"Policymakers are trying to achieve a fine balance by squeezing liquidity at the short-end even as they try to cap yields at the long-end," JPMorgan Chase said in a client note. "Yet, some transmission to long rates, funding costs and investment decisions is inevitable."
The RBI's decision to raise its short-term emergency funding rate by 300 basis points has already driven 10-year government bond yields up 100 basis points and short-term corporate debt up 200 basis points across the board.
It is inevitable that growth and therefore foreign inflows into the equity market will be adversely affected, JPMorgan said.
While the RBI has not explicitly said so, its actions suggest 60-per-dollar is a line in the sand for the exchange rate. Analysts think that is a mistake.

"To reverse these measures, the RBI might need to conclude that these steps were ineffective or the costs entailed were too high or the external environment has to improve markedly," said Radhika Rao, economist at DBS in Singapore.
"We don't believe either of these
