Managed floating
Also called: Dirty floating · Topic: Balance of Payments and Exchange Rates · NCERT: Class 12, Ch 6 "Open Economy Macroeconomics"
Meaning
Managed floating (also called dirty floating) is an exchange-rate regime where the market mostly sets the rate, but the central bank buys and sells foreign currencies to slow down sharp movements. It does this without fixing any particular level.
- It sits between a fixed rate and a free float.
- Because the central bank steps into the market, official reserve transactions ≠ 0. Official reserve transactions are the central bank's purchases and sales of forex, recorded in the Balance of Payments (BoP).
- It matters because India follows it. It explains how the RBI uses its forex reserves to protect traders, borrowers and prices from wild swings in the rupee.
Explanation
How it works
- Exchange rate: the price of one currency in terms of another. In India it is written as ₹ per $.
- ₹/$ rises (e.g. ₹50 → ₹70): the rupee is weaker.
-
₹/$ falls: the rupee is stronger.
-
In a managed float, the demand for and supply of dollars decide the rate most of the time.
- The central bank steps in only when movements become too fast or disorderly. This is called forex intervention (the central bank buying or selling forex to influence the rate or reduce volatility).
- Rupee falling too fast → the RBI sells $
- More dollars come into the market.
- The fall in the rupee slows down.
-
Forex reserves go down.
-
Rupee rising too fast → the RBI buys $
- Extra dollars are taken out of the market.
- The rise in the rupee slows down.
-
Forex reserves grow.
-
Forex reserves (foreign currency, gold and similar assets held by the RBI) are the "ammunition" for this. Without enough reserves, a central bank cannot manage the float.
Tools of intervention
- Spot operations: buying or selling $ for immediate delivery.
- Forward operations: contracts to buy or sell $ at a future date. When the RBI sells $ forward, forward premia cool down. The forward premium is the extra price of a dollar bought for future delivery.
- Buy/sell swaps: the RBI buys $ now and agrees to sell them later, or does the reverse. This lets it manage the rupee's liquidity (how much cash is in the system) and the exchange rate together.
Where it sits among regimes
| Regime | Who sets the rate | Official reserve transactions |
|---|---|---|
| Fixed / peg | The government announces a rate and defends it | ≠ 0, used to hold one level |
| Managed float | Mostly the market, with intervention | ≠ 0, used to smooth movements |
| Free float | Only the market | = 0 |
- History:
- Under the Bretton Woods system (1944 to early 1970s), the dollar was tied to gold at $35 per ounce, and other currencies were tied to the dollar.
- The system collapsed after the US stopped converting dollars into gold (1971).
- After that, the world drifted into managed floating without any formal international agreement.
Worked example: managed float vs fixed rate
- At the current rate of ₹70/$, the supply of $ is $120 bn and the demand is $90 bn. There are $30 bn extra, so the rupee starts rising fast.
- Fixed rate: the RBI must buy all $30 bn to hold ₹70. It pays ₹70 × 30 bn = ₹2,100 bn (₹2.1 lakh crore) in new rupees, which adds to the money supply.
- Managed float: the RBI buys only part of the extra $30 bn.
- The rupee still rises, but more slowly.
- The market keeps deciding the level. The RBI only reduces the speed of the change.
In India
- Who manages it: the RBI. Its stated policy is to curb excess volatility, without targeting any fixed level of the rupee [5].
- Aim: to keep orderly conditions in the forex market. The RBI watches domestic and global financial markets and buys or sells foreign currency when needed [2].
- How India reached a managed float:
- 1991 BoP crisis: forex reserves could pay for only about two weeks of imports.
- July 1991: the rupee was devalued in two stages (1 and 3 July 1991), about 18% in USD terms in total [3].
- March 1992: LERMS (Liberalised Exchange Rate Management System) started. It was a dual exchange rate: part of forex earnings was converted at the official rate and the rest at the market rate [2][3].
- 1 March 1993: a unified, market-determined exchange rate replaced LERMS [2][3].
- August 1994: the rupee became convertible on the current account (for trade and similar payments), and India accepted Article VIII of the IMF's Articles of Agreement [3].
-
1999: FEMA replaced FERA, 1973. Forex violations are no longer treated as crimes; the law now "manages" forex [3].
-
The buffer: India's forex reserves were US$ 698.19 bn (week ended 25 July 2025). Of this, foreign currency assets were US$ 588.93 bn and gold US$ 85.70 bn [4].
- IMF classification:
- De jure means what India officially says. De facto means what the IMF sees in the data.
- India's de facto label moved from "floating" to "stabilised arrangement" (Dec 2022-Oct 2023), when the rate stayed in a very narrow band, and then to "crawl-like arrangement".
- The IMF 2025 Article IV report confirms that India is de jure floating and de facto crawl-like [5].
Don't confuse with
- Free float: the central bank does not intervene, so official reserve transactions = 0 (e.g. USA, Japan). In a managed float they are ≠ 0.
- Fixed exchange rate / peg: the central bank defends one announced level. In a managed float, it only smooths movements and does not target a level.
- Crawling peg / crawl-like arrangement:
- A crawling peg is an officially announced peg that is moved in small steps, often in line with inflation differences.
- Crawl-like is an IMF label for a rate that stays within a narrow band around a trend for at least 6 months, even if the country never declares it [5].
-
Managed float is the broader regime. Heavy intervention inside it can earn the crawl-like label.
-
Devaluation vs depreciation:
- Devaluation is a government decision under a fixed regime (e.g. India, July 1991).
- Depreciation is a market outcome under a flexible regime.
- Under a managed float, a fall in the rupee is a depreciation, even if the RBI slows it.
Prelims Hooks
- Managed float = dirty float. The central bank buys and sells forex to moderate movements, so official reserve transactions are non-zero (NCERT Q8).
- Under a pure float, official reserve transactions = 0. Under a managed float, they are ≠ 0.
- The world moved to managed floating after Bretton Woods collapsed (early 1970s), without any formal international agreement.
- RBI response to the rupee: when the rupee falls too fast, the RBI sells $ and reserves fall. When it rises too fast, the RBI buys $ and reserves rise.
- IMF 2025: India is de jure floating and de facto crawl-like arrangement. The RBI's stated aim is to curb excessive volatility [5].
- Sequence: LERMS (dual rate) in March 1992 → unified market rate on 1 March 1993 → current-account convertibility / IMF Article VIII in August 1994 [2][3].
Mains Points
- Why India prefers a managed float:
- Wild rupee swings hurt exporters, importers and firms with foreign-currency debt.
- A sharp fall makes oil imports costlier and pushes up inflation.
-
Large reserves (US$ 698.19 bn, July 2025 [4]) let the RBI smooth these swings without fixing a level. In 1991, reserves covered only about two weeks of imports.
-
Impossible trinity (trilemma) link:
- A country cannot have a fixed rate, free capital movement and an independent monetary policy all at once.
- India's middle path is partial capital-account openness plus a managed float, with large reserves as the cushion.
-
This lets the RBI set interest rates for domestic goals (inflation, growth) while still limiting volatility.
-
Critique:
- The IMF moved India to "stabilised" and then "crawl-like" [5]. This suggests heavy intervention.
- Too much smoothing weakens the rupee's role as a shock absorber (automatic BoP adjustment through the exchange rate).
- It can also invite outside scrutiny, such as the US Treasury monitoring list, where one test is persistent, one-sided intervention.
- A balanced approach would smooth volatility but let the rupee follow its underlying trend.
