The Indian rupee has entered a period of unusually low volatility. At first glance, this looks like good news for companies, banks and investors that deal with foreign currencies. A calmer rupee makes it easier to plan costs, manage dollar payments and protect profits from sudden currency moves.
But there is a bigger question behind this calm market. Is the rupee stable because market forces have become more balanced, or is the Reserve Bank of India, or RBI, keeping the currency inside a narrow range through strong market action?
That difference matters. Low volatility can reduce the cost of currency protection, but it can also make the market less useful as a signal of the rupee’s true value.
Recent data shows how unusual the calm has been. Two-week realised volatility fell below 2% in August. One-month implied volatility stood near 4%, below its annual average of about 5.2%. On August 13, one-month implied volatility fell to 4.2%, its lowest level since early March.
For businesses, that sounds positive. For the wider foreign exchange market, the picture is more complex.
Why Hedgers Welcome a Quiet Rupee
A company that must pay dollars in the future faces currency risk. An importer may need dollars to pay for oil, machinery or other goods. An exporter may receive dollars and worry about a fall in the dollar’s value against the rupee.
Such companies often use forwards or options to protect themselves.
When currency volatility falls, the cost of such protection can also fall. Companies can get a clearer idea of their future costs. This makes budgets easier to prepare and reduces the chance of a sudden currency move hurting profit.
Banks can also manage their foreign exchange books with greater confidence when daily price moves stay small.
For this reason, a calm rupee can be a real benefit for the private sector. A company does not need to spend as much on protection when the market appears less risky.
The problem starts when low volatility creates a false sense of safety.
The RBI Factor
A major reason for the rupee’s recent calm has been the RBI’s strong presence in the foreign exchange market.
On August 25, the rupee traded near ₹95.735 per dollar and moved within an extremely narrow range. Traders said state-run banks sold dollars, likely on behalf of the RBI. Such action helped keep the currency inside a tight band.
By September 3, the rupee had reached a two-month high of ₹94.2850 per dollar. Bankers estimated that the RBI had sold at least $8 billion during the previous week. Some estimates put the total intervention at between $8 billion and $15 billion.
This matters because the market price of the rupee does not come only from private buyers and sellers. A large central bank presence can absorb some of the pressure that would otherwise push the exchange rate higher or lower.
That can make the market look calmer than the underlying economic picture.
Calm Prices Do Not Always Mean Low Risk
The central issue is simple. Low volatility does not always mean low risk.
Suppose oil prices rise sharply. India then needs more dollars to pay for oil imports. At the same time, foreign investors may take money out of Indian markets. Both forces can put pressure on the rupee.
If the RBI sells dollars to absorb that pressure, the rupee may not fall as much as market forces alone would suggest.
The visible result is a stable exchange rate.
The hidden result can be a build-up of pressure outside the spot market.
This is why traders often look at more than the daily rupee rate. They also watch oil prices, forward positions, foreign flows, option prices and the RBI’s market presence.
A Huge Dollar Inflow Has Changed the Picture
Another important factor is the RBI’s special foreign-currency deposit scheme.
Indian banks raised $127.23 billion through non-resident foreign-currency deposits. Most of this money was swapped with the RBI. This gave the central bank more foreign exchange firepower and also created a large rise in rupee liquidity.
By September 3, the banking system had a liquidity surplus of ₹9.7 trillion, or about $102.67 billion. That was above the previous peak of ₹9.2 trillion in September 2021.
The large dollar inflow gave the RBI more room to manage the rupee. It also helped the currency rise to ₹94.4850 per dollar on September 3, its strongest daily performance since July 27.
This is useful for short-term stability. Yet it also makes the question of price discovery more important.
What Price Discovery Really Means
Price discovery is the process through which buyers and sellers arrive at a market price.
In a healthy currency market, the exchange rate should respond to changes in oil prices, interest rates, trade flows, foreign investment, economic growth and global demand for the dollar.
If the rupee faces strong pressure and the central bank absorbs much of that pressure, the exchange rate may not show the full effect of those forces.
That does not mean RBI action is wrong.
A central bank has good reasons to prevent disorderly moves. A sudden fall in the rupee can raise import costs, add to inflation and create stress for companies with dollar debt.
The concern is different. If market intervention stays very strong for a long time, the exchange rate may provide less information about the true balance between dollar demand and supply.
The Hidden Risk for Banks
Recent data also shows why low volatility can create complacency.
Indian banks have raised more than $127 billion through the special foreign-currency deposit scheme. While the RBI’s swap facility protects the principal amount from foreign exchange risk, banks must manage the interest payments themselves.
Many Indian banks have left a large part of this exposure without a hedge. The cost of protection for interest payments on three-to-five-year deposits is about 3% a year. That high cost has made some banks less willing to protect the exposure.
At least half of the banks’ interest-cost exposure is reported to be unhedged.
This creates a potential problem.
If the rupee remains strong or stable, banks may feel comfortable. But if the rupee suddenly weakens toward ₹96-97 per dollar, some banks may rush to buy dollars.
That could create a fresh wave of dollar demand at exactly the time when the rupee is under pressure.
The September Test
The latest market move shows why this issue matters.
On September 9, the rupee fell past ₹95 per dollar as Brent crude moved above $100 a barrel amid renewed geopolitical tension. The rupee touched ₹95.2250 before it recovered to close at ₹95.1050, with traders pointing to likely RBI intervention.
This is a useful example of the tension inside the currency market.
Oil prices created a clear reason for rupee weakness. The RBI then acted to limit the move.
For importers and other businesses, that action was helpful. It reduced the size of the currency shock.
For price discovery, however, it raises a difficult question: what would the rupee have done without that support?
Good for Hedgers, Not Always Good for the Market
The answer is not that low rupee volatility is bad.
For companies, stable currency prices are valuable. Lower volatility can reduce hedging costs and make business plans more reliable.
The concern is that the same stability can hide risks if it comes mainly from policy action rather than a genuine balance between demand and supply.
A market needs some freedom to move. Prices must be able to reflect new information. If a shock appears and the price barely moves, the shock does not disappear. It may simply show up later through a sharper adjustment.
That is the main risk for the rupee.
The current environment therefore offers two very different messages. For a corporate treasurer, low volatility is good news. For a trader who wants a clear signal about the rupee’s true value, it may be less reassuring.
What to Watch Next
The key question for the rupee is not simply whether volatility stays low. The more useful question is why it stays low.
If oil prices ease, foreign flows improve and dollar demand becomes balanced, then low volatility would be a healthy sign.
If oil stays near or above $100 a barrel, dollar demand rises and the RBI continues to absorb much of the pressure, then low volatility could hide a larger risk.
The rupee’s recent calm is therefore best seen as a mixed signal. It gives hedgers comfort and helps companies plan. At the same time, it may reduce the amount of information that the exchange rate gives to the market.
In simple terms, the rupee may be quiet without being truly risk-free.
That distinction will matter most if the forces behind the current calm change suddenly. If the RBI’s support becomes less effective, or if oil and global dollar demand rise sharply, the market may discover that low past volatility was not the same as low future risk.
