Hindenburg Research is a firm that looks for highly leveraged, absurdly valued companies that may undergo a price correction (or even a collapse) in the future.
They’re named after the Hindenburg airship, that went down in flames on 6 May, 1937.
It’s quite natural for anyone holding a significant short position against Adani to come out with something to prevent the prices from going up further.
Otherwise they would get margin-called and will have to abandon the short at a huge loss.
So what does Hindenburg do?
They make public the information that they’ve so painstakingly acquired and collated, for two things:
1. Make public aware thereby creating awareness/panic
2. Bring prices down so margins required would be lower (which can be freed up for another opportunity)
First, let's understand why RBI intervenes to defend the rupee in the first place.
A weak currency worsens our fiscal deficit, fuels inflation and slows down international trade.
Clearly, RBI has a mandate to improve the situation on behalf of the GoI and the citizens of India.
Forex market is highly volatile and a breeding ground for speculators. This is why the FX market is the most liquid in the world with around $7.5 trillion (with a T!) in daily turnover.
So, RBI has to control speculation in the USDINR segment to ensure stability of the Rupee.
