India central bank asks top lenders to refrain from large trading bets against rupee, Reuters reports

The Reserve Bank of India has asked some large banks to not add to their existing positions against the rupee in a bid to support the currency which has fallen to all-time lows for three straight days, four bankers told Reuters.

Officials from the RBI's financial markets regulation and operations department rang big banks on Tuesday, when the currency was at risk of breaching the 84 against the dollar in the spot market, the bankers, who declined to be identified since they are not authorized to speak to the media, said.

The RBI did not immediately respond to a mail requesting comment. Reuters could not ascertain the full list of banks the RBI called.

The Indian rupee turned into the worst-performing Asian currency over the last month, pressured by the unwinding of trades that used the Chinese yuan to fund long bets on the local currency.

To slow the depreciation, the RBI has intervened across the spot, futures and non-deliverable forwards segments.

On Tuesday, RBI officials asked us to "consider the existing position size the risk limit," a senior treasury official at a large foreign bank said.

This meant that the RBI did not want them to add to their existing trading positions on the rupee, he said.

The Indian central bank often uses such informal calls to prod banks to manage excessive volatility. Lenders typically comply.

The rupee on Tuesday dropped to a lifetime low of 83.96 to the U.S. dollar, and would have likely depreciated more if not for RBI's instructions and direct intervention.

The central bank likely sold about $1.5 billion in the non-deliverable forward market before the spot market opened, a currency trader at a bank said. This intervention prevented the rupee from falling past the psychological 84 level.
