RBI’s New Arsenal to Defend the Rupee – How Far Will the Central Bank Push?

When the rupee tip‑toed toward a fresh all‑time low last weekend, the Reserve Bank of India jumped into action, rolling out a handful of measures that feel a lot like the heavy‑handed playbook it used during the 2013 taper tantrum.

First up, the RBI opened a special dollar‑window just for state‑run oil refiners. The idea is simple – give these firms a direct line to hard‑currency dollars so they don’t have to scramble on the open market, where every extra demand for dollars pushes the rupee lower.

At the same time, the central bank introduced a new reserve requirement on foreign‑exchange derivatives. In plain English, banks now have to park with the RBI the rupee‑equivalent of 20 % of the notional value of any FX‑derivative contract that exceeds $2 million. It’s a tool that the People’s Bank of China uses on the yuan, and it adds a layer of “fire‑break” to the Indian market.

The RBI also tightened a few other screws: the cap on FX‑derivative deals that lack a genuine underlying asset was slashed from $100 million to just $5 million, and any cancelled forward contract can no longer be re‑booked. In effect, the rules now make it more expensive and a bit trickier for importers and exporters to hedge their currency exposure.

These steps build on a series of earlier actions. Just a few weeks ago the RBI lifted policy rates, limited banks’ daily net open positions in the FX market to $100 million, and briefly barred non‑deliverable rupee contracts before easing that ban. The latest diaspora‑deposit drive also swelled foreign‑exchange reserves to almost $800 billion, a record high, even though $51 billion has been drawn down in the past month alone.

Analysts are already spotting the line in the sand: “₹97 per dollar is the RBI’s red line,” says Abhishek Upadhyay of ICICI Securities. The central bank’s message is clear – it won’t sit back while the rupee cracks a new low, but whether the market will respect that boundary remains to be seen.

One side‑effect of the tighter derivative regime could be higher hedging costs. Samir Lodha of QuantArt warns that regular importers might now find it both harder and pricier to protect themselves against currency swings. In fact, the cost of a one‑year dollar hedge has jumped by more than 100 basis points over the last two months as the RBI has been busy soaking up excess liquidity through sell‑buy swaps.

All of this buys the RBI a little breathing room, but it doesn’t change the bigger picture. Crude oil prices are still stubbornly high, and foreign investors have yanked more than $30 billion out of Indian equities this year. As Dhiraj Nim of ANZ points out, “Oil and capital flows will still decide the rupee’s direction.” The upcoming reserve data and next week’s rupee moves will be the real litmus test.
