RBI is likely intervening to support the rupee, according to traders

Suspected RBI dollar selling is among the most familiar patterns in EM FX: the central bank has a long history of smoothing rupee moves rather than defending a level, typically through state-run banks in the spot market and, when pressure persists, through forwards and the non-deliverable market offshore. The tell for intervention rather than organic flow is two-way price action stalling at a round figure or a prior low, with offers reappearing at the same level through the session, and the distinction that matters is between smoothing volatility and drawing a line, since the former fades quickly while the latter invites a test of the bank's resolve. What has historically determined durability is the backdrop: intervention against broad dollar strength tends to slow depreciation rather than reverse it, whereas intervention against idiosyncratic rupee weakness has more often held. Worth watching are the daily reference rate relative to where spot has been trading, forward premia and any drawdown visible in subsequent reserve data, which reveal the scale of what has been spent. Sustained defence also tightens onshore rupee liquidity, a channel that shows up in money-market rates before it shows up in the currency.
