Well even though the assumptions behind uncovered and covered interest rate parity do not strictly apply in its entirety, merely taking it as a rough indicator suggests, convincingly, that Pakistan PKR must devalue against INR and USD and all currencies with a lower domestic risk free interest rate (or inflation).
@Nilgiri should know more about it.
Then there is the fundamental demand shortfall of PKR internationally and a huge extant demand for USD domestically in Pak, on account of unsustainable current account deficit.
