Q.(a) "The central bank needs to intervene under the managed floating system." Do you agree with the given statement? Support your answer with valid reasons.

You’ve probably seen this on the news: “The rupee fell today against the dollar.” Or maybe you’ve heard that the government sometimes “intervenes” to stop the rupee from falling too much. That tug-of-war — between letting the market decide the exchange rate and the central bank stepping in — is exactly what a managed floating system is about.

The everyday intuition

Imagine a fruit market where the price of mangoes is usually set by how many people want to buy and how many are available. That’s a free market. But suppose one day, a sudden rumor makes everyone panic and prices crash. The market regulator might step in and buy a bunch of mangoes to stop the price from falling too low. That’s intervention.

Now imagine the opposite: the regulator never touches the price at all, no matter what. That’s a pure floating system. A managed floating system sits in between — the price is mostly decided by demand and supply, but the central bank (in India, the RBI) occasionally steps in to smooth out extreme swings.

The precise meaning

In a managed floating exchange rate system (also called a dirty float), the exchange rate is primarily determined by market forces — the demand for and supply of foreign currency. But the central bank does not stay completely aloof. It buys or sells foreign currency to prevent the exchange rate from moving too sharply in either direction.

The NCERT Class-12 Macroeconomics textbook (Chapter 6, Open Economy Macroeconomics) puts it clearly: under this system, the central bank intervenes actively in the foreign exchange market without any fixed target for the exchange rate. The goal is not to defend a particular level, but to manage volatility.

Why it matters

A pure floating system can be brutal. If a country’s exports suddenly fall, its currency can depreciate sharply, making imports expensive and fueling inflation. A pure fixed system, on the other hand, requires the central bank to constantly defend a target rate, which can drain its foreign exchange reserves.

The managed float gives the central bank the best of both worlds: it lets the market do most of the work (so the exchange rate reflects economic fundamentals), but it can step in to prevent disorderly movements — like a sudden panic or speculative attack.

How it works in practice (a word-picture) …

The Current Account Deficit: Spending More Than You Earn, But With a Country

Think of your monthly allowance. If you spend ₹2,000 but only earn ₹1,500, you have a deficit of ₹500. You cover that gap by borrowing from a friend or dipping into savings. A country does the same thing on a massive scale — that's the Current Account Deficit (CAD).

The Everyday Intuition

A country's current account is like its income-and-expenditure diary with the rest of the world. It records three main things:

1. Goods (exports and imports of physical items — phones, wheat, oil)
2. Services (IT exports, tourism, shipping)
3. Transfers (money sent home by workers abroad, foreign aid)

When the total money flowing out for imports, services, and transfers exceeds the money flowing in from exports, services, and transfers, you have a deficit. The country is a net borrower from the world.

The Precise Definition (NCERT Style)

The current account is part of the Balance of Payments (BoP) — the record of all economic transactions between residents of a country and the rest of the world.

Where:

• $X$ = Exports of goods
• $M$ = Imports of goods
• $X_{\text{services}}$ = Exports of services (e.g., Indian IT firms selling software to the US)
• $M_{\text{services}}$ = Imports of services (e.g., Indians using Netflix)
• Net Transfers = Money received from abroad minus money sent abroad (e.g., remittances from Indians working in the Gulf)
• Net Income = Earnings from investments abroad minus payments to foreign investors (e.g., dividends paid to a Japanese company that owns a factory in India)

If this total is negative, the country has a Current Account Deficit.

Why It Matters (The "So What?")

A CAD must be financed. How? By borrowing from abroad or selling assets to foreigners. This shows up on the other side of the BoP — the Capital Account. If a country runs a CAD of $50 billion, it must attract$50 billion of foreign investment (FDI, FII, loans) to balance the books.

Three things to watch:

1. Sustainability — A small CAD (say 2-3% of GDP) is normal for a growing economy like India. A large, persistent CAD (5%+ of GDP) signals trouble: the country is living beyond its means and may struggle to repay.

2. Currency pressure — To finance a CAD, the country needs foreign currency (dollars). High demand for dollars can weaken the rupee. A weaker rupee makes imports costlier (inflation) but helps exports.

3. The J-Curve effect — When the rupee depreciates, the trade deficit often worsens initially before improving. Why? Imports are priced in dollars and become more expensive in rupees immediately, while export volumes take time to respond. The graph of the trade balance over time looks like a "J" — dipping first, then rising. …
