Suddenly, things are looking up for India
The crisis of confidence gripping India appears to have eased considerably, raising hopes that Asia's third-largest economy may be turning a corner.
The rupee has staged a major turnaround, appreciating around 9 percent against the U.S. dollar since the end of August, when it came within a whisker of the key 70 level as panic over the currency's outlook reached fever pitch. The rupee strengthened 1.1 percent against the greenback on Monday to trade around 62.59.
Meanwhile, the benchmark Bombay Sensex has risen 11 percent over the same period, outperforming the 9.1 percent rise in the MSCI Emerging Markets Index.

An improvement in risk appetite – as investors come to terms with the U.S. Federal Reserve's plans to scale back its monetary stimulus – coupled with growing confidence in the Reserve Bank of India's new governor Raghuram Rajan and a bout of better-than-expected economic data are behind the shift in sentiment, according to market watchers.
"The Indian rupee has got its mojo back to a certain degree, part of it reflects international factors, (but) one of the key factors has been the soothing impact of (Reserve Bank of India) governor Rajan's appointment," Nick Verdi, director, FX Strategy Asia Pacific ex-Japan, Barclays told CNBC.
"He's had a Draghi-like impact on the rupee, promising measures if the rupee weakens from here," he said.
A string of positive economic indicators released in recent days is fueling optimism that the economy is gaining momentum after three straight quarters of sub-5 percent growth, economists said.
The country's trade deficit, for example, narrowed to $10.9 billion in August , from $12.27 billion in July, helped by a double-digit rise in exports. Exports increased by 13 percent, the second consecutive double-digit rise, helped by an improvement in overseas demand. Separately, industrial output unexpectedly rebounded in July, rising 2.6 percent from a year earlier, following a 2.2 percent contraction in June.

"Looking ahead, we have argued that the combination of a pick-up in the world trade cycle and the lagged effects of rupee depreciation, which started in mid-2011, will see Indian export growth recover more strongly than generally expected, pushing industrial activity up with it," said Robert Prior-Wandesforde, head, India and South East Asia Economics at Credit Suisse.
Discussing the change of mood over India, Prior-Wandesforde cautioned, while a "modicum of calm" has been regained, this could reverse as quickly as it came.
Reflecting uncertainty over the economy's outlook, India's wholesale price index (WPI), published on Monday, rose at its fastest pace in six months during August. It gained 6.1 percent, compared with expectations for a rise of 5.8 percent.
"We're still in dangerous, nervy territory," he said, pointing to a host of risk events including the Federal Open Market Committee meeting on September 17 and 18, and the Reserve Bank of India's mid-quarter policy review on September 20.

For international investors, it is vital that RBI governor Rajan has clear objectives and adopts a consistent communication strategy, say experts.
"In Rajan's first speech, the tone of the RBI's likely policy goals was outlined, but actions will speak louder than words in the coming months. If actual policy does not follow the outlined objectives then the RBI could face market skepticism about its credibility," said Paul Mackel, head of Asian FX Research at HSBC.
