

Prelims pointers

  • NEER: an index of the weighted average of the rupee's bilateral exchange rates against trading partners' currencies; it makes no adjustment for prices.
  • REER: the NEER adjusted by relative prices, India's price level against its partners'; it reflects both the nominal rate and the inflation differential.
  • Direction: a rise in the RBI's NEER or REER index is an appreciation of the rupee; a rise in REER means a loss of export price competitiveness.
  • Compiler: the Reserve Bank of India. Both indices are geometric weighted averages, and rates are worked out through the Special Drawing Right of the International Monetary Fund as numeraire.
  • 6-currency basket: US dollar, euro, pound sterling, Japanese yen, Chinese renminbi and Hong Kong dollar.
  • Bank for International Settlements: publishes effective exchange rates for 64 economies; its weights come from manufacturing trade and count third-market competition; its REER uses consumer prices.
  • Balassa-Samuelson effect: a country whose productivity in traded goods grows faster than its partners' sees its real exchange rate appreciate.
  • The Monetary Authority of Singapore uses the NEER of the Singapore dollar as the operational target of its monetary policy.

Practise a UPSC-style question

With reference to the effective exchange rates of the Indian rupee, consider the following statements:

1. The Nominal Effective Exchange Rate adjusts the rupee's exchange rate for the difference in inflation between India and its trading partners.

2. The indices of the Nominal and Real Effective Exchange Rates of the rupee are compiled and published by the Department of Economic Affairs.

Which of the statements given above is/are correct?

  1. (a) 1 only
  2. (b) 2 only
  3. (c) Both 1 and 2
  4. (d) Neither 1 nor 2
Show the answer

Answer: (d) Neither 1 nor 2

1 is incorrect: the NEER is a weighted average of nominal bilateral exchange rates with no price adjustment; the REER is the index that adjusts for relative prices. 2 is incorrect: the Reserve Bank of India compiles both indices and publishes them in the RBI Bulletin, not the Department of Economic Affairs.
