Will the Rupee Cross ₹100? Here's What's Actually Happening Behind the Scenes

Where the rupee stands, and why it is under pressure

Around the policy decision USD/INR traded in roughly a 96.4 to 96.7 range. At one point it touched 96.72, a four-month high, with its all-time high close to 97. Getting to 100 from here needs about 3.5% more depreciation.

The pressure has three familiar sources. The Dollar Index, which measures the dollar against six major currencies, is near 102. The US 10-year Treasury yield was above 5.2% at Thursday 1 October's close, which makes dollar assets more attractive and tends to pull money out of emerging markets. Brent crude was around $106 a barrel, and since India imports roughly 85% of its crude oil, higher oil prices mean more demand for dollars too. We covered these three forces in our piece on why Nifty has been falling.

What a dollar swap window actually does

When the rupee is under sustained pressure, one lever the RBI can pull is making it more attractive for Non-Resident Indians to keep dollars in Indian banks. The foreign-currency deposit that banks offer NRIs is called an FCNR(B) deposit. Normally the bank has to bear the cost of hedging that currency exposure itself, which limits how much interest it can afford to offer.

A special RBI swap window changes that. The RBI itself absorbs the hedging cost, so banks can offer NRIs meaningfully higher interest on dollar deposits. Higher rates pull in more dollars, and more dollars in the banking system means more liquidity the RBI can use to manage the currency.

The RBI ran a similar window in 2013 too

The 2026 scheme wasn't invented from scratch. In 2013, during the "taper tantrum", the RBI ran a similar swap window. Global markets had reacted sharply to signals that the US Federal Reserve would slow its bond-buying programme, and currencies across emerging markets, India's included, came under pressure. That window pulled in about $34 billion and is widely credited with helping stabilise the rupee at the time.

The 2026 version has run at a far larger scale. Between 8 June and 18 September it brought in $143.5 billion of foreign-currency inflows, nearly $133 billion of it through foreign-currency deposits. It also moved faster: the 2013 scheme took around three months to reach its full inflows, while the 2026 window pulled in about as much as the entire 2013 total within its first few weeks.

The other lever: a record short dollar position

When banks convert those FCNR(B) dollars into rupees through swaps with the RBI, the RBI takes the dollars now and promises to hand them back later. That promise shows up as the RBI's net short forward dollar position. It stood at $200.06 billion in August, up $63.29 billion from $136.77 billion in July. About $176.5 billion of it matures beyond a year, and since nearly all the special deposits run three to five years (48.5% for five years, 42% for three to four years, 9% for four to five), the bulk of it falls due between 2029 and 2031.

This cushion is not free. Estimates reported alongside the RBI data put the hedging cost at about 3% a year, roughly $4 billion, and the cost of absorbing the extra rupee liquidity at about ₹35,000 crore a year. In return, the RBI has pushed India's forex reserves to a record $785.7 billion (week ended 4 September) and holds a much bigger stock of firepower than it had before the window.

What the RBI has lined up against a fast fall

Taken together, these are the levers currently in play:

Where this leaves ₹100

So can the rupee reach ₹100? No one can promise either answer, and we won't pretend to. Over long periods the rupee has tended to weaken against the dollar, because India's inflation has generally run higher than America's and the country runs a current account deficit. That is why 100 cannot be ruled out, and the pressure from the dollar, US yields and oil is real.

What is different right now is the size of the cushion. The RBI has taken in more than $143 billion, lifted reserves to a record, built a $200 billion short dollar position and raised the repo rate. All of these are tools for controlling how fast the rupee moves, not for fixing it at a level. Our read of the current setup is that the rupee is being guided along a gradual path rather than left to fall abruptly, which makes the road to 100, if it comes, look more like a question of time, and of where the dollar, US yields and oil go, than of a sudden break. That is a reading of today's setup, not a forecast, and it changes if those inputs change.

It also helps to be clear about what that time costs. The cushion has a bill attached, and the forward dollars come due from 2029 onwards. If the dollar and US yields keep climbing, the RBI has to keep spending that cushion. "It may take time" and "it can't happen" are very different statements, and only the first is supported by what we can see today.

What to watch from here

Five things will tell you more about the direction of pressure than any single rupee level:

What this has to do with you

If you're not directly trading currencies, a scheme like this mostly stays in the background, but it isn't irrelevant. A steadier rupee affects the cost of anything imported, from fuel to electronics, and it factors into how mutual funds with international exposure perform. For NRI families, understanding how FCNR(B)-type deposit schemes work is directly useful, because the interest banks can offer changes while a window like this is open.

If you have dollar commitments, such as education abroad, imports or remittances, a gradual environment is easier to plan around than a sudden one. But no one can promise the pace holds, so planning around a range rather than a single number is the sensible habit.
