Ordinarily, official statistics get revised because at first, provisional estimates are released, and when the full data filings come in, then improved estimates are put out.
In the case of RBI's data about RBI's trading on the currency market, such data revisions should ordinarily not arise.
But yesterday, data released by RBI modified the previous information that had been put out about RBI's trading on the currency market. Earlier, trading in June had been claimed to be 0. Now it shows purchase of $370 million and sale of $260 million. Earlier, trading in September had been claimed to be 0. Now it shows a purchase of $260 million. I wonder why this data revision took place.
The newest data - for October - shows a purchase of $450 million on the spot and $450 million on the forwards. At a time when rupee trading is estimated at above $40 billion a day (worldwide), it is hard to see how such a small scale of trading can generate a significant impact upon the price; so I wonder what is going on in terms of the rationale and the thought process.
