Devaluation vs Revaluation

Deliberate acts, not market moves

Devaluation is an official, deliberate *lowering* of a currency's value under a fixed or pegged exchange-rate system; revaluation is the official *raising* of it. The crucial point is that both are government decisions — a country with a pegged currency resets the peg by decree. This is fundamentally different from depreciation and appreciation, which are *market-driven* movements that happen under a floating exchange rate, with no single official act behind them.

India's two famous devaluations

India, which once pegged the rupee, has carried out major devaluations at moments of crisis. In 1966, facing a severe foreign-exchange shortage and external pressure, the government devalued the rupee by about 36.5%, from roughly ₹4.76 to ₹7.50 per dollar in a single official move. The second came in 1991, India's last true devaluation — a roughly 18-19% cut, executed in two steps over a few days in July, when reserves had dwindled to barely a few weeks of import cover. That devaluation was part of the historic liberalisation reforms that opened the Indian economy.

Why the terms no longer apply to India

Here is the key modern point: India no longer devalues or revalues the rupee, because it no longer runs a fixed peg. After 1991, India moved to a managed (or "dirty") float, where the market sets the rupee's level day to day and the RBI intervenes only to smooth volatility. So when the rupee weakens today, that is depreciation — a market outcome — not devaluation. Commentators and headlines frequently confuse the two, but the distinction matters: one is a policy decree under a peg, the other is the market at work under a float.

Why it matters

Getting this right sharpens how you read currency news. If you see "devaluation" applied to the rupee today, it is almost certainly a misnomer — the correct word is depreciation. The terms still apply to countries that maintain pegs (and to historical episodes like 1966 and 1991), but for modern India, the rupee floats. Understanding the difference helps you judge whether a currency move reflects a one-off government decision or the ongoing pressures of trade, inflation and capital flows that drive a managed float.
